[0113] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0114] The following is a reference appendix. Figures 1 to 47 This invention describes a piping assembly 13, a thermal management device, and a vehicle according to embodiments of the present invention.

[0115] like Figures 4 to 6 As shown, the pipeline assembly 13 of this embodiment includes a base 132 and a plurality of pipe bodies 131. All pipe bodies 131 are connected to the base 132. The base 132 has a plurality of openings 1323, each corresponding to one of the pipe bodies 131. It is understood that the openings 1323 on the base 132 allow liquid to enter and exit the pipe bodies 131.

[0116] According to the embodiment of the present invention, the pipeline assembly 13 has multiple pipe bodies 131, and all multiple pipe bodies 131 are connected to the base 132. Therefore, multiple pipe bodies 131 can be integrated together to reduce the number of components to be assembled, which is beneficial to improving assembly efficiency.

[0117] like Figure 4 As shown, the tube 131 extends along a first direction, and multiple tubes 131 are arranged along a preset direction, with an angle between the preset direction and the first direction. The angle between the preset direction and the first direction can be equal to 90 degrees, greater than 90 degrees, or less than 90 degrees.

[0118] For example, such as Figures 4 to 6As shown, the first direction is the vertical direction of the piping assembly 13. The preset direction is the horizontal direction. That is to say, the preset direction can be the front-back direction of the piping assembly 13 or the left-right direction of the piping assembly 13, and the preset direction is orthogonal to the first direction.

[0119] Optionally, at least one of the pipe body 131 and the base 132 is made of a soft material. Since at least one of the pipe body 131 and the base 132 is made of a soft material, the installed piping assembly 13 can be buffered and vibration-damped by the pipe body 131 or the base 132, which is beneficial to improving the vibration isolation effect of the piping assembly 13.

[0120] For example, the pipe body 131 is made of a soft material. As a result, the pipe body 131 can absorb the vibration transmitted to the pipe assembly 13, thereby improving the vibration reduction effect of the pipe assembly 13.

[0121] For example, the base 132 is made of a soft material. As a result, the base 132 can absorb the vibration transmitted to the piping assembly 13, thereby improving the vibration reduction effect of the piping assembly 13.

[0122] For example, both the pipe body 131 and the base 132 are made of soft materials, so the pipe body 131 and the base 132 can jointly absorb the vibration transmitted to the pipe assembly 13, thereby further improving the vibration reduction effect of the pipe assembly 13.

[0123] For example, the tube body 131 and the base 132 can be made of soft materials such as rubber or plastic.

[0124] Optionally, there is one base 132, with the pipe body 131 extending along the first direction, and the base 132 disposed on one side of the pipe body 131 along the first direction. It is understood that the pipe assembly 13 has only one base 132 on one side, meaning a single base 132 is disposed on the same side of the base 132 along the first direction. By using only one base 132 in the pipe assembly 13 of this embodiment, the pipe assembly 13 can integrate multiple pipe bodies 131 together and simplify the structure of the pipe assembly 13.

[0125] Optionally, such as Figure 4 and Figure 6 As shown, there are at least two bases 132, and the pipe body 131 extends along a first direction. The two bases 132 are respectively arranged on both sides of the pipe body 131 along the first direction. It can be understood that multiple pipe bodies 131 are located between two bases 132, thereby connecting to the counterpart through the two bases 132. Compared with the solution of "multiple pipe bodies 131 being connected to the counterpart separately", the installation process of the pipe assembly 13 can be simplified, and the overall structure of the pipe assembly 13 is more stable.

[0126] For example, such as Figure 4 and Figure 6 As shown, the base 132 includes a first base 13201 and a second base 13202. The first base 13201 and the second base 13202 are respectively arranged on both sides of the tube 131 along a first direction. The first base 13201 is connected to at least two tubes 131, and the second base 13202 is connected to at least two tubes 131. Figure 4 As shown, the first end of the tube 131 (as shown) Figure 6 The upper end of the middle tube 131 is connected to the first base 13201, and the second end of the tube 131 (such as...) Figure 6 The lower end of the middle tube 131 is connected to the second base 13202. Thus, both the first and second ends of the tube 131 can be connected through the base 132, thereby improving the ease of assembly of the pipeline assembly 13.

[0127] Optionally, such as Figure 6 As shown, the base 132 is made of a soft material, and the piping assembly 13 also includes a skeleton 133, which is located within the base 132. The skeleton 133 has a higher hardness than the base 132. Because the skeleton 133 is located within the base 132 and has a higher hardness than the base 132, it can support the shape of the base 132, thereby improving the structural strength of the base 132 and the flatness of the mounting surface of the base 132. This is beneficial for improving the sealing effect of the assembled piping assembly 13.

[0128] Optionally, the thickness direction of both the skeleton 133 and the base 132 is parallel to the first direction. This can improve the flatness of the two walls of the base 132 along the first direction, which is beneficial to improving the sealing effect after the pipeline assembly 13 is assembled.

[0129] like Figure 6 As shown, the base 132 has a first surface 1321 away from the tube 131 and a second surface 1322 adjacent to the tube 131. The distance between the frame 133 and the first surface 1321 is smaller than the distance between the frame 133 and the second surface 1322. That is, the frame 133 is arranged closer to the first surface 1321, which can improve the support effect of the frame 133 and the vibration reduction effect after the base 132 is installed.

[0130] In other examples, the distance between the frame 133 and the first surface 1321 is equal to the distance between the frame 133 and the second surface 1322, which can improve the support effect of the frame 133 and the vibration reduction effect after the base 132 is installed.

[0131] like Figures 4 to 6As shown, the base 132 has a mounting hole 1324 that extends through the base 132 along a first direction. The frame 133 has a through hole 1331 that communicates with and is coaxially arranged with the mounting hole 1324. Because the through hole 1331 communicates with and is coaxially arranged with the mounting hole 1324, when the base 132 is assembled, the threaded parts can be simultaneously inserted into the mounting hole 1324 and the through hole 1331. This allows for pre-tightening of the base 132 while simultaneously fixing the frame 133, which helps improve the stability of the pipe assembly 13 after installation.

[0132] Optionally, such as Figure 4 and Figure 5 As shown, the piping assembly 13 also includes a sealing ring 134, which is arranged around the outer edge of the opening 1323. Thus, when the base 132 is assembled onto the counterpart (first flow channel plate 114 or second flow channel plate 121), the sealing ring 134 can seal the opening 1323 to prevent leakage at the opening 1323, thereby improving the sealing effect of the piping assembly 13 after assembly.

[0133] For example, the sealing ring 134 and the base 132 are integrally molded. Compared to a solution where the sealing ring 134 and the base 132 are separate parts, this reduces the number of parts and lowers production costs. When the piping assembly 13 is assembled, since the sealing ring 134 and the base 132 are integrated, there is no need to place and position the sealing ring 134, which improves assembly efficiency.

[0134] Optionally, the pipe body 131 and the base 132 are integrally formed, which facilitates the processing and manufacturing of the pipe assembly 13 and provides a better sealing effect.

[0135] For example, the tube body 131, the base 132, and the sealing ring 134 are all made of elastic rubber.

[0136] Optionally, such as Figure 4 and Figure 6 As shown, the multiple tubes 131 include a high-temperature tube 1311 and a low-temperature tube 1312, which are spaced apart. It can be understood that there is a gap between the high-temperature tube 1311 and the low-temperature tube 1312, that is, the high-temperature tube 1311 and the low-temperature tube 1312 do not contact each other.

[0137] like Figure 4As shown, the high-temperature pipe 1311 and the low-temperature pipe 1312 are spaced apart along a predetermined direction. For example, the high-temperature pipe 1311 and the low-temperature pipe 1312 are spaced apart along the left-right direction of the pipe assembly 13. It can be understood that the high-temperature pipe 1311 is used for flowing coolant with a higher temperature, and the low-temperature pipe is used for flowing coolant with a lower temperature. That is, the liquids flowing through the high-temperature pipe 1311 and the low-temperature pipe 1312 have a certain temperature difference, and the coolant in the high-temperature pipe 1311 is at a slightly higher temperature.

[0138] Since the high-temperature tube 1311 and the low-temperature tube 1312 are spaced apart from each other, compared with the solution of "the high-temperature tube 1311 and the low-temperature tube 1312 are attached", the problem of heat transfer between the coolant in the high-temperature tube 1311 and the low-temperature tube 1312 can be improved, which is conducive to reducing energy consumption.

[0139] Optionally, such as Figure 4 and Figure 6 As shown, there are at least two sets of high-temperature tubes 1311 and at least one set of low-temperature tubes 1312. The two sets of high-temperature tubes 1311 and the one set of low-temperature tubes 1312 are arranged alternately, and the distance between a low-temperature tube 1312 and its adjacent high-temperature tube 1311 is greater than the distance between two adjacent sets of high-temperature tubes 1311. Figure 4 As shown, two sets of high-temperature tubes 1311 and one set of low-temperature tubes 1312 are spaced apart along a preset direction. The distance between the low-temperature tube 1312 and its adjacent high-temperature tube 1311 is larger, and the distance between two adjacent sets of high-temperature tubes 1311 is smaller. This can improve the problem of heat transfer between the coolant in the high-temperature tubes 1311 and the low-temperature tubes 1312, which is beneficial to reduce energy consumption, and also reduce the space occupied by the pipe assembly 13, making the structure of the pipe assembly 13 more compact.

[0140] In other examples, the high-temperature tube 1311 can be in three or more groups. The low-temperature tube 1312 can be in two or more groups. This utility model does not limit the number of high-temperature tubes 1311 and low-temperature tubes 131 arranged.

[0141] Another embodiment of the thermal management device of this utility model includes a refrigerant-side module 11, a coolant-side module 12, and a piping assembly 13. The refrigerant-side module 11 includes a first flow channel plate 114, the coolant-side module 12 includes a second flow channel plate 121, and the piping assembly 13 is the piping assembly 13 of this utility model embodiment, which is connected between the first flow channel plate 114 and the second flow channel plate 121.

[0142] Understandably, thermal management devices can also be called integrated energy flow units.

[0143] like Figure 4 and Figure 7 As shown, multiple openings 1323 on the first base 13201 can communicate with the flow channels within the second flow channel plate 121, and the first base 13201 abuts against the outer wall surface of the second flow channel plate 121. Multiple openings 1323 on the second base 13202 can communicate with the flow channels within the first flow channel plate 114, and the second base 13202 abuts against the outer wall surface of the first flow channel plate 114. Thus, the coolant within the first flow channel plate 114 and the second flow channel plate 121 can flow within the piping assembly 13.

[0144] According to the embodiment of the present invention, the thermal management device has multiple tubes 131, and each tube 131 is connected to the base 132. Therefore, multiple tubes 131 can be integrated together to reduce the number of components to be assembled, which is beneficial to improving assembly efficiency.

[0145] Another embodiment of the vehicle of the present invention includes the piping assembly 13 or thermal management device of the present invention.

[0146] The technical advantages of the vehicle in this embodiment are the same as those of the pipeline assembly 13 and the thermal management device in the above embodiments, and will not be repeated here.

[0147] The following is a reference appendix. Figures 1 to 47 The present invention describes a refrigerant-side module 11, a coolant-side module 12, a first control valve 14, an air conditioning heat exchanger assembly 15, an air conditioning box module, an air distribution assembly 19, a thermal management device 10, a coolant circuit, a thermal management system, a thermal management method, and a vehicle.

[0148] like Figure 1 and Figure 40 As shown, the refrigerant-side module 11 of this embodiment includes a compressor 111, a condenser 112, an evaporator 113, and a first flow channel plate 114. The compressor 111, condenser 112, evaporator 113, and first flow channel plate 114 are integrated together. Each of the condenser 112 and the evaporator 113 has a refrigerant passage and a coolant passage. The first flow channel plate 114 has a flow channel. The refrigerant passages of the compressor 111 and the condenser 112 and the evaporator 113 are connected to form a refrigerant circuit. The coolant passages of the condenser 112 and the evaporator 113 are connected to the flow channel in the first flow channel plate 114.

[0149] It should be noted that the refrigerant passages of the condenser 112 and the evaporator 113 are for the flow of refrigerant (e.g., R290), and the coolant passages of the condenser 112 and the evaporator 113 are for the flow of coolant (e.g., antifreeze). For example, the condenser 112 is a water-cooled condenser 112 (WCC), and the evaporator 113 is a battery cooler (Chiller).

[0150] like Figure 40 As shown, when the refrigerant-side module 11 is operating, the compressor 111 starts, causing the refrigerant to circulate between the evaporator 113 and the condenser 112. The refrigerant in the evaporator 113 evaporates and absorbs heat to generate cooling capacity, which is then drawn out by the first flow channel plate 114 through the coolant passage of the evaporator 113. The refrigerant in the condenser 112 condenses and releases heat to generate heat, which is also drawn out by the first flow channel plate 114 through the coolant passage of the condenser 112.

[0151] According to the embodiment of the present invention, the refrigerant-side module 11 integrates the compressor 111, condenser 112, evaporator 113, and first flow channel plate 114, thereby reducing or even eliminating the gap between the compressor 111, condenser 112, evaporator 113, and first flow channel plate 114, thus reducing the space occupied by the refrigerant circuit and reducing the assembly difficulty. Furthermore, since the first flow channel plate 114 is integrated into the refrigerant-side module 11, the flow channel in the first flow channel plate 114 is connected to the coolant channel of the condenser 112 and the coolant channel of the evaporator 113, allowing the coolant in the coolant channel of the condenser 112 and the coolant channel of the evaporator 113 to be led outward through the first flow channel plate 114, facilitating the arrangement of the coolant circulation loop, improving the integration effect of the refrigerant-side module 11, and thus improving the space utilization rate.

[0152] Therefore, the refrigerant-side module 11 of this embodiment integrates the compressor 111, condenser 112, evaporator 113 and first flow channel plate 114, which can save layout space, improve assembly efficiency, simplify electrical control complexity, and achieve the purpose of cost reduction and efficiency improvement.

[0153] Optionally, such as Figure 1 As shown, the condenser 112 and evaporator 113 are respectively installed on opposite sides of the compressor 111. This allows the condenser 112 and evaporator 113 to be arranged at a relatively large distance, avoiding heat transfer issues caused by close proximity, thus improving the cooling effect of the evaporator 113 and reducing energy consumption. Furthermore, the arrangement of the condenser 112 and evaporator 113 on opposite sides of the compressor 111 results in a more regular shape for the refrigerant-side module 11, facilitating assembly with surrounding components and improving the compactness of the refrigerant-side module 11's layout.

[0154] Optionally, such as Figure 1As shown, the condenser 112 and the evaporator 113 are respectively installed on opposite sides of the first flow channel plate 114, which facilitates the connection of the coolant passage of the condenser 112 and the coolant passage of the evaporator 113 with the flow channel in the first flow channel plate 114, and can further reduce the space occupied by the integrated structure of the refrigerant side module 11.

[0155] Optionally, the first flow channel plate 114 encloses a receiving cavity (not shown in the figure), and the compressor 111 is disposed within the receiving cavity. It is understood that the first flow channel plate 114 covers the outer peripheral wall of the compressor 111. Thus, the first flow channel plate 114 can serve as the outer shell structure of the compressor 111, thereby reducing the space occupied by the first flow channel plate 114, improving the compactness of the internal component arrangement of the refrigerant-side module 11, and the first flow channel plate 114 can reduce the noise transmitted outward from the compressor 111, resulting in a better noise reduction effect.

[0156] Optionally, the first flow channel plate 114 is provided with a refrigerant flow channel for refrigerant circulation, and the refrigerant flow channel in the first flow channel plate 114 constitutes part of the refrigerant circuit. That is, the refrigerant passage of the condenser 112 can be connected to the refrigerant flow channel in the first flow channel plate 114, and the refrigerant passage of the evaporator 113 can be connected to the refrigerant flow channel in the first flow channel plate 114.

[0157] Therefore, the first flow channel plate 114 integrates both a coolant flow channel for circulating coolant and a refrigerant flow channel for circulating refrigerant, thereby saving on the arrangement of refrigerant piping and coolant piping and improving the integration level of the refrigerant-side module 11.

[0158] Optionally, such as Figure 1 and Figure 40 As shown, the refrigerant-side module 11 also includes a coolant heater 115, which communicates with the flow channels within the first flow channel plate 114. It is understood that when the heat provided by the condenser 112 is insufficient to meet user needs, the coolant heater 115 can be activated to provide heat to the coolant circulation loop. The coolant heater 115 can be mounted on the first flow channel plate 114 to further improve the integration of the refrigerant-side module 11, facilitating the planning and layout of subsequent wiring and piping.

[0159] For example, the coolant heater 115 can be either an air-driven type (APTC) or a water-driven type (WPTC).

[0160] Optionally, a first flow channel plate 114 encloses a receiving cavity (not shown in the figure), within which the compressor 111 and at least a portion of the coolant heater 115 are disposed. Since the compressor 111 and at least a portion of the coolant heater 115 are disposed within the receiving cavity, the first flow channel plate 114 covers the outer peripheral wall of the compressor 111. Thus, the first flow channel plate 114 can serve as the outer shell structure of the compressor 111, thereby reducing the space occupied by the first flow channel plate 114. Since a portion of the coolant heater 115 is disposed within the receiving cavity, the space within the receiving cavity can be utilized, thereby further reducing the overall dimensions of the refrigerant-side module 11.

[0161] Optionally, the first flow channel plate 114 is provided with a first flow channel, a second flow channel, and a third flow channel. The first, second, and third flow channels are independent of each other. The first flow channel is connected to the coolant passage of the evaporator 113, the second flow channel is connected to the coolant passage of the condenser 112, and the third flow channel is connected to the coolant passage of the coolant heater 115. It should be noted that each of the first, second, and third flow channels includes an inlet pipe and an outlet pipe. Taking the first flow channel as an example, the coolant on the coolant side of the evaporator 113 can enter and exit through the first flow channel.

[0162] Since the first, second, and third flow channels are independent of each other, the liquid circuits of the evaporator 113, condenser 112, and coolant heater 115 do not interfere with each other. Compared with the scheme of connecting the second and third flow channels in series, the coolant flowing out of the coolant channel of the coolant heater 115 and the coolant in the coolant channel of the condenser 112 can be prevented from mixing. That is, the higher temperature coolant flowing out of the coolant heater 115 can directly participate in the heat cycle of the air conditioner, which is beneficial to improving the heating efficiency of the air conditioner.

[0163] Optionally, such as Figure 1 As shown, the refrigerant-side module 11 also includes a high-pressure controller 116, which is electrically connected to the compressor 111 and is located near the evaporator 113. When the refrigerant-side module 11 is working, the refrigerant in the evaporator 113 evaporates and absorbs heat. The resulting cooling capacity can be used to cool the high-pressure controller 116 by utilizing the cooling capacity dissipated by the evaporator 113, thereby improving the reliability of the high-pressure controller 116.

[0164] Optionally, the high-pressure controller 116 is arranged adjacent to the first flow channel plate 114, and the high-pressure controller 116 is in communication with the coolant flow channel in the first flow channel plate 114, thereby allowing the coolant in the coolant flow channel in the first flow channel plate 114 to enter the coolant side of the high-pressure controller 116 to dissipate heat from the high-pressure controller 116. For example, the high-pressure controller 116 is mounted on the outer wall of the first flow channel plate 114.

[0165] Optionally, such as Figure 1 As shown, the evaporator 113 is located between the high-pressure controller 116 and the compressor 111. In other words, the high-pressure controller 116 and the compressor 111 are respectively installed on opposite sides of the evaporator 113. This allows the high-pressure controller 116 to be arranged as far away from the condenser 112 as possible, thereby improving the cooling effect of the high-pressure controller 116. It can be understood that the condenser 112, compressor 111, evaporator 113, and high-pressure controller 116 are arranged sequentially in the left-right direction, so that the refrigerant-side module 11 has a generally regular strip structure, which facilitates the assembly of the refrigerant-side module 11 with surrounding components and improves the compactness of the refrigerant-side module 11 arrangement.

[0166] The high-voltage controller 116 is used to control higher voltages and is prone to generating higher temperatures. By adopting the above-described structural arrangement, the cooling effect of the high-voltage controller 116 can be improved.

[0167] Optionally, such as Figure 1 and Figure 40 As shown, the refrigerant circuit also includes an electronic expansion valve 117, which is mounted on the first flow channel plate 114. The electronic expansion valve 117 is used to regulate the flow rate of the refrigerant in the refrigerant circuit. Since the electronic expansion valve 117 is integrated on the first flow channel plate 114, the piping layout can be reduced, further improving the integration level of the refrigerant-side module 11.

[0168] Optionally, the refrigerant circuit also includes a pressure sensor and a temperature sensor, which are mounted on the first flow channel plate 114. The pressure sensor and temperature sensor can be two separate sensors or integrated sensors (i.e., the pressure sensor and temperature sensor are a single structure). The pressure sensor and temperature sensor are used to detect the pressure and temperature of the refrigerant circuit, respectively. Since the pressure sensor and temperature sensor are mounted on the first flow channel plate 114, the integration level of the refrigerant-side module 11 can be further improved.

[0169] like Figure 2 and Figure 3 As shown, the coolant-side module 12 of another embodiment of the present invention includes a second flow channel plate 121, a water pump 16 and a first control valve 14. The second flow channel plate 121, the water pump 16 and the first control valve 14 are integrated together. The water pump 16 is installed on the second flow channel plate 121, and the first control valve 14 is installed on the second flow channel plate 121 and communicates with the flow channel in the second flow channel plate 121. The first control valve 14 is used to control the flow channel switching between the second flow channel plate 121 and the air conditioning heat exchanger assembly 15.

[0170] According to an embodiment of the present invention, the coolant-side module 12 integrates the second flow channel plate 121, the water pump 16, and the first control valve 14, reducing the layout of wiring and piping, which helps to reduce the space occupied by the coolant circulation loop and lowers the assembly difficulty. Furthermore, since the first control valve 14 controls the flow channel switching between the second flow channel plate 121 and the air conditioning heat exchanger assembly 15 to regulate the temperature of the air conditioning heat exchanger assembly 15, the air conditioning heat exchanger assembly 15 can switch between different modes.

[0171] Therefore, the coolant-side module 12 of this utility model integrates the second flow channel plate 121, the water pump 16 and the first control valve 14, which can save layout space, improve assembly efficiency, simplify electrical control complexity, and achieve the purpose of cost reduction and efficiency improvement.

[0172] Optionally, such as Figure 2 and Figure 3 As shown, the water pump 16 and the first control valve 14 are respectively arranged on opposite sides of the second flow channel plate 121 along its thickness direction. Since the water pump 16 and the first control valve 14 are respectively arranged on opposite sides of the thickness direction of the second flow channel plate 121, the space on both sides of the thickness direction of the second flow channel plate 121 can be rationally utilized. Furthermore, compared to the scheme where "the water pump 16 and the first control valve 14 are arranged on the same side of the thickness direction of the second flow channel plate 121," this arrangement facilitates the assembly of the coolant-side module 12 with surrounding components, reducing assembly difficulty.

[0173] like Figure 2 and Figure 3 As shown, the second flow channel plate 121 is provided with multiple sets of inlet and outlet flow channels 1211, and multiple water pumps 16 are installed sequentially on the second flow channel plate 121, with each water pump 16 corresponding to one set of inlet and outlet flow channels 1211. Since multiple water pumps 16 are integrated on the coolant-side module 12, the integration level of the coolant-side module 12 can be further improved.

[0174] For example, there can be three water pumps 16. The three water pumps 16 respectively power the liquid in the coolant circuit of the electric drive, the coolant circuit of the air conditioner, and the coolant circuit of the battery in the thermal management system.

[0175] like Figure 2 and Figure 3 As shown, the coolant-side module 12 also includes multiple second control valves 17, which are sequentially arranged on the second flow channel plate 121, and multiple water pumps 16 are connected to multiple sets of inlet and outlet flow channels 1211 in a one-to-one correspondence. Because the coolant-side module 12 integrates multiple second control valves 17, the integration level of the coolant-side module 12 can be further improved, and the layout of wiring and piping can be reduced, thus lowering the assembly difficulty.

[0176] Optionally, such as Figure 2 and Figure 3 As shown, the second control valve 17 and the water pump 16 are located on the same side of the second flow channel plate 121 along the thickness direction of the second flow channel plate 121. This improves the rationality of the component arrangement within the coolant-side module 12, prevents interference between the coolant-side module 12 and surrounding components, and facilitates assembly.

[0177] In this example of the present invention, the second control valve 17 and the water pump 16 are arranged on the same side of the second flow channel plate 121 along the thickness direction of the second flow channel plate 121. This can prevent the second control valve 17 and the water pump 16 from interfering with the position of the air conditioning heat exchanger assembly 15, and make the components of the coolant side module 12 arranged compactly.

[0178] Optionally, such as Figure 2 As shown, the coolant-side module 12 also includes a low-pressure controller 122, which is electrically connected to the water pump 16. The low-pressure controller 122 and the water pump 16 are located on the same side of the second flow channel plate 121 along its thickness direction. This improves the rationality of the component arrangement within the coolant-side module 12, prevents interference between the coolant-side module 12 and surrounding components, and facilitates assembly.

[0179] It should be noted that the low-pressure controller 122 is electrically connected to some or all of the low-pressure controlled components in the thermal management system. For example, the low-pressure controller 122 can be connected to components such as the water pump 16, the second control valve 17, and the temperature sensor in the coolant-side module 12. The low-pressure controller 122 can also be connected to components such as the pressure sensor, temperature sensor, and electronic expansion valve 117 in the refrigerant-side module 11. The low-pressure controller 122 can also be connected to components such as the blower 182, the damper motor, and the air temperature sensor.

[0180] In this example of the present invention, the low-pressure controller 122 and the water pump 16 are positioned on the same side of the second flow channel plate 121 along the thickness direction of the second flow channel plate 121. This prevents the low-pressure controller 122 and the water pump 16 from interfering with the air conditioning heat exchanger assembly 15 and makes the component arrangement of the coolant-side module 12 more compact. It is understood that the low-pressure controller 122 is used to control lower voltages. For example, the voltage range controlled by the low-pressure controller 122 is less than 40V.

[0181] Optionally, such as Figure 2 and Figure 3As shown, the coolant-side module 12 also includes a mounting bracket 123, which is connected to the second flow channel plate 121. The mounting bracket 123 has a mounting area 1234 for placing the refrigerant-side module 11. In other words, the coolant-side module 12 and the refrigerant-side module 11 can be integrated together, thereby improving the compactness of the component layout.

[0182] like Figure 2 and Figure 3 As shown, the mounting bracket 123 includes a cantilever 1231, a bracket body 1232, and a first vibration damping member 1233. The cantilever 1231 is connected to the second flow channel plate 121. The bracket body 1232 is located on the lower side of the cantilever 1231 and is connected to the cantilever 1231 via the first vibration damping member 1233. The mounting area 1234 is located on the bracket body 1232. The compressor 111 of the refrigerant-side module 11 vibrates during operation. Since the bracket body 1232 is connected to the cantilever 1231 via the first vibration damping member 1233, the probability of vibration from the refrigerant-side module 11 being transmitted to the coolant-side module 12 through the bracket body 1232 and the cantilever 1231 can be reduced. This improves the problem of abnormal noise in the coolant-side module 12 caused by the vibration of the compressor 111.

[0183] For example, the first damping element 1233 is a rubber damping pad. The support body 1232 and the cantilever 1231 are isolated and damped by the first damping element 1233 during assembly.

[0184] Optionally, such as Figure 3 As shown, the mounting bracket 123 also includes a second vibration damping member 1235, and the bracket body 1232 is connected to the second flow channel plate 121 through the second vibration damping member 1235. It can be understood that the second vibration damping member 1235 can reduce the probability of vibration of the refrigerant-side module 11 being transmitted to the second flow channel plate 121 through the bracket body 1232, thereby further improving the problem of abnormal noise generated by the coolant-side module 12 due to the vibration of the compressor 111.

[0185] For example, the second damping member 1235 is arranged on the lower side of the second flow channel plate 121, and the second damping member 1235 is a rubber damping pad. The bracket body 1232 and the second flow channel plate 121 are isolated and damped by the second damping member 1235 during assembly.

[0186] Optionally, such as Figure 2 and Figure 3As shown, the main body 1232 of the bracket includes a base plate 12321 and two columns 12322. The two columns 12322 are arranged horizontally on opposite sides of the second flow channel plate 121. The upper end of the column 12322 is connected to the cantilever 1231 through the first damping member 1233, and the lower end of the column 12322 is connected to the base plate 12321. The mounting area 1234 is located above the base plate 12321, thereby improving the stability of the mounting bracket 123 after it is assembled with the second flow channel plate 121 and the refrigerant side module 11.

[0187] It is understandable that, such as Figure 2 As shown, the horizontal direction can be either the front-to-back direction of the second flow channel plate 121 or the left-to-right direction of the second flow channel plate 121. In the example of this application, two columns 12322 are arranged on both sides of the second flow channel plate 121 along the left-to-right direction. The upper ends of the two columns 12322 are connected to the cantilever 1231, and the lower ends of the two columns 12322 are connected to the base plate 12321, so that the mounting bracket 123 is generally a rectangular frame structure.

[0188] like Figure 3 As shown, the mounting bracket 123 also includes a third vibration damping member 1236, which is disposed on the base plate 12321. The refrigerant-side module 11 is connected to the base plate 12321 through the third vibration damping member 1236. It can be understood that the third vibration damping member 1236 can reduce the probability of the vibration of the refrigerant-side module 11 being transmitted to the second flow channel plate 121 through the base plate 12321, so as to further improve the problem of abnormal noise caused by the vibration of the compressor 111 in the coolant-side module 12.

[0189] For example, the third vibration damping element 1236 is a rubber vibration damping pad. After the base plate 12321 is assembled with the refrigerant side module 11, it is isolated and damped by the third vibration damping element 1236.

[0190] like Figure 47 As shown, the upper side of the second flow channel plate 121 is connected to the cantilever 1231 via the first vibration damping member 1233. The lower side of the second flow channel plate 121 is connected to the base plate 12321 via the second vibration damping member 1235. The upper side of the refrigerant-side module 11 is connected to the second flow channel plate 121 via an integrated pipeline (the integrated pipeline has soft vibration damping structures on both the upper and lower sides). The lower side of the refrigerant-side module 11 is connected to the base plate 12321 via the third vibration damping member 1236. This can improve the problem of abnormal noise caused by the vibration of the compressor 111 in the coolant-side module 12.

[0191] like Figure 47As shown, the refrigerant-side module 11, being relatively heavy, is positioned below the thermal management unit 10. At least one level of vibration damping exists between the refrigerant-side module 11 and the second flow channel plate 121. The second flow channel plate 121 is integrated with the air conditioning unit 18. Vibration damping structures are also present between the air conditioning unit 18 and the mounting bracket 123. For example, a fourth vibration damping element (not shown) is provided between the blower 182 on the air conditioning unit 18 and the mounting bracket 123, meaning there are at least two levels of vibration damping between the refrigerant-side module 11 and the air conditioning unit 18, thereby significantly reducing the risk of vibration and NVH noise entering the passenger compartment.

[0192] The following is a reference appendix. Figures 8 to 18 The first control valve 14 of this utility model embodiment is described.

[0193] like Figures 8 to 10 As shown, in another embodiment of the present invention, the first control valve 14 includes a valve body 1401, which includes a valve shell 1411 and a valve core 1413. The valve shell 1411 is provided with a valve cavity 1412. The valve shell 1411 is provided with a first port 1, a second port 2, a third port 3 and a fourth port 4. The valve core 1413 is disposed in the valve cavity 1412 and is movable between the first position, the second position and the third position.

[0194] In the first position, the third port 3 is connected to the first port 1, and the fourth port 4 is connected to the second port 2; in the second position, the third port 3 is connected to the first port 1 and the second port 2, and the fourth port 4 is disconnected; in the third position, the fourth port 4 is connected to the first port 1 and the second port 2, and the third port 3 is disconnected.

[0195] According to another embodiment of the present invention, the first control valve 14 has a valve core 1413 located in the valve cavity 1412 and movable between the first position, the second position and the third position, so that the third port 3 and the fourth port 4 can be selectively connected to the first port 1 and the third port 3 and the fourth port 4 can be selectively connected to the second port 2. This makes the structure of the first control valve 14 compact and facilitates the switching of the air conditioning heat exchanger assembly 15 in different modes, resulting in better performance.

[0196] Optionally, such as Figures 8 to 10As shown, the first port 1, the second port 2, the third port 3, and the fourth port 4 are spaced apart circumferentially along the valve housing 1411, and the valve core 1413 is rotatable about the axis of the valve cavity 1412. Because the third port 3, the fourth port 4, the first port 1, and the second port 2 are spaced apart circumferentially along the valve housing 1411, they can be easily connected to different pipelines. In other words, the circumferential spacing of the third port 3, the fourth port 4, the first port 1, and the second port 2 provides sufficient space for pipeline insertion and removal, improving the ease of connection between the first control valve 14 and the pipeline. Furthermore, the rotatable valve core 1413 about the axis of the valve cavity 1412 simplifies its operation.

[0197] Optionally, such as Figure 2 and Figure 11 As shown, the first control valve 14 includes an actuator 1402, and a valve core 1413 includes a rotating shaft 14133 and a valve plate 14134. The rotating shaft 14133 is coaxially arranged with the valve cavity 1412, with one end extending out of the valve cavity 1412 and connected to the actuator 1402. The valve plate 14134 is connected to the rotating shaft 14133 and can rotate around the axis of the rotating shaft 14133. It can be understood that the actuator 1402 is located outside the valve cavity 1412. Since one end of the rotating shaft 14133 is connected to the actuator 1402, the valve plate 14134 can rotate relative to the valve cavity 1412 under the action of the actuator 1402. By configuring the valve core 1413 with the above-described structure, the first control valve 14 of this embodiment of the present invention simplifies the structural design of the valve core 1413 and reduces production costs.

[0198] Optionally, such as Figures 8 to 11 As shown, the valve plate 14134 abuts against the inner wall of the valve cavity 1412 on both sides of its radial direction. It can be understood that in the projection plane orthogonal to the axial direction of the valve housing 1411, the projected length of the valve plate 14134 is equal to the diameter of the valve cavity 1412, and the center of rotation of the valve plate 14134 coincides with the center of the valve cavity 1412. That is, the valve plate 14134 can divide the valve cavity 1412 into two semi-cylindrical chambers. When the valve plate 14134 rotates within the valve cavity 1412, the two chambers also undergo circumferential displacement, allowing the third port 3 and the fourth port 4 to selectively connect with the first port 1, and the third port 3 and the fourth port 4 to selectively connect with the second port 2. This simplifies the fit between the valve plate 14134 and the valve housing 1411, reduces costs, and improves performance.

[0199] Specifically, the contact position between the valve plate 14134 and the valve cavity 1412 is sealed by a sealing gasket to prevent leakage from the contact gap between the valve plate 14134 and the valve cavity 1412.

[0200] For example, a sealing gasket is provided on the side of the valve plate 14134 adjacent to the inner wall of the valve cavity 1412 and abuts against the inner wall of the valve cavity 1412; or, a sealing gasket is provided on the inner wall of the valve cavity 1412 and abuts against the valve plate 14134.

[0201] For example, the valve plate 14134 is provided with a sealing gasket on the side adjacent to the inner wall of the valve cavity 1412 and on the inner wall of the valve cavity 1412.

[0202] In another example, such as Figures 12 to 15 As shown, valve plate 14134 is connected to rotating shaft 14133 on one radial side of valve cavity 1412, and abuts against the inner wall of valve cavity 1412 on the other radial side of valve plate 14134. A partition plate 1414 is provided inside valve housing 1411. The partition plate 1414 is fixedly connected to valve cavity 1412 on one radial side of valve cavity 1412, and abuts against rotating shaft 14133 on the other radial side of valve cavity 1412. The third port 3 and the fourth port 4 are respectively arranged on both sides of valve housing 1411 along the thickness direction of partition plate 1414. It can be understood that in the projection plane orthogonal to the axial direction of valve housing 1411, the projected length of valve plate 14134 and the projected length of partition plate 1414 are both equal to the radius of valve cavity 1412. When the valve plate 14134 is in the first position, the extension line of the projection of the valve plate 14134 coincides with the extension line of the projection of the partition plate 1414.

[0203] In the example above, such as Figures 12 to 14 As shown, the partition plate 1414 is fixed relative to the valve cavity 1412, and the valve plate 14134 can rotate around the axis of the valve cavity 1412 so that the third port 3 and the fourth port 4 can selectively communicate with the first port 1, and the third port 3 and the fourth port 4 can selectively communicate with the second port 2. This makes the fit between the valve plate 14134 and the valve body 1411 simple, the cost low, and the performance good.

[0204] Optionally, such as Figure 11 and Figure 15 As shown, there are at least two valve bodies 1401, stacked axially along the valve cavity 1412. Exemplarily, there can be two or more valve bodies 1401. In this example, there are two valve bodies 1401. Because the two valve bodies 1401 are stacked, they can be integrated together to improve the structural compactness of the first control valve 14 and reduce its space requirement. It should be noted that the two valve cavities 1412 corresponding to the two valve bodies 1401 are independent and not interconnected. Exemplarily, a partition plate 14135 is provided between the first valve core 14131 and the second valve core 14132 to prevent liquid crossflow between the two valve cavities 1412.

[0205] It is understandable that a single valve body 1401 can also be called a four-way valve. Since the two valve bodies 1401 are stacked, the first control valve 14 can be called an eight-way valve.

[0206] Optionally, such as Figure 11 and Figure 15 As shown, the valve body 1401 includes a first four-way valve 14011 and a second four-way valve 14012. The first four-way valve 14011 includes a first valve shell 14111 and a first valve core 14131. The first valve shell 14111 has a first valve chamber 14121, and the first valve core 14131 is disposed within the first valve chamber 14121. The second four-way valve 14012 includes a second valve shell 14112 and a second valve core 14132. The second valve shell 14112 has a second valve chamber 14122, and the second valve core 14132 is disposed within the second valve chamber 14122. The first valve shell 14111 and the second valve shell 14112 are integrally molded parts. Because the first valve shell 14111 and the second valve shell 14112 are integrally molded parts, the number of parts to be assembled can be reduced, the processing and manufacturing are convenient, and the cost is low.

[0207] Optionally, such as Figure 2 and Figure 11 As shown, the first control valve 14 also includes an actuator 1402, which is connected to the first valve core 14131, and the first valve core 14131 is connected to the second valve core 14132. It is understood that the actuator 1402 can simultaneously control the rotation of the first valve core 14131 and the second valve core 14132, thus allowing the first control valve 14 to control two valve bodies 1401 (the first four-way valve 14011 and the second four-way valve 14012) with a single drive source, thereby reducing the production cost of the first control valve 14.

[0208] The following is a reference appendix. Figures 19 to 23 The air conditioning heat exchanger assembly 15 is described in an embodiment of the present utility model.

[0209] like Figures 19 to 22 As shown, another embodiment of the present invention, an air conditioning heat exchanger assembly 15, includes a first air conditioning heat exchanger 151 and a second air conditioning heat exchanger 152. Liquids (e.g., water or other types of coolant) at the same or different temperatures can be selectively introduced into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152. The first air conditioning heat exchanger 151 is arranged side by side on one side of the second air conditioning heat exchanger 152 along a direction orthogonal to the thickness of the second air conditioning heat exchanger 152.

[0210] According to another embodiment of the present invention, the air conditioning heat exchanger assembly 15 can selectively introduce liquids of the same or different temperatures into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, so that the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can cool at the same time, or heat at the same time, or one of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can cool while the other heats. This can realize the functions of rapid heating, rapid cooling and dehumidification of the air conditioner, which is beneficial to improving the cooling and heating efficiency of the air conditioning heat exchanger assembly 15.

[0211] Optionally, the thickness direction of the first air conditioning heat exchanger 151 is parallel to the thickness direction of the second air conditioning heat exchanger 152. Since the thickness direction of the first air conditioning heat exchanger 151 is parallel to the thickness direction of the second air conditioning heat exchanger 152, and the first air conditioning heat exchanger 151 is arranged side-by-side on one side of the second air conditioning heat exchanger 152 along a thickness direction orthogonal to the second air conditioning heat exchanger 152, the space occupied by the air conditioning heat exchanger assembly 15 along its thickness direction can be reduced, improving space utilization. Furthermore, since the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can simultaneously cool and heat, the maximum cooling and heating requirements for a single heat exchanger (the first air conditioning heat exchanger 151 or the second air conditioning heat exchanger 152) can be reduced, thereby helping to reduce the size of the air conditioning heat exchanger assembly 15.

[0212] In other examples, the thickness direction of the first air conditioning heat exchanger 151 and the thickness direction of the second air conditioning heat exchanger 152 may also have a certain angle, which is not limited in this invention.

[0213] It is understandable that the air conditioning heat exchanger assembly 15 has the following operating modes:

[0214] (1) In dehumidification mode, the first air conditioning heat exchanger 151 uses high-temperature coolant, and the second air conditioning heat exchanger 152 uses low-temperature coolant.

[0215] (2) In cooling mode, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 simultaneously run low-temperature coolant. At this time, the warm core (second air conditioning heat exchanger 152) acts as the cold core (first air conditioning heat exchanger 151).

[0216] (3) In heating mode, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 simultaneously run high-temperature coolant. At this time, the cold core (first air conditioning heat exchanger 151) is used as the warm core (second air conditioning heat exchanger 152).

[0217] Regardless of the air conditioning mode, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can be used. Compared with the traditional solution of "two heat exchangers connected in parallel and only one is used", the utilization efficiency of the air conditioning heat exchanger assembly 15 can be improved, the maximum cooling and heating requirements of a single cooling and heating core can be reduced, and the size of the air conditioning heat exchanger assembly 15 can be reduced.

[0218] Optionally, such as Figure 22 As shown, the first air conditioning heat exchanger 151 has a first liquid inlet 15111 and a first liquid outlet 15112, and the second air conditioning heat exchanger 152 has a second liquid inlet 15211 and a second liquid outlet 15212. The first liquid inlet 15111 is arranged adjacent to the second liquid inlet 15211, and the first liquid outlet 15112 is arranged adjacent to the second liquid outlet 15212. Because the first liquid inlet 15111 is adjacent to the second liquid inlet 15211, it facilitates the connection of the first liquid inlet 15111 and the second liquid inlet 15211 to the connecting parts of the air conditioning heat exchanger assembly 15. The first liquid outlet 15112 is also arranged close to the second liquid outlet 15212, facilitating the connection of the first liquid outlet 15112 and the second liquid outlet 15212 to the connecting parts of the air conditioning heat exchanger assembly 15. This facilitates the assembly of the air conditioning heat exchanger assembly 15 with the connecting parts and results in a high degree of structural compactness.

[0219] Optionally, such as Figures 19 to 22 As shown, the first air conditioning heat exchanger 151 has a first manifold 1511, which is located on the side of the first air conditioning heat exchanger 151 adjacent to the second air conditioning heat exchanger 152. The first manifold 1511 is provided with a first liquid inlet 15111 and a first liquid outlet 15112. The second air conditioning heat exchanger 152 has a second manifold 1521, which is located on the side of the second air conditioning heat exchanger 152 adjacent to the first air conditioning heat exchanger 151. The second manifold 1521 is provided with a second liquid inlet 15211 and a second liquid outlet 15212.

[0220] In other words, the first manifold 1511 and the second manifold 1521 are generally located in the area between the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152. Since the first liquid inlet 15111 and the first liquid outlet 15112 are located in the first manifold 1511, and the second liquid inlet 15211 and the second liquid outlet 15212 are located in the second manifold 1521, the first liquid inlet 15111, the first liquid outlet 15112, the second liquid inlet 15211 and the second liquid outlet 15212 are also generally arranged in the area between the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152. This makes the first liquid inlet 15111 and the second liquid inlet 15211 close to each other, and the first liquid outlet 15112 and the second liquid outlet 15212 close to each other. This facilitates the assembly of the air conditioning heat exchanger assembly 15 with the other components, and the structure is highly compact.

[0221] It is understandable that the coolant in the first inlet 15111, the first outlet 15112, the second inlet 15211, and the second outlet 15212 is distributed through the first control valve 14. Since the first inlet 15111 and the second inlet 15211 are close to each other, and the first outlet 15112 and the second outlet 15212 are close to each other, it is convenient to assemble the air conditioning heat exchanger assembly 15 with the first control valve 14.

[0222] Specifically, the first control valve 14 can introduce coolant from the second flow channel plate 121 into the first air conditioning heat exchanger 151 through the first inlet 15111 and into the second air conditioning heat exchanger 152 through the second inlet 15211. The coolant from the first air conditioning heat exchanger 151 can be led out to the first control valve 14 through the first outlet 15112, and the coolant from the second air conditioning heat exchanger 152 can be led out to the first control valve 14 through the second outlet 15212.

[0223] In one example, such as Figure 22 As shown, the first liquid inlet 15111 and the second liquid inlet 15211 are arranged side by side in the horizontal direction, and the first liquid outlet 15112 and the second liquid outlet 15212 are arranged side by side in the horizontal direction, which facilitates the connection between the liquid inlet and outlet of the air conditioning heat exchanger assembly 15 and the flow channel in the first control valve 14.

[0224] Optionally, such as Figure 19 and Figure 20As shown, a heat insulation gap 155 exists between the first manifold 1511 and the second manifold 1521. It can be understood that the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are arranged side-by-side in the left-right direction, and the first manifold 1511 and the second manifold 1521 are spaced apart in the left-right direction to form the heat insulation gap 155. Therefore, when coolant of different temperatures is introduced into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, the problem of heat transfer between the first manifold 1511 and the second manifold 1521 can be improved, reducing the energy consumption of the air conditioning heat exchanger assembly 15 during operation.

[0225] Optionally, such as Figure 22 As shown, the first liquid inlet 15111 is located above the first liquid outlet 15112, and the second liquid inlet 15211 is located above the second liquid outlet 15212. It can be understood that both the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 circulate coolant using a bottom-in, top-out method, which improves the circulation effect of the coolant within the first and second air conditioning heat exchangers 151 and 152, thus enhancing the heat exchange capacity of the air conditioning heat exchanger assembly 15.

[0226] Optionally, such as Figure 19 and Figure 20 As shown, the first air conditioning heat exchanger 151 also includes a first adapter pipe 1514, which extends vertically. The lower end of the first adapter pipe 1514 is connected to the first liquid inlet 15111, and the upper end of the first adapter pipe 1514 has a first adapter interface. The second air conditioning heat exchanger 152 also includes a second adapter pipe 1524, which extends vertically. The lower end of the second adapter pipe 1524 is connected to the second liquid inlet 15211, and the upper end of the second adapter pipe 1524 has a second adapter interface. In other words, the first adapter interface can introduce coolant into the first adapter pipe 1514, and then from the first adapter pipe 1514, guide it into the first liquid inlet 15111, thereby indirectly raising the position of the first liquid inlet 15111. The second adapter interface can introduce coolant into the second adapter pipe 1524, and then from the second adapter pipe 1524, guide it into the second liquid inlet 15211, thereby indirectly raising the position of the second liquid inlet 15211.

[0227] In this embodiment of the utility model, the air conditioning heat exchanger assembly 15 can be arranged close to the first liquid outlet 15112 and the second liquid outlet 15212 by setting the first adapter pipe 1514 and the second adapter pipe 1524, thereby facilitating the assembly of the air conditioning heat exchanger assembly 15 with the first control valve 14.

[0228] Optionally, such as Figure 19 , Figure 20 and Figure 23As shown, the air conditioning heat exchanger assembly 15 also includes a connecting flange 153. The connecting flange 153 is provided with a first liquid inlet 1531, a first liquid outlet 1532, a second liquid inlet 1533, and a second liquid outlet 1534. The first liquid inlet 1531 is connected to the first liquid inlet 15111, the first liquid outlet 1532 is connected to the first liquid outlet 15112, the second liquid inlet 1533 is connected to the second liquid inlet 15211, and the second liquid outlet 1534 is connected to the second liquid outlet 15212. By providing the connecting flange 153, the air conditioning heat exchanger assembly 15 of this embodiment can be easily connected to the counterpart (first control valve 14), which helps to reduce the difficulty of assembling the air conditioning heat exchanger assembly 15 and improve assembly efficiency.

[0229] The position of the connecting flange 153 can be designed according to the structure of the air conditioning heat exchanger assembly 15. For example, when the distance between the first liquid outlet 15112 and the second liquid outlet 15212 and the upper end of the air conditioning heat exchanger assembly 15 is too large, a corresponding exhaust structure needs to be set on the air conditioning heat exchanger assembly 15 to exhaust the gas inside the air conditioning heat exchanger assembly 15 in order to improve the heat exchange efficiency.

[0230] For example, a hollow structure can be provided inside the connecting flange 153 to reduce the weight of the connecting flange 153 and reduce the area of ​​heat exchange inside the connecting flange 153, thereby reducing energy consumption.

[0231] Optionally, such as Figures 19 to 22 As shown, the air conditioning heat exchanger assembly 15 also includes a first liquid baffle 1541, which is connected to the first manifold 1511 and the second manifold 1512. Part of the first liquid baffle 1541 is sealed between the first liquid inlet 15111 and the first liquid outlet 15112 in the vertical direction, and another part of the first liquid baffle 1541 is sealed between the second liquid inlet 15211 and the second liquid outlet 15212 in the vertical direction. It is understood that a portion of the first liquid baffle 1541 is located inside the first manifold 1511 and is positioned vertically between the first liquid inlet 15111 and the first liquid outlet 15112. This can block the coolant at the first liquid inlet 15111 and the first liquid outlet 15112, preventing cross-contamination and heat transfer of the coolant entering and exiting at the first liquid inlet 15111 and the first liquid outlet 15112. This is beneficial for improving the heat exchange effect of the air conditioning heat exchanger assembly 15.

[0232] Another part of the first liquid baffle 1541 is located inside the second manifold 1512 and is positioned vertically between the second liquid inlet 15211 and the second liquid outlet 15212. This can block the coolant at the second liquid inlet 15211 and the second liquid outlet 15212 to prevent the coolant entering and exiting at the second liquid inlet 15211 and the second liquid outlet 15212 from mixing and causing heat transfer, which is beneficial to improving the heat exchange effect of the air conditioning heat exchanger assembly 15.

[0233] Optionally, such as Figures 19 to 22 As shown, the air conditioning heat exchanger assembly 15 also includes a second liquid-blocking plate 1542 and a third liquid-blocking plate 1543. Both the second liquid-blocking plate 1542 and the third liquid-blocking plate 1543 are connected to the first manifold 1511 and the second manifold 1512. The second liquid-blocking plate 1542 is located at the top of the first manifold 1511 and the second manifold 1512, and the third liquid-blocking plate 1543 is located at the bottom of the first manifold 1511 and the second manifold 1512. It can be understood that the second liquid-blocking plate 1542 and the third liquid-blocking plate 1543 respectively seal the upper and lower ends of the first manifold 1511 to prevent coolant leakage from the upper and lower ends of the first manifold 1511. Furthermore, the second liquid-blocking plate 1542 and the third liquid-blocking plate 1543 can also respectively seal the upper and lower ends of the second manifold 1512 to prevent coolant leakage from the upper and lower ends of the second manifold 1512.

[0234] Optionally, such as Figure 19 , Figure 21 and Figure 22 As shown, the first air conditioning heat exchanger 151 includes a first manifold 1511, a first pipe group 1513 and a third manifold 1512. The first pipe group 1513 is located between the first manifold 1511 and the third manifold 1512 and is connected to the first manifold 1511 and the third manifold 1512. The second air conditioning heat exchanger 152 includes a second manifold 1521, a second pipe group 1523 and a fourth manifold 1522. The second pipe group 1523 is located between the second manifold 1521 and the fourth manifold 1522 and is connected to the second manifold 1521 and the fourth manifold 1522. It is understandable that the water flowing into the first manifold 1511 can flow into the third manifold 1512 through the first pipe group 1513. The third manifold 1512 then returns the coolant to the first manifold 1511 through the first pipe group 1513. The coolant can circulate in a bottom-up direction, thereby improving the heat exchange effect of the first air conditioning heat exchanger 151.

[0235] Similarly, the water flowing into the second manifold 1521 can flow into the fourth manifold 1522 through the second pipe group 1523. The fourth manifold 1522 then returns the coolant to the second manifold 1521 through the second pipe group 1523. The coolant can circulate from bottom to top, thereby improving the heat exchange effect of the second air conditioning heat exchanger 152.

[0236] For example, such as Figure 21 As shown, the first tube group 1513 consists of two rows arranged along the thickness direction of the first air conditioning heat exchanger 151, and both rows of the first tube group 1513 are connected to the third manifold 1512. In the projection plane orthogonal to the vertical direction of the air conditioning heat exchanger assembly 15, the external structure of the two rows of first tube groups 1513 and the third manifold 1512 is generally U-shaped, which can increase the heat exchange area of ​​the first air conditioning heat exchanger 151 and improve the heat exchange capacity of the first air conditioning heat exchanger 151.

[0237] like Figure 21 As shown, the second tube group 1523 consists of two rows arranged along the thickness direction of the second air conditioning heat exchanger 152, and both rows of the second tube group 1523 are connected to the fourth manifold 1522. In the projection plane orthogonal to the vertical direction of the air conditioning heat exchanger assembly 15, the external structure of the two rows of second tube groups 1523 and the fourth manifold 1522 is generally U-shaped, which can increase the heat exchange area of ​​the second air conditioning heat exchanger 152 and improve the heat exchange capacity of the second air conditioning heat exchanger 152.

[0238] Optionally, such as Figure 19 and Figure 22 As shown, both the first manifold 1511 and the third manifold 1512 extend vertically. The first pipe group 1513 includes multiple first branch pipes 15131, which are spaced apart vertically and connected to both the first manifold 1511 and the third manifold 1512. It is understood that coolant can flow through all the first branch pipes 15131. Since all the first branch pipes 15131 are connected to both the first manifold 1511 and the third manifold 1512, the heat exchange area of ​​the first air conditioning heat exchanger 151 can be increased, thereby improving its heat exchange capacity.

[0239] like Figure 19 and Figure 22As shown, both the second manifold 1521 and the fourth manifold 1522 extend vertically. The second pipe group 1523 includes multiple second branch pipes 15231, which are spaced apart vertically and connected to both the second manifold 1521 and the fourth manifold 1522. Because the multiple second branch pipes 15231 are connected to both the second manifold 1521 and the fourth manifold 1522, the heat exchange area of ​​the second air conditioning heat exchanger 152 can be increased, thereby improving its heat exchange capacity.

[0240] It is understood that the lengths of the first branch pipe 15131 and the second branch pipe 15231 can be designed according to the heat dissipation requirements. That is, the lengths of the first branch pipe 15131 and the second branch pipe 15231 can be the same or different. This utility model does not limit this.

[0241] The following is a reference appendix. Figures 24 to 33 This invention describes an air conditioning unit module according to an embodiment of the present invention.

[0242] like Figures 24 to 26 As shown, the air conditioning unit module of this embodiment includes an air conditioning unit 18 and an air conditioning heat exchanger assembly 15. The air conditioning unit 18 has multiple airflow channels 1801 spaced apart, and each air conditioning unit 18 has an air inlet and an air outlet communicating with each airflow channel 1801. The air conditioning heat exchanger assembly 15 includes multiple air conditioning heat exchangers, each corresponding to one of the multiple airflow channels 1801, and each heat exchanger is disposed within its corresponding airflow channel 1801.

[0243] It should be noted that the air conditioning heat exchanger assembly 15 is a dual-function heat exchanger, which can be supplied with the same or different cooling or heating media to achieve switching between cold core and warm core modes.

[0244] Air enters the airflow channel 1801 through the air inlet, undergoes heat exchange through a corresponding air conditioning heat exchanger, and then flows out of the airflow channel 1801 through the air outlet.

[0245] Compared to the related technology's "air passing through the condenser 112 and the heater core in series heat exchange structure", the air flow path in the air conditioning unit module of this utility model embodiment is shorter, the space occupied is reduced, the integration of the air conditioning unit module can be improved, and the chassis space can be freed up for battery pack layout.

[0246] In this example, the parallel multi-channel and dual-function heat exchanger design enables the air conditioner to operate in multiple modes, meeting the diverse needs of passengers, such as cooling, heating, and dehumidification.

[0247] Optionally, such as Figures 24 to 33As shown, both the air inlet and outlet are equipped with dampers, which are used to regulate the opening and closing of the air outlets and the airflow.

[0248] The air inlet connected to the air duct 1801 includes an internal circulation air inlet 1802 and an external circulation air inlet 1803. Air inside the vehicle enters the air duct 1801 through the internal circulation air inlet 1802, and air outside the vehicle enters the air duct 1801 through the external circulation air inlet 1803. The internal and external air can enter the air duct 1801 at the same time, mix, and then exchange heat through the air conditioning heat exchanger. Alternatively, only internal air or only external air can enter the air duct 1801.

[0249] The air outlets connected to the air duct 1801 include the cabin air inlet 1804 and the cabin air outlet 1805. The air that has been heated in the air duct 1801 enters the vehicle through the cabin air inlet 1804 and is discharged to the outside of the vehicle through the cabin air outlet 1805.

[0250] The following describes various operating modes of embodiments of this utility model, using two air channels 1801 as examples.

[0251] like Figure 27 As shown, the air conditioning unit 18 has two airflow channels 1801, including a first airflow channel 18011 and a second airflow channel 18012. The first airflow channel 18011 is connected to the first internal circulation air inlet 18021, the first external circulation air inlet 18031, the first cabin air inlet 18041, and the first cabin external air outlet 18051. The second airflow channel 18012 is connected to the second internal circulation air inlet 18022, the second external circulation air inlet 18032, the second cabin air inlet 18042, and the second cabin external air outlet 18052.

[0252] There are two air conditioning heat exchangers, including a first air conditioning heat exchanger 151 and a second air conditioning heat exchanger 152. The first air conditioning heat exchanger 151 is located in the first air flow channel 18011, and the second air conditioning heat exchanger 152 is located in the second air flow channel 18012.

[0253] like Figure 28 As shown, when operating in cooling mode, only a single blower 182 can be operated under low airflow requirements, achieving energy savings. For example, when the first internal circulation air inlet 18021, the first external circulation air inlet 18031, and the first cabin air inlet 18041 are open, the first air conditioning heat exchanger 151 acts as the cooling core, and the external and internal circulation air in the first airflow channel 18011 is cooled by the first air conditioning heat exchanger 151 before being sent into the vehicle interior for cooling.

[0254] When a large air volume is required, both blowers 182 operate simultaneously, i.e., the rapid cooling mode - dual cooling core, to improve cooling efficiency. At this time, the first internal circulation air inlet 18021, the first external circulation air inlet 18031, the first cabin air inlet 18041, and the second internal circulation air inlet 18022, the second external circulation air inlet 18032, and the second cabin air inlet 18042 are opened. The first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are both cooling cores. The cooled air from the first air flow channel 18011 and the second air flow channel 18012 is sent into the vehicle interior for cooling.

[0255] like Figure 29 As shown, when operating in dual-layer flow cooling mode, the first external circulation air inlet 18031, the first cabin air inlet 18041, the second internal circulation air inlet 18022, and the second cabin air inlet 18042 are open. Both the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are cold cores. The first airflow duct 18011 circulates low-humidity fresh air from outside the vehicle, which is cooled by the first air conditioning heat exchanger 151 and reaches the upper space inside the vehicle, improving the breathing comfort of the occupants and reducing fogging of the upper glass, thus improving driving safety. The second airflow duct 18012 circulates high-humidity air from inside the vehicle, which is cooled by the second air conditioning heat exchanger 152 and kept in the lower space inside the vehicle.

[0256] Similarly, such as Figure 32 As shown, when operating the dual-layer flow heating mode, the first internal circulation air inlet 18021, the first cabin air inlet 18041, the second external circulation air inlet 18032, and the second cabin air inlet 18042 are open. The first air conditioning heat exchanger 151 is the cooling core, and the second air conditioning heat exchanger 152 is the heating core. The first airflow channel 18011 circulates the high-humidity air inside the vehicle and cools it through the first air conditioning heat exchanger 151, keeping it in the lower space inside the vehicle. The second airflow channel 18012 circulates the low-humidity fresh air outside the vehicle and warms it through the second air conditioning heat exchanger 152, reaching the upper space inside the vehicle.

[0257] like Figure 30 As shown, during energy recovery in cooling mode, the first external circulation air inlet 18031, the first cabin air inlet 18041, the second internal circulation air inlet 18022, and the second cabin external air inlet 18052 are open. The first air conditioning heat exchanger 151 is the cooling core, and the second air conditioning heat exchanger 152 is the heating core. External circulation air in the first airflow channel 18011 is cooled by the first air conditioning heat exchanger 151 to cool the vehicle interior. The lower-temperature air inside the vehicle in the second airflow channel 18012 exchanges heat with the heating core, thereby enhancing the heat dissipation of the heating core and reducing energy consumption. The air after heat exchange is then exhausted outside the vehicle.

[0258] Similarly, such as Figure 33 As shown, during energy recovery in heating mode, the first internal circulation air inlet 18021, the first cabin external air inlet 18051, the second external circulation air inlet 18032, and the second cabin internal air inlet 18042 are open. The first air conditioning heat exchanger 151 is the cold core, and the second air conditioning heat exchanger 152 is the warm core. External circulation air in the second airflow channel 18012 is heated by the second air conditioning heat exchanger 152 to heat the vehicle interior. The higher-temperature air inside the vehicle recirculates in the first airflow channel 18011, exchanging heat through the cold core to recover the residual heat of the warm air inside the vehicle. The heat-exchanged air is then exhausted outside the vehicle.

[0259] like Figure 31 As shown, when operating in heating mode, only a single blower 182 can be operated under low airflow requirements, achieving energy savings. For example, when the first internal circulation air inlet 18021 and the first cabin air inlet 18041 are open, the first air conditioning heat exchanger 151 acts as the heating core, and the internal circulation air in the first airflow channel 18011 is heated by the first air conditioning heat exchanger 151 before being sent into the vehicle interior for heating.

[0260] When a large air volume is required, both blowers 182 operate simultaneously, i.e., the rapid heating mode - dual heating core, to improve heating efficiency. At this time, the first internal circulation air inlet 18021, the first cabin air inlet 18041, the second internal circulation air inlet 18022, and the second cabin air inlet 18042 are opened. The first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are both heating cores. The heated air from the first air flow channel 18011 and the second air flow channel 18012 is sent into the vehicle interior for heating.

[0261] Or, such as Figure 31 As shown, when the dehumidification mode is running, the first internal circulation air inlet 18021, the first cabin air inlet 18041, the second internal circulation air inlet 18022, and the second cabin air inlet 18042 are open. The first air conditioning heat exchanger 151 is the cooling core, and the second air conditioning heat exchanger 152 is the heating core. The internal circulation air in the first airflow channel 18011 is cooled by passing through the cooling core, and the internal circulation air in the second airflow channel 18012 is heated by passing through the heating core. The two mix and exchange heat to achieve the purpose of dehumidification.

[0262] Optionally, such as Figures 24 to 26As shown, the air conditioning unit 18 includes a heat exchange shell 183, two air inlet shells 181, and two blowers 182. The front and rear ends of the heat exchange shell 183 are open. A partition 1831 is provided inside the heat exchange shell 183. The partition 1831 is a plate-like structure and is located at the center of the heat exchange shell 183, defining two heat exchange chambers, one on the left and one on the right, within the inner cavity of the heat exchange shell 183. The two air inlet shells 181 are arranged opposite each other in the left-right direction, and the two blowers 182 are arranged opposite each other in the left-right direction and located between the two air inlet shells 181.

[0263] The right side air inlet shell 181, blower 182, and the right half of heat exchange shell 183 are connected in sequence, and their chambers are interconnected to form a first air flow channel 18011. The first air conditioning heat exchanger 151 is located in the heat exchange chamber on the right side. The left side air inlet shell 181, blower 182, and the left half of heat exchange shell 183 are connected in sequence, and their chambers are interconnected to form a second air flow channel 18012. The second air conditioning heat exchanger 152 is located in the heat exchange chamber on the left side.

[0264] In this example, the air conditioning unit 18 features a symmetrical design with dual flow channels, avoiding the lengthy paths of the cooling and heating cores in related series structures, thus significantly saving space. The symmetrical layout makes the entire air conditioning unit 18 compact, reducing the number of components, lowering the overall volume, and saving installation space.

[0265] Optionally, such as Figures 24 to 26 As shown, the cabin air inlet 1804 and the cabin air outlet 1805 are located on the heat exchange shell 183. The cabin air inlet 1804 is the open opening on the front side of the heat exchange shell 183. The cabin air inlet 1804 is divided into a first cabin air inlet 18041 on the right side and a second cabin air inlet 18042 on the left side by a separator 1831. The cabin air outlets 1805 are located on the left and right sides of the heat exchange shell 183 and in front of the air conditioning heat exchanger. The first cabin air outlet 18051 is on the right side and the second cabin air outlet 18052 is on the left side.

[0266] Optionally, such as Figures 24 to 26 As shown, the air inlet shell 181 includes a mixing shell section 1811, an internal circulation air inlet shell section 1812, an external circulation air inlet shell section 1813, and a guide shell section 1814. The internal circulation air inlet shell section 1812 extends forward to be substantially flush with the heat exchange shell 183. The front section of the internal circulation air inlet shell section 1812 is bent downward so that it rests on the upper part of the heat exchange shell 183. The rear end of the internal circulation air inlet shell section 1812 is connected to the mixing shell section 1811. The external circulation air inlet shell section 1813 extends rearward. The front end of the external circulation air inlet shell section 1813 is connected to the mixing shell section 1811. The external circulation air inlet shell section 1813 is substantially horizontal with the internal circulation air inlet shell section 1812.

[0267] The guide shell 1814 extends downwards, and its upper end connects to the mixing shell 1811. The upper end of the guide shell 1814 has a smoothly transitioning arc shape, thereby avoiding the blower 182 located below the mixing shell 1811. The lower part of the guide shell 1814 connects to one side of the blower 182. The outlet side of the blower 182 is flared to connect it to the heat exchange shell 183.

[0268] In this example of the utility model, the overall spatial layout of the air conditioning unit 18 is compact and reasonable, which reduces the space occupied by the air conditioning unit 18.

[0269] Optionally, such as Figures 24 to 26 As shown, the internal circulation air inlet 1802 is located at the front end of the internal circulation air inlet housing 1812, and the external circulation air inlet 1803 is located at the rear end of the external circulation air inlet housing 1813. The air intakes on both sides converge towards the middle, further reducing the airflow path on one side.

[0270] Optionally, such as Figure 26 As shown, the air conditioning unit 18 also includes an internal and external circulation damper 184, which is located inside the mixing shell 1811. The upper part of the mixing shell 1811 is arc-shaped to facilitate the rotation of the internal and external circulation dampers 184 within the mixing shell 1811, thereby controlling the flow rate of the internal and external circulation air intake and achieving different air mixing effects.

[0271] Optionally, such as Figure 26 As shown, the air conditioning unit 18 also includes a filter element 185, which is disposed within the air guide housing 1814. The filter element 185 filters impurities from the air, ensuring air quality inside the vehicle, reducing problems such as air conditioning heat exchanger blockage and blower 182 wear, and extending its service life.

[0272] Optionally, such as Figure 38 and Figure 39 As shown, the air conditioning unit 18 encloses a clearance space 186, which is used to accommodate at least one of the refrigerant-side module 11 and the coolant-side module 12. For example, the clearance space 186 can be used to accommodate the refrigerant-side module 11 alone, or it can be used to accommodate the coolant-side module 12 alone. Or, for example, the clearance space 186 can accommodate both the refrigerant-side module 11 and the coolant-side module 12 simultaneously.

[0273] This improves the compactness of the air conditioning unit 18 after integration with surrounding components, reduces the space occupied, and the air conditioning unit 18 can also serve as the outer shell structure of the refrigerant-side module 11 and the coolant-side module 12, thereby reducing the manufacturing cost of the thermal management device 10.

[0274] The following is a reference appendix. Figures 34 to 37 This invention describes the air distribution component according to an embodiment of the present invention.

[0275] like Figures 34 to 37 As shown, the air distribution assembly 19 of this embodiment includes a housing 190. The housing 190 contains a plurality of air distribution channels 191, which are spaced apart along a first direction. Each air distribution channel 191 includes an air distribution area 1911, a mixing area 1912, and a supply air area 1913. The air distribution area 1911, the mixing area 1912, and the supply air area 1913 are spaced apart along a second direction, which is orthogonal to the first direction. Each air distribution area 1911 includes a plurality of sub-areas, which are spaced apart along a third direction, which is orthogonal to both the second and first directions. A temperature regulating damper 192 is provided between any air distribution sub-area and the mixing area 1912, and a mode regulating damper 193 is provided between the mixing area 1912 and the supply air area 1913.

[0276] For example, the spacing between air distribution ducts 191 can be vertical, and the spacing between air distribution areas 1911, mixing areas 1912, and supply air areas 1913 can be horizontal. Or, as... Figure 34 and Figure 35 As shown, the spacing between air distribution channels 191 is slightly inclined in the vertical direction, and the spacing between air distribution areas 1911, mixing areas 1912, and supply air areas 1913 is slightly inclined in the front-to-back direction. Figure 34 As shown, the third direction is the left and right direction.

[0277] The number of air distribution channels 191 is selected according to the vehicle's seating area (such as front and rear seats). For example, for a vehicle with two rows of seats, two air distribution channels 191 are selected, one of which is used to ventilate the front seats and the other is used to ventilate the rear seats.

[0278] The air distribution area 1911 is divided into multiple independent air distribution sub-areas, each corresponding to a multiple airflow channel 1801 connected to the air conditioning unit 18. Air at different temperatures after heat exchange within each airflow channel 1801 flows to its corresponding air distribution sub-area, then converges in a mixing area to achieve a preset temperature. The airflow from each air distribution sub-area to the mixing area is adjusted by the temperature regulating damper 192, thereby regulating the temperature. Finally, the air is delivered to the target location in the vehicle through the air supply area 1913, and the delivery position (e.g., blowing on the face, feet, etc.) is adjusted by the mode regulating damper 193.

[0279] In this embodiment of the invention, the air distribution component 19 connects each air distribution sub-region (corresponding to airflow channels 1801 at different temperatures) to the air mixing region 1912 via an independent temperature regulating damper 192, allowing for precise control of the mixing ratio of air at different temperatures. By adjusting the damper opening, flexible matching of hot and cold air volumes can be achieved, ensuring that the temperature of the mixed air remains stable within a preset range.

[0280] For example, there can be two air distribution sub-regions arranged side by side. The two air distribution sub-regions are the first air distribution sub-region 19111 and the second air distribution sub-region 19112. The temperature regulating damper 192 can control the air volume of the first air distribution sub-region 19111 and the second air distribution sub-region 19112 to regulate the temperature of the air flowing into the mixing region 1912 from the two air distribution sub-regions.

[0281] The number of air distribution channels 191 is selected based on the vehicle's seating area to ensure that the airflow requirements of each area are independently met. The temperature parameters of the corresponding air distribution channel 191 can be adjusted individually to address the differentiated needs of different seating areas. The airflow distribution direction is further optimized via the mode adjustment damper 193, enhancing the user experience.

[0282] Optionally, such as Figures 34 to 37 As shown, the air distribution area 1911 of the air distribution channel 191 includes a first air distribution area 19011 and a second air distribution area 19012, which are spaced apart along a first direction. The air mixing area 1912 of the air distribution channel 191 includes a first air mixing area 19021 and a second air mixing area 19022, which correspond to the first air distribution area 19011, and the second air mixing area 19022 corresponds to the second air distribution area 19012.

[0283] In a standard vehicle, each row of seats is divided into left and right sides. The first air distribution zone 19011 and the first air mixing zone 19021 correspond to the air temperature distribution zone on one side of the vehicle, while the second air distribution zone 19012 and the second air mixing zone 19022 correspond to the air temperature distribution zone on the other side of the vehicle. Differentiated temperature adjustments are implemented for the left and right sides of the vehicle to meet the preferences of different passengers.

[0284] Taking the first air distribution area 19011 as an example, the first air distribution area 19011 includes a first air distribution sub-area 19111 and a second air distribution sub-area 19112. Since the first air distribution sub-area 19111 and the second air distribution sub-area 19112 can each emit airflows of different temperatures, the airflow volume of the first air distribution sub-area 19111 and the second air distribution sub-area 19112 can be controlled by the temperature regulating damper 192 to regulate the temperature of the first air distribution area 19011.

[0285] Similarly, the second air distribution sub-region 19112 also includes the first air distribution sub-region 19111 and the second air distribution sub-region 19112. Since the first air distribution sub-region 19111 and the second air distribution sub-region 19112 can each emit airflows of different temperatures, the airflow of the first air distribution sub-region 19111 and the second air distribution sub-region 19112 can be controlled by the temperature regulating damper 192 to regulate the temperature of the second air distribution sub-region 19112.

[0286] Optionally, such as Figures 34 to 37 As shown, the air supply area 1913 of the air distribution channel 191 includes a first surface air supply area 19031, a foot air supply area 19033, and a second surface air supply area 19032. The first surface air supply area 19031, the foot air supply area 19033, and the second surface air supply area 19032 are arranged at intervals along a first direction.

[0287] The projection of the first surface air supply area 19031 along the second direction coincides with a portion of the projection of the first air mixing area 19021 along the second direction. The projection of the second surface air supply area 19032 along the second direction coincides with a portion of the projection of the second air mixing area 19022 along the second direction. The projection of the foot air supply area 19033 along the second direction coincides with another portion of the projection of the first air mixing area 19021 along the second direction and another portion of the projection of the second air mixing area 19022 along the second direction.

[0288] The first surface air supply area 19031 and the second surface air supply area 19032 correspond to the air supply surfaces of the left and right seats of the vehicle, respectively. For foot air supply, the left and right sides are not considered. The first mixing air area 19021 and the second mixing air area 19022 supply air into the foot air supply area 19033, and the mixed air supply is used to blow air onto the feet.

[0289] The human face is more sensitive to temperature changes. Passengers on the left and right sides may have different temperature needs due to their sitting posture, body orientation, or personal preferences. The temperature and air volume of the air blowing on the left and right sides can be adjusted independently to meet the different temperature needs of different passengers on the left and right sides and improve riding comfort.

[0290] The foot-blowing function covers the entire foot area. A separate left-right design would result in redundant structure and complex airflow distribution logic. This eliminates the need for a separate left-right partition for the foot-blowing area, reducing the number of components and space required.

[0291] Therefore, the design logic of having the face blower differentiated to the left and right while the foot blower does not stems from a comprehensive consideration of human thermal comfort needs, differences in spatial coverage, and engineering costs. This approach satisfies functional requirements while also taking into account reliability and economy.

[0292] Optionally, such as Figures 35 to 37 As shown, a first mode regulating damper 1931 is provided between the first surface air supply area 19031 and the first air mixing area 19021, a second mode regulating damper 1932 is provided between the second surface air supply area 19032 and the second air mixing area 19022, and a third mode regulating damper 1933 is provided between the foot air supply area 19033 and the first air mixing area 19021 and the second air mixing area 19022.

[0293] The first-mode regulating damper 1931 and the second-mode regulating damper 1932 independently regulate the airflow on the left and right sides, adjusting the temperature difference between the left and right sides. The third-mode regulating damper 1933 controls the air intake of the first mixing zone 19021 and the second mixing zone 19022 into the foot blowing air supply zone 19033, and can select to supply air only from the first mixing zone 19021, the second mixing zone 19022, or both.

[0294] For example, such as Figure 37 As shown, the housing 190 is provided with a row of air distribution channels 1901 and a row of air distribution channels 1902. The air supply area 1913 corresponding to the row of air distribution channels 1901 includes a row of left-side air supply area 19131, a row of foot-side air supply area 19133 and a row of right-side air supply area 19132. The air supply area 1913 corresponding to the row of air distribution channels 1902 includes a row of left-side air supply area 19134, a row of foot-side air supply area 19136 and a row of right-side air supply area 19135.

[0295] Optionally, such as Figures 35 to 37 As shown, the first air distribution sub-region 19111 and the second air distribution sub-region 19112 of any air distribution region 1911 have the same volume, and the volume of multiple air distribution regions 1911 increases sequentially from top to bottom along the first direction.

[0296] To ensure that the first air distribution sub-area 19111 and the second air distribution sub-area 19112 within the same air distribution area 1911 process the same volume of air under the same conditions, and to avoid airflow distribution deviations caused by volume differences. By gradually increasing the volume of the air distribution area 1911 from top to bottom, it adapts to the airflow requirements at different height positions.

[0297] Optionally, such as Figure 35 and Figure 37 As shown, multiple mixing zones 1912 have the same volume. Simplifying the structural design, the standardized volume of the mixing zones 1912 allows for a unified structural design, facilitating production and reducing process costs.

[0298] Optionally, such as Figure 35 and Figure 37 As shown, the first air-blowing area 19031 and the second air-blowing area 19032 have the same volume, ensuring the symmetry of the air volume range of the left and right sides of the same row and avoiding air volume imbalance caused by volume differences.

[0299] The volume of the first air-blowing area 19031 is smaller than that of the foot-blowing area 19033. The larger volume accommodates more mixed air, ensuring sufficient airflow and uniform temperature in the foot area.

[0300] Optionally, such as Figure 35 and Figure 37 As shown, the housing 190 has a drain trough 194, which is located at the bottom of the housing 190 and is connected to the lowest air distribution area 1911 among multiple air distribution areas 1911. Condensate is collected naturally by gravity and flows into the drain trough 194 through the lowest point of the lowest air distribution area 1911, ensuring rapid drainage of the condensate.

[0301] Optionally, such as Figure 36 As shown, the enclosure 190 has a first cabin air vent 18051 and a second cabin air vent 18052, which are respectively located on opposite sides of the enclosure 190 along a third direction.

[0302] The first cabin's outgoing air vent 18051 is connected to the first air distribution sub-area 19111 of multiple air distribution areas 1911, and the second cabin's outgoing air vent 18052 is connected to the second air distribution sub-area 19112 of multiple air distribution areas 1911.

[0303] The first cabin air vent 18051 is used to exhaust the air in the first air distribution area 19111 to the outside of the vehicle, and the second cabin air vent 18052 is used to exhaust the air in the second air distribution area 19112 to the outside of the vehicle, thus satisfying the function of external air circulation of the vehicle's air conditioning.

[0304] like Figures 34 to 37 As shown, the air conditioning unit module of this embodiment includes an air conditioning unit 18, an air distribution assembly 19, and an air conditioning heat exchanger assembly 15. The air conditioning heat exchanger assembly 15 includes multiple air conditioning heat exchangers. The air conditioning unit 18 has multiple airflow channels 1801, which are spaced apart in the left-right direction. Each air conditioning heat exchanger corresponds to one of the multiple airflow channels 1801, and the heat exchanger is located within its corresponding airflow channel 1801. The air distribution assembly 19 is the same as in the above embodiment. The housing 190 is connected to the air conditioning unit 18. Each column of air distribution sub-areas in the third direction is a group of air distribution sub-areas, and each group of air distribution sub-areas corresponds to and is connected to one of the multiple airflow channels 1801.

[0305] Optionally, the airflow channel 1801 includes a first airflow channel 18011 and a second airflow channel 18012, and the air conditioning heat exchanger includes a first air conditioning heat exchanger 151 and a second air conditioning heat exchanger 152. The first air conditioning heat exchanger 151 is disposed within the first airflow channel 18011, and the second air conditioning heat exchanger 152 is disposed within the second airflow channel 18012. A plurality of first air distribution sub-regions 19111 located in the right column are connected to the first airflow channel 18011, and a plurality of second air distribution sub-regions 19112 located in the left column are connected to the second airflow channel 18012.

[0306] like Figure 7 , Figure 38 and Figure 39 As shown, another embodiment of the thermal management device 10 of this utility model includes: an air conditioning unit module, a refrigerant-side module 11, and a coolant-side module 12. The air conditioning unit module includes an air conditioning unit 18 and an air conditioning heat exchanger assembly 15, which is disposed inside the air conditioning unit 18. The air conditioning unit 18 has an air inlet and an air outlet. The refrigerant-side module 11 includes a compressor 111, a condenser 112, and an evaporator 113. The compressor 111 is connected to the refrigerant passage of the condenser 112 and the refrigerant passage of the evaporator 113. The coolant-side module 12 is connected to the coolant passage of the condenser 112, the coolant passage of the evaporator 113, and the air conditioning heat exchanger assembly 15.

[0307] According to the embodiment of the present invention, the thermal management device 10 integrates the air conditioning unit module, the refrigerant side module 11, and the coolant side module 12, which can save layout space. Furthermore, the air conditioning heat exchanger assembly 15 can be connected to the coolant side module 12, the coolant channel of the condenser 112, and the coolant channel of the evaporator 113, so that the air conditioning heat exchanger assembly 15 can use the coolant for heat exchange. Thus, the thermal management device 10 of the embodiment of the present invention has a compact structure, which is conducive to improving assembly efficiency, simplifying the complexity of electrical control, and achieving the purpose of cost reduction and efficiency improvement.

[0308] Optionally, such as Figure 38 and Figure 39 As shown, the air conditioning unit 18 encloses a clearance space 186, at least a portion of the refrigerant-side module 11 and at least a portion of the coolant-side module 12 are located in the clearance space 186, thereby making the structure of the thermal management device 10 compact, and the air conditioning unit 18 can also serve as the outer shell structure of the refrigerant-side module 11 and the coolant-side module 12, so as to reduce the manufacturing cost of the thermal management device 10.

[0309] Optionally, such as Figure 1 , Figure 2 and Figure 7 As shown, the refrigerant-side module 11 also includes a first flow channel plate 114, which is connected to the coolant passage of the condenser 112 and the coolant passage of the evaporator 113. The coolant-side module 12 includes a second flow channel plate 121, and the flow channels in the second flow channel plate 121 are connected to the flow channels in the first flow channel plate 114 and the flow channels in the air conditioning heat exchanger assembly 15.

[0310] According to the embodiment of the present invention, the thermal management device 10 integrates the compressor 111, condenser 112, evaporator 113 and the first flow channel plate 114 together, which can reduce the space occupied by the refrigerant circuit and reduce the assembly difficulty. Since the first flow channel plate 114 is connected to the coolant channel of the condenser 112 and the coolant channel of the evaporator 113, and the second flow channel plate 121 is connected to the first flow channel plate 114 and the air conditioning heat exchanger assembly 15, the coolant can circulate between the first flow channel plate 114, the second flow channel plate 121 and the air conditioning heat exchanger assembly 15, thereby reducing the space occupied by the coolant circulation loop, reducing the assembly difficulty and reducing the space occupied.

[0311] Optionally, such as Figure 7 As shown, the thermal management device 10 also includes a piping assembly 13, through which the second flow channel plate 121 is connected to the first flow channel plate 114. Thus, the coolant in the first flow channel plate 114 and the second flow channel plate 121 can flow within the piping assembly 13. Compared to the solution of "setting multiple separate piping", the thermal management device 10 of this embodiment, by providing the piping assembly 13, can reduce the number of piping arrangements, which is beneficial to improving assembly efficiency, and has a compact structure that occupies less space.

[0312] Optionally, such as Figures 4 to 7 As shown, the piping assembly 13 includes multiple pipe bodies 131 and two bases 132. The multiple pipe bodies 131 are arranged along a preset direction and extend along a first direction. The preset direction is orthogonal to the first direction. The two bases 132 are respectively arranged on both sides of the pipe body 131 along the first direction. One base 132 is connected to the first flow channel plate 114, and the other base 132 is connected to the second flow channel plate 121. Both the pipe body 131 and the base 132 are made of soft material.

[0313] According to the embodiment of the present invention, the thermal management device 10 has multiple tubes 131 and two bases 132 are respectively arranged on both sides of the tubes 131 along the first direction. Therefore, multiple tubes 131 can be integrated together to reduce the number of components to be assembled, which is beneficial to improving assembly efficiency. In addition, since the tubes 131 and the bases 132 are both made of soft materials, the first flow channel plate 114 and the second flow channel plate 121 can be buffered and vibration-damped by the pipeline assembly 13 to reduce the vibration transmitted from the refrigerant side module 11 to the coolant side module 12.

[0314] For example, the tube body 131 and the base 132 can be made of soft materials such as rubber or plastic.

[0315] Optionally, such as Figure 2 and Figure 23As shown, the thermal management device 10 also includes a first control valve 14, which is located on the second flow channel plate 121 and connected to the air conditioning heat exchanger assembly 15. Since the first control valve 14 is connected to the air conditioning heat exchanger assembly 15, the temperature of the air conditioning heat exchanger assembly 15 can be regulated by the first control valve 14, allowing the air conditioning heat exchanger assembly 15 to switch between different modes.

[0316] Optionally, such as Figures 19 to 22 As shown, the air conditioning heat exchanger assembly 15 includes a first air conditioning heat exchanger 151 and a second air conditioning heat exchanger 152. The second flow channel plate 121 can introduce liquids of the same or different temperatures into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 through the first control valve 14. The thickness direction of the first air conditioning heat exchanger 151 is parallel to the thickness direction of the second air conditioning heat exchanger 152. The first air conditioning heat exchanger 151 is disposed on one side of the second air conditioning heat exchanger 152 along a direction orthogonal to the thickness direction of the second air conditioning heat exchanger 152.

[0317] According to another embodiment of the present invention, the thermal management device 10 allows liquids of the same or different temperatures to be introduced into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, enabling the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 to cool or heat simultaneously, or one of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 to cool while the other heats. This enables the air conditioner to achieve rapid heating, rapid cooling and dehumidification functions, which is beneficial to improving the cooling and heating efficiency of the air conditioner.

[0318] Since the thickness direction of the first air conditioning heat exchanger 151 is parallel to the thickness direction of the second air conditioning heat exchanger 152, and the first air conditioning heat exchanger 151 is located on one side of the second air conditioning heat exchanger 152 along a thickness direction orthogonal to the second air conditioning heat exchanger 152, the space occupied by the air conditioning heat exchanger assembly 15 along its thickness direction can be reduced, thus improving space utilization. Furthermore, since the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can simultaneously cool and heat, the maximum cooling and heating requirements for a single heat exchanger (either the first air conditioning heat exchanger 151 or the second air conditioning heat exchanger 152) can be reduced, thereby helping to reduce the size of the air conditioning heat exchanger assembly 15.

[0319] It is understandable that the air conditioning heat exchanger assembly 15 has the following operating modes:

[0320] (1) In dehumidification mode, the first air conditioning heat exchanger 151 uses high-temperature coolant, and the second air conditioning heat exchanger 152 uses low-temperature coolant.

[0321] (2) In cooling mode, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 simultaneously run low-temperature coolant. At this time, the warm core (second air conditioning heat exchanger 152) acts as the cold core (first air conditioning heat exchanger 151).

[0322] (3) In heating mode, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 simultaneously run high-temperature coolant. At this time, the cold core (first air conditioning heat exchanger 151) is used as the warm core (second air conditioning heat exchanger 152).

[0323] Regardless of the air conditioning mode, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are in use. Compared with the traditional solution of "two heat exchangers connected in series and only one of them is used", the utilization efficiency of the air conditioning heat exchanger assembly 15 can be improved, the maximum cooling and heating requirements of a single cooling and heating core can be reduced, and the size of the air conditioning heat exchanger assembly 15 can be reduced.

[0324] like Figures 24 to 27 As shown, the air conditioning unit 18 has multiple airflow channels 1801 arranged sequentially. For example, the multiple airflow channels 1801 are arranged in parallel and spaced apart. The air conditioning unit 18 has an air inlet and an air outlet communicating with each airflow channel 1801. The air conditioning heat exchanger assembly 15 includes multiple air conditioning heat exchangers, each corresponding to one of the multiple airflow channels 1801, and the air conditioning heat exchangers are disposed within their corresponding airflow channels 1801.

[0325] The air conditioning heat exchanger assembly 15 is an integrated design that can be supplied with the same or different cooling or heating media to achieve switching between cold core and warm core modes.

[0326] Air enters the airflow channel 1801 through the air inlet, undergoes heat exchange through a corresponding air conditioning heat exchanger, and then flows out of the airflow channel 1801 through the air outlet.

[0327] Compared to the related technology's "air passing through the condenser 112 and the heater core in series heat exchange structure", the air flow path in the air conditioning unit module of this utility model embodiment is shorter, the space occupation is reduced, and the integration of the air conditioning unit module can be improved.

[0328] In this example of the utility model, the integrated design of the parallel multi-channel air conditioning heat exchanger assembly 15 enables multiple operating modes of the air conditioner to meet the different needs of drivers and passengers. For example, cooling, heating, and dehumidification.

[0329] Optionally, such as Figure 25 and Figure 26As shown, there are two air flow channels 1801, including a first air flow channel 18011 and a second air flow channel 18012. The air conditioning heat exchanger assembly 15 includes a first air conditioning heat exchanger 151 and a second air conditioning heat exchanger 152. The first air conditioning heat exchanger 151 is located in the first air flow channel 18011, and the second air conditioning heat exchanger 152 is located in the second air flow channel 18012. This allows the air conditioning unit module to freely switch between rapid cooling, rapid heating, and dehumidification modes.

[0330] Optionally, such as Figures 34 to 37 As shown, the thermal management device 10 also includes an air distribution assembly 19. The air distribution assembly 19 includes a housing 190, and an air distribution channel 191 is provided inside the housing 190. The air distribution channel 191 includes an air distribution area 1911, a mixing area 1912, and a supply air area 1913 arranged sequentially along the air outlet direction. The air distribution area 1911 includes a first air distribution sub-area 19111 and a second air distribution sub-area 19112 arranged side by side. The first air distribution sub-area 19111 is connected to a first air flow channel 18011, and the second air distribution sub-area 19112 is connected to a second air flow channel 18012. A first temperature regulating damper 1921 is provided between the first air distribution sub-area 19111 and the mixing area 1912, and a second temperature regulating damper 1922 is provided between the second air distribution sub-area 19112 and the mixing area 1912. A mode regulating damper 193 is provided between the mixing area 1912 and the supply air area 1913.

[0331] It is understood that different air distribution sub-regions (first air distribution sub-region 19111 and second air distribution sub-region 19112) correspond to different air flow channels 1801 (first air flow channel 18011 and second air flow channel 18012) connected to the air conditioning unit 18. Air at the corresponding temperature after heat exchange in the first air flow channel 18011 flows to the first air distribution sub-region 19111, and air at the corresponding temperature after heat exchange in the second air flow channel 18012 flows to the second air distribution sub-region 19112. Then, the airflow from both the first and second air distribution sub-regions 19111 enters the mixing region for mixing to achieve the preset temperature. Temperature regulating dampers 192 (first temperature regulating damper 1921 and second temperature regulating damper 1922) can regulate the airflow from the first and second air distribution sub-regions 19111 and 19112 to the mixing region, thereby achieving the purpose of temperature regulation. Finally, the air is delivered to the target location of the vehicle through the air supply area 1913, and the delivery position is adjusted by the mode adjustment damper 193 (e.g., blowing on the face, blowing on the feet, etc.).

[0332] In this embodiment of the invention, the air distribution component 19 connects each air distribution sub-region (corresponding to airflow channels 1801 at different temperatures) to the air mixing region 1912 via an independent temperature regulating damper 192, allowing for precise control of the mixing ratio of air at different temperatures. By adjusting the damper opening, flexible matching of hot and cold air volumes can be achieved, ensuring that the temperature of the mixed air remains stable within a preset range.

[0333] The following is a reference appendix. Figures 40 to 45 This invention describes a thermal management system according to an embodiment of the present invention.

[0334] like Figure 40 , Figure 41 and Figure 45 As shown, the thermal management system of this utility model includes a refrigerant circuit and a coolant circuit that exchanges heat with the refrigerant circuit. The coolant circuit includes a first control valve 14, a first air conditioning heat exchanger 151, and a second air conditioning heat exchanger 152. The first control valve 14 controls the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 to switch between multiple operating modes. The multiple operating modes include the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 cooling simultaneously, heating simultaneously, one cooling and the other heating, one cooling and the other stopping, or one heating and the other stopping.

[0335] According to the thermal management system of the present invention, when the thermal management system is working, both the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can exchange heat through the coolant in the coolant circuit, and the first control valve 14 can freely switch between multiple modes of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, which can improve the flexibility of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 when used, with better heat exchange effect and more diversified heat exchange methods.

[0336] For example:

[0337] (1) The first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are cooled simultaneously (i.e. both air conditioning heat exchangers are used as cold cores) so that the passenger compartment can be cooled quickly.

[0338] (2) The first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 heat up simultaneously (i.e. both air conditioning heat exchangers are used as heating cores) so that the passenger compartment can be heated up quickly.

[0339] (3) One of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 is used for cooling and the other for heating (i.e., one is used as a heating core and the other is used as a cooling core) so that the passenger compartment can be dehumidified and the temperature inside the passenger compartment can be easily controlled.

[0340] Therefore, the thermal management system of this utility model increases the working mode of the thermal management system, which can meet the usage needs in different scenarios. Furthermore, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can be used as a cold core or a warm core at the same time, which improves the cooling and heating capacity of the air conditioner. The system layout is simple and the cost is low.

[0341] Optionally, the first control valve 14 includes a first port 1 to an eighth port 8, a first air conditioning heat exchanger 151 is connected between the first port 1 and the fifth port 5 of the first control valve 14, and a second air conditioning heat exchanger 152 is connected between the second port 2 and the sixth port 6 of the first control valve 14.

[0342] According to the thermal management system of the present invention, when the thermal management system is working, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can exchange heat with the coolant in the coolant circuit through the first control valve 14, thereby the first control valve 14 can freely switch between the cooling and heating modes of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152.

[0343] It is understandable that, such as Figure 40 and Figure 45 As shown, the first control valve 14 includes at least eight ports, namely, first port 1, second port 2, third port 3, fourth port 4, fifth port 5, sixth port 6, seventh port 7 and eighth port 8.

[0344] The eight ports are divided into two groups. Port 1, Port 2, Port 3, and Port 4 form one group, which is located upstream of the coolant flow path of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, controlling the inflow of coolant into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152. Port 5, Port 6, Port 7, and Port 8 are located downstream of the coolant flow path of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, controlling the outflow of coolant from the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152.

[0345] Optionally, such as Figure 2 As shown, the first control valve 14 is a single eight-way valve, that is, the first control valve 14 is a single part, which can reduce the number of parts to be assembled, reduce the space occupied by the first control valve 14, and improve the structural compactness of the first control valve 14.

[0346] Optionally, such as Figure 45As shown, the first control valve 14 includes a first four-way valve 14011 and a second four-way valve 14012. The first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are connected in parallel between the first four-way valve 14011 and the second four-way valve 14012. The first four-way valve 14011 has a first port 1 to a fourth port 4, and the second four-way valve 14012 has a fifth port 5 to an eighth port 8. That is to say, the first control valve 14 consists of two four-way valves, which control the liquid inlet and outlet of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 respectively. When the first four-way valve 14011 or the second four-way valve 14012 is damaged, only the corresponding damaged four-way valve can be replaced without affecting the normal use of the other four-way valve, thereby reducing the later maintenance costs.

[0347] Optionally, such as Figure 11 As shown, the first control valve 14 has a first side and a second side arranged opposite to each other. The first port 1 to the fourth port 4 are arranged near the first side of the first control valve 14, and the fifth port 5 to the eighth port 8 are arranged near the second side of the first control valve 14. In other words, the first control valve 14 is generally divided into upper and lower layers. The first port 1 to the fourth port 4 are located on one layer of the first control valve 14, and the fifth port 5 to the eighth port 8 are located on the other layer. This facilitates the connection of the first port 1 to the fourth port 4 of the first control valve 14 to the inlet water circuit of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, and the fifth port 5 to the eighth port 8 to the outlet water circuit of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, reducing assembly difficulty.

[0348] Optionally, such as Figure 40 and Figure 41 As shown, the refrigerant circuit includes a compressor 111, a condenser 112 (WCC), an electronic expansion valve 117, and an evaporator 113 (Chiller). The refrigerant circuit exchanges heat with the coolant circuit through the condenser 112 and evaporator 113. It can be understood that when the thermal management system is working, the refrigerant circulates between the evaporator 113, compressor 111, and condenser 112. The refrigerant in the evaporator 113 evaporates and absorbs heat to generate cooling capacity, which the coolant circuit can extract. The refrigerant in the condenser 112 condenses and releases heat to generate heat, which the coolant circuit can extract. Therefore, the thermal management system of this embodiment can extract the cooling capacity generated by the evaporator 113 and the heat generated by the condenser 112 through the coolant circuit, reducing heat loss and achieving better heat exchange efficiency.

[0349] Optionally, such as Figure 40 and Figure 41As shown, the refrigerant circuit also includes an intermediate heat exchanger 35. The first heat exchange channel of the intermediate heat exchanger 35 is connected in series between the compressor 111 and the evaporator 113, and the second heat exchange channel of the intermediate heat exchanger 35 is connected in series between the condenser 112 and the electronic expansion valve 117. The thermal management system of this embodiment, by setting the intermediate heat exchanger 35, can exchange heat between the low-temperature refrigerant exiting the evaporator and the high-temperature refrigerant exiting the condenser 112, thereby improving the heat exchange efficiency of the refrigerant circuit and reducing energy consumption.

[0350] Optionally, such as Figure 40 and Figure 41 As shown, the condenser 112 has a first refrigerant passage 1122 and a first coolant passage 1121, and the evaporator 113 has a second refrigerant passage 1132 and a second coolant passage 1131. The compressor 111, the first refrigerant passage 1122, the electronic expansion valve 117, and the second refrigerant passage 1132 constitute a refrigerant circuit, and the coolant circuit includes the first coolant passage 1121 and the second coolant passage 1131. It can be understood that the heat exchange structure within the condenser 112 is divided into a refrigerant side (first refrigerant passage 1122) and a coolant side (first coolant passage 1121), with the first refrigerant passage transferring heat to the first coolant passage 1121. Similarly, the heat exchange structure within the evaporator 113 is divided into a refrigerant side (second refrigerant passage 1132) and a coolant side (second coolant passage 1131), with the second refrigerant passage transferring cooling energy to the second coolant passage 1131. The thermal management system of this utility model improves the heat exchange efficiency of the refrigerant circuit and the coolant circuit by arranging the condenser 112 and the evaporator 113 with the above-described structure.

[0351] like Figure 40 and Figure 41 As shown, the coolant circuit includes a first multi-way valve 171, a second multi-way valve 172, a third multi-way valve 173, a fourth multi-way valve 174, and a radiator 33;

[0352] The second end of the radiator 33 is connected to the third valve port c of the third multi-way valve 173, the first valve port a of the first multi-way valve 171 is connected to the first end of the first coolant passage 1121, the second valve port b of the first multi-way valve 171 is connected to the first end of the radiator 33, and the third valve port c of the first multi-way valve 171 is connected to the third port 3 of the first control valve 14.

[0353] The first valve port a of the second multi-way valve 172 is connected to the second end of the second coolant passage 1131, the second valve port b of the second multi-way valve 172 is connected to the fourth port 4 of the first control valve 14, the third valve port c of the second multi-way valve 172 is connected to the position between the second valve port b of the first multi-way valve 171 and the first end of the radiator 33, and the first end of the second coolant passage 1131 is connected to the eighth port 8 of the first control valve 14.

[0354] The first valve port a of the third multi-way valve 173 is connected to the position between the first end of the second coolant passage 1131 and the eighth port 8 of the first control valve 14, the second valve port b of the third multi-way valve 173 is connected to the second end of the first coolant passage 1121, and the third valve port c of the third multi-way valve 173 is connected to the second end of the radiator 33.

[0355] The first valve port a of the fourth multi-way valve 174 is connected to the seventh port 7 of the first control valve 14. The second valve port b of the fourth multi-way valve 174 is connected to the position between the second end of the second coolant passage 1131 and the first valve port a of the second multi-way valve 172. The third valve port c of the fourth multi-way valve 174 is connected to the position between the second end of the first coolant passage 1121 and the second valve port b of the third multi-way valve 173.

[0356] The thermal management system of this utility model, by adopting the above-described structure for the coolant circuit, allows the thermal management system to switch flexibly between different modes, thus meeting the usage requirements of different scenarios.

[0357] Among them, the radiator 33 can be a low-temperature radiator 33, which is used to dissipate heat from the coolant circuit.

[0358] Optionally, such as Figure 40 and Figure 41 As shown, the coolant circuit includes a battery heat exchange component 32 for heat exchange with the battery. The first end of the battery heat exchange component 32 is connected between the first end of the second coolant channel 1131 and the eighth port 8 of the first control valve 14, and is also connected to the first valve port a of the third multi-way valve 173. The second end of the battery heat exchange component 32 is connected between the second end of the second coolant channel 1131 and the first valve port a of the second multi-way valve 172. The first end of the battery heat exchange component 32 is connected via a connecting branch pipe 21 between the second valve port b of the third multi-way valve 173 and the third valve port c of the fourth multi-way valve 174. The thermal management system of this embodiment, by arranging the coolant circuit according to the above structure, can achieve the functions of cooling and heat dissipation of the battery heat exchange component 32, and allows the thermal management system to flexibly switch between different modes, meeting the usage requirements of different scenarios.

[0359] Optionally, such as Figure 40and Figure 41 As shown, the coolant circuit also includes a balance pipe 22 and a fifth multi-way valve 175. The first end of the balance pipe 22 is connected to the first valve port a of the fifth multi-way valve 175, and the second end of the balance pipe 22 is connected to the second end of the battery heat exchange component 32. The second valve port b of the fifth multi-way valve 175 is connected to the first end of the second coolant channel 1131, the first valve port a of the third multi-way valve 173, and the eighth port 8 of the first control valve 14. The third valve port c of the fifth multi-way valve 175 is connected to the first end of the battery heat exchange component 32. The thermal management system of this embodiment, by setting the balance pipe 22, allows a portion of the coolant to self-circulate in the coolant circuit of the battery heat exchange component 32, thereby improving the heat exchange efficiency of the battery heat exchange component 32 and reducing energy consumption.

[0360] In other examples, such as Figure 46 As shown, the coolant self-circulation loop of the battery heat exchange component 32 can be stopped, meaning the balance pipe 22 in the thermal management system can be discarded. In this case, the fifth multi-way valve 175 can be replaced with a two-way shut-off valve having only a second valve port b and a third valve port c.

[0361] like Figure 40 and Figure 41 As shown, a first water pump 161 is provided at the second end of the first coolant channel 1121, a second water pump 162 is provided at the first end of the second coolant channel 1131, and a third water pump 163 is provided at the second end of the battery heat exchanger component. It can be understood that the first water pump 161 provides power for the coolant entering the first coolant channel 1121, the second water pump 162 provides power for the coolant entering the second coolant channel 1131, and the third water pump 163 provides power for the coolant entering the battery heat exchanger component 32. The thermal management system of this embodiment, by providing the first water pump 161, the second water pump 162, and the third water pump 163, can improve the circulation speed of the coolant and increase the heat exchange efficiency.

[0362] Optionally, the coolant circuit further includes a sixth multi-way valve 176 and an electric drive heat exchange component 31. The electric drive heat exchange component 31 is connected between the third valve port c of the third multi-way valve 173 and the second end of the radiator 33. The first valve port a of the sixth multi-way valve 176 is connected to the first end of the radiator 33. The second valve port b of the multi-way valve is connected between the second end of the radiator 33 and the electric drive heat exchange component 31. The third valve port c of the sixth multi-way valve 176 is connected to the second valve port b of the first multi-way valve 171. The third valve port c of the second multi-way valve 172 is connected between the third valve port c of the sixth multi-way valve 176 and the second valve port b of the first multi-way valve 171. The thermal management system of this embodiment, by setting the sixth multi-way valve 176 and the electric drive heat exchange component 31, can control the thermal management system to perform heat exchange on the electric drive heat exchange component 31, thereby improving the operational stability of the electric drive assembly.

[0363] Optionally, the coolant circuit also includes a coolant heater 115 disposed between the third port c of the first multi-way valve 171 and the third port 3 of the first control valve 14. When the heat provided by the condenser 112 is insufficient to meet the heating requirements of the air conditioner, the coolant heater 115 can be activated to provide heat to the coolant circuit of the air conditioner, thereby improving the heating effect of the air conditioner.

[0364] In one example, such as Figure 42 As shown, the thermal management system has air conditioning cooling and battery cooling modes, wherein the fourth port 4 of the first control valve 14 is connected to the first port 1 and the second port 2 of the first control valve 14, and the eighth port 8 of the first control valve 14 is connected to the fifth port 5 and the sixth port 6 of the first control valve 14, so that both the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are cold cores.

[0365] The first port 1 of the first control valve 14 is cut off from the third port c of the first multi-way valve 171, and the first port a and the second port b of the first multi-way valve 171 are connected. The connecting branch pipe 21 is cut off, and the balance pipe 22 is connected.

[0366] The third valve port c of the second multi-way valve 172 is closed, while the first valve port a and the second valve port b of the second multi-way valve 172 are open.

[0367] The first valve port a of the third multi-way valve 173 is closed and the second valve port b and the third valve port c of the third multi-way valve 173 are open;

[0368] The first valve port a of the fourth multi-way valve 174 is cut off from the seventh port 7 of the first control valve 14, and the second valve port b and the third valve port c of the fourth multi-way valve 174 are also cut off.

[0369] The first valve port a, the second valve port b, and the third valve port c of the fifth multi-way valve 175 are interconnected.

[0370] The second valve port b of the sixth multi-way valve 176 is closed, while the first valve port a and the third valve port c of the sixth multi-way valve 176 are open.

[0371] The second end of the battery heat exchange component 32 is connected to the second end of the second coolant channel 1131 and to the first valve port a of the second multi-way valve 172.

[0372] It is understandable that, such as Figure 42 As shown, in air conditioning cooling and battery cooling modes:

[0373] A portion of the low-temperature coolant flowing out from the second coolant channel of the evaporator 113 flows sequentially through the second multi-way valve 172 and the first four-way valve 14011 to the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, and then flows out through the second four-way valve 14012 and flows back to the second coolant channel of the evaporator 113, thereby completing the rapid cooling of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152.

[0374] Another portion of the low-temperature coolant flowing out from the second coolant channel of the evaporator 113 enters the battery heat exchange component 32, exchanges heat with the battery heat exchange component 32, and then flows back to the second coolant channel of the evaporator 113 through the fifth multi-way valve 175, thereby completing the battery cooling.

[0375] Furthermore, since the first valve port a of the fifth multi-way valve 175 is connected to the second end of the battery heat exchange component 32 (i.e., the balance pipe 22 is connected), a portion of the low-temperature coolant can participate in the self-circulating cooling of the battery heat exchange component 32. When the battery temperature rises, the self-circulating coolant can promptly remove heat, keeping the battery within a suitable operating temperature range. This improves battery performance and extends its service life. Moreover, the aforementioned self-circulating coolant mechanism is fast-responding and can quickly regulate the battery temperature, meeting the heat exchange requirements of the battery under different operating conditions.

[0376] In the air conditioning and battery cooling modes, the thermal management system of this utility model allows the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 to simultaneously run on low-temperature coolant, thereby enabling the passenger compartment to be rapidly cooled.

[0377] It should be noted that in the air conditioning cooling and battery cooling modes, only one of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can be working while the other is not used. This utility model does not limit this.

[0378] In one example, such as Figure 43As shown, the thermal management system has air conditioning heating and battery heating modes, wherein the third port 3 of the first control valve 14 is connected to the first port 1 and the second port 2 of the first control valve 14, and the seventh port 7 of the first control valve 14 is connected to the fifth port 5 and the sixth port 6 of the first control valve 14, so that both the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 are heating cores.

[0379] The fourth port 4 of the first control valve 14 is cut off from the second port 2 of the second multi-way valve 172. The eighth port 8 of the first control valve 14 is cut off from the second valve port b of the fifth multi-way valve 175, from the first end of the first coolant passage 1121, and from the first valve port a of the third multi-way valve 173. The connecting branch pipe 21 and the balance pipe 22 are connected.

[0380] The first valve port a and the third valve port c of the first multi-way valve 171 are connected and the second port 2 of the first multi-way valve 171 is closed;

[0381] The first valve port a and the third valve port c of the second multi-way valve 172 are connected;

[0382] The first valve port a and the third valve port c of the third multi-way valve 173 are open, and the second valve port b of the third multi-way valve 173 is closed.

[0383] The first valve port a, the second valve port b, and the third valve port c of the fourth multi-way valve 174 are interconnected.

[0384] The first valve port a and the third valve port c of the fifth multi-way valve 175 are open, and the second valve port b of the fifth multi-way valve 175 is closed.

[0385] The first valve port a and the third valve port c of the sixth multi-way valve 176 are open, while the second valve port b of the sixth multi-way valve 176 is closed.

[0386] The second end of the battery heat exchange component 32 is cut off from the second end of the first coolant channel 1121 and from the first valve port a of the second multi-way valve 172.

[0387] It is understandable that, such as Figure 43 As shown, in air conditioning heating and battery heating modes:

[0388] The high-temperature coolant flowing out of the first coolant channel of the condenser 112 enters the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 through the first multi-way valve 171 and the first four-way valve 14011, and then flows out through the second four-way valve 14012, so that the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can heat up rapidly.

[0389] In this process, a portion of the coolant flowing out from the second four-way valve 14012 flows back to the first coolant channel of the condenser 112 through the third valve port c of the fourth multi-way valve 174, while another portion of the coolant flowing out from the second four-way valve 14012 enters the battery heat exchange component 32 through the second valve port b of the fourth multi-way valve 174, and then flows back to the first coolant channel of the condenser 112 through the connecting branch pipe 21, thereby completing the heating of the battery.

[0390] In addition, in the above-mentioned air conditioning heating and battery heating modes, the second valve port b of the fifth multi-way valve 175 is closed to prevent the coolant flowing out from the first end of the battery heat exchange component 32 from entering the second coolant passage 1131 of the evaporator 113 through the fifth multi-way valve 175, thus preventing the problem of coolant heat transfer.

[0391] In the air conditioning heating and battery heating modes, the thermal management system of this utility model allows the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 to simultaneously run high-temperature coolant, thereby enabling the passenger compartment to heat up rapidly.

[0392] It should be noted that in the air conditioning heating and battery heating modes, only one of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can be working while the other is not used. This utility model does not limit this.

[0393] In one example, such as Figure 44 As shown, the thermal management system has air conditioning dehumidification and battery cooling modes, wherein the first port 1 and the third port 3 of the first control valve 14 are open and the fifth port 5 and the seventh port 7 of the first control valve 14 are open, so that the first air conditioning heat exchanger 151 is a warm core, and the second port 2 and the fourth port 4 of the first control valve 14 are open and the sixth port 6 and the eighth port 8 of the first control valve 14 are open, so that the second air conditioning heat exchanger 152 is a cold core.

[0394] Connecting branch pipe 21 is cut off, and balancing pipe 22 is open;

[0395] The first valve port a, the second valve port b, and the third valve port c of the first multi-way valve 171 are connected to each other;

[0396] The first valve port a and the second valve port b of the second multi-way valve 172 are open, and the third valve port c of the second multi-way valve 172 is closed.

[0397] The second valve port b and the third valve port c of the third multi-way valve 173 are connected, and the first valve port a of the third multi-way valve 173 is closed.

[0398] The second valve port b and the third valve port c of the fourth multi-way valve 174 are connected, and the first valve port a of the third multi-way valve 173 is closed.

[0399] The first valve port a, the second valve port b, and the third valve port c of the fifth multi-way valve 175 are connected to each other.

[0400] It is understandable that, such as Figure 44 As shown, in air conditioning dehumidification and battery cooling modes:

[0401] The high-temperature coolant flowing out of the first coolant channel of the condenser 112 enters the first air conditioning heat exchanger 151 through the third port 3 and the first port 1 of the first four-way valve 14011, and then flows out through the fifth port 5 and the seventh port 7 of the second four-way valve 14012. The coolant flowing out from the seventh port 7 of the second four-way valve 14012 flows back to the first coolant channel of the condenser 112 through the fourth multi-way valve 174, thereby enabling the first air conditioning heat exchanger 151 to act as a heat core for heating.

[0402] A portion of the low-temperature coolant flowing out from the second coolant channel of the evaporator 113 enters the fourth port 4 of the first four-way valve 14011 through the second multi-way valve 172. Since the fourth port 4 and the second port 2 of the first four-way valve 14011 are connected, the low-temperature coolant can flow into the second air conditioning heat exchanger 152, and then flow out through the sixth port 6 and the eighth port 8 of the second four-way valve 14012, and flow back to the second coolant channel of the evaporator 113. Thus, the second air conditioning heat exchanger 152 can act as a cold core for refrigeration.

[0403] Another portion of the low-temperature coolant flowing out from the second coolant channel of the evaporator 113 enters the battery heat exchange component 32. After exchanging heat with the battery heat exchange component 32, the low-temperature coolant can flow back to the second coolant channel of the evaporator 113 through the fifth multi-way valve 175, thereby cooling the battery heat exchange component 32.

[0404] Furthermore, since the first valve port a of the fifth multi-way valve 175 is connected to the second end of the battery heat exchange component 32 (i.e., the balance pipe 22 is connected), a portion of the low-temperature coolant can participate in the self-circulating cooling of the battery heat exchange component 32. When the battery temperature rises, the self-circulating coolant can promptly remove heat, keeping the battery within a suitable operating temperature range. This improves battery performance and extends its service life. Moreover, the aforementioned self-circulating coolant mechanism is fast-responding and can quickly regulate the battery temperature, meeting the heat exchange requirements of the battery under different operating conditions.

[0405] In the air conditioning dehumidification and battery cooling modes of the embodiment of this utility model, the thermal management system allows the first air conditioning heat exchanger 151 to carry high-temperature coolant and the second air conditioning heat exchanger 152 to carry low-temperature coolant, thereby absorbing moisture in the passenger compartment and achieving the purpose of dehumidifying the passenger compartment.

[0406] Optionally, the refrigerant in the refrigerant circuit is propane (R290), 1,1,1,2 tetrafluoroethane, or carbon dioxide, and the coolant in the coolant circuit is antifreeze.

[0407] like Figure 40 and Figure 41 As shown, the thermal management system also includes an expansion tank 34, which is connected to the coolant circuit. The function of the expansion tank 34 is to compensate for the expansion of water in the coolant circuit in order to maintain stable water pressure in the coolant circuit.

[0408] like Figure 40 and Figure 41 As shown, the thermal management system also includes a dryer receiver 36, which is connected to the first refrigerant passage 1122 of the condenser. Both the dryer receiver 36 and the intermediate heat exchanger 35 are integrated within the cavity enclosed by the first flow channel plate. This further improves the integration of the refrigerant-side modules and reduces space requirements.

[0409] According to another embodiment of the present invention, a thermal management method applicable to the thermal management system of the present invention is provided. The thermal management method includes: adjusting a first control valve 14 based on the thermal management requirements of the vehicle to control the first air conditioning heat exchanger 151 to operate as a cold core, a warm core, or to stop operating, and controlling the second air conditioning heat exchanger 152 to operate as a cold core, a warm core, or to stop operating.

[0410] The following is a reference appendix. Figures 40 to 45 The coolant circuit of an embodiment of this utility model is described.

[0411] Another embodiment of the present invention includes a coolant circuit comprising a first air conditioning heat exchanger 151 and a second air conditioning heat exchanger 152. The first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 have multiple operating modes, including simultaneous cooling and heating, one cooling and the other heating, one cooling and the other stopping, one heating and the other stopping, or both stopping simultaneously.

[0412] According to the coolant circuit of the embodiment of the present invention, when the coolant circuit is working, both the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can exchange heat through the coolant in the coolant circuit. Furthermore, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can freely switch between multiple modes, which can improve the flexibility of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 when in use, improve the heat exchange effect, and make the heat exchange method more diversified.

[0413] Optionally, the coolant circuit also includes a first control valve 14, which controls the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 to switch between multiple operating modes. When the coolant circuit is operating, the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can exchange heat with the coolant in the coolant circuit through the first control valve 14. It is understood that the first control valve 14 can switch the flow path within the coolant circuit, allowing all the high-temperature coolant in the coolant to flow into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, so that the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can simultaneously generate heat, thereby improving the heating efficiency of the air conditioning heat exchangers.

[0414] The first control valve 14 can switch the flow path in the coolant circuit to freely switch the operating modes of the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152.

[0415] For example, the first control valve 14 can introduce all the high-temperature coolant in the coolant circuit into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, so that the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can heat at the same time, thereby improving the heating efficiency of the air conditioning heat exchanger.

[0416] For example, the first control valve 14 can introduce all the low-temperature coolant in the coolant circuit into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, so that the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can cool at the same time, thereby improving the cooling efficiency of the air conditioning heat exchanger.

[0417] For example, the first control valve 14 can introduce the high-temperature coolant in the coolant circuit into the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 in the coolant circuit, so that the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 can cool and heat respectively, thereby dehumidifying the passenger compartment.

[0418] In other examples, the first control valve 14 can also control the first air conditioning heat exchanger 151 to heat (cool) independently, while the second air conditioning heat exchanger 152 does not work.

[0419] The first control valve 14 can also independently control the second air conditioning heat exchanger 152 to heat (cool), while the first air conditioning heat exchanger 151 is not working.

[0420] It is understood that the technical advantages of the coolant circuit in the embodiment of this utility model are the same as those of the coolant circuit in the thermal management system in the above embodiments, and will not be repeated here.

[0421] Another embodiment of the thermal management method of this utility model includes: controlling the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152 to switch between multiple operating modes based on the vehicle's thermal management needs. The multiple operating modes include simultaneous cooling by the first air conditioning heat exchanger 151 and the second air conditioning heat exchanger 152, simultaneous heating by both, one cooling and the other heating, one cooling and the other stopping operation, or one heating and the other stopping operation. The technical advantages of the thermal management method of this utility model embodiment are the same as those of the thermal management system in the above embodiments, and will not be repeated here.

[0422] For example, the thermal management method is performed by the thermal management system of the above embodiments.

[0424] Another embodiment of the vehicle of the present invention includes a controller that executes the thermal management method of the above embodiment.

[0425] The technical advantages of the vehicle in this embodiment are the same as those of the thermal management device, thermal management system and thermal management method in the above embodiments, and will not be repeated here.

[0426] The refrigerant-side module of an embodiment of the present invention includes a compressor, a condenser, an evaporator, and a first flow channel plate. The compressor, the condenser, the evaporator, and the first flow channel plate are integrated together. Each of the condenser and the evaporator has a refrigerant passage and a coolant passage. The first flow channel plate has a flow channel. The refrigerant passages of the compressor, the condenser, and the evaporator are connected to form a refrigerant circuit. The coolant passages of the condenser and the evaporator are connected to the flow channel in the first flow channel plate.

[0427] According to an embodiment of the present invention, the refrigerant-side module integrates the compressor, condenser, evaporator, and first flow channel plate, thereby reducing or even eliminating the gap between the compressor, condenser, evaporator, and first flow channel plate. This reduces the space occupied by the refrigerant circuit, lowers the assembly difficulty, and since the first flow channel plate is integrated into the refrigerant-side module, the flow channels within the first flow channel plate are connected to the coolant channels of the condenser and the evaporator. This allows the coolant in the coolant channels of the condenser and the evaporator to be led outward through the first flow channel plate, facilitating the arrangement of the coolant circulation loop, improving the integration effect of the refrigerant-side module, and thus increasing space utilization.

[0438] Optionally, the refrigerant circuit further includes a pressure sensor and a temperature sensor, which are mounted on the first flow channel plate.

[0439] Another embodiment of the coolant-side module of the present invention includes a second flow channel plate, a water pump and a first control valve. The second flow channel plate, the water pump and the first control valve are integrated together. The water pump is installed on the second flow channel plate. The first control valve is installed on the second flow channel plate and communicates with the flow channel in the second flow channel plate. The first control valve is used to control the flow channel switching between the second flow channel plate and the air conditioning heat exchanger assembly.

[0440] According to an embodiment of the present invention, the coolant-side module integrates the second flow channel plate, the water pump, and the first control valve, reducing the layout of wiring and piping, minimizing the space occupied by the coolant circulation loop, and lowering assembly difficulty. Furthermore, since the first control valve controls the flow channel switching between the second flow channel plate and the air conditioning heat exchanger assembly to regulate the temperature of the air conditioning heat exchanger assembly, the air conditioning heat exchanger assembly can switch between different modes. Therefore, the coolant-side module of the present invention integrates the second flow channel plate, the water pump, and the first control valve, saving layout space, improving assembly efficiency, simplifying electrical control complexity, and achieving cost reduction and efficiency improvement.

[0450] Another embodiment of the pipeline assembly of the present invention includes a plurality of pipe bodies extending along a first direction and arranged along a preset direction orthogonal to the first direction; a base to which the plurality of pipe bodies are connected, the base having a plurality of openings that are connected to the plurality of pipe bodies one by one, and both the pipe bodies and the base being made of soft material.

[0451] According to the embodiment of the present invention, since there are multiple pipes and each pipe is connected to the base, the multiple pipes can be integrated together to reduce the number of components to be assembled, which is beneficial to improving assembly efficiency. In addition, since both the pipes and the base are made of soft materials, they can be used for buffering and vibration reduction to reduce the vibration transmitted from the refrigerant side module to the coolant side module, resulting in good vibration reduction and noise reduction effects.

[0460] Optionally, the base includes a first base and a second base, with a first end of the tube connected to the first base and a second end of the tube connected to the second base.

[0461] A first control valve according to another embodiment of the present invention includes a valve body, the valve body including a valve shell and a valve core, the valve shell having a valve cavity, and the valve shell having a first port, a second port, a third port and a fourth port. The valve core is disposed in the valve cavity and is movable between a first position, a second position and a third position. In the first position, the third port is connected to the first port and the fourth port is connected to the second port; in the second position, the third port is connected to both the first port and the second port, and the fourth port is closed; in the third position, the fourth port is connected to both the first port and the second port, and the third port is closed.

The first air conditioning heat exchanger is arranged side by side on one side of the second air conditioning heat exchanger along a direction orthogonal to the thickness of the second air conditioning heat exchanger.

[0471] According to an embodiment of the present invention, the air conditioning heat exchanger assembly allows for the selective introduction of liquids at the same or different temperatures into the first and second air conditioning heat exchangers. This enables the first and second air conditioning heat exchangers to cool or heat simultaneously, or for one of them to cool while the other heats.
