[0004] Currently, the thermal management modules of mainstream hybrid vehicles adopt a distributed layout scheme, with complex pipeline connections between various components and the sealing between pipelines cannot be guaranteed.

[0024] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0025] The thermal management system of a hybrid vehicle is an important part of the overall vehicle system. It is used to coordinate the matching, optimization and control of related components and subsystems such as the vehicle engine, air conditioning, battery, and motor from the perspective of the whole vehicle. It effectively solves the thermal-related problems of the whole vehicle, keeps each functional module in the optimal temperature range, improves the vehicle's economy and power, and ensures safe driving.

[0026] Currently, the thermal management modules of mainstream hybrid vehicles adopt a distributed layout scheme, which results in complex pipeline connections between various components and compromises the sealing between pipelines. This not only affects heat exchange efficiency but also occupies a large amount of space.

[0027] To address the aforementioned technical issues, this application provides an integrated thermal management module and vehicle, which can reduce the connection pipelines of the thermal management module, reduce the space occupied by the thermal management module in the front compartment of the vehicle, and improve the space utilization of the entire vehicle.

[0028] like Figures 1 to 4 As shown, the integrated thermal management module provided in this application embodiment includes a kettle body 1, a flow channel assembly 2, a water pump 3, a cooler 4, and a water-to-water heat exchanger 5.

[0029] like Figure 5 and Figure 6 As shown, the kettle body 1 is divided into a battery-powered kettle 11 and a high-temperature kettle 12. The battery-powered kettle 11 is provided with a battery pack inlet 13.

[0030] Both the battery water tank 11 and the high-temperature water tank 12 contain coolant. The coolant in the battery water tank 11 can enter the battery pack circuit through the battery pack inlet 13 to cool or heat the battery pack.

[0031] The kettle body 1 has an internal vertical wall. The internal space of the kettle body 1 is divided into two parts by the vertical wall. One part works as a battery-powered kettle 11, and the other part works as a high-temperature kettle 12.

[0032] The high-temperature water tank 12 and the battery water tank 11 are used to maintain system pressure balance, regulate coolant volume changes, achieve gas-liquid separation, and provide liquid level monitoring to ensure efficient and stable operation of the engine and battery pack and prevent overheating damage.

[0033] like Figure 2 As shown, the top of the kettle body 1 is provided with two kettle spouts 18 and two kettle lids 14 covering the kettle spouts 18. One kettle spout 18 is connected to the high-temperature kettle 12, and the other kettle spout 18 is connected to the battery kettle 11. The two kettle spouts 18 are used to replenish coolant to the high-temperature kettle 12 and the battery kettle 11, respectively.

[0034] The flow channel assembly 2 is connected to the kettle body 1. The flow channel assembly 2 is constructed with a liquid flow channel 21, which is connected to the battery kettle 11 and the high temperature kettle 12 respectively. The flow channel assembly 2 is provided with a battery pack outlet 24 that is connected to the battery pack inlet 13.

[0035] like Figure 1 and Figure 2 As shown, the flow channel assembly 2 is located below the pot body 1, which can seal the bottom of the pot body 1, and the coolant in the pot body 1 can enter the liquid flow channel 21. The flow channel assembly 2 integrated with the pot body 1 has a simple structure, reduced heat loss, and improved heat exchange efficiency.

[0036] Optionally, the flow channel assembly 2 is welded to the kettle body 1 to reduce the assembly process and number of pipes in the expansion kettle.

[0037] The water pump 3, cooler 4 and water-to-water heat exchanger 5 are all installed on the flow channel assembly 2 and located on the side away from the kettle body 1. The cooler 4 and water-to-water heat exchanger 5 are both connected to the liquid flow channel 21, and the water pump 3 is connected to the battery kettle 11.

[0038] like Figure 2 As shown, the cooler 4 is provided with a refrigerant inlet 41 and a refrigerant outlet 42. The refrigerant inlet 41 and the refrigerant outlet 42 constitute the refrigerant circuit of the cooler 4. The refrigerant enters the cooler 4 through the refrigerant inlet 41 and flows out of the cooler 4 through the refrigerant outlet 42, ensuring the cooling and temperature reduction function of the cooler 4.

[0039] Cooler 4 cools the coolant in the integrated thermal management module through heat exchange, while water-to-water heat exchanger 5 heats the coolant in the integrated thermal management module through heat exchange. Water pump 3 increases the flow rate of the coolant in the integrated thermal management module. It is understood that the heat exchange functions of cooler 4 and water-to-water heat exchanger 5 can be opened or closed using components such as three-way valves. For example, by closing the refrigerant circuit of cooler 4 using valves, the refrigerant in the circuit stops flowing, and the heat exchange function of cooler 4 is shut off.

[0040] like Figures 1 to 4As shown, the water pump 3, cooler 4 and water-to-water heat exchanger 5 are located below the flow channel assembly 2. The bottom of the flow channel assembly 2 extends to form two supports 25, which are used to fix the integrated thermal management module to the vehicle body.

[0041] The integrated thermal management module provided in this application integrates the battery water tank 11 and the high-temperature water tank 12 into the same tank body 1, and uses the flow channel assembly 2 to replace the traditional pipelines, reducing the number of connecting pipelines, which is beneficial to improving heat exchange efficiency and reducing flow resistance, and reducing the space occupied by the thermal management module in the front compartment of the vehicle; in addition, by installing the water pump 3, cooler 4 and water-to-water heat exchanger 5 on the side of the flow channel assembly 2 away from the tank body 1, the space in the height direction of the thermal management module is fully utilized, which is beneficial to improving the space utilization rate of the whole vehicle.

[0042] In some embodiments, the flow channel assembly 2 includes an upper flow channel plate 22 and a lower flow channel plate 23 connected together. The upper flow channel plate 22 is located between the lower flow channel plate 23 and the kettle body 1. The upper flow channel plate 22 has a first through hole 221 and a second through hole 222. The first through hole 221 is used to connect the battery kettle 11 and the liquid flow channel 21, and the second through hole 222 is used to connect the battery kettle 11 and the water pump 3.

[0043] like Figure 2 , Figure 3 and Figure 9 As shown, the upper flow channel plate 22 is located on top of the lower flow channel plate 23, and the upper flow channel plate 22 and the lower flow channel plate 23 together form a liquid flow channel 21.

[0044] The upper flow channel plate 22 and the lower flow channel plate 23 can be connected by welding, threaded fasteners, snap-fit ​​connection, bonding and other methods, which simplifies the assembly process of the flow channel assembly 2, reduces the connection points of traditional pipelines, thereby reducing the risk of leakage and improving the sealing performance and heat exchange efficiency of the flow channel assembly 2.

[0045] The upper runner plate 22 and the lower runner plate 23 can be made of the same material, for example, both the upper runner plate 22 and the lower runner plate 23 are made of plastic.

[0046] Optionally, there may be multiple first through holes 221. Some of these first through holes 221 serve as outlets for the battery coolant reservoir 11, through which coolant flows from the reservoir 11 to the liquid flow channel 21. Other first through holes 221 serve as inlets for the reservoir 11, through which coolant flows from the liquid flow channel 21 to the reservoir 11. Of course, the number of first through holes 221 can also be single, for example... Figure 7 As shown, the first through hole 221 serves as the water inlet of the battery water tank 11, through which the coolant in the liquid flow channel 21 can enter the battery water tank 11.

[0047] Optionally, there may be multiple second through holes 222, some of which are connected to the inlet of the water pump 3, through which coolant in the battery reservoir 11 flows into the water pump 3, and other second through holes 222 are connected to the outlet of the water pump 3, through which coolant in the water pump 3 flows into the battery reservoir 11. For example Figure 7 As shown, there are two second through holes 222. The second through hole 222 located relatively higher is connected to the water inlet of the water pump 3, and the second through hole 222 located relatively lower is connected to the water outlet of the water pump 3.

[0048] Optionally, such as Figure 7 and Figure 9 As shown, the upper flow channel plate 22 is also provided with a third through hole 223, and the lower flow channel plate 23 is provided with a high-temperature water inlet 231 that communicates with the liquid flow channel 21. The third through hole 223 is used to connect the high-temperature water tank 12 and the high-temperature water inlet 231. The coolant in the high-temperature water tank 12 can flow to the high-temperature water inlet 231 through the third through hole 223, and further flow to the engine circuit through the high-temperature water inlet 231.

[0049] The first through hole 221, the second through hole 222 and the third through hole 223 are directly integrated on the upper flow channel plate 22, replacing the external water pipe, reducing the need for additional pipes, further improving sealing reliability, and reducing flow resistance and heat loss.

[0050] In some embodiments, such as Figure 10 As shown, the liquid flow channel 21 includes a first flow channel 211, a second flow channel 212 and a third flow channel 213. The first flow channel 211 is connected to the battery pack outlet 24 and the water-to-water heat exchanger 5, respectively. The second flow channel 212 is connected to the water-to-water heat exchanger 5 and the cooler 4, respectively. The third flow channel 213 is connected to the cooler 4 and the first through hole 221, respectively.

[0051] The integrated thermal management module has a first coolant circuit in which the coolant flows sequentially through the battery pack outlet 24, the first flow channel 211, the water-to-water heat exchanger 5, the second flow channel 212, the cooler 4, the third flow channel 213, the battery water tank 11, the second through hole 222, the water pump 3, the battery water tank 11, and the battery pack inlet 13.

[0052] The first coolant circuit is used to cool or heat the battery pack, preventing it from malfunctioning due to overheating or failing to function properly due to undercooling. Specifically, the coolant in the battery pack circuit enters the first coolant circuit through the battery pack outlet 24, undergoes heat exchange in the first coolant circuit, and then re-enters the battery pack circuit through the battery pack inlet 13, thereby using the coolant to cool or heat the battery pack.

[0053] The lower flow channel plate 23 is provided with a baffle for separating the flow channels. Under the action of the baffle, the first flow channel 211, the second flow channel 212 and the third flow channel 213 are separated from each other to avoid disturbing the coolant flow path of each other.

[0054] When the first coolant circuit is in cooling mode, the heat exchange function of the water-to-water heat exchanger 5 is turned off, and only the cooler 4 is used to cool the coolant; when the first coolant circuit is in heating mode, the heat exchange function of the cooler 4 is turned off, and only the water-to-water heat exchanger 5 is used to heat the coolant.

[0055] In this embodiment, the coolant undergoes heat exchange inside the flow channel assembly 2, shortening the coolant flow path, reducing additional pipes and joints, and simultaneously reducing coolant flow resistance and energy loss.

[0056] In some embodiments, such as Figure 10 As shown, the water-to-water heat exchanger 5 has a first inlet 5A, a first outlet 5B, a second inlet 5C, and a second outlet 5D. The first inlet 5A and the first outlet 5B are connected, and the second inlet 5C and the second outlet 5D are connected. The first inlet 5A is located at one end of the first flow channel 211, and the first outlet 5B is located at one end of the second flow channel 212.

[0057] like Figure 3 As shown, the kettle body 1 is provided with a heat exchanger inlet 15, and the lower flow channel plate 23 is provided with a heat exchanger outlet 232, as... Figure 10 As shown, the liquid flow channel 21 also includes a fourth flow channel 214 and a fifth flow channel 215. The fourth flow channel 214 is connected to the heat exchanger inlet 15 and the second inlet 5C, respectively. The fifth flow channel 215 is connected to the second outlet 5D and the heat exchanger outlet 232, respectively.

[0058] Optionally, such as Figure 7 As shown, the upper flow channel plate 22 is provided with a fourth through hole 224, which is used to connect the heat exchanger inlet 15 and the fourth flow channel 214. The fourth through hole 224 is located between the high temperature kettle 12 and the battery kettle 11.

[0059] The integrated thermal management module also has a second coolant circuit, in which the coolant flows sequentially through the heat exchanger inlet 15, the fourth flow channel 214, the second inlet 5C, the second outlet 5D, the fifth flow channel 215, and the heat exchanger outlet 232.

[0060] The water-to-water heat exchanger 5 has a first heat exchange channel and a second heat exchange channel. The first inlet 5A and the first outlet 5B are located at both ends of the first heat exchange channel, and the second inlet 5C and the second outlet 5D are located at both ends of the second heat exchange channel. The first heat exchange channel and the second heat exchange channel are separated from each other, and the coolant in the first heat exchange channel and the coolant in the second heat exchange channel can exchange heat.

[0061] The dual-channel design of the water-to-water heat exchanger 5 physically isolates the battery pack circuit from the engine cooling circuit, but allows for heat exchange, preventing coolant mixing. At the same time, it utilizes the engine's waste heat to heat the battery, improving energy utilization.

[0062] The heat exchanger inlet 15 is connected to the engine cooling circuit. The coolant with a higher temperature in the engine cooling circuit flows into the fourth flow channel 214 through the heat exchanger inlet 15, and then into the second heat exchange channel, where it exchanges heat with the coolant in the first heat exchange channel, thereby raising the temperature of the coolant in the first coolant circuit. Subsequently, the coolant in the second heat exchange channel flows to the heat exchanger outlet 232 through the fifth flow channel 215. The coolant flowing out of the heat exchanger outlet 232 has a lower temperature after heat exchange, and the coolant with a lower temperature flows back into the engine cooling circuit.

[0063] For example, when the first coolant circuit is in cooling mode, the second coolant circuit is closed by valve components. At this time, the coolant in the second coolant circuit does not flow, and the heat exchange function of the water-to-water heat exchanger 5 is turned off. Therefore, the water-to-water heat exchanger 5 does not heat the coolant. At this time, the coolant in the first coolant circuit is cooled only by the cooler 4. When the first coolant circuit is in heating mode, the coolant in the second coolant circuit flows, and the heat exchange function of the water-to-water heat exchanger 5 is turned on. The refrigerant circuit of the cooler 4 is closed by valve components. At this time, the refrigerant in the refrigerant circuit does not flow, and the heat exchange function of the cooler 4 is turned off. The water-to-water heat exchanger 5 heats the coolant in the first coolant circuit, while the coolant temperature in the second coolant circuit decreases and flows to the engine cooling circuit.

[0064] Optionally, the cooler 4 is provided with a cooler inlet 4A and a cooler outlet 4B. The first outlet 5B and the cooler inlet 4A are located at the two ends of the second flow channel 212, respectively, and the cooler outlet 4B is located at one end of the third flow channel 213.

[0065] In the first coolant circuit, the coolant flow path is as follows: battery pack outlet 24, first flow channel 211, first inlet 5A, first outlet 5B, second flow channel 212, cooler inlet 4A, cooler outlet 4B, third flow channel 213, first through hole 221, battery reservoir 11, second through hole 222 connected to the inlet of water pump 3, water pump 3, second through hole 222 connected to the outlet of water pump 3, battery reservoir 11, battery pack inlet 13.

[0066] In the second coolant circuit, the coolant flow path is: heat exchanger inlet 15, fourth flow channel 214, second inlet 5C, second outlet 5D, fifth flow channel 215, and heat exchanger outlet 232.

[0067] In some embodiments, the upper flow channel plate 22 has at least two spaced heat insulation baffles 225 protruding from the side facing the kettle body 1, and the heat insulation baffles 225 are located between the battery kettle 11 and the high-temperature kettle 12.

[0068] The side of the upper flow channel plate 22 facing the pot body 1, i.e. the upper side of the upper flow channel plate 22, has the heat insulation baffle 225 protruding outward relative to the upper surface of the upper flow channel plate 22.

[0069] like Figure 7 As shown, there are two heat insulation barriers 225, which are parallel to each other and spaced apart.

[0070] Optionally, insulation material can be filled between adjacent insulation walls 225 to enhance the insulation effect.

[0071] In this embodiment, by setting multiple heat insulation barriers 225, a double-layer heat insulation structure is formed, which reduces the heat conduction between the high-temperature kettle 12 and the battery kettle 11 and improves the stability of the integrated thermal management module.

[0072] In some embodiments, the upper flow channel plate 22 is provided with at least one bent baffle 226 protruding on the side facing the pot body 1, and the top end of the bent baffle 226 is bent and covers the top of the first through hole 221.

[0073] like Figure 7 As shown, the bending baffle 226 protrudes from the upper surface of the upper flow channel plate 22, and the upper end of the bending baffle 226 is bent in a direction that is approximately parallel to the surface of the upper flow channel plate 22, so that the bending baffle 226 is approximately "L" shaped.

[0074] A bent baffle 226 is disposed at the first through hole 221, which serves as the water inlet of the battery coolant reservoir 11. The bent baffle 226 is used to prevent the coolant from directly impacting the top of the reservoir when it flows into the battery coolant reservoir 11 from the liquid flow channel 21, which helps to reduce noise. At the same time, the bent structure of the bent baffle 226 helps to guide the coolant smoothly into the battery coolant reservoir 11.

[0075] In some embodiments, the upper flow channel plate 22 is provided with a baffle wall 227 protruding on the side facing the kettle body 1. The baffle wall 227 is disposed between the first through hole 221 and the second through hole 222, thereby dividing the area of ​​the upper flow channel plate 22 used to cooperate with the battery kettle 11 into a first channel 228 and a second channel 229. The baffle wall 227 is provided with a secondary baffle wall 2271 protruding on the side of the baffle wall 227 near the first channel 228.

[0076] like Figure 7 and Figure 8 As shown, the baffle 227 protrudes outward relative to the upper surface of the upper flow channel plate 22, and the first channel 228 and the second channel 229 divided by the baffle 227 are both flow paths for the coolant in the battery water tank 11 to flow to the inlet of the water pump 3.

[0077] Please refer to Figure 7 and Figure 8 ,in Figure 8 The arrows indicate the flow path of the coolant. Since the secondary baffle 2271 is located on the side of the turbulence baffle 227 close to the first channel 228, the flow path of the coolant in the first channel 228 is more rugged under the turbulence of the secondary baffle 2271, forming a maze-like first channel 228. This helps to extend the coolant path, promote gas separation, and enhance gas-liquid separation efficiency. The structure of the second channel 229 is simpler than that of the first channel 228, allowing the coolant to flow quickly through the second channel 229 to the second through hole 222, which serves as the water inlet of the water pump 3. In this way, both the degassing effect and the coolant flow speed are taken into account.

[0078] Optionally, such as Figure 5 As shown, the kettle body 1 is also provided with a first degassing port 16 and a second degassing port 17, both of which are connected to the high-temperature kettle 12 to allow gas to be released. Of course, the kettle body 1 may also be provided with a degassing port for connection to the battery-powered kettle 11.

[0079] In some embodiments, such as Figure 7 As shown, the upper flow channel plate 22 is also provided with a partition structure 2210. The partition structure 2210 is connected to the inner wall of the first through hole 221 and the bending baffle 226 respectively. The partition structure 2210 divides the first through hole 221 into a first sub-hole 2211 and a second sub-hole 2212. The first sub-hole 2211 is connected to the first channel 228, and the second sub-hole 2212 is connected to the second channel 229.

[0080] like Figure 7 As shown, the partition structure 2210 is located below the bent baffle 226 and is connected to the lower surface of the top bent structure of the bent baffle 226.

[0081] The partition structure 2210 enables the diversion of coolant. The first sub-hole 2211 can be used for coolant degassing, and the second sub-hole 2212 can be used for rapid coolant circulation, without the need for additional valves for diversion. At the same time, the partition structure 2210 strengthens the bending baffle 226, preventing it from deforming or being damaged by the impact of the coolant.

[0082] In some embodiments, such as Figure 2 and Figure 4 As shown, the integrated thermal management module also includes a PT sensor 6 and an electronic expansion valve 7, which are installed on the cooler 4 and are both located on the side of the flow channel assembly 2 away from the pot body 1.

[0083] Electronic Expansion Valve 7 (EXV) is an electronically controlled throttling device connected to cooler 4. Electronic Expansion Valve 7 is used to dynamically adjust the opening degree according to system requirements to ensure that the refrigerant flow matches the load.

[0084] PT sensor 6 is a temperature and pressure sensor used to detect the pressure of the refrigerant in cooler 4.

[0085] In this embodiment, the seven thermal management components—high-temperature water tank 12, battery water tank 11, cooler 4, electronic expansion valve 7, PT sensor 6, water pump 3, and water-to-water heat exchanger 5—are integrated into one unit. The internal flow channel structure design replaces the pipelines, reducing the absolute volume of the integrated thermal management module. The routing of each pipeline is smooth and aesthetically pleasing, reducing assembly steps, improving heat exchange efficiency and reducing flow resistance, enhancing exhaust effect, and alleviating the layout pressure of the entire vehicle.

[0086] This application also provides a vehicle that includes the integrated thermal management module provided in any of the above embodiments.

[0087] The vehicle provided in this application embodiment has the beneficial effects of the integrated thermal management module of any of the above embodiments because it includes the integrated thermal management module of any of the above embodiments, which will not be repeated here.
