Modes for Carrying Out the Invention

[0036] Hereinafter, with reference to the accompanying drawings, exemplary embodiments of the present disclosure will be described in more detail. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, the present disclosure can be implemented in various ways and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to enable those skilled in the art to fully convey the scope of the present disclosure.

[0037] Among the existing thermal management systems for the entire vehicle, the thermal management components adopt a decentralized layout, and the following problems exist. (1) The lengths of the cooling pipeline and the air-conditioning pipeline increase, resulting in an increase in the flow resistance of the system, and it is necessary to adopt a high-power water pump to meet the system requirements. (2) The increase in the lengths of the cooling pipeline and the air-conditioning pipeline also leads to an increase in the heat leakage value of the system, and it is necessary to extend the PTC heating time or increase the PTC heating power to meet the heating demand of the system. (3) Thermal management components such as the expansion water tank, motor water pump assembly, battery water pump assembly, heat exchanger, water condenser, water temperature sensor, four-way solenoid valve, three-way solenoid valve, two-way proportional valve, air-conditioning electronic expansion valve, and air-conditioning pipeline adopt a decentralized layout and are connected through the cooling pipeline and the air-conditioning pipeline, making the required layout space complex. (4) The above-mentioned thermal management components are supplied by different suppliers and assembled at the base, resulting in a long working hours and being disadvantageous to the management of the suppliers. (5) It is necessary to adopt a large number of cooling pipelines and air-conditioning pipelines, resulting in an increase in the cost and weight of the entire vehicle. Therefore, from the perspectives of cost savings, weight reduction, layout space, etc., an integrated multi-channel cooling connection pipeline that can be used to integrally arrange the thermal management components is urgently needed.

[0038] To solve or at least partially solve the above problems, embodiments of the present invention propose a multi-channel cooling pipeline integration device. FIG. 1 is a schematic diagram showing the configuration of a multi-channel cooling pipeline integration device 110 according to an embodiment of the present invention as viewed from one side thereof, and FIG. 2 is a schematic diagram showing the configuration of the multi-channel cooling pipeline integration device 110 shown in FIG. 1 as viewed from the other side thereof. With reference to FIGS. 1 and 2, the multi-channel cooling pipeline integration device 110 is substantially rectangular plate-shaped, and a plurality of cooling connection pipelines 111 are formed inside thereof, and a plurality of member attachment points and a plurality of member connection ports 116 are installed on its surface. The plurality of member attachment points are arranged to attach at least two heat management members thereon. Each member connection port 116 communicates with a corresponding cooling connection pipeline 111 such that the at least two heat management members attached to the plurality of member attachment points are connected to the corresponding cooling connection pipelines through the member connection ports 116, and the at least two heat management members realize the connection between each other through the plurality of cooling connection pipelines 111.

[0039] In the multi-channel cooling pipeline integration device 110 of the embodiment of the present invention, since a plurality of cooling connection pipelines 111 are formed inside and a plurality of member attachment points and a plurality of member connection ports 116 are installed on its surface, the multi-channel cooling pipeline integration device 110 not only functions as a connection path between different heat management members, but also functions as a carrier for these heat management members, integrates the heat management members to realize the connection between each other, eliminates the need to use a large number of cooling rubber tubes and nylon tubes for connection, saves the cost and layout space of the heat management system, and can reduce the weight of the entire vehicle.

[0040] In application, the cooling connection pipelines 111 inside the multi-channel cooling pipeline integration device 110 are designed based on the connection methods of the respective heat management members in the heat management principle diagram of the entire vehicle to be actually applied, thereby realizing the connection of pipelines (such as water pipelines) between the heat management members. Generally, the installation directions of the respective cooling connection pipelines 111 within the multi-channel cooling pipeline integration device 110 extend substantially along the longitudinal direction of the multi-channel cooling pipeline integration device 110. During use, by installing the multi-channel cooling pipeline integration device 110 such that its longitudinal direction is substantially parallel to the horizontal direction and its width direction is substantially perpendicular to the vehicle chassis, the flow resistance due to the gravitational action of the coolant (such as water) flowing through each cooling connection pipeline 111 can be minimized as much as possible.

[0041] The member mounting points on the multi-channel cooling pipeline integration device 110 can be selected according to the heat management members actually required for the heat management of the entire vehicle, and their positions can be installed according to the outer shape, dimensions of the actually required heat management members, and the connection and operation methods in the heat management principle diagram of the entire vehicle, etc., so that these heat management members can be rationally integrated and arranged spatially on the multi-channel cooling pipeline integration device 110. The member connection ports 116 can be correspondingly installed based on the member mounting points, so that the heat management members integrated and arranged on the multi-channel cooling pipeline integration device 110 through these member mounting points can be connected through these member connection ports 116 via the cooling connection pipelines 111 inside the multi-channel cooling pipeline integration device 110.

[0042] Generally, the member mounting points on the multi-channel cooling pipeline integration device 110 can include at least two of the expansion tank mounting point, multi-way valve mounting point 1102, water pump mounting point 1103, heat exchanger mounting point 1104, condenser mounting point 1105, temperature sensor mounting point 1106, two-way proportional valve mounting point 1107, etc., and at least two of the expansion tank, multi-way valve 130, water pump 140, heat exchanger 150, condenser 160 (such as a water-cooled condenser), temperature sensor 170, two-way proportional valve 192, etc. can be correspondingly integrated into the multi-channel cooling pipeline integration device 110.

[0043] In some embodiments, the member attachment points include the water pump attachment points 1103. At this time, the plurality of water pump attachment points 1103 are installed on one side of one end in the longitudinal direction of the multi-channel cooling pipeline integration device 110. Due to the position distribution of the plurality of water pump attachment points 1103, at least two water pumps 140 are attached to the same side of one end in the longitudinal direction of the multi-channel cooling pipeline integration device 110 via the plurality of water pump attachment points 1103 and are arranged along the width direction of the multi-channel cooling pipeline integration device 110. Such an arrangement of the water pump attachment points 1103 is advantageous for the attachment management of the water pump 140 and can make more effective use of the installation space on the multi-channel cooling pipeline integration device 110. In a specific embodiment, for a water pump with a cylindrical pump casing, as shown in FIG. 1, the water pump attachment points 1103 of this water pump are a plurality of first fixing blocks that are evenly distributed on the outer periphery of the annular first fixing member on the multi-channel cooling pipeline integration device 110 and protrude in the circumferential direction. A first through hole is formed in each first fixing block. At one end of the water pump casing of the water pump, a second fixing member corresponding to the first fixing member is correspondingly installed. On the outer periphery of the second fixing member, second fixing blocks corresponding to the first fixing blocks are installed. A second through hole corresponding to the first through hole is formed in each second fixing block. During installation, a fastener (such as a bolt) is used to pass through the corresponding second through hole and the first through hole to fix and attach the water pump 140 to the multi-channel cooling pipeline integration device 110. By installing the member connection port 116 corresponding to the water pump 140 at the center of the corresponding first fixing member, the connection between the water pump 140 and the cooling connection pipeline 111 is realized. In a more specific embodiment, the water pump attachment points 1103 can include a motor water pump attachment point 1103 for attaching a motor water pump and a battery water pump attachment point 1103 for attaching a battery water pump.The motor water pump mounting point 1103 is located below the battery water pump mounting point 1103 (here, below means below under the usage state of the multi-channel cooling pipeline integration device 110). The motor water pump refers to a water pump arranged to drive the flow of the coolant in the motor cooling circuit of the vehicle, and the battery water pump refers to a water pump arranged to drive the flow of the coolant in the battery pack cooling circuit of the vehicle.

[0044] In some embodiments, the member mounting point can further include an expansion water tank mounting point. The expansion water tank mounting point is installed on the other side of one end where the water pump mounting point 1103 in the multi-channel cooling pipeline integration device 110 is located, so that the expansion water tank can be mounted at a position on the other side facing the water pump 140 in the multi-channel cooling pipeline integration device 110. Since the expansion water tank has a large volume and is usually connected to one of the water pumps 140, by arranging it in this way, the length of the cooling connection pipeline 111 (connection passage) between the expansion water tank and the water pump 140 can be made as short as possible, the flow resistance can be reduced, and the installation space on the multi-channel cooling pipeline integration device 110 can be utilized more effectively, and the arrangement space can be saved. In some other embodiments, considering that the volume of the expansion water tank is relatively large, the method of mounting using the mounting point is difficult to guarantee its firmness. Since the material of the expansion water tank is close to the material of the cooling connection pipeline 111, a method of integrally forming the expansion water tank and the multi-channel cooling pipeline integration device 110 can be adopted, which will be described later. Although the position of the expansion water tank mounting point is not shown in the drawings, those skilled in the art should be able to install an appropriate expansion water tank mounting point on the multi-channel cooling pipeline integration device 110 so that the expansion water tank can be mounted at a position on the other side facing the water pump 140 in the multi-channel cooling pipeline integration device 110 after reading this application.

[0045] In some embodiments, the member mounting point can include the multi-way valve mounting point 1102. According to the overall vehicle thermal management principle diagram, the ports of the multi-way valve are connected to a plurality of thermal management members in the overall vehicle thermal management system to control the on / off of different thermal management circuits. Thus, the multi-way valve mounting point 1102 can be installed at the middle part on one side of the multi-channel cooling pipeline integration device 110 so that the multi-way valve 130 can be installed at the middle part on one side of the multi-channel cooling pipeline integration device 110, facilitating the connection between the multi-way valve 130 and other thermal management members. The multi-way valve 130 can be a four-way solenoid valve, a three-way solenoid valve, etc. Preferably, the multi-way valve 130 is a nine-way valve, which can replace one normal three-way solenoid valve and two four-way solenoid valves in the overall vehicle thermal management system to achieve nine passages, thereby further reducing the overall vehicle cost and weight. More preferably, the multi-way valve 130 can be an integrated nine-way valve. For the integrated nine-way valve, a flat mounting panel is formed on the multi-channel cooling pipeline integration device 110, and nine passage connection ports (i.e., the member connection ports 116 of the integrated nine-way valve) for connecting to the nine passages of the integrated nine-way valve are intensively arranged on this mounting panel to realize the unification of the connection port positions. By adopting the member connection ports 116 intensively arranged on the flat mounting panel and the corresponding multi-way valve mounting point 1102, the installation of the integrated nine-way valve can be facilitated, the arrangement space occupied by the multi-way valve 130 can be made smaller, and the arrangement space and distribution aesthetics of the cooling connection pipeline 111 communicated with these member connection ports 116 can be significantly improved.

[0046] In some embodiments, the member attachment point can further include a heat exchanger attachment point 1104. Since the heat exchanger attachment point 1104 is installed on the same side as the multi-way valve attachment point 1102 in the multi-channel cooling pipeline integration device 110, and due to the position distribution of the heat exchanger attachment point 1104, the heat exchanger 150 can be attached to the same side and adjacent position as the multi-way valve 130 in the multi-channel cooling pipeline integration device 110, the connection pipeline length between the heat exchanger 150 and the ports of the multi-way valve 130 can be effectively shortened. In a specific embodiment, the multi-way valve attachment point 1102 may be installed on the upper side of the middle part of the multi-channel cooling pipeline integration device 110 (where the upper side here means the upper side in the vertical direction in the usage state of the multi-channel cooling pipeline integration device 110), and the heat exchanger attachment point 1104 may be installed on the lower side of the middle part, as specifically shown in FIG. 1.

[0047] In some embodiments, the member attachment points may further include a condenser attachment point 1105. The condenser attachment point 1105 is installed at one longitudinal end on the same side as the heat exchanger attachment point 1104 in the multi-channel cooling pipeline integration device 110. Due to the position distribution of the condenser attachment point 1105, the condenser 160 can be attached at a position adjacent to and on the same side as the heat exchanger 150 in the multi-channel cooling pipeline integration device 110. Since the volume of the condenser in the overall vehicle thermal management system is generally large, by installing the condenser attachment point 1105 at one longitudinal end of the multi-channel cooling pipeline integration device 110, the condenser 160 can be installed at one longitudinal end of the multi-channel cooling pipeline integration device 110, ensuring that the condenser 160 has sufficient placement space. Also, by arranging the condenser 160 and the heat exchanger 150 on the same side of the multi-channel cooling pipeline integration device 110 and adjacent to the heat exchanger 150, the utilization rate of the attachment space can be improved. Of course, when the member attachment points simultaneously include an expansion tank attachment point and the condenser attachment point 1105, by arranging the expansion tank attachment point and the condenser attachment point 1105 at both longitudinal ends of the multi-channel cooling pipeline integration device 110 respectively, the expansion tank 120 and the condenser 160 can be attached to both longitudinal ends of the multi-channel cooling pipeline integration device 110 respectively, and it is understood by those skilled in the art that sufficient placement space for each can be ensured.

[0048] In some embodiments, the member attachment points may further include a temperature sensor attachment point 1106. The temperature sensor attachment point 1106 is installed at a position corresponding to the designated cooling connection pipeline 111, and the temperature sensor 170 attached to this temperature sensor attachment point 1106 can measure the temperature of the coolant (such as water) in the designated cooling connection pipeline 111. The number and position of the temperature sensor attachment points 1106 can be installed according to the actual required overall vehicle thermal management principle diagram. For example, four temperature sensor attachment points 1106 for attaching four temperature sensors 170 respectively can be provided.

[0049] In some embodiments, the member mounting points may further include a two-way proportional valve mounting point 1107, which is installed at a position corresponding to a cooling connection pipeline 111 for connecting one of the water pumps 140 and the condenser 160. In this way, the two-way proportional valve 192 (for example, an intelligent two-way proportional valve) mounted thereon can control the flow of the coolant between the water pump 140 and the condenser 160.

[0050] Of course, for heat management members with relatively large volume or weight, in order to ensure the firmness of the installation, there may be multiple member mounting points corresponding to each heat management member. The number of member mounting points should ensure the stable installation of the heat management member. Those skilled in the art will understand that the present invention is not particularly limited in this regard.

[0051] For the heat management members that need to be integrated in the embodiments of the present invention, by reasonably distributing the member mounting points corresponding to these heat management members (specifically, including the expansion tank mounting point, multi-way valve mounting point 1102, water pump mounting point 1103, heat exchanger mounting point 1104, condenser mounting point 1105, temperature sensor mounting point 1106, two-way proportional valve mounting point 1107, etc.) on the multi-channel cooling pipeline integration device 110, the arrangement of the integrated heat management members can be made more compact, and the distribution of the cooling connection pipelines 111 in the multi-channel cooling pipeline integration device 110 can be optimized, reducing the manufacturing difficulty.

[0052] In some embodiments, as shown in FIG. 1, the multi-channel cooling pipeline integration device 110 is further provided with a plurality of external connection ports for cooling pipelines. These external connection ports for cooling pipelines are arranged to connect to the coolant connection pipelines of the vehicle components to be thermally managed, and the positions of the external connection ports for cooling pipelines are arranged according to the arrangement positions of the components to be thermally managed so that the coolant connection pipelines of the components to be thermally managed are the shortest. The components to be thermally managed here include, but are not limited to, a DC-DC converter, a high voltage coolant heater (HVCH), an on-board charger (OBC), a battery pack, a radiator, etc.

[0053] Considering the multi-channel cooling pipeline integration device 110 and the heat pipeline member to be integrated thereon as a whole, the corresponding components to be thermally managed (for example, the aforementioned DC-DC converter, HVCH, OBC, battery pack, radiator, etc.) can be regarded as the mating members of the multi-channel cooling pipeline integration device 110 and the integrated thermal management members. By fully considering the arrangement positions of the mating members, the positions of the external connection ports for cooling pipelines are uniformly installed to minimize the connection pipelines of the components to be thermally managed, thereby further reducing the cost and weight of the entire vehicle.

[0054] Specifically, the external connection ports of the cooling pipeline include the radiator liquid supply connection port 1108, the radiator liquid discharge connection port 1109, the DC-DC converter liquid supply connection port 1110, the high-pressure liquid heater liquid supply connection port 1111, the high-pressure liquid heater liquid discharge connection port 1114, the in-vehicle charger liquid discharge connection port 1112, the battery pack liquid supply connection port 1115, and the battery pack liquid discharge connection port 1113. The radiator liquid supply connection port 1108, the radiator liquid discharge connection port 1109, and the DC-DC converter liquid supply connection port 1110 are located at one end in the longitudinal direction of the multi-channel cooling pipeline integration device 110 (specifically, the end where the water pump mounting point 1103 is located). The radiator liquid supply connection port 1108 and the radiator liquid discharge connection port 1109 extend out to one side of the multi-channel cooling pipeline integration device 110 (specifically, the end where the water pump mounting point 1103 is located). The high-pressure liquid heater liquid supply connection port 1111, the in-vehicle charger liquid discharge connection port 1112, the battery pack liquid discharge connection port 1113, the high-pressure liquid heater liquid discharge connection port 1114, and the battery pack liquid supply connection port 1115 are located at the other end in the longitudinal direction of the multi-channel cooling pipeline integration device 110 (specifically, the other end where the condenser mounting point 1105 is located), are sequentially arranged along the width direction of the multi-channel cooling pipeline integration device 110, and their extending directions are the same as the extending direction of the radiator liquid supply connection port 1108. By setting it in this way, it is possible to achieve both space utilization, aesthetics, and ease of use of the connection ports.

[0055] In some embodiments, continuing to refer to FIG. 1, the multi-channel cooling pipeline integration device 110 is further provided with a plurality of mounting ears 115, which are arranged to attach and fix the multi-channel cooling pipeline integration device 110 to the vehicle body. Each mounting ear 115 protrudes outward from the edge of the multi-channel cooling pipeline integration device 110, and each mounting ear 115 has a through-hole (which can be called the third through-hole 1151), and is arranged to attach the multi-channel cooling pipeline integration device 110 to the vehicle body by cooperating with a fastener. Specifically, each mounting ear 115 includes a root portion connected to the edge of the multi-channel cooling pipeline integration device 110 and a head portion away from the multi-channel cooling pipeline integration device 110, and the head portion has a third through-hole 1151 which is a central through-hole. To ensure the firmness of the attachment, the number of mounting ears 115 is at least three, preferably three, and the three mounting ears are respectively installed on three edges forming a substantially rectangular contour of the multi-channel cooling pipeline integration device 110. Further, a ring-shaped cushion pad can be further installed in the third through-hole 1151 of each mounting ear 115. The thickness of the cushion pad is greater than the thickness of the head portion of the mounting ear 115, and the surface of the cushion pad protrudes from the third through-hole 1151. After the multi-channel cooling pipeline integration device 110 is attached and fixed to the vehicle body, the cushion pad can buffer the collision between the mounting ear 115 and the vehicle body part to which it is fixed. The cushion pad may be made of rubber.

[0056] In order to facilitate the molding of the multi-channel cooling pipeline integration device 110, a split molding method can be adopted. Referring to what is shown in FIG. 3, the multi-channel cooling pipeline integration device 110 can include a main body part 112, a first cover plate part 113, and a second cover plate part 114. The main body part 112, the first cover plate part 113, and the second cover plate part 114 are sequentially assembled along the thickness direction of the multi-channel cooling pipeline integration device 110. In the main body part 112, a first set of cooling connection pipelines 111a that open toward the first cover plate part 113 are formed. The first cover plate part 113 at least covers a part of the main body part 112 to seal the first set of cooling connection pipelines 111a, and in the first cover plate part 113, a second set of cooling connection pipelines 111b that open toward the second cover plate part 114 are formed. The second cover plate part 114 at least covers a part of the first cover plate part 113 to seal the second set of cooling connection pipelines 111b. By adopting such a configuration, a double-layer multi-channel cooling connection pipeline structure can be formed inside the multi-channel cooling pipeline integration device 110, making the structure of the multi-channel cooling pipeline integration device 110 more compact, reducing its planar occupation area, and making the distribution of the cooling connection pipelines 111 inside the multi-channel cooling pipeline integration device 110 more flexible.

[0057] In order to ensure heat insulation between each cooling connection pipeline 111 and reduce heat loss, the multi-channel cooling pipeline integration device 110 can adopt heat-insulating plastics such as PP (Polypropylene) or PA66 (Polyamide 66). By adopting the PP or PA66 material, while ensuring heat insulation, the strength of the multi-channel cooling pipeline integration device 110 can be ensured, and the structural stability and durability of the multi-channel cooling pipeline integration device 110 can be improved.

[0058] In some embodiments, the main body portion 112, the first cover plate portion 113, and the second cover plate portion 114 may be separately formed by injection molding. Then, the main body portion 112, the first cover plate portion 113, and the second cover plate portion 114 are connected and fixed by welding to obtain the multi-channel cooling pipeline integration device 110. The welding methods include, but are not limited to, hot plate welding, friction welding, laser welding, etc.

[0059] In some embodiments, in order to ensure the firmness of the installation of the expansion water tank and simplify the installation work, the tank body 120 of the expansion water tank can be fixed and integrated with the multi-channel cooling pipeline integration device 110 in advance. As shown in FIG. 3, the tank body 120 of the expansion water tank is composed of a tank body main body 120a and a tank body side cover 120b. The tank body main body 120a and the second cover plate portion 114 are integrally formed by injection, and after the tank body side cover 120b is injection molded separately, the tank body main body 120a and the tank body side cover 120b are connected and fixed by welding to form the entire tank body 120 of the expansion water tank. Here, the welding methods include, but are not limited to, hot plate welding, friction welding, laser welding, etc. A pressure lid attachment location is provided at the top of the tank body 120 of the expansion water tank. When the pressure lid 121 is attached, a complete expansion water tank can be obtained.

Referring to what is shown in FIGS. 4 and 5, the thermal management integrated module 100 generally can include one multi-channel cooling pipeline integrated device 110 among any of the above embodiments and combinations of embodiments, and at least two thermal management members. In the multi-channel cooling pipeline integrated device 110, a plurality of cooling connection pipelines 111 (for example, water channels) are formed, and a plurality of member attachment points and member connection ports 116 are provided. Therefore, it can function not only as a connection passage between different thermal management members, but also as a carrier of the entire thermal management integrated module 100 to carry the thermal management members. The at least two thermal management members are attached to the multi-channel cooling pipeline integrated device 110, and the connection between them is realized through the cooling connection pipelines in the multi-channel cooling pipeline integrated device 110.

[0062] In some embodiments, the thermal management members integrated in the multi-channel cooling pipeline integrated device 110 in the thermal management integrated module 100 may further include members in the refrigerant circulation circuit of vehicle air conditioners, such as a dryer, an electronic expansion valve 191, and an air conditioning pipeline 190.

[0063] In one embodiment, the thermal management integrated module 100 includes a dryer, two electronic expansion valves 191, and an air-conditioning pipeline 190. The dryer and the electronic expansion valves 191 are attached corresponding to positions on the other side facing the heat exchanger 150 of the multi-channel cooling pipeline integrated device 110. The air-conditioning pipeline 190 is a refrigerant circulation pipeline connected to the dryer, the electronic expansion valves 191, the heat exchanger 150, and the condenser 160 so as to realize the circulation of the refrigerant of the air-conditioning compressor. The main body of the air-conditioning pipeline 190 extends on one side of the multi-channel cooling pipeline integrated device 110 where the dryer is located.

[0064] Furthermore, an external connection port of the air-conditioning pipeline is installed on the air-conditioning pipeline 190 and arranged to be connected to a refrigerant connection pipeline of a heat management target related to vehicle air-conditioning. Specifically, the heat management targets related to vehicle air-conditioning include the built-in condenser and compressor of the air-conditioning unit. The external connection port of the air-conditioning pipeline includes an inlet connection port 193 for the built-in condenser, an outlet connection port 194 for the built-in condenser, an inlet connection port 195 for the compressor, and an outlet connection port 196 for the compressor. The inlet connection port 193 for the built-in condenser and the outlet connection port 194 for the built-in condenser are respectively arranged to be connected to the refrigerant connection pipelines of the built-in condenser of the vehicle air-conditioning unit. The inlet connection port 195 for the compressor and the outlet connection port 196 for the compressor are respectively arranged to be connected to the refrigerant connection pipelines of the vehicle compressor. In order to minimize the refrigerant connection pipelines of the built-in condenser and the compressor, the positions of the inlet connection port 193 for the built-in condenser, the outlet connection port 194 for the built-in condenser, the inlet connection port 195 for the compressor, and the outlet connection port 196 for the compressor are distributed according to the arrangement positions of the built-in condenser and the compressor. The external connection port of the air-conditioning pipeline can also include an inlet connection port for the built-in evaporator arranged to be connected to the refrigerant connection pipeline of the built-in evaporator of the air-conditioning unit. In order to minimize the refrigerant connection pipeline of the built-in evaporator, the position of the inlet connection port for the built-in evaporator is distributed according to the arrangement position of the built-in evaporator.

[0065] In another embodiment, the thermal management integration module 100 includes one electronic expansion valve 191 and an air-conditioning pipeline 190, and does not include a dryer bottle. At this time, as shown in FIGS. 4 and 5, the electronic expansion valve 191 is mounted corresponding to a position on the same side as the heat exchanger 150 of the multi-channel cooling pipeline integration device 110 and adjacent to the heat exchanger 150. The air-conditioning pipeline 190 is connected to the electronic expansion valve 191, the heat exchanger 150, and the condenser 160. The main body portion of the air-conditioning pipeline 190 extends on one side of the multi-channel cooling pipeline integration device 110 where the expansion water tank is located, forms a compressor outlet connection port 196 located below the expansion water tank on the same side as the expansion water tank. The built-in condenser outlet connection port 194 is formed on the valve seat of the electronic expansion valve 191. The built-in condenser inlet connection port 193 and the compressor inlet connection port 195 are respectively formed on the condenser 160 and the heat exchanger 150. Thereby, the length of the air-conditioning pipeline 190 and the length of the connection pipeline between these connection ports corresponding to the compressor and the built-in condenser can be effectively shortened.
