Technical Field

[0001] This application relates to the field of thermal management technology, such as thermal management technology for automotive, commercial, residential or energy storage applications, and particularly to a thermal management module. Background Technology

[0002] With the increasing integration of thermal management components and the intensifying cost competition among products, the application of thermal management component flow channels is becoming more widespread. At the same time, lower-cost and lighter flow channels have become a key focus for related technical teams.

[0003] In related technologies, thermal management components such as valves and heat exchangers on the agent side are integrated into the agent side flow channel plate. The agent side flow channel plate is made of aluminum alloy and is formed by extrusion, casting or forging. Water valves, pumps, kettles and other water-side components are integrated into the water side flow channel plate. The agent side flow channel plate and the water side flow channel plate are then fixedly connected. This structure is relatively complex and increases the difficulty of manufacturing. Summary of the Invention

[0004] The purpose of this invention is to provide a thermal management module with a relatively simple structure, which is beneficial to simplifying the manufacturing process.

[0005] The thermal management module provided by this application includes a substrate, thermal management components, and fluid control elements. The substrate includes a flow channel portion, the flow channel portion having a flow path, and the opening of the fluid control element communicating with a portion of the flow path. The fluid control element includes at least one of a water valve and a pump. The thermal management components include at least one of a valve module, a heat exchanger, and a liquid reservoir. The connecting pipe assembly communicates with at least two of the thermal management components. The substrate includes at least two mounting portions, and the at least two mounting portions are fixedly connected to the corresponding thermal management components. The mounting portions are located at the same end of the substrate.

[0006] The technical solution of this application includes a substrate and a fluid control element. The substrate has a flow channel, and the fluid control element communicates with the flow channel. It also includes a thermal management component, which is fixedly connected to the substrate. The thermal management component includes at least one of a valve module, a heat exchanger, and a liquid receiver. The thermal management components are integrated on the substrate and connected to each other through a pipe assembly. This eliminates the need for a large and heavy flow channel plate on the refrigerant side, resulting in a relatively simple structure and reduced weight of the thermal management module.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and specific technical solutions. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings; the terms "bottom surface" and "top surface," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0032] It should be understood that although various terms such as "first," "second," "third," and "fourth" may be used to describe different information in this application, such information should not be limited to these descriptions. These terms are only used to distinguish information of the same type from one another. Where there is no conflict, the various technical solutions in this application can complement each other.

[0033] The thermal management module implementation of the technical solution of the present invention can be applied to a vehicle thermal management system, and at least one implementation can be applied to other thermal management systems such as a household thermal management system or a commercial thermal management system. The following description takes a vehicle thermal management device as an example and is illustrated with reference to the accompanying drawings.

[0034] refer to Figure 1-22As shown, the present technical solution provides a thermal management module, including a substrate 1 and at least two valve modules 21. At least a portion of the substrate 1 is made of plastic. The valve modules 21 are fixedly connected to the substrate 1. The fixed connection includes welding, threaded connection, bonding, or a combination of two or more of the above. The valve module 21 includes a valve body 211 and a valve component 215. The valve body 211 includes a valve cavity 2111. At least a portion of the valve component 215 is located in the valve cavity 2111. The valve body 211 has a refrigerant passage 2112 and an external interface. One end of the refrigerant passage 2112 is connected to the valve cavity 2111, and the other end of the refrigerant passage 2112 is connected to the external interface. The external interface of the valve module 21 is connected to other thermal management elements through a connecting pipe, and / or a portion of the external interface of one valve module 21 is connected to the external interface of another valve module 21 through a connecting pipe. Specifically, valve module 21 includes valve body 211, valve body 211 has valve cavity 2111, at least part of valve component 215 is located in valve cavity 2111, valve body 211 has refrigerant passage 2112 and external interface, valve component 215 is used to control the opening, switching or adjustment of flow path, so for different systems, valve component 215 can be electronic expansion valve for adjusting flow, solenoid valve for controlling valve port opening and closing, and check valve, etc. One end of the refrigerant passage 2112 of the valve body 211 is connected to the valve cavity 2111, and the other end of the refrigerant passage 2112 is connected to the external interface. It should be noted that the connection between one end of the refrigerant passage 2112 and the valve cavity 2111 refers to the state in which the valve component 215 is not installed in the valve body 211. When the valve component 215 is installed in the valve body 211, the refrigerant passage 2112 upstream of the valve component 215 is connected to the valve cavity 2111. Whether the refrigerant passage 2112 downstream of the valve component 215 is connected to the valve cavity 2111 is determined by the opening and closing of the control valve component 215. That is, the valve component 215 controls the opening and closing or the degree of opening of the refrigerant passage 2112 upstream and downstream of the valve component 215. In this application, the external interface of the valve module 21 is connected to other thermal management components 2 through the pipe assembly 4. Other thermal management components 2 include heat exchangers 22, liquid receivers 23, compressors, sensors, etc. Here, heat exchangers 22 refers to heat exchangers in a broad sense. Depending on their role in the system, they can be condensers, evaporators, battery heat exchangers, direct cooling plates, etc. The liquid receiver 23 in this application is used to store refrigerant in the thermal management system, providing the liquid supply required for the refrigeration system cycle and ensuring the stable operation of the system. The liquid receiver 23 can be arranged between the condenser and the evaporator, that is, downstream of the condenser and upstream of the evaporator; or the liquid receiver 23 can be arranged downstream of the evaporator, that is, downstream of the evaporator and between the compressor, and has the function of gas-liquid separation to prevent liquid refrigerant from causing liquid slugging on the compressor.In other technical solutions, based on the requirements of the thermal management system and design, some valve modules 21 are connected to the external interfaces of the modules via pipes. In related technologies, multiple valve components 215 are integrated in the flow channel plate on the agent side. The flow channel plate is provided with valve chambers and flow channels. Each valve component is connected through the flow channels in the flow channel plate, and / or the valve components are connected to other thermal management components, such as heat exchangers, liquid receivers, etc., through the flow channels in the flow channel plate. The structure of the flow channel plate is complex, and the flow channels are relatively numerous and long, so the flow channel plate is relatively heavy and has a large volume. In this technical solution, the valve body 211 includes an external interface and a refrigerant channel 2112. The refrigerant channel 2112 is connected to the external interface. Valve components 215 are connected to each other via connecting pipes. The valve components 215 are connected to other thermal management components 2, such as heat exchangers 22 and liquid receivers 23, through connecting pipes. This relatively reduces the number and length of flow channels 101 in the valve body 211, thus reducing the weight and volume of the valve body 211. Compared to flow channel 101 plates in related technologies, the structure of the valve body 211 is relatively simple, lightweight, and small in size. Furthermore, the valve body 211 is mounted on a base 1, and at least part of the base 1 is made of plastic. In this technical solution, the base 1 is injection molded, further reducing weight.

[0035] Example 1

[0036] Combination Figure 1-15As shown, the thermal management integrated module includes a substrate 1, a first valve module 21-1, and a second valve module 21-2. At least a portion of the substrate 1 is made of plastic. The first valve module 21-1 is fixedly connected to the substrate 1, and the second valve module 21-2 is fixedly connected to the substrate 1. The first valve module 21-1 includes a first valve body 211A and a first valve component 215A, which are fixedly connected. The second valve module 21-2 includes a second valve body 211B and a second valve component 215B, which are fixedly connected. The thermal management module includes a connecting pipe assembly 4 and a thermal management component 2. The thermal management component 2 includes at least one of a heat exchanger 22 and a liquid receiver 23. The connecting pipe assembly 4 connects the first valve body 211A to at least one of the thermal management components 2, and / or the connecting pipe assembly 4 connects the second valve body 211B to at least one of the thermal management components 2, and / or the connecting pipe assembly 4 connects the first valve body 211A to the second valve body 211B. The first valve module 21-1 and the second valve module 21-2 are adjacent and spaced apart. The temperature of the refrigerant in the first valve module 21-1 is different from the temperature of the refrigerant in the second valve module 21-2. Specifically, the first valve module 21-1 is fixedly connected to the base 1, and the second valve module 21-2 is fixedly connected to the base 1. The first valve module 21-1 includes at least one valve chamber 2111, and each valve chamber 2111 is correspondingly provided with a valve component 215, that is, the valve component 215 and the valve chamber 2111 are arranged in a one-to-one correspondence. The second valve module 21-2 includes at least one valve chamber 2111, and each valve chamber 2111 is correspondingly provided with a valve component 215. For the thermal management system, the gaseous refrigerant coming out of the compressor is high temperature and high pressure. After the condenser releases heat, the high temperature and high pressure gaseous refrigerant becomes medium temperature and high pressure. High-temperature, high-pressure liquid refrigerant is throttled by an electronic expansion valve to become a low-temperature, low-pressure gas-liquid two-phase system. After absorbing heat in the evaporator, it becomes a low-temperature, low-pressure gas-phase refrigerant and enters the compressor. The refrigerant in the upstream flow channel 101 of the condenser is a high-temperature gas phase, which is the high-temperature side. The refrigerant in the downstream flow channel 101 of the condenser is a medium- or low-temperature side. In related technologies, the valve body 211 or the flow channel 101 plate is made of aluminum or aluminum alloys. The high-temperature side refrigerant and the medium- or low-temperature side refrigerant exchange heat in the valve body 211 or the flow channel 101 plate, which is harmful heat transfer and reduces the performance of the system. It is necessary to reduce the heat transfer between the two. In this technical solution, the valve component 215 in the second valve module 21-2 is located downstream of the condenser in the thermal management system, and the valve component 215 in the first valve module 21-1 is located upstream of the condenser in the thermal management system. The temperature of the refrigerant in the first valve module 21-1 is higher than that of the refrigerant in the second valve module 21-2. The refrigerant flow paths of the two parts are set separately, which can effectively reduce harmful heat transfer. In addition, multiple valve modules 21 are set, which splits the original single flow channel 101 plate into multiple parts. The structure of each valve module 21 is relatively simple and the manufacturing is relatively simple.Of course, in other embodiments, valve modules 21 can be provided in three or more ways, and the number of valve components 215 provided in each valve module 21 can be adjusted according to the complexity of the system.

[0037] The valve module 21 in this technical solution is described in detail. A first plane is defined, which is perpendicular to the thickness direction of the substrate 1. A second plane is defined, which is perpendicular to the first plane. A first direction and a second direction are defined, which are perpendicular to the second direction. The first direction and the second direction form the first plane. For this technical solution, it can be simply understood that the first direction is the length direction of the substrate 1, the second direction is the width direction of the substrate 1, and the second plane is the plane formed by the thickness direction of the substrate 1 and the length direction of the substrate 1, or the second plane is the plane formed by the thickness direction of the substrate 1 and the width direction of the substrate 1. The first valve module 21-1 and the second valve module 21-2 are disposed on the end of the base 1 parallel to the first plane. The first valve module 21-1 and the second valve module 21-2 are adjacent and spaced apart, and are arranged along the first direction. The valve components 215 of the first valve module 21-1 and the second valve module 21-2 are arranged along the first direction. The arrangement of the valve components 215 varies depending on the number of valve components 215. When the number of valve components 215 is relatively small, the valve components 215 can be arranged in a straight line. When the number of valve components 215 is relatively large, if the valve components 215 are arranged in a straight line, the volume in the first direction will be too large. The valve components 215 can be arranged in multiple rows, and the valve components 215 in adjacent rows are staggered, which helps to reduce space. In this technical solution, the valve module 21 includes a control unit 214. Multiple valve components 215 share one control unit 214. The adjacent arrangement of the multiple valve components 215, either in a straight line or staggered in multiple rows, facilitates the installation of the control unit 214 and reduces its size. As shown in the figure, the control unit 214 includes a control box 2141. The multiple valve components 215 are located inside the control box 2141, and the control box 2141 is fixedly connected to the valve body 211. In this technical solution, there are 6 valve components 215, corresponding to 6 valve chambers 2111. The 6 valve chambers 2111 are arranged in two rows, and the two rows of valve chambers 2111 are staggered, that is, the line connecting the axis of the first row of valve chambers 2111 and the adjacent valve chamber 2111 in the second row roughly forms a W shape. The control box 2141 and the valve body 211 are fixedly connected by bolts or screws. In some embodiments, the control box 2141 is mounted on the valve component 215, or the control box 2141 is mounted on the base 1.

[0038] like Figure 8-11As shown, the valve body 211 includes a valve cavity portion 211-1 forming a valve chamber 2111 and a channel portion 211-2 forming a refrigerant passage 2112. The valve body 211 also has a notch portion 211-3, which is located between the valve cavity portion 211-1 and the channel portion 211-2, or between two adjacent valve cavity portions 211-1, or between two adjacent channel portions 211-2. The valve body 211 is made of metal, such as aluminum and aluminum alloys, stainless steel, etc. In this technical solution, the valve body 211 is made of aluminum alloy and is formed by extrusion, forging, die casting, machining, or a combination of the above. The valve body 211 includes a notch 211-3, meaning that during processing, material is stacked in the areas forming the valve cavity 2111 and the channel, while material is omitted in the remaining parts, effectively reducing material usage and weight. The refrigerant channel 2112 mainly connects the external interface of the valve body 2111 to the valve cavity 2111. Therefore, the refrigerant channel 2112 is designed to be as short as possible while meeting requirements, further reducing the volume and weight of the valve body 211. The valve body 211 includes an assembly part for fixing and connecting the control box 2141. The assembly part is located on the valve body 211 near the end of the control box 2141 and around the valve cavity 2111. The assembly part protrudes outward relative to the wall forming the valve cavity 2111. The assembly part has a threaded hole, and a through hole is provided at a relative position in the control box 2141. Bolts or screws pass through the through hole of the control box 2141 and the threaded hole of the valve body 211 to fix and connect the control box 2141 and the valve body 211. Of course, in other embodiments, the assembly part has a through hole, and the control box 2141 has a threaded hole, allowing for flexible design according to the installation direction. Multiple threaded holes are provided on the valve body 211, arranged on opposite edges of the valve body 211 along the second direction, with the first row of threaded holes and the second row of threaded holes being staggered, as is the staggered arrangement of the valve cavity 2111.

[0039] The base 1 includes a first mounting part 151, and the valve module 21 includes a first fixing part 213. Along the thickness direction of the base 1, the first mounting part 151 and the first fixing part 213 are arranged opposite to each other. The first fixing part 213 is located at the end of the valve module 21 away from the valve cavity 2111 port. The first mounting part 151 and the first fixing part 213 are threadedly connected. It should be noted that the valve cavity 2111 port here refers to the mounting port of the valve component 215. Specifically, the valve module 21 is fixedly mounted on the end of the base 1 along its thickness direction, that is, the axial direction of the valve cavity 2111 on the valve module 21 is parallel to the thickness direction of the base 1, and the valve cavity 2111 port is far away from the base 1. The base 1 includes a first end 1-1 and a second end 1-2. The end where the valve module 21 is mounted is defined as the first end 1-1, as shown in the figure. The base 1 includes a first mounting part 151, which includes a first sub-mounting part 151-1 for mounting the first valve module 21-1 and a second sub-mounting part 151-2 for mounting the second valve module 21-2. The first valve module 21-1 includes a first sub-fixing part 213-1. Along the thickness direction of the base 1, the first sub-mounting part 151-1 and the first sub-fixing part 213-1 are arranged opposite to each other. The first sub-fixing part 213-1 is located at the end of the first valve body 211A away from the valve cavity 2111 opening of the first valve body 211A. The first sub-mounting part 151-1 and the first sub-fixing part 213-1 are threadedly connected. The second valve module 21-2 includes the second sub-fixing part 213-2. Along the thickness direction of the base 1, the second sub-mounting part 151-2 and the second sub-fixing part 213-2 are arranged opposite to each other. The second sub-fixing part 213-2 is located at the end of the second valve module 21-2 away from the valve cavity 2111 opening of the second valve module 21-2. The second sub-mounting part 151-2 and the second sub-fixing part 213-2 are threadedly connected. For ease of explanation, the first valve module 21-1 and the second valve module 21-2 are collectively referred to as valve module 21. The first fixing part 213 includes a first sub-fixing part 213-1 of the first valve module 21-1 and a second sub-fixing part 213-2 of the second valve module 21-2. The two have the same or similar structural features, but are located on different valve bodies 211. Similarly, the first mounting part 151 includes a first sub-mounting part 151-1 for mounting the first valve module 21-1 and a second sub-mounting part 151-2 for mounting the second valve module 21-2. The two have the same or similar structural features. Similar to the first sub-fixing part 213-1 and the first sub-mounting part 151-1, which are located at different positions on the base 1, for the sake of simplicity, they will not be described in detail. The following description will take the first sub-fixing part 213-1 and the first sub-mounting part 151-1 as examples: The first sub-mounting part 151-1 includes a first mounting hole 1511 and a first mounting part 1512. The first mounting hole 1511 passes through the end of the first sub-mounting part 151-1 along the thickness direction of the base 1. The first mounting part 1512 abuts against its corresponding first sub-fixing part 213-1. The thermal management module includes a fastener. The fastener passes through the first mounting hole 1511 and is threadedly connected to the first sub-fixing part 213-1.The first sub-fixing part 213-1 extends from the bottom of the valve cavity part 211-1 and / or the channel part 211-2 of the first valve body 211A toward the first end 1-1 of the base 1. The first sub-fixing part 213-1 has a threaded hole, and the opening of the threaded hole faces the base 1. In order to save materials, the first sub-fixing part 213-1 is generally cylindrical. The first sub-mounting part 151-1 protrudes from the mounting surface of the base 1, that is, the first sub-mounting part 151-1 is generally a boss structure. The setting of the mounting part 15 and the protrusion relative to the large flat surface facilitates the assembly of the valve body 211 and the base 1 and can reduce the manufacturing precision. The first sub-mounting part 151-1 has a first mounting hole 1511. The first sub-fixing part 213-1 has a threaded hole. The thermal management module includes a fastener. The fastener can be a screw or nut with external threads. The fastener is inserted into the mounting hole from the second end 1-2 of the base 1 and is threadedly fixedly connected to the threaded hole of the first sub-fixing part 213-1. In this technical solution, fasteners are inserted from the end of the base 1 away from the valve module 21, namely the second end 1-2, to fix the base 1 and the valve module 21. Compared with the same-side mounting and fixing ratio of the valve module 21, the installation space is reduced to a certain extent, thereby making the layout between the components more compact.

[0040] The base 1 includes a reinforcing portion 16, and the base 1 includes at least two first sub-mounting portions 151-1 and at least two second sub-mounting portions 151-2. The reinforcing portion 16 is connected between two adjacent first sub-mounting portions 151-1 or between two adjacent second sub-mounting portions 151-2. The base 1 includes a hollow portion 17, which is located around the first sub-mounting portions 151-1 and the second sub-mounting portions 151-2. The reinforcing portion 16 surrounds and forms a partial hollow portion 17. The reinforcing portion 16 and the first sub-mounting portions 151-1 and the second sub-mounting portions 151-2 are injection molded into an integral structure. In this technical solution, the substrate 1 serves as the support for the thermal management component 2. The substrate 1 is injection molded and has a certain thickness. The number of first mounting parts 151 is defined according to the volume, weight, and other requirements of the valve module 21 design. The first mounting parts 151 are distributed on the frame of the substrate 1. To increase the load-bearing strength, a reinforcing part 16 is provided between two adjacent mounting parts 15. The reinforcing part 16 can be a strip-shaped structure to fix and connect adjacent mounting parts 15, or it can be understood as providing a hollow part 17 to reduce weight while meeting the load-bearing strength requirements of the substrate 1. The aforementioned reinforcing part 16 and mounting part 15 are integrally molded during the injection molding of the substrate 1.

[0041] The base 1 includes a connecting part 18, which is located on the periphery of the base 1. The connecting part 18 is injection molded into an integral structure with the base 1 and is fixedly connected to the vehicle frame.

[0042] The thermal management component 2 also includes a heat exchanger 22, which is fixedly connected to the base 1. The heat exchanger 22 and the first valve module 21-1 are located at the same end of the base 1. The first pipe 41 of the pipe assembly 4 connects the external interface of the heat exchanger 22 and the external interface of the first valve module 21-1. The base 1 includes a second mounting part 152, and the heat exchanger 22 includes a second fixing part 223. The second fixing part 223 is located around the end plate 221 of the heat exchanger 22. The end plate 221 of the heat exchanger 22 is located close to the base 1 relative to the plate 224 of the heat exchanger 22. The second fixing part 223 and the second mounting part 152 are threadedly connected. Specifically, the heat exchanger 22 and the valve module 21 are located at the same end of the base 1. Along the second direction, the heat exchanger 22 and the valve module 21 are arranged adjacent to each other, and the heat exchanger 22 is located below the valve module 21. Here, "below" means downward along the direction of gravity. In this technical solution, the heat exchanger 22 and the valve module 21 are respectively fixed on the base 1 and connected by a pipe. In related technical solutions, the valve module 21 and the heat exchanger 22 are fixed to the refrigerant-side flow channel 101 plate. The refrigerant-side flow channel 101 plate is fixedly connected to the water-side flow channel 101 plate. The refrigerant-side flow channel 101 plate is made of aluminum and aluminum alloy. The increased weight and the complexity of the flow channel 101 on the flow channel 101 plate make manufacturing difficult. In this technical solution, the heat exchanger 22 and valve module 21 are fixed to the plastic substrate 1 by disassembly, and then connected by a pipe. This reduces the volume of the flow channel 101 plate or valve body 211 and reduces the metal usage rate. Connecting the heat exchanger 22 and valve module 21 by a pipe is a mature process that reduces manufacturing difficulty. The pipe also has a certain degree of flexibility, and the positional accuracy of the two connected external interfaces is not high during installation and fixing, resulting in greater flexibility. Specifically, the base 1 includes a second mounting portion 152, which is generally cylindrical and protrudes from the end of the base 1. The second mounting portion 152 includes a second mounting hole 1521 and a second mounting portion 1522. The second mounting hole 1521 penetrates the end of the second mounting portion 152 along the thickness direction of the base 1. The second mounting portion 1522 abuts against its corresponding second fixing portion 223. The thermal management module includes a fastener that passes through the second mounting hole 1521 and is threadedly connected to the second fixing portion 223. The base 1 includes a reinforcing rib 1523, which is arranged circumferentially along the second mounting portion 152. The reinforcing rib 1523 and the second mounting portion 152 are injection molded as a single unit. The heat exchanger 22 includes a second fixing portion 223, which is located circumferentially on the end plate 221 of the heat exchanger 22. The second fixing portion 223 and the second mounting portion 152 are threadedly connected.The heat exchanger 22 includes multiple plates 224 and an end plate 221. The multiple plates 224 are welded and fixed to the end plate 221. The multiple plates 224 are stacked to form a medium flow channel 101. The end plate 221 is close to the first end 1-1 of the base 1 relative to the plates 224. The second fixing part 223 extends from the end face of the end plate 221 toward the first end 1-1 of the base 1. The second fixing part 223 has a threaded hole. The second mounting part 152 is provided in a one-to-one correspondence with the second fixing part 223. In some embodiments, the second fixing part 223 and the end plate 221 of the heat exchanger 22 are integral structures, and the second fixing part 223 protrudes outward from the side wall of the end plate 221. The second fixing part 223 is cylindrical and has a limiting hole. Along the stacking direction of the heat exchanger 22 plates 224, the limiting hole is set opposite to the threaded hole. The limiting hole is mainly used for pre-positioning the heat exchanger 22 on the tooling 6. The second mounting portion 152 extends toward the heat exchanger 22 relative to the first end 1-1 of the base 1. Fasteners are inserted from the second end 1-2 of the base 1 into the through hole of the second mounting portion 152 and are threadedly fixed to the threaded hole of the second fixing portion 223. The mounting direction of the heat exchanger 22 is the same as that of the valve module 21, which simplifies the manufacturing process.

[0043] The first fixing part 213 of the valve module 21 abuts against the first mounting part 151 of the base 1 and is threadedly fixed. The remaining part of the valve module 21 is spaced apart from the base 1. The second fixing part 223 of the heat exchanger 22 abuts against the third mounting part 153 of the base 1 and is threadedly fixed. This can absorb the vibration margin during operation and reduce the wear on the plastic base 1 during operation.

[0044] In this technical solution, the thermal management component 2 includes a valve module 21 and a heat exchanger 22. The valve module 21 includes a valve component 215 and a valve body 211. The valve body 211 has a valve cavity 2111 and a refrigerant channel 2112. The valve cavity 2111 is connected to the refrigerant channel 2112. The valve body 211 includes a first external interface 2121 connected to the heat exchanger 22. The first external interface 2121 is connected to the refrigerant channel 2112. The valve module 21 and the heat exchanger 22 are arranged adjacent to each other. The first external interface 2121 is connected to the heat exchanger 22 through a pipe. The axial direction of the valve cavity 2111 is parallel to the thickness direction of the base 1. Correspondingly, the heat exchanger 22 includes a second external interface 222, which is connected to the first external interface 2121 of the valve module 21. The second external interface 222 of the heat exchanger 22 is located on the same end plate 221 of the heat exchanger 22, and the end plate 221 is arranged opposite to the base 1, that is, the second external interface 222 of the heat exchanger 22 faces the base 1. The first external interface 2121 of the valve module 21 is arranged in the same direction as the second external interface 222 of the heat exchanger 22. The first connecting pipe 41 is defined as the first external interface 2121 of the valve module 21 and the second external interface 222 of the heat exchanger 22. Multiple first connecting pipes 41 can be set according to different thermal management systems. The first connecting pipe 41 can be set with different bending angles according to the position relative to the external interface. Of course, the first connecting pipe 41 can have two ports, which are respectively connected to the external interfaces of the valve module 21 and the heat exchanger 22. The first connecting pipe 41 can also have three or more ports, that is, the first connecting pipe 41 can be a tee or a multi-way, and different connection loops are designed according to different thermal management systems. In this technical solution, the first external interface 2121 connecting the valve module 21 to the heat exchanger 22 and the second external interface 222 connecting the heat exchanger 22 to the valve module 21 are designed in the same direction, and both the first external interface 2121 and the second external interface 222 are set towards the base 1. Firstly, the part of the pipe is hidden on the back of the valve module 21 and the heat exchanger 22, which is good for aesthetics. Secondly, it is convenient for installation and manufacturing, as installation can be completed in the same position without flipping, and the manufacturing process is relatively simple. In this technical solution, the first connecting pipe 41 is welded and fixed to the valve module 21 and the heat exchanger 22. The first connecting pipe 41 includes a limiting part 411 and a mating part 412. At least part of the mating part 412 is located inside the outer interface. The limiting part 411 is far away from the port of the first connecting pipe 41 relative to the mating part 412. The limiting part 411 protrudes from the outer wall of the first connecting pipe 41. The first limiting part 411 includes a first side and a second side. The second side is closer to the outer interface than the first side. During welding, the mating part 412 is inserted into the outer interface. The first connecting pipe 41 is pre-fixed in the outer interface of the valve module 21 and the heat exchanger 22. The solder is limited to the end of the outer interface and the second side. The press is pressed on the first side of the first connecting pipe 41. The first side is the force point of the press, which makes it easy for the first connecting pipe 41 to be evenly stressed during the pressing process.

[0045] The thermal management element includes a reservoir 23, which is fixedly connected to the base 1. The reservoir 23 includes a third external interface 231, which is connected to the fourth external interface 2122 of the valve module 21 via a second connecting pipe 42. The base 1 includes a third mounting portion 153, which includes a third receiving groove. At least a portion of the reservoir 23 is located within the third receiving groove. The base 1 also includes a connector 234, which is threadedly connected to the third mounting portion 153. At least a portion of the reservoir 23 is confined within the space formed by the connector 234 and the third mounting portion 153. Specifically, the liquid reservoir 23 includes a cylindrical body 232 and a cover 233, which are fixedly connected. The cover 233 includes a transition portion 2331 with a communicating channel 2332. A third external interface 231 is located at the transition portion 2331 and communicates with the communicating channel 2332. The communicating channel 2332 communicates with the liquid storage chamber 141 of the liquid reservoir 23. The axial direction of the cylindrical body 232 is perpendicular to the thickness direction of the base 1. The valve module 21 and the heat exchanger 22 are arranged along the axial direction of the cylindrical body 232. This layout is conducive to a compact layout. In this technical solution, the cylindrical body 232 of the liquid reservoir 23 is roughly cylindrical. The receiving groove is recessed from the first end 1-1 of the base 1 to the second end 1-2, and the shape of the receiving groove is similar to the shape of the liquid reservoir 23, i.e., a contoured structure is made. The liquid reservoir 23 is confined within the receiving groove. The connector 234 is fixed to the third mounting part 153. The connector 234 is arc-shaped, and its shape matches the outer wall of the cylinder 232 of the reservoir 23. The inner wall of the connector 234 at least partially abuts against the outer wall of the cylinder 232 of the reservoir 23. The reservoir 23 is fixedly located in the space formed by the connector 234 and the third mounting part 153. The third mounting part 153 has a hollow structure, which can effectively reduce the weight of the base 1. The third external interface 231 of the reservoir 23 and the fourth external interface 2122 of the valve module 21 are connected through the second connecting pipe 42. The third external interface 231 is located in the adapter part 2331 and faces the base 1. The fourth external interface 2122 faces the base 1, and the third external interface 231 and the fourth external interface 2122 have the same orientation, which is beneficial for installation during the manufacturing process. In this technical solution, the connection between the liquid reservoir 23 and the valve module 21 is a movable connection. Specifically, the connecting pipe assembly 4 includes a second connecting pipe 42 and an adapter block 43. The second connecting pipe 42 and the adapter block 43 are fixedly connected. The fixed connection includes welding, bonding, etc. At least part of the connecting pipe is located inside the external interface of the liquid reservoir 23 and / or the valve module 21, and the adapter block 43 is fixedly connected to the liquid reservoir 23 and / or the valve module 21 by fastener threads. Of course, in some technical solutions, part of the external interface of the liquid reservoir 23 is connected to part of the external interface of the heat exchanger 22, and the connection method is as described above as a movable connection, which will not be described in detail here.

[0046] The thermal management module also includes a fluid control element 3. The substrate 1 includes a flow channel portion 10, which has a flow channel 101. The substrate includes a mounting cavity 102, and a portion of the flow channel 101 communicates with the mounting cavity 102. At least a portion of the fluid control element 3 is located in the mounting cavity 102. The fluid control element 3 includes at least one of a water valve 30 and a pump 31. It should be noted that the partial communication between the flow channel 101 and the mounting cavity 102 occurs either when the fluid control element 3 is not installed, or during system operation, through the switching action of the fluid control element 3. In this technical solution, the substrate 1 includes a flow channel 101 for coolant flow and fluid control components 3 such as water valve 30 and pump 31 are fixedly connected to it. The mounting part 15 is fixedly connected to thermal management components such as valve module 21 and heat exchanger 22. That is, the thermal management components 2 on the refrigerant side that drive the refrigerant flow, such as valve module 21, heat exchanger 22, and liquid receiver 23, are fixedly installed on the substrate 1 for coolant flow. This eliminates the need for the refrigerant-side flow channel 101 plate in related technologies, which helps to reduce the weight of the thermal management module and lower the cost.

[0047] The fluid control element 3 includes a water valve 30 and a water pump 31. The water valve 30 and the water pump 31 are located on the same side of the thermal management element, which helps to reduce the thickness of the substrate 1. A first plane is defined, which is perpendicular to the thickness direction of the substrate 1. The flow channel portion 10 forming the flow channel 101 coincides with the projection portion of the thermal management component 2 on the first plane. The thermal management component 2 includes at least one of a valve module 21, a heat exchanger 22, and a liquid receiver 23. The substrate 1 is provided with a mounting position for the refrigerant-side thermal management element. The area of ​​the substrate 1 corresponding to the thermal management element can be hollowed out to reduce weight, or a flow channel 101 on the coolant side can be provided to make full use of space, which is conducive to the miniaturization of the thermal management module.

[0048] In some technical solutions, the thermal management module includes a substrate and a thermal management component 2. The thermal management component 2 is fixedly connected to the substrate. The thermal management component 2 includes at least one of a valve module 21, a heat exchanger 22, and a liquid reservoir 23. At least a portion of the thermal management component 2 is connected via a connecting pipe assembly 4. The substrate 1 is at least partially made of plastic. At least a portion of the connecting pipe assembly 4 is located between the thermal management component 2 and the substrate 1. A first plane is defined, which is perpendicular to the thickness direction of the substrate 1. A second plane is defined, which is perpendicular to the first plane. The projection of at least a portion of the pipe assembly path onto the second plane coincides with the projection of the substrate 1 onto the second plane. The thermal management component 2 is connected via the connecting pipe assembly 4. The substrate 1 provides the load-bearing function of the thermal management component 2. The fact that the projection of at least a portion of the pipe assembly path onto the second plane coincides with the projection of the substrate 1 onto the second plane can be understood as meaning that a portion of the connecting pipe assembly 4 is embedded within the substrate 1, and a gap is provided between the connecting pipe assembly 4 and the outer surface of the substrate 1. The first external interface 2121 of the valve module 21 is connected to the second external interface 222 of the heat exchanger 22 via a first connecting pipe 41. At least a portion of the first connecting pipe 41 is embedded in the base 1. To improve load-bearing strength, the base 1 is a plate with a certain thickness. The base 1 includes a receiving cavity 110, which extends through both ends along the thickness direction of the base 1, and / or the receiving cavity 110 is recessed from one end of the base 1 to the other end. At least a portion of the connecting pipe assembly 4 is located in the receiving cavity 110. It can be understood that the base 1 has a hollow structure; these hollow spaces can accommodate part of the connecting pipe, which not only reduces the weight of the base 1 but also reduces the volume of the thermal management module along the thickness direction. Similarly, the connecting pipe assembly 4 includes a second connecting pipe 42, at least a portion of which is embedded within the base 1.

[0049] The base 1 includes a flow channel 10, which has a flow channel 101 for coolant flow. At least part of the connecting pipe assembly 4 for refrigerant flow and the flow channel 10 for coolant flow are projected onto the second plane. It can be understood that the connecting pipe assembly 4 for refrigerant flow and the flow channel 10 for coolant flow are at least partially disposed on the same plane. Compared with the related art, where the refrigerant side flow channel 101 plate and the coolant side flow channel 101 plate are fixedly connected back to back, the structure of this technical solution is more conducive to space utilization and reduces volume.

[0050] In some technical solutions, the thermal management module includes a base 1, a thermal management component 2, and a fluid control element 3. The base 1 includes a flow channel 10, which has a flow channel 101. The opening of the fluid control element 3 communicates with a portion of the flow channel 101. The fluid control element 3 includes at least one of a water valve 30 and a pump 31. The thermal management component 2 includes at least one of a valve module 21, a heat exchanger 22, and a liquid receiver 23. A connecting pipe assembly 4 communicates with at least two of the thermal management components 2. It should be noted that "at least two" here refers to two of the same thermal management components 2, such as two valve modules 21 and two heat exchangers 22, or two of different thermal management components 2, such as one valve module 21 and one heat exchanger 22, which can be reasonably selected according to different thermal management systems. The number of pipes in the connecting pipe assembly 4 is defined according to the complexity of the thermal management system. The connecting pipe assembly 4 can be a combination of multiple pipes, or a combination of pipes and adapter blocks 43. The connecting pipe assembly 4 can be a two-way structure, or a three-way or multi-way structure composed of multiple pipes. The base 1 includes at least two mounting portions 15, each fixedly connected to a corresponding thermal management component 2. The mounting portions 15 are located at the same end of the base 1. The aforementioned mounting portions 15 refer to all mounting portions 15 fixedly connected to the thermal management component 2, and the number of mounting portions 15 is at least two, meaning there are at least two thermal management components 2. These two thermal management components 2 can be the same or different, and each thermal management component 2 corresponds to one mounting portion 15, all located at the same end of the base 1. It should be noted that, compared to mounting the thermal management components 2 at different ends, this design reduces the volume along the thickness direction and allows for assembly in the same direction, facilitating installation and manufacturing.

[0051] The thermal management component 2 includes a valve module 21 and a heat exchanger 22. The base 1 includes a first end 1-1 and a second end 1-2, which are arranged opposite to each other along the thickness direction of the base 1. The mounting part 15 includes a first mounting part 151 and a second mounting part 152. The first mounting part 151 is fixedly connected to the valve module 21, and the second mounting part 152 is fixedly connected to the heat exchanger 22. The first mounting part 151 and the second mounting part 152 are located at the first end 1-1, or the first mounting part 151 and the second mounting part 152 are located at the second end 1-2. The specific structural features of the first mounting part 151 and the second mounting part 152, and the cooperative structural features of the first mounting part 151 and the second mounting part 152 with the valve module 21 and the heat exchanger 22 are the same as or similar to the above-described technical solutions, and will not be described in detail.

[0052] The connecting pipe assembly 4 includes a first connecting pipe 41, which connects the valve module 21 and the heat exchanger 22. Any two ports of the first connecting pipe 41 face the same direction. This can be understood as all ports of the first connecting pipe 41 facing the same direction. The valve module 21 includes a valve body 211, which includes a first external interface 2121. The heat exchanger 22 includes a second external interface 222. The first connecting pipe 41 connects the second external interface 222 to the first external interface 2121. The second external interface 222 is located on the same end plate 221 of the heat exchanger 22. The first external interface 2121 and the second external interface 222 are arranged in the same direction and along the thickness direction of the base 1, with the first external interface 2121 facing the base 1. Similar to the specific structural features of the first connecting pipe 41, valve body 211, and heat exchanger 22 described above, the fact that the ports of the first connecting pipe 41 face the same direction facilitates manufacturing and assembly, saving assembly time. For example, installation can be completed without flipping the base 1.

[0053] The connecting pipe assembly 4 includes a second connecting pipe 42, which connects to the liquid reservoir 23 and the valve module 21. Any two ports of the second connecting pipe 42 face the same direction. The thermal management component 2 includes the liquid reservoir 23. The mounting part 15 includes a third mounting part 153, which is located at the same end of the base 1 as the first mounting part 151. The liquid reservoir 23 is fixedly connected to the third mounting part 153. The connecting pipe assembly 4 also includes a second connecting pipe 42, which connects to the liquid reservoir 23 and the valve module 21. Any two ports of the second connecting pipe 42 face the same direction. The valve module 21 includes a third external interface 231 and a fourth external interface 2122. The third external interface 231 and the fourth external interface 2122 of the second connecting pipe 42 face the same direction, and the ports of the first connecting pipe 41 and the second connecting pipe 42 also face the same direction. The mating structure between the third mounting part 153 and the liquid reservoir 23 is the same as or similar to the above-described technical solution, and will not be described in detail.

[0054] In this technical solution, a first direction and a second direction are defined, and the first and second directions are perpendicular to each other. Both the first and second directions are perpendicular to the thickness direction of the base 1. The axial direction of the cylinder 232 is perpendicular to the thickness direction of the base 1. The valve module 21 and the heat exchanger 22 are arranged along the axial direction of the cylinder 232. Multiple valve components 215 are arranged along the first direction, or multiple valve modules 21 are arranged along the first direction. The valve module 21 and the heat exchanger 22 are arranged along the second direction. It should be noted that valve module 21 includes at least two valve components 215, each valve component 215 corresponding to a valve chamber 2111. The opening directions of the valve chambers 2111 are the same, and the valve components 215 are arranged adjacent to each other. Valve module 21 includes a control unit 214, and multiple valve components 215 share one control unit 214; that is, the valve components 215 are on the same valve body 211. Alternatively, the thermal management module includes at least two valve modules 21, defined as a first valve module 21-1 and a second valve module 21-2. The first valve module 21-1 and the second valve module 21-2 are arranged adjacent to each other and spaced apart, so the first valve module 21-1 and the second valve module 21-2 share one control unit 214. The above arrangement scheme is beneficial for the compact structure of the thermal management module.

[0055] The fluid control element 3 is located at the same end of the base 1, and the fluid control element 3 and the thermal management element are located at the same end of the base 1, or as follows: Figure 21-22 As shown, the fluid control element 3 and the thermal management component 2 are located at opposite ends of the base 1. That is, it is only necessary to ensure that the thermal management component 2 is located at the same end of the base 1.

[0056] Example 2

[0057] Combination Figure 16-20As shown, a thermal management module includes a substrate 1 and a fluid control element 3. The substrate 1 includes a flow channel 10 with a flow channel 101. The fluid control element 3 has an opening communicating with the flow channel 101. The fluid control element 3 is fixedly or partially connected to the substrate 1. The fluid control element 3 includes at least one of a water valve 30 and a pump 31. The substrate 1 is at least partially made of plastic. The thermal management module also includes a thermal management component 2 and a connecting pipe assembly 4. The thermal management component 2 is fixedly connected to the substrate. The thermal management component 2 includes at least one of a valve module 21, a heat exchanger 22, and a liquid reservoir 23. The connecting pipe assembly 4 communicates with the heat management component 2. At least two. It should be noted that "at least two" here refers to two identical thermal management components 2, such as two valve modules 21, two heat exchangers 22, etc., or two different thermal management components 2, such as one valve module 21, one heat exchanger 22, etc., which can be reasonably selected according to different thermal management systems. The number of pipes in the pipe assembly 4 is defined according to the complexity of the thermal management system. The pipe assembly 4 can be a combination of multiple pipes, or a combination of pipes and adapter blocks 43. The pipe assembly 4 can be a two-way structure, or a three-way or multi-way structure composed of multiple pipes. The base 1 includes a receiving portion 11, and the receiving portion 11 includes a receiving cavity 110, with at least a portion of the pipe assembly 4 and / or at least a portion of the thermal management components 2 located in the corresponding receiving cavity 110. This can be understood as follows: a portion of the connecting pipe assembly 4 is located in the receiving cavity 110, or all of the connecting pipe assembly 4 is located in the receiving cavity 110; or a portion of the thermal management component 2 is located in the receiving cavity 110, or all of the thermal management component 2 is located in the receiving cavity 110; or at least a portion of the connecting pipe assembly 4 and at least a portion of the thermal management component 2 are both located in the receiving cavity 110. In this solution, the thermal management components 2 are respectively integrated on the substrate 1, i.e., on the flow channel 101 plate on the coolant side. The thermal management components 2 are connected to each other through the connecting pipe assembly 4, eliminating the need for the large and heavy flow channel 101 plate on the refrigerant side and reducing the weight of the thermal management module. The substrate 1 includes a receiving portion 11, and the receiving portion 11 includes a receiving cavity 110. At least a portion of the connecting pipe assembly 4 and / or at least a portion of the thermal management component 2 are located in the corresponding receiving cavity 110, i.e., a portion of the connecting pipe assembly 4 and / or the thermal management component 2 is surrounded by the substrate 1, which can improve the load-bearing capacity of the substrate 1 and relatively reduce the volume of the substrate 1 along the thickness direction.

[0058] In this technical solution, the substrate 1 includes a first plate 12 and a second plate 13, which are fixedly connected. The first plate 12 and the second plate 13 cooperate to form at least a portion of the flow channel 101. The receiving portion 11 is located on the first plate 12, and / or the receiving portion 11 is located on the second plate 13. The first plate 12 and the second plate 13 are injection molded. The substrate 1 of this solution has a flow channel 101, which serves as a carrier for the thermal management component 2 and the fluid control element 3, and also has a fluid flow function. The substrate 1 includes a first end 1-1 and a second end 1-2, which are arranged opposite to each other along the thickness direction of the substrate 1. The mounting port of the accommodating cavity 110 is located at one of the first end 1-1 and the second end 1-2, or a portion of the mounting port of the accommodating cavity 110 is located at the first end 1-1 and the other portion of the mounting port of the accommodating cavity 110 is located at the second end 1-2. It can be understood that each thermal management component 2 corresponds to one accommodating cavity 110, and the position of the mounting port of the accommodating cavity 110 determines the mounting direction of the thermal management component 2. That is, the thermal management component 2 can be installed at the same end of the substrate 1 or at different ends of the substrate 1. The substrate 1 includes a reinforcing part 121, which is located between two adjacent accommodating cavities 110. Specifically, the accommodating cavity 110 includes a first accommodating cavity 1101 and a second accommodating cavity 1102, which are arranged adjacent to each other. A first valve module 21-1 is located in the first accommodating cavity 1101, and a second valve module 21-2 is located in the second accommodating cavity 1102. The base 1 includes a reinforcing part 121, which is located between two adjacent accommodating cavities 110, that is, between the first valve module 21-1 and the second valve module 21-2. The reinforcing part 121 extends outward from the bottom of the accommodating cavity 110. When the mounting port of the first accommodating cavity 1101 and the mounting port of the second accommodating cavity 1102 are not in the same direction, the reinforcing part 121 can be a wall portion shared by the wall of the first accommodating cavity 1101 and the wall of the second accommodating cavity 1102. It can also be simply understood that after the layout position of the thermal management component 2 is determined, that is, the thermal management component 2 is installed on the base 1, the space between two adjacent thermal management components 2 is filled to form a reinforcing part 121, which is beneficial to the improvement of the strength of the base 1.

[0059] In some technical solutions, the substrate 1 has a mounting cavity 102, with at least a portion of the fluid control element 3 located in the mounting cavity 102. The mounting opening of the mounting cavity 102 is arranged along the thickness direction of the substrate 1, forming an outer wall of the mounting cavity 102 that partially overlaps with the inner wall of the accommodating cavity 110; or the outer wall of the flow channel 101 partially overlaps with the inner wall of the accommodating cavity 110. Specifically, when the fluid control element 3 and the thermal management component 2 are located at the same end of the substrate 1, for example, when the fluid control element 3 is a water pump 31, and part of the water pump 31 is located in the mounting cavity 102, then the accommodating cavity 110 for mounting the thermal management component 2 shares a portion of its wall with the mounting cavity 102. Thus, both the fluid control element 3 and the thermal management component 2 are embedded in the substrate 1, and the height difference between the fluid control element 3 and the thermal management component 2 along the thickness direction of the substrate 1 can be adjusted as needed, which is beneficial for reducing the volume of the thermal management module along the thickness direction. When the fluid control element 3 and the thermal management component 2 are disposed at different ends of the base 1, the fluid control element 3 and the base 1 may be fixedly connected at their end faces, and the opening of the fluid control element 3 is connected to the flow channel 101 of the base 1. At this time, the outer wall forming the flow channel 101 partially overlaps with the inner wall forming the accommodating cavity 110, which is also beneficial to the reduction of the volume along the thickness direction in the thermal management module.

[0060] In this technical solution, the accommodating cavity 110 can take various forms, such as the accommodating cavity 110 penetrating both ends of the base 1 along its thickness direction, and / or the wall forming the accommodating cavity 110 includes a bottom wall portion 111, with the bottom wall portion 111 positioned opposite to the mounting port of the accommodating cavity 110. Specifically, the thermal management component 2 includes a valve module 21, which includes a valve component 215 and a valve body 211. The connecting pipe assembly 4 connects the valve body 211 to at least one of the heat exchanger 22 and the liquid reservoir 23. The accommodating cavity 110 includes a first accommodating cavity 1101, with at least a portion of the connecting pipe assembly 4 located in the corresponding first accommodating cavity 1101. The first accommodating cavity 1101 penetrates the first end 1-1 and the second end 1-2 of the base 1. As shown in Embodiment 1, a portion of the connecting pipe assembly 4 is located in the hollow portion 17 of the base 1. The specific structure is as shown in Embodiment 1 and will not be described in detail.

[0061] In embodiment 2, the thermal management component 2 includes a valve module 21, which includes a valve component 215 and a valve body 211. The accommodating cavity 110 includes a second accommodating cavity 1102, and the wall forming the second accommodating cavity 1102 includes a bottom wall portion 111. At least a portion of the valve module 21 is located in the second accommodating cavity 1102. The valve body 211 is fixedly connected to the bottom wall portion 111. The connecting pipe assembly 4 connects the valve body 211 to at least one of the heat exchanger 22 and the liquid reservoir 23. At least a portion of the connecting pipe assembly 4 is located in the second accommodating cavity 1102. At least a portion of the connecting pipe assembly 4 and at least a portion of the thermal management component 2 are both located in the second accommodating cavity 1102. Of course, in some other embodiments, the accommodating cavity 110 with the bottom wall portion 111 and the accommodating cavity 110 with the hollow structure coexist.

[0062] The thermal management component 2 includes a heat exchanger 22, which is disposed on the same side of the base 1 as the valve module 21. The valve module 21 includes a first external interface 2121, and the heat exchanger 22 includes a second external interface 222. The second external interface 222 is located on the same end plate 221 of the heat exchanger 22. Along the thickness direction of the base 1, the first external interface 2121 and the second external interface 222 have the same orientation, and the second external interface 222 faces the base 1. The connecting pipe assembly 4 includes a first connecting pipe 41, which connects the second external interface 222 and the first external interface 2121.

[0063] The thermal management component 2 includes a liquid reservoir 23, and the receiving cavity 110 includes a third receiving cavity 1103. At least a portion of the liquid reservoir 23 is located in the third receiving cavity 1103. The liquid reservoir 23 is fixedly connected to the base 1. The liquid reservoir 23 includes a third external interface 231, which is disposed towards the base 1 along the thickness direction of the base 1. The valve module 21 includes a fourth external interface 2122, which is disposed towards the base 1. The second connecting pipe 42 of the connecting pipe assembly 4 connects the third external interface 231 and the fourth external interface 2122, and at least a portion of the second connecting pipe 42 is located in the third receiving cavity 1103. The specific structural features of the heat exchanger 22 and the liquid reservoir 23, their communication relationship with the connecting pipe assembly 4, and their connection structural features with the base 1 are the same as or similar to those in Embodiment 1, and will not be described in detail here.

[0064] In some technical solutions, a first plane is defined, perpendicular to the thickness direction of the substrate 1, and a second plane is defined, perpendicular to the first plane. At least a portion of the projection of the connecting pipe assembly 4 onto the second plane coincides with the projection of the flow channel portion 10 onto the second plane. At least a portion of the projection of the connecting pipe assembly 4 onto the first plane coincides with the projection of the thermal management component 2 onto the first plane, and / or the projection of the flow channel portion 10 onto the first plane coincides with the projection of a portion of the thermal management component 2 onto the first plane. This can be simply understood as follows: to make the thermal management module structure more compact, portions of the connecting pipe assembly 4 and the flow channel portion 10 are arranged side-by-side with the thermal management component 2 along the thickness direction of the substrate 1, which relatively reduces the area projected onto the first plane by the thermal management module.

[0065] In some technical solutions, the substrate 1 includes a reservoir 14 for storing coolant. Part of the reservoir 14 is injection molded integrally with the first plate 12, and another part is injection molded integrally with the second plate 13. The reservoir 14 coincides with the projection of the thermal management component 2 onto the first plane. Simply put, the substrate 1 has a reservoir 14, which, while meeting the requirements of the thermal management system, can be located in the empty spaces between the thermal management components 2 and the fluid control elements 3. For example, the reservoir 14 coincides with the projection of the valve module 21 onto the first plane, a portion of the reservoir 14 is located on both sides of the valve module 21, and at least a portion of the reservoir 14 coincides with the projection of the valve module 21 onto the second plane. Because the substrate 1 is injection molded, it has high plasticity and can fully utilize the gaps between the components to fill the reinforcing portion 121, the flow channel portion 10, and the reservoir 14, which is more conducive to the miniaturization and weight reduction of the thermal management module.
