Description

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] As a key component for pressure regulation and gas removal within the flow channel plate when switching between different operating modes, the kettle plays an important role in the thermal management integrated module.

[0003] In related technologies, an external pipe is installed on the flow channel plate to introduce the gas-carrying fluid into the kettle. The gas is then thoroughly degassed into the kettle's expansion cavity by the prolonged residence of the gas-carrying liquid within the kettle and the buoyancy of the gas itself. The gas is then discharged to the external environment through the degassing structure on the kettle lid. This degassing structure requires additional degassing pipes, making the structure relatively complex; or as... Figure 20 The kettle and flow channel plate are designed as an integrated structure. A partition is installed at the connection between the kettle and the flow channel to divide the channel into an exhaust channel and a return channel. The liquid with gas enters the kettle through the exhaust channel for internal circulation. The gas is discharged to the external space through the kettle lid. At the same time, the degassed liquid is replenished into the return channel to continue circulation. Another part enters the water pump for return circulation. Although this degassing structure does not require external piping, the exhaust condition is singular and cannot meet the degassing needs of various conditions and flow directions. The degassing efficiency is relatively low. Summary of the Invention

[0004] The purpose of this invention is to provide a thermal management module to improve the degassing efficiency of the thermal management module.

[0005] The technical solution of this application provides a thermal management module, including a kettle and a flow channel plate assembly, wherein the kettle and the flow channel plate assembly are fixedly connected; the kettle includes a connecting part, the connecting part includes a connecting port, the connecting port includes a first vent, a second vent, and a liquid outlet; the flow channel plate assembly includes a first venting channel, a second venting channel, a liquid replenishment channel, a first connecting port, a second connecting port, and a third connecting port; the first venting channel and the first vent are connected, the second venting channel and the second vent are connected, the liquid outlet is connected to the liquid replenishment channel, and the first connecting port, the second connecting port, and the third connecting port are connected to the external interface of the flow channel plate assembly; the thermal management module includes a first venting path, a second venting path, and a liquid replenishment path; the first venting path includes a first connecting port, a first venting channel, and a first vent; the second venting path includes a second connecting port, a second venting channel, and a second vent; the liquid replenishment path includes a liquid outlet, a liquid replenishment channel, and a third connecting port.

[0006] In the technical solution of this application, the flow channel plate assembly includes a first exhaust channel, a second exhaust channel, and a liquid replenishment channel. The first exhaust channel is connected to the first exhaust port, the second exhaust channel is connected to the second exhaust port, and the liquid outlet is connected to the liquid replenishment channel. That is, the fluid entering from the first connection port is divided into two parts. One part enters the water tank through the first exhaust channel and the first exhaust port, and after being vented by the water tank, it returns to the third connection port through the liquid outlet and the liquid replenishment channel to participate in the loop circulation. The other part directly enters the third connection port to participate in the loop circulation. Similarly, the fluid entering from the second connection port is divided into two parts. One part enters the water tank through the second exhaust channel and the second exhaust port, and after being vented by the water tank, it returns to the third connection port through the liquid outlet and the liquid replenishment channel to participate in the loop circulation. The other part directly enters the third connection port to participate in the loop circulation. Compared with the degassing structure in related technologies, this solution can remove gas from the flow channel plate assembly under at least two operating conditions, thereby improving the degassing efficiency. Furthermore, this solution employs two exhaust channels, each corresponding to a different connecting port. Compared to a solution where two connecting ports correspond to one exhaust channel, this approach offers greater flexibility in the layout of the flow channels and connecting ports. This is because the connecting ports are configured to correspond to the external interfaces on the flow channel plate that connect to other thermal management components, and the connecting ports are located upstream of the exhaust channels. If two connecting ports correspond to one exhaust channel, the layout space of the connecting ports on the flow channel plate would be limited. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] It should be understood that although various information may be described using terms such as "first," "second," "third," and "fourth" in this application, this 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 features of the various technical solutions in this application can complement or substitute for each other.

[0031] 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.

[0032] refer to Figure 1-18 As shown, the thermal management module includes a flow channel plate assembly 2, a fluid pump 50, and a valve component 3. The fluid pump 50 is fixedly connected to or limited to the flow channel plate assembly 2, and the fluid pump 50 is connected to the flow channel within the flow channel plate assembly 2. The fluid pump 50 provides power to the fluid within the flow channel plate assembly 2, enabling the fluid to circulate under different operating modes. The valve component 3 is fixedly connected to the flow channel plate assembly 2, and the valve component 3 is connected to the flow channel within the flow channel plate assembly 2. The valve component 3 can control the switching of different flow channels in the flow channel plate assembly 2, that is, change the flow direction of the fluid, thereby forming different system loops.

[0033] The flow plate assembly 2 includes a flow channel portion 23 and a mounting portion 24. The flow channel portion 23 includes a first flow channel 231 and a second flow channel 232. The mounting portion 24 is used to mount a fluid pump 50. The fluid pump 50 includes a first pump 51 and a second pump 52. The first flow channel 231 and the first pump 51 form at least a portion of a first circuit, and the second flow channel 232 and the second pump 52 form at least a portion of a second circuit. The flow plate assembly 2 includes a liquid inlet 25 and a channel 26 that communicate with the kettle 8. The liquid inlet 25 communicates with the first flow channel 231, and the channel 26 communicates with the second flow channel 232 and the liquid inlet 25. The wall portion forming the second flow channel 232 includes a first wall portion 233. The flow plate assembly 2 includes a first channel 234. The first channel 234 has an opening in the first wall portion 233. The first channel 234 communicates with the second flow channel 232 and the channel 26. The flow area of ​​the first channel 234 is smaller than the flow area of ​​the second flow channel 232. In the relevant technical solutions, the number of independent circulation loops in the thermal management system corresponds one-to-one with the number of liquid replenishment ports 25 in the kettle 8. That is, if there are two independent loops in the thermal management system, such as the battery loop and the motor loop, in order to enable the fluid volume to increase due to thermal expansion when the battery loop and the motor loop operate independently, a liquid replenishment port 25 needs to be set on each loop to connect with the kettle 8. The kettle 8 is equipped with two chambers, which are connected to the battery loop and the motor loop respectively. An opening is set between the chambers to connect and balance the liquid level. When the fluid volume in the battery loop and the motor loop increases due to thermal expansion, under the action of pressure, the excess fluid in the battery loop and the motor loop should be discharged into the kettle 8 through their respective liquid replenishment ports 25. However, under the condition of battery and motor series operation, due to the difference in system flow resistance and the flow resistance of the exhaust and liquid replenishment structure, a significant liquid level difference is generated in the kettle 8 (the opening cannot balance the liquid level). When the system flow rate is large, the kettle 8 chamber with the least flow resistance will be drained, affecting the performance of the system. In this design, the first and second loops share a single replenishment port 25, which is connected to the first flow channel 231 of the first loop. A channel 26 is provided on the flow channel plate assembly 2, connecting the replenishment port 25 and the second flow channel 232 of the second loop. It should be noted that in this design, the first and second flow channels 231 and 232 are not directly connected, but can be indirectly connected under certain operating modes, such as when the first and second loops are connected in series. The flow area of ​​the second channel 236 is smaller than that of the second flow channel 232, reducing the amount of fluid diverted through the channel 26 during system circulation, thus preventing insufficient fluid in the circulation loop and affecting the performance of the thermal management system. Because the first and second loops share a single replenishment port 25, only one chamber is needed in the kettle 8, preventing the significant liquid level difference in the kettle 8 under battery and motor series operation, which could lead to the kettle 8 chamber drying out when the system flow rate is high.Of course, depending on the requirements of different thermal management systems, the number of valve components 3 and fluid pumps 50 will vary, as will the number of circuits in the thermal management system. As long as at least any two circuits share a single replenishment port 25, the solution is within the scope of protection of this application. That is, the thermal management system has two or more circuits, the thermal management system has only one replenishment port 25, or the thermal management system has at least two circuits sharing a single replenishment port 25, and other circuits using a different replenishment port 25.

[0034] like Figure 1-12 As shown, a specific embodiment will be described in detail below. In this embodiment, the thermal management module includes a valve component 3, and the fluid pump 50 includes a first pump 51, a second pump 52, and a third pump 53, which are respectively fixedly connected or limitedly connected to the flow channel plate assembly 2. The fixed connection methods include bolt connection, welding, bonding, or a combination of two or more of the above methods, and the limited connection includes snap-fit ​​connection, etc. The first flow channel 231 and the first pump 51 of the flow channel plate assembly 2 form at least a part of the first circuit, the second flow channel 232 and the second pump 52 form at least a part of the second circuit, and the third flow channel 237 and the third pump 53 form at least a part of the third circuit. The valve component 3 enables at least two of the first, second, and third circuits to be connected in series, or the first, second, and third circuits to operate independently.

[0035] The flow channel plate assembly 2 includes a first plate 27 and a second plate 28, which are fixedly connected. The first plate 27 and the second plate 28 are fixedly connected to form at least a portion of the flow channel and the channel 26. Specifically, the first plate 27 has a first groove 271, the opening of which faces the second plate 28, and / or the second plate 28 has a second groove 281, the opening of which faces the first plate 27. The first plate 27 and the second plate 28 are fixedly connected to form at least a portion of the first flow channel 231, the second flow channel 232, and the channel 26. That is, the wall portion forming the first flow channel 231, the second flow channel 232, and the channel 26 includes the wall portion forming the first groove 271 and / or the wall portion forming the second groove 281. The first wall portion 233 is located in at least one of the first plate 27 and the second plate 28. Understandably, one of the first plate 27 and the second plate 28 has a groove, while the other, corresponding to the groove, is a flat plate structure, enclosing at least a portion of the flow channel or channel 26; or the first plate 27 has a groove, and the second plate 28 also has a groove at a position corresponding to the first plate 27, thereby enclosing at least a portion of the flow channel or channel 26. The number of first grooves 271 and second grooves 281 can be set to multiple according to the system requirements. In this technical solution, the first plate 27 and the second plate 28 are made of plastic material and are integrally molded by injection molding. In other technical solutions, the first plate 27 and the second plate 28 can be made of metal material and formed by die casting, forging, stamping, machining, or a combination of the above processes. Of course, the first plate 27 and the second plate 28 can also be a combination of metal and plastic materials, that is, integrally molded by injection molding with metal parts as inserts. Plastic materials are lightweight, while metal materials have high strength, and can be selected according to different requirements. The mounting part 24 has a first mounting cavity 241, a second mounting cavity 242 and a third mounting cavity 243. The first mounting cavity 241, the second mounting cavity 242 and the third mounting cavity 243 are located in any one of the first plate 27 and the second plate 28, that is, they can be located in the same plate or in different plates. The first pump 51 is at least partially located in the first mounting cavity 241 and is fixedly connected or limitedly connected to the flow channel plate assembly 2. The second pump 52 is at least partially located in the second mounting cavity 242 and is fixedly connected to the flow channel plate assembly 2. The third pump 53 is at least partially located in the second mounting cavity 242 and is fixedly connected to the flow channel plate assembly 2. The inlet and outlet of the first pump 51, the second pump 52 and the third pump 53 are respectively connected to the flow channel of the flow channel plate assembly 2. It should be noted that in some embodiments, the fluid pump 50 includes a pump casing and an impeller assembly, with the impeller assembly located inside the pump casing and the inlet and outlet of the fluid pump 50 located on the pump casing. In other embodiments, the impeller assembly of the fluid pump 50 is directly located in the mounting cavity, that is, the pump casing of the fluid pump 50 and the flow channel plate assembly 2 are an integral structure.The flow channel plate assembly 2 includes a first flow channel 231, a second flow channel 232 and a third flow channel 237. The first flow channel 231 is connected to the first mounting cavity 241, the second flow channel 232 is connected to the second mounting cavity 242, the third flow channel 237 is connected to the third mounting cavity 243, and the first flow channel 231 is connected to the liquid replenishment port 25. The second flow channel 232 is located upstream of the second pump 52, and the third flow channel 237 is located upstream of the third pump 53. It is understood that the second flow channel 232 is connected to the inlet of the second pump 52, and the third flow channel 237 is connected to the inlet of the third pump 53. The wall portion forming the second flow channel 232 includes a first wall portion 233, which is located in at least one of the first plate 27 and the second plate 28. That is, the first wall portion 233 can be located in the first plate 27 or the second plate 28. Of course, the first plate 27 and the second plate 28 enclose each other to form the first wall portion 233. The first wall portion 233 includes a first channel 234, which connects the second flow channel 232 and the channel 26. The first channel 234 is located upstream of the second pump 52 and is located in at least one of the first plate 27 and the second plate 28. Similarly, the wall portion forming the third flow channel 237 includes a second wall portion 235, which is located in at least one of the first plate 27 and the second plate 28. The second wall portion 235 includes a second channel 236, which connects the third flow channel 237 and the channel 26. The second channel 236 is located upstream of the third pump 53. It should be noted that the channels described below refer to the first channel 234, the second channel 236, or third channels, fourth channels, etc. with similar functions. For ease of description, they are collectively referred to as channels. In this technical solution, the flow area of ​​the channel is equivalent to the area of ​​a hole with a diameter of 0.5-4 mm. If the flow area of ​​the channel is too large, too much fluid will be diverted from the system loop, affecting the system performance. If the area of ​​the channel is too small, it will not meet the liquid replenishment requirements. Or, when the volume of fluid in the flow channel plate assembly 2 increases due to thermal expansion, if the excess fluid in the loop cannot be drained into the water tank 8 in time, the flow channel plate will be at risk of leakage. Furthermore, the flow area of ​​the channel is equivalent to the area of ​​a hole with a diameter of 1-3 mm. This can be understood as the channel's cross-sectional shape being either circular or non-circular. When the channel's cross-section is non-circular, the flow area is equivalent to the area of ​​a circular cross-section. In this technical solution, the flow area of ​​channel 26 is smaller than the flow area of ​​the second flow channel 232, which reduces the volume of the flow channel plate assembly 2 to a certain extent.

[0036] When the thermal management system is in operation and the fluid level in the system loop decreases, the first flow channel 231 connects to the replenishment port 25. The first loop is replenished through the replenishment port 25 and the first flow channel 231. It can be understood that replenishment can be performed on any circulation involving the first loop, such as when the first loop circulates independently or when the first loop is connected in series with at least one of the second or third loops. No replenishment is performed when the second or third loop circulates independently. When the first and second loops operate independently, and the volume of fluid in the system increases due to thermal expansion, the flow channel plate may leak if the amount of fluid in the second loop cannot be reduced. This technical solution uses channel 26, where excess fluid in the second loop enters the replenishment port 25 and then the water tank 8, thereby reducing the flow rate in the second flow channel 232 and minimizing the risk of leakage due to fluid expansion. Excess fluid in the first loop enters the replenishment port 25 through the first flow channel 231 and then the water tank 8. Channel 26 can regulate the flow rate in the flow channel plate assembly 2 after the fluid in the second flow channel 232 increases in volume due to thermal expansion, reducing the mutual influence between the fluid in the first flow channel 231 and the fluid in the second flow channel 232, thus improving the performance of the thermal management system. Compared to related technologies that use an independent loop with one replenishment port 25, this technical solution is structurally simpler and optimizes system performance.

[0037] To reduce the flow rate diverted by channel 26 when at least one of the first, second, and third loops is connected in series, which would affect the normal operation of the system if channel 26 diverts too much flow, the flow channel plate assembly 2 includes a guide section 29 located within channel 26. The guide section 29 has a first end 291 fixedly connected to the wall forming channel 26, and a second end 292 spaced apart from the wall forming channel 26. This can be understood as the guide section 29 being integrally formed with one of the plates of the flow channel plate assembly 2, or the guide section 29 and the flow channel plate assembly 2 being separate structures, fixedly connected by welding, bonding, or other processes. The specific structure of the guide section 29 is not limited. One end of the guide section 29 is fixedly connected to the wall forming the flow channel plate, and the other end is spaced apart from the wall forming channel 26, i.e., a space is reserved between them for fluid passage. The guide section 29 increases the flow resistance of the fluid within channel 26, thereby reducing the flow diversion within channel 26. Figure 6-8As shown, a specific embodiment of the guide section 29 will be described in detail below. The second end 292 of the guide section 29 extends away from the first channel 234, that is, the axis of the guide section 29 and the first channel 234 are set at a certain acute angle, and multiple guide sections 29 are provided, with two adjacent guide sections 29 being arranged opposite each other; that is, the multiple guide sections 29 are arranged in a figure-eight structure. Two adjacent guide sections 29 are the first guide section 293 and the second guide section 294. The first guide section 293 and the second guide section 294 are respectively fixed on opposite sides of the wall forming the channel 26. The end of the first guide section 293 and the end of the second guide section 294 form a space for fluid to pass through, that is, the fluid flows in a straight line; or the fixing point of the first guide section 293 and the wall forming the channel 26, and the fixing point of the second guide section 294 and the wall forming the channel 26 are opposite and staggered, that is, the fluid flows in an S-shape. The flow guide 29 is located in at least one of the first plate 27 and the second plate 28, and the multiple flow channels 23 are all located in the first plate 27, or the multiple flow channels 23 are all located in the second plate 28, or the multiple flow channels 23 are partially located in the first plate 27 and partially located in the second plate 28.

[0038] In this application, the channel 26 can also remove gas from the system loop. When the first loop circulates alone, or when the first loop is connected in series with at least one of the second or third loops, channel 26 can remove gas from the second or third loop. Along the direction of gravity, the position of the liquid inlet 25 is higher than the position of the first channel 234; as... Figure 2-8 As shown, the flow channel plate assembly 2 is placed longitudinally, meaning its thickness direction is perpendicular to the direction of gravity. In this configuration, the position of the liquid inlet 25 is higher than that of the first channel 234, which facilitates the upward floating of gas into the liquid inlet 25. The first channel 234 is located at the highest point of the second flow channel 232, where the gas density is relatively low, and the gas flows in the opposite direction to gravity. Therefore, the first channel 234 being located at the highest point of the second flow channel 232 is conducive to gas accumulation. The first wall portion 233 includes a first section 2331, a second section 2332, and a third section 2333. The second section 2332 is higher than both the first section 2331 and the third section 2333, and it is arc-shaped. The first wall portion 233 is the wall portion that forms the second flow channel 232. The first section 2331 is connected to the valve port of the valve component 3, and the third section 2333 is connected to the second pump 52. The second section 2332 connects the first section 2331 and the third section 2333, and the second section 2332 has an arc-shaped structure, that is, the second section 2332 protrudes upward relative to the first section 2331 and the third section 2333. In order to better collect gas, if the second section 2332 is a straight section, it will not be conducive to the collection of gas. The arc-shaped section provides a temporary storage space for gas, which is more conducive to exhaust.

[0039] Channel 26 includes a main channel 261 and at least one branch channel 262. The main channel 261 is connected to the liquid replenishment port 25, and each branch channel 262 connects the main channel 261 to its corresponding flow channel. This can be understood as follows: depending on the configuration of different thermal management systems, different loops need to operate independently in the system, such as battery loops, radiator loops, and heater loops. A main channel 261 is set up, connected to the liquid replenishment port 25, and the branch channels 262 are correspondingly set to system loops, relatively simplifying the structure of channel 26. The guide section 29 can be located within the branch channel 262 or within the main channel 261. Along the direction of gravity, the position of the second channel 236 is lower than the position of the liquid replenishment port 25, and the main channel 261 extends upward from the branch channel 262 furthest from the liquid replenishment port 25 to the liquid replenishment port 25. This facilitates both venting and liquid replenishment.

[0040] During the operation of the thermal management module, some gas accumulates within the flow channel plate assembly 2. If this gas cannot be removed in time, it will affect the performance of the thermal management system. Related technologies involve introducing gas-carrying fluid into the kettle 8 via an external pipe installed on the flow channel plate. The gas is then thoroughly degassed into the expansion cavity of the kettle 8 by the prolonged residence of the gas-laden liquid within the kettle and the buoyancy of the gas itself. Subsequently, the gas is discharged to the external environment through the degassing structure of the kettle 8 lid. This degassing structure requires additional degassing pipes, making the structure relatively complex. The above scheme describes the degassing of the second and third loops in the thermal management module. The degassing structure of the first loop is described in detail below. The thermal management module includes a kettle 8 and a flow channel plate assembly 2, which are fixedly connected. The fixed connection methods include threaded connection, welding, and bonding, and the threaded connection includes bolt connection or screw connection. Specifically, the kettle 8 includes a connecting part 81, which includes a connecting port 082. The flow channel plate assembly 2 includes an assembly part 20, which includes a liquid inlet 25. The liquid inlet 25 communicates with the first flow channel 231. The connecting port 082 and the liquid inlet 25 are arranged opposite to each other. The connecting part 81 and the assembly part 20 are fixedly connected by threads. Alternatively... The connection is fixed by welding, bonding or other methods; when the connecting part 81 and the assembly part 20 are threadedly fixed, the liquid inlet 25 and the connection port 082 are sealed to reduce leakage; the flow channel plate assembly 2 includes the assembly part 20, which has an assembly groove 201; the connecting part 81 of the kettle 8 has a connection port 82 forming the connection port 082, which protrudes toward the flow channel plate assembly 2; at least part of the connection port 82 is located in the assembly groove 201; the assembly part 20 includes a sealing groove 202, which is located on the outer periphery of the liquid inlet 25; the thermal management module includes a seal, at least part of which is located in the sealing groove 202; the seal is radially or end-face pressed between the connection port 82 and the assembly part 20. Alternatively, in some instances, the connecting portion 81 of the kettle 8 abuts against the end face of the assembly portion 20, meaning at least one of the connecting portion 81 and the assembly portion 20 has a sealing groove 202, with a seal located within the sealing groove 202, and the end face of the seal pressed between the connecting portion 82 and the assembly portion 20. Or, the sealing groove 202 is located circumferentially in the connecting portion 82 or the assembly portion, and the opening of the sealing groove 202 is radially positioned towards the replenishment port 25, in which case the seal is radially pressed between the connecting portion 82 and the assembly portion 20. The assembly portion 20 protrudes from the first plate 27, meaning the assembly portion 20 protrudes relative to the end face of the first plate 27, and is located on the side of the first plate 27 opposite to the first groove. The assembly portion 20 includes one of a threaded hole or a through hole, and the connecting portion 81 includes the other of a threaded hole or a through hole. The threaded hole or through hole is located near the replenishment port 25. The thermal management module includes fasteners that securely connect the assembly portion 81 and the connecting portion 81.In this technical solution, the fasteners are bolts or screws. For a more secure connection, at least two fasteners are provided in this technical solution, and the fasteners are positioned close to the liquid inlet 25 to reduce liquid leakage between the connection port 082 and the liquid inlet 25.

[0041] The kettle 8 includes a connection port 082, which includes a first vent 821, a second vent 822, and a liquid outlet 823. All three ports are connected to the inner cavity of the kettle 8, meaning the connection port 082 is divided into the first vent 821, the second vent 822, and the liquid outlet 823. The flow channel plate assembly 2 includes a first flow channel 231, which includes a first vent channel 021, a second vent channel 022, and a liquid replenishment channel 023. The first vent channel 021 is connected to the first vent 821, the second vent channel 022 is connected to the second vent 822, and the liquid outlet 823 is connected to the liquid replenishment channel 023. The first flow channel 231 also includes a first connecting port 024, a second connecting port 025, and a third connecting port 026. The first connecting port 024 is connected to the first vent channel 021, the second connecting port 025, and the third connecting port 026. The connecting port 025 is connected to the second exhaust channel 022, and the second connecting port 025 is connected to the third connecting port 026. Part of the fluid within the flow channel plate assembly 2 can enter the water tank 8 through the first connecting port 024, the first exhaust channel 021, and the first exhaust port 821, and then flow through the liquid outlet 823 and the liquid replenishment channel 023 to the third connecting port 026; and / or, part of the fluid within the flow channel plate assembly 2 can enter the water tank 8 through the second connecting port 025, the second exhaust channel 022, and the second exhaust port 822, and then flow through the liquid outlet 823 and the liquid replenishment channel 023 back to the third connecting port 026. The thermal management module includes a first exhaust path, a second exhaust path, and a liquid replenishment path; the first exhaust path includes the first connecting port 024, the first exhaust channel 021, and the first exhaust port 821; the second exhaust path includes the second connecting port 025, the second exhaust channel 022, and the second exhaust port 822; the liquid replenishment path includes the liquid outlet 823, the liquid replenishment channel 023, and the third connecting port 026.Understandably, the fluid entering through the first connecting port 024 is divided into two parts. Due to the buoyancy of the gas itself, most of the fluid containing air bubbles enters the kettle 8 through the first exhaust channel 021 and the first exhaust port 821. The gas is thoroughly degassed by the prolonged residence of the gas-laden liquid in the kettle and the buoyancy of the gas itself, eventually reaching the expansion cavity of the kettle 8. Then, it is discharged to the external environment through the degassing structure of the kettle 8 lid, and then returns to the third connecting port 026 through the liquid outlet 823 and the liquid replenishment channel 023 to participate in the loop circulation. The other part directly enters the third connecting port 026 to participate in the loop circulation. Similarly, the fluid entering through the second connecting port... The fluid 025 enters and is divided into two parts. One part enters the water tank 8 through the second exhaust channel 022 and the second exhaust port 822. After being vented by the water tank 8, it returns to the third connecting port 026 through the liquid outlet 823 and the liquid replenishment channel 023 to participate in the loop circulation. The other part directly enters the third connecting port 026 to participate in the loop circulation. In this technical solution, the structure of dual exhaust through a single liquid replenishment port 25 greatly improves the exhaust efficiency of the thermal management module. Compared with the degassing structure in related technologies, this solution can remove the gas in the flow channel plate assembly 2 under at least two operating conditions, thus improving the degassing efficiency. Furthermore, this solution uses two exhaust channels 26, each corresponding to a different connecting port. Compared with the solution where two connecting ports correspond to one exhaust channel 26, the layout of the flow channel and connecting ports is more flexible. Since the connecting ports are set to correspond to the external interfaces on the flow channel plate that connect to other thermal management components, and the connecting ports are located upstream of the exhaust channels 26, if two connecting ports correspond to one exhaust channel 26, the layout space of the connecting ports on the flow channel plate would be limited.

[0042] In this technical solution, the water jug ​​8 is positioned above the flow channel plate assembly 2 along the direction of gravity, and the flow channel plate assembly 2 is placed vertically, meaning that the thickness direction of the flow channel plate assembly 2 is perpendicular to the direction of gravity. The liquid inlet 25 of the water flow channel plate assembly 2 is positioned at a relatively high position relative to other connecting ports or flow channels of the flow channel plate assembly 2. Specifically, the first flow channel 231 is provided with a first connecting port 024, a second connecting port 025, and a third connecting port 026. It should be noted that the above-mentioned connecting ports are connected to the external interfaces of the flow channel plate assembly 2. The external interfaces include external interfaces connected to the valve component 3 and the fluid control element of the pump, as well as external interfaces connected to thermal management components such as battery A, motor B, and radiator C. The connecting ports can be connected to the external interfaces through the flow channels within the flow channel plate or through external connecting pipes. In this technical solution, the first connecting port 024 is connected to the valve port of the valve component 3 through the flow channel in the flow channel plate, the second connecting port 025 is connected to the inlet of the radiator C, and the third connecting port 026 is connected to the first pump 51. It can be understood that fluids entering the first flow channel 231 from the first connecting port 024, fluids entering the first flow channel 231 from the second connecting port 025, and fluids entering the first flow channel 231 from the replenishment channel 023 can all enter the third connecting port 026 for circulation in a certain mode of the system. The flow channel plate assembly 2 includes a first diverter plate 272 and a second diverter plate 273. The first diverter plate 272 and the second diverter plate 273 are located in the first flow channel 231. The first exhaust channel 021 and the replenishment channel 023 are located on both sides of the first diverter plate 272, and the second exhaust channel 022 and the replenishment channel 023 are located on both sides of the second diverter plate 273. Specifically, the first diverter plate 272 and the second diverter plate 273 are arranged side by side, dividing part of the first flow channel 231 into a first exhaust channel 021, a second exhaust channel 022, and a replenishment channel 023. One end of the first diverter plate 272 is connected to the wall forming the first flow channel 231, and the other end of the first diverter plate 272 extends toward the first connecting port 024 and is spaced apart from the wall forming the first connecting port 024. One end of the first diverter plate 272 extends to the inner cavity of the replenishment port 25 and is fixedly connected to the wall forming the replenishment port 25. The other end extends to the first connecting port 024. That is, the liquid entering from the first connecting port 024 is diverted by the first diverter plate 272. Because the density of gas is low, the fluid entering the first exhaust channel 021 carries air bubbles and enters the water jug ​​8 through the first exhaust port 821. After gas-liquid separation in the water jug ​​8, the liquid enters the first flow channel 231 through the outlet 823 and the replenishment channel 023. Similarly, one end of the second diverter plate 273 is connected to the wall forming the first flow channel 231, and one end of the second diverter plate 273 extends toward the second connection port 025 and is spaced apart from the wall forming the second connection port 025.One end of the second diverter plate 273 extends into the inner cavity of the liquid inlet 25 and is fixedly connected to the wall forming the liquid inlet 25. The other end extends to the second connecting port 025. That is, the liquid entering from the second connecting port 025 is diverted by the first diverter plate 272. Due to the low density of gas, the fluid entering the second exhaust channel 022 carries air bubbles and enters the water jug ​​8 through the second exhaust port 822. After gas-liquid separation in the water jug ​​8, the fluid enters the first flow channel 231 through the liquid outlet 823 and the liquid inlet channel 023. Figure 11 , 12 The replenishment port 25 includes a first port 251, a second port 252, and a third port 253. A portion of the first diversion plate 272 is fixedly connected to the wall forming the replenishment port 25, and a portion of the second diversion plate 273 is fixedly connected to the wall forming the replenishment port 25. The first port 251 and the third port 253 are located on both sides of the first diversion plate 272, and the third port 253 and the second port 252 are located on both sides of the first diversion plate 272. The first port 251 is connected to the first exhaust channel 021 and the first exhaust port 821, the second port 252 is connected to the second exhaust channel 022 and the second exhaust port 822, and the third port 253 is connected to the liquid outlet 823 and the replenishment channel 023. The first diverter plate 272 and the second diverter plate 273 divide the liquid inlet 25 into a first port 251, a second port 252, and a third port 253. The first port 251, the second port 252, and the third port 253 are located in the same position on the flow channel plate assembly 2. The liquid inlet 25 of the flow channel plate assembly 2 is correspondingly set and sealed to the connection port 082 of the water bottle 8. That is, one port realizes the functions of liquid inlet and two venting ports. The structure is relatively simple and easy to assemble. The first exhaust channel 021, the liquid replenishment channel 023, and the second exhaust channel 022 within the first flow channel 231 are not connected after the flow is split. Correspondingly, the connecting part 81 of the kettle 8 includes a first partition 83 and a second partition 84. The first partition 83 and the second partition 84 are located within the connecting port 082. The first exhaust port 821 and the liquid outlet 823 are located on both sides of the first partition 83, and the second exhaust port 822 and the liquid outlet 823 are located on both sides of the first partition 83. A portion of the first flow divider 272 is opposite to and sealed to the first partition 83, and a portion of the second flow divider 273 is opposite to and sealed to the second partition 84. The fluid entering the kettle 8 through the first exhaust port 821 and the second exhaust port 822 undergoes gas-liquid separation within the kettle 8 before being discharged through the liquid outlet 823. In this technical solution, the kettle 8 and the flow channel plate assembly 2 adopt a separate structure, which is beneficial for subsequent maintenance, and the structure of the separate kettle 8 and the flow channel plate assembly 2 is relatively simple.

[0043] Along the direction of gravity, the replenishment port 25 is positioned higher than the first connecting port 024 and the second connecting port 025, and the third connecting port 026 is positioned lower than the first connecting port 024 and the second connecting port 025, with the first connecting port 024 and the second connecting port 025 located on opposite sides of the replenishment port 25; the first diverter plate 272 includes a first section 2721 and a second section 2722, with the second section 2722 positioned closer to the first connecting port 024 than the first section 2721, and the first section 2721 and the second section 2722 being positioned at an angle; the second diverter plate 273 includes a third section 2731 and a fourth section 2732, with the fourth section 2732 positioned closer to the second connecting port 025 than the third section 2731, and the third section 2732 being positioned closer to the second connecting port 025 than the third section 2731, and the third section 2732 being positioned closer to the second connecting port 025, and the third section 2732 being positioned closer to the second connecting port 025 than the third section 2732 ... 1 is set at an angle to the fourth section 2732; the first flow channel 231 includes a first sub-flow channel 2311, a second sub-flow channel 2312, and a third sub-flow channel 2313. The first sub-flow channel 2311 is located on one side of the first section 2721, the second sub-flow channel 2312 is located on one side of the third section 2731, the third sub-flow channel 2313 connects the first sub-flow channel 2311 and the third connecting port 026, the third sub-flow channel 2313 connects the second sub-flow channel 2312 and the third connecting port 026, and the third sub-flow channel 2313 connects the replenishment flow channel and the third connecting port 026. The flow area of ​​the first sub-flow channel 2311 is larger than the area of ​​the first exhaust channel 021, and the flow area of ​​the second sub-flow channel 2312 is larger than the area of ​​the second exhaust channel 022. The first flow divider 272 and the second flow divider 273 are arranged in an L-shape along the direction of gravity. The liquid inlet 25 is located at the top, and the first connecting port 024 and the second connecting port 025 are located on both sides, which is conducive to the arrangement of the external interface on the flow channel plate assembly 2. The third connecting port 026 is relatively lower and is connected to the water pump to provide power for the flow of fluid. This layout optimizes the flow channel layout of the flow channel plate assembly 2 and is conducive to the miniaturization of the flow channel plate assembly 2 to a certain extent. The first thermal management module has a first exhaust path, a second exhaust path, and a liquid replenishment path. Fluid entering from the first connection port 024 enters the water tank 8 via the first exhaust path, undergoes gas-liquid separation within the water tank 8, and then enters the third connection port 026 via the gas replenishment path to participate in the first loop circulation. The other part of the fluid enters directly from the first sub-channel 2311 into the third connection port 026 to participate in the first loop circulation. Fluid entering from the second connection port 025 enters the water tank 8 via the second exhaust path, undergoes gas-liquid separation within the water tank 8, and then enters the third connection port 026 via the gas replenishment path to participate in the first loop circulation. The other part of the fluid enters directly from the second sub-channel 2312 into the third connection port 026 to participate in the first loop circulation.

[0044] The specific structure of the kettle 8 includes a connecting part 81, and a connecting port 082 that communicates with the flow channel plate assembly 2 is located in the connecting part 81. The connecting part 81 is fixedly connected to the assembly part 20 of the flow channel plate assembly 2. In this technical solution, the connecting part 81 is threadedly connected to the assembly part 20. The connecting part 81 also includes a connecting port 082 connected to the connecting part 81. The connecting port 082 includes a first vent 821, a second vent 822, and a liquid outlet 823. The first vent 821, the second vent 822, and the liquid outlet 823 are all connected to the inner cavity of the kettle 8. That is, the connecting port 082 is divided into a first vent 821, a second vent 822, and a liquid outlet 823. Specifically, the connecting part 81 includes a first partition 83 and a second partition 84. The first partition 83 and the second partition 84 are located within the connecting port 082. The first vent 821 and the liquid outlet 823 are located on both sides of the first partition 83, and the second vent 822 and the liquid outlet 823 are located on both sides of the first partition 83. The kettle 8 includes multiple partitions that divide the kettle 8 into several chambers. The kettle 8 includes a first chamber 861, a second chamber 862, and a third chamber 863. The first chamber 861 communicates with the first vent 821, the second chamber 862 communicates with the second vent 822, and the third chamber 863 communicates with the liquid outlet 823. Figure 16 As shown, the fluid flows through the first chamber 861 and the second chamber 862 into the kettle 8. The fluid flows away from the connection port 082, passing through the chambers in the kettle 8. An opening is provided on the partition plate, and the direction of fluid flow is changed according to the position of the opening on the partition plate. During the flow of fluid in the kettle 8, air bubbles rise to the top of the kettle 8. The longer the fluid flow path, the better for venting. Finally, the two streams of fluid are discharged from the outlet 823 into the flow channel plate assembly 2. The kettle 8 in this technical solution has a simple structure, eliminating the need for a separate venting channel 26 in the kettle 8, and only one connection port 082 is required. The assembly of the kettle 8 and the flow channel plate assembly 2 is relatively simple.

[0045] The flow channel plate assembly 2 includes a first plate 27 and a second plate 28, which are fixedly connected. In this technical solution, at least one of the first plate 27 and the second plate 28 has a groove. The first plate 27 and the second plate 28 are fixedly connected. The wall forming the first flow channel 231 includes the wall forming the groove. The wall forming the first exhaust channel 021 includes a portion of the wall forming the first flow channel 231 and a portion of the first diverter plate 272. The wall forming the second exhaust channel 022 includes a portion of the wall forming the first flow channel 231 and a portion of the second diverter plate 273. The wall forming the liquid replenishment channel 023 includes a portion of the wall forming the first flow channel 231, a portion of the first diverter plate 272, and a portion of the second diverter plate 273. The liquid replenishment port 25 is located on the first plate 27. The first diverter plate 272 and the second diverter plate 273 are located on at least one of the first plate 27 and the second plate 28. The first diversion plate 272, the second diversion plate 273, the first plate 27, and / or the second plate 28 are injection molded as a single unit, resulting in a relatively simple structure.

[0046] The flow channel plate assembly 2 includes multiple flow channels, which are connected to components other than the thermal management module. The connection relationship of the flow channels is switched by the control of the valve component 3 to realize different thermal management system modes. The thermal management module includes a fluid pump 50 and the valve component 3. The flow channel plate assembly 2 includes a mounting cavity, at least part of which is located in the mounting cavity and fixedly connected to the flow channel plate assembly 2. The first connection port 024 and the second connection port 025 are connected to the external interface on the flow channel plate assembly 2. The external interface on the flow channel plate assembly 2 includes an external interface connected to the valve component 3 and an external interface connected to other thermal management components. The third connection port 026 is connected to the mounting cavity, that is, the third connection port 026 is connected to the fluid pump 50. The thermal management module includes multiple external interfaces. The number of external interfaces is related to the thermal management mode. In this embodiment, the thermal management module includes a first external interface 01, a second external interface 02, a third external interface 03, a fourth external interface 04, a fifth external interface 05, a sixth external interface 06, a seventh external interface 07, and an eighth external interface 08. The first external interface 01 is located on the first heat exchanger 1, and the remaining external interfaces are located on the flow channel plate assembly 2. Some of the external interfaces are connected to the valve port of the valve component 3 through the flow channels in the flow channel plate assembly 2. The rotation of the valve core in channel 26 enables the connection of different flow channels. Some external interfaces are connected to other thermal management components. Each thermal management component is individually connected to two of the external interfaces, or the thermal management components are connected in series and then connected to the external interfaces. That is, each thermal management component can form a loop for circulation independently, or they can be connected in series to form a loop. Other thermal management components include a motor B, a battery A, a radiator C, and a heater core D.

[0047] like Figure 19As shown, a detailed description of one of the thermal management systems is provided. The thermal management system includes the aforementioned thermal management module, battery A, motor B, radiator C, and heater core D. Battery A is connected to the first external interface 01 and the second external interface 02. Motor B is connected to the third external interface 03 and the fourth external interface 04. Radiator C is connected to the fifth external interface 05 and the sixth external interface 06. Heater core D is connected to the seventh external interface 07 and the eighth external interface 08. The thermal management module includes a first valve component 31 and a second valve component 32. The fluid pump 50 includes a first pump 51, a second pump 52, and a third pump 53. The first valve component 31 includes a first valve port 311, a second valve port 312, a third valve port 313, a fourth valve port 314, and a fifth valve port 315. The second valve component 32 includes a sixth valve port 321, a seventh valve port 322, an eighth valve port 323, a ninth valve port 324, and a tenth valve port 325. The second external interface 02 is connected to the eighth external interface 07 of the second valve component 32. Valve port 323 is connected to the second pump 52, which is connected to the ninth valve port 324 of the second valve component 32 and the third valve port 313 of the first valve component 31. The third external interface 03 is connected to the seventh valve port 322. The first pump 51 is connected to the fourth external interface 04, which is connected to the sixth valve port 321. The fifth external interface 05 is connected to the sixth valve port 321, and the sixth external interface 06 is connected to the tenth valve port 325. The third pump 53 is connected to the fourth valve port 314, which is connected to the eighth external interface 08, and the fifth valve port 315 is connected to the seventh external interface 07. It should be noted that the above external interfaces, pumps, and valve components are all connected through the flow channel of the flow channel plate assembly 2. By switching the connection relationships of the valve ports of the first valve component 31 and the second valve component 32, different circuits can be formed. For example, when the seventh valve port 322 and the sixth valve port 321 are connected, the motor B and the first pump 51 form at least part of the first circuit; when the eighth valve port 323 and the ninth valve port 324 are connected, and the third valve port 313 and the second valve port 312 are connected, the battery A and the second pump 52 form at least part of the second circuit; when the fourth valve port 314 and the fifth valve port 315 are connected, the heater core D and the third pump 53 form at least part of the third circuit. Of course, in other modes, at least two of the first, second, and third circuits can be connected in series to form a large circuit, which will not be described in detail here.

[0048] During the venting and replenishment process of the thermal management module, the first connection port 024 is connected to one of the valve ports of valve component 3, the second connection port 025 is connected to the outlet of radiator C, and the inlet of radiator C is connected to the second valve port of the second valve component 32. In this thermal management system, the first connection port 024 is connected to the sixth valve port 321 of the second valve component 32, and the inlet of radiator C is connected to the tenth valve port 325 of the second valve component 32. Both the first connection port 024 and the second connection port 025 are connected to the first pump 51. The outlet of the first pump 51 is connected to the inlet of motor B, and the outlet of motor B is connected to the third valve port of valve component 3, that is, to the seventh valve port 322 of the second valve component 32. Motor B can form a first loop in series with the first pump 51 and radiator C, and motor B can form a first sub-loop with the first pump 51. The motor B, fluid pump 50, and radiator C are connected in series to form a first loop, or the motor B and fluid pump 50 form a first sub-loop. In both the first loop and first sub-loop operating modes, the thermal management module can vent air from the flow channels within the flow channel plate assembly 2. Specifically, the thermal management system includes a first operating mode and a second operating mode. In the first operating mode, the sixth valve port 321 and the seventh valve port 322 are connected, and the motor B and the first pump 51 form a first sub-loop to vent air from the thermal management module. In the second operating mode, the seventh valve port 322 and the tenth valve port 325 are connected, and the motor B, radiator C, and the first pump 51 form a first loop to cool the motor B while simultaneously venting air from the thermal management module. Of course, in addition to the above-mentioned replenishment and venting modes, in this thermal management system, as long as the circulation loop involving the motor B—that is, the mode where at least one of the first loop, second loop, or third loop is connected in series—the thermal management module can be replenished with liquid and vented.

[0049] This thermal management system can cool or heat battery A alone, cool motor B alone, or cool or heat battery A and motor B in series. It heats the passenger cabin through the heater core D. Different modes can be achieved depending on the different connection relationships of the valve ports, which will not be described in detail here.

[0050] It should be noted that the above technical solutions are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above technical solutions, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present invention. All technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the present invention.
