[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0024] This application provides a thermal management device 100, which can be applied to a thermal management system. The thermal management system can be used in household air conditioners, automotive air conditioners, energy storage systems, etc.

[0025] like Figures 1-14 As shown, this application provides a thermal management device 100, including a first flow channel plate 1, a heat exchanger 2, a filter assembly 3, a valve component 4, a first sealing element 5, and a second flow channel plate 6. One end of the second flow channel plate 6 is fixedly connected to or limited to the first flow channel plate 1, for example, by welding or threaded connection. In this application, the specific connection method between one end of the second flow channel plate 6 and the first flow channel plate 1 is a threaded connection. The other end of the second flow channel plate 6 is fixedly connected to or limited to the heat exchanger 2. In this application, the other end of the second flow channel plate 6 is fixed to the heat exchanger 2 by a threaded connection. The threaded fixed connection method can facilitate multiple disassembly and assembly, which is beneficial for subsequent maintenance and replacement. The second flow channel plate 6 has a through hole 106, through which a portion of the heat exchanger 2 passes and is sealed to the first flow channel plate 1. This sealing connection can be achieved through welding, threaded connections, etc. In this application, the portion of the heat exchanger 2 is connected to the first flow channel plate 1 by a first sealing element 5. In some embodiments, the first sealing element 5 is fitted onto the peripheral wall of a portion of the heat exchanger 2, or the first sealing element 5 is fixedly or partially connected to the heat exchanger 2, further ensuring the sealing performance between the heat exchanger 2 and the first flow channel plate 1. In this embodiment, the first sealing element 5 is an O-ring. O-rings are standard parts, facilitating replacement and maintenance, and to some extent, saving costs. Of course, in other embodiments, the first sealing element 5 can also be a rectangular sealing ring, a gasket, etc.

[0026] like Figure 4As shown, the heat exchanger 2 includes a main body 22 and an interface 21. The main body 22 and the interface 21 are separate structures. The main body 22 and the interface 21 are fixedly connected or limitedly connected, for example, by welding or threading. In this application, the main body 22 and the interface 21 are fixed by welding to further ensure the sealing between them. The interface 21 has a first groove 211 and a second groove 212. The second groove 212 is away from the filter assembly 3 relative to the first groove 211. The first groove 211 opens towards the outer peripheral wall of the interface 21. At least part of the first seal 5 is located in the first groove 211. The first seal 5 partially seals against the first flow channel plate 1 to ensure the sealing between the first flow channel plate 1 and the heat exchanger 2, which is beneficial to the stable operation of the thermal management device 100. At the same time, the first groove 211 helps to prevent the first seal 5 from falling off or shifting when installing or removing the filter assembly 3, thus preventing leakage. Of course, in other specific embodiments, the first sealing member 5 can also be provided at the end of the interface portion 21, and the first sealing member 5 abuts against the end face of the first flow channel plate 1 for sealing. The second groove 212 opens toward the outer peripheral wall of the interface portion 21. The second groove 212 is close to the welding connection between the interface portion 21 and the main body portion 22, which helps to prevent the molten metal from flowing to non-target areas (such as weld edges) due to gravity or surface tension during the welding process, and helps to ensure the quality of the weld formation.

[0027] like Figure 6 and Figures 7-10As shown, the first flow channel plate 1 has a first mounting cavity 101, a second mounting cavity 102, a first flow channel 103, a second flow channel 104, and a first hole 107. The first hole 107 is located on the peripheral wall forming the first mounting cavity 101 and connects the first mounting cavity 101 and the first flow channel 103. In other specific embodiments, other methods can also be used to connect the first mounting cavity 101 and the first flow channel 103. For example, a through hole can be opened on the first mounting cavity 101 and a through hole can be opened on the wall forming the first flow channel 103, using a hollow part for connection. The first flow channel 103 connects the first mounting cavity 101 and the second mounting cavity 102. At least a portion of the valve component 4 is located in the second mounting cavity 102. The valve component 4 is fixedly connected to or limited by the first flow channel plate 1, for example, by welding or threaded connection. In this application, the valve component 4 is fixed to the first flow channel plate 1 by a threaded connection. Threaded connection facilitates later maintenance, troubleshooting, and replacement or adjustment of the valve component 4. Simultaneously, the connection between the valve component 4 and the first flow channel plate 1 must be sealed to prevent leakage, which helps ensure the stable operation of the thermal management device 100. The valve component 4 has multiple functions, such as throttling and pressure reduction, and flow regulation. Sensing elements can also be installed on the peripheral wall forming the first flow channel 103 to monitor the pressure, flow rate, temperature, and other data of the medium in the first flow channel 103 in real time, which helps ensure the safe, stable, and efficient operation of the thermal management device 100. The first flow channel plate 1 includes a first mounting portion 11. A wall portion forming a first mounting cavity 101 is located within the first mounting portion 11. The filter assembly 3 is located within the first mounting cavity 101. The wall forming the first mounting cavity 101 guides the installation of the filter assembly 3. The filter assembly 3 is detachably connected to the first mounting portion 11, for example, by a threaded connection, snap-fit ​​connection, or flange connection. In this application, the filter assembly 3 is fixed to the first mounting portion 11 by a threaded connection. This threaded connection facilitates disassembly of the filter assembly 3 and makes subsequent maintenance more convenient. In this application, the second flow channel 104 connects the first mounting cavity 101 and the channel within the heat exchanger 2. The fluid from the heat exchanger 2 enters the first mounting cavity 101 through the second flow channel 104 and is filtered by the filter assembly 3 to remove impurities. This helps prevent impurities from entering the first flow channel 103 and the second mounting cavity 102, ensuring the stable operation of the valve component 4. Furthermore, the detachable connection between the filter assembly 3 and the first mounting portion 11 facilitates subsequent maintenance and further reduces the cost of parts replacement.

[0028] The first flow channel plate 1 has a third mounting cavity 105. A second flow channel 104 connects the third mounting cavity 105 and the first mounting cavity 101. The opening of the first mounting cavity 101 and the opening of the third mounting cavity 105 are located on different sides of the first flow channel plate 1. The first flow channel plate 1 includes a second mounting portion 12. The wall portion forming the third mounting cavity 105 is located in the second mounting portion 12. The portion of the heat exchanger 2 is sealed to the wall forming the third mounting cavity 105. The opening of the first mounting cavity 101 and the opening of the third mounting cavity 105 are located on different sides of the first flow channel plate 1. This layout facilitates the assembly of the first flow channel plate 1 with the filter assembly 3 and the heat exchanger 2, and helps to make the structure of the thermal management device 100 more compact.

[0029] like Figure 6 As shown, a first plane is defined, which is perpendicular to the thickness direction of the first flow channel plate 1. Along the thickness direction of the first flow channel plate 1, the projection of the wall forming the first mounting cavity 101 onto the first plane at least partially coincides with the projection of the wall forming the third mounting cavity 105 onto the first plane. The medium flows from the third mounting cavity 105 into the first mounting cavity 101. This indicates that the walls forming the first mounting cavity 101 and the third mounting cavity 105 are partially aligned, which reduces flow resistance pressure. In this application, the first mounting cavity 101 and the third mounting cavity 105 are coaxially arranged along the thickness direction of the first flow channel plate 1, indicating that the first mounting cavity 101 and the third mounting cavity 105 are connected, forming a straight channel. The straight channel maintains a stable flow direction, and the pressure gradient in the straight channel is gentler, avoiding local high-pressure or low-pressure areas caused by sudden turns or cross-sectional changes, which helps reduce flow resistance pressure and also facilitates assembly with the heat exchanger 2. Of course, in some other embodiments, the opening of the first mounting cavity 101 may also be located on one side of the first flow channel plate 1 with the opening of the third mounting cavity 105, indicating that the first mounting cavity 101 and the third mounting cavity 105 are connected to form a curved connection. The curved path can flexibly bypass obstacles, which is beneficial to improving the utilization of space.

[0030] In this application, the wall forming the second flow channel 104 is located between the wall forming the first mounting cavity 101 and the wall forming the third mounting cavity 105. The second flow channel 104 connects the first mounting cavity 101 and the third mounting cavity 105. The first sealing member 5 abuts against the wall forming the third mounting cavity 105 for sealing, or the first sealing member 5 abuts against the end of the opening of the third mounting cavity 105 for sealing, thereby ensuring the sealing between the heat exchanger 2 and the first flow channel plate 1. Figure 6As shown, the circumferential diameter of the wall forming the second flow channel 104 is smaller than the circumferential diameter of the wall forming the third mounting cavity 105. Therefore, a stepped portion 108 is formed between the wall forming the second flow channel 104, the wall forming the third mounting cavity 105, and the wall forming the first mounting cavity 101. The first limiting portion 108a is located on the side wall of the stepped portion 108, that is, on the portion of the wall forming the third mounting cavity 105. In this embodiment, the interface portion 21 of the heat exchanger 2 is at least partially located in the third mounting cavity 105. The interface portion 21 is sealed to the wall forming the third mounting cavity 105, and the interface portion 21 communicates with the channel inside the heat exchanger 2. Furthermore, the first sealing member 5 is sleeved on the first groove 211 of the interface portion 21. The first sealing member 5 radially abuts against the wall forming the third mounting cavity 105 for sealing. This radial sealing method is beneficial for a compact structure and space saving.

[0031] In some embodiments, at least a portion of the interface portion 21 of the heat exchanger 2 is located in the third mounting cavity 105. The first seal 5 may also be located at the end of the interface portion 21 facing the filter assembly 3. The first seal 5 has an annular structure and a through hole that connects the second flow channel 104 and the channel within the heat exchanger 2. In this embodiment, the first seal 5 is fixedly connected or limitedly connected to the interface portion 21, for example, by vulcanization, bonding, or welding. The first seal 5 abuts against the first limiting portion 108a for sealing. This end-face sealing method helps reduce wear on the first seal 5, increases its service life, and reduces costs to some extent. In some embodiments, the first seal 5 may also be located at the end of the interface portion 21 of the heat exchanger 2 facing the filter assembly 3. The first seal 5 has an annular structure and a through hole that connects the second flow channel 104 and the channel within the heat exchanger 2. In this embodiment, the first sealing element 5 is fixedly connected or limited to the interface portion 21, for example, by vulcanization, bonding, or welding. The end of the first sealing element 5 abuts against the opening of the third mounting cavity 105 for sealing. The end-face sealing method results in a large contact area between the first sealing element 5 and the first flow channel plate 1, which is beneficial to ensuring the sealing performance between the heat exchanger 2 and the first flow channel plate 1.

[0032] like Figure 6 and Figures 11-14As shown, the opening of the filter assembly 3 faces the heat exchanger 2. The flow through the heat exchanger 2 reaches the filter assembly 3. Impurities in the fluid are filtered by the filter assembly 3 and will adhere to the filter screen. Subsequently, under the vibration of the whole vehicle, they will fall off due to gravity, which helps to reduce flow resistance and further extend the service life of the filter assembly 3. The filter assembly 3 includes a first part 31 and a second part 32. Along the thickness direction of the first flow channel plate 1, the first part 31 is farther away from the heat exchanger 2 than the second part 32. The first part 31 and the second part 32 are an integral structure, meaning that the first part 31 and the second part 32 can be manufactured using 3D printing or injection molding processes. Of course, the first part 31 and the second part 32 can also be separate structures, fixed by a fixed connection or limiting connection method, such as welding, bonding, or snap-fit ​​connection. In this application, the first part 31 and the second part 32 are separate structures, and the first part 31 and the second part 32 are fixed by a snap-fit ​​connection. This separate assembly method is beneficial to improving the utilization rate of parts, facilitating the replacement of some parts in the future, and further facilitating later maintenance. At the same time, disassembling the parts also helps to reduce the processing difficulty of individual parts, further reducing processing costs to a certain extent. When the second part 32 needs to be replaced due to excessive impurity accumulation, the filter assembly 3 can be removed from the first flow channel plate 1, and only the second part 32 needs to be replaced, reducing the waste of parts. At least a portion of the first part 31 is detachably connected to the first mounting part 11. In this application, a portion of the first part 31 is fixed to the first mounting part 11 by a threaded connection. The threaded connection facilitates disassembly, making subsequent maintenance more convenient and further reducing the replacement cost of parts. At least a portion of the second part 32 is sealed to the wall forming the second flow channel 104.

[0033] The first part 31 includes a limiting groove 301, which opens towards the second part 32. The limiting groove 301 includes a guide surface 301a, a stop surface 301b, and a U-shaped surface 301c. The guide surface 301a and the stop surface 301b are connected to form a "7"-shaped limiting structure. The second part 32 includes an elastic locking part 321, which is elastic. The elastic locking part 321 includes an insertion part 321a and a second limiting part 321b. The insertion part and the second limiting part 321b are integral structures. The second limiting part 321b protrudes relative to the insertion part 321a in a direction perpendicular to the thickness of the first flow channel plate 1. During assembly, the insertion part 321a of the elastic locking part 201 is inserted along the opening of the limiting groove 301. The elastic locking part 321 undergoes elastic deformation and enters the limiting groove 301 along the guide surface 301a, and then recovers its deformation. Along the thickness direction of the first flow channel plate 1, such as Figure 13As shown, under the influence of gravity, the second part 32 has the second limiting part 321b abutting against the stop surface 301b, and the elastic locking part 321 engaging with the limiting groove 301. A gap is left between the elastic locking part 321b and the U-shaped surface 301c of the limiting groove 301, which can compensate for the processing error of the second part 32 along the thickness direction of the first flow channel plate 1. At the same time, maintaining this gap can also prevent the second part 32 from rotating when the first part 31 is installed and fixed to the first flow channel plate 1, thus preventing wear on the second part 32. This is beneficial to protecting the elastic locking part 321 of the second part 32 and preventing breakage.

[0034] The first part 31 includes a first fixing part 311 and a first sealing part 312. The first fixing part 311 and the first sealing part 312 are integral structures. The first fixing part 311 is located away from the heat exchanger 2 relative to the first sealing part 312. The first mounting part 11 includes a first sidewall part 112 and a second sidewall part 113. The first sidewall part 112 is located away from the heat exchanger 2 relative to the second sidewall part 113. The first sealing part 312 and the second sidewall part 113 are sealed together. The first sidewall part 112 has threads and is threadedly connected to the first fixing part 311. The filter assembly 3 includes a second sealing element 33. In this application, the second sealing element 33 is an O-ring. The O-ring is a standard part, which is convenient for replacement and maintenance, and to a certain extent helps to save costs. The second sealing element 33 is sleeved on the first sealing part 312. The first sealing part 312 has a third groove 312a, which opens towards the outer peripheral wall of the first sealing part 312. The first fixing part 311 is away from the heat exchanger 2 relative to the third groove 312a. At least part of the second sealing element 33 is located in the third groove 312a. The second sealing element 33 abuts against the second side wall part 113 for sealing. The setting of the third groove 312a helps to prevent the second sealing element 33 from falling off or shifting when installing or disassembling the filter assembly 3, further ensuring the sealing between the filter assembly 3 and the first flow channel plate 1 and preventing leakage. The end of the first part 31 that is relatively far from the second part 32 has an internal hexagonal groove. The setting of the internal hexagonal groove facilitates the installation and disassembly of the filter assembly 3. At the same time, the setting of the internal hexagonal groove helps to allow the filter assembly 3 to be fully installed in the first mounting cavity 101, saving a certain amount of space and contributing to a compact structure.

[0035] The second part 32 includes a filter part 322 and a second sealing part 323. In this application, the elastic snap-fit ​​part 321, the filter part 322 and the second sealing part 323 are integral structures, injection molded, which simplifies the processing steps. The integral injection molding has no seams or connection points, improving the overall durability of the filter assembly 3. The second sealing part 323 is away from the elastic snap-fit ​​part 321 relative to the filter part 322. The filter part 322 is clearance-fitted with the wall forming the first mounting cavity 101 to prevent the distance between the filter part 322 and the peripheral wall forming the first mounting cavity 101 from being too small. The first hole 107 is located on the peripheral wall forming the first mounting cavity 101. The first hole 107 is partially blocked by the filter part 322, which causes the fluid to be unable to flow into the first flow channel 103 or reduces the flow rate of the fluid, affecting the stable operation of the thermal management device 100. The second sealing part 323 is sealed to the wall forming the second flow channel 104. In this application, the second sealing part 323 protrudes relative to the filter part 322 along the vertical direction of the thickness of the first flow channel plate 1, and the second sealing part 323 abuts against the wall forming the second flow channel 104 for sealing. Of course, in other embodiments, the filter assembly 3 includes a third sealing element (not shown), and the second sealing part 323 includes a fourth groove (not shown). The fourth groove opens toward the outer peripheral wall of the second sealing part 323, and the third sealing element is sleeved on the second sealing part, that is, at least part of the third sealing element is located in the fourth groove. The third sealing element abuts against the wall forming the second flow channel for sealing. The fourth groove helps to prevent the third sealing element from falling off or shifting when installing and removing the filter assembly 3, further ensuring the sealing performance between the filter assembly 3 and the first flow channel plate 1. It also ensures that the fluid flowing through the heat exchanger 2 is filtered by the filter assembly 3 before flowing into the first flow channel 103.

[0036] The above examples illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the technical solution and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of this utility model.
