Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] See Figure 1 and Figure 2One embodiment of the present invention provides a thermal management component that can be used in the thermal management system of a vehicle. Specifically, it can be used on the refrigerant side of the thermal management system, or in other words, the working medium flowing in the thermal management component is refrigerant. Of course, it can also be used on the coolant side of the thermal management system, that is, the working medium flowing in the thermal management component is coolant. The following is a detailed description.

[0020] refer to Figures 1-5 One embodiment of this application provides a thermal management assembly, including a first plate 1, a second plate 3, and a third plate 2. At least the first plate 1 is formed by stamping. The second plate 3 and the third plate 2 can be formed by stamping, extrusion, or machining. The second plate 3 is fixedly connected to one side of the first plate 1, and the third plate 2 is fixedly connected to the other side of the first plate 1. The fixed connection is preferably welded, but screws or other fixing methods are also possible, as long as the fixing method can achieve a seal between the plates. The thermal management assembly has a flow channel 10 and a liquid storage cavity 20. Along the thickness direction of the first plate 1, at least a portion of the flow channel 10 is located on one side of the first plate 1, and at least a portion of the liquid storage cavity 20 is located on the other side of the first plate 1, forming the flow channel 10. The wall portion forming the liquid storage cavity 20 is located on one side of the first plate 1, the wall portion forming the liquid storage cavity 20 is located on the other side of the first plate 1, the wall portion forming the liquid storage cavity 20 is located on the side of the second plate 3 near the first plate 1, and the wall portion forming the flow channel 10 is located on the side of the third plate 2 near the first plate 1. In this embodiment, there are multiple flow channels 10, and multiple flow channels 10 are located between the first plate 1 and the third plate 2. The first plate 1 and the third plate 2 together define the flow channel 10. The liquid storage cavity 20 is located between the first plate 1 and the second plate 3. The first plate 1 and the second plate 3 together define the liquid storage cavity 20. It should be noted that the liquid storage cavity 20 is not limited to the liquid storage cavity of the liquid storage device, but can also be the gas separation cavity of the gas-liquid separator, or a cavity that has both gas separation function and liquid storage function.

[0021] refer to Figure 3In this embodiment, in order to improve the compactness of the flow channel and the liquid storage cavity, it is preferable that the flow channel 10 and the liquid storage cavity 20 are arranged along the thickness direction of the first plate 1. That is, along the thickness direction of the first plate 1, the projection of the wall forming the flow channel 10 overlaps with the projection of the wall forming the liquid storage cavity 20. Further, in this embodiment, the first plate 1 has a first wall 111 and a second wall 113. The first wall 111 and the second wall 113 are arranged opposite to each other. That is, the second wall 113 is located on the back side of the first wall 111 corresponding to the first protrusion 11. The wall forming the flow channel 10 includes the first wall 111, and the wall forming the liquid storage cavity 20 includes the second wall 113. This arrangement not only improves the compactness of the entire thermal management assembly, but also, since the first plate 1 is formed by stamping, the first plate 1 has a thin plate structure as a whole. The flow channel 10 and the liquid storage chamber 20 are arranged on opposite sides of the first plate 1, and the refrigerant in the flow channel 10 and the refrigerant in the liquid storage chamber 20 can exchange heat, especially through the walls at the first wall 111 and the second wall 113. This provides conditions for further rationally arranging the flow channel 10 to make its heat exchange more favorable.

[0022] Along the thickness direction perpendicular to the first plate 1, the projection of the first wall 111 overlaps with the projection of the second wall 113. The first wall 111 and the second wall 113 serve as the wall of the flow channel 10 and the wall of the liquid reservoir, respectively. Along the thickness direction of the first plate 1, the projection of the wall forming the flow channel 10 overlaps with the projection of the wall forming the liquid reservoir 20, which can further improve the heat exchange efficiency between the fluid in the flow channel 10 and the fluid in the liquid reservoir 20.

[0023] Specifically, refer to Figure 3In this embodiment, the first plate 1 includes a first base 101 and a first protrusion 11. The first protrusion 11 is stamped relative to the first base 101 and protrudes towards the second plate 3 relative to the first base 101. The first wall 111 is located on the side of the first protrusion 11 near the third plate 2, and the second wall 113 is located on the side of the first protrusion 11 near the second plate 3. The wall surface of the first base 101 near the liquid storage cavity 20 is defined as the first surface 101a, and the wall surface of the first base 101 near the flow channel 10 is defined as the second surface 101b. The first wall 111 protrudes relative to the first surface 101a, and the second wall 113 is recessed relative to the second surface 101b. In this embodiment, the protruding first wall 111 forms part of the wall of the liquid storage cavity 20, and the recessed second wall 113 forms part of the wall of the flow channel 10. The flow channel 10 extends along the thickness direction of the first plate 1 into the area where the original liquid storage cavity 20 is located. This makes the entire thermal management assembly more compact in the thickness direction of the first plate 1. On the other hand, the space of the liquid storage cavity can partially surround the flow channel, which is more conducive to the heat exchange of the refrigerant in the flow channel 10 and the liquid storage cavity 20. The first protrusion 11 is similar to an arc-shaped structure, and the first wall... 111 and the second wall 113 are located on both sides of the arc-shaped structure. The arc-shaped structure can increase the heat exchange area between the fluid in the flow channel 10 and the fluid in the liquid storage cavity 20, which is beneficial to realize the heat exchange between the two fluids. Of course, in other embodiments, a protrusion opposite to the stamping direction of the first protrusion 11 can also be provided on the first plate 1. That is, the protrusion protrudes towards the third plate 2 relative to the first base 101, and the protrusion is located near the first protrusion 11. This can further improve the heat exchange efficiency of the refrigerant in the flow channel 10 and the liquid storage cavity 20.

[0024] refer to Figure 3 and Figure 4 In this embodiment, the second plate 3 can also be a stamped part. The second plate 3 includes an edge portion 103 and a protrusion 102. The protrusion 102 is stamped relative to the edge portion 103. The protrusion 102 protrudes away from the first plate 1 compared to the edge portion 103. The wall portion forming the liquid storage cavity 20 is located in the protrusion 102. The edge portion 103 is sealed to the first base 101. Preferably, the edge portion is welded to the first base. Welding the edge portion to the first base can seal the peripheral edge of the liquid storage cavity 20. In this embodiment, the second plate 3 is also stamped. On the one hand, less material is used and the process is simple, which can reduce processing costs. On the other hand, the stamped second plate 3 has a thin-walled structure and is lighter, which can make the entire thermal management component lighter. Furthermore, see Figure 3 The stamped second plate 3 occupies less space in the thickness direction of the first plate 1, that is, the second plate 3 has a flat structure, which can improve the compactness of the entire thermal management assembly.

[0025] refer to Figure 1 and Figure 2 In some embodiments, the liquid storage chamber 20 serves as the gas separation chamber of a gas-liquid separator. A flow guiding component is provided in the liquid storage chamber 20, similar to the U-shaped tube in a traditional gas-liquid separator. The difference from a traditional gas-liquid separator is that part of the structure of the flow guiding component in this application can be integrated with the first plate 1, the second plate 3, or the third plate 2, which can reduce the process installation steps and thus reduce the processing cost. Specifically, the thermal management component has a flow guiding channel 30, and part of the wall forming the flow guiding channel 30 is integrated with the first plate 1, the second plate 3, or the third plate 2.

[0026] Further, refer to Figure 4 and Figure 5 In this embodiment, the first plate 1 has a second protrusion 12, which protrudes towards the second plate 3 relative to the first base 101. The wall portion forming the flow channel 30 is located on one side of the second protrusion 12, and the wall portion forming the liquid storage cavity 20 is located on the other side of the second protrusion 12. The first base 101 is welded and fixed to the third plate 2, and the wall portion forming the flow channel 30 is located on the third plate 2. That is, the first protrusion 11 and the second protrusion 12 are stamped on the first plate 1, and the third plate 2 is welded and fixed to the first plate 1 so that the third plate 2 closes the opening of the first protrusion 11 and the opening of the second protrusion 12, thereby forming the flow channel 10 and the flow channel 30. Compared with the traditional U-shaped tube, the formation of the flow channel 30 is simple to manufacture and the cost is reduced.

[0027] refer to Figures 2-5In this embodiment, the thermal management component further includes a flow channel 30, a flow outlet 34, an oil return hole 33, and a flow inlet 32. Along the direction of gravity, the oil return hole 33 is lower than the flow inlet 32 ​​and the flow outlet 34. Along the fluid path of the flow channel 30, the oil return hole 33 is located between the flow inlet 32 ​​and the flow outlet 34. The gas-liquid inlet 31 connects the liquid storage chamber 20 and the flow channel 10. The flow inlet 32 ​​connects the liquid storage chamber 20 and the flow channel 30. The flow outlet 34... The flow channel 30 is connected to the other side of the flow outlet 34, which is connected to the inlet of the compressor 54. The oil return hole 33 connects the flow channel 30 and the liquid storage chamber 20. The flow inlet 32 ​​and the oil return hole 33 are located on the second protrusion 12, and the flow outlet 34 is located on the third plate 2. In addition, the thermal management component also has a pressure relief hole 35, which is located on the second protrusion 12 and is opposite to the flow outlet 34. The pressure relief hole 35 connects the flow channel 30 and the liquid storage chamber 20. In this embodiment, the wall of the flow channel 30 is U-shaped. The flow inlet 32 ​​and the flow outlet 34 are located at the two ends above the U-shaped structure, and the oil return hole 33 is located at the turning point below the U-shaped structure. Further, in this embodiment, the second protrusion 12 includes a first bottom wall 301 and a first side wall 302. The first bottom wall 301 is away from the first base 101 relative to the first side wall 302. There is a gap between the first bottom wall 301 and the second plate 3. The flow inlet 32, the oil return hole 33 and the pressure relief hole 35 are all located on the first bottom wall 301. The third plate 2 has a flow guide wall 303. The flow guide wall 303 is disposed opposite to the first bottom wall 301. The wall forming the flow guide channel 30 includes the flow guide wall 303. The flow outlet 34 is located on the flow guide wall 303. The gas-liquid inlet 31 is located on the first plate 1. The central axis direction of the gas-liquid inlet 31 is consistent with the central axis direction of the flow guide inlet 32. The opening direction of the gas-liquid inlet 31 and the opening direction of the flow guide inlet 32 ​​are both facing the second plate 3. The gas-liquid inlet 31 and the guide inlet 32 ​​have the same opening orientation and are both opposite to the second plate 3. This allows the liquid refrigerant entering the liquid storage chamber 20 from the gas-liquid inlet 31 to be sprayed onto the second plate 3 and dispersed on the second plate 3, thus preventing the liquid refrigerant from directly entering the guide inlet 32.

[0028] In this embodiment, reference Figure 5The aforementioned thermal management assembly includes a filter assembly 41, which has a filter mesh 40 that connects the oil return hole 33 to the liquid storage chamber 20. The filter assembly 41 is located between the first bottom wall 301 and the second plate 3. One end of the filter assembly 41 is welded to the first bottom wall 301, and the other end is welded to the second plate 3. During the forming process, both ends of the entire filter assembly 41 are coated with flux, allowing it to be placed between the first plate 1 and the second plate 3 and positioned at the oil return hole 33. It can then be furnace-welded together with the first plate 1, the second plate 3, and the third plate 2. The process is simple. Furthermore, since the second plate 3 is also a thin-walled structure formed by stamping, the filter assembly 41 can serve to fix and connect the first plate 1 and the second plate 3, preventing deformation of the second plate 3 under refrigerant pressure and improving the pressure resistance of the entire thermal management assembly.

[0029] In addition, in this embodiment, the first wall 111 of the first protrusion 11 is welded and fixed to the second plate 3. Specifically, the first wall 111 of the first protrusion 11 is welded to the protrusion 102. The protrusion 102 of the liquid storage cavity 20 is fixed by the first protrusion 11 of the flow channel 10 punched out by the first plate 1. When the protrusion 102 of the liquid storage cavity 20 is deformed away from the first plate 1 by the refrigerant pressure in the cavity, it pulls the first protrusion 11 of the first plate 1 to prevent the protrusion 102 from deforming, thereby increasing the pressure resistance of the entire thermal management assembly. Reference Figures 6-8 Furthermore, a third protrusion 13 can also be provided on the second plate. The third protrusion 13 is stamped relative to the protrusion 102 and protrudes towards the first plate 1 relative to the protrusion 102. The third protrusion 13 is welded and fixed to the first base 101, and the first protrusion 11 is welded and fixed to the protrusion 102. The third protrusion 13 and the first protrusion 11 also have the ability to strengthen the deformation resistance of the protrusion 102, thereby increasing the pressure resistance of the entire thermal management assembly.

[0030] refer to Figure 1 and Figure 11 In some embodiments, when the liquid storage chamber 20 serves as the gas separation chamber of the gas-liquid separator, the thermal management component also includes a liquid distribution section 110. The liquid distribution section 110 can prevent fluid from directly entering the guide inlet 32 ​​from the gas-liquid inlet 31. The liquid distribution section 110 is integrally structured with the first plate 1 or the second plate 3. Compared with the traditional gas-liquid separator, which first manufactures the liquid distribution structure of the cylinder separately and then assembles it, the structure of this application is simpler and facilitates the manufacturing of the entire thermal management component.

[0031] refer to Figures 6-8In this embodiment of the application, the liquid dispersing function is achieved by the first protrusion 11. At least one of the first plate 1 and the second plate 3 has a stamped protrusion 11'. The protrusion 11' protrudes toward the liquid storage cavity 20. The liquid dispersing part 110 includes a first wall 111. The first wall 111 is located on the side of the protrusion 11' near the liquid storage cavity 20. The first wall 111 can prevent fluid from directly entering the guide inlet 32 ​​from the gas-liquid inlet 31. The protrusion 11' includes a first protrusion 11 and a third protrusion 13. Similarly, the position of the protrusion 11' can be varied. It can be that the protrusion 11' is only provided on the second plate 3, i.e., the aforementioned second protrusion 12, and the third protrusion 13 of the second plate 3 protrudes towards the first plate 1 relative to the protrusion 102, with the first wall 111 located on the side of the third protrusion 13 closer to the first plate 1. Alternatively, it can be that the protrusion 11' is only provided on the first plate 1, i.e., the aforementioned first protrusion 11, with the first protrusion 11 protruding towards the second plate 3 relative to the first base 101, and the first protrusion 11 including a second wall 113, the second wall 113 being adjacent to the first wall 111. The back is set, and the wall forming the flow channel 10 includes a second wall 113. In addition, there can be protrusions 11' on both the first plate 1 and the second plate 3. On the one hand, the protrusions 11' with the liquid dispersing function are formed by stamping on the first plate 1 and / or the second plate 3, which does not require the additional liquid dispersing cup as in traditional gas-liquid separators. The structure and forming process are simpler. On the other hand, some of the protrusions 11' not only have the liquid dispersing function, but also serve as the wall forming the flow channel in the thermal management component. It can be understood that the liquid dispersing structure is formed at the same time when the flow channel is stamped, which eliminates the need for multiple forming processes, saves process steps, and reduces costs.

[0032] Furthermore, at least one of the first plate 1 and the second plate 3 has a third wall 112, which is welded and fixed to the first wall 111. The welded and fixed third wall 112 and the first wall 111 are located on the first plate 1 and the second plate 3, respectively. The protrusion 11' connects the first plate 1 and the second plate 3, which allows the liquid refrigerant to circulate around the peripheral wall of the first protrusion 11 in the liquid storage cavity 20. The extension direction of the protrusion 11' is irregular and there are many of them, which can play a sufficient role in liquid dispersion.

[0033] Based on the above embodiments, in order to better prevent fluid from directly entering the guide inlet 32 ​​from the gas-liquid inlet 31, the liquid distribution section 110 is at least partially located between the gas-liquid inlet 31 and the guide inlet 32 ​​along the line connecting the gas-liquid inlet 31 and the guide inlet 32, and the projection of the wall forming the gas-liquid inlet 31 overlaps with the projection of the liquid distribution section 110. Specifically, in this embodiment, the projection of a portion of the first wall 111 of the liquid distribution section 110 overlaps with the wall forming the gas-liquid inlet 31, and / or, the projection of the first wall 111 of the liquid distribution section 110 also overlaps with the wall forming the guide inlet 32. With at least a portion of the liquid distribution section 110 located between the gas-liquid inlet 31 and the guide inlet 32, the liquid distribution section 110 can prevent liquid refrigerant from directly entering the guide inlet 32 ​​from the gas-liquid inlet 31.

[0034] refer to Figure 11 In this embodiment, the liquid dispersing part 110 includes a plurality of stamped protrusions 11', including a first protrusion 11 and a third protrusion 13. For a single protrusion 11', the direction of the line connecting the gas-liquid inlet 31 and the guide inlet 32 ​​is defined as the first direction. Perpendicular to the first direction, part of the protrusion 11' is located on one side of the line connecting the gas-liquid inlet 31 and the guide inlet 32, and part of the protrusion 11' is located on the other side of the line connecting the gas-liquid inlet 31 and the guide inlet 32. For the plurality of protrusions 11', perpendicular to the first direction, part of the protrusions 11' is located on one side of the line connecting the gas-liquid inlet 31 and the guide inlet 32, and part of the protrusions 11' is located on the other side of the line connecting the gas-liquid inlet 31 and the guide inlet 32.

[0035] Specifically, in this embodiment, along a direction perpendicular to the first direction, the first protrusion 11 is partially located on one side of the line connecting the gas-liquid inlet 31 and the guide inlet 32, and the first protrusion 11 is partially located on the other side of the line connecting the gas-liquid inlet 31 and the guide inlet 32. In this way, the first protrusion 11 can prevent liquid refrigerant from directly entering the guide inlet 32 ​​from the gas-liquid inlet 31. When the gas-liquid refrigerant enters the liquid storage chamber 20 from the gas-liquid inlet 31, it impacts the protrusion 102 and is refracted onto the protrusion 11', especially onto the first protrusion 11, which can exchange heat with the fluid in the flow channel where the first protrusion 11 is located, which is beneficial to improving the thermal efficiency of the entire thermal management component.

[0036] Furthermore, in this embodiment, in order to ensure sufficient heat exchange between the refrigerant in the liquid storage chamber 20 and the first protrusion 11 of the liquid distribution section 110, a plane perpendicular to the thickness direction of the first plate 1 is defined as the first plane. Some of the first protrusions 11 intersect the first direction along the extension direction of the first plane. Perpendicular to the first direction, at least one part of the first protrusion 11 is located on one side of the line connecting the gas-liquid inlet 31 and the guide inlet 32, and another part of the first protrusion 11 is located on the other side of the line connecting the gas-liquid inlet 31 and the guide inlet 32. This arrangement of the first protrusions can lengthen the path of the refrigerant from the gas-liquid inlet 31 to the guide inlet 32, and enable sufficient heat exchange between the refrigerant in the liquid storage chamber 20 and the first protrusion 11 of the liquid distribution section 110.

[0037] refer to Figure 10 The flow channel 10 of the thermal management component is optimized to ensure that the heat exchange between the fluid in the flow channel 10 and the fluid in the liquid storage chamber 20 is as favorable as possible to the thermal management system. Since the liquid storage chamber 20 is the gas-liquid storage chamber of the gas-liquid separator, the fluid in the liquid storage chamber 20 is a low-temperature, low-pressure gas from the evaporator 522, mixed with a certain amount of liquid refrigerant, and gas-liquid separation occurs in the liquid storage chamber 20. Therefore, considering the arrangement of the flow channel 10 in the entire thermal management system, the flow channel located from the compressor outlet to the refrigerant inlet of the condenser in the thermal management system is defined as the high-pressure flow channel 01, and the flow channel located from the refrigerant outlet of the condenser to the refrigerant inlet of the expansion valve in the thermal management system is defined as the medium-pressure flow channel. In this embodiment, the flow channel 10 includes the high-pressure flow channel 01 and the medium-pressure flow channel 02. Along the thickness direction of the first plate 1, at least part of the projection of the wall forming the medium-pressure flow channel 02 overlaps with the projection of the wall forming the liquid storage chamber 20, while the projection of the wall forming the high-pressure flow channel 01 is separated from the projection of the wall forming the liquid storage chamber 20. The high-temperature, high-pressure fluid upstream of condenser 521 is used for sufficient heat exchange with the coolant in condenser 521, carrying heat to various parts of the thermal management system through the coolant. It is not suitable for heat exchange with the low-temperature refrigerant in the gas-liquid separator. Therefore, in this embodiment, only the wall of the medium-pressure flow channel 02 is arranged on the back side of the wall of the liquid storage chamber 20, while the wall of the high-pressure flow channel 01 is arranged far away from the liquid storage chamber 20. In this way, the medium-temperature, high-pressure refrigerant exiting condenser 521 can exchange heat with the low-temperature, low-pressure refrigerant in the liquid storage chamber 20. The low-temperature, low-pressure refrigerant in the liquid storage chamber 20 absorbs heat, increasing the superheat of the gaseous refrigerant and raising the suction temperature of compressor 54. Simultaneously, the subcooling of the medium-temperature refrigerant in the medium-pressure flow channel 02 increases, reducing the temperature before the expansion valve, thereby improving heat exchange performance and optimizing the heat pipe system circulation.

[0038] Furthermore, it is preferable to minimize the participation of low-temperature, low-pressure saturated refrigerant after the expansion valve in heat exchange; otherwise, the heat exchange performance of the evaporator 522 will be reduced, and the optimization effect will not be significant. Therefore, in some embodiments, the flow channel from the refrigerant outlet of the expansion valve to the refrigerant inlet of the evaporator in the thermal management system is defined as a low-pressure, medium-temperature flow channel, and the flow channel from the refrigerant outlet of the evaporator to the refrigerant inlet of the gas-liquid separator in the thermal management system is defined as a low-pressure, low-temperature flow channel. Flow channel 10 includes a low-pressure, medium-temperature flow channel 031 and a low-pressure, low-temperature flow channel 032.
