Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments are described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0020] refer to Figures 1 to 3This application provides a compressor assembly for a vehicle's thermal management system. The compressor assembly includes a compressor 1, a flow channel assembly 2, and a support frame 3. The flow channel assembly 2 has a refrigerant flow channel 100 and at least a portion of a first plate 21 and a second plate 22 formed from sheet metal. At least one of the first plate 21 and the second plate 22 is stamped to form a first protrusion 221. A portion of the wall of the refrigerant flow channel 100 is located at the first protrusion 221. The refrigerant flow channel 100 is in fluid communication with the compressor 1. A first connecting portion 11 and a second connecting portion 12 are provided on the cylinder of the compressor 1. The first connecting portion 11 is fixedly connected to or limits the support frame 3, and the second connecting portion 12 is fixedly connected to or limits the flow channel assembly 2. In this embodiment, the second connecting portion 12 is directly fixedly connected to the first plate 21. In other embodiments, the second connecting portion can also be indirectly fixed to the first plate 21 through other components. In addition, the support frame 3 is used for fixed connection with the vehicle frame. Specifically, for the first protrusion 221, the flow channel assembly 2 includes a first plate 21, a second plate 22, and a connector 23. The first plate 21, the second plate 22, and the connector 23 are fixedly connected, preferably by welding. At least one of the first plate 21 and the second plate 22 has the first protrusion 221. The first protrusion 221 is formed by stamping. The thickness of the plate with the first protrusion 221 in the first plate 21 and the second plate 22 is between 1.5mm and 3.5mm. The stamping process of the plate in this thickness range is simple, and the pressure resistance performance also meets the pressure resistance requirements of refrigerant flow. In this embodiment, both the first plate 21 and the second plate 22 are formed by stamping. Compared with the plates formed by machining, forging, and casting, the stamped plates are thinner, use less material, are lighter, have a simpler process, and are lower in cost, and can meet the pressure resistance requirements of refrigerant flow. The first plate 21 and the second plate 22 in the flow channel assembly 2 are processed into plates, which can reduce the weight of the entire flow channel assembly. On the one hand, the compressor cylinder body supports the flow channel assembly more stably. On the other hand, the overall weight of the compressor 1 and the flow channel assembly 2 is reduced, and the support frame 3 supports its components with greater stability.

[0021] refer to Figure 4 and Figure 5In this embodiment, the first connecting part 11 and the second connecting part 12 are located on different sides of the compressor 1 around its circumference. Specifically, the flow channel assembly 2 is located on one side of the compressor 1, and the thickness direction of the flow channel assembly 2 is perpendicular to the direction of gravity and perpendicular to the axial direction of the compressor 1. The support frame 3 is located below the compressor 1 along the direction of gravity, and the support frame 3 extends and spreads out approximately along the horizontal plane. The compressor assembly includes a shock-absorbing pad 34, and the support frame 3 includes a mounting part 33. The shock-absorbing pad 34 is fixedly connected to or limited by the mounting part 33, and the shock-absorbing pad 34 is fixedly connected to or limited by the frame. Along the direction of gravity, the support frame 3 is located below the compressor 1, and at least part of the orthographic projection of the mounting part 33 is located around the orthographic projection of the compressor 1. By setting the support frame 3, the mounting parts 33 used to connect the shock-absorbing pad 34 can be arranged more reasonably, so that the overall weight of the compressor 1 and the flow channel assembly 2 is more evenly distributed on each shock-absorbing pad 34, improving the stability of the entire compressor assembly connected to the frame.

[0022] Further, see reference Figure 5 and Figure 8 Regarding the design of the support frame 3, since the flow channel assembly 2 has a certain weight and various fluid management components need to be connected on the flow channel assembly 2, the compressor 1 side will be heavier. Therefore, the design places part of the mounting part 33 on the side of the flow channel assembly 2 away from the compressor 1, which can better support the overall weight of the compressor 1 and the flow channel assembly 2 and improve the stability of the compressor assembly connection. Specifically, along the horizontal direction, the flow channel assembly 2 is located on the side of the compressor 1. The support frame 3 includes a main body 31 and an extension 32. The mounting part 33 includes a first mounting part 331. The extension 32 connects the main body 31 and the first mounting part 331. The extension 32 extends towards the flow channel assembly 2 relative to the main body 31. At least part of the first mounting part 331 is located on the side of the flow channel assembly 2 away from the compressor 1.

[0023] The first connecting portion 11 includes a plurality of first legs 111 extending along the direction of gravity, and the second connecting portion 12 includes a plurality of second legs 121 extending along the horizontal direction. The first legs 111, the second legs 121, and a portion of the compressor 1 housing are integrally formed, specifically integrally cast. Along the direction of gravity, at least a portion of the orthographic projection of the first legs 111 is located on the periphery of the orthographic projection of the compressor 1 housing, or at least a portion of the first legs 111 protrudes relative to the compressor 1 housing in a direction perpendicular to gravity; and / or, along the horizontal direction, at least a portion of the orthographic projection of the second legs 121 is located on the periphery of the orthographic projection of the compressor 1 housing, or at least a portion of the second legs 121 protrudes relative to the compressor 1 housing in a direction perpendicular to gravity. The first legs 111 and the second legs 121 are distributed as widely as possible on the outer periphery of the compressor housing, which is beneficial to improving the connection stability of the entire assembly.

[0024] refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 The first connecting part 11 of the compressor 1 is fixedly connected to the support frame 3 by fasteners 9, and the second connecting part 12 of the compressor 1 is fixedly connected to the flow channel assembly 2 by fasteners 9. Specifically, the first connecting part 11 includes a plurality of first legs 111 extending in the direction of gravity, and the second connecting part 12 includes a plurality of second legs 121 extending in the horizontal direction. The first legs 111, the second legs 121 and part of the housing of the compressor 1 are integrally structured. The first legs 111 have a first connecting hole 1110 with an opening facing the support frame 3, and the second legs 121 have a second connecting hole 1210 with an opening facing the flow channel assembly 2. The fasteners 9 are partially located in the first connecting hole 1110 and the second connecting hole 1210. The support frame 3 has a first through hole 30, the flow channel assembly 2 has a second through hole 10, and the compressor assembly includes fasteners 9. The fasteners 9 pass through the first through hole 30 to fasten the first legs 111 to the support frame 3, and the fasteners 9 pass through the first through hole 30 to fasten the second legs 121 to the flow channel assembly 2. The fasteners 9 used to connect the compressor 1 and the support frame 3 are installed and tightened from the side of the support frame 3 away from the compressor 1. The fasteners 9 used to connect the compressor 1 and the flow channel assembly 2 are installed and tightened from the side of the flow channel assembly 2 away from the compressor 1. The installation space of the fasteners should be avoided as much as possible within the boundary of the compressor assembly. On the one hand, the installation of the fasteners on the production line is more convenient. On the other hand, the compressor assembly can be more compact.

[0025] refer to Figure 12 In some embodiments, to ensure a more compact overall compressor assembly, the connector 23 includes a first recess 235 having a first profiled cavity 2350 recessed in a direction away from the compressor 1, wherein a portion of the compressor 1 housing located in or near the opening of the first profiled cavity 2350 is shaped to fit the first recess 235; and / or, the support frame 3 includes a second recess 35 having a second profiled cavity 350 recessed in a direction away from the compressor 1, wherein a portion of the compressor 1 housing located in or near the opening of the second profiled cavity 350 is shaped to fit the second recess 35. In this embodiment, both the first recess 235 and the second recess 35 are arc-shaped recesses. The arc-shaped walls of the first recess 235 and the second recess 35 are matched with the arc-shaped wall of the cylinder of the compressor 1. In other words, the arc-shaped walls of the first recess 235 and the second recess 35 are set approximately concentrically with the arc-shaped wall of the cylinder of the compressor 1. In this way, while ensuring that the installation is not interfered with, the flow channel assembly 2 and the support frame 3 can be closer to the compressor 1, and the structure of the entire compressor assembly is more compact.

[0026] refer to Figure 1The compressor assembly also includes a refrigerant valve 6, a heat exchanger 4, and a liquid receiver 5. The refrigerant valve 6, heat exchanger 4, and liquid receiver 5 are all fixedly connected or limited to the flow channel assembly 2. Since the heat exchanger 4 and liquid receiver 5 are relatively large, they are arranged on the side of the flow channel assembly 2 away from the compressor 1. The refrigerant valve 6 is relatively small, and it is arranged on the side of the flow channel assembly 2 closer to the compressor 1. The refrigerant valve 6 is arranged by inserting it into the remaining space after the compressor 1 and the flow channel assembly 2 are connected. Of course, the refrigerant valve 6 can also be arranged by inserting it into multiple heat exchangers 4 and liquid receivers 5. In this way, the arrangement of the fluid management components on the entire compressor assembly is more reasonable and more compact.

[0027] refer to Figure 4 and Figure 6 In this embodiment, the flow channel assembly 2 includes a first plate 21 and a second plate 22. A first protrusion 221 is located on the second plate 22. The first plate 21 and the second plate 22 are welded and fixed together. The wall forming the refrigerant flow channel 100 is located on the first plate 21 and the second plate 22. In other words, the edge of the first protrusion 221 is welded and fixed to the first plate 21 to form a portion of the refrigerant flow channel. At least one of the first plate 21 and the second plate 22 is fixedly connected to the compressor 1. The compressor assembly includes a heat exchanger 4. The heat exchanger 4 includes a plurality of plates 41. The plurality of plates 41 are stacked with the first plate 21 and the second plate 22. The plurality of plates 41, the first plate 21 and the second plate 22 are integrally furnace welded and fixed together. Integrated welding refers to the process of assembling multiple plates 41, the first plate 21, and the second plate 22 into a whole using tooling and then brazing them in a furnace. Compared to connecting each component separately, integrated welding is not only easier to manufacture, but also reduces leakage points, has higher space utilization, and lower costs. In addition, integrated welding makes the entire component connection more stable, which is beneficial to improving its robustness.

[0028] The flow channel assembly 2 also includes a connector 23, which is welded and fixed to the first plate. The connector is located on the side of the first plate closer to the compressor. In this embodiment, the connector is formed by casting, forging, or machining. The connector has a thicker wall, higher strength, and heavier weight. Therefore, fixing it on the side closer to the compressor makes the center of gravity of the overall assembly of the compressor and the flow channel assembly more reasonable, which is beneficial to the connection stability of the entire assembly and improves the robustness of the assembly. In this embodiment, the multiple plates 41 of the heat exchanger 4, the connecting blocks of the liquid reservoir 5, the first plate 21, the second plate 22, the connector 23, and some connecting blocks used to connect the sensors are fixed together by tooling and then brazed together in a furnace. Of course, in other embodiments, some of the above components can also be welded and fixed by other welding methods or by other connection methods, such as screw fixing.

[0029] refer to Figure 8 and Figure 9 In this embodiment, the compressor assembly includes a mounting bracket 51, which is fixedly connected to or limits the connection of the liquid reservoir 5. The second connecting portion 12 has a second connecting hole 1210, the flow channel assembly 2 has a second through hole 10, and the mounting bracket 51 has a third through hole 510. The openings of the second connecting hole 1210, the second through hole 10, and the third through hole 510 are at least partially aligned. The compressor assembly includes a fastener 9, which is partially located in the third through hole 510, partially in the second through hole 10, and partially in the second connecting hole 1210. The fastener 9 fixes the mounting bracket 51 and the flow channel assembly 2 to the second connecting portion 12. The mounting bracket 51 of the liquid reservoir 5 shares a second support leg 121 with the flow channel assembly 2 and is locked to the housing of the compressor 1 by a screw, which reduces the number of fasteners and the fastener installation steps. In addition, the liquid reservoir 5 is fixed to the housing of the compressor 1 by the mounting bracket 51, which is more stable than being fixed to a stamped plate alone.

[0030] refer to Figure 10 and Figure 11The connector 23 has a first flow channel portion 231, a second flow channel portion 232, a third flow channel portion 233, and a connecting rib 234. The first flow channel portion 231, the second flow channel portion 232, the third flow channel portion 233, and the connecting rib 234 are integrally formed. The refrigerant flow channel 100 includes a first flow channel 2310, a second flow channel 2320, and a third flow channel 2330. A portion of the wall of the first flow channel 2310 is located in the first flow channel portion 231, a portion of the wall of the second flow channel 2320 is located in the second flow channel portion 232, and a portion of the wall of the third flow channel 2330 is located in the third flow channel portion 233. The connecting rib 234 directly or indirectly connects the first flow channel 231 and the second flow channel 232. In this embodiment, the third flow channel 233 is located between the first flow channel 231 and the second flow channel 232. The connecting rib 234 connects the first flow channel 231 and the third flow channel 233. The connecting rib connects the second flow channel 232 and the third flow channel 233. There are hollow grooves 230 between the first flow channel 231 and the third flow channel 233, and between the second flow channel 232 and the third flow channel 233. The wall forming the hollow groove 230 includes the connecting rib 234. For connector 23, since the flow channel assembly 2 is not used to bear the weight of the entire compressor assembly, its structural strength requirement is not high. Considering that the first plate 21 and the second plate 22 formed by stamping are prone to deformation or slightly weak strength when laminated and welded, the first flow channel part 231, the second flow channel part 232 and the third flow channel part 233 of connector 23 are forged, cast or extruded, and the connector has high strength. The three flow channel parts are connected into a whole by connecting ribs 234, covering a large area of ​​the stamping plate, which can prevent the stamping plate from deforming in the high temperature environment of furnace welding. On the other hand, it also improves the overall strength of the flow channel assembly 2, which improves the connection stability between the flow channel assembly 2 and the compressor 1 and improves the robustness of the entire compressor assembly. In addition, in this embodiment, low-temperature refrigerant, high-temperature refrigerant, and medium-temperature refrigerant flow in the first flow channel 2310, the second flow channel 2320, and the third flow channel 2330, respectively. Specifically, the inlet channel 2010 connects the first flow channel 2310 to the air inlet of the compressor 1 inlet connection 101, and the outlet channel 2020 connects the second flow channel 2320 to the exhaust port of the compressor 1 outlet connection 102. The low-temperature refrigerant returning to the compressor from the system flows in the first flow channel 2310, the high-temperature refrigerant discharged from the compressor flows in the second flow channel 2320, and the refrigerant after being throttled by the expansion valve flows in the third flow channel 2330, the temperature of which is between the former two. Therefore, in order to avoid harmful heat exchange in the three flow channels, hollow grooves are provided for heat insulation to improve the heat exchange efficiency of the entire compressor assembly.

[0031] refer to Figure 3 , Figure 4 and Figure 6In this embodiment, the compressor 1 includes an inlet connection portion 101 and an outlet connection portion 102. The inlet connection portion 101 has an inlet port communicating with the refrigerant flow channel 100, and the outlet connection portion 102 has an outlet port communicating with the refrigerant flow channel 100. The flow channel assembly 2 includes a first interface portion 201 and a second interface portion 202. The inlet connection portion 101 is in fluid communication with the first interface portion 201, and the outlet connection portion 102 is in fluid communication with the second interface portion 202. The connection between the inlet connection portion 101 and the first interface portion 201 is sealed, and the connection between the outlet connection portion 102 and the second interface portion 202 is sealed. The first interface portion 201 and the second interface portion 202 are located on the connector 23. Since the first plate 21 and the second plate 22 are formed by sheet metal processing, specifically by stamping, the stamped plate has thin walls and low strength. It is easy to deform under the high temperature of welding and fixing. When connected with the compressor inlet connection 101 and outlet connection 102, the positional accuracy is poor and leakage is easy to occur. Therefore, the strength of the first plate 21 and the second plate 22 is strengthened by the connector 23 to prevent the first plate 21 and the second plate 22 from deforming at high temperature, thus ensuring the positional accuracy tolerance requirements of the connection between the compressor and the flow channel assembly and ensuring the sealing performance of the compressor 1 and the flow channel assembly 2 at the connection.

[0032] Furthermore, both the first interface portion 201 and the second interface portion 202 are located on the connector 23. The first interface portion 201 and the second interface portion 202 are integrally structured and located on the forged, machined, or forged connector 23. The connector 23 has a thicker wall and higher strength, which can further ensure the relative positional tolerance of the two interface portions that mate with the compressor's intake and exhaust ports, and ensure the sealing performance of the compressor 1 and the flow channel assembly 2 at the connection. In this embodiment, both the first interface portion 201 and the second interface portion 202 are configured to convex towards the compressor. The inlet and outlet connection portions of the compressor have interface cavities 1001 that can receive the first interface portion 201 and the second interface portion 202. The first interface portion 201 and the second interface portion 202 are respectively inserted and fixed to the inlet and outlet connection portions of the compressor, wherein the sealing method adopts a double O-ring radial seal.

[0033] refer to Figure 10 and Figure 11 The second connecting part 12 of the compressor 1 is fixedly connected to the first plate 21 in the flow channel assembly 2. The first plate 21 is basically a flat plate, which is beneficial for the design of the dimensions of each second support leg 121 of the second connecting part 12. In some other embodiments, in order to ensure the connection strength between the compressor 1 and the flow channel assembly 2, some connection points are set on the stronger connecting member 23. Specifically, refer to Figure 11The connector 23 includes a fixing part 236, which is fixedly connected to the compressor 1. The fixing part 236 is located around the first interface 201 and / or around the second interface 202. The fixing part 236 on the connector 23 not only improves the stability and strength of the connection between the compressor 1 and the flow channel assembly 2, but also, by placing the fixing part 236 near the first interface 201 and / or the second interface 202, ensures the stability of the connection between the compressor inlet / outlet connection and the first and second interfaces, preventing compressor vibration from affecting the seal at the connection between the compressor 1 and the flow channel assembly 2, thereby improving the sealing performance of the compressor assembly.

[0034] Specifically, the first plate 21 has a second through hole 10, the fixing part 236 has a fourth through hole 2360, and the compressor 1 has a second connecting hole 1210. The openings of the second through hole 10, the fourth through hole 2360, and the second connecting hole 1210 are at least partially opposite to each other. The first plate 21 and the fixing part 236 are fixedly connected to the compressor 1 by fasteners 9. The fasteners 9 are partially located in the second through hole 10, partially in the fourth through hole 2360, and partially in the second connecting hole 1210. Similarly, connecting the first plate 21 and the connector 23 by fasteners 9 can further strengthen the connection between the first plate 21 and the connector 23 and enhance the pressure resistance of the internal flow channel.

[0035] In this embodiment, to further ensure the positional fit between the interface portion and the inlet / outlet connection portion, the first interface portion 201 and / or the second interface portion 202 both include a straight portion 300 and a protruding tube portion 200. The protruding tube portion 200 protrudes relative to the straight portion 300. The inlet connection portion 101 and the outlet connection portion 102 have an interface cavity 1001. The protruding tube portion 200 is located in the interface cavity 1001. The end face of the corresponding inlet connection portion 101 and / or outlet connection portion 102 near the flow channel assembly 2 abuts against the corresponding straight portion 300. In this embodiment, the flatness of the straight portion can be ensured by processing and forming. The abutment between the end face of the inlet / outlet connection portion and the straight portion can ensure the coaxiality between the interface cavity 1001 and the protruding tube portion 200, thereby ensuring the positional fit between the two interface portions and the inlet / outlet connection portion.

The description of these embodiments is merely for the purpose of helping to understand the technical solution and core ideas of this utility model. It should be pointed out 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.
