Description

Technical Field

[0001] This utility model relates to a thermal management system, and more particularly to an integrated thermal management system. Background Technology

[0003] With the development of new energy vehicles, the market has placed higher demands on their internal thermal management systems (including air conditioners and refrigerators) in terms of energy efficiency and stability. An existing new energy vehicle thermal management system integrates heat pump technology. It uses a water-cooled LCC (liquid cooler) as the condenser of the original thermal management system and a water-cooled chiller as the evaporator. By intelligently controlling the circulation path of the refrigerant and coolant, it achieves efficient cooling, heating, and energy recovery, making it particularly suitable for electric vehicles and hybrid vehicles.

[0004] In existing thermal management systems, designers often directly use black-box compressors, requiring them to connect and locate the corresponding pipelines to the compressor's intake and exhaust ports before considering pipeline design and layout. This results in complex pipeline layouts that are not easy to install.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

[0044] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0045] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustration only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.

[0046] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0047] Please see Figure 1-5 This embodiment of the integrated thermal management system includes a compressor 1, a water cooler 2, and a refrigerator 4. The integrated thermal management system further includes a flow channel plate 6 fixedly disposed on the compressor 1. The flow channel plate 6 is used to connect at least two of the compressor 1, the water cooler 2, and the refrigerator 4.

[0048] Specifically, the compressor 1 has an exhaust port 11 and an intake port 12; the water cooler 2 includes a water cooler inlet 21 and a water cooler outlet 22; the refrigerator 4 includes a refrigerator inlet 41 and a refrigerator outlet 42; this embodiment also includes a gas-liquid separator 5 disposed downstream of the refrigerator 4 for realizing gas-liquid separation, the gas-liquid separator 5 includes a separator inlet 51 and a separator outlet 52.

[0049] In this embodiment, the flow channel plate 6 forms independent first channels 61, second channels, third channels 62, and fourth channels 63. The exhaust port 11 is directly connected to the inlet of the water cooler 2; the water cooler outlet 21 is connected to the expansion valve 3 through the first channel 61; the expansion valve 3 is connected to the cooler inlet 41 through the second channel; the cooler outlet 42 is connected to the separator inlet 51 through the third channel 62; and the separator outlet 52 is connected to the suction port 12 through the fourth channel 63.

[0050] With the above structure, a flow channel plate 6 can be installed on one side of the compressor 1, and the gas-liquid separator 5, the refrigerator 4, and the water cooler 2 can be connected in series in the refrigerant circulation of the thermal management system through the flow channel plate 6. This results in high integration and ease of installation. Specifically, this embodiment provides a flow channel plate 6 with multiple independent channels. The original pipelines that required connecting wires can be connected in series in the entire thermal management system through the corresponding integrated channels of the flow channel plate 6. Therefore, unified management of most pipelines can be achieved. The flow channel plate 6 is pre-designed and molded, integrating all pipelines on a unified thin plate, which has stronger leak-proof performance than ordinary pipeline connections.

[0051] Secondly, in this application, the compressor 1 is used as the center of gravity to directly fix the flow channel plate 6. Other components are directly fixed through the compressor 1 or fixed with the help of the flow channel plate 6, forming a stable connection relationship and a high degree of integration.

[0052] Based on the above embodiments, the compressor 1 has a preset center of mass, and the center of mass of the refrigerator 2 and the water cooler 4 as a whole is close to or located on the vertical plane of the preset center of mass. In this invention, the installation positions of the water cooler 2 and the refrigerator 4, as functional components, can be adjusted based on the preset center of mass of the compressor 1, thereby reducing vibration and abnormal noise caused by the center of mass shift during the operation of the compressor 1 when the compressor 1 is directly bearing the force. Specifically, this invention uses the compressor 1 as the center of gravity to balance the positions of the refrigerator 4 and the water cooler 2, which are larger in volume and weight, making them closer to the center of mass of the compressor 1, minimizing the impact of the compressor's center of mass shift, and making the compressor 1 more stable in operation.

[0053] The following are examples of several different assembly methods, all of which utilize a flow channel plate to integrate 6 pairs of pipelines, achieving a highly integrated design centered on the compressor:

[0054] Example 1

[0055] Please see Figure 1-5In this embodiment, one of the water cooler 2 and the refrigerator 4 is suspended on the side of the flow channel plate 6 facing the preset center of mass. Specifically, the flow channel plate 6 has a first side and a second side arranged opposite to each other. The compressor 1, water cooler 2, expansion valve 3, refrigerator 4, and gas-liquid separator 5 are fitted onto the first side or the second side of the flow channel plate 6. Independent first channels 61, second channels, third channels 62, and fourth channels 63 are formed inside the flow channel plate 6. The exhaust port 11 is connected to the inlet of the water cooler 2. The water cooler outlet 21 is connected to the expansion valve 3 through the first channel 61. The expansion valve 3 is connected to the refrigerator inlet 41 through the second channel. The refrigerator outlet 42 is connected to the separator inlet 51 through the third channel 62. The separator outlet 52 is connected to the suction port 12 through the fourth channel 63.

[0056] Considering that compressor 1 is relatively large and expansion valve 3 is relatively small, compressor 1 and expansion valve 3 are installed on the first surface of flow channel plate 6, while water cooler 2, refrigeration unit 4 and gas-liquid separator 5, which are similar in size, are installed on the second surface of flow channel plate 6 to balance the structural center of gravity.

[0057] Specifically, in this embodiment, the water cooler 2 and the refrigerator 4 are arranged parallel to each other on the second surface of the flow channel plate 6. The water cooler 2 and the refrigerator 4 are positioned near the same edge of the flow channel plate. The gas-liquid separator 5 is located at the edge of the flow channel plate 6 opposite to the water cooler 2 and the refrigerator 4, and is arranged perpendicular to the direction in which the water cooler 2 and the refrigerator 4 are arranged parallel to each other. Figure 3 As shown, the water cooler 2 and the refrigerator 4 are roughly the same size and volume. The refrigerator 4 is located on the top side, and the water cooler 2 is located on the bottom side, both near the right edge of the flow channel plate 6. This allows the water cooler 2's piping to pass through the obstruction of the flow channel plate 6 and directly connect to the exhaust port 11 of the compressor 1 in some cases. The gas-liquid separator 5 is located on the left side to balance the center, resulting in higher integration and a smaller overall size.

[0058] With the above structure, taking refrigeration operation as an example, during operation, the compressor 1's suction port 12 draws in low-temperature, low-pressure refrigerant from the gas-liquid separator 5 through the fourth channel 63. Then, after being compressed by the piston movement, the high-temperature, high-pressure refrigerant is discharged from the suction port 12 towards the water cooler inlet 21 of the water cooler 2. During the process of the high-temperature, high-pressure refrigerant flowing through the water cooler 2, it exchanges heat with the low-temperature liquid in the water cooler 2, is cooled by the low-temperature liquid in the water cooler 2, and is discharged from the water cooler outlet 22 to the first channel 61 of the flow channel plate 6. After flowing through the first channel 61 to the expansion valve 3, it is converted into low-temperature refrigerant. The refrigerant, under low temperature and pressure, enters the second channel of the flow channel plate 6 and then enters the refrigerant inlet 41 of the refrigerant 4. During the process of the low temperature and low pressure refrigerant flowing through the refrigerant 4, it exchanges heat with the high temperature liquid in the refrigerant 4, cooling the high temperature liquid in the refrigerant 4, and then discharges from the refrigerant outlet 42 to the third channel 62 of the flow channel plate 6. After passing through the third channel 62, it flows into the gas-liquid separator 5 through the separator inlet 51, causing the refrigerant to undergo gas-liquid separation. Part of the refrigerant is discharged into the fourth channel 63 through the separator outlet 52 and is finally sucked back into the suction port 12, realizing one complete cycle.

[0059] In the above structural design and use, the integration of the flow channel plate 6 forms an integrated mode centered on the compressor 1, which is easy to install and maintain. Specifically, in this system, a plate-shaped flow channel plate 6 is installed on one side of the larger compressor 1, so that the flow channel plate 6 serves as an integration of pipelines to connect devices such as the water cooler 2, the refrigerator 4, and the gas-liquid separator 5 in series. The independent channels in the flow channel plate 6 form a function that connects each unit individually, forming a simple flow channel system that is easy to plug and install.

[0060] Considering the large size and weight of the compressor 1, the flow channel plate 6 can be installed on one side of the compressor 1 with the compressor 1 as the center, and the compressor 1 can be placed at a position relatively close to the bottom of the flow channel plate 6. Then, according to the layout requirements, the water cooler 2, the refrigerator 4, the gas-liquid separator 5 and other devices can be installed and connected to the flow channel plate 6 one by one.

[0061] In the above embodiment, the expansion valve 3 is connected to the refrigerant inlet 41 through the second channel. The second channel itself can be shortened as much as possible so that the expansion valve 3 has no flow resistance after throttling the refrigerant. In other words, in this embodiment, the second channel can actually be regarded as a connecting pipe that runs through the flow channel plate 6 along the thickness direction of the vertical flow channel plate 6.

[0062] Instead of passing through the flow channel plate 6, the connection between the exhaust port 11 of the compressor 1 and the water cooler inlet 21 of the water cooler 2 is achieved by direct connection. The purpose of this is to reduce the impact of high pressure flow resistance when the exhaust port 11 is directly connected.

[0063] In the above embodiment, the water cooler 2 and the refrigerator 4 are located on the side near the compressor exhaust port 11, and the gas-liquid separator 5 is located on the side near the compressor suction port 12. That is to say, in addition to facilitating the direct connection between the water cooler 2 pipeline and the compressor 1 exhaust port 11 through the obstruction of the flow channel plate 6 in some cases, it also shortens the path between the gas-liquid separator 5 and the compressor 1 suction port 12, minimizing the pipeline length.

[0064] Example 2

[0065] Please see Figure 6-9 In this embodiment, the center of mass of the water cooler 2 and the center of mass of the refrigerator 4 are respectively located on both sides of the vertical plane of the preset center of mass. Specifically, the flow channel plate 6 has a first surface and a second surface arranged opposite to each other. The compressor 1 and the refrigerator 4 are attached to the first surface of the flow channel plate 6, and the water cooler 2, the expansion valve 3, and the gas-liquid separator 5 are attached to the second surface of the flow channel plate 6. Independent first channels 61, second channels, third channels 62, and fourth channels 63 are formed in the flow channel plate 6. The exhaust port 11 is connected to the water cooler inlet 21. The water cooler outlet 22 is connected to the expansion valve 3 through the first channel 61. The expansion valve 3 is connected to the refrigerator inlet 41 through the second channel. The refrigerator outlet 42 is connected to the separator inlet 51 through the third channel 62. The separator outlet 52 is connected to the suction port 12 through the fourth channel 63. The refrigerator 4 is located at the top of the compressor 1.

[0066] With the above structure, taking refrigeration operation as an example, during operation, the compressor 1's suction port 12 draws in low-temperature, low-pressure refrigerant from the gas-liquid separator 5 through the fourth channel 63. Then, after being compressed by the piston movement, the high-temperature, high-pressure refrigerant is discharged from the suction port 12 towards the water cooler inlet 21 of the water cooler 2. During the process of the high-temperature, high-pressure refrigerant flowing through the water cooler 2, it exchanges heat with the low-temperature liquid in the water cooler 2, is cooled by the low-temperature liquid in the water cooler 2, and is discharged from the water cooler outlet 22 to the first channel 61 of the flow channel plate 6. After flowing through the first channel 61 to the expansion valve 3, it is converted into low-temperature refrigerant. The refrigerant, under low temperature and pressure, enters the second channel of the flow channel plate 6 and then enters the refrigerant inlet 41 of the refrigerant 4. During the process of the low temperature and low pressure refrigerant flowing through the refrigerant 4, it exchanges heat with the high temperature liquid in the refrigerant 4, cooling the high temperature liquid in the refrigerant 4, and then discharges from the refrigerant outlet 42 to the third channel 62 of the flow channel plate 6. After passing through the third channel 62, it flows into the gas-liquid separator 5 through the separator inlet 51, causing the refrigerant to undergo gas-liquid separation. Part of the refrigerant is discharged into the fourth channel 63 through the separator outlet 52 and is finally sucked back into the suction port 12, realizing one complete cycle.

[0067] In this embodiment, the volume of the flow channel plate 6 can be reduced by placing the cooler 4 on top of the compressor 1, thereby balancing and reducing weight. Specifically, in this invention, the cooler 4, which should originally be separate from the compressor 1, is placed on the same side of the compressor 1 and on top of it, sharing the same top position area with the compressor 1. The original water cooler 2 and gas-liquid separator 5 are still kept on the second side of the flow channel plate, making the center of gravity of the first and second sides of the flow channel plate 6 more balanced. At the same time, since the volume of the devices on the second side of the flow channel plate 6 is reduced, the flow channel plate 6 can be made shorter in the horizontal direction, reducing its weight and thus controlling costs.

[0068] In this embodiment, the compressor 1 is placed horizontally at the bottom along its long side, and its long side is attached to and installed with the flow channel plate 6. The cooler 4 is also placed horizontally along the placement direction of the compressor 1, and its long side is attached to and installed with the flow channel plate 6. Therefore, the first side of the flow channel plate 6 can have the highest space utilization rate.

[0069] Specifically, in this embodiment, the cooler 4 is installed near the top edge of the flow channel plate 6, and the cooler inlet 41 and the cooler outlet 42 are arranged horizontally relative to each other.

[0070] Since the cooler 4 is installed on top of the compressor 1, the space on the second side of the flow channel plate 6 facing the cooler 4 can be dedicated to docking the cooler 4 without being obstructed by the larger compressor 1.

[0071] In the above embodiment, the expansion valve 3 is connected to the refrigerant inlet 41 through the second channel. The second channel itself can be shortened as much as possible so that the expansion valve 3 has no flow resistance after throttling the refrigerant. In other words, in this embodiment, the second channel can actually be regarded as a connecting pipe that runs through the flow channel plate 6 along the thickness direction of the vertical flow channel plate 6.

[0072] Instead of passing through the flow channel plate 6, the connection between the exhaust port 11 of the compressor 1 and the water cooler inlet 21 of the water cooler 2 is achieved by direct connection. The purpose of this is to reduce the impact of high pressure flow resistance when the exhaust port 11 is directly connected.

[0073] Furthermore, the water cooler 2 is vertically positioned near the edge of the flow channel plate 6, with the water cooler inlet 21 and outlet 22 perpendicular to each other. Therefore, in this embodiment, the water cooler outlet 22 can be positioned on the upper side, which facilitates shortening the distance to the downstream expansion valve 3 and gas-liquid separator 5, and avoids obstruction by the compressor 1.

[0074] Similarly, the gas-liquid separator 5 is vertically arranged on the side adjacent to the water cooler 2, with the separator inlet 51 and separator outlet 52 arranged perpendicularly to each other. Therefore, in this embodiment, this layout can shorten the distance between the cooler outlet 42 and the separator inlet 51, and also shorten the distance between the separator outlet 52 and the suction port 12 on the bottom side of the compressor 1, forming a compact layout.

[0075] The first channel 61, the third channel 62, and the second channel 63 are arranged in a horizontal direction. In other words, considering the arrangement of the water cooler 2 and the refrigeration unit 4, the first channel 61, the third channel 62, and the second channel 63 on the flow channel plate 6 can all be made in a parallel horizontal manner. This makes it easier to process, simplifies the pipeline layout, reduces manufacturing costs, and allows the flow channel plate 6 itself to be made thinner and lighter.

[0076] Example 3

[0077] Please see Figure 10-14 In this embodiment, the flow channel plate 6 has a first surface and a second surface arranged opposite to each other. The compressor 1 and the cooler 4 are attached to the first surface of the flow channel plate 6, and the expansion valve 4 and the gas-liquid separator 5 are attached to the second surface of the flow channel plate 6. Independent first channels 61, second channels, third channels 62 and fourth channels 63 are formed inside the flow channel plate 6. The exhaust port 11 is connected to the water cooler inlet 21. An extension pipe 7 is provided between the water cooler 2 and the first surface of the flow channel plate 6. The water cooler outlet 22 is connected to the first channel 61 through the extension pipe 7 and to the expansion valve 3 through the first channel 61. The expansion valve 3 is connected to the cooler inlet 41 through the second channel. The cooler outlet 42 is connected to the separator inlet 51 through the third channel 62. The separator outlet 52 is connected to the suction port 12 through the fourth channel 63. The water cooler 2 and the cooler 4 are located at the top of the compressor 1, and the water cooler 2 is located on the side of the cooler 4 away from the first surface of the flow channel plate 6.

[0078] With the above structure, taking refrigeration operation as an example, during operation, the compressor 1's suction port 12 draws in low-temperature, low-pressure refrigerant from the gas-liquid separator 5 through the fourth channel 63. Then, after being compressed by piston movement, the high-temperature, high-pressure refrigerant is discharged from the suction port 12 towards the water cooler inlet 21 of the water cooler 2. During the flow of the high-temperature, high-pressure refrigerant through the water cooler 2, it undergoes heat exchange with the low-temperature liquid in the water cooler 2, is cooled by the low-temperature liquid in the water cooler 2, and is discharged from the water cooler outlet 22 into the extension pipe 8. It then enters the first channel 61 of the flow channel plate 6 through the extension pipe 8 towards the flow channel plate 6, and flows through the first channel 61 to... At position 3 of the expansion valve, the refrigerant is converted to a low-temperature, low-pressure state and enters the second channel of the flow channel plate 6. Then, it enters the refrigerant inlet 41 of the refrigerant 4. During the process of the low-temperature, low-pressure refrigerant flowing through the refrigerant 4, it exchanges heat with the high-temperature liquid in the refrigerant 4, cooling the high-temperature liquid in the refrigerant 4. The liquid is then discharged from the refrigerant outlet 42 to the third channel 62 of the flow channel plate 6. After passing through the third channel 62, it flows into the gas-liquid separator 5 through the separator inlet 51, causing the refrigerant to undergo gas-liquid separation. Part of the refrigerant is discharged into the fourth channel 63 through the separator outlet 52 and is finally drawn back to the suction port 12, completing one complete cycle.

[0079] In this embodiment, by placing the refrigerator 4 and water cooler 6 on top of the compressor 1 and lowering the compressor 1, the center of gravity becomes more balanced, and the overall space occupied is smaller. Specifically, in this utility model, the refrigerator 4 is set close to the flow channel plate 6 and is located above the compressor 1. Heat exchange is achieved through the flow channel plate 6. Similarly, the water cooler 2 is set above the compressor 1 and can be connected to the flow channel plate 6 through an extension pipe 8. Therefore, heat exchange is also achieved through the flow channel plate 6. Through the above structural arrangement, the relatively heavy and bulky refrigerator 2 and water cooler 4 are placed on top of the compressor 1, so that the refrigerator 2, water cooler 4, and the heavier and more stable compressor 1 form a compact and reliable installation relationship.

[0080] Of these, compressor 1 has the largest volume, and its cylinder body is made of metal, making it quite heavy. Therefore, compressor 1 is better suited to support the water cooler 2 and the refrigeration unit 4 on top, considering stability. It is worth noting that compared to some other comparative examples, such as placing both water cooler 2 and refrigeration unit 4 together, or one of them, on the side away from compressor 1 and directly supporting them with the flow channel plate 6 or other reinforcing components, the stability is significantly less than that achieved in this embodiment by directly supporting them with compressor 1.

[0081] Furthermore, since the compressor 1 itself is relatively large, and the water cooler 2 and the refrigeration unit 4 are also relatively large, by fitting these three large-volume structures together to form a complete main structure, a higher space utilization rate can be achieved. This avoids the situation where a single component is suspended on one side, making it difficult to utilize the space between two relatively large components.

[0082] In the above embodiment, the expansion valve 3 is connected to the refrigerant inlet 41 through the second channel. The second channel itself can be shortened as much as possible so that the expansion valve 3 has no flow resistance after throttling the refrigerant. In other words, in this embodiment, the second channel can actually be regarded as a connecting pipe that runs through the flow channel plate 6 along the thickness direction of the vertical flow channel plate 6.

[0083] Similarly, the refrigerant outlet 42 is positioned opposite to the separator inlet 51, and the third channel 62 is positioned to penetrate the flow channel plate 6 along its thickness direction. In other words, in this embodiment, the third channel 62 can also be regarded as a connecting pipe that penetrates the flow channel plate 6 along the direction perpendicular to its thickness, which can also reduce the flow resistance of the refrigerant after it enters the separator inlet 51.

[0084] Structurally, in this embodiment, the cooler 4 is horizontally positioned at the top edge adjacent to the flow channel plate 6, with the cooler inlet 41 and cooler outlet 42 horizontally positioned relative to each other. The water cooler 2 is horizontally positioned on the side adjacent to the cooler 2 facing away from the first surface of the flow channel plate. Therefore, in this embodiment, two parallel main bodies are actually formed on top of the relatively large compressor 1, covering the compressor 1 at its bottom along the projection plane, thus maximizing the utilization of space in the horizontal direction.

[0085] Furthermore, the gas-liquid separator 5 is vertically arranged on the side adjacent to the refrigerator 4, with the separator inlet 51 and separator outlet 52 arranged perpendicularly to each other. Therefore, in this embodiment, this layout can shorten the distance between the refrigerator outlet 42 and the separator inlet 51, and also shorten the distance between the separator outlet 52 and the suction port 12 on the bottom side of the compressor 1, forming a compact layout.

[0086] The extension tube 8 is a tubular component that extends along the direction perpendicular to the thickness of the flow channel plate 6. The extension tube 8 is set close to the top of the compressor 1, and the refrigerator 4 makes a certain horizontal clearance to leave a certain space for the extension tube 8.

[0087] like Figure 12 As shown, mounting holes 64 are provided on the flow channel plate 6. The flow channel plate 6 is vertically mounted on the side wall of the compressor 1 by fasteners passing through the mounting holes 64. Therefore, a good suspension and fixing effect can be achieved for the flow channel plate 6, and it is easy to install.

[0088] In embodiments 2 and 3 above, the water cooler 2 and the refrigerator 4 are mounted on the compressor 1, and the compressor 1 provides load-bearing capacity to the water cooler 2 and the refrigerator 4, thus achieving optimal center of mass balance.

[0089] Note that in the above embodiments, the above-mentioned "mutually perpendicular" or "mutually horizontal" settings on the interface refer to an approximate vertical or horizontal relationship in position, not an absolute vertical or horizontal relationship.

[0090] Based on the above embodiment, compressor 1 has a first end and a second end arranged opposite each other in a horizontal direction. Water cooler 2 and refrigeration unit 4 are disposed on the side adjacent to the first end of compressor 1, and one side of the second end of compressor 1 is connected to controller 7. Specifically, as shown... Figure 1 As shown, the water cooler 2 and the refrigerator 4 are located near the edge of the second side of the flow channel plate 6. The end face of the first end of the water cooler 2 and the refrigerator 4 is almost flush with the end face of the compressor 1, so as to provide the maximum installation space when the controller 7 is installed across the flow channel plate 6 in the horizontal direction, and to achieve the balance of the center of gravity of the first end and the second end in the horizontal direction.

[0091] Meanwhile, in this embodiment, the second end face of the water cooler 2 and the refrigeration unit 4 are arranged adjacent to the first end face of the controller 7. Specifically, in this embodiment, the controller 7 is configured to be connected to one side of the second end of the compressor 1 and has a protruding structure in the direction of the top. Therefore, the water cooler 2, the refrigeration unit 4 and the controller 7 which protrudes to the top at least partially occupy the space above the compressor 1, realizing full utilization of the top space of the compressor 1, which is a stable installation method for the compressor 1 to be completely placed at the bottom.

[0092] In one embodiment, such as Figure 14 As shown, the gas-liquid separator 5 is positioned opposite the compressor 1 at a midpoint. The bottom of the gas-liquid separator 5 is connected to the compressor 1 via an oil return pipe 53. Because the gas-liquid separator 5 is positioned closer to the compressor 1 cylinder in this embodiment, the path of the oil return pipe 53 at the bottom of the gas-liquid separator 5 can actually be shorter, requiring only one external pipe bend to fill the cylinder, thus improving oil return efficiency.

[0093] In one embodiment, the flow channel plate 6 can be configured as a one-piece machined aluminum alloy, which has higher structural strength, better sealing performance, and slightly higher cost. In another embodiment, the flow channel plate 6 is configured as a left-right split assembly, meaning it can be arranged along... Figure 5 The cross-sectional direction shown divides it into two parts, and during installation, the left and right parts are spliced ​​together to form a whole. This method is low-cost and easy to manufacture.
