Description

Technical Field

[0001] This utility model relates to a thermal management system, and more particularly to a compact agent-side integrated module. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[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 designs, structures such as the refrigerator, water cooler, and gas-liquid separator are usually placed on the same side away from the compressor. This causes the compressor's center of gravity to shift, and the specifications of the flow channel plates or pipelines used for connection become larger. This indirectly makes it difficult to control the volume or weight of the flow channel plates or pipelines, thus increasing the overall cost.

[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.

[0008] The compact dosing-side integrated module further includes:

[0009] The flow channel plate has a first surface and a second surface that are arranged opposite to each other. The compressor and the cooler are attached to the first surface of the flow channel plate, and the expansion valve, the water cooler, and the gas-liquid separator are attached to the second surface of the flow channel plate.

[0011] As a further description of the above technical solution, the expansion valve is disposed opposite to the inlet of the cooler, and the second channel is disposed through the flow channel plate along the thickness direction of the flow channel plate.

[0012] As a further description of the above technical solution, the cooler is horizontally arranged near the top edge of the flow channel plate, and the cooler inlet and the cooler outlet are horizontally arranged relative to each other.

[0013] As a further description of the above technical solution, the water cooler is vertically arranged at one edge near the flow channel plate, and the water cooler inlet and the water cooler outlet are arranged perpendicular to each other.

[0014] As a further description of the above technical solution, the gas-liquid separator is vertically arranged on one side adjacent to the water cooler, and the separator inlet and the separator outlet are arranged perpendicular to each other.

[0038] Please see Figure 1-4 This embodiment provides a compact dosage-side integrated module, which includes:

[0039] Compressor 1, the compressor has an exhaust port 11 and an intake port 12;

[0040] Water cooler 2, which includes a water cooler inlet 21 and a water cooler outlet 22;

[0041] Expansion valve 3;

[0042] Refrigerator 4, which includes a refrigerator inlet 41 and a refrigerator outlet 42;

[0043] Gas-liquid separator 5, which includes separator inlet 51 and separator outlet 52;

[0044] The compact dosing-side integrated module also includes:

[0045] The flow channel plate 6 has a first side and a second side arranged opposite to each other. The compressor 1 and the cooler 4 are attached to the first side 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 side of the flow channel plate 6. The separator outlet 52 is connected to the suction port 12 through the fourth channel 63. The cooler 4 is located at the top of the compressor 1.

[0046] Specifically, in this embodiment, the flow channel plate 6 forms independent first channel 61, second channel, third channel 62, and fourth channel 63, wherein 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 cooler inlet 41 through the second channel; and the cooler outlet 42 is connected to the separator inlet 51 through the third channel 62.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] Please see Figure 2 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Furthermore, the gas-liquid separator 5 is positioned relatively close to the middle of the compressor 1. 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 cylinder of the compressor 1 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 the oil return efficiency.

[0057] Please see Figure 4 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.

[0058] In one embodiment, compressor 1 has a first end and a second end arranged opposite each other in a horizontal direction. A water cooler 2 and a refrigerator 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 a controller 7. Specifically, as shown... Figure 1 As shown, the water cooler 2 is located near the edge of the second side of the flow channel plate 6. The end faces of the first end of the water cooler 2 and the refrigerator 4 are almost flush with the end face of the compressor 1 to provide the controller 7 with the maximum installation space and to achieve the balance of the center of gravity of the first and second ends in the horizontal direction.

[0059] Note that the above-mentioned "mutually perpendicular" or "mutually horizontal" settings on the interface refer to an approximate vertical or horizontal relationship in terms of position, not an absolute vertical or horizontal relationship.
