Description

Technical Field

[0001] This utility model relates to a thermal management system, and more particularly to a thermal management system based on compressor load-bearing. 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 thermal management systems, compressors generally have a large relative mass and occupy a large space due to factors such as cylinder material. Therefore, when arranging components such as compressors, refrigerants, and water coolers, a distributed arrangement is often adopted because a compressor-centric design is not considered. This results in a low level of integration of the thermal management system and does not make better use of the compressor itself for load-bearing.

[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.

[0040] Please see Figure 1-4 This embodiment describes a thermal management system based on compressor load-bearing capacity, comprising: a compressor 1, a water cooler 2, and a refrigerator 4, wherein...

[0041] Water cooler 2 and refrigeration unit 4 are fixed on compressor 1, and compressor 1 provides load-bearing capacity to water cooler 2 and refrigeration unit 4.

[0042] Specifically, in this utility model, the compressor 1 is provided with a support foot 14 at its bottom, which is used to fix the compressor 1 to the frame so that the compressor 1 is supported on the frame; the water cooler 2 is provided with a water cooler fixing foot 21, which is used to fix the water cooler 2 to the compressor 1 so that the water cooler 2 is installed on the compressor 1; the refrigeration unit 4 is provided with a refrigeration unit fixing foot 41, which is used to fix the refrigeration unit 41 to the compressor 1 so that the refrigeration unit 2 is installed on the compressor 1.

[0043] With the above structure, during installation, the water cooler 2 can be suspended and fixed on the outer wall of the compressor 1 by connecting the water cooler fixing foot 21 to the corresponding hole on the compressor 1 according to the preset empty space. Similarly, the cooler 4 can be suspended and fixed on the outer wall of the compressor 1 by connecting the cooler fixing foot 41 to the corresponding hole on the compressor 1. The compressor 1 itself is directly connected to the frame of the main structure by means of the support foot 14 at its bottom position, so that the smaller parts are supported by the compressor 1, and the compressor 1 itself is fixed by means of the frame, forming a load-bearing and fixing effect centered on the compressor 1.

[0044] By utilizing the structure of this invention, the water cooler 2, the refrigeration unit 4, and other components can be directly supported by the compressor 1, resulting in a more compact and stable thermal management system. In the thermal management system of this invention, the compressor 1, as a core load-bearing component with a large volume and weight, directly supports the water cooler 2, the refrigeration unit 4, and other parts. It is stably fixed to the frame by the support feet 14 at the bottom, thus creating a stable force relationship for the entire system.

[0045] In this utility model, the water cooler 2 and the refrigerator 4 mentioned above participate in the heat exchange of the refrigerant flow connected in series with the compressor 1 in the thermal management system. Specifically, the connection between the water cooler 2, the refrigerator 4 and the compressor 1 can be set to be organized and connected by means of flying pipes, or by means of flow channel plate 6 which gathers all the pipes into a uniform plate material, or by directly organizing and connecting the adjacent plugs between the compressor 1, the water cooler 2 and the refrigerator 4.

[0046] See details Figure 1 The support foot 14 is positioned near the bottom corner of the compressor 1. Multiple support feet 14 can be provided. Each support foot 14 is a fixing pin that protrudes to the bottom and is inserted into the corresponding mounting position on the frame to achieve a stable fixing effect.

[0047] The following embodiments are specific examples of fixed connection methods based on the above-described ideas.

[0048] Example 1

[0049] Please see Figure 1 In this embodiment, the thermal management system further includes a flow channel plate 6. The flow channel plate 6 has mounting holes and is vertically mounted on the side wall of the compressor 1 using fasteners passing through these holes. The flow channel plate 6 connects the compressor 1, the water cooler 2, and the refrigerator 4. Specifically, the flow channel plate 6 forms multiple independent channels. In this embodiment, the exhaust port of the compressor 1 is directly connected to the inlet of the water cooler 2; the outlet of the water cooler 2 is connected to the expansion valve 3 through the flow channel plate 6; the expansion valve 3 is connected to the inlet of the refrigerator 4 through the flow channel plate 6; the outlet of the refrigerator 4 is connected to the inlet of the gas-liquid separator 5 through the flow channel plate 6; and the outlet of the gas-liquid separator 5 is connected to the suction port of the compressor 1 through the flow channel plate 6. In this embodiment, the water cooler 2 and the refrigerator 4 are suspended and fixed on the side of the flow channel plate 6 facing away from the compressor 1. In the above structural design and use, the integration of the flow channel plate 6 creates an integrated mode centered on the compressor 1, facilitating installation and maintenance. Specifically, in this modular device system, a plate-shaped flow channel plate 6 is installed on one side of the larger compressor 1. The flow channel plate 6 serves as an integrated pipeline for connecting devices such as the water cooler 2, the refrigerator 4, and the gas-liquid separator 5 in series. The independent channels within the flow channel plate 6 create interconnections between each unit, resulting in a simple and easy-to-install flow channel system. 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 positioned 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 are installed and connected to the flow channel plate 6.

[0050] In Example 1, by suspending the refrigerator 2 and the water cooler 4 on the side away from the compressor 1, the compressor 1 and the two are arranged separately, making it easier to install and maintain the compressor 1 side.

[0051] Example 2

[0052] Please see Figure 2This embodiment, like Embodiment 1, features a flow channel plate 6 vertically suspended on one side of the compressor 1 using fasteners and mounting holes. Based on this, the water cooler 2 is suspended and fixed on the side of the flow channel plate 6 facing away from the compressor 1, and the chiller 4 is suspended and fixed on the side of the flow channel plate 6 facing the compressor 1. In this embodiment, by placing the chiller 4 on top of the compressor 1, the volume of the flow channel plate 6 is reduced, thus balancing and reducing weight. Specifically, in this invention, the chiller 4, which should have been separate from the compressor 1, is placed on the same side of the compressor 1 and at the top of the compressor 1, sharing the same top position area with the compressor 1. The original water cooler 2 and gas-liquid separator 5 remain 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. Simultaneously, because 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 controlling costs. 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.

[0053] In Example 2, the cooler 2 and the water cooler 4 are suspended on both sides of the flow channel plate 6 to bear the force, so that the flow channel plate 6 exerts a smaller offset force on the compressor 1 to the side away from the compressor 1, which helps to maintain the stability of the system.

[0054] Example 3

[0055] Please see Figure 3 This embodiment, like Embodiment 1, features a flow channel plate 6 vertically suspended on one side of the compressor 1 using fasteners and mounting holes. Based on this, the cooler 4 is suspended and fixed on the side of the flow channel plate 6 facing away from the compressor 1. A contoured surface 13 is provided on the top of the compressor 1, and the water cooler 2 is mounted on this contoured surface. In this embodiment, by placing the cooler 4 and water cooler 6 on top of the compressor 1 and lowering the compressor 1, the center of gravity is more balanced, and the overall space occupied is smaller. Specifically, in this invention, the cooler 4 is fitted to the flow channel plate 6 and positioned above the compressor 1, allowing heat exchange through the flow channel plate 6. Similarly, the water cooler 2 is positioned above the compressor 1 and connected to the flow channel plate 6 via an extension pipe 8, thus also allowing heat exchange through the flow channel plate 6. This structural arrangement allows the relatively heavy and bulky cooler 2 and water cooler 4 to be positioned on top of the compressor 1, creating a compact and reliable installation relationship between the cooler 2, water cooler 4, and the heavier and more stable compressor 1. (See also...) Figure 3In this embodiment, compressor 1 has the largest volume, and its cylinder body is made of metal, making it quite heavy. Therefore, compressor 1 is used to support the water cooler 2 and the refrigeration unit 4 on top, which is preferable from a stability perspective. 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 by directly supporting them with compressor 1 in this embodiment.

[0056] In embodiment 3, the cooler 2 and the water cooler 4 are both placed on one side of the compressor 1, which makes the center of gravity of the compressor 1 more balanced, and the system integration is more biased towards the compressor 1 side, resulting in a smaller volume.

[0057] Example 4

[0058] Please see Figure 1-3 and Figure 4 In this embodiment, based on the suspended and fixed flow channel plate 6, the thermal management system also includes a gas-liquid separator 5, which is suspended and fixed on the side of the flow channel plate 6 facing away from the compressor 1. The bottom of the gas-liquid separator 5 is connected to the compressor 1 through a return oil pipe 53. Specifically, the gas-liquid separator 5 is used to perform gas-liquid separation when refrigerant is discharged from the refrigerator 4 during the operation of the thermal management system, and to transfer the separated refrigerant back to the cylinder of the compressor 1, thus achieving the separation and buffering effect of the refrigerant. In this embodiment, the relatively small gas-liquid separator 5 is placed on the side facing away from the compressor 1, which has greater layout flexibility and can leave a complete space at the top of the compressor 1 for the arrangement of the device. At the same time, the bottom of the gas-liquid separator 5 is connected to the compressor 1 through a return oil pipe 53. Since the position of the gas-liquid separator 5 is closer to the cylinder of the compressor 1 in this embodiment, the path of the return oil 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.

[0059] Example 5

[0060] Please see Figure 5In this embodiment, the top of the compressor 1 has a contoured surface 13, on which the water cooler 2 and the refrigerant 4 are mounted. Based on this structure, the corresponding components can be directly inserted into the contoured surface 13 of the compressor 1 by using the compressor 1 as the center of gravity for load bearing, resulting in lower cost and easier installation. Specifically, this invention uses the large and heavy compressor 1 as the center, and sets a contoured surface 13 on the top surface of the compressor 1 for direct mounting and positioning of the corresponding components. The water cooler 2, refrigerant 4, liquid storage tank 8, and other structures above it are directly inserted to form a complete flow channel. Compared to existing structures that require additional piping, this solution is smaller and easier to install. Compared to the solutions in the above embodiments that require flow channel plates to organize the refrigerant flow path, it is lower in cost, lighter in weight, and easier to install. In this invention, the contoured surface 13 of the compressor 1 is positioned horizontally at the top of the compressor 1, matching the bottom configuration of the corresponding water cooler 2, refrigerator 4, and other structures. This creates a surface with vertically convex and concave sections, allowing the water cooler 2 and refrigerator 4 to fit snugly onto the top of the compressor 1. For stability, corresponding fasteners are used to secure the bottom extension plates and other structures of the water cooler 2 and refrigerator 4 onto the contoured surface 13 of the compressor 1, achieving a stable and fixed state between the upper and lower structures. Furthermore, in this embodiment, a liquid storage tank 8 installed on the high-pressure side replaces the gas-liquid separator 5 in embodiments 1-4, which can be used with a thermal expansion valve, resulting in a smaller footprint and lower cost.

[0061] In Example 5, the direct plug-in method can eliminate the need for the flow channel plate 6 or connecting pipe, which has a certain mass, thus further reducing the overall system mass.

[0062] Please see Figure 1-4 As a further design of any of embodiments 1-4, the compressor 1 has a first end and a second end arranged opposite to each other. The water cooler 2 and the refrigerator 4 are arranged on one side of the first end of the compressor 1. The thermal management system also includes a controller 7, and the second end of the compressor 1 is connected to the controller 7. The end faces of the first ends of the water cooler 2 and the refrigerator 4 are almost flush with the end face of the compressor 1 to provide maximum installation space for the controller 7 and to achieve horizontal balance between the first end and the second end. At the same time, the end faces of the second ends of the water cooler 2 and the refrigerator 4 are arranged adjacent to the end face of the first end 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 upward direction. Therefore, as Figure 3 As shown, the water cooler 2, the refrigeration unit 4, and the controller 7, which protrudes upwards at least partially, can occupy more space above the compressor 1, thus making full use of the space above the compressor 1 and providing a stable installation method for the compressor 1 to be placed at the bottom.

[0063] Please see Figure 6 The figure shows an exploded view of embodiment 2, in which the mounting holes 61 of the flow channel plate 6 are located near the bottom of the flow channel plate 6. Of course, there can be multiple mounting holes 61, and multiple connecting pins that correspond to the position and size of the mounting holes 61 can be provided on the compressor to achieve stable suspension and fixation.
