Description

Technical Field

[0001] This utility model relates to a thermal management system, and more particularly to a thermal management system with a center of mass balance. 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, the large mass and volume of the chillers and water coolers can affect the operation of the compressor when they are directly connected to it, especially the compressor's center of gravity. The compressor's center of gravity is the average position of the mass distribution of the compressor as a whole or its internal rotating parts. This additional force on the compressor as a load-bearing foundation can cause a large displacement of the compressor's center of gravity, resulting in unstable operation, noise, or loosening.

[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.

[0036] 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.

[0037] Please see Figure 1-3 This embodiment provides a center-of-mass balanced thermal management system, which includes a compressor 1 and multiple functional components. The compressor 1 has a preset center of mass, and the center of mass formed by the multiple functional components is adjacent to or located on the vertical plane of the preset center of mass.

[0038] The thermal management system based on the centroid balance of this invention can adjust the installation positions of the water cooler 2 and the refrigerator 4, which are functional components, based on the preset centroid of the compressor 1. This reduces vibration and abnormal noise caused by centroid shift during compressor 1 operation, even when the compressor 1 is directly bearing the load. Specifically, this invention uses the compressor 1 as its center of gravity to balance the positions of the larger refrigerator 4 and water cooler 2, bringing them closer to the centroid of the compressor 1. This minimizes the impact of centroid shift on the compressor, resulting in more stable operation of the compressor 1.

[0039] The main functional elements adjusted in this application can be water cooler 2 and refrigerator 4, which also have relatively large volumes.

[0040] Specifically, please see Figure 4 The comparative example is a schematic diagram of a thermal management system without centroid balancing. In this system, water cooler 2 and refrigerant 4 are located on one side of compressor 1 in the horizontal direction and are suspended and fixed by flow channel plate 6. The corresponding structures are connected in series in the same thermal management system to facilitate the flow of refrigerant. Therefore, compressor 1 is subjected to a force from one side of flow channel plate 6. Considering it as a whole, due to the large weight of water cooler 2 and refrigerant 4, the centroid of compressor 1 is shifted too much from its original preset centroid to the side of water cooler 2 and refrigerant 4 under the influence of water cooler 2 and refrigerant 4. This may cause compressor 1 to experience unstable operation or even vibration and abnormal noise during subsequent operation due to the shift of the preset centroid.

[0041] In this embodiment, the preset center of mass of the compressor 1 can be determined first based on the existing compressor 1. Specifically, the preset center of mass of the compressor 1 can be provided by the manufacturer and determined by the influence of the counterweight of the compressor 1 itself, and is generally set in the upper middle part of the main shaft of the compressor 1. Then, the positions of the water cooler 2 and the refrigerator 4, which are functional components, can be adjusted in a targeted manner, so that either the water cooler 2 or the refrigerator 4, or one of them, moves closer to the center of mass while still maintaining a fixed connection with the outer wall of the compressor 1. Therefore, the center of mass offset of the overall thermal management system after adjustment is smaller.

[0042] Please see Figure 1 The following is an example of achieving centroid balance based on the position adjustment of water cooler 2:

[0043] In this embodiment, a compressor 1, a water cooler 2, an expansion valve 3, a refrigerator 4, a gas-liquid separator 5, and a flow channel plate 6 are provided. 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 fitted onto 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 fitted onto the second surface of the flow channel plate 6. Multiple independent channels are formed within the flow channel plate 6. 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. The refrigerator 4 is located at the top of the compressor 1. In this embodiment, by placing the refrigerator 4 at the top of the compressor 1, the volume of the flow channel plate 6 is reduced, thereby balancing and reducing the weight. Specifically, in this invention, the original cooler 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 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, because the volume of the device 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. In other words, based on this embodiment, compared to… Figure 4 Compared to the comparison, by moving the position of the water cooler 2 to the top position closer to the preset center of mass of the compressor 1, the effect of the preset center of mass shift after its installation is achieved, and the overall volume is made smaller.

[0044] Meanwhile, based on the above embodiments, considering that the preset center of mass is usually set in the upper part of the compressor 1 main shaft, the water cooler 2 and the refrigerator 4 can be installed on the top surface of the compressor 1 to achieve the adjustment method closest to the preset center of mass.

[0045] Please see Figure 2 The following is an example of achieving centroid balance based on the joint adjustment of the positions of water cooler 2 and refrigerator 4:

[0046] In this embodiment, a compressor 1, a water cooler 2, an expansion valve 3, a refrigerator 4, and a liquid storage tank 8 are provided. This embodiment does not include a flow channel plate 6; instead, the water cooler 2, expansion valve 3, refrigerator 4, and liquid storage tank 8 are directly plugged into and fixed to the compressor 1. The compressor 1 has a contoured surface 13 on its top, on which the water cooler 2, expansion valve 3, refrigerator 4, and liquid storage tank 8 are mounted. The inlet of the compressor 1 is vertically connected to the inlet of the water cooler 2; the outlet of the water cooler 2 is horizontally connected to the inlet of the liquid storage tank 8; the outlet of the liquid storage tank 8 is horizontally connected to the expansion valve 3; the expansion valve 3 is horizontally connected to the inlet of the refrigerator 4; and the outlet of the refrigerator 4 is vertically connected to the suction port of the compressor 1. In this embodiment, by using the compressor 1 as the center of gravity for load-bearing, the corresponding components can be directly plugged into the contoured surface 13 of the compressor 1, resulting in lower cost and easier installation. In this invention, the compressor 1, being relatively large and heavy, is used as the center. A contoured surface 13 is provided on the top surface of the compressor 1 for direct mounting and positioning of corresponding components. The water cooler 2, the refrigeration unit 4, the liquid storage tank 8, and other structures above the compressor 1 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 solutions that use flow channel plates to organize the refrigerant flow path, it is lower in cost, lighter in weight, and easier to install. In other words, in this embodiment, both the water cooler 2 and the refrigeration unit 4 are mounted on top of the compressor 1. Specifically, the water cooler 2 is mounted on one side of the first mounting space, and the refrigeration unit is mounted on the other side of the second mounting space, with the two arranged approximately in mirror image, so that they are balanced on the left and right sides of the compressor 1's main shaft, minimizing the impact on the preset center of mass. Furthermore, this embodiment eliminates the flow channel plate 6, which itself has a certain mass, thus further reducing the impact on the preset center of mass offset.

[0047] Please see Figure 3 The plan is the same as the above. Figure 2 Similar to the embodiment, this is an embodiment that achieves centroid balance based on the joint adjustment of the positions of the water cooler 2 and the refrigerator 4, but it incorporates a flow channel plate 6 to fix or connect the corresponding components:

[0048] In this embodiment, a compressor 1, a water cooler 2, an expansion valve 3, a refrigerator 4, a gas-liquid separator 5, and a flow channel plate 6 are provided. 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 expansion valve 4 and the gas-liquid separator 5 are attached to the second surface of the flow channel plate 6. Multiple independent channels are formed inside the flow channel plate 6. The exhaust port of the compressor 1 is directly connected to the inlet of the water cooler 2. An extension pipe is provided between the water cooler 2 and the first surface of the flow channel plate 6. The outlet of the water cooler 2 is connected to the flow channel plate 6 through the extension pipe and 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. The outlet of the gas-liquid separator 5 is connected to the suction port of the compressor 1 through the flow channel plate 6. The water cooler 2 and the refrigerator 4 are located at the top of the compressor 1, and the water cooler 2 is located on the side of the refrigerator 4 away from the first surface of the flow channel plate 6. 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 positioned above the compressor 1. The flow channel plate 6 facilitates heat exchange. Similarly, the water cooler 2 is positioned above the compressor 1 and can be connected to the flow channel plate 6 via an extension pipe. Therefore, it also facilitates heat exchange through the flow channel plate 6. Through the above structural arrangement, the relatively heavy and bulky refrigerator 2 and water cooler 4 are positioned on top of the compressor 1, forming a compact and reliable installation relationship between the refrigerator 2, water cooler 4, and the heavier and more stable compressor 1. This example uses the flow channel plate 6 instead of... Figure 2 In the plug-in method, the gas-liquid separator 5 can be positioned on the side away from the water cooler 2 and the refrigerator 4. By moving it horizontally to the position closest to the preset center of mass, the influence of the gas-liquid separator 5 on the preset center of mass is minimized. In contrast, the above-mentioned solution without a flow channel plate 6 requires the liquid storage tank 8 to be positioned at the end of the compressor 1 away from the preset center of mass. In this embodiment, the flow channel plate 6 itself has a stable structure and can play a role in auxiliary fixation. The aforementioned closest position refers to the position where the gas-liquid separator 5 is moved horizontally with the flow channel plate 6 as the reference plane, so that it is closest to the preset center of mass.

[0049] It is worth noting that, please see Figure 1-3In this invention, the controller 7 is positioned between the first mounting space and the second mounting space, and is suspended and fixed to the side wall of the compressor 1. The weight of the controller 7 is balanced between the first and second mounting spaces, ensuring that its weight in the first mounting space is equal to its weight in the second mounting space. Specifically, the controller 7 can be a cover-shaped block structure mounted horizontally at one end of the compressor 1. By dividing the controller 7 into two parts through the first and second mounting spaces for left-right balance, the weight of the controller 7 can be prevented from altering the balance of the thermal management system, further reducing the impact on the preset center of gravity of the compressor 1.

[0050] The following also provides a method for adjusting the center of mass, wherein a preset center of mass of the compressor 1 is first provided; then the water cooler 2 or the refrigerator 4 is moved closer to the preset center of mass and fixedly connected to the outer wall of the compressor 1.

[0051] In the above method, a vertical plane is set according to the preset center of mass of the compressor 1, dividing the space into a first installation space and a second installation space that are positioned opposite each other. The water cooler 2 is positioned in the first installation space, and the refrigerator 4 is positioned in the second installation space, with the distances of the water cooler 2 and the refrigerator 4 from the vertical plane being equal, so as to achieve the balance of the center of mass as much as possible and get closer to the preset center of mass. Specifically, the vertical plane can be regarded as a vertically set surface that passes through the preset center of mass of the compressor 1. Therefore, it has a guiding role in the adjustment of horizontal components, and any adjustment closer to the vertical plane may reduce the offset of the preset center of mass.

[0052] Meanwhile, by placing the water cooler 2 and the refrigerator 4 in the first and second installation spaces respectively, the water cooler 2 and the refrigerator 4 can form a mirror balance of the center of mass with the vertical plane as the center. That is to say, based on the adjustment scheme close to the preset center of mass, the first and second installation spaces in this embodiment are on the left and right sides of the compressor 1 respectively, forming a mirror balance of the weight on both sides of the preset center of mass.

[0053] In summary, this invention uses the compressor 1 as the center of gravity to balance the positions of the other larger and heavier refrigerator 2 and water cooler 4, making them closer to the center of gravity of the compressor 1. This minimizes the impact on the center of gravity offset of the compressor 1, making the compressor more stable in operation.
