Description

Technical Field

[0001] The present invention relates to a thermal management system, in particular to a mass center balanced thermal management system. Background Art

[0002] The description in this section merely provides background information related to the present disclosure and may not constitute prior art.

[0003] With the development of new energy vehicles, the market is placing higher demands on energy-saving performance and stability in thermal management systems (including air conditioners and refrigerators). A new energy vehicle thermal management system with integrated heat pump technology utilizes a water-cooled LCC (liquid cooler) as the condenser and a water-cooled chiller (refrigerator) as the evaporator. By intelligently controlling the refrigerant and coolant circulation paths, this system achieves efficient cooling, heating, and energy recovery, making it particularly suitable for electric and hybrid vehicles.

[0004] In existing thermal management systems, since the refrigerator and water cooler themselves have a large mass and volume, when they are directly connected to the compressor, they may have a certain impact on the operation of the original compressor, especially the center of mass of the compressor. The center of mass of the compressor is the average position of the mass distribution of the compressor as a whole or the internal rotating parts. The additional load-bearing base and the force applied to the compressor may cause a large offset of the center of mass of the compressor, resulting in unstable operation, noise or looseness.

[0005] It should be noted that the above technical background is merely provided to provide a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. Simply because these solutions are described in the technical background section of the present invention, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0012] As a further description of the above technical solution, the functional element includes a water cooler and a refrigerator, and the water cooler and the refrigerator are installed on the top surface of the compressor.

[0013] As a further description of the above technical solution, the center of mass of the water cooler and the center of mass of the refrigerator are respectively arranged on both sides of the vertical plane of the preset center of mass.

[0014] As a further description of the above technical solution, the center of mass of the water cooler and the center of mass of the refrigerator are equidistant from the vertical plane of the preset center of mass.

[0015] The present invention also provides a method for balancing the center of mass of a thermal management system, wherein the method for balancing the center of mass of the thermal management system comprises the following steps:

[0016] providing a preset center of mass of the compressor;

[0036] To help those skilled in the art better understand the technical solutions in this specification, the following will provide a clear and complete description of the technical solutions in the embodiments of this specification, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of them. All other embodiments derived by those skilled in the art based on the embodiments in this specification without creative effort shall fall within the scope of protection of this specification.

[0037] The following is an explanation of the embodiments of the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual dimensions. It is stated in advance. The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0038] It should be understood that although terms such as "first," "second," and "third" may be used herein 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. In addition, the term "or" as used herein may include any one or more combinations of the associated listed items, as appropriate.

[0039] See Figure 1-3 , is a mass-balanced thermal management system of this embodiment, wherein the mass-balanced thermal management system includes: a compressor 1 and multiple functional elements, the compressor 1 has a preset mass center, and the mass center of the overall structure of the multiple functional elements is close to or located on the vertical plane of the preset mass center.

[0040] The center-of-mass-balanced thermal management system of the present invention can adjust the installation positions of the water cooler 2 and refrigerator 4, which serve as functional components, based on the preset center of mass of the compressor 1. This allows the water cooler 2 and refrigerator 4 to directly bear the load of the compressor 1, thereby reducing vibration and abnormal noise caused by the center of mass shift during the operation of the compressor 1. Specifically, the present invention uses the compressor 1 as the center of mass to balance the positions of the refrigerator 4 and water cooler 2, which are larger in size and weight, so that they are closer to the center of mass of the compressor 1, minimizing the impact of the center of mass shift on the compressor and making the compressor 1 more stable in operation.

[0041] The functional elements mainly adjusted in this application may be the water cooler 2 and the refrigerator 4 which also have relatively large volumes.

[0042] Specifically, see Figure 4 The comparative example is a schematic diagram of a thermal management system that has not undergone center of mass balance, wherein the water cooler 2 and the refrigerator 4 are arranged on one side of the horizontal direction of the compressor 1, and are suspended and fixed by means of the flow channel plate 6, and the above-mentioned corresponding structures are connected in series in the same thermal management system to facilitate the flow of the refrigerant. Therefore, the compressor 1 is subjected to a force from one side of the flow channel plate 6. When viewed as a whole, due to the large weight of the water cooler 2 and the refrigerator 4 themselves, the center of mass of the compressor 1 is affected by the water cooler 2 and the refrigerator 4, and its original preset center of mass is shifted too much toward the side of the water cooler 2 and the refrigerator 4, resulting in unstable operation of the compressor 1 or even vibration and abnormal noise due to the shift of the preset center of mass during subsequent operation.

[0043] To this end, in this embodiment, the preset center of mass of the compressor 1 can be determined based on the original compressor 1. Specifically, the preset center of mass of the compressor 1 can be provided in advance by the manufacturer and determined under the influence of the counterweight of the compressor 1 itself, and is generally set at the upper middle position of the main shaft of the compressor 1. Then, the positions of the water cooler 2 and the refrigerator 4 as functional elements can be adjusted in a targeted manner, so that the water cooler 2 or the refrigerator 4 or both or one of them moves closer to the center of mass and still maintains a fixed connection with the outer wall of the compressor 1. Therefore, the center of mass offset of the adjusted overall thermal management system is smaller.

[0044] See Figure 1 The following is an embodiment of achieving center of mass balance based on position adjustment of the water cooler 2:

[0045] In this embodiment, a compressor 1, a water cooler 2, an expansion valve 3, a refrigerator 4, a gas-liquid separator 5, and a manifold plate 6 are provided. The manifold plate 6 has a first surface and a second surface arranged opposite each other. The compressor 1 and refrigerator 4 are mounted on the first surface of the manifold plate 6, and the water cooler 2, the expansion valve 3, and the gas-liquid separator 5 are mounted on the second surface of the manifold plate 6. Multiple independent channels are formed within the manifold 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 manifold plate 6; the expansion valve 3 is connected to the inlet of the refrigerator 4 through the manifold plate 6; the outlet of the refrigerator 4 is connected to the inlet of the gas-liquid separator 5 through the manifold plate 6; the outlet of the gas-liquid separator 5 is connected to the intake port of the compressor 1 through the manifold plate 6; and 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 manifold plate 6 can be reduced to achieve balance and reduce weight. Specifically, in the present invention, the refrigerator 4 that should be separated from the compressor 1 is placed on the same side of the compressor 1 and at the top of the compressor 1, so that it shares the same top position area with the compressor 1, while the original water cooler 2 and the gas-liquid separator 5 are still kept on the side of the second surface of the flow channel plate, so that the center of gravity on both sides of the first and second surfaces of the flow channel plate 6 is more balanced. At the same time, since the volume of the device on the side of the second surface of the flow channel plate 6 is reduced, the flow channel plate 6 can be made shorter in the horizontal direction, reducing its own weight to achieve cost control. That is to say, based on this embodiment, compared with Figure 4 In the comparative example, since the position of the water cooler 2 is moved to the top position closer to the preset center of mass of the compressor 1, the effect of the preset center of mass offset after its installation is reduced, and the overall volume is made smaller.

[0046] At the same time, based on the above embodiments, considering that the general preset center of mass is set at the upper middle part of the main shaft of the compressor 1, the water cooler 2 and the refrigerator 4 can be installed on the top surface of the compressor 1 to achieve an adjustment method that is closest to the preset center of mass.

[0047] See Figure 2 The following is an embodiment of achieving mass center balance based on the joint adjustment of the positions of the water cooler 2 and the refrigerator 4:

[0048] In this embodiment, a compressor 1, a water cooler 2, an expansion valve 3, a refrigerator 4, and a liquid reservoir 8 are provided. In this embodiment, a flow channel plate 6 is not provided. Instead, the water cooler 2, expansion valve 3, refrigerator 4, and liquid reservoir 8 are directly plugged and fixed to the compressor 1. The top of the compressor 1 has a contoured surface 13, and the water cooler 2, expansion valve 3, refrigerator 4, and liquid reservoir 8 are mounted on the contoured surface 13 of the compressor 1. The inlet of the compressor 1 is vertically plugged and connected to the inlet of the water cooler 2; the outlet of the water cooler 2 is horizontally plugged and connected to the inlet of the liquid reservoir 8; the outlet of the liquid reservoir 8 is horizontally plugged and connected to the expansion valve 3; the expansion valve 3 is horizontally plugged and connected to the inlet of the refrigerator 4; and the outlet of the refrigerator 4 is vertically plugged and connected to the intake port of the compressor 1. In this embodiment, by using the compressor 1 as the center of gravity to bear the weight, the corresponding components can be directly plugged and fixed on the contoured surface 13 of the compressor 1, which is low-cost and easy to install. Among them, the present invention directly takes the compressor 1, which is larger in size and weight, as the center, and sets a contoured surface 13 on the top surface of the compressor 1 for directly installing and positioning the corresponding components, and directly plugs in the water cooler 2, refrigerator 4, liquid storage tank 8 and other structures above it to form a complete flow channel. Compared with the existing structure that requires the help of additional pipelines, this solution is small in size and easy to install. Compared with the solution of organizing the refrigerant flow path with the help of a flow channel plate, it is lower in cost, lighter in weight, and easier to install. That is to say, in this embodiment, the water cooler 2 and refrigerator 4 are both installed on the top of the compressor 1. Specifically, the water cooler 2 is installed on one side of the first installation space, and the refrigerator is installed on one side of the second installation space, and the two are arranged in an approximately mirror image, so that the two are balanced on the left and right sides of the main shaft of the compressor 1, minimizing the impact on the preset center of mass. In addition, the flow channel plate 6 is omitted in this embodiment, and the flow channel plate 6 itself has a certain mass, so the impact on the offset of the preset center of mass is further reduced.

[0049] See Figure 3 , the scheme is the same as above Figure 2 The embodiment is similar to that of , which is an embodiment based on the joint adjustment of the positions of the water cooler 2 and the refrigerator 4 to achieve center of mass balance, but a flow channel plate 6 is introduced to achieve fixation or connection of corresponding components:

[0050] 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 mounted on the first surface of the flow channel plate 6, and the expansion valve 4 and the gas-liquid separator 5 are mounted on the second surface of the flow channel plate 6; a plurality of independent channels are formed in the flow channel plate 6, wherein 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 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; the outlet of the gas-liquid separator 5 is connected to the intake port of the compressor 1 through the flow channel plate 6; the water cooler 2 and the refrigerator 4 are arranged at the top position of the compressor 1, and the water cooler 2 is arranged on the side of the refrigerator 4 away from the first surface of the flow channel plate 6. In this embodiment, the refrigerator 4 and the water cooler 6 can be arranged on the top of the compressor 1, and the compressor 1 can be placed downward, so that the center of gravity is more balanced and the overall space occupied is smaller. Specifically, in the invention, the refrigerator 4 is arranged in contact with the flow channel plate 6 and is arranged above the compressor 1, and the intervention in the heat exchange is achieved through the flow channel plate 6, while the water cooler 2 is arranged above the compressor 1 as above, and the connection to the flow channel plate 6 can be achieved through an extension pipe. Therefore, the intervention in the heat exchange is also achieved through the flow channel plate 6. Through the above-mentioned structural arrangement, the refrigerator 2 and the water cooler 4 with relatively large weight and volume are arranged on the top of the compressor 1, so that the refrigerator 2, the water cooler 4 and the heavier and more stable compressor 1 form a compact and reliable installation relationship. This example uses the flow channel plate 6 to replace Figure 2 In the plug-in mode, the gas-liquid separator 5 can be set on the side away from the water cooler 2 and the refrigerator 4, and 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 the above-mentioned solution without the flow channel plate 6, the liquid storage tank 8 needs to be set at one end of the compressor 1 away from the preset center of mass. The flow channel plate 6 in this embodiment has a stable structure and can play an auxiliary fixing effect. Among them, the above-mentioned closest position refers to the horizontal position of the gas-liquid separator 5, which is moved with the flow channel plate 6 as the reference plane, so that it is closest to the preset center of mass.

[0051] It is worth noting that see Figure 1-3In the present invention, the controller 7 is set at a position between the first installation space and the second installation space, and the controller 7 is hung and fixed on the side wall of the compressor 1. The weight of the controller 7 in the first installation space and the second installation space is balanced so that the weight of the controller 7 in the first installation space is equal to the weight in the second installation space. Specifically, the controller 7 can be a cover-shaped block structure installed at one end of the compressor 1 in the horizontal direction. By dividing the controller 7 with the help of the first installation space and the second installation space, the controller 7 is divided into two for left and right balancing, which can avoid the change of the balance of the thermal management system caused by the weight of the controller 7 and further reduce the impact on the preset center of mass of the compressor 1.

[0052] The present invention also provides a method for adjusting the mass center, wherein the preset mass center of the compressor 1 is first provided; then the water cooler 2 or the refrigerator 4 is moved closer to the preset mass center and fixedly connected to the outer wall of the compressor 1.

[0053] In the above method, a vertical plane is set according to the preset center of mass of the compressor 1, and the space is divided into a first installation space and a second installation space that are relatively set. The water cooler 2 is set at the position of the first installation space, and the refrigerator 4 is set at the position of the second installation space. The distance between the water cooler 2 and the refrigerator 4 and the vertical plane is made equal, so as to achieve the balance of the center of mass as much as possible and get closer to the vertical plane of the preset center of mass. Specifically, the vertical plane can be regarded as a vertically set plane that passes through the preset center of mass of the compressor 1. Therefore, it has a guiding role in the adjustment of the horizontal components. Any adjustment close to the vertical plane may reduce the offset of the preset center of mass.

[0054] At the same time, by placing the water cooler 2 and the refrigerator 4 separately in the first installation space and the second installation space, the water cooler 2 and the refrigerator 4 can form a center of mass balance in a mirrored setting 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 installation space and the second installation space in this embodiment are respectively on the left and right sides of the compressor 1, forming a mirrored balance of the weight on both sides of the preset center of mass.

[0055] In general, the present invention takes the compressor 1 as the center of gravity, and balances the positions of the refrigerator 2 and the water cooler 4, which are larger in volume and weight, so that they are closer to the center of mass of the compressor 1, minimizing the impact of the center of mass deviation of the compressor 1, and making the compressor more stable in operation.
