[0013] According to some embodiments of this application, the heat insulation portion is constructed as any one of a plastic part, a ceramic part, or a plastic-ceramic composite part.

[0014] This application proposes a compressor, including: a housing, a low-pressure side component, and a high-pressure side component, wherein the low-pressure side component is disposed in a low-pressure chamber, and the high-pressure side component is disposed in a high-pressure chamber.

[0020] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0026] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.

[0029] The compressor housing is divided into a high-pressure chamber and a low-pressure chamber. As the low-pressure, low-temperature medium flows from the low-pressure chamber to the high-pressure chamber, it is compressed into a high-temperature, high-pressure medium. Therefore, there is a large temperature difference between the low-pressure chamber and the high-pressure chamber, and heat is transferred between them.

[0030] For the high-pressure chamber, heat transfer to the low-pressure chamber side will result in heat dissipation, affecting the cooling effect and cycle efficiency, and increasing energy consumption. For the low-pressure chamber, it will cause the temperature of the low-pressure and low-temperature medium to rise, which will reduce the intake volume efficiency and also reduce the compressor efficiency.

[0031] In summary, heat transfer between the low-pressure chamber and the high-pressure chamber reduces the compressor's performance.

[0032] Based on this, this application proposes a housing in which a heat insulation section is provided between the high-pressure section and the low-pressure section. The heat insulation section can reduce the heat transfer between the low-pressure section and the high-pressure section, thereby reducing the heat transfer between the low-pressure chamber and the high-pressure chamber and improving the working performance of the compressor.

[0033] The compressor in this application embodiment can be applied to vehicles, which can be fuel vehicles, natural gas vehicles, or new energy vehicles. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended vehicles, etc.

[0034] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 300 provided in some embodiments of this application. The vehicle 300 is equipped with a compressor 200, which is used in the vehicle 300's thermal management system. The thermal management system can regulate the temperature of the passenger compartment, the engine system, the electric drive system, the battery device, and the onboard refrigerator, etc.

[0035] The compressor 200 and vehicle 300 according to embodiments of this application are described below with reference to Figures 1-4.

[0036] As shown in Figures 1 and 2, this application proposes a housing 100, which is applied to a compressor 200, that is, the housing 100 is the housing 100 of the compressor 200.

[0037] The housing 100 includes a high-pressure section 10, a low-pressure section 20, and a heat-insulating section 30. The high-pressure section 10 defines a high-pressure chamber, the low-pressure section 20 defines a low-pressure chamber, and the heat-insulating section 30 is located between the high-pressure section 10 and the low-pressure section 20. At least a portion of the heat-insulating section 30 participates in defining the high-pressure chamber and at least a portion participates in defining the low-pressure chamber to reduce heat transfer between the high-pressure section 10 and the low-pressure section 20.

[0038] For example, the housing 100 can be constructed as a one-piece housing, or the housing 100 can be divided into a high-pressure section 10, a heat-insulating section 30 and a low-pressure section 20 arranged sequentially, and the heat-insulating section 30 can be used to reduce heat transfer between the low-pressure section 20 and the high-pressure section 10; the housing 100 can also be constructed as a split housing, with a first housing and a second housing detachably connected, the first housing defining the low-pressure section 20, the second housing defining the high-pressure section 10, and a third housing can be provided between the first housing and the second housing, the third housing defining the heat-insulating section 30, so as to reduce heat transfer between the low-pressure section 20 and the high-pressure section 10 through the heat-insulating section 30. Of course, the heat-insulating section 30 can also be integrated into the first housing or integrated into the second housing.

[0039] Specifically, the inner wall of the high-pressure section 10 defines a high-pressure chamber, the inner wall of the low-pressure section 20 defines a low-pressure chamber, and the heat insulation section 30 is located between the high-pressure section 10 and the low-pressure section 20. A portion of the inner wall of the heat insulation section 30 can participate in defining the high-pressure chamber, and another portion of the inner wall can participate in defining the low-pressure chamber, so as to reduce the heat transfer between the low-pressure section 20 and the high-pressure section 10 of the housing 100 through the heat insulation performance of the heat insulation section 30.

[0040] It should be noted that the heat insulation part 30 is provided between the low-pressure part 20 and the high-pressure part 10, which can reduce the heat transfer between the high-pressure part 10 and the low-pressure part 20 of the housing 100, thereby maintaining the pressure and temperature stability of the low-pressure chamber and the high-pressure chamber.

[0041] The high-pressure chamber contains a high-temperature, high-pressure medium, while the low-pressure chamber contains a low-temperature, low-pressure medium. By reducing the heat transfer between the high-pressure section 10 and the low-pressure section 20 of the casing 100 through the heat insulation section 30, the energy loss of the high-temperature, high-pressure medium in the high-pressure chamber can be reduced, heat dissipation can be reduced, thereby improving the energy efficiency of the compressor 200. The high temperature effect on the low-pressure chamber can also be reduced, thereby reducing the thermal expansion of the low-temperature, low-pressure medium and improving the intake volume efficiency. This can also improve the energy efficiency of the compressor 200 and enhance the operational stability of the compressor 200.

[0042] According to the housing 100 of the present application embodiment, by providing a heat insulation portion 30 between the high-pressure portion 10 and the low-pressure portion 20 of the housing 100, the heat exchange generated between the high-pressure chamber and the low-pressure chamber through the housing 100 can be reduced. This can reduce the heat dissipation of the high-temperature and high-pressure medium in the high-pressure chamber, improve the temperature regulation effect and energy efficiency of the compressor 200, and reduce the impact of the high temperature on the low-pressure chamber to improve the intake volume efficiency. It can also improve the energy efficiency of the compressor 200, improve the working performance of the compressor 200, and extend the service life of the compressor 200.

[0043] Referring to Figures 1 and 2, according to some embodiments of this application, the heat insulation portion 30 is detachably disposed on the low-pressure portion 20, or the heat insulation portion 30 and the low-pressure portion 20 are made of the same material, and the heat insulation portion 30 and the low-pressure portion 20 are integrally formed.

[0044] Specifically, as shown in Figure 1, in some embodiments, the heat insulation portion 30 and the low-pressure portion 20 are integrally formed, and the heat insulation portion 30 and the low-pressure portion 20 are made of the same material, so as to reduce the difficulty of integral forming of the low-pressure portion 20 and the heat insulation portion 30. At the same time, the heat insulation portion 30 can also effectively reduce the heat transfer between the low-pressure portion 20 and the high-pressure portion 10, and reduce the heat transfer on the housing 100, so as to improve the thermal barrier effect between the low-pressure chamber and the high-pressure chamber. As shown in Figure 2, in other embodiments, the heat insulation portion 30 and the low-pressure portion 20 are separately arranged, and the heat insulation portion 30 and the low-pressure portion 20 can be made of the same material or different materials, which can also reduce the heat transfer between the low-pressure portion 20 and the high-pressure portion 10, so as to improve the thermal barrier effect between the low-pressure chamber and the high-pressure chamber.

[0045] Therefore, in the embodiment where the heat insulation part 30 and the low-pressure part 20 are integrally formed, the assembly difficulty can be reduced and the production efficiency can be improved while the energy efficiency, stability and reliability of the compressor 200 are improved. In the embodiment where the heat insulation part 30 and the low-pressure part 20 are detachable, the cost of the housing 100 can be reduced while the energy efficiency, stability and reliability of the compressor 200 are improved.

[0046] According to some embodiments of this application, the sum of the axial dimensions of the low-pressure portion 20 and the heat insulation portion 30 is L1, the axial dimension of the heat insulation portion 30 is L2, and the condition 0.2≤L2 / L1≤0.8 is met.

[0047] Specifically, in embodiments where the low-pressure portion 20 and the heat insulation portion 30 are separately configured, the sum of the dimensions of the low-pressure portion 20 and the heat insulation portion 30 is greater than the dimension of the heat insulation portion 30. The axial dimension of the heat insulation portion 30 can be 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, etc. of the total dimension. In embodiments where the low-pressure portion 20 and the heat insulation portion 30 are integrally formed, the low-pressure portion 20 and the heat insulation portion 30 are made of the same material, and the axial length of the low-pressure portion 20 and the heat insulation portion 30 can be the same.

[0048] This allows for a more reasonable axial dimension of the insulation section 30. On the one hand, it improves the insulation effect of the insulation section 30 in blocking heat transfer between the low-pressure section 20 and the high-pressure section 10. On the other hand, it reduces heat transfer between the shell 100 and the low-temperature, low-pressure medium in the low-pressure chamber, and between the shell 100 and the high-temperature, high-pressure medium in the high-pressure chamber. It also reduces heat dissipation of the high-temperature, high-pressure medium in the high-pressure chamber and thermal expansion of the low-temperature, low-pressure medium in the low-pressure chamber, thereby improving the energy efficiency of the compressor 200 and enhancing its operational stability and reliability.

[0049] According to some embodiments of this application, the heat insulation portion 30 is constructed as any one of a plastic part, a ceramic part, or a plastic-ceramic composite part.

[0050] In some embodiments, the heat insulation portion 30 can be constructed as a plastic part, such as polystyrene (EPS), polyurethane (PU), etc., which can reduce the weight of the housing 100 and improve the thermal efficiency of the compressor 200 while achieving heat insulation between the high-pressure portion 10 and the low-pressure portion 20.

[0051] In some embodiments, the heat insulation portion 30 can be constructed as a ceramic component, such as microporous ceramic. In this way, on the one hand, the ceramic material itself has a high melting point, high hardness and good chemical stability, which enables it to maintain stable performance in high-temperature environments to extend the service life of the shell 100. On the other hand, the heat insulation ceramic material usually has a large number of micropores, which can effectively block the transfer of heat, thereby achieving the effect of heat insulation.

[0052] In addition, some heat-insulating ceramic materials can also improve their heat insulation performance by using special designs and formulations, such as coating the surface with a glaze layer containing aluminum or other highly reflective materials, to reduce the heat radiation absorption capacity of the heat-insulating part 30.

[0053] In some embodiments, the thermal insulation portion 30 is made of a ceramic-plastic composite, which is a composite material that integrates the properties of ceramics and plastics, and has excellent thermal insulation performance and plasticity.

[0054] Therefore, by utilizing the high melting point, high hardness, and good chemical stability of ceramics, and the lightweight, easy-to-process, and corrosion-resistant properties of plastics, the two can be organically combined through special processing techniques. This can give the insulation component 30% better thermal insulation performance and higher mechanical strength.

[0055] Understandably, the high melting point of ceramic materials allows composite insulation components to maintain stable performance at high temperatures, making them less prone to melting or deformation. At the same time, the addition of plastic components gives the composite insulation components a degree of flexibility and plasticity, making them easier to process and install.

[0056] In summary, the heat insulation part 30, which is constructed of plastic, ceramic or plastic-ceramic composite parts, not only improves the heat insulation effect of the housing 100, the thermal efficiency of the compressor 200, the energy efficiency and working stability of the compressor 200, but also reduces the weight of the housing 100 and reduces the difficulty of layout.

[0057] It should be noted that in the embodiment where the heat insulation part 30 and the low-pressure part 20 are integrally formed, a sealing structure is provided between the heat insulation part 30 and the high-pressure part 10. After the low-pressure side component 210 and the high-pressure side component 220 are assembled, the heat insulation part 30 and the high-pressure part 10 can be connected by fasteners. In the embodiment where the heat insulation part 30 and the low-pressure part 20 are detachably connected, a sealing structure is provided between the low-pressure part 20 and the heat insulation part 30, and between the heat insulation part 30 and the high-pressure part 10. After the low-pressure side component 210 and the high-pressure side component 220 are assembled, the low-pressure part 20, the heat insulation part 30, and the high-pressure part 10 can be further assembled by fasteners.

[0058] It is understandable that the high-pressure part 10 of the housing 100 needs to withstand greater pressure, while the low-pressure part 20 withstands less pressure. This application sets up the heat insulation part 30 separately, or the heat insulation part 30 is integrally formed with the low-pressure part 20. For the high-pressure part 10 that needs to withstand greater pressure, the existing structure is maintained, which can also take into account the structural strength and reliability of the housing 100, thereby improving the working stability and reliability of the compressor 200.

[0059] As shown in Figure 3, this application proposes a compressor 200, including: a housing 100, a low-pressure side component 210 and a high-pressure side component 220, wherein the low-pressure side component 210 is disposed in the low-pressure chamber and the high-pressure side component 220 is disposed in the high-pressure chamber.

[0060] Specifically, the housing 100 defines an accommodating space, which can be divided into a low-pressure chamber and a high-pressure chamber. The compressor 200 has a low-pressure side component 210 and a high-pressure side component 220. The low-pressure side component 210 is disposed in the low-pressure chamber, and the high-pressure side component 220 is disposed in the high-pressure chamber.

[0061] The housing 100 has a low-pressure inlet on the low-pressure section 20 and a high-pressure outlet on the high-pressure section 10. The low-temperature, low-pressure medium enters the low-pressure chamber through the low-pressure inlet, flows through the low-pressure side component 210 and the high-pressure side component, and then flows into the high-pressure chamber. Under the action of the low-pressure side component 210 and the high-pressure side component 220 (such as the moving scroll 230 and the stationary scroll, the drive motor, the high-pressure side bearing, the low-pressure side bearing, etc.), it is compressed and becomes a high-temperature, high-pressure medium, which is discharged from the high-pressure outlet. This makes the temperature of the high-pressure chamber higher than that of the low-pressure chamber. The low-pressure section 20 defines the low-pressure chamber, and the high-pressure section 10 defines the high-pressure chamber. As a result, at least part of the heat from the high-temperature, high-pressure medium in the high-pressure chamber is transferred to the high-pressure section 10. The temperature difference between the high-pressure section 10 and the low-pressure section 20 is large, and there is a heat transfer phenomenon between the low-pressure section 20 and the high-pressure section 10 of the housing 100.

[0062] Based on this, the compressor 200 of this application embodiment adopts the housing 100 in the above embodiment. A heat insulation portion 30 is provided between the low-pressure portion 20 and the high-pressure portion 10 of the housing 100. The heat insulation portion 30 can block the heat transfer on the housing 100, thereby reducing the heat dissipation of the high-pressure chamber caused by the housing 100 and the temperature rise of the low-pressure chamber.

[0063] In this way, on the one hand, the heat dissipation of the high-temperature and high-pressure medium in the high-pressure chamber can be reduced, thereby improving the thermal efficiency of the compressor 200 and thus improving the energy efficiency of the compressor 200. On the other hand, the thermal expansion of the low-temperature and low-pressure medium in the low-pressure chamber can be reduced, thereby improving the intake volume efficiency and further improving the energy efficiency of the compressor 200. It also improves the working stability and reliability of the low-pressure side component 210 in the low-pressure chamber, extends the life of the compressor 200, and enhances the overall performance of the compressor 200.

[0064] As shown in Figures 2 and 3, according to some embodiments of this application, the compressor 200 further includes a moving scroll 230, which is located between the low-pressure chamber and the high-pressure chamber, and at least a portion of the moving scroll 230 is located within the radial orthogonal projection profile of the heat insulation portion 30 of the compressor 200.

[0065] Specifically, during the operation of the compressor 200, the medium needs to flow through the stationary scroll and the cooperating moving scroll 230 to perform compression work. The moving scroll 230 is located at the junction of the low-pressure chamber and the high-pressure chamber. One axial side of the moving scroll 230 is the high-pressure chamber, and the other axial side of the moving scroll 230 is the low-pressure chamber. By ensuring that at least a portion of the moving scroll 230 is located within the radial projection outline of the heat insulation portion 30 of the compressor 200, the heat insulation portion 30 can be set near the junction of the high-pressure chamber and the low-pressure chamber, making the setting position of the heat insulation portion 30 more reasonable. This can also further reduce the heat transfer generated on the casing 100, thereby improving the energy efficiency and operational stability of the compressor 200.

[0066] Referring to Figure 3, according to some embodiments of this application, the moving scroll 230 is provided with a heat insulation element on the side facing the high-pressure chamber and / or the side facing the low-pressure chamber to reduce heat transfer between the low-pressure chamber and the high-pressure chamber.

[0067] Specifically, the heat insulation component can be constructed as a heat insulation material component with the same outline as the moving scroll 230, and is fitted onto the side surface of the moving scroll 230 facing the low-pressure chamber, or the side surface of the moving scroll 230 facing the high-pressure chamber. The heat insulation component can also be constructed as a heat insulation sleeve and fitted onto the outside of the moving scroll 230 to reduce heat transfer between the low-pressure chamber and the high-pressure chamber inside the housing 100, thereby further improving the thermal efficiency of the compressor 200 and improving the energy efficiency of the compressor 200.

[0068] According to some embodiments of this application, the heat insulation component is constructed as a heat insulation coating and is applied to the surface of the moving scroll 230.

[0069] Specifically, the heat insulation coating is applied to the side surface of the moving scroll 230 facing the low-pressure chamber, or the heat insulation coating is applied to the side surface of the moving scroll 230 facing the high-pressure chamber, or the moving scroll 230 is coated with a heat insulation coating on both the surface facing the high-pressure chamber and the surface facing the low-pressure chamber.

[0070] Therefore, while ensuring the insulation effect of the insulation component to improve the energy efficiency of the compressor 200, the insulation component can be directly coated on the moving scroll 230, which can also reduce the cost of the insulation component and reduce the difficulty of installing the insulation component.

[0071] It should be noted that the heat insulation coating can be a conductive heat insulation coating, which achieves heat insulation through low thermal conductivity and high thermal resistance, or a radiative heat insulation coating, such as adding fillers with strong infrared radiation capabilities to the coating to dissipate the absorbed energy in the form of radiation. The heat insulation coating can also be a composite heat insulation coating that combines conductive and radiative heat insulation.

[0072] It is understandable that the heat insulation coating is preferably applied to the side of the moving scroll 230 facing the low-pressure chamber. This can also reduce the probability of friction between the moving scroll 230 and surrounding components, which could lead to the heat insulation coating peeling off or failing, and improve the heat insulation stability and reliability of the heat insulation component.

[0073] As shown in Figure 4, this application provides a vehicle 300, including: the compressor 200 in the above embodiment.

[0074] Specifically, vehicle 300 has a thermal management system, which can be used to regulate the temperature of the passenger compartment, engine system, electric drive system, battery device, etc. The thermal management system uses the aforementioned compressor 200. While achieving temperature regulation, compressor 200 has higher energy efficiency and higher operational stability, which can effectively improve the driving comfort of vehicle 300, reduce vehicle 300 energy consumption, improve fuel economy, or increase the driving range of new energy vehicle 300.

[0075] As shown in Figures 1, 2, 3 and 4, the housing 100 of the compressor 200 in this embodiment includes a low-pressure portion 20, a high-pressure portion 10, and a heat insulation portion 30 between the low-pressure portion 20 and the high-pressure portion 10. The heat insulation portion 30 can be constructed as a plastic part, a ceramic part or a plastic-ceramic composite part, and the heat insulation portion 30 can be integrally formed with the low-pressure portion 20.

[0076] Other configurations and operations of the compressor 200 and vehicle 300 according to embodiments of this application are known to those skilled in the art and will not be described in detail here.
