[0046] "Multiple" appearing in the present application refers to more than two (including two).

[0047] The shell of the compressor divides into high-pressure chamber and low-pressure chamber, and the low-pressure low-temperature medium is compressed into high-temperature high-pressure medium in the process of flowing from the low-pressure chamber to the high-pressure chamber, so there is a large temperature difference between the low-pressure chamber and the high-pressure chamber, and there is heat transfer between the low-pressure chamber and the high-pressure chamber.

[0048] For the high-pressure chamber, heat transfer to the low-pressure chamber side will cause heat dissipation, affect the refrigeration effect and cycle efficiency, and increase energy consumption, and for the low-pressure chamber, it will cause the temperature of the low-pressure low-temperature medium to rise, which will reduce the intake volume efficiency and also reduce the compressor efficiency.

[0049] In summary, the heat transfer between the low-pressure chamber and the high-pressure chamber will reduce the working performance of the compressor.

[0050] Based on this, the present application provides a shell, and a heat insulation part is arranged between the high-pressure part and the low-pressure part of the shell, so that the heat transfer between the low-pressure part and the high-pressure part can be reduced, the heat transfer between the low-pressure chamber and the high-pressure chamber is reduced, and the working performance of the compressor is improved.

[0051] The compressor of the present application can be applied to a vehicle, which can be a fuel automobile, a gas automobile or a new energy automobile, and the new energy automobile can be a pure electric automobile, a hybrid electric automobile or a range extended automobile.

[0052] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the vehicle 300 provided for some embodiments of the present application is shown.The vehicle 300 is internally provided with the compressor 200, and the compressor 200 is applied to the thermal management system of the vehicle 300, which can realize passenger compartment temperature regulation, engine system temperature regulation, electric drive system temperature regulation, battery device temperature regulation, vehicle-mounted refrigerator temperature regulation, etc.

[0053] The compressor 200 and the vehicle 300 according to the embodiments of the utility model are described below with reference to Figures 1-4

[0054] As shown in Figure 1 and Figure 2 , the present application provides a shell 100, which is applied to the compressor 200, i.e. the shell 100 is the shell 100 of the compressor 200.

[0055] The shell 100 comprises a high-pressure part 10, a low-pressure part 20, and a heat insulation part 30. The high-pressure part 10 defines a high-pressure chamber. The low-pressure part 20 defines a low-pressure chamber. The heat insulation part 30 is located between the high-pressure part 10 and the low-pressure part 20. At least part of the heat insulation part 30 participates in defining the high-pressure chamber and the low-pressure chamber, so as to reduce heat transfer between the low-pressure part 20 and the high-pressure part 10.

[0056] The shell 100 can be configured as an integrated shell 100. The shell 100 can be divided into the high-pressure part 10, the heat insulation part 30, and the low-pressure part 20 arranged in sequence. The heat insulation part 30 can be used to reduce heat transfer between the low-pressure part 20 and the high-pressure part 10. The shell 100 can also be configured as a split shell 100. A first shell 100 and a second shell 100 are detachably connected. The first shell 100 defines the low-pressure part 20. The second shell 100 defines the high-pressure part 10. A third shell 100 can be arranged between the first shell 100 and the second shell 100. The third shell 100 defines the heat insulation part 30, so as to reduce heat transfer between the low-pressure part 20 and the high-pressure part 10 through the heat insulation part 30. Of course, the heat insulation part 30 can also be integrated into the first shell 100 or the second shell 100.

[0057] Specifically, the inner wall of the high-pressure part 10 defines the high-pressure chamber. The inner wall of the low-pressure part 20 defines the low-pressure chamber. The heat insulation part 30 is located between the high-pressure part 10 and the low-pressure part 20. Part of the inner wall of the heat insulation part 30 can participate in defining the high-pressure chamber. Another part of the inner wall of the heat insulation part 30 can participate in defining the low-pressure chamber. Through the heat insulation performance of the heat insulation part 30, heat transfer between the low-pressure part 20 of the shell 100 and the high-pressure part 10 of the shell 100 is reduced.

[0058] It should be noted that the heat insulation part 30 arranged between the low-pressure part 20 and the high-pressure part 10 can reduce heat transfer between the high-pressure part 10 and the low-pressure part 20 of the shell 100, so as to maintain the pressure and temperature stability of the low-pressure chamber and the high-pressure chamber.

[0059] The high-pressure chamber contains high-temperature and high-pressure medium, and the low-pressure chamber contains low-temperature and low-pressure medium. Through the heat insulation part 30, heat transfer between the high-pressure part 10 and the low-pressure part 20 of the shell 100 is reduced. The energy loss of the high-temperature and high-pressure medium in the high-pressure chamber is reduced. Heat dissipation is reduced. The energy efficiency of the compressor 200 is improved. The influence of high temperature on the low-pressure chamber is reduced. The thermal expansion of the low-temperature and low-pressure medium is reduced. The intake volume efficiency is improved. The energy efficiency of the compressor 200 is improved. The operation stability of the compressor 200 is improved.

[0060] According to the shell 100 of the embodiment of the present application, by arranging the heat insulation part 30 between the high-pressure part 10 and the low-pressure part 20 of the shell 100, the heat exchange between the high-pressure chamber and the low-pressure chamber through the shell 100 can be reduced, so that the heat dissipation of the high-temperature and high-pressure medium in the high-pressure chamber can be reduced, the temperature regulation effect and the energy efficiency of the compressor 200 can be improved, the influence of the high temperature on the low-pressure chamber can be reduced to improve the intake volume efficiency, the energy efficiency of the compressor 200 can be improved, the working performance of the compressor 200 can be improved, and the service life of the compressor 200 can be prolonged.

[0061] In combination with Figure 1 and Figure 2 It is shown that, according to some embodiments of the present application, the heat insulation part 30 is detachably arranged in the low-pressure part 20, or the heat insulation part 30 and the low-pressure part 20 are made of the same material, and the heat insulation part 30 and the low-pressure part 20 are integrally formed.

[0062] Specifically, as shown in Figure 1 , in some embodiments, the heat insulation part 30 and the low-pressure part 20 are an integrally formed piece, and the heat insulation part 30 and the low-pressure part 20 are made of the same material, so as to reduce the difficulty of integrally forming the low-pressure part 20 and the heat insulation part 30, and the heat insulation part 30 can also effectively reduce the heat transfer between the low-pressure part 20 and the high-pressure part 10, reduce the heat transfer on the shell 100, and improve the heat resistance effect between the low-pressure chamber and the high-pressure chamber; as shown in Figure 2 , in other embodiments, the heat insulation part 30 and the low-pressure part 20 are arranged separately, and the heat insulation part 30 and the low-pressure part 20 can be made of the same material or different materials, so as to reduce the heat transfer between the low-pressure part 20 and the high-pressure part 10, and improve the heat resistance effect between the low-pressure chamber and the high-pressure chamber.

[0063] Therefore, in the embodiment in which the heat insulation part 30 and the low-pressure part 20 are integrally formed, the assembly difficulty can be reduced, the production efficiency can be improved, and the energy efficiency of the compressor 200, the stability and reliability of the compressor 200 can be improved; and in the embodiment in which the heat insulation part 30 and the low-pressure part 20 are detachably arranged, the cost of the shell 100 can be reduced, and the energy efficiency of the compressor 200, the stability and reliability of the compressor 200 can be improved.

[0064] According to some embodiments of the present application, the sum of the axial dimensions of the low-pressure part 20 and the heat insulation part 30 is L1, the axial dimension of the heat insulation part 30 is L2, and 0.2≤L2 / L1≤0.8 is satisfied.

[0065] Specifically, in the embodiment where the low-pressure part 20 and the heat-insulating part 30 are separately arranged, the sum of the sizes of the low-pressure part 20 and the heat-insulating part 30 is greater than the size of the heat-insulating part 30. The axial size of the heat-insulating part 30 can be 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, etc. of the total size. In the embodiment where the low-pressure part 20 and the heat-insulating part 30 are integrally formed, the material of the low-pressure part 20 and the heat-insulating part 30 is the same, i.e., L1 is equal to L2, and the ratio between the two is 1.

[0066] In this way, the axial size of the heat-insulating part 30 can be more reasonable. On the one hand, the heat-insulating effect of the heat-insulating part 30 in blocking heat transfer between the low-pressure part 20 and the high-pressure part 10 can be improved. On the other hand, the heat transfer between the shell 100 and the low-temperature and low-pressure medium in the low-pressure chamber and between the shell 100 and the high-temperature and high-pressure medium in the high-pressure chamber can be less. The heat dissipation of the high-temperature and high-pressure medium in the high-pressure chamber and the thermal expansion of the low-temperature and low-pressure medium in the low-pressure chamber can also be reduced. The energy efficiency of the compressor 200 can be improved, and the working stability and reliability of the compressor 200 can be improved.

[0067] According to some embodiments of the present application, the heat-insulating part 30 is configured as any one of a plastic part, a ceramic part, and a plastic-ceramic composite part.

[0068] In some embodiments, the heat-insulating part 30 can be configured as a plastic part, such as polystyrene (EPS), polyurethane (PU), etc. Under the premise of achieving heat blocking between the high-pressure part 10 and the low-pressure part 20, the weight of the shell 100 can also be reduced, and the thermal efficiency of the compressor 200 can be improved.

[0069] In some embodiments, the heat-insulating part 30 can be configured as a ceramic part, such as microporous ceramic. 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 a high-temperature environment, thereby prolonging the service life of the shell 100. On the other hand, the heat-insulating ceramic material usually has a large number of small pores, which can effectively block the transfer of heat, thereby achieving the effect of heat insulation.

[0070] In addition, some heat-insulating ceramic materials can also be designed and formulated in a special way, such as by coating a layer of glaze containing aluminum or other materials with high reflectivity on the surface, to reduce the heat radiation absorption capacity of the heat-insulating part 30, and further improve its heat-insulating performance.

[0071] In some embodiments, the heat-insulating part 30 adopts a ceramic-plastic composite part, which is a composite material integrating the characteristics of ceramic and plastic, and has excellent heat-insulating performance and plasticity.

[0072] Thus, the high melting point, high hardness and good chemical stability of the ceramic and the light weight, easy processing and corrosion resistance of the plastic can be combined together through special processing technology. The thermal insulation part 30 can be provided with better thermal insulation effect and higher mechanical strength.

[0073] It can be understood that, due to the high melting point of the ceramic material itself, the composite thermal insulation part can maintain stable performance in a high temperature environment and is not easy to melt or deform. At the same time, the addition of the plastic component gives the composite thermal insulation part certain flexibility and plasticity, making it easier to process and install.

[0074] In summary, the thermal insulation part 30 constructed as a plastic part, a ceramic part or a plastic-ceramic composite part can improve the thermal insulation effect of the shell 100, improve the thermal efficiency of the compressor 200, improve the energy efficiency and working stability of the compressor 200, and reduce the weight of the shell 100 and the difficulty of arrangement.

[0075] It should be noted that, in the embodiment in which the thermal insulation part 30 is integrally formed with the low-pressure part 20, a sealing structure is provided between the thermal insulation part 30 and the high-pressure part 10, and the thermal insulation part 30 and the high-pressure part 10 can be connected by fasteners after the low-pressure side component 210 and the high-pressure side component 220 are assembled. In the embodiment in which the thermal insulation part 30 is detachably connected with the low-pressure part 20, a sealing structure is provided between the low-pressure part 20 and the thermal insulation part 30, and between the thermal insulation part 30 and the high-pressure part 10, and the low-pressure part 20, the thermal insulation part 30 and the high-pressure part 10 can be further assembled by fasteners after the low-pressure side component 210 and the high-pressure side component 220 are assembled.

[0076] It can be understood that the high-pressure part 10 of the shell 100 needs to withstand a large pressure, while the low-pressure part 20 withstands a smaller pressure. The present application separately provides the thermal insulation part 30, or integrally forms the thermal insulation part 30 with the low-pressure part 20. For the high-pressure part 10 that needs to withstand a large pressure, the existing structure is maintained, and the structural strength and reliability of the shell 100 are also considered, thereby improving the working stability and reliability of the compressor 200.

[0077] As shown in Figure 3 The present application provides a compressor 200, which comprises a shell 100, a low-pressure side component 210 and a high-pressure side component 220. The low-pressure side component 210 is arranged in a low-pressure chamber, and the high-pressure side component 220 is arranged in a high-pressure chamber.

[0078] Specifically, the housing 100 defines a receiving space, which can be divided into a low-pressure chamber and a high-pressure chamber, corresponding to the low-pressure side components 210 and the high-pressure side components 220 of the compressor 200, the low-pressure side components 210 are arranged in the low-pressure chamber, and the high-pressure side components 220 are arranged in the high-pressure chamber.

[0079] Wherein, the low-pressure portion 20 of the housing 100 can be provided with a low-pressure inlet, and the high-pressure portion 10 can be provided with a high-pressure outlet. The low-temperature and low-pressure medium enters the low-pressure chamber from the low-pressure inlet, flows through the low-pressure side components 210 and the high-pressure side components, and flows into the high-pressure chamber. Under the action of the low-pressure side components 210 and the high-pressure side components 220 (such as the moving scroll 230 and the stationary scroll, the driving motor, the high-pressure side bearing, the low-pressure side bearing, etc.), the high-temperature and high-pressure medium is formed after compression work, and is discharged from the high-pressure outlet. The temperature of the high-pressure chamber is higher than that of the low-pressure chamber. The low-pressure portion 20 defines the low-pressure chamber, and the high-pressure portion 10 defines the high-pressure chamber. As a result, at least part of the heat of the high-temperature and high-pressure medium in the high-pressure chamber is transferred to the high-pressure portion 10. The temperature difference between the high-pressure portion 10 and the low-pressure portion 20 is large, and heat transfer phenomenon exists between the low-pressure portion 20 and the high-pressure portion 10 of the housing 100.

[0080] Based on this, the compressor 200 of the embodiment of the present application adopts the housing 100 in the above-mentioned embodiment. The low-pressure portion 20 and the high-pressure portion 10 of the housing 100 are provided with a heat insulation portion 30. The heat insulation portion 30 can block the heat transfer of the housing 100 to reduce the heat dissipation of the high-pressure chamber and the temperature rise of the low-pressure chamber caused by the housing 100.

[0081] 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 to improve 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 to improve the intake volume efficiency, thereby further improving the energy efficiency of the compressor 200, improving the working stability and reliability of the low-pressure side components 210 in the low-pressure chamber, prolonging the service life of the compressor 200, and improving the overall performance of the compressor 200.

[0082] In combination with Figure 2 and Figure 3 As shown, according to some embodiments of the present application, the compressor 200 further comprises a moving scroll 230 located between the low-pressure chamber and the high-pressure chamber, and at least part of the moving scroll 230 is located within the radial projection profile range of the heat insulation portion 30 in the compressor 200.

[0083] Specifically, during the operation of the compressor 200, the medium needs to flow through the static scroll and the cooperating dynamic scroll 230 to compress the work, the dynamic scroll 230 is located on the junction area of the low-pressure chamber and the high-pressure chamber, the axial one side of the dynamic scroll 230 is the high-pressure chamber, and the axial other side of the dynamic scroll 230 is the low-pressure chamber, and at least part of the dynamic scroll 230 is located in the projection profile range of the heat insulation part 30 in the radial direction of the compressor 200, so that the heat insulation part 30 can be arranged adjacent to the junction area of the high-pressure chamber and the low-pressure chamber, the arrangement position of the heat insulation part 30 is more reasonable, and the heat transfer generated on the shell 100 can be further reduced, so as to improve the energy efficiency and working stability of the compressor 200.

[0084] In combination Figure 3 As shown, according to some embodiments of the present application, the side of the dynamic scroll 230 facing the high-pressure chamber and / or the side of the dynamic scroll 230 facing the low-pressure chamber is provided with a heat insulation part to reduce the heat transfer between the low-pressure chamber and the high-pressure chamber.

[0085] Specifically, the heat insulation part can be configured as a heat insulation material part with the same profile as the dynamic scroll 230, and is arranged in close contact with the side surface of the dynamic scroll 230 facing the low-pressure chamber or the side surface of the dynamic scroll 230 facing the high-pressure chamber. The heat insulation part can also be configured as a heat insulation sleeve and is sleeved on the dynamic scroll 230 to reduce the heat transfer between the low-pressure chamber and the high-pressure chamber in the shell 100, thereby further improving the thermal efficiency of the compressor 200 and improving the energy efficiency of the compressor 200.

[0086] According to some embodiments of the present application, the heat insulation part is configured as a heat insulation coating and is coated on the surface of the dynamic scroll 230.

[0087] Specifically, the heat insulation coating is coated on the side surface of the dynamic scroll 230 facing the low-pressure chamber, or the heat insulation coating is coated on the side surface of the dynamic scroll 230 facing the high-pressure chamber, or the heat insulation coating is coated on the surface of the dynamic scroll 230 facing the high-pressure chamber and facing the low-pressure chamber.

[0088] Therefore, under the premise of ensuring the heat insulation effect of the heat insulation part to improve the energy efficiency of the compressor 200, the heat insulation part can be directly coated on the dynamic scroll 230, which can reduce the cost of the heat insulation part and the difficulty of arranging the heat insulation part.

[0089] It should be noted that the heat insulation coating can be selected as a conductive insulation type heat insulation coating, which realizes heat insulation through low thermal conductivity and high thermal resistance, or a radiation type heat insulation coating, such as adding fillers with strong infrared radiation capacity in the coating to disperse the absorbed energy in the form of radiation, or a composite heat insulation coating of the conductive insulation type and the radiation type.

[0090] It can be understood that the heat insulation coating is preferably coated on the side of the moving scroll 230 facing the low-pressure chamber, which can also reduce the friction between the moving scroll 230 and the surrounding components, reduce the probability of the heat insulation coating falling off or failing, improve the heat insulation stability and reliability of the heat insulation member.

[0091] As shown in Figure 4 , the present application provides a vehicle 300, comprising the compressor 200 in the above embodiments.

[0092] Specifically, the vehicle 300 has a thermal management system, which can be used to adjust the passenger cabin temperature, the engine system temperature, the electric drive system temperature, the battery device temperature, etc., and the above-mentioned compressor 200 is used in the thermal management system. Under the premise of realizing temperature regulation, the compressor 200 has higher energy efficiency and higher working stability, which can effectively improve the driving comfort of the vehicle 300, reduce the energy consumption of the vehicle 300, improve the fuel economy, or improve the cruising range of the new energy vehicle 300.

[0093] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the shell 100 of the compressor 200 in the embodiments of the present application comprises a low-pressure part 20, a high-pressure part 10, and a heat insulation part 30 between the low-pressure part 20 and the high-pressure part 10. The heat insulation part 30 can be configured as a plastic part, a ceramic part or a plastic-ceramic composite part, and the heat insulation part 30 can be integrally formed with the low-pressure part 20.
