[0062] This application discloses a compressor. As understood, a compressor is a driven fluid machine that can draw in low-pressure gas and elevate it to high-pressure gas for discharge. Depending on different working principles and structural designs, compressors can be classified into various types, such as reciprocating compressors, screw compressors, or centrifugal compressors. The compressor disclosed in this application can be a reciprocating compressor, a screw compressor, or a centrifugal compressor, etc., and this application does not limit its application in this regard. Furthermore, the compressor disclosed in this application can be used in vehicles as described below, and can also be used in equipment such as air conditioners. This application does not limit the type of equipment to which the compressor is applied.

[0063] The structure of the compressor proposed in this application will be explained and illustrated below with examples:

[0064] Please refer to the reference. Figures 1 to 4 In one embodiment of this application, the compressor 100 includes a first housing 11, a second housing 12, a cover 13, a compression section 20, a motor 30, an electronic control device 40, and a heater 50; the cover 13 and one side of the first housing 11 define a receiving cavity 100c, and the electronic control device 40 is disposed in the receiving cavity 100c; the compression section 20 and the motor 30 are disposed in the area between the other side of the first housing 11 and the second housing 12, the motor 30 is drivenly connected to the compression section 20, and the electronic control device 40 is electrically connected to the motor 30; the compressor 100 is provided with a refrigerant interface 100a communicating with the compression section 20 and a circuit interface 100b electrically connected to the electronic control device 40; the heater 50 has a liquid... The liquid flow channel 50a has an inlet 50a1 and an outlet 50a2. The heater 50 includes one or at least two heating elements 51. At least a portion of the heating elements 51 is disposed in the receiving cavity 100c. The heating element 51 includes a base 511 and a heating part 512. The base 511 has a heating flow channel 511a. The heating flow channels 511a of one or at least two heating elements 51 constitute at least a portion of the liquid flow channel 50a. The heating part 512 is provided on the outer peripheral wall of the base 511. The heating part 512 extends circumferentially along the base 511. The heating part 512 is electrically connected to the electronic control device 40. A heat insulation structure 60 is provided between the heater 50 and the electronic control device 40.

[0065] The first housing 11 can be used to collect low-pressure gas from the outside and supply it to the compression unit 20. The side of the first housing 11 facing the second housing 12 can be recessed to form an opening. In this case, the compression unit 20 can be located outside the opening, and the opening can be directly connected to the compression unit 20 through its opening; alternatively, the compression unit 20 can be directly disposed within the opening, ensuring that the opening can communicate with the compression unit 20; the motor 30 can be disposed within the opening. Alternatively, the side of the first housing 11 facing the second housing 12 can form a closed cavity. In this case, the compression unit 20 can be located outside the closed cavity, and the closed cavity can be connected to the compression unit 20 through an additional gas supply pipe; the motor 30 can be disposed within the closed cavity or outside the closed cavity. Furthermore, the end of the first housing 11 facing away from the second housing 12, i.e., the end facing the housing cover 13, can also be used to enclose with the housing cover 13 to form a receiving cavity 100c for accommodating the electronic control device 40 and the heater 50. The side of the first housing 11 facing the cover 13 may also be recessed to form an opening, which, together with the cover 13, forms a receiving cavity 100c. Alternatively, the side of the first housing 11 facing the cover 13 may not have an opening, and the receiving cavity 100c may be formed directly by the end face of the housing and the cover 13.

[0066] The second housing 12 can be used to collect the high-pressure gas output from the compression unit 20 and discharge it to equipment that requires high-pressure gas, such as a condenser. The side of the second housing 12 facing the first housing 11 can be recessed to form an open cavity. In this case, the compression unit 20 can be located outside the open cavity, communicating with it through the opening; alternatively, the compression unit 20 can be directly placed inside the open cavity, ensuring communication. Alternatively, the side of the second housing 12 facing the first housing 11 can form a closed cavity. In this case, the compression unit 20 can be located outside the closed cavity, communicating with it through an additional gas supply pipe. Therefore, the area between the first housing 11 and the second housing 12 described above can be understood as the area defined by the opposing sidewalls of the first housing 11 and the second housing 12 in the arrangement direction of the first housing 11 and the second housing 12, i.e., the first direction described below. At this time, there are cases where the compression part 20 is located outside the first housing 11 and the second housing 12 and between the first housing 11 and the second housing 12, and at least a portion of the motor 30 is located inside the first housing 11; there are also cases where both the compression part 20 and the motor 30 are located outside the first housing 11 and the second housing 12 and between the first housing 11 and the second housing 12; and there are also cases where the first housing 11 and the second housing 12 enclose a closed cavity, and both the compression part 20 and the motor 30 are located inside the closed cavity.

[0067] As described above, the cover 13 can be used to enclose the first housing 11 to form a receiving cavity 100c. The side of the cover 13 facing the first housing 11 may be recessed to form an opening, through which the cover 13 encloses the first housing 11 to form the receiving cavity 100c. Alternatively, the side of the cover 13 facing the first housing 11 may not have an opening, and the cover 13 may directly enclose the first housing 11 through its end face to form the receiving cavity 100c.

[0068] The compression section 20 can be used to compress gas to convert low-pressure gas into high-pressure gas. The structure of the compression section 20 can be determined by the type of compressor 100. For example, when the compressor 100 is a reciprocating compressor 100, the compression section 20 may include a cylinder and a piston; when the compressor 100 is a screw compressor 100, the compression section 20 may include male and female rotors and a cylinder assembly; when the compressor 100 is a scroll compressor 100, the compression section 20 may include a moving scroll plate and a stationary scroll plate; when the compressor 100 is a rolling rotor compressor 100, the compression section 20 may include an eccentric rotor and vanes. In one embodiment, the compression section 20 includes a housing and a scroll plate assembly, the scroll plate assembly including a moving scroll plate and a stationary scroll plate, the scroll plate assembly being disposed within the housing, the housing being disposed in the region between the other side of the first housing 11 and the second housing 12, and the housing being connected to the stationary scroll plate. The outer shell connects the first housing 11 and the second housing 12, and is detachably connected to the stationary vortex disk; alternatively, the outer shell and the stationary vortex disk are integrally formed. In this solution, the outer shell and the stationary vortex disk are integrally formed, that is, the outer shell and the stationary vortex disk are a single structure, with one end of the outer shell connected to the first housing 11 and the other end of the outer shell connected to the second housing 12.

[0069] The motor 30 can be used to provide power to drive the compression unit 20 to compress the gas.

[0070] The electronic control device 40 can be used to control the operation of the motor 30 and the heater 50, such as controlling the start and stop of the motor 30 and adjusting the speed of the motor 30 in the compressor 100, and controlling the start and stop of the heater 50 and adjusting its heating power. The electronic control device 40 may include a circuit board and control chips mounted on that circuit board. The operation of the motor 30 and the heater 50 can be controlled by the same control chip. Alternatively, different control chips can be used to control the motor 30 and the heater 50 separately. In this case, the two control chips can be mounted on the same circuit board or distributed on different circuit boards.

[0071] The heater 50 can be used to heat the heat exchange medium (which can be water, oil, or other media) entering the heating channel 511a, so that it can be delivered to the place where heating is required. For example, when the temperature of a vehicle battery is low, the rate of chemical reaction inside the battery slows down, resulting in a decrease in the battery's charging and discharging efficiency and a decline in battery performance. Therefore, a circulation pipeline can be provided to connect with the heating channel 511a, so that the heat exchange medium can be heated by the heater 50 after entering the heating channel 511a, so that it reaches the required temperature and is then delivered to the battery through the circulation pipeline, thereby heating the battery. Of course, heating the battery is only an exemplary explanation. The heat exchange medium heated by the heater 50 in this solution can also be delivered to other locations in the vehicle, such as the engine and seats. The liquid flow channel 50a in the heater 50 can be entirely composed of the heating flow channel 511a of the base 511 in the heating body 51. At this time, the inlet 50a1 for supplying the heat exchange medium into the heater 50 and the outlet 50a2 for supplying the heat exchange medium out of the heater 50 can be provided in the base 511. Of course, the heater 50 can also further include an inlet connector 53 and an outlet connector 54, as described below. In this case, the heating flow channel 511a of the base 511 in the heating element 51 can constitute the liquid flow portion, and the inlet channel in the inlet connector 53 and the outlet channel in the outlet connector 54 can also constitute the liquid flow portion. The inlet 50a1 and the outlet 50a2 can be respectively provided in the inlet connector 53 and the outlet connector 54. Furthermore, the heater 50 includes one or at least two heating elements 51; that is, the number of heating elements 51 can be one, or two or more. When the number of heating elements 51 is at least two, the at least two heating elements 51 can be arranged in series, in parallel, or a mixture of partially series and partially parallel connections. Furthermore, the base 511 in the heating element 51 can be a tubular structure, constituting a tubular heating element 51. Moreover, in a cross-section perpendicular to the extending direction of the heating channel 511a, the cross-section of the base 511 can be a continuous and complete annular cross-section, so that the base 511 can have a complete annular wall in the circumferential direction. This reduces the possibility of leakage at the joints due to vibration or collision during long-term use of the compressor 100, compared to using several parts to enclose and form the heating channel 511a in the circumferential direction. Additionally, the heating portion 512 in the heating element 51 can be a thick film, or it can be an electromagnetic induction coil; this application does not limit the type of heating portion 512. In order to increase the heating area of ​​the heating element 51, reduce the volume of the heating element 51, and improve the convenience of arranging the heating element 51, in one embodiment, the heating element 51 can be a thick film.At this time, the substrate 511 can be made of metal. When the heating element 51 uses a thick film heating method, a thick film is printed on the substrate 511. At the same time, it also facilitates the efficient transfer of heat through the substrate 511 by the heating part 512 located on the outside of the substrate 511, thereby improving the heating efficiency of the heat exchange medium located in the heating channel 511a. In addition, the heating part 512 is provided on the outer peripheral wall of the substrate 511 and extends circumferentially along the substrate 511. That is, the heating part 512 can completely surround the outer periphery of the substrate 511, or it can surround a part of the outer periphery of the substrate 511. For example, the heating part 512 continuously surrounds 3 / 4 of the outer peripheral wall of the substrate 511; or, the heating part 512 is composed of multiple small heating elements, which are spaced apart along the outer periphery of the substrate 511. In addition, it should be noted that the heating element 51 in the heater 50 integrated in the compressor 100 proposed in this application can be either a tubular heating element 51 as described above or a plate-shaped heating element 51. This application does not limit the type of heater 50.

[0072] The refrigerant interface 100a may include an air inlet 100a1 and an air outlet 100a2. The air inlet 100a1 may be located in the first housing 11 for the discharge of external pressurized gas. The air outlet 100a2 may be located in the second housing 12 for the discharge of high-pressure gas. The electrical interface 100b can be used for electrical connection with an external source, such as a vehicle. The electrical interface 100b includes a high-voltage connector 100b1 and a low-voltage connector 100b2, which may be located in the first housing 11 for electrical connection with the electronic control device 40.

[0073] The heat insulation structure 60 can be used to at least partially block the heat generated by the heater 50, so as to minimize the heat transfer from the heater 50 to the electronic control device 40, thereby reducing the possibility of damage to the electronic control device 40 due to high temperature. The heat insulation structure 60 is disposed between the heater 50 and the electronic control device 40, including both cases where a portion of the heat insulation structure 60 is located between the heater 50 and the electronic control device 40, and cases where the entire heat insulation structure 60 is located between the heater 50 and the electronic control device 40. Furthermore, the heat insulation structure 60 can be a vacuum cavity structure as described below, or it can be a heat insulation element 61. Therefore, this application does not limit the type of heat insulation structure 60.

[0074] The compressor 100 in this application includes a first housing 11, a second housing 12, a cover 13, a compression section 20, a motor 30, an electronic control device 40, and a heater 50. The electronic control device 40 is located in the receiving cavity 100c of the compressor 100 and is electrically connected to the motor 30. The heater 50 includes one or at least two heating elements 51, at least a portion of which is located in the receiving cavity 100c. Each heating element 51 includes a base 511 and a heating section 512, which is electrically connected to the electronic control device 40. In other words, the electronic control device 40 and the heater 50 are both integrated on the compressor 100, allowing the motor 30 and the heater 50 to share a single electronic control device 40. This shortens the wiring path between the heater 50 and the electronic control device 40, resulting in a highly integrated compressor 100. Meanwhile, the heating element 512 in the heater 50 is also configured to extend circumferentially along the base 511. Compared to single-plane heating, the volume of the heating element 51 in the heater 50 of this solution can be designed to be smaller for the same heating area, resulting in a more compact overall structure of the heater 50. This reduces space occupation while meeting the required heating effect. Therefore, the compressor 100 in this solution, on the one hand, shortens the wiring path of the electrical connection between the heater 50 and the electronic control device 40 by integration, and on the other hand, with the optimized compact structure of the heater 50 itself, can significantly reduce the volume of the compressor 100, thereby improving the space utilization of the vehicle. In addition, because the compact heater 50 in this solution can more concentratedly heat the heat exchange medium in the heating channel 511a in the circumferential direction, the temperature of the heater 50 during operation is higher. Therefore, in this design scenario, the compressor 100 in this solution further provides a heat insulation structure 60 between the heater 50 and the electronic control device 40, so that the heat generated by the heater 50 during operation can be blocked from being transferred to the electronic control device 40, so as to minimize the transfer of heat generated by the heater 50 to the electronic control device 40, thereby reducing the possibility of damage to the electronic control device 40.

[0075] Please refer to the reference. Figure 2 and Figure 3 In one embodiment of this application, the receiving cavity 100c includes a first cavity 11a and a second cavity 13a, the electronic control device 40 is disposed in the first cavity 11a, and at least a portion of the heating element 51 is disposed in the second cavity 13a.

[0076] The first cavity 11a can be entirely disposed on the first housing 11, or entirely disposed on the housing cover 13, or partially disposed on the first housing 11 and partially disposed on the housing cover 13, with the first housing 11 and housing cover 13 enclosing each other to form the first cavity 11a. Similarly, the second cavity 13a can be entirely disposed on the second housing 12, or entirely disposed on the housing cover 13, or partially disposed on the first housing 11 and partially disposed on the housing cover 13, with the first housing 11 and housing cover 13 enclosing each other to form the second cavity 13a. Therefore, when the first cavity 11a and the second cavity 13a are simultaneously disposed on the first housing 11 or the housing cover 13, the electronic control device 40 and the heating element 51 can be simultaneously installed on the first housing 11 or the housing cover 13. When the first cavity 11a and the second cavity 13a are respectively disposed on the first housing 11 and the housing cover 13, the electronic control device 40 and the heating element 51 can be respectively installed on the first housing 11 and the housing cover 13. Additionally, the first housing 11 or the cover 13 may be partially located between the first cavity 11a and the second cavity 13a to separate the first cavity 11a and the second cavity 13a. Of course, the first housing 11 or the cover 13 may also not separate the first cavity 11a and the second cavity 13a. Furthermore, the arrangement direction of the cover 13 and the first housing 11 is defined as the first direction. In this case, the first cavity 11a and the second cavity 13a can be arranged along the first direction, or they can be arranged along a direction intersecting the first direction. It should be noted that when the compressor 100 is in normal installation and use, with the ground as a reference, the first direction can be a horizontal direction. Of course, in other embodiments, the first direction can also be a vertical direction or other directions.

[0077] In this embodiment, the electronic control device 40 and the heating element 51 are respectively located in the first cavity 11a and the second cavity 13a, so that they can be arranged in separate sections, which helps to further reduce the possibility of heat generated by the heater 50 during operation being transferred to the electronic control device 40.

[0078] Please refer to the reference. Figure 2 and Figure 3 In one embodiment of this application, the first housing 11 is provided with a first cavity 11a, the first cavity 11a having a first opening 11a1, and the electronic control device 40 is disposed inside the first housing 11; the cover 13 is provided with a second cavity 13a, and at least a portion of the heating element 51 is disposed inside the cover 13.

[0079] The second cavity 13a may have a second opening 13a1, as described below, through which the heater 50 is mounted. Alternatively, the second cavity 13a may be connected to the first cavity 11a, with the heater 50 mounted at the connection point between the second cavity 13a and the first cavity 11a. Alternatively, the cover 13 may be divided into two parts, with the heater 50 mounted in one part, and then the parts are closed to form a single unit. Furthermore, the second cavity 13a may be a vacuum cavity, as described below, or it may be a non-vacuum cavity.

[0080] In this embodiment, a first cavity 11a is provided by a first housing 11, and a second cavity 13a is provided by a cover 13, so that the electronic control device 40 and the heating element 51 can be distributed on two separate components. At this time, the contact thermal resistance between the first housing 11 and the cover 13 affects heat transfer, which further helps to reduce the heat generated by the heater 50, located at least partially within the cover 13, from being transferred to the electronic control device 40 located within the first housing 11. Simultaneously, forming the first cavity 11a and the second cavity 13a separately by two parts simplifies their structure and improves the ease of processing and molding.

[0081] Please refer to the reference. Figure 2 and Figure 3 In one embodiment of this application, the second cavity 13a has a second opening 13a1, the compressor 100 also includes a cover plate 14, the cover plate 14 covers the second opening 13a1, and the heater 50 is disposed on the cover plate 14.

[0082] The second opening 13a1 can be located on one side of the cover 13 in the first direction, that is, on the side of the cover 13 facing away from the first housing 11. Alternatively, it can be located on one side of the cover 13 in the second direction, or on the side facing a third direction, where the second direction, the third direction, and the first direction intersect each other. When the first direction is horizontal as described above, the second direction can be vertical, and the third direction can be another horizontal direction. Furthermore, the heater 50 is located on the cover plate 14, which can be through the cover plate 14, such that part of the heater 50 is located inside the second cavity 13a, and the other part is located outside the second cavity 13a. Alternatively, the heater 50 can be installed on the side of the cover plate 14 facing the second cavity 13a, so that the heater 50 is completely located inside the second cavity 13a. Moreover, the connection between the cover plate 14 and the cover 13 can be achieved by adhesive 13d1, as described below. Of course, threaded connection, snap-fit ​​connection or welding connection can also be used. This application does not limit the connection method between cover plate 14 and shell cover 13.

[0083] In this embodiment, the heater 50 is mounted on the cover plate 14. The cover plate 14 is spaced from the first housing 11 by a cover 13, which further increases the contact thermal resistance, thus affecting heat transfer and further reducing the possibility of heat generated by the heater 50 being transferred to the electronic control device 40 located inside the first housing 11. Simultaneously, the cover plate 14 is also in contact with the outside air, allowing the heat generated by the heater 50 to be dissipated as much as possible into the outside air, further reducing the potential impact of the heat generated by the heater 50 on the electronic control device 40.

[0084] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, at least one of the shell cover 13 and the cover plate 14 is provided with a groove 13d, the groove 13d extending circumferentially along the second opening 13a1; an adhesive 13d1 is provided in the groove 13d to connect the cover plate 14 and the shell cover 13.

[0085] The adhesive 13d1 is liquid when applied and solidifies thereafter to bond the cover 13 and the cover plate 14. At least one of the cover 13 and the cover plate 14 has a groove 13d; that is, the cover 13 may have a groove 13d; the cover 14 may have a groove 13d; or both the cover 13 and the cover plate 14 may have grooves 13d. In this case, the grooves 13d on the cover 13 and the cover 14 may be connected relative to each other, or they may be staggered and spaced apart. Furthermore, the groove 13d may be an annular groove surrounding the second opening 13a1, or it may include multiple sub-grooves spaced around the second opening 13a1 at intervals.

[0086] In this embodiment, the groove 13d provides space for the adhesive 13d1, allowing it to be stably positioned during application and effectively connect the cover 13 and the cover plate 14 after curing. Using adhesive 13d1 to connect the cover 13 and the cover plate 14 provides both a stable connection and a good seal, reducing the possibility of external moisture entering the cavity 100c and causing a short circuit to electrical components. Furthermore, when the second cavity 13a is configured as a vacuum cavity as described below, using adhesive 13d1 to connect the cover 13 and the cover plate 14 facilitates vacuuming of the second cavity 13a and improves its sealing performance. For example, while the adhesive 13d1 between the cover plate 14 and the shell cover 13 is still wet, the heater 50, cover plate 14, and shell cover 13 can be placed as a whole into a vacuum chamber for vacuuming. After the adhesive 13d1 dries, a vacuum will be formed inside the second chamber 13a. Furthermore, using adhesive 13d1 for connection achieves two functional effects with the same structure, namely connection and sealing, thus simplifying the connection structure between the cover plate 14 and the shell cover 13.

[0087] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the shell cover 13 is provided with a groove 13d, and the cover plate 14 is provided with a flange 141. The flange 141 is inserted into the groove 13d, and the adhesive 13d1 is located between the groove wall of the groove 13d and the flange 141.

[0088] The flange 141 can be formed by bending the edge of the cover plate 14 towards the shell cover 13. When the groove 13d is annular as described above, the flange 141 can also extend circumferentially along the cover plate 14 to form an annular shape to fit into the groove 13d. Alternatively, when the groove 13d includes multiple sub-grooves and is arranged circumferentially around the first opening 11a1 as described above, the flange 141 can also be configured to include multiple sub-plates, with one sub-plate corresponding to one sub-groove.

[0089] In this embodiment, the groove 13d is provided on the cover 13, and the wall thickness of the cover 13 is greater than that of the cover plate 14, which helps to improve the setting of the groove 13d and ensure the strength of the cover plate 14. Furthermore, a flange 141 is provided on the cover plate 14 to be inserted into the groove 13d, which can increase the contact area with the adhesive 13d1 located in the groove 13d, thereby further improving the stability and sealing effect of the connection between the cover plate 14 and the cover 13.

[0090] Please refer to the reference. Figures 1 to 4In one embodiment of this application, the first cavity 11a and the second cavity 13a can be arranged along the first direction, and the second opening 13a1 can be arranged facing one side in the second direction; the number of heating elements 51 can be two, and the two heating elements 51 can be arranged side by side in the third direction; the heater 50 can also include a connector 52, which is disposed in the second cavity 13a. The connector 52 is provided with a liquid flow channel 52a, which constitutes part of the liquid flow channel 50a and is connected to the heating flow channel 511a.

[0091] The connector 52 can be used to connect the same end of two heating elements 51 so that the heating channels 511a within the two heating elements 51 can be connected. The connector 52 can be a tubular structure. Alternatively, the connector 52 can include two separate parts, for example, a connecting plate and a connecting seat. The connecting plate can be used to connect the base 511 of the two heating elements 51, and the connecting seat can be used to enclose the connecting plate to form the liquid flow channel 52a.

[0092] In this embodiment, the arrangement direction of the first cavity 11a and the second cavity 13a is set to intersect with the arrangement direction of the two heating elements 51. This improves the compactness of the distribution among the heater 50, the cover 13, and the first housing 11, thereby reducing the overall volume of the compressor 100 and minimizing space occupation. Furthermore, by connecting the two heating elements 51 through the connector 52, the heater 50 can form a U-shaped structure. This allows for maximizing the length of the heating channel 511a within the limited space of the second cavity 13a to meet the required heating effect. Simultaneously, it facilitates the simultaneous outflow of the inlet 50a1 and outlet 50a2 of the heater 50 from the same side, i.e., from the side facing the cover plate 14, thus facilitating connection with the circulation pipeline. Additionally, the connector 52 and the two bases 511 can be an integral structure or separate structures.

[0093] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the substrate 511 may be inserted through the cover plate 14 to extend the length of the substrate 511, thereby facilitating the arrangement of the heating part 512 on the substrate 511.

[0094] In one embodiment of this application, the heater 50 further includes an inlet connector 53 and an outlet connector 54. The inlet connector 53 is connected to one of the two substrates 511, and the outlet connector 54 is connected to the other of the two substrates 511. The inlet connector 53 has an inlet channel 53a, and the outlet connector 54 has an outlet channel 54a. The inlet channel 53a and the outlet channel 54a constitute part of the liquid channel 50a. The inlet channel 53a has an inlet port 50a1, and the outlet channel 54a has an outlet port 50a2.

[0095] In this embodiment, the inlet connector 53 and outlet connector 54 facilitate connection with the circulation pipeline. Alternatively, in the case of including the inlet connector 53 and outlet connector 54, the inlet connector 53 and outlet connector 54 can also be inserted through the cover plate 14. Furthermore, the inlet connector 53 and outlet connector 54 and the corresponding base 511 can be an integral structure, or they can be separate structures.

[0096] In one embodiment of this application, in order to simplify the connection between the heater 50 and the cover plate 14 and improve the sealing performance at the connection, the substrate 511 can be welded to the cover plate 14 when it passes through the cover plate 14; or, the inlet connector 53 and the outlet connector 54 can be welded to the cover plate 14 when they pass through the cover plate 14.

[0097] The above describes the installation of the heater 50 and the electronic control device 40 on the cover 13 and the first housing 11. Next, the structural configuration of the heat insulation structure 60, which provides heat insulation protection for the electronic control device 40, will be further described:

[0098] Please refer to the reference. Figures 2 to 4 ,as well as Figure 6 In one type of insulation, the second cavity 13a can be configured as a vacuum cavity to serve as an insulation structure 60.

[0099] The second chamber 13a can be configured as a vacuum chamber. This can be achieved by placing the chamber into a vacuum chamber while the adhesive 13d1 between the cover plate 14 and the shell cover 13 is still wet, as described above. Alternatively, the shell cover 13 can be split into two parts. After installing the heater 50 inside the shell cover 13, the two parts can be joined together to form a single unit. Vacuuming can then be performed through the evacuation port on one of the parts, and the valve at the evacuation port can be closed after the evacuation is complete.

[0100] In this embodiment, the second cavity 13a of the vacuum is formed into a heat insulation structure 60, which can significantly reduce the heat conduction of the heat generated by the heater 50, thereby reducing the possibility of heat transfer to the electronic control device 40 and improving the heat insulation protection effect of the electronic control device 40.

[0101] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the heating element 51 and the inner wall surface of the shell cover 13 are spaced apart. The gap between the heating element 51 and the inner wall surface of the shell cover 13 is defined as d, which satisfies the relationship: 1 mm ≤ d ≤ 8 mm.

[0102] In this embodiment, the heating element 51 and the inner wall surface of the shell cover 13 are spaced apart, which facilitates the formation of a vacuum cavity. Furthermore, setting the gap d between the heating element 51 and the inner wall surface of the shell cover 13 to 1 mm to 8 mm ensures that the gap is not too small, thus providing insulation between the heating element 51 and the shell cover 13 while also achieving good heat insulation. Simultaneously, it also prevents the gap from being too large, improving the compactness of the distribution between the heater 50 and the shell cover 13. The gap d between the heating element 51 and the inner wall surface of the shell cover 13 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, or 8 mm, or any value within the above range.

[0103] Please refer to the reference. Figure 4 , Figure 6 as well as Figure 7 In one embodiment of this application, the cover 13 is provided with a mounting hole 13b, which communicates with the first cavity 11a and the second cavity 13a; the compressor 100 also includes an electrical connector 70 and a seal 80, the electrical connector 70 passes through the mounting hole 13b and is electrically connected to the heating element 51 and the electrical control device 40, and the seal 80 seals between the electrical connector 70 and the first housing 11.

[0104] In this embodiment, the mounting hole 13b can be provided on the wall surface of the cover 13 for covering the first opening 11a1 of the first cavity 11a, so as to install the electrical connector 70 and thereby realize the electrical connection between the heater 50 and the electrical control device 40. The electrical connector 70 can be provided with a socket, and the heater 50 and the electrical control device 40 can be connected to the sockets on both sides via plugs on the wiring harness. Furthermore, the electrical connector 70 and the wall of the mounting hole 13b can be threaded to improve the stability of the electrical connector 70 on the cover 13. Alternatively, the electrical connector 70 and the wall of the mounting hole 13b can be bonded or interference-fitted. Further, the sealing element 80 can seal between the electrical connector 70 and the cover 13 to ensure a vacuum effect within the first cavity 11a. The sealing element 80 can be made of silicone or rubber to provide good elasticity and improve the sealing effect.

[0105] Please refer to Figure 8 In another insulation method, an insulation element 61 can be provided between the heater 50 and the electrical control device 40 to configure it as an insulation structure 60.

[0106] The heat insulation element 61 can be made of a material with relatively low thermal conductivity to block heat transfer. The material of the heat insulation element 61 can be foam, rubber, phenolic foam board, aerogel, polystyrene foam, or extruded polystyrene board, etc., to provide good heat insulation performance. Furthermore, the heat insulation element 61 can be a plate-like structure or a membrane-like structure; this application does not limit the structural type of the heat insulation element 61. In addition, the heat insulation element 61 can be located at the communication port 13c on the cover 13, as described below, for connecting the second cavity 13a and the first cavity 11a. Alternatively, the heat insulation element 61 can directly separate the first cavity 11a and the second cavity 13a. Or, the heat insulation element 61 can be directly disposed within the first cavity 11a.

[0107] In this embodiment, the heat insulation structure 60 is formed by the heat insulation member 61, which makes it easy to form the heat insulation structure 60. This helps to improve the convenience of setting up the heat insulation structure 60 in order to achieve the function of heat insulation protection for the electronic control device 40.

[0108] Please refer to Figure 8 In one embodiment of this application, the shell cover 13 is provided with a communication port 13c, which is connected to the first cavity 11a and the second cavity 13a, and the heat insulation member 61 is covered by the communication port 13c.

[0109] The heat insulation member 61 covers the communication port 13c, including the case where the heat insulation member 61 is located inside the communication port 13c, and the case where the heat insulation member 61 is located outside the communication port 13c. It can be located on the outside of the end of the communication port 13c near the first cavity 11a, or it can be located on the outside of the end of the communication port 13c near the second cavity 13a.

[0110] In this embodiment, the connection port 13c simplifies the structure of the cover 13, thereby improving its ease of processing and molding. Covering the connection port 13c with the heat insulation component 61 minimizes the heat generated by the heater 50 in the second cavity 13a during operation from being transferred to the first cavity 11a, thus providing heat insulation protection for the electrical control device 40 located in the first cavity 11a. Furthermore, the connection port 13c also allows the wiring harness connecting the heater 50 and the electrical control device 40 to pass through, improving the convenience of wiring between them. In this case, a notch can be provided on the heat insulation component 61 to allow the wiring harness to pass through.

[0111] Additionally, it should be noted that when the first cavity 11a and the second cavity 13a, as described above, are simultaneously provided in the first housing 11, the connecting port 13c can also be provided in the first housing 11. Alternatively, when the first cavity 11a and the second cavity 13a are respectively provided in the first housing 11 and the cover 13, the connecting port 13c can be directly formed from the first opening 11a1 of the first cavity 11a.

[0112] Please refer to Figure 8 In one embodiment of this application, the compressor 100 further includes a first heat-conducting element 91, which covers the communication port 13c and is located at least on the side of the heat insulation element 61 facing away from the first housing 11.

[0113] The first heat-conducting element 91 can be made of a material with relatively high thermal conductivity to efficiently transfer heat. The material of the first heat-conducting element 91 can be metal, high thermal conductivity ceramic, or carbon fiber composite material, etc., to achieve good thermal conductivity. Furthermore, the first heat-conducting element 91 can be a plate-like structure or a film-like structure; this application does not limit the structural type of the first heat-conducting element 91. In addition, the first heat-conducting element 91 can be disposed within the connecting port 13c or outside the connecting port 13c, and can be located on the outer side of the connecting port 13c near the first cavity 11a or on the outer side of the connecting port 13c near the second cavity 13a. Furthermore, it is specified that the first heat-conducting element 91 can be disposed only on the side of the heat insulation member 61 facing away from the first housing 11, or it can be further disposed at other locations in addition to being disposed on the side of the heat insulation member 61 facing away from the first housing 11.

[0114] In this embodiment, by setting a first heat-conducting element, the heat generated by the heater 50 located in the second cavity 13a during operation can be efficiently transferred to the cover 13. The cover 13 is in contact with the outside air, thus exchanging heat with the outside air and quickly transferring the heat generated by the heater 50 to the outside air for heat dissipation, thereby reducing the temperature at the second cavity 13a. In other words, it can be said to reduce the temperature at the heat source. At the same time, combined with the heat insulation effect of the heat insulation component 61, the possibility of heat transfer to the first cavity 11a can be reduced as much as possible. In other words, it can be said to block the heat transfer path. Thus, by reducing the temperature at the heat source and blocking the heat transfer path, the impact of the heat generated by the heater 50 on the electronic control device 40 can be further reduced, improving the heat insulation protection effect of the electronic control device 40.

[0115] In one embodiment of this application, the first heat-conducting element 91 is welded or bonded to the shell cover 13.

[0116] In this embodiment, the first heat-conducting element 91 and the shell cover 13 are connected by welding or bonding. On the one hand, this can improve the sealing effect of the first heat-conducting element 91 on the connecting port 13c, reducing the impact of heat or moisture entering the first cavity 11a on the electronic control device 40. On the other hand, it can also make the connection between the first heat-conducting element 91 and the shell cover 13 simpler and more stable.

[0117] Please refer to Figure 8 In one embodiment of this application, to simplify the installation arrangement of the first heat-conducting element 91 and the heat-insulating element 61, the first heat-conducting element 91 is disposed on the outer side of the end of the connecting port 13c near the first cavity 11a and is attached to the shell cover 13. The heat-insulating element 61 is stacked on top of the first heat-conducting element 91. This allows the first heat-conducting element 91 and the heat-insulating element 61 to be installed on the outer side of the shell cover 13. Simultaneously, placing the heat-insulating element 61 on the outer side of the end of the connecting port 13c near the first cavity 11a also provides heat insulation for the correspondingly covered shell cover 13, thereby improving the heat insulation protection effect of the heat-insulating element 61 on the electronic control device 40.

[0118] In one embodiment of this application, the heat insulation member 61 and the first heat-conducting member 91 can be configured to be bonded together in order to improve the stability of the connection between the two and further simplify the connection of the heat insulation member 61.

[0119] Please refer to Figure 9 In one embodiment of this application, the compressor 100 further includes a second heat-conducting element 93, which is disposed between the connector 52 and the housing cover 13 and contacts the connector 52 and the housing cover 13.

[0120] The second heat-conducting component 93 can be made of a material with relatively high thermal conductivity to efficiently transfer heat. Specifically, the material of the second heat-conducting component 93 can be thermally conductive silicone grease, allowing it to be filled between the connector 52 and the housing 13, improving ease of installation. It can also have high thermal conductivity to efficiently transfer heat to the housing 13. Alternatively, the material of the second heat-conducting component 93 can be thermally conductive gel or thermally conductive pad, etc.

[0121] In this embodiment, a second heat-conducting element 93 is provided between the connector 52 and the cover 13, so that the heat generated by the heater 50 during operation can be efficiently transferred to the cover 13 through the second heat-conducting element 93. Heat dissipation is achieved through heat exchange between the cover 13 and the outside air, which can improve the heat dissipation effect at the heat source, i.e., the first cavity 11a, thereby reducing the impact of the heat at the first cavity 11a on the electronic control device 40.

[0122] Please refer to Figure 9In one embodiment of this application, the outer wall surface of the shell cover 13 is provided with heat dissipation fins 131, and at least a portion of the heat dissipation fins 131 is provided corresponding to the second heat conduction element 93.

[0123] At least a portion of the heat dissipation fins 131 are provided corresponding to the second heat conductor 93. That is, the heat dissipation fins 131 may be provided only on the outer side of the cover 13 at the position corresponding to the second heat conductor 93, or the heat dissipation fins 131 may be provided at other positions.

[0124] In this embodiment, the arrangement of heat dissipation fins 131 can increase the heat dissipation area between the shell cover 13 and the outside air, thereby improving the heat exchange effect between the shell cover 13 and the outside air, and further improving the heat dissipation effect at the heat source.

[0125] This application also proposes a thermal management system, which includes a compressor 100. The specific structure of the compressor 100 can be referred to the above embodiments. Since this thermal management system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The thermal management system also includes a circulation pipeline, which can be connected to the liquid flow channel 50a of the compressor 100 so that after the heat exchange medium is heated in the heating flow channel 511a in the liquid flow channel 50a, it can be transferred to the place that needs to be heated through the circulation pipeline. The place that needs to be heated includes, but is not limited to, the battery, the engine, or the seat.

[0126] This application also proposes a vehicle that includes a thermal management system. The specific structure of the thermal management system can be referred to the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
