[0018] The compression apparatus and thermal management integrated assembly of exemplary embodiments of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can complement or combine with each other.

[0019] According to a specific embodiment of the compression device and thermal management integrated assembly of this application, such as Figure 1 As shown, the thermal management integrated assembly includes a compression device 110 and a flow channel component 200, which are sealed together. The compression device 110 can compress a relatively low-temperature, low-pressure working medium into a relatively high-temperature, high-pressure working medium. The thermal management integrated assembly also includes a thermal management component 300, which can be a heat exchanger or other component, and is sealed together with the flow channel component 200. In a specific operating mode of the thermal management integrated assembly, the receiving cavity 11 of the compression device 110 and the receiving cavity 11 of the thermal management component 300 are connected, enabling the thermal management integrated assembly to perform functions such as heat exchange.

[0020] like Figures 2 to 4As shown, the compression device 110 includes a housing 1, an electrical connection assembly 2, and a compressor core 5. The housing 1 has a receiving cavity 11, and the compressor core 5 is located in the receiving cavity 11 of the housing 1. The receiving cavity 11 includes an oil chamber 111, and the housing 1 includes a first wall portion 12, which contacts the oil chamber 111. The oil chamber 111 is located on the side of the first wall portion 12 facing the compressor core 5. The compression device 110 has oil for lubrication, heat dissipation, etc., and the oil accumulates in the oil chamber 111. When the electrical connection assembly 2 is located in the first wall portion 12, the oil may seep into the location of the electrical connection assembly 2 and come into contact with it, which may easily lead to problems such as short circuits, poor contact, and failure of the electrical connection assembly 2, or even serious consequences such as sparks, combustion, and explosion. Especially when the compressor 110 is used in an air conditioner, the compressor 110 is used to compress the relatively low temperature and low pressure refrigerant into a relatively high temperature and high pressure refrigerant. The local temperature and pressure of the containment cavity 11 are high, and the refrigerant is usually flammable and explosive. The negative impact of the oil on the insulation of the electrical connection components 2 can easily lead to serious accidents.

[0021] like Figures 2 to 4 As shown, in this embodiment, the compression device 110 includes a protruding structure 3 connected to a first wall portion 12, extending from the first wall portion 12 toward the compressor core 5. The protruding structure 3 has a first hole 31, and the electrical connection assembly 2 is at least partially located in the first hole 31. When the electrical connection assembly 2 is located in the first wall portion, the protruding structure 3 can isolate the electrical connection assembly 2 from the oil in the oil chamber 111 of the housing 1 to a certain extent, thereby reducing the negative impact of the oil on the insulation of the electrical connection assembly 2, etc., and improving the safety of the compression device 110 and the thermal management integrated assembly.

[0022] In this embodiment, the first wall portion 12 is located at the lower end of the shell 1 along the direction of gravity, where the direction of gravity is... Figure 4 In the direction indicated by G, when the thermal management integrated component and / or compression device 110 is applied to a vehicle, the lower end of the housing 1 along the direction of gravity refers to the lower end of the housing 1 along the direction of gravity after the thermal management integrated component and / or compression device 110 is installed on the vehicle. When the thermal management integrated component and / or compression device 110 is applied to other scenarios, the lower end of the housing 1 along the direction of gravity refers to the lower end of the housing 1 along the direction of gravity when the thermal management integrated component and / or compression device 110 and other corresponding components are installed and can operate normally. It should be noted that when the thermal management integrated component and / or compression device 110 has different postures, as long as in any posture the protruding structure 3 of the compression device 110 is located at the lower end of the housing 1 along the direction of gravity, and the electrical connection component 2 is at least partially located in the first hole 31 of the protruding structure 3, so that the protruding structure 3 can isolate the electrical connection component 2 and the oil in the housing 1's receiving cavity 11 to a certain extent, the technical solutions and products thereof are all within the protection scope of this application.

[0023] like Figure 4 As shown, in this embodiment, the first hole 31 passes through the end of the protruding structure 3 facing away from the compressor core 5 and the end of the protruding structure 3 facing the compressor core 5. The first wall portion 12 includes a first end face 121, which is the end face of the first wall portion 12 facing the compressor core 5. The protruding structure 3 includes a second end face 32, which is the end face of the protruding structure 3 facing the compressor core 5. The distance between the first end face 121 and the second end face 32 is L, which is greater than or equal to 10 mm. When the compression device 110 is in different working states or a static state, the depth of the oil in the oil chamber 111 is usually less than 10 mm. A depth of L greater than or equal to 10 mm can improve the reliability of the oil in the oil chamber 111 of the protruding structure 3 in isolating the electrical connection assembly 2 and the housing 1, thereby reducing the negative impact of the oil on the electrical connection assembly 2.

[0024] like Figure 3 and Figure 6As shown, in this embodiment, the compression device 110 includes a compressor component 4, which is located in the receiving cavity 11. The compressor component 4 can be a compression mechanism (e.g., a stationary scroll and a moving scroll), a drive mechanism (e.g., a motor), an oil pump, or other components. That is, the compressor component 4 can include at least a portion of the compressor core 5, or other components of the compressor core 5. The housing 1 includes a second wall portion 13, which surrounds the periphery of the compressor component 4. The second wall portion 13 has a cylindrical structure, and the axis of the compressor component 4 and the axis of the second wall portion 13 are substantially coincident. The cylindrical structure of the second wall portion 13 is structurally compatible with the compressor component 4 and is simple and easy to manufacture. The axis of the second wall portion 13 is parallel to the flow channel of the flow channel component 200, and the second wall portion 13 and the flow channel component 200 are integrally extruded. The compression device 110 is vertically installed, that is, the axis of the second wall portion 13 extends along the direction of gravity, and the first wall portion 12 is located at the lower end of the second wall portion 13 in the axial direction and is sealed to the second wall portion 13. The electrical connection assembly 2 includes an electrical connector 21, which is an elongated strip structure. The electrical connector 21 is electrically connected to the compressor component 4. A first plane 101 is defined, and the axes of the first plane 101 and the second wall portion 13 are perpendicular. The projection of the electrical connector 21 onto the first plane 101 is the first projection, the projection of the compressor component 4 onto the first plane 101 is the second projection, and the projection of the second wall portion 13 onto the first plane 101 is the third projection. The first projection is located between the second and third projections. The electrical connector 21 has a larger axial dimension along the second wall portion 13 and a smaller radial dimension along the first wall portion 12. This structure can reduce the axial dimension of the compression device 110 along the second wall portion 13 and improve the space utilization of the housing 1's cavity 11. The number of electrical connectors 21 is at least two, and the at least two electrical connectors 21 are arranged in a line. The arrangement direction of the at least two electrical connectors 21 is perpendicular to the radial dimension of the first wall portion 12. This structure can reduce the radial dimension of the compression device 110 along the first wall portion 12 and further improve the space utilization of the housing 1's cavity 11.

[0025] like Figure 7As shown, in a first alternative embodiment of the electrical connector 21, the number of electrical connectors 21 is at least three. The electrical connectors 21 include a first electrical connector 211, a second electrical connector 212, and a third electrical connector 213. The projection of the first electrical connector 211 onto the first plane 101 is a first first projection; the projection of the second electrical connector 212 onto the first plane 101 is a second first projection; and the projection of the third electrical connector 213 onto the first plane 101 is a third first projection. It is understood that the shapes of the first, second, and third first projections are all identical to each other. The first first projection has a first point 2111, the second first projection has a second point 2121, and the third first projection has a third point 2131. The positions of the first point 2111 on the first first projection, the second point 2121 on the second first projection, and the third point 2131 on the third first projection are all identical to each other. The second projection has a fourth point 41, a fifth point 42, and a sixth point 43, which are located at the end of the second projection facing the first projection. The fourth point 41 is located on the second projection near the first point 2111, the fifth point 42 is located on the second projection near the second point 2121, and the sixth point 43 is located on the second projection near the third point 2131. Specifically, the straight line connecting the first point 2111 and the fourth point 41 extends radially along the first wall portion 12, the straight line connecting the second point 2121 and the fifth point 42 extends radially along the first wall portion 12, and the straight line connecting the third point 2131 and the sixth point 43 extends radially along the first wall portion 12. The arc connecting the first point 2111, the second point 2121 and the third point 2131 is parallel to the arc connecting the fourth point 41, the fifth point 42 and the sixth point 43. This structure allows the arrangement of the electrical connector 21 to be adapted to the structure of the compressor component 4, which can reduce the radial dimension of the compression device 110 along the first wall portion 12, and also facilitates the arrangement of the electrical connector 21.

[0026] like Figure 7As shown, in a second alternative embodiment of the electrical connector 21, the third projection has a seventh point 131, an eighth point 132, and a ninth point 133, all located at the end of the third projection facing the first projection. The seventh point 131 is located near the first point 2111 on the third projection, the eighth point 132 is located near the second point 2121 on the third projection, and the ninth point 133 is located near the third point 2131 on the third projection. Specifically, the straight line connecting the first point 2111 and the seventh point 131 extends radially along the first wall portion 12, the straight line connecting the second point 2121 and the eighth point 132 extends radially along the first wall portion 12, and the straight line connecting the third point 2131 and the ninth point 133 extends radially along the first wall portion 12. The arc connecting the first point 2111, the second point 2121 and the third point 2131 is parallel to the arc connecting the seventh point 131, the eighth point 132 and the ninth point 133. This structure adapts the arrangement of the electrical connector 21 and the structure of the second wall portion 13, which can reduce the radial dimension of the compression device 110 along the first wall portion 12, and at the same time make the second wall portion 13 smoother and flatter, which can reduce the risk of interference between the second wall portion 13 and other components, thereby facilitating the arrangement and assembly of the compression device 110.

[0027] like Figure 7 As shown, in a third alternative embodiment of the electrical connector 21, the arcs connecting the first point 2111, the second point 2121, and the third point 2131, the arcs connecting the fourth point 41, the fifth point 42, and the sixth point 43, and the arcs connecting the seventh point 131, the eighth point 132, and the ninth point 133 are all parallel to each other, so that the arrangement structure of the electrical connector 21 is adapted to the structure of the compressor component 4, and the arrangement structure of the electrical connector 21 is adapted to the structure of the second wall portion 13, thereby further reducing the radial dimension of the compression device 110 along the first wall portion 12, and further facilitating the arrangement and assembly of the compression device 110.

[0028] It should be noted that the first wall portion 12 is the lower end of the housing 1 along the direction of gravity. The first wall portion 12 can be a single wall or at least a portion of a single wall, or a combination of at least a portion of a single wall and at least a portion of other single walls. For example, when the compression device 110 is vertically installed, i.e., the axis of the second wall portion 13 extends along the direction of gravity, the first wall portion 12 can be located at the lower end of the housing 1 along the axial direction; when the compression device 110 is horizontally installed, i.e., the extension direction of the axis of the second wall portion 13 is perpendicular to the direction of gravity, the first wall portion 12 can be the lower end of the second wall portion 13 along the direction of gravity; when the compression device 110 is inclined, i.e., the angle between the extension direction of the axis of the second wall portion 13 and the direction of gravity is an acute angle or an obtuse angle, the first wall portion 12 can be a combination of at least a portion of the lower end of the housing 1 along the axial direction and at least a portion of the lower end of the second wall portion 13 along the direction of gravity.

[0029] like Figure 3 and Figure 4 As shown, in this embodiment, the protruding structure 3 and the first wall portion 12 are an integral structure. The first wall portion 12 is made of aluminum or aluminum alloy, and the protruding structure 3 is also made of aluminum or aluminum alloy. The first wall portion 12 is formed by extrusion of sheet metal, and the protruding structure 3 is formed by machining. The electrical connection assembly 2 includes a first fixing member 22 and a second fixing member 23. The first fixing member 22 is made of steel, and the second fixing member 23 is made of steel. The first fixing member 22 is welded to the protruding structure 3, and the second fixing member 23 is welded to the first fixing member 22. The first fixing member 22 includes a first connecting surface 221, and the protruding structure 3 includes a second connecting surface 33. The second connecting surface 33 is located on the protruding structure 3 near the first fixing member 22, and the first connecting surface 221 is located on the first fixing member 22 near the second connecting surface 33. The first connecting surface 221 and the second connecting surface 33 are brazed together. Optionally, the second connecting surface 33 can be the surface surrounding the first hole 31 of the protruding structure 3, the end face of the protruding structure 3 facing the compressor core 5, or the side face of the protruding structure 3 away from the first hole 31. Furthermore, the second connecting surface 33 can be a combination of at least a portion of each of the above-mentioned end faces. The first fixing member 22 includes a third connecting surface 222, and the second fixing member 23 includes a fourth connecting surface 231. The third connecting surface 222 is located on the first fixing member 22 near the second fixing member 23, and the fourth connecting surface 231 is located on the second fixing member 23 near the third connecting surface 222. The third connecting surface 222 and the fourth connecting surface 231 are formed by resistance welding.

[0030] like Figure 3 and Figure 4As shown, the second fixing member 23 has a second hole 232, through which the electrical connector 21 passes. The electrical connection assembly 2 includes an insulating member 24, which is fixed to the electrical connector 21 and the second fixing member 23. The insulating member 24 isolates the electrical connector 21 and the second fixing member 23. The insulating member 24 can be a glass sintered body to provide electrical insulation between the electrical connector 21 and the second fixing member 23. Since brazing can easily damage the insulating member 24, and the reliability of direct resistance welding between steel parts and aluminum and aluminum alloy parts is poor, the first fixing member 22 plays a transitional role. During the assembly of the compression device 110, the first fixing member 22 and the protruding structure 3 are first brazed, and then the assembled component consisting of the electrical connector 21, the insulating member 24, and the second fixing member 23 is resistance welded to the first fixing member 22 to ensure the reliability of the connection between the electrical connection assembly 2 and the protruding structure 3.

[0031] like Figure 3 and Figure 4 As shown, in this embodiment, a second plane 102 is defined, and the axes of the second plane 102 and the second wall portion 13 are parallel or coincident. The electrical connector 21 includes a first portion 214, which is the portion of the electrical connector 21 located on the second fixing member 23 away from the compressor core 5. The projection of the protruding structure 3 on the second plane 102 covers the projection of the first portion 214 on the second plane 102. This structure allows the protruding structure 3 to protect the electrical connector 21, while also making the outer contour of the housing 1 relatively flat, reducing the risk of interference between the compression device 110 and other components.

[0032] In this application, a protruding structure 3 extends from the first wall portion 12 toward the compressor core 5. The protruding structure 3 has a first hole 31, the extension direction of which is the same as the extension direction of the protruding structure 3, and the electrical connection assembly 2 is at least partially located in the first hole 31. When the electrical connection assembly 2 is located in the first wall portion, the protruding structure 3 can isolate the electrical connection assembly 2 from the oil in the oil chamber 111 of the housing 1 to a certain extent, thereby reducing the negative impact of the oil on the insulation of the electrical connection assembly 2, etc., and improving the safety of the compression device 110 and the thermal management integrated assembly.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the content of the technical solution of this application shall still fall within the scope of the technical solution of this application.
