[0079] In all examples shown and discussed herein, any specific value should be interpreted as merely illustrative, and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0080] It should be noted that like reference numerals and letters in the various figures indicate similar items, and thus, once an item is defined in one figure, it need not be discussed further in subsequent figures.

[0081] According to one embodiment of the present application, a shell structure 101 is provided. As shown in FIGS. 4-7, the shell structure 101 includes a shell body provided with a cavity adapted to accommodate an electrical element core, a flow channel formed in the shell body and located at a wall portion of the cavity, the flow channel being adapted to flow a heat exchange medium.

[0082] Specifically, the shell structure 101 is used to carry an electrical element, an electrical element core, etc. The electrical element can be, but is not limited to, a capacitor, a battery, a controller, a power module, etc. The electrical element core refers to an electrical element without a shell. For ease of illustration, the electrical element core is a capacitor core 6. The capacitor core 6 is processed into a columnar structure through a metalizing film winding, gold spraying, etc. In this example, since the electrical element core is not covered with a shell, the heat generated by the operation of the electrical element core can be quickly conducted to the shell structure 101, thereby effectively improving the heat dissipation effect of the electrical element core. The material of the shell structure 101 can be, but is not limited to, metal, ceramic, etc.

[0083] In some embodiments of the present application, the metal material includes aluminum, copper, stainless steel, copper alloy, aluminum alloy, carbon steel, etc. The flow channel is a passage formed in the shell structure 101. The flow channel 5 is adapted to flow a heat exchange medium.

[0084] The heat exchange medium can be, but is not limited to, water, heat-conducting oil, etc.; the heat exchange medium can also be a phase-change fluid, such as freon, ammonia, hydrofluoroalkene, etc. The flow channel passes through the wall portion of the cavity, and the wall portion can conduct the heat of the electrical element core to the heat exchange medium, and then conduct the heat to the outside of the shell structure 101 through the flow of the heat exchange medium.

[0085] The shell structure 101 can be provided with one cavity or multiple cavities. For example, 2, 3, 4, 5, etc. One cavity can be provided with one electrical element core or multiple electrical element cores.

[0086] In the embodiments of the present application, the shell body is provided with a cavity. The cavity is used to accommodate an electrical element core. Since the electrical element core is not covered with a shell, the heat generated by the operation of the electrical element core can be quickly conducted to the shell structure 101, and then conducted to the outside through the shell structure 101, thereby effectively improving the heat dissipation effect of the electrical module 1001. In addition, the shell structure 101 is provided with a flow channel located at a wall portion of the cavity. The heat of the electrical element core is first conducted to the wall portion of the cavity, and then conducted outward through the heat exchange medium in the flow channel 5. This arrangement further improves the heat dissipation effect of the shell structure 101.

[0087] In one example, the wall of the cavity includes a side wall 120 and a top wall, the side wall 120 is connected with the top wall, and the flow channel 5 is arranged in at least one of the side wall 120 and the top wall.

[0088] As shown in FIG. 1, FIG. 23, and FIG. 26, the shell body is provided with a first cavity 201 and a second cavity 202. The wall of the first cavity 201 and the second cavity 202 is connected with the base plate 1, and is located on one side of the base plate 1. The first cavity 201 and the second cavity 202 are cuboids, cylinders, or the like. For example, each cavity includes four side walls 120 connected with the base plate 1. A top wall is arranged opposite to the base plate 1. A top wall cover is arranged on the top of the four side walls 120. The flow channel 5 is arranged in the side wall 120 and the top wall. As shown in FIG. 7, the side walls 120 of the two cavities are arranged along the Z axis, and the flow channel 5 extending along the Z axis is arranged in the side wall 120. The top wall includes a flow channel wall 111 and a cover plate 110, and the flow channel 5 is formed between the flow channel wall 111 and the cover plate 110, which is in communication with the flow channel 5 arranged in the two side walls 120, which makes the processing of the flow channel 5 easy. The flow channel 5 communicating the two cavities is arranged on the base plate 1. As shown in FIG. 5, FIG. 6, and FIG. 8, the inlet 505 of the flow channel 5 of the shell structure 101 is located on the left side of the bottom of the base plate 1, and the outlet 501 is located on the right side of the bottom of the base plate 1. The middle part of the base plate 1 is provided with a flow channel wall 111 and a cover plate 110. The flow channel 5 communicating the first cavity 201 and the second cavity 202 is formed between the cover plate 110 and the flow channel wall 111. As shown in FIG. 2, the heat exchange medium enters the wall of the first cavity 201 through the inlet 505, then reaches the wall of the second cavity 202 through the flow channel 5 in the base plate 1, and then flows out through the outlet 501.

[0089] In another embodiment, as shown in FIGS. 23-27, the first cavity 201 and the second cavity 202 are cuboids. The outlet 501 and the inlet 505 are located on the left side of the X-axis of the substrate 1, and the outlet 501 and the inlet 505 are in communication with the flow channel 5 of the first cavity 201. The side wall 120 and the top wall of the first cavity 201 and the second cavity 202 are provided with the flow channel 5. The top wall includes the flow channel wall 111 and the cover plate 110. The cover plate 110 is mounted on the flow channel wall 111, and the flow channel 5 is formed between the two. For example, the flow channels 5 of the first cavity 201 for communicating with the outlet 501 and the inlet 505 are isolated from each other. The substrate 1 is provided with a flow channel 5 that communicates the first cavity 201 and the second cavity 202. The substrate 1 is provided with two flow channels 5 that are isolated from each other, one of which is used for liquid inlet of the second cavity 202, and the other of which is used for liquid outlet of the second cavity 202. The flow channels 5 of the side wall 120 and the top wall of the second cavity 202 are in communication. As shown in FIG. 28, the heat exchange medium enters the substrate 1 through the inlet 505, then flows through the side wall 120 and the top wall of the first cavity 201, then flows through the substrate 1 and the side wall 120 and the top wall of the second cavity 202, then reaches the substrate 1 again, and then reaches the first cavity 201 through the substrate 1, flows through the side wall 120 and the top wall of the first cavity 201 to the outlet 501 of the substrate 1, and flows out of the outlet 501.

[0090] In other examples, the flow channel 5 can also be provided only on the side wall 120 or the top wall of the first cavity 201 or the second cavity 202. The cross section of the flow channel 5 can be circular, rectangular, arc-shaped, triangular, etc.

[0091] In this example, the flow channel 5 covers the top wall and / or the side wall 120 of the cavity, which makes the heat dissipation effect of the shell structure 101 good.

[0092] In one example, the side wall 120 includes a first side wall and a second side wall arranged at intervals, and the top wall is connected to the same side of the first side wall and the second side wall. The flow channel 5 is arranged on and in the first side wall, the top wall, and the second side wall, and the flow channels 5 in the first side wall, the top wall, and the second side wall are in communication.

[0093] As shown in FIGS. 1, 7, 23, 26, 28, the first cavity 201 and the second cavity 202 are provided with flow channels 5 on the two side walls 120 and the top wall opposite to each other in the X-axis direction. The whole heat exchange medium flows in the X-axis direction. Since the flow channels 5 are provided on the first side wall, the top wall, and the second side wall, the path of the heat exchange medium flowing through the first cavity 201 and the second cavity 202 is significantly increased, so that the heat dissipation of the shell structure 101 is faster, and the heat generated by the electrical element core can be quickly conducted to the heat exchange medium and taken out of the shell structure 101 by the flow of the heat exchange medium. The heat dissipation effect of the shell structure 101 is good.

[0094] In other examples, the flow channels 5 can also be provided on all the side walls 120 and the top wall of the first cavity 201 and the second cavity 202, and the flow channels 5 of the same cavity can be connected to each other, so that the heat dissipation effect of the shell is excellent.

[0095] In one example, as described above, the shell body includes a base plate 1 which is spaced apart from the top wall, and the base plate 1 is connected to the side walls 120.

[0096] As shown in FIGS. 4, 6, 7, and 8, the base plate 1 has a rectangular structure as a whole, and the first cavity 201 and the second cavity 202 are arranged along the X-axis direction of the base plate 1. The base plate 1 and the top wall are spaced apart in the Z-axis direction. The base plate 1, the top wall, and the side walls 120 together enclose the first cavity 201 and the second cavity 202. The base plate 1 is formed by die casting or casting. Part of the side walls 120 and the top wall are integrally formed, for example, by die casting or casting. The base plate 1 and the side walls 120 are connected together by means of bolting, riveting, clamping, etc. The base plate 1, the top wall, and the side walls 120 can also be formed by carving and milling a whole plate. The base plate 1 is also provided with a connecting column. The connecting column is suitable for connecting with external equipment. For example, the connecting column is connected with the external equipment by means of bolting, bonding, clamping, riveting, welding, etc. The connecting column can also be used to set and carry other components.

[0097] In one example, the base plate 1 is provided with a first port and a second port, and the first port and the second port are both connected to the flow channel 5.

[0098] As described above, the first port is the inlet 505, and the second port is the outlet 501. The outlet 501 and the inlet 505 are respectively connected to the flow channel 5. For example, the base plate 1 is used to carry the side walls 120 and the top wall, and the inlet 505 and the outlet 501 are provided on the base plate 1. Compared with providing the first port and the second port on the side walls 120 and the top wall, the way of providing the first port and the second port on the base plate 1 makes the heat dissipation performance of the base plate 1 better. The base plate 1 is used to connect with external equipment, and providing the first port and the second port on the base plate 1 makes it easy for the flow channel 5 to be connected to the external equipment. For example, as shown in FIGS. 5 and 8, the inlet 505 and the outlet 501 are located on the bottom surface of the base plate 1 and are respectively located on the two sides of the X-axis direction of the base plate 1, and the heat exchange medium adopts the way of entering from one end and discharging from the other end. It can also be that, as shown in FIGS. 23 to 28, the inlet 505 and the outlet 501 are located on the same end of the X-axis direction of the base plate 1, which makes it easy for the inlet 505 and the outlet 501 to be connected to the external equipment, and the heat exchange medium is folded back at the second cavity 202, which makes the length of the flow channel 5 in the shell structure 101 longer. The heat dissipation effect of the shell structure 101 is better. Moreover, the heat dissipation of the whole shell body is more uniform.

[0099] In one example, the plurality of cavities are arranged in the housing body along a first direction.

[0100] As shown in FIG. 1, FIG. 7, FIG. 23, FIG. 26, and FIG. 28, two cavities are arranged at two ends of the X-axis direction of the substrate 1. An inlet 505 and an outlet 501 are arranged on the substrate 1. The flow channel 5 is connected to the two cavities. This arrangement makes the flow channel 5 pass through a larger range, and the heat is not concentrated on the substrate 1, and the heat dissipation effect of the housing structure 101 is better. In addition, the design of the flow channel 5 is more reasonable, and the connection of the flow channel 5 with external equipment becomes easy.

[0101] Of course, the number of cavities is not limited to the above-mentioned embodiment, and can also be 3, 4, 5, 6, etc. The plurality of cavities can be arranged in multiple rows.

[0102] In one example, the flow channel 5 of the wall of the plurality of cavities is connected, as described above.

[0103] In this example, as shown in FIG. 1, FIG. 7, FIG. 23, FIG. 26, and FIG. 28, the flow channels 5 of the top walls and side walls 120 of the two cavities are connected to each other, for example, through the flow channel 5 of the substrate 1. This arrangement enables the heat exchange medium to flow through multiple cavities at a time, thereby dissipating heat from multiple cavities, and the heat dissipation effect of each cavity is more excellent.

[0104] In one example, the plurality of cavities are arranged in the housing body along a first direction.

[0105] As shown in FIG. 1, FIG. 7, FIG. 23, FIG. 26, and FIG. 28, the first cavity 201 and the second cavity 202 are arranged along the X-axis direction of the substrate 1, i.e., along the long side of the substrate 1. The whole flow channel 5 extends along the long side. The space between the two cavities and / or the space on the upper surface of the two cavities can be used to accommodate devices such as power modules. In this way, the heat dissipation effect of each part of the housing structure 101 is more uniform, avoiding the problem of poor local heat dissipation effect of the housing body due to the arrangement of multiple cavities being too concentrated.

[0106] Of course, the first direction is not limited to the X-axis direction, but can also be other directions.

[0107] In one example, the housing structure 101 further comprises a positioning bracket adapted to accommodate the electrical element core, the positioning bracket being arranged in the cavity, and the electrical element core being isolated from the wall of the cavity by the positioning bracket.

[0108] As shown in FIG. 1 and FIG. 23, the capacitor core 6 is prone to damage when assembled into the cavity due to the absence of the shell. In addition, after the capacitor core 6 is installed into the cavity, the cavity needs to be filled with the sealant 30. The sealant 30 needs to wrap the capacitor core 6. The sealant 30 also serves as an insulator. Therefore, a gap needs to be formed between the inner wall of the cavity and the capacitor core 6. The gap prevents the inner wall from contacting the capacitor core 6, thereby achieving insulation. In this example, the shell structure 101 further comprises a positioning bracket. The positioning bracket is a frame structure capable of accommodating at least part of the capacitor core 6. The positioning bracket can define the position of the capacitor core 6 in the cavity, preventing the capacitor core 6 from moving in the cavity, thereby preventing the capacitor core 6 from conducting electricity by contacting the inner wall and preventing the capacitor core 6 from being damaged. The positioning bracket can also form a gap between the capacitor core 6 and the inner wall of the cavity, so that when the sealant 30 is injected, the sealant 30 can fill the gap, thereby effectively wrapping the capacitor core 6 and insulating the capacitor core 6 from the inner wall of the cavity.

[0109] The positioning bracket can both position the capacitor core 6 and bear the weight of the capacitor core 6, or the positioning bracket can only position the capacitor core 6 without bearing the weight of the capacitor core 6.

[0110] In some embodiments of the present application, the positioning bracket is made of insulating material, such as plastic, ceramic, glass, silica gel, rubber, etc. The insulating material can prevent the capacitor core 6 from conducting electricity through the positioning bracket and the shell structure 101, thereby preventing the capacitor core 6 from leaking electricity.

[0111] In one example, the positioning bracket comprises a base 153 and a positioning portion connected to the base 153, the positioning portion being arranged around the electrical element core, and the side of the positioning portion opposite to the base 153 forming a mounting opening.

[0112] As shown in FIG. 16 to FIG. 22, the base 153 is opposite to one mounting surface of the capacitor core 6. The base 153 can have a plate-like, ring-like, mesh-like structure, etc. The base 153 has a set thickness to separate the inner wall of the cavity from the mounting surface of the capacitor core 6. The positioning portion is arranged around the capacitor core 6.

The height of the main drive capacitor assembly 3 is less than or equal to the distance between the two opposite first positioning strips 151. The length of the main drive capacitor assembly 3 is less than or equal to the distance between the two second positioning strips 152. The length of the two first positioning strips 151 on the same long side is greater, so as to be able to bear the weight of the capacitor core 6 assembly. The length of the two second positioning strips 152 is smaller, so as to be able to play a role of positioning and isolating the main drive capacitor assembly 3.

[0116] As shown in FIGS. 16-19, the positioning bracket includes a second positioning bracket 16. The second positioning bracket 16 is used for positioning the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12. The second positioning bracket 16 includes two parts.

In other examples, the two positioning brackets used for positioning the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 can also be independently arranged without being integrated together.

[0117] Of course, the structures and the number of the base 153, the first positioning bars 151, and the second positioning bars 152 are not limited to the above-described examples.

This arrangement can effectively avoid the first positioning strip 151 and the second positioning strip 152 scratching any of the above-mentioned capacitor assemblies during the installation of the capacitor assemblies into the installation openings.

[0120] As shown in FIG. 21 and FIG. 22, the side edge of the base 153 away from the first positioning strip 151 is provided with a chamfer. The chamfer is round or bevel.

This makes the installation of the positioning bracket into the cavity easier.

[0121] In other examples, as shown in FIG. 23, FIG. 34 to FIG. 36, the first positioning bracket 15 includes the base 153 and a frame 154 surrounding the edge of the base 153.

The base 153 and the frame 154 are used to isolate the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 from the inner wall of the first cavity 201. In some embodiments of the present application, the end of the connecting arm 155 away from the base 153 is formed with a chamfer, which is round or bevel.

The base 153 of the second positioning bracket 16 can separate the inner wall of the second cavity 202 opposite to the opening from the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12.
