[0073] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0074] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0075] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0076] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0077] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0078] According to one embodiment of the present application, a housing structure is provided. Figures 4 to 7As shown, the shell structure includes: a shell body, the shell body is provided with a cavity, the cavity is suitable for accommodating an electrical component core, a flow channel is formed in the shell body, the flow channel is located at the wall of the cavity, and the flow channel is suitable for circulating a heat exchange medium.

[0079] Specifically, the shell structure is used to carry electrical components, electrical component cores, etc. The electrical components can be but are not limited to capacitors, batteries, controllers, power modules, etc. The electrical component core refers to the electrical component without the shell. For ease of explanation, the electrical component core is a capacitor core 6. The capacitor core 6 is processed into a columnar structure through processes such as winding and gold spraying of a metallized film. In this example, since the electrical component core is not covered with a shell, the heat generated by the electrical component core can be quickly conducted to the shell structure, thereby effectively improving the heat dissipation effect of the electrical component core. The material of the shell structure can be but is not limited to metal, ceramic, etc. Optionally, the metal material includes aluminum, copper, stainless steel, copper alloy, aluminum alloy, carbon steel, etc. The flow channel is a channel formed in the shell structure. The flow channel 5 is suitable for circulating heat exchange media.

[0080] The heat exchange medium may be, but is not limited to, water, thermal oil, etc.; the heat exchange medium may also be a phase change fluid, such as Freon, ammonia, hydrofluoroolefins, etc. The flow channel passes through the wall of the cavity, and the wall can transfer the heat of the core of the electrical component to the heat exchange medium, and then the heat is transferred to the outside of the shell structure through the flow of the heat exchange medium.

[0081] The housing structure may be provided with one cavity or multiple cavities, for example, 2, 3, 4, 5, etc. One electrical component core may be provided in one cavity, or multiple electrical component cores may be provided in one cavity.

[0082] In an embodiment of the present application, the shell body is provided with a cavity. The cavity is used to accommodate the core of the electrical component. Since the core of the electrical component is not covered with a shell, the heat generated by the operation of the core of the electrical component can be quickly conducted to the shell structure, and the heat is conducted to the outside via the shell structure, thereby effectively improving the heat dissipation effect of the electrical module. In addition, a flow channel is provided in the shell structure, and the flow channel is located on the wall of the cavity. The heat of the core of the electrical component is first conducted to the wall of the cavity, and then conducted to the outside via the heat exchange medium in the flow channel 5. This arrangement further improves the heat dissipation effect of the shell structure.

[0083] In one example, the wall portion of the cavity includes a side wall 120 and a top wall, the side wall 120 is connected to the top wall, and the flow channel 5 is disposed on at least one of the side wall 120 and the top wall.

[0084] like Figure 1 , Fig.23 , Fig.26As shown, the shell body is provided with a first cavity 201 and a second cavity 202. The walls of the first cavity 201 and the second cavity 202 are both connected to the substrate 1 and are both located on one side of the substrate 1. The first cavity 201 and the second cavity 202 are rectangular parallelepiped, cylindrical or other structures. For example, each cavity includes four side walls 120, and the four side walls 120 are connected to the substrate 1. The top wall is arranged opposite to the substrate 1. The top wall cover is arranged on the top of the four side walls 120. The flow channel 5 is arranged in the side walls 120 and the top wall. Figure 7 As shown, the side walls 120 of the two cavities are arranged along the Z axis, and a flow channel 5 extending along the Z axis is arranged in the side walls 120. The top wall includes a flow channel wall 111 and a cover plate 110, and a flow channel 5 is formed between the flow channel wall 111 and the cover plate 110. The flow channel 5 is connected to the flow channels 5 located in the two side walls 120. This arrangement makes it easy to process the flow channel 5. The flow channel 5 connecting the two cavities is arranged on the substrate 1. Figure 5 , Figure 6 , Figure 8 As shown, the inlet 505 of the flow channel 5 of the shell structure is located on the left side of the bottom of the substrate 1, and the outlet 501 is located on the right side of the bottom of the substrate 1. The middle part of the substrate 1 is provided with a flow channel wall 111 and a cover plate 110. The flow channel 5 connecting the first cavity 201 and the second cavity 202 is formed between the cover plate 110 and the flow channel wall 111. Figure 2 As shown, 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 substrate 1 , and then flows out through the outlet 501 .

[0085] In another embodiment, Figure 23 to Figure 27 As shown, the first cavity 201 and the second cavity 202 are both rectangular parallelepipeds. The outlet 501 and the inlet 505 are both located on the left side of the X-axis of the substrate 1, and the outlet 501 and the inlet 505 are both connected to the flow channel 5 of the first cavity 201. The side walls 120 and the top wall of the first cavity 201 and the second cavity 202 are provided with flow channels 5. The top wall includes a flow channel wall 111 and a cover plate 110. The cover plate 110 is mounted on the flow channel wall 111, and a 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 connecting the first cavity 201 and the second cavity 202. The substrate 1 is provided with two flow channels 5 isolated from each other, one of the two flow channels 5 is used for the liquid inlet of the second cavity 202, and the other is used for the liquid outlet of the second cavity 202. The side wall 120 of the second cavity 202 is connected to the flow channel 5 of the top wall. like Fig.28As shown, the heat exchange medium enters the substrate 1 from the inlet 505, then flows through the side walls 120 and the top wall of the first cavity 201, then flows through the substrate 1 and the side walls 120 and the top wall of the second cavity 202, reaches the substrate 1 again, then reaches the first cavity 201 through the substrate 1, flows through the side walls 120 and the top wall of the first cavity 201 to reach the outlet 501 of the substrate 1, and flows out from the outlet 501.

[0086] In other examples, the flow channel 5 may 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 may be circular, rectangular, arc-shaped, triangular, or the like.

[0087] In this example, the flow channel 5 covers the top wall and / or the side wall 120 of the cavity, which enables a good heat dissipation effect of the housing structure.

[0088] In one example, the side wall 120 includes a first side wall and a second side wall that are spaced apart, 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 the first side wall, the top wall and the second side wall, and the flow channels 5 located in the first side wall, the top wall and the second side wall are connected.

[0089] like Figure 1 , Figure 7 , Fig.23 , Fig.26 , Fig.28 As shown, 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 heat exchange medium flows along the X-axis direction as a whole. Since the flow channels 5 are provided on the first side wall, the top wall and the second side wall, the paths of the heat exchange medium flowing through the first cavity 201 and the second cavity 202 are significantly increased, so that the heat dissipation of the shell structure is faster, and the heat emitted by the core of the electrical component can be quickly conducted to the heat exchange medium and brought to the outside of the shell structure by the flow of the heat exchange medium. The heat dissipation effect of the shell structure is excellent.

[0090] In other examples, the flow channels 5 may 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 may be interconnected, so that the heat dissipation effect of the shell is excellent.

[0091] In one example, as mentioned above, the shell body includes a substrate 1 , the substrate 1 is spaced apart from the top wall, and the substrate 1 is connected to the side wall 120 .

[0092] like Figure 4 , Figure 6 , Figure 7 , Figure 8As shown, the substrate 1 is an overall rectangular structure, and the first cavity 201 and the second cavity 202 are arranged along the X-axis direction of the substrate 1. The substrate 1 and the top wall are spaced apart in the Z-axis direction. The substrate 1, the top wall and the side wall 120 together enclose the first cavity 201 and the second cavity 202. The substrate 1 is formed by die casting or casting. The side wall 120 and the top wall are partially formed in one piece, for example, by die casting or casting. The side wall 120 and the substrate 1 are connected together by bolt connection, riveting, clamping, etc. The substrate 1, the top wall and the side wall 120 can also be formed by whole plate engraving and milling. A connecting column is also provided on the substrate 1. The connecting column is suitable for connecting to an external device. For example, the connecting column is connected to an external device by bolt connection, bonding, clamping, riveting, welding, etc. The connecting column can also be used to set and carry other components.

[0093] In one example, a first opening and a second opening are provided on the substrate 1 , and both the first opening and the second opening are communicated with the flow channel 5 .

[0094] As mentioned above, the first opening is the inlet 505, and the second opening is the outlet 501. The outlet 501 and the inlet 505 are respectively connected to the flow channel 5. For example, the substrate 1 is used to support the side wall 120 and the top wall, and the inlet 505 and the outlet 501 are provided on the substrate 1. Compared with providing the first opening and the second opening on the side wall 120 and the top wall. The way of providing the first opening and the second opening on the substrate 1 makes the heat dissipation performance of the substrate 1 better. The substrate 1 is used for connection with external equipment, and providing the first opening and the second opening on the substrate 1 makes it easy to connect the flow channel 5 with the external equipment. For example, Figure 5 , Figure 8 As shown, the inlet 505 and the outlet 501 are located on the bottom surface of the substrate 1 and are located on both sides of the X-axis direction of the substrate 1, and the heat exchange medium adopts the method of liquid inlet at one end and liquid outlet at the other end. It can also be, as Figure 23 to Figure 28 As shown, the inlet 505 and the outlet 501 are located at the same end of the substrate 1 in the X-axis direction. This arrangement makes it easy to connect the inlet 505 and the outlet 501 with external equipment, and the heat exchange medium is turned back at the second cavity 202, which makes the length of the flow channel 5 in the shell structure longer. The heat dissipation effect of the shell structure is better. In addition, the heat dissipation of the shell body as a whole is more uniform.

[0095] In one example, a plurality of cavities are disposed in the shell body, and the flow channel 5 is located on the walls of the plurality of cavities.

[0096] like Figure 1 , Figure 7 , Fig.23 , Fig.26 , Fig.28As shown, the two cavities are respectively located at the two ends of the substrate 1 in the X-axis direction. The substrate 1 is provided with an inlet 505 and an outlet 501. The flow channel 5 connects the two cavities. This arrangement makes the flow channel 5 pass through a larger range, and heat concentration will not be formed on the substrate 1, and the heat dissipation effect of the shell structure is better. In addition, the design of the flow channel 5 is more reasonable, and the connection between the flow channel 5 and the external device becomes easy.

[0097] Of course, the number of cavities is not limited to the above embodiment, and may also be 3, 4, 5, 6, etc. The plurality of cavities may be arranged in a plurality of rows.

[0098] In one example, as mentioned above, the flow channels 5 of the walls of a plurality of the cavities are connected.

[0099] In this example, if Figure 1 , Figure 7 , Fig.23 , Fig.26 , Fig.28 As shown, the flow channels 5 of the top wall and the side wall 120 of the two cavities are interconnected, for example, through the flow channels 5 located on the substrate 1. This arrangement allows the heat exchange medium to flow through multiple cavities at one time, thereby dissipating heat for multiple cavities, and the heat dissipation effect of each cavity is better.

[0100] In one example, a plurality of the cavities are arranged in the housing body along a first direction.

[0101] like Figure 1 , Figure 7 , Fig.23 , Fig.26 , Fig.28 As shown, the first cavity 201 and the second cavity 202 are arranged along the X-axis direction of the substrate 1, that is, along the long side of the substrate 1. The entire flow channel 5 extends along the long side. The space between the two cavities and / or the space on the upper surfaces 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 shell structure is more uniform, avoiding the problem of poor local heat dissipation effect of the shell body due to the over-concentration of multiple cavities.

[0102] Of course, the first direction is not limited to the X-axis direction, but may also be other directions.

[0103] In one example, the housing structure further includes a positioning bracket, the positioning bracket is suitable for accommodating the electrical component core, the positioning bracket is disposed in the cavity, and the electrical component core is isolated from the wall of the cavity by the positioning bracket.

[0104] like Figure 1 , Fig.23As shown, since the capacitor core 6 is not provided with a shell, it is easy to collide when assembled into the cavity, resulting in damage to the capacitor core 6. In addition, after the capacitor core 6 is installed in the cavity, it is necessary to fill the cavity with sealant 30. The sealant 30 needs to wrap the capacitor core 6. The sealant 30 can also play an insulating role. 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 also includes a positioning bracket. The positioning bracket is a frame structure, and the positioning bracket can accommodate at least part of the capacitor core 6. The positioning bracket can limit the position of the capacitor core 6 in the cavity to prevent the capacitor core 6 from moving in the cavity, thereby preventing the capacitor core 6 from contacting the inner wall and conducting electricity, 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 poured, 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.

[0105] It is possible that the positioning bracket can both position the capacitor core 6 and bear the weight of the capacitor core 6 ; it is also possible that the positioning bracket does not bear the weight of the capacitor core 6 but is only used to position the capacitor core 6 .

[0106] Preferably, the positioning bracket is made of insulating material, such as plastic, ceramic, glass, silicone, rubber, etc. The insulating material can prevent the capacitor core 6 from being connected to the housing structure through the positioning bracket, thereby preventing the capacitor core 6 from leaking electricity.

[0107] In one example, the positioning bracket includes a base 153 and a positioning portion, the positioning portion is connected to the base 153 , the positioning portion is arranged around the electrical component core, and a mounting opening is formed on a side of the positioning portion opposite to the base 153 .

[0108] like Figures 16 to 22 As shown, the base 153 is opposite to a mounting surface of the capacitor core 6. The base 153 is a plate-shaped, ring-shaped, mesh-shaped structure, etc. The base 153 has a set thickness to separate the inner wall of the cavity and the mounting surface of the capacitor core 6. The positioning portion is arranged around the capacitor core 6. The positioning portion has a set thickness to separate the side of the capacitor core 6 connected to the mounting surface from the corresponding inner wall of the cavity. The positioning portion and the base 153 can bear the weight of the capacitor core 6, or they may not bear the weight of the capacitor core 6.

[0109] The base 153 and the positioning portion may be connected by welding, bonding, riveting, clamping, etc., or the base 153 and the positioning portion may be integrally formed by injection molding, stamping, casting, etc.

[0110] In one example, the positioning portion includes a plurality of positioning strips, and the plurality of positioning strips are arranged around the electrical component core.

[0111] like Figures 16 to 22 As shown, the cross section of the positioning strip is rectangular. The positioning strip is a strip-shaped sheet. The base 153 is rectangular in shape. A plurality of positioning strips are fixed on one side of the base 153. Figure 20 to Figure 22 As shown, the positioning bracket includes a first positioning bracket 15. The first positioning bracket 15 is used to position the main drive capacitor assembly 3 described below. Two first positioning bars 151 are respectively arranged on the two long sides of the base 153. The first positioning bars 151 of different long sides are arranged opposite to each other. A second positioning bar 152 is respectively arranged on the two short sides of the base 153. The two second positioning bars 152 are arranged opposite to each other. The length of the first positioning bar 151 is greater than the length of the second positioning bar 152. The four first positioning bars 151 and the two second positioning bars 152 surround the installation space. The ends of the four first positioning bars 151 away from the base 153 form an installation opening. The main drive capacitor assembly 3 is installed in the installation space through the installation opening. The main drive capacitor assembly 3 is installed in the first cavity 201. The height of the main drive capacitor assembly 3 is less than or equal to the distance between the two opposite first positioning bars 151. The length of the main drive capacitor assembly 3 is less than or equal to the distance between the two second positioning bars 152. The two first positioning bars 151 located on the same long side are relatively long, so they can bear the weight of the capacitor core 6 assembly. The two second positioning bars 152 are relatively short, so they can play a role in positioning and isolating the main driving capacitor assembly 3.

[0112] like Figures 16 to 19As shown, 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 described below. The second positioning bracket 16 includes two parts. The two parts are used to accommodate the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 respectively. The base 153 is rectangular as a whole. The base 153 includes two long sides and two short sides. The two long sides are arranged oppositely, and the two short sides are arranged oppositely. The two short sides are connected between the two long sides. A connecting arm 155 is connected to the middle of the two long sides. The connecting arm 155 divides the rectangle into two small rectangles. The two long sides of each small rectangle are respectively connected to two first positioning bars 151, and the first positioning bars 151 of different long sides are arranged oppositely in pairs. The two short sides are respectively connected to a second positioning bar 152. A second positioning bar 152 is arranged on the connecting arm 155, and the second positioning bar 152 divides the installation space surrounded by eight first positioning bars 151 and two second positioning bars 152 of the short sides into two sub-installation spaces. The two sub-installation spaces are used to accommodate the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12, respectively. In this example, the second positioning bracket 16 integrates the two positioning brackets used to position the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 together. The auxiliary drive capacitor assembly 9, the compressor capacitor assembly 12 and the positioning bracket are installed in the second cavity 202 together. The base 153, the first positioning bar 151 and the second positioning bar 152 of each sub-installation space separate the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 from the inner wall of the second cavity 202. The second positioning bar 152 located between the two sub-installation spaces separates the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12. The two first positioning bars 151 of the same long side of each sub-installation space can carry the corresponding auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12. In other examples, the two positioning brackets used to position the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 can also be independently set, without being integrated into one.

[0113] Of course, the structures and quantities of the base 153 , the first positioning strip 151 , and the second positioning strip 152 are not limited to the above-mentioned embodiments.

[0114] In one example, a chamfer is provided at one end of the positioning strip located at the installation opening, and the chamfer is suitable for avoiding the core of the electrical component.

[0115] like Fig.19 , Fig. 20As shown, a mounting opening is formed at one end of the first positioning bar 151 and the second positioning bar 152 away from the base 153. The mounting opening is used to mount the main drive capacitor assembly 3, the auxiliary drive capacitor assembly 9, and the compressor capacitor assembly 12. The first positioning bar 151 and the second positioning bar 152 are chamfered on the side facing the mounting space. For example, the chamfer is a rounded corner or an oblique angle. This arrangement can effectively prevent any of the above-mentioned capacitor assemblies from being scratched by the first positioning bar 151 and the second positioning bar 152 during the process of being installed into the mounting space through the mounting opening.

[0116] like Fig.21 , Fig. 22 As shown, a chamfer is provided at the edge of the side of the base 153 that is away from the first positioning strip 151. The chamfer is a rounded corner or an oblique corner. The chamfer can avoid the opening edge of the cavity, thereby avoiding the interference between the edge of the base 153 and the opening edge of the cavity during the process of installing the first positioning bracket 15 into the first cavity 201 and the process of installing the second positioning bracket 16 into the second cavity 202. This makes it easy to install the positioning bracket in the cavity.

[0117] In other examples, such as Fig.23 , Figure 34 to Figure 36 As shown, the first positioning bracket 15 includes a base 153 and a frame 154 arranged around the edge of the base 153. The base 153 and the frame 154 are fixed together by bonding, clamping, welding, etc. The main drive capacitor assembly 3 is clamped in the frame 154 and abuts against the base 153. The base 153 and the frame 154 are used to isolate the main drive capacitor assembly 3 from the inner wall of the first cavity 201.

[0118] like Figure 35 to Figure 37 As shown, the second positioning bracket 16 includes a base 153 and a frame 154 arranged around the edge of the base 153. The base 153 is a rectangular ring. A connecting arm 155 is arranged in the middle of the long side of the base 153. The base 153, the frame 154 and the connecting arm 155 are fixed together by bonding, clamping, welding and the like. The connecting arm 155 separates the base 153 into two parts. The two parts are used to position the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 respectively. The auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 are respectively clamped between the frame 154 and the connecting arm 155, and are against 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 respectively. Preferably, the end of the connecting arm 155 away from the base 153 forms a chamfer, and the chamfer is a rounded corner or an oblique angle. The chamfer makes it easy to install the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 on the second positioning bracket 16.

[0119] like Fig.39 , Fig.40As shown, a chamfer is provided on the side of the base 153 away from the frame 154. This makes it easy to install the second positioning bracket 16 in the cavity.

[0120] Of course, the structures of the first positioning bracket 15 and the second positioning bracket 16 are not limited to the above-mentioned embodiment.

[0121] In one example, the shell body is provided with an opening communicating with the cavity, and the mounting port is located at the opening.

[0122] like Figure 1 As shown, openings are provided on the side walls 120 of the first cavity 201 and the side walls 120 of the second cavity 202. The positioning brackets, the main drive capacitor assembly 3, the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 are installed in the corresponding cavities through the openings. The installation opening of the first positioning bracket 15 is located at the opening of the first cavity 201. The installation opening of the second positioning bracket 16 is located at the opening of the second cavity 202. The base 153 of the first positioning bracket 15 is located on the inner wall of the first cavity 201 opposite to the opening. The second positioning bracket 16 is located on the inner wall of the second cavity 202 opposite to the opening. In this way, the base 153 of the first positioning bracket 15 can separate the inner wall of the first cavity 201 opposite to the opening from the main drive capacitor assembly 3. 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.

[0123] In one example, a through hole is disposed in the middle of the base 153 .

[0124] like Fig.21 , Fig.38 As shown, a rectangular through hole is formed in the middle of the base 153. The through hole makes the heat dissipation effect of the main driving capacitor component 3 better. Fig.18 As shown, two rectangular through holes are formed in the middle of the base 153. The two through holes are respectively opposite to one surface of the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12, and the two through holes make the heat dissipation effect of the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 better.

[0125] In one example, a plurality of through holes are disposed in the middle of the base 153 , and isolation members are disposed between adjacent through holes.

[0126] like Fig.18 , Fig.35 As shown, two rectangular through holes are arranged in parallel in the middle of the base 153 of the second positioning bracket 16. An isolation member is arranged between the two through holes. The isolation member includes a connecting arm 155. The connecting arm 155 enhances the structural strength of the second positioning bracket 16.

[0127] Of course, the number of connecting arms 155 is not limited here, and can also be 2, 3, 4, 5, etc.

[0128] In one example, the shell body includes a substrate 1, the substrate 1 is spaced apart from the top wall, the substrate 1 is connected to the side wall 120, and the substrate 1, the side wall 120 or the top wall is provided with an opening communicating with the cavity.

[0129] like Figure 1 , Figure 2 , Figure 7 As shown, openings are provided on the side walls 120 of the first cavity 201 and the second cavity 202. The main drive capacitor assembly 3 is installed in the first cavity 201 along the Y-axis direction. The auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 are installed in the second cavity 202 along the Y-axis direction. The first positioning bar 151 located on one side of the substrate 1 can bear the weight of the main drive capacitor assembly 3, the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12.

[0130] like Figure 23 to Figure 26 As shown, two openings are provided on the substrate 1. The two openings are respectively connected to the first cavity 201 and the second cavity 202. The main drive capacitor assembly 3 is installed in the first cavity 201 along the Z-axis direction. The auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 are installed in the second cavity 202 along the Z-axis direction.

[0131] In this example, the provision of the opening facilitates the installation of the electrical component core in the cavity.

[0132] According to a second embodiment of the present application, an electrical module is provided, which includes the housing structure described in the present application and an electrical component core, wherein the electrical component core is located in the cavity.

[0133] like Figure 2 , Fig.24 As shown, a plurality of electrical component cores constitute an electrical component core assembly, for example, a main drive capacitor assembly 3, an auxiliary drive capacitor assembly 9 and a compressor capacitor assembly 12. The main drive capacitor assembly 3 is located in the first cavity 201. The auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12 are located in the second cavity 202.

[0134] In this example, since the electrical component core is not covered with a shell, the heat generated by the electrical component core can be quickly transferred to the shell structure, and then transferred to the outside through the shell structure. The heat dissipation effect of the electrical module is good.

[0135] In addition, a flow channel 5 is provided in the shell structure, and the flow channel 5 is located at the wall of the cavity. The heat of the electrical component core is first conducted to the wall of the cavity, and then conducted outward through the heat exchange medium in the flow channel 5. The flow channel 5 makes the heat dissipation effect of the electrical module better.

[0136] In one example, the electrical module further includes a bus bar, and the electrical component cores are multiple, and the multiple electrical component cores are connected to the bus bar.

[0137] like Figures 8 to 11 As shown, the busbar is used for conducting electricity. A plurality of welding port groups are arranged in an array on the busbar. Each welding port group is welded and connected to a capacitor core 6. The busbar connects the plurality of capacitor cores 6 together to form an electrical component core assembly. Multiple capacitors of the same electrical component core are connected in parallel. The electrical component core assembly is installed as a whole in the cavity. This makes it easy to install the electrical component core. For example, the electrical component core assembly includes the main drive capacitor assembly 3, the auxiliary drive capacitor assembly 9 and the compressor capacitor assembly 12.

[0138] In one example, the busbar includes a positive busbar and a negative busbar, and the plurality of electrical component cores are located between the positive busbar and the negative busbar.

[0139] like Fig. 9 , Fig.10 As shown, the positive bus and the negative bus are both rectangular structures.

In this arrangement, the positive bus and the negative bus can protect the capacitor core 6. The material of the positive bus and the negative bus is a metal plate. The metal plate is, for example, a copper alloy, an aluminum alloy, stainless steel, etc. For example, during installation, the electrical component core assembly (for example, the main drive capacitor assembly 3) is first installed in a positioning bracket (for example, a first positioning bracket 15), and then installed in a cavity (for example, a first cavity 201) with the positioning bracket (for example, the first positioning bracket 15). This arrangement makes it easy to install the electrical component assembly.
