[0002] With the rapid development of charging and distribution technology, charging and distribution equipment has been widely used in the automotive field. At present, as electric power conversion equipment, charging and distribution equipment is more sensitive to heat dissipation requirements, especially for vehicle charging and distribution equipment. The choice of heat dissipation method is usually related to the spatial conditions of the vehicle layout and the charging and distribution power.

[0003] In the related art, for models without water cooling systems such as water pumps and waterways, charging and distribution equipment with air cooling and heat dissipation functions are usually selected. At present, air cooling and heat dissipation usually arranges the fan under the charging and distribution equipment shell, and heat dissipation teeth are arranged under the shell. The fan sucks air and blows air to the surrounding heat dissipation teeth and the shell above to achieve the purpose of heat dissipation. However, the arrangement of the heat dissipation teeth causes the charging and distribution equipment to occupy a large space and is relatively bulky, making it difficult to arrange on a vehicle with a narrow space. Summary of the invention

[0004] The present application provides a shell assembly for a charging and distribution device, which not only meets the heat dissipation requirements of the charging and distribution device, but also reduces the space occupied by the shell assembly. There is no need to set up structures such as heat dissipation teeth, so that the charging and distribution device as a whole is relatively small and compact, which facilitates the arrangement of the charging and distribution device on electrical equipment with narrow space.

[0005] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, an embodiment of the present application provides a housing assembly for a charging and distribution device, comprising:

[0007] The shell body is formed with a receiving cavity with one end open, the receiving cavity is used to accommodate the charging and distribution module, and the outer surface of the shell body is provided with an air cooling groove;

[0008] The air cooling module is arranged on the outer side wall of the shell body, and at least part of the air outlet of the air cooling module is arranged opposite to the air cooling groove, so that the air cooling module is suitable for blowing air to the air cooling groove.

[0009] The shell assembly proposed in the first aspect of the present application is a shell assembly of the charging and distribution equipment, in which the air cooling module is arranged on the outer side wall of the shell body, and at the same time, an air cooling groove is directly arranged on the outer surface of the shell body, so that at least part of the air cooling module is arranged opposite to the air cooling groove, and the air cooling module is used to blow air into the air cooling groove to achieve heat dissipation and cooling of the charging and distribution module in the shell body. In this way, the heat dissipation requirements of the charging and distribution equipment are met, and the space occupied by the shell assembly is reduced. There is no need to set structures such as heat dissipation teeth, so that the charging and distribution equipment is relatively small and compact as a whole, which is convenient for the charging and distribution equipment to be arranged on electrical equipment with narrow space.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0053] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0054] It should be noted that with the rapid development of charging and distribution technology, charging and distribution equipment has been widely used in the automotive field. Currently, as electric power conversion equipment, charging and distribution equipment is more sensitive to heat dissipation requirements, especially for vehicle charging and distribution equipment. The choice of heat dissipation method is usually related to the spatial conditions of the vehicle layout and the charging and distribution power.

[0055] In the related technology, for vehicles without water pumps, water channels and other vehicle water cooling systems, charging and distribution equipment with air cooling and heat dissipation functions are usually selected, such as Figure 1 and Figure 2 As shown, the air-cooled heat dissipation of the conventional charging and distribution equipment 2000 usually sets the fan below the housing of the charging and distribution equipment, and the heat dissipation teeth 300 are arranged below the housing. The fan sucks air and blows air to the surrounding heat dissipation teeth 300 and the housing above to achieve the purpose of heat dissipation. However, the arrangement of the heat dissipation teeth causes the charging and distribution equipment to occupy a large space and is relatively bulky, making it difficult to arrange on a vehicle with a narrow space.

[0056] Based on this, the present application proposes a shell assembly 100 for a charging and distributing device 1000, in which the shell assembly 100 of the charging and distributing device 1000 sets the air cooling module 2 on the outer wall of the shell body 1, and at the same time, directly sets the air cooling groove 12 on the outer surface of the shell body 1, so that at least part of the air cooling module 2 is arranged opposite to the air cooling groove 12, and the air cooling module 2 is suitable for blowing air to the air cooling groove 12 to achieve heat dissipation and cooling of the charging and distributing module in the shell body 1. In this way, the heat dissipation requirements of the charging and distributing device 1000 are met, and the space occupied by the shell assembly 100 is reduced. There is no need to set structures such as heat dissipation teeth, so that the charging and distributing device 1000 is relatively small and compact as a whole, which is convenient for the charging and distributing device 1000 to be arranged on electrical equipment with narrow space.

[0057] It should be noted that if Figure 3-Figure 7 As shown, the present application is illustrated by taking the application of the housing assembly 100 to the charging and distribution equipment 1000 as an example, wherein the charging and distribution equipment 1000 can be used for vehicles, and can also be used for other electrical equipment that requires the use of the charging and distribution equipment 1000. The present application is only illustrated by taking the application of the charging and distribution equipment 1000 to vehicles.

[0058] The following describes a housing assembly 100 for a charging and distributing device 1000 , a charging and distributing device 1000 , and an electric device according to an embodiment of the present application with reference to the accompanying drawings.

[0059] like Figure 3-Figure 7 As shown, the housing assembly 100 according to the first embodiment of the present application includes: a housing body 1 and an air cooling module 2.

[0060] Among them, the shell body 1 forms a accommodating cavity 11 with an open end, the accommodating cavity 11 is used to accommodate the charging and distribution module, the outer surface of the shell body 1 is provided with an air cooling groove 12, the air cooling module 2 is arranged on the outer side wall of the shell body 1, and at least part of the air outlet of the air cooling module 2 is arranged opposite to the air cooling groove 12, so that the air cooling module 2 is suitable for blowing air to the air cooling groove 12.

[0061] Specifically, Figure 6 As shown, the shell body 1 includes a side wall and a bottom wall, and the side wall and the bottom wall are fixedly connected to jointly define a accommodating cavity 11 with one end open. Specifically, one end of the shell body 1 is an open end, and the other end (bottom wall) is a closed end. The open end of the shell body 1 is opposite to and spaced from the closed end. It can be understood that the open end of the shell body 1 is formed with a mounting port, and the mounting port is connected to the accommodating cavity 11. With this arrangement, the charging and distribution module can be fixedly installed in the accommodating cavity 11 through the mounting port.

[0062] It should be noted that the vehicle's charging and distribution module includes an on-board charger, a DCDC converter, a distribution box 200, etc., wherein the on-board charger is used to convert the AC power of the power grid into high-voltage DC power through power conversion to charge the power battery, the DCDC converter is used to convert high-voltage DC power into low-voltage DC power to power the low-voltage electrical appliances of the whole vehicle, and the distribution box 200 is used to distribute power to the high-voltage electrical appliances of the whole vehicle. As an electric power conversion module, the charging and distribution module will generate a lot of heat during the power conversion process, so it is necessary to dissipate the heat of the charging and distribution module in time.

[0063] Based on this, in some embodiments of this application, continue to refer to Figure 3 As shown, an air cooling groove 12 is provided on the outer surface of the shell body 1, and an air cooling module 2 is provided on the outer side wall of the shell body 1, wherein an air outlet of the air cooling module 2 is at least partially arranged opposite to the air cooling groove 12. For example, the air cooling groove 12 can be constructed as a recessed groove recessed inwardly toward the shell body 1, and the air cooling module 2 blows cold air toward the air outlet, and at least a part of the air outlet is arranged opposite to the air cooling groove 12, thereby ensuring that the air cooling module 2 blows cooling air toward the air cooling groove 12, so that the cooling air flows along the air cooling groove 12. With such a configuration, air cooling and heat dissipation of the charging and distribution module in the shell body 1 is realized, and the heat dissipation requirements of the charging and distribution equipment 1000 are met.

[0064] It can be understood that, compared with the traditional air cooling and heat dissipation of the charging and distribution equipment 1000, the air cooling groove 12 utilizes the shell body 1 as a cooling structure, and there is no need to set structures such as heat dissipation teeth, and the air cooling module 2 is set on the outer wall of the shell body 1, which greatly reduces the space occupied by the shell assembly 100, making the charging and distribution equipment 1000 as a whole relatively small and compact, which is convenient for the charging and distribution equipment 1000 to be arranged on electrical equipment with narrow space.

[0065] In some embodiments of the present application, the shell body 1 can be made of metal material or plastic material.

[0066] In some embodiments of the present application, the shell body 1 can be constructed as an integrally formed part, including but not limited to integral injection molding, integral stamping molding, integral casting molding, etc.

[0067] In summary, according to the shell assembly 100 proposed in the embodiment of the first aspect of the present application, the shell assembly 100 of the charging and distribution equipment 1000 sets the air cooling module 2 on the outer wall of the shell body 1, and at the same time, directly sets the air cooling groove 12 on the outer surface of the shell body 1, so that at least part of the air cooling module 2 is arranged opposite to the air cooling groove 12, and the air cooling module 2 is suitable for blowing air to the air cooling groove 12 to achieve heat dissipation and cooling of the charging and distribution module in the shell body 1. In this way, the heat dissipation requirements of the charging and distribution equipment 1000 are met, and the space occupied by the shell assembly 100 is reduced. There is no need to set structures such as heat dissipation teeth, so that the charging and distribution equipment 1000 is relatively small and compact as a whole, which is convenient for the charging and distribution equipment 1000 to be arranged on electrical equipment with narrow space.

[0068] In some embodiments of the present application, Figure 3 As shown, the charging and distribution module is fixedly arranged on the inner side of the bottom wall of the shell body 1, the air cooling groove 12 is arranged on the outer side of the bottom wall of the shell body 1, and at least part of the air outlet is arranged opposite to the extension direction of the air cooling groove 12, wherein the bottom wall of the shell body 1 is arranged opposite to the open end of the shell body 1.

[0069] Specifically, the charging and distribution module is arranged in the accommodating cavity 11 and is fixedly connected to the inner side of the bottom wall of the shell body 1. With this arrangement, the heat generated by the charging and distribution module is directly transferred to the bottom wall of the shell body 1. Based on this, in some embodiments of the present application, an air cooling groove 12 is correspondingly provided on the outer side of the bottom wall of the shell body 1. Optionally, the position of the air cooling groove 12 corresponds to the heat dissipation area of ​​the charging and distribution module. Furthermore, at least a portion of the air outlet of the air cooling module 2 on the side wall of the shell body 1 is arranged relative to the extension direction of the air cooling groove 12. For example, the cold air groove as a whole Extending from left to right along the bottom wall of the shell body 1, the air cooling module 2 can be arranged on the left side wall or the right side wall of the shell body 1, and the air outlet of the air cooling module 2 is at least partially arranged opposite to the extension direction of the cold air groove. Such an arrangement facilitates the cooling air blown out by the air cooling module 2 to directly enter the air cooling groove 12, and the air cooling groove 12 is arranged on the bottom wall of the shell body 1. When the cooling air flows along the air cooling groove 12, it is easier to bring out the heat generated by the charging and distribution module arranged on the inner side of the bottom wall of the shell body 1, thereby greatly improving the heat exchange efficiency and being beneficial to improving the air cooling and heat dissipation effect.

[0070] In some embodiments of the present application, Figure 5 and Figure 6As shown, a partition is provided in the accommodating cavity 11, and the accommodating cavity 11 is divided into a plurality of sub-accommodating cavity groups 14 by the partition. The plurality of sub-accommodating cavity groups 14 are arranged at intervals along the first direction X of the shell body 1, and each sub-accommodating cavity group 14 includes at least one sub-accommodating cavity, each sub-accommodating cavity extends along the second direction Y of the shell body 1, and each sub-accommodating cavity is used to accommodate at least one charging and distributing electronic module in the charging and distributing electrical module, wherein the first direction X is perpendicular to the second direction Y.

[0071] It should be noted that, at present, when the charging and distribution power is the same, the charging and distribution equipment 1000 will adopt different charging and distribution design solutions and heat dissipation methods due to different vehicle models, environments, vehicle layout and other factors, which will lead to the need to re-select components, PCB board routing and hardware circuit design. The current air cooling solution and water cooling solution of the charging and distribution equipment 1000 are both matched custom designs. With the rapid development of new energy vehicles, the iteration speed of vehicle models of various car companies is getting faster and faster, and the requirements for parts platformization are also getting higher and higher. If the charging and distribution equipment 1000 needs to develop new design types every time to match the cooling needs of different models, it will undoubtedly increase development costs and increase the verification cycle, which will seriously affect the iteration speed of the vehicle model. At the same time, it will also affect the production and stocking cycle, management costs, operating costs and stagnant material inventory costs of vehicle companies.

[0072] Based on this, the air cooling design scheme in this application draws on the design of the accommodating cavity 11 of the water cooling scheme, takes the water cooling scheme design as the starting point, and adopts a three-dimensional loop heat dissipation structure as a whole. Specifically, Figure 5 and Figure 6 As shown, referring to the water cooling scheme design, the accommodating chamber 11 is divided into a plurality of sub-accommodating chamber groups 14 by dividing parts. For example, the number of sub-accommodating chamber groups 14 can be 2, 3, 4, or 5, which is specifically set according to actual conditions and is not specifically limited here. Among them, multiple sub-cavity groups 14 are arranged at intervals along the first direction X of the shell body 1. It can be understood that each sub-cavity group 14 is a row, and multiple sub-cavity groups 14 are divided into multiple rows along the first direction X, and each sub-cavity group 14 includes at least one sub-cavity, and each sub-cavity extends along the second direction Y of the shell body 1. That is to say, the sub-cavities in each row of sub-cavity groups 14 extend along the second direction Y of the shell body 1. This arrangement makes the division of the sub-cavities more regular, and when a water-cooling design is required, the cavity 11 division scheme in the present application can be directly used for the shell body 1 with a water-cooling design, so that the cooling water channel in the shell body 1 surrounds the sub-cavity, thereby realizing the compatible design of the cavity 11 of the charging and distribution equipment 1000, reducing the cost of charging and distribution device division and wiring design, and reducing the pressure of research and development verification.

[0073] Furthermore, each sub-accommodation cavity is used to accommodate at least one charging and distribution electronic module in the charging and distribution module. It can be understood that the charging and distribution module in the present application includes an AC input filter module, a PFC busbar capacitor module, an AC input safety and terminal installation module, an OBC front-stage switch tube module, an OBC magnetic device module, a DCDC magnetic device module, an OBC rear-stage and DCDC switch tube module, an HV DC output filter module, a DCDC output filter module, and an interface communication and auxiliary source module. For example, Figure 5 and Figure 6 As shown, the accommodating chamber 11 in the present application is divided into three sub-accommodating chamber groups 14, and the three sub-accommodating chamber groups 14 are respectively formed with five sub-accommodating chambers, namely the first sub-accommodating chamber 141, the second sub-accommodating chamber 142, the third sub-accommodating chamber 143, the fourth sub-accommodating chamber 144, and the fifth sub-accommodating chamber 145, wherein the AC input filter module and the PFC busbar capacitor module in the present application are arranged in the fifth sub-accommodating chamber 145, the OBC magnetic device module and the DCDC magnetic device module are arranged in the third sub-accommodating chamber 143, and the HV DC output filter module and the DCDC output filter module are arranged in the first sub-accommodating chamber 141. In this way, the optimal partitioning is achieved according to different functional modules. Figure 2 , Figure 5 and Figure 6 As shown, compared with the flat layout of each charging and distribution electronic module in the traditional charging and distribution equipment 1000, and the separate partitioning of each small module, the present application adopts the idea of ​​large module partitioning to achieve a flexible partitioning effect, and can also support the flexible layout of small changes in iterative modified products, and realize the flexible standard design of secondary power devices.

[0074] In some embodiments of the present application, Figure 3 As shown, the air cooling groove 12 extends along the second direction Y. That is to say, the extension direction of the air cooling groove 12 on the bottom wall of the shell body 1 is consistent with the extension direction of the sub-accommodation cavity. Optionally, the air cooling groove 12 can be arranged between two adjacent different sub-accommodation cavities, or can be correspondingly arranged below the sub-accommodation cavity. In this way, when each charging and distributing electronic module of the charging and distributing electric module is installed in the corresponding sub-accommodation cavity and fixed on the inner side of the bottom wall of the shell body 1, the flow of cooling air in the air cooling groove 12 can better bring out the heat generated by each charging and distributing electronic module, which is conducive to further improving the heat exchange efficiency, that is, it is conducive to further improving the air cooling and heat dissipation effect.

[0075] In some embodiments of the present application, Figure 3As shown, there are multiple air cooling grooves 12, and the multiple air cooling grooves 12 are spaced apart along the first direction X, and each air cooling groove 12 extends along the second direction Y. That is to say, the number of air cooling grooves 12 can be multiple, for example, the number of air cooling grooves 12 can be 2, 3, 4, 5, 6, which is set according to actual conditions and is not specifically limited here. As a specific example, Figure 3 As shown, two parallel air cooling grooves 12 are provided on the outer side of the bottom wall of the shell body 1, the two air cooling grooves 12 are spaced apart along the first direction X, and each air cooling groove 12 extends along the second direction Y. When the air cooling module 2 blows cold air to the two air cooling grooves 12, the two air cooling grooves 12 can exchange heat with the charging and distribution module in the shell, which is beneficial to further improve the heat exchange efficiency, that is, it is beneficial to further improve the air cooling heat dissipation effect.

[0076] In some embodiments of the present application, Figure 4 As shown, the air cooling module 2 includes: a fan 21, and the fan 21 is suitable for blowing air toward the air outlet, so that the fan 21 is suitable for blowing air to the air cooling slot 12 through the air outlet.

[0077] Specifically, the air-cooling module 2 has a mounting frame, and the fan 21 is fixedly mounted on the outer wall of the shell body 1 through the mounting frame. Optionally, the mounting frame can be constructed as a fan cover, and the fan cover has an air outlet. When the fan 21 rotates, it can blow air toward the air outlet. At least part of the air outlet is arranged relative to the air cooling groove 12, so as to ensure that the air-cooling module 2 blows cooling air toward the air cooling groove 12, so that the cooling air flows along the air cooling groove 12. With this arrangement, air-cooled heat dissipation of the charging and distribution module in the shell body 1 is realized, and the heat dissipation requirements of the charging and distribution equipment 1000 are met. At the same time, the fan 21 has a simple and reliable structure and low cost.

[0078] It should be noted that the fan 21 is selected to be small in size, with a large air volume and a high rotation speed, so as to improve the fluidity of the cooling air in the air cooling slot 12, which is beneficial to improving the heat dissipation efficiency.

[0079] In some embodiments of the present application, an air guide groove is further included, and the air guide groove is connected between the air outlet and the air cooling groove 12. Specifically, the air guide groove can adopt a guide plate structure, which is specifically set according to actual conditions and is not specifically limited here. In this way, by setting the air guide groove between the air outlet and the air cooling groove 12, the flow rate of cooling air entering the cooling groove can be increased, thereby improving the heat dissipation efficiency.

[0080] In some embodiments of the present application, Figure 7 As shown, it also includes: a cover plate 3, which is arranged on the outer side of the bottom wall of the shell body 1, and the cover plate 3 is suitable for covering at least part of the air cooling module 2 and at least part of the air cooling groove 12, and at least part of the air cooling groove 12 and the cover plate 3 form an air cooling flow channel.

[0081] Specifically, a cover plate 3 can be provided on the outer side of the bottom wall of the shell body 1, and the cover plate 3 is fixedly connected to the bottom wall of the shell body 1, and the connection method includes but is not limited to bolt connection, etc. The cover plate 3 is suitable for covering at least part of the air cooling module 2 and at least part of the air cooling groove 12. It can be understood that when the cover plate 3 covers the air cooling groove 12, the cover plate 3 and the air cooling groove 12 jointly form an air cooling flow channel. With such a configuration, when the air cooling module 2 discharges cooling air into the air cooling groove 12, the air cooling flow channel can ensure the concentration of the air volume flow of the fan 21, thereby helping to improve the heat dissipation efficiency.

[0082] According to the second aspect embodiment of the present application, the charging and distribution equipment 1000 includes: a distribution box 200, a charging and distribution module, and the shell assembly 100 in the first aspect embodiment. The charging and distribution module is arranged in the accommodating cavity 11 of the shell assembly 100 and is electrically connected to the distribution box 200. The distribution box 200 is fixedly connected to the shell assembly 100 to seal the open end of the shell assembly 100.

[0083] According to the charging and distribution equipment 1000 proposed in the second embodiment of the present application, the shell assembly 100 is provided with the above-mentioned shell assembly 100, and the shell assembly 100 of the charging and distribution equipment 1000 sets the air cooling module 2 on the outer wall of the shell body 1. At the same time, the air cooling groove 12 is directly provided on the outer surface of the shell body 1, so that at least part of the air cooling module 2 is arranged opposite to the air cooling groove 12, and the air cooling module 2 is used to blow air to the air cooling groove 12 to achieve heat dissipation and cooling of the charging and distribution module in the shell body 1. In this way, the heat dissipation requirements of the charging and distribution equipment 1000 are met, and the space occupied by the shell assembly 100 is reduced. There is no need to set structures such as heat dissipation teeth, so that the charging and distribution equipment 1000 is relatively small and compact as a whole, which is convenient for the charging and distribution equipment 1000 to be arranged on electrical equipment with narrow space.

[0084] The electric equipment according to the third aspect of the present application includes the charging and distribution equipment 1000 in the second aspect.

[0085] According to the electrical equipment proposed in the third embodiment of the present application, the above-mentioned charging and distribution equipment 1000 is provided, and the shell assembly 100 of the charging and distribution equipment 1000 sets the air cooling module 2 on the outer wall of the shell body 1. At the same time, the air cooling groove 12 is directly provided on the outer surface of the shell body 1, so that at least part of the air cooling module 2 is arranged opposite to the air cooling groove 12, and the air cooling module 2 is used to blow air to the air cooling groove 12 to achieve heat dissipation and cooling of the charging and distribution module in the shell body 1. In this way, the heat dissipation requirements of the charging and distribution equipment 1000 are met, and the space occupied by the shell assembly 100 is reduced.
