[0032] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the features in the following embodiments and embodiments can be combined with each other without conflict. It should also be understood that the terms used in the embodiments of the present invention are intended to describe specific embodiments, rather than to limit the scope of protection of the present invention. The test methods for which specific conditions are not indicated in the following examples are usually carried out under conventional conditions or according to the conditions recommended by the manufacturers.

[0033] When numerical ranges are given in the embodiments, it should be understood that unless otherwise specified in the present invention, both endpoints of each numerical range and any value between the two endpoints can be selected. Unless otherwise defined, all technical and scientific terms used in the present invention are familiar to those skilled in the art and the description of the present invention, and any method, device and material of the prior art similar or equivalent to the method, device and material in the embodiments of the present invention can also be used to implement the present invention.

[0034] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" etc. used in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships, without substantially changing the technical content, should also be regarded as the scope of implementation of the present invention.

[0035] Existing cooling water channels usually use stir friction welding to fix the cover plate and the shell body. Stir friction welding uses the heat generated by the friction between the high-speed rotating welding tool and the workpiece to partially melt the welded material. When the welding tool moves forward along the welding interface, the plasticized material flows from the front to the rear of the welding tool under the action of the rotating friction force of the welding tool, and forms a dense solid phase weld under the extrusion of the welding tool. When the cooling water channel of the shell passes through the shell with a height difference, it is necessary to establish a water channel intersection area in the inner cavity of the shell to enable the water channel to cross the height difference on the shell. When the cover plate is fixed in the inner cavity of the shell by stir friction welding, the stirring head needs to extend into the shell cavity to rub the outer periphery of the water channel. On the one hand, it is necessary to consider the depth of the inner cavity of the shell and the height of the stirring head. When the depth of the inner cavity of the shell is too large, a stirring head with a larger height needs to be used, thereby requiring a stirring head with a higher strength, resulting in a higher cost and inconvenient processing of the stirring head; on the other hand, when designing the structural layout of the inner cavity of the shell, it is necessary to consider the working avoidance space of the stir friction welding, which affects the structural design of the inner cavity of the shell and makes the installation design of the inner cavity components of the shell complicated; on the other hand, the inner cavity of the shell fixes the cover plate by stir friction welding, and there is a risk of leakage due to poor sealing during welding or use.

[0036] See also Figures 1 to 6 The present invention provides an all-in-one shell, in which a cooling water channel 300 at the intersection of a first bottom wall 110 and a second bottom wall 120 is arranged on a side wall 200, the cooling water channel 300 is separated from the inner cavity, and a partition plate between the cooling water channel 300 and the inner cavity is integrally formed. When designing the structure of the inner cavity of the shell, there is no need to consider the space occupied by the cover plate 400 in the inner cavity of the shell and the reserved operating space when fixed, which facilitates the design of the inner cavity structure of the shell, improves the space utilization of the inner cavity of the shell, and facilitates the production of the shell.

[0037] See also Figure 1 , Figure 2 and Figure 4The all-in-one housing includes a bottom wall 100, a side wall 200, a cooling water channel 300 and a cover plate 400. The bottom wall 100 includes a first bottom wall 110 and a second bottom wall 120, the first bottom wall 110 is provided with a water inlet 111, the second bottom wall 120 is provided with a water outlet 121, a height difference is formed between the first bottom wall 110 and the second bottom wall 120, and an intersection area is also included between the first bottom wall 110 and the second bottom wall 120, so that the first bottom wall 110 and the second bottom wall 120 are connected and the strength of the bottom wall 100 is ensured. The side wall 200 is disposed on one side of the bottom wall 100, and the side wall 200 is respectively in contact with the first bottom wall 110 and the second bottom wall 120; the cooling water channel 300 connects the water inlet 111 and the water outlet 121, the cooling water channel 300 is separated from the inner cavity, and the partition plate between the cooling water channel 300 and the inner cavity is integrally formed, and the cooling water channel 300 in the intersection area of ​​the first bottom wall 110 and the second bottom wall 120 is disposed on the side wall 200. By disposing the cooling water channel 300 in the intersection area of ​​the first bottom wall 110 and the second bottom wall 120 on the side wall 200, the inner cavity of the shell is not provided with a cover plate 400, which effectively avoids the situation that the cover plate 400 is provided in the traditional shell and requires the reserved space for the stir friction welding operation, reduces the space occupied by the inner cavity of the shell, facilitates the design of the inner cavity space of the shell, and facilitates the processing of the shell.

[0038] In one embodiment, the cooling water channel 300 is provided with an opening facing away from the inner cavity on the bottom wall 100 and the side wall 200, and the shell includes a cover plate 400, which is provided on the outer wall of the shell and covers the opening of the cooling water channel 300. The cover plate 400 cooperates with the body of the shell to cover the cooling water channel 300 so that the cooling liquid flows along the cooling water channel 300, and the fixing method of the cover plate 400 and the body of the shell includes but is not limited to stir friction welding, preferably stir friction welding, to ensure the sealing of the cooling water channel 300. By providing the cooling water channel 300 with an opening facing away from the inner cavity, the cooling water channel 300 is arranged on the outside of the shell, and the cover plate 400 only needs to be arranged on the outer wall of the shell. The inner cavity of the shell is not provided with a cover plate 400, which effectively avoids the problem that the cover plate 400 is provided in the traditional shell, and the stir friction welding operation space needs to be reserved and is easy to leak.

[0039] See also Figure 1 In one embodiment, the water inlet 111 is disposed on the side of the first bottom wall 110 to keep the bottom surface of the first bottom wall 110 flat and facilitate the installation of the housing. In other embodiments, the water inlet 111 may also be disposed on the bottom surface of the first bottom wall 110.

[0040] It should be noted that the multi-in-one shell has two side walls 200. The side wall 200 in the present invention refers to any one of the two side walls 200. Preferably, the side wall 200 in the present invention refers to the side wall 200 closer to the water inlet 111, so as to increase the area through which the cooling liquid flows on the first bottom wall 110 and improve the heat dissipation efficiency.

[0041] In one embodiment of the present invention, the multi-in-one housing further has two other end walls and a partition wall to cooperate with the bottom wall 100 and the side wall 200 to form a plurality of accommodating chambers for accommodating different components. The number of accommodating chambers is selected and set according to actual needs, such as 2, 3, 4, etc. In one embodiment, there are two accommodating chambers, one of which is located above the first bottom wall 110 for assembling the electrical components of the charger, and the other accommodating chamber is located above the second bottom wall 120 for accommodating the electrical components of the inverter. In other embodiments, the number and function of the accommodating chambers are selected according to actual needs, and reference can also be made to the existing multi-in-one housings, which will not be elaborated in this application.

[0042] See also Figure 4 In an exemplary embodiment of the present invention, the cooling water channel 300 includes a first water channel 310, a second water channel 320 and a connecting water channel 330. The first water channel 310 is arranged on the first bottom wall 110, the first water channel 310 is a first groove deep into the first bottom wall 110, and the first water channel 310 is connected to the water inlet 111. The second water channel 320 is arranged on the second bottom wall 120, the second water channel 320 is a second groove deep into the second bottom wall 120, and the second water channel 320 is connected to the water outlet 121. The connecting water channel 330 is arranged on the side wall 200, and the connecting water channel 330 connects the first water channel 310 and the second water channel 320. By arranging the connecting water channel 330 on the side wall 200, the problem that the traditional water channel intersection area needs to be arranged in the inner cavity of the shell is effectively avoided, which is convenient for processing and convenient for space utilization in the shell.

[0043] See also Figures 1 to 3 In an exemplary embodiment of the present invention, the cover plate 400 includes a first cover plate 410, a second cover plate 420 and a connecting cover plate 430, wherein the first cover plate 410 covers the first water channel 310, the second cover plate 420 covers the second water channel 320, and the connecting cover plate 430 covers the connecting water channel 330. The cooling water channel 300 is sealed by the cover plate 400 to prevent leakage of the cooling liquid in the cooling water channel 300.

[0044] See also Figure 5In an exemplary embodiment of the present invention, the inner cavity of the shell is provided with a plurality of ribs 500, and the ribs 500 have the functions of fixing electrical components or strengthening the strength of the shell. The first water channel 310 includes a deep groove 311 and a flat groove 312, the depth of the deep groove 311 is greater than the depth of the flat groove 312, and the deep groove 311 is provided at the rib 500. By providing the deep groove 311 at at least part of the rib 500, the cross-sectional area of ​​the cooling water channel 300 is effectively increased while ensuring the strength of the shell, that is, the cross-sectional area of ​​the cross section of the cooling water channel 300 perpendicular to the liquid flow direction is increased, thereby increasing the water flow of the cooling water channel 300.

[0045] See also Figure 5 Furthermore, in one embodiment, the deep groove 311 extends deep into the rib plate 500, so that the liquid level in the deep groove 311 can exceed the inner wall of the first bottom wall 110, shortening the distance between the cooling liquid and the required heat dissipation electrical components, and increasing the area of ​​the cooling liquid and the required heat dissipation space. At the same time, if the rib plate 500 is used to fix the electrical components, the heat generated by the electrical components can be transferred to the first water channel 310 more quickly through the metal rib plate 500, which is more conducive to the cooling liquid to complete the thermal interaction and improve the heat dissipation efficiency.

[0046] See also Figure 5 and Figure 6 In an exemplary embodiment of the present invention, the connecting water channel 330 is connected to the deep groove 311, and the end of the connecting water channel 330 is arranged at the deep groove 311, that is, the end of the connecting water channel 330 is arranged at the rib 500, and the rib 500 has a high strength, which can reduce the influence of the connecting water channel 330 on the strength of the shell, and ensure that the shell has sufficient strength. At the same time, the height of the rib 500 is high, and the connecting water channel 330 can go deep into the rib 500, thereby increasing the cross-sectional area of ​​the connecting water channel 330, that is, increasing the cross-sectional area of ​​the cross section perpendicular to the liquid flow direction of the connecting water channel 330, and ensuring the fluidity and flow rate of the cooling liquid.

[0047] See also Figure 5 In an exemplary embodiment of the present invention, the cross-sectional area of ​​the connection between the connecting water channel 330 and the deep groove 311 is larger than the cross-sectional area of ​​the deep groove 311, that is, the liquid in the connecting water channel 330 close to the deep groove 311 can have a larger cross-sectional area than the liquid in the deep groove 311, which is more conducive to the cooling liquid flowing from the deep groove 311 to the connecting water channel 330, thereby ensuring the passability of the cooling liquid.

[0048] See also Figure 5 and Figure 6In an exemplary embodiment of the present invention, the connecting water channel 330 includes a longitudinal section 331, a transverse section 332 and a through section 333. The longitudinal section 331 is connected to the first water channel 310. The direction of the longitudinal section 331 is consistent with the direction of the tail end of the first water channel 310, which is conducive to the cooling liquid flowing from the first water channel 310 to the connecting water channel 330. The transverse section 332 is connected to the longitudinal section 331. The setting direction of the transverse section 332 is consistent with the direction from the first bottom wall 110 to the second bottom wall 120, so that the connecting water channel 330 connects the intersection area of ​​the first bottom wall 110 and the second bottom wall 120. One end of the through section 333 is connected to the transverse section 332, and the other end penetrates the side wall 200 and extends to communicate with the second water channel 320. The through section 333 penetrates downward from the end of the transverse section 332 to the second bottom wall 120 and communicates with the second water channel 320, so that the connecting water channel connects the first water channel 310 and the second water channel 320, so that the cooling water channel 300 spans the height difference between the first bottom wall 110 and the second bottom wall 120.

[0049] In an exemplary embodiment of the present invention, the cross-sectional area of ​​the end of the longitudinal section 331 away from the first water channel 310 is larger than the cross-sectional area of ​​the end of the longitudinal section 331 close to the first water channel 310. When producing the shell, die casting or other molding methods can be used, and generally a mold removal operation is required. The cross-sectional area of ​​the end of the longitudinal section 331 away from the first water channel 310, that is, the end of the longitudinal section 331 close to the outer side of the side wall 200, is larger, which can facilitate the mold removal operation. At the same time, by increasing the cross-sectional area, it is more conducive to the cooling liquid to flow from the end of the longitudinal section 331 close to the first water channel 310 to the end away from the first water channel 310.

[0050] See also Figure 5 In an exemplary embodiment of the present invention, the wall thickness S1 of the side wall 200 at the through section 333 is greater than the wall thickness S2 of the side wall 200 at the transverse section 332, and the flow cross-section of the cooling liquid at the through section 333 is perpendicular to the side wall 200. By increasing the wall thickness S1 of the side wall 200 at the through section 333, the flow cross-sectional area of ​​the cooling liquid at the through section 333 can be effectively increased, thereby ensuring the fluidity of the cooling liquid and improving the heat dissipation efficiency.

[0051] See also Figure 4In an exemplary embodiment of the present invention, a partition 112 is disposed at the bottom of the first bottom wall 110. The partition 112 is disposed in the first water channel 310. The direction in which the partition 112 is disposed is consistent with the length direction of the first water channel 310. One end of the partition 112 close to the water inlet 111 abuts against the end of the water channel, and a channel is formed between one end of the partition 112 away from the water inlet 111 and the end of the water channel. As a result, after the cooling liquid enters from the water inlet 111, it first flows along one side of the partition 112 to the channel, and then flows along the other side of the partition 112, thereby improving the fluidity and flow coverage of the cooling liquid and effectively ensuring the heat dissipation effect.

[0052] The second aspect of the present invention provides a charger housing, comprising a accommodating chamber, a bottom wall, a side wall, a cooling water channel and a cover plate; the accommodating chamber comprises a first chamber and a second chamber, the first chamber is configured to accommodate the charger, the second chamber is configured to accommodate electrical components, and the second chamber can be used to accommodate an inverter or other electrical components, which can be selected according to actual needs; the bottom wall comprises a first bottom wall and a second bottom wall, the first bottom wall is provided with a water inlet, the second bottom wall is provided with a water outlet, and a height difference is formed between the first bottom wall and the second bottom wall; the side wall is provided on one side of the bottom wall, and the side wall is respectively abutted against the first bottom wall and the second bottom wall; the cooling water channel connects the water inlet and the water outlet, and the cooling water channel in the intersection area of ​​the first bottom wall and the second bottom wall is provided on the side wall; the cover plate is provided on the outer wall of the housing and covers the cooling water channel. By setting the cooling water channel at the intersection of the first bottom wall and the second bottom wall on the side wall, the cooling water channels are all set on the outside of the shell, and the cover plate only needs to be set on the outer wall of the shell. The inner cavity of the shell is not provided with a cover plate, which effectively avoids the situation that the traditional shell needs to reserve a stir friction welding operation space when setting a cover plate, reduces the space occupied by the inner cavity of the shell, facilitates the design of the inner cavity space of the shell, and facilitates the processing of the shell. It can also prevent the occurrence of short circuit or corrosion caused by liquid seepage at the charger.

[0053] It should be noted that the charger housing has two side walls. The side wall in the present invention refers to any one of the two side walls. Preferably, the side wall in the present invention refers to the side wall closer to the water inlet, so as to increase the area through which the cooling liquid flows on the first bottom wall and improve the heat dissipation efficiency. The charger housing also has two end walls, and the two end walls and the two side walls are respectively arranged around the bottom wall.

[0054] In the multi-in-one shell provided by the present invention, the cooling water channel in the intersection area of ​​the first bottom wall and the second bottom wall is arranged on the side wall, so that the exposed area of ​​the cooling water channel is entirely located on the outside of the shell, and the cover plate only needs to be arranged on the outer wall of the shell. When designing the structure of the inner cavity of the shell, it is not necessary to consider the space occupied by the cover plate in the inner cavity of the shell and the reserved operating space when fixed, which facilitates the design of the inner cavity structure of the shell and improves the space utilization of the inner cavity of the shell; the inner cavity of the shell is not provided with a cover plate to prevent the risk of liquid seepage at the connection between the cover plate and the shell body, thereby improving safety and durability.
