[0032] The embodiments of the present application will be described in detail with specific examples. Those skilled in the art can easily understand other advantages and functions of the present application from the content disclosed in the specification. The present application can also be implemented or applied in other different embodiments, and each detail in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following examples and features in the examples can be combined with each other without conflict. It should also be understood that the terms used in the embodiments of the present application are used to describe specific embodiments, but not to limit the protection scope of the present application. The test methods in the following examples are not specified, and are usually performed according to conventional conditions or according to the conditions recommended by the manufacturers.

[0033] When the embodiments give a numerical range, it should be understood that, unless otherwise stated by the utility model, both ends of each numerical range and any one numerical between the two ends can be selected. Unless otherwise defined, all technical and scientific terms used in the utility model are used by the skilled person in the art and the description of the utility model, and any method, equipment and material of the prior art similar or equivalent to the method, equipment and material in the embodiments of the utility model can be used to realize the utility model.

[0034] It should be understood that the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the specification are only for the convenience of clear description, and are not used to limit the scope of the utility model, and the change or adjustment of the relative relationship is also regarded as the scope of the utility model.

[0035] The existing cooling water channel usually uses the way of friction stir welding to fix the cover plate and the shell body, and the friction stir welding uses the heat generated by the friction between the high-speed rotating welding tool and the workpiece to make the welded material locally melt. 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 rotating friction force of the welding tool, and forms a dense solid-phase welding seam under the extrusion of the welding tool. When the cooling water channel of the shell passes through the shell with height difference, the water channel intersection area needs to be established in the shell cavity to realize the water channel across the height difference on the shell. When the cover plate is fixed in the shell cavity by the way of friction stir welding, the stirring head needs to be inserted into the shell cavity to friction the outer periphery of the water channel. On the one hand, the depth of the shell cavity and the height of the stirring head need to be considered. When the depth of the shell cavity is too large, a stirring head with higher height needs to be used, which requires a stirring head with higher strength, resulting in higher cost and inconvenience of the stirring head. On the other hand, when designing the structural layout of the shell cavity, the working avoidance space of the friction stir welding needs to be considered, thereby affecting the structural design of the shell cavity and making the installation design of the shell cavity components complex. On the other hand, the cover plate is fixed in the shell cavity by the way of friction stir welding, which has the risk of liquid leakage due to poor sealing during welding or use.

[0036] Please refer to Figures 1 to 6 The utility model provides a multi-in-one shell, the cooling water channel 300 of the intersection area of first bottom wall 110 and second bottom wall 120 is arranged on the side wall 200, the cooling water channel 300 is separated with the inner chamber, and the separation plate between the cooling water channel 300 and the inner chamber is integrally formed. When designing the structure of the shell cavity, the space occupation of the cover plate 400 in the shell cavity and the reserved operation space during fixing are not considered, which facilitates the structural design of the shell cavity, improves the space utilization of the shell cavity and facilitates the production of the shell.

[0037] Please refer toFigure 1 、 Figure 2 and Figure 4 The all-in-one housing includes a bottom wall 100, side walls 200, cooling water channels 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, and 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. There is also an intersection area between the first bottom wall 110 and the second bottom wall 120 to connect the first bottom wall 110 and the second bottom wall 120 and ensure the strength of the bottom wall 100. A side wall 200 is provided on one side of the bottom wall 100, and the side wall 200 abuts against the first bottom wall 110 and the second bottom wall 120, respectively. A cooling water channel 300 connects the water inlet 111 and the water outlet 121, and is separated from the inner cavity. A partition plate between the cooling water channel 300 and the inner cavity is integrally formed. The cooling water channel 300 at the intersection of the first bottom wall 110 and the second bottom wall 120 is provided on the side wall 200. By providing the cooling water channel 300 at the intersection 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, effectively avoiding the need to reserve space for the friction stir welding operation when providing a cover plate 400 in a conventional shell. This 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. 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 main body of the shell to cover the cooling water channel 300 so that the cooling liquid flows along the cooling water channel 300. The fixing method of the cover plate 400 to the main 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 provided on the outside of the shell, and the cover plate 400 only needs to be provided 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, which requires a reserved space for the stir friction welding operation and is prone to leakage.

[0039] See also Figure 1 In one embodiment, the water inlet 111 is provided 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 provided 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, which cooperate with the bottom wall 100 and the side wall 200 to form a plurality of accommodating cavities for accommodating different components. The number of accommodating cavities is selected and set according to actual needs, such as 2, 3, 4, etc. In one embodiment, there are two accommodating cavities, one of which is located above the first bottom wall 110 and is used to assemble the electrical components of the charger, and the other accommodating cavity is located above the second bottom wall 120 and is used to accommodate the electrical components of the inverter. In other embodiments, the number and function of the accommodating cavities are selected according to actual needs, and reference can also be made to 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 provided on the first bottom wall 110 and is a first groove extending deep into the first bottom wall 110. The first water channel 310 is connected to the water inlet 111. The second water channel 320 is provided on the second bottom wall 120 and is a second groove extending deep into the second bottom wall 120. The second water channel 320 is connected to the water outlet 121. The connecting water channel 330 is provided on the side wall 200 and connects the first water channel 310 and the second water channel 320. By providing the connecting water channel 330 on the side wall 200, the problem of the traditional water channel intersection area needing to be provided in the shell cavity is effectively avoided, which facilitates processing and improves space utilization within 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 covering plate 400 is used to seal the cooling water channel 300 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 housing cavity is provided with a plurality of ribs 500, which serve functions such as securing electrical components or reinforcing the housing. The first water channel 310 includes deep grooves 311 and flat grooves 312. The deep grooves 311 are deeper than the flat grooves 312. The deep grooves 311 are provided on the ribs 500. By providing the deep grooves 311 on at least some of the ribs 500, the cross-sectional area of ​​the cooling water channel 300 is effectively increased while maintaining the strength of the housing. Specifically, the cross-sectional area of ​​the cooling water channel 300 perpendicular to the direction of liquid flow is increased, thereby increasing the water flow rate of the cooling water channel 300.

[0045] See also Figure 5 Furthermore, in one embodiment, the deep grooves 311 extend deep into the ribs 500, allowing the liquid level within the deep grooves 311 to exceed the inner wall of the first bottom wall 110. This shortens the distance between the cooling liquid and the electrical components requiring heat dissipation, increasing the area of ​​space available for the cooling liquid and the required heat dissipation. Furthermore, when the ribs 500 are used to secure electrical components, heat generated by the components can be more quickly transferred to the first water channel 310 through the metal ribs 500, further facilitating thermal exchange with the cooling liquid and improving 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, with the end of the connecting water channel 330 located at the deep groove 311, that is, at the rib 500. The rib 500 has high strength, which can reduce the impact of the connecting water channel 330 on the shell strength, ensuring sufficient shell strength. At the same time, the rib 500 is high, allowing the connecting water channel 330 to penetrate deep into the rib 500, thereby increasing the cross-sectional area of ​​the connecting water channel 330, that is, increasing the cross-sectional area perpendicular to the liquid flow direction of the connecting water channel 330, thereby 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 near 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, 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, and its orientation is aligned with the direction of the rear end of the first water channel 310, facilitating the flow of cooling liquid from the first water channel 310 to the connecting water channel 330. The transverse section 332 is connected to the longitudinal section 331, and its orientation is aligned with the direction from the first bottom wall 110 to the second bottom wall 120, allowing the connecting water channel 330 to connect to the intersection 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 closer to the first water channel 310. During the production of the housing, die casting or other molding methods may be used, which generally requires a mold removal operation. The larger cross-sectional area of ​​the end of the longitudinal section 331 away from the first water channel 310, i.e., the end of the longitudinal section 331 closer to the outside of the sidewall 200, facilitates the mold removal operation. Furthermore, this increased cross-sectional area facilitates the flow of cooling liquid from the end of the longitudinal section 331 closer to the first water channel 310 to the end farther 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. The cooling liquid flow cross-section 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 utility model, the bottom of the first bottom wall 110 is provided with a partition plate 112, the partition plate 112 is arranged in the first water channel 310, the arrangement direction of the partition plate 112 is consistent with the length direction of the first water channel 310, and the end of the partition plate 112 close to the water inlet 111 is abutted on the end of the water channel, and a passage is formed between the end of the partition plate 112 away from the water inlet 111 and the end of the water channel. Thus, after the cooling liquid enters from the water inlet 111, it first flows along one side of the partition plate 112 to the passage, and then flows along the other side of the partition plate 112, thereby improving the flowability and flow coverage of the cooling liquid and effectively ensuring the heat dissipation effect.

[0052] The utility model discloses a second aspect provides a kind of charger shell, including containing cavity, bottom wall, side wall, cooling water channel and cover plate;The containing cavity the containing cavity includes first cavity and second cavity, the first cavity is configured to accommodate charger, the second cavity is configured to accommodate electrical components, second cavity can be used to accommodate inverter, can also be used to accommodate other electrical components, according to actual needs to select;Bottom wall includes first bottom wall and second bottom wall, the first bottom wall is provided with water inlet, the second bottom wall is provided with water outlet, the first bottom wall and the second bottom wall form height difference between;Side wall is arranged in the side of bottom wall, the side wall is respectively with the first bottom wall and the second bottom wall abut;Cooling water channel connects the water inlet with the water outlet, the cooling water channel of the intersection area of the first bottom wall and the second bottom wall is arranged in the side wall;Cover plate is arranged on the outer wall of the shell and is capped in the cooling water channel. By the cooling water channel of the intersection area of the first bottom wall and the second bottom wall being arranged in the side wall, so that cooling water channel is all arranged on the outside of shell, cover plate also only needs to be arranged on the outer wall of shell, the inner cavity of shell is not arranged cover plate, effectively avoid the situation that cover plate needs to reserve friction stir welding operating space in the traditional shell, reduce the space occupation of shell inner cavity, facilitate the inner cavity space design of shell, facilitate the processing of shell. It can also prevent the short circuit or corrosion caused by liquid leakage at the charger.

[0053] It should be noted that the charger shell has two side walls, the side wall in the utility model refers to any one of the two side walls, preferably, the side wall in the utility model refers to the side wall close to the water inlet, to increase the area of cooling liquid flowing on the first bottom wall and improve the heat dissipation efficiency. The charger shell also has two end walls, and the two end walls and the two side walls are arranged around the bottom wall.
