As an example, the second protrusion 122 may be a hemispherical protrusion as shown in Figure 5 . Of course, the shape of the second protrusion 122 is not limited to this, as long as it can satisfy the snap connection with the first card hole 111a. For example, the shape of the second protrusion 122 may be a prismatic shape, a pyramidal shape or a cylindrical shape other than the hemispherical shape.
[0044] As Figure 5 shown, the second protrusion 122 is snapped into the first card hole 111a. Specifically, the second protrusion 122 is disposed in the first card hole 111a, and a part of the circumferential side wall of the second protrusion 122 abuts against the inner circumferential surface of the first card hole 111a.
[0045] As Figure 7 shown, in some embodiments, the second wall 121 includes a second body 1211 and a first folded edge 1212.

The first folded edge 1212 is connected to one side edge of the second body 1211 away from the fourth wall 123 and is bent relative to the second body 1211. The bending direction of the first folded edge 1212 is generally parallel to the plane where the fourth wall 123 is located. Among them, the second protrusion 122 is disposed on the surface of the first folded edge 1212 facing away from the accommodation space 10a.
[0046] AsFigure 8 As shown, in some embodiments, the fourth wall 123 includes a fourth body 1231 and a second bending portion 1232. The fourth body 1231 is disposed at an angle with respect to the second body 1211, and the fourth body 1231 is connected to a side edge of the second body 1211 away from the second protrusion 122. The second bending portion 1232 is connected to a side edge of the fourth body 1231 away from the second wall 121, and the second bending portion 1232 is engaged in the third locking hole 1133.
[0047] Specifically, the second bending portion 1232 includes a first bending sub-portion 12321 connected to a side edge of the fourth body 1231 away from the second wall 121 and a second bending sub-portion 12322 connected to the first bending sub-portion 12321. Among them, along the length direction L of the housing, the length of the second bending sub-portion 12322 is greater than the length of the first bending sub-portion 12321. The first bending sub-portion 12321 can be engaged in the first sub-hole 11331, and the second bending sub-portion 12322 can be engaged in the second sub-hole 11332. The portion of the second bending sub-portion 12322 that extends beyond the first bending sub-portion 12321 can abut against the inner side wall of the third wall 113.
[0048] As Figure 8 shown, for facilitating the assembly and positioning of the first housing 11 and the second housing 12, in some embodiments, the number of the second bending portions 1232 is at least two. Along the length direction L of the housing 10, at least two second bending portions 1232 are spaced apart on a side edge of the fourth body 1231 away from the second wall 121.
[0049] The number of the third locking holes 1133 is at least two. The number and positions of the third locking holes 1133 correspond one-to-one to the number and positions of the second bending portions 1232, and one second bending portion 1232 is engaged in one third locking hole 1133.
[0050] The assembly process of the housing 10 of the server power supply of the present application is as follows:

[0053] Finally, after the second housing 12 rotates, the other side of the first housing 11 and the other side of the second housing 12, and when the second housing 12 abuts against the first housing 11, press the second housing 12 so that the second protrusion 122 is snapped into the first card hole 111a, and the first protrusion 112 is snapped into the second card hole 121a, realizing the splicing of the first housing 11 and the second housing 12.
[0054] In summary, for the server power supply of the present application, by snapping the second protrusion 122 into the first card hole 111a and the first protrusion 112 into the second card hole 121a, the first housing 11 and the second housing 12 are mutually constrained in the width direction W and the thickness direction H of the housing. Therefore, the number of threaded fasteners 40 used to fix the outer shell 10 on the server power supply can be reduced, facilitating the disassembly and assembly of the outer shell 10.
[0055] It can be understood that the specific structures of the first housing 11 and the second housing 12 are not limited thereto, and the two can be adaptively adjusted according to actual usage requirements, and can satisfy that the second protrusion 122 is snapped into the first card hole 111a and the first protrusion 112 is snapped into the second card hole 121a, so that the first wall 111 and the second wall 121 are spliced at an angle. In some other embodiments, the first housing 11 and the third housing can be detachably connected by other means than the second bending portion 1232 being clamped in the third card hole 1133. For example, the first housing 11 and the third housing are respectively provided with a pivot and a pivot hole that are cooperatively pivoted, or the first housing 11 and the third housing are respectively provided with a first hinge member and a second hinge member that are cooperatively hinged.
[0056] In addition, the shape of the outer shell 10 is not limited thereto, and it can be adaptively adjusted according to the arrangement position of the internal electrical components.

[0060] In this technical solution, by providing the air outlet, the air inlet, and the heat dissipation component, the heat dissipation component can dissipate heat from the power conversion component, and the heat is taken away through air flow, which can improve the heat dissipation in the accommodation space 10a.
[0061] In some embodiments, both the air outlet and the air inlet are in communication with the interior of the accommodation space 10a to form an air flow channel. Both the heat dissipation component and the power conversion component are provided in the air flow channel.

The power conversion board 21 is fixedly provided on one inner wall surface of the housing 10. The heat dissipation component includes a radiator 51, and the radiator 51 is installed on the power conversion board 21.
