[0006] Optionally, the fan connector has two fan locking portions, and the two fan locking portions are respectively parallel to the top wall and the first extension portion and are respectively locked to the fan body and one of the first extension portions.

[0007] Optionally, the top wall has a plurality of heat dissipation holes, and the fan body is adjacent to the top wall.

[0008] Optionally, an electrical connection interface is further included, which is arranged on one of the two first direction side walls.

[0009] Optionally, the first direction side wall has a plurality of heat dissipation holes.

[0010] Optionally, it also includes a circuit component, including a circuit board, a supporting plate and a plurality of supporting plate connectors, the circuit board is locked to the supporting plate, and the supporting plate connectors are respectively connected to the supporting plate and one of the first extensions.

[0011] Optionally, the supporting plate is provided with a plurality of nut columns, and the circuit board is locked to the supporting plate via the nut columns.

[0012] Optionally, the supporting plate connecting members are parallel to the first extending portions and are respectively locked to the first extending portions.

[0013] Thus, the power supply for a computer of the present invention covers the first extension part through the upper cover member, so that the numerous screw holes located in the first extension part are hidden.

[0044] In order to fully understand the present invention, the present invention is described in detail through the following specific embodiments and in combination with the accompanying drawings. Those skilled in the art can understand the purpose, characteristics and effects of the present invention from the contents disclosed in this specification. It should be noted that the present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the inventive point of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual dimensions. The following embodiments will further describe the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the claims of the present invention. The description is as follows:

[0045] like Figure 1 and Figure 2 As shown, a power supply 100 for a computer according to an embodiment of the present invention comprises a base component 1 , an upper cover component 2 and a fan component 3 .

[0046] The base member 1 includes a bottom wall 11 and two first direction side walls 12 . The two first direction side walls 12 are parallel to each other and are respectively connected to two ends of the bottom wall 11 in the first direction d1 . Each first direction side wall 12 has two first extension portions 121 . The first extension portions 121 extend along the first direction d1 .

[0047] The upper cover member 2 includes a top wall 21 and two second direction side walls 22, the two second direction side walls 22 are parallel to each other and are respectively connected to the two ends of the top wall 21 in the second direction d2 and respectively cover the first extension portions 121. The top wall 21 and the bottom wall 11 are parallel to each other, the second direction d2 is perpendicular to the first direction d1, and the first direction d1 and the second direction d2 are parallel to the bottom wall 11 and the top wall 21, that is, the base member 1 and the upper cover member 2 cooperate with each other to form a hollow hexahedral structure.

[0048] The fan member 3 includes a fan body 31 and a plurality of fan connectors 32. The fan body 31 is located in the space formed by the base member 1 and the upper cover member 2, preferably close to the top wall 21 so as to blow airflow from the heat dissipation holes 211 of the top wall 21. The plurality of fan connectors 32 are respectively connected to the fan body 31 and one of the first extensions 121 to fix the fan body 31 to the first extension 121. In detail, in the present embodiment, the number of the fan connectors 32 is four, which respectively correspond to the first extensions 121 located on both sides of the two first-direction side walls 12, and are locked to the locking holes 121a of the first extensions 121 by means of screws or other locking members. The position and height of the locking hole 121a can be changed accordingly as needed to change the position where the fan body 31 is fixed to the first extension 121.

[0049] With the above structure, during assembly, the fan body 31 is fixed to the locking hole 121a of the first extension part 121 by using the fan connector 32, so that the fan body 31 can be fixed. At this time, the screw connection of the fan connector 32 is located on the first extension part 121, and the first extension part 121 is covered by the two second direction side walls 22 of the upper cover member 2, so that the screw connection of the fan connector 32 is hidden (such as Figure 1 As shown). Therefore, the outer shell of the power supply 100 for a computer of the present invention can move in the first direction d1 (e.g., install) by using a smooth and flat surface to contact other devices, and can move smoothly, avoiding excessive friction and vibration, providing excellent installation quality, and having a more beautiful appearance, reducing the possibility of causing psychological discomfort to specific personnel.

[0050] Furthermore, in this embodiment, if Figure 3As shown, the fan connector 32 has two fan locking parts 321 and 322, and the two fan locking parts 321 and 322 are respectively parallel to the top wall 21 and the first extension part 121 and are respectively locked to one of the fan body 31 and the first extension part 121. In detail, the fan locking part 321 is parallel to the top wall 21 and is locked to the fan body 31 with a screw or other locking part; the fan locking part 322 is parallel to the first extension part 121 and is locked to one of the locking holes 121a in the first extension part 121 with a screw or other locking part. Preferably, the fan locking parts 322 of each fan connector 32 can be symmetrically provided in two groups, so that one of the fan locking parts 322 can be flexibly selected for locking.

[0051] Furthermore, in this embodiment, the top wall 21 has the aforementioned plurality of heat dissipation holes 211 , and the fan body 31 is adjacent to the top wall 21 so as to blow airflow from the heat dissipation holes 211 nearby.

[0052] Furthermore, in this embodiment, if Figure 2 As shown, the power supply 100 for a computer further includes a circuit component 4. The circuit component 4 includes a circuit board 41, a support plate 42, and a plurality of support plate connectors 43. For ease of understanding, the electronic components on the circuit board 41 and other conventional movement structures are omitted. The circuit board 41 is fastened to the support plate 42 by means of fasteners such as screws, and is supported by the support plate 42. The support plate 42 has better rigidity than the softer circuit board 41, and is usually a thin metal plate. The plurality of support plate connectors 43 are respectively connected to the support plate 42 and one of the plurality of first extensions 121. Specifically, in the present embodiment, the number of the support plate connectors 43 is four (the actual number may vary according to demand), which respectively correspond to the first extensions 121 located on both sides of the two first direction side walls 12, and are fastened to the fastening holes 121b of the first extensions 121 by means of fasteners such as screws. The position and height of the locking hole 121b can be changed accordingly as needed to change the position where the supporting plate 42 is fixed to the first extension portion 121. Generally speaking, the height position of the locking hole 121b is closer to the bottom wall 11, and the height position of the locking hole 121a is closer to the top wall 21, but the present invention is not limited thereto.

[0053] During assembly, the circuit board 41 is fastened to the support plate 42 using screws or other fasteners, and the support plate connector 43 is fastened to the fastening hole 121b of the first extension 121 (the above two steps are not limited in order), so as to complete the fixing of the circuit board 41. At this time, the screw connection of the circuit board 41 is located on the support plate 42 and is difficult to be observed from the appearance of the power supply 100 for a computer; and because the screw connection of the support plate connector 43 is located on the first extension 121, and the first extension 121 is covered by the two second-direction side walls 22 of the upper cover member 2, the screw connection of the support plate connector 43 is hidden (such as Figure 1 As shown). Therefore, the outer shell of the power supply 100 for a computer of the present invention can move in the first direction d1 (e.g., install) by using a smooth and flat surface to contact other devices, and can move smoothly, avoiding excessive friction and vibration, providing excellent installation quality, and having a more beautiful appearance, reducing the possibility of causing psychological discomfort to specific personnel.

[0054] Furthermore, in this embodiment, the power supply 100 for a computer further includes an electrical connection interface 5, which is disposed on one of the two first-direction side walls 12. The electrical connection interface 5 is, for example, a power switch or a power socket, etc., which is electrically connected to the circuit board 41 and / or the fan body 31. Since the first-direction side wall 12 is usually not set as a moving contact surface, the electrical connection interface 5 with an undulating surface is suitable for being disposed on the first-direction side wall 12, but not suitable for the second-direction side wall 22 which is required to be smooth and flat.

[0055] Furthermore, in this embodiment, the first direction side wall 12 also has a plurality of heat dissipation holes 122 , and the airflow generated by the fan body 31 can also flow out from the heat dissipation holes 122 and take away the heat energy generated by the circuit board 41 .

[0056] Furthermore, if Figure 2 As shown, in this embodiment, the support plate 42 is provided with a plurality of nut columns 421, and the circuit board 41 is locked to the support plate 42 through these nut columns 421. The number of the nut columns 421 is not limited, and in this embodiment, the number is four, and they are arranged at the four corners of the support plate 42.

[0057] Furthermore, if Figure 2 As shown, in this embodiment, a plurality of supporting plate connecting members 43 are parallel to the first extending portions 121 and are respectively locked to the first extending portions 121. However, the present invention is not limited thereto, and the supporting plate connecting members 43 may have other types.

[0058] The present invention has been disclosed above with preferred embodiments, but those skilled in the art should understand that the embodiments are only used to describe the present invention and should not be interpreted as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the embodiments should be considered to be within the scope of the present invention. Therefore, the protection scope of the present invention shall be based on the scope of the content defined in the claims.
