The description is as follows:

[0020] like Figures 1 to 5 As shown, a power supply 100 with a cooling fan according to an embodiment of the present invention is used in a preferred embodiment to supply power to a computer host, but the present invention is not limited to this application. Any environment in which a power supply is used belongs to the scope of protection of the present invention. The power supply 100, in the embodiment described below, includes a first housing 10, a fan body 20, a plurality of connectors 30, and a second housing 40, wherein:

[0021] The first housing 10, as Figure 1 As shown, it includes a first bottom wall 11 and two first side walls 12, the two first side walls 12 are respectively perpendicular to the first bottom wall 11 and parallel to each other, and the two first side walls 12 are connected to the first bottom wall 11 on both sides of the first direction X, and the two first side walls 12 respectively have two first extension portions 121 extending toward each other along the first direction X, that is, the two first extension portions 121 of any first side wall 12 extend toward the direction of the other first side wall 12.

[0022] The fan body 20 is as follows Figure 4As shown, it is disposed in a space 13 formed by the first housing 10. The plurality of connectors 30, in one embodiment, are two and are disposed on both sides of the fan body 20, respectively. However, the present invention is not limited to two connectors 30. In different embodiments, the connector 30 may be one or more than two. Figure 1 As shown, each connecting member 30 includes a connecting portion 31 and two fixing portions 32. The connecting portion 31 is in a long strip shape, and the two fixing portions 32 are connected at both ends of the connecting portion 31. The fan body 20 in the space 13 is fixed to the first extension portions 121 on both sides of the first side wall 12 by the fixing components 50 of each fixing portion 32 (see FIG. Figure 3 , 4 As shown), the connecting portion 31 is supported between the two fixing portions 32 along the side of the fan body 20, so that the fan body 20 is fixed to the first housing 10.

[0023] In one embodiment, the fixing component 50 is a screw, and the first extension portion 121 has a locking hole 121a. The position and height of the locking hole 121a on the first extension portion 121 can be changed accordingly as needed to change the position where the fan body 20 is fixed to the first extension portion 121. However, the present invention is not limited to the fixing component 50 being a screw, and other fixing components (such as rivets) also fall within the scope of the fixing component described in the present invention.

[0024] The second housing 40 includes a second bottom wall 41 and two second side walls 42. The two second side walls 42 are respectively perpendicular to the second bottom wall 41 and parallel to each other, and the two second side walls 42 are respectively connected to the two ends of the second bottom wall 41 in the second direction Y. Figure 1 As shown, the first direction X and the second direction Y are orthogonal and parallel to the first bottom wall 11 and the second bottom wall 41. When the fan body 20 is fixed to the first housing 10 as described above, the second housing 40 covers the first extensions 121 and the outside of the connecting members 30 with the second bottom wall 41 and the two second side walls 42, and the second housing 40 and the first housing 10 are fixed by screws 60. At this time, the fan body 20 disposed in the space 13 is covered by the second housing 40, so that the fan body 20 and the fixing assembly 50 fixing it are hidden in the second housing 40 and are not exposed. In one embodiment, the first bottom wall 11 and the two second bottom walls 41 of the second housing 40 are a single plate, and after sheet metal processing such as Figure 2 , 4 The second shell 40 is shown in a bent shape, but the present invention is not limited thereto. The second shell 40 may also be an assembled component, for example, the first bottom wall 11 and the two second bottom walls 41 are three independent plate components assembled by screws or welding.

[0025] In one embodiment, the number of the connecting members 30 is as follows: Figure 1Two first extensions 121 are shown, corresponding to the first sidewalls 12 on both sides, and are locked to the locking holes 121a of the first extensions 121 by the fixing assembly 50. The position and height of the locking holes 121a can be changed accordingly as needed to change the position of the fan body 20 fixed to the first extension 121.

[0026] In one embodiment of the present invention, each fixing portion 32 includes a first locking portion 321 and a second locking portion 322. The first locking portion 321 is used to be locked to the fan body 20, and the second locking portion 322 is used to be locked to each first extension portion 121. In one embodiment of the present invention, each fixing portion 32 has an opening 323. The position of the opening 323 in the fixing portion 32 is different from that of the first locking portion 321 and the second locking portion 322. The provision of the opening 323 can save the material of the connecting member 30.

[0027] In detail, Figure 1 As shown, the fan body 20 is rectangular and has screw holes 21 at each of the four corners. Figure 2 As shown, the first locking portion 321 of the fixing portion 32 has a through hole 321a, and the length of the connecting portion 31 is suitable for allowing the through holes 321a of the first locking portions 321 at both ends thereof to be aligned with the screw holes 21 at two adjacent corners of the fan body 20 at one time, so that the user can respectively penetrate the through holes 321a of the two fixing components 50 and lock them in the corresponding screw holes 21.

[0028] Furthermore, if Figure 2 , 3 As shown, the second locking portion 322 has a screw hole 322a. When the connecting member 30 is locked to the fan body 20 with the first locking portion 321 as described above, and the fan body 20 is moved into the space 13, the screw hole 322a of the second locking portion 322 can be aligned with the locking hole 121a of the first extension portion 121, so that the user can respectively pass the two fixing components 50 through the locking holes 121a and lock them in the corresponding screw holes 322a.

[0029] In one embodiment of the present invention, the first housing 10 is a bottom housing, and the second housing 40 is an upper cover. Furthermore, the second bottom wall 41 has a plurality of heat dissipation holes 411, and the fan body 20 is relatively close to the second bottom wall 41 in the first housing 10, that is, the fan body 20 is close to the heat dissipation holes 411 (see Figure 4 As shown), when the fan body 20 is in operation, the airflow can be directly directed to the heat dissipation hole 411, so that the airflow can quickly circulate with the outside to dissipate heat.

[0030] In one embodiment of the present invention, an electrical connection port 70 is further included. The electrical connection port 70 is disposed on one of the two first side walls 12 . The electrical connection port 70 is, for example, a socket or a switch for connecting an external power source (such as AC power) as a power source for the power supply 100 .

[0031] In one embodiment of the present invention, one of the two first side walls 12 has a plurality of heat dissipation holes 122 to cooperate with the heat dissipation holes 411 of the second bottom wall 41 so that the gas in the space 13 can flow smoothly with the outside. Furthermore, the other first side wall 12 has a plurality of mounting holes 123, and the mounting holes 123 can be passed through by the power connector (not shown in the figure). In one embodiment of the present invention, the first side wall 12 is provided with a plurality of nut columns 124, and the nut columns 124 are used to lock the circuit board (not shown in the figure) on the first side wall 12.

[0032] When assembling the power supply 100 of the above embodiment, Figure 2 As shown, the user can move the connecting member 30 toward one side of the fan body 20, so that the user can hold the connecting portion 31 and align the through holes 321a of the first locking portions 321 at both ends with the screw holes 21 at the two corners of the fan body 20 respectively, and pass the two fixing components 50 through the through holes 321a respectively and lock them in the screw holes 21. This action only needs to be performed twice to fix the four fixing portions 32 of the two connecting members 30 at the four corners of the fan body 20.

[0033] As above, Figure 3 , 4 As shown, when the connecting member 30 is assembled on the fan body 20, the user places the connecting member 30 into the space 13 with the fan body 20, and aligns the screw hole 322a of the second locking portion 322 with the locking hole 121a of the first extension portion 121. The user can then pass four fixing components 50 through the locking holes 121a respectively and lock them in the corresponding screw holes 322a to complete the assembly of the fan body 20 on the first housing 10; then, the user can cover the first housing 10 with the second housing 40, and at this time, the connecting member 30 and the first extension portion 121 locked by the fixing component 50 are covered by the second bottom wall 41 and the two second side walls 42 of the second housing 40, that is, Figure 5 , 6 As shown, the fixing assembly 50 and the locking connector 30 and the first extension portion 121 are now hidden in the second housing 40 and are not exposed.

[0034] It is not difficult to find from the above description that the advantage of the present invention is that the power supply 100 with a cooling fan of the present invention can be covered by the second shell 40 on the assembled multiple first extensions 121 and multiple connectors 30, so that the fixing component 50 used to fix the fan body 20 can be hidden by the second shell 40 and not exposed, thereby avoiding interference, friction, vibration and other situations with other components due to the exposure of the fixing component 50, which may affect the installation quality, and the appearance of the power supply 100 will not appear abrupt due to the exposure of the fixing component 50.

[0035] Furthermore, each connector 30 of the present invention has a connecting portion 31 between its two fixing portions 32. When the fixing portion 32 is fixed between the fan body 20 and the first extension portion 121, the two fixing portions 32 of the connector 30 can structurally support each other through the connecting portion 31, so that the assembly of the fan body 20 on the power supply 100 can be firm and stable. The two fixing portions 32 are also supported by the connecting portion 31 to help balance the assembly of the fan body 20 on the power supply 100, that is, the two fixing portions 32 are supported by the connecting portion 31 to achieve the effect of increasing the overall structural safety of the power supply 100.

[0036] The present invention has been disclosed in the above with 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 included in the scope of the present invention. Therefore, the protection scope of the present invention shall be based on the definition of the claims.
