In order to realize the purpose, the utility model discloses the technical scheme who adopts is: an improved power supply heat dissipation structure comprises a machine shell, a heat dissipation fan arranged on the rear side of the machine shell and a fan mesh enclosure arranged on the front side of the heat dissipation fan, wherein the fan mesh enclosure comprises two V-shaped supports arranged at intervals transversely, mounting lugs are formed at the upper end and the lower end of each V-shaped support, the V-shaped supports are fixedly mounted on the left side and the right side of the machine shell respectively, a plurality of square cover frames are erected above the V-shaped supports and sequentially arranged from inside to outside along the center of the machine shell, the diameters of the square cover frames are gradually increased from inside to outside, a heat dissipation air hole is formed in a gap between every two adjacent square cover frames, and the width distance of the heat dissipation air hole is 4-5 mm.

In a further technical scheme, the heat radiation fan is provided with a disc-shaped bottom shell for installing the scattered blades, and the square cover frame positioned on the outermost side at least extends to the outer side of the disc-shaped bottom shell.

In a further technical scheme, the corners of each square cover frame are chamfered C angles, and the maximum distance between the chamfered C angle of the square cover frame positioned on the outermost side and the shell is 2-3 mm.

In a further technical scheme, the square mask frames are coaxially distributed at equal intervals.

In a further technical scheme, the mounting lug is a hook-shaped hanging lug, a plurality of thread counter bores are formed in the corner of the front side of the machine shell respectively, and the hook-shaped hanging lug is locked at the thread counter bore of the machine shell through a screw.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is:

the utility model discloses an improvement fan screen panel's structure avoids screw or other foreign matters to drop into the gap between disc type drain pan and the casing to reduce cost of maintenance and reduce bad production hidden danger.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic view of a partial structure of the present invention.

Detailed Description

The following are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 2, the utility model provides an improved power supply heat dissipation structure, it includes casing 1, set up in the radiator fan of casing 1 rear side and set up in the fan screen panel 2 of radiator fan front side, fan screen panel 2 includes the V type support 20 that two horizontal intervals set up, the relative upper and lower both ends of each V type support 20 are formed with installation ear 200 respectively, each V type support 20 is respectively through fixed mounting in the relative left and right sides of casing 1, a plurality of square cover frames 21 that set gradually from inside to outside along the center of casing 1 are erect to the top of V type support 20, the diameter of a plurality of square cover frames 21 is crescent from inside to outside in proper order, the gap between two adjacent square cover frames 21 forms heat dissipation wind eye 210, the wide distance of heat dissipation wind eye 210 is 4-5 mm. The width distance of the heat dissipation wind eye 210 is preferably 4.4 mm. The cooling fan is provided with a disc-shaped bottom shell (shown by dotted lines in fig. 2) for installing the loose blades, and the square cover frame 21 located at the outermost side at least extends to the outer side of the disc-shaped bottom shell, so that part of foreign matters can be effectively blocked, screws or other foreign matters are prevented from falling into a gap between the disc-shaped bottom shell and the casing, and the maintenance cost is reduced, and the hidden danger of poor production is reduced.
