Description

Fin

Technical field

This utility model relates to the accessory of electronic equipment, relates to a kind of fin.

Background technology

The fin for electronic equipment now is all to be directly installed on electro-heat equipment, then leads to Cross blower fan directly the heat radiation side of fin to be blown, reach the purpose of quick heat radiating, but by Directly fin is blown in fan and makes to produce between the adjacent blades of fin air-swirl, Make a part of dust be accumulated between the adjacent blades of fin, of long duration will make fin Accumulate too much dust between adjacent blades, cause the radiating efficiency of fin to reduce；In order to by electricity Subset ultrathin, method now is in the heat radiation side side of fin by assembling, but This mode limits the necessary thickness of electronic equipment, it is impossible to by electronic equipment ultrathin.

Utility model content

For solving above-mentioned technical problem, we have proposed a kind of fin, its purpose: fan without Be installed together with fin, reduce electronic equipment necessary thickness, the adjacent blades of fin it Between free from dust accumulation.

For reaching above-mentioned purpose, the technical solution of the utility model is as follows:

A kind of fin, including main body and blade, the end face of main body is provided with draw-in groove, blade end Being provided with fixture block, blade assigns into the top of main body, main body and blade by the cooperation of fixture block and draw-in groove Between be provided with copper sheet；

It is circular arc that blade protrudes from the part of body top；

The bottom surface of main body is provided with groove corresponding with electro-heat equipment；

Body side sidepiece is provided with the manhole being connected with blast pipe and spiral shell corresponding with fixed mount Hole；

The outlet air end of manhole is the diminishing taper hole of radius；

Described main body opposite side sidepiece is provided with wind deflector corresponding with the outlet air end of manhole and with solid Determine the corresponding screw of frame.

By technique scheme, body side sidepiece is provided with the manhole being connected with blast pipe And screw corresponding with fixed mount, this fin can be provided separately with blower fan, then blast pipe enters Row connection, decreases the necessary thickness of electronic equipment, and manhole increases this fin Surface area, improves the radiating efficiency of this fin；The outlet air end of manhole is that radius gradually contracts Little taper hole, main body opposite side sidepiece be provided with wind deflector corresponding with the outlet air end of manhole and with The corresponding screw of fixed mount, taper hole can make the wind speed of cooling wind improve, and makes eddy current produce at taper hole Surrounding, is collected in the bottom of wind deflector by dust, makes free from dust between the adjacent blades of fin amass Tire out, it is simple to staff clears up, and cooling wind can be guided on blade, sufficiently by wind deflector Make use of cooling wind, improve the radiating efficiency of this fin.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, under The accompanying drawing used required in embodiment or description of the prior art will be briefly described by face, aobvious and Easily insight, the accompanying drawing in describing below is only embodiments more of the present utility model, for ability From the point of view of the those of ordinary skill of territory, on the premise of not paying creative work, it is also possible to according to these Accompanying drawing obtains other accompanying drawing.

Fig. 1 is the structural representation of a kind of fin disclosed in the utility model；

Fig. 2 is the agent structure schematic diagram of a kind of fin disclosed in the utility model.

Numeral and the corresponding component title represented by letter in figure:

1. main body 11. draw-in groove 12. groove 13. screw 14. manhole 15. wind deflector

2. blade 21. fixture block 3. copper sheet.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment Technical scheme is clearly and completely described, it is clear that described embodiment is only this practicality Novel a part of embodiment rather than whole embodiments.Based on the embodiment in this utility model, The every other reality that those of ordinary skill in the art are obtained under not making creative work premise Execute example, broadly fall into the scope of this utility model protection.

Below in conjunction with schematic diagram, detailed description of the invention of the present utility model is made further details of theory Bright.

As depicted in figs. 1 and 2, a kind of fin, including main body 1 and blade 2, main body 1 End face is provided with draw-in groove 11, and blade 2 end is provided with fixture block 21, and blade 2 is by fixture block 21 and card The cooperation of groove 11 assigns into the top of main body 1, is provided with copper sheet 3 between main body 1 and blade 2, main Being provided with copper sheet 3 between body 1 and blade 2, copper sheet 3 i.e. prevents blade 2 to rock, again can be by heat Amount is transferred on blade 2 by main body 1.

It is circular arc that blade 2 protrudes from the part at main body 1 top, i.e. increases the surface of blade 2 Long-pending, accelerate heat radiation, reduce again taking up room of this fin.

The bottom surface of main body 1 is provided with groove 12 corresponding with electro-heat equipment, it is ensured that this fin can be with Electro-heat equipment directly contacts.

Main body 1 side sidepiece is provided with the manhole 14 being connected with blast pipe, can be by this fin Being provided separately with blower fan, then blast pipe connects, and decreases the necessary thickness of electronic equipment, And manhole 14 increases the surface area of this fin, improve the heat radiation effect of this fin Rate.

The outlet air end of manhole 14 is the diminishing taper hole of radius, and main body 1 opposite side sidepiece sets Having wind deflector 15 corresponding with the outlet air end of manhole 14, taper hole can make the wind speed of cooling wind Improve, make eddy current produce in taper hole surrounding, dust is collected in the bottom of wind deflector 15, makes heat radiation Free from dust accumulation between the adjacent blades of sheet, it is simple to staff clears up, and wind deflector 15 can be by Cooling wind is guided on blade, sufficiently make use of cooling wind, improves the heat radiation effect of this fin Rate.

The both sides sidepiece of main body 1 is provided with screw 13 corresponding with fixed mount, facilitate this fin with Fixed mount connects fixing.

It is exactly construction features and the action effect of a kind of fin, its advantage: decrease electronic equipment Necessary thickness, improve the radiating efficiency of this fin, make nothing between the adjacent blades of fin Dust accumulates, it is simple to staff clears up, and sufficiently make use of cooling wind.

Above-described is only preferred implementation of the present utility model, it is noted that for ability For the those of ordinary skill in territory, on the premise of creating design without departing from this utility model, also may be used To make some deformation and improvement, these broadly fall into protection domain of the present utility model.
