Description

The composite set of fan and fin

Technical field

The utility model relates to the composite set of a kind of fan and fin, refers to a kind of fan of computer cpu and the composite set of fin especially.

Background technology

As everyone knows, the central processing unit of computer (Central Process Unit, hereinafter to be referred as CPU) when starting computing, can produce high temperature, if can not be with its timely eliminating, then can influence its performance, even burn, especially the arithmetic speed fast heat that CPU produced of healing is higher, and its influence is more remarkable; Therefore, any host computer all must be provided with heat abstractor to get rid of the heat that CPU was produced.

Generally for the arithmetic speed heat abstractor design of CPU faster, mainly be that the fin with plurality of fins directly is set on CPU, and on this fin, fan is set, the most heat that is produced during this CPU computing is absorbed by this fin, and this CPU starts fan running simultaneously and blows fin to reach thermolysis.Traditionally with the mode of fan and fin combination, be that housing at fan is provided with a plurality of holes, be provided with in addition a plurality of to screw that should hole in fin, pass behind the hole of fan by screw again and lock the screw of fin, pass behind the hole of fan by screw again and lock the screw of fin, so that fan is fixed in fin.Yet, obviously relatively poor with the efficient of screw locking, in case and fan manufacturer change between its hole apart from the time, this fin promptly must go the screw that is drilled with relative position in addition again, has more increased the loaded down with trivial details of assembling operation with inconvenient.So the utility model is improved at the disappearance that above-mentioned conventional fan and fin are had on assembling.

The creation purpose

Main purpose of the present utility model is the retaining element by particular design at the composite set that a kind of fan and fin are provided, can be quickly and easily that fan and fin combination is fixing, and be convenient to dismounting.

A purpose more of the present utility model is at the composite set that a kind of fan and fin are provided, and it utilizes this protuberance to penetrate the set hole of fan by having protuberance and flexible retaining element, and utilizes elasticity that fan and fin are clamped and make up and fix.

Based on this, the composite set of fan provided by the utility model and fin is to include a fin, a fan and a retaining element, and this blower-casting is provided with a plurality of holes, and relative two ends of this fin are respectively equipped with a prominent plate; This retaining element is one-body molded a plurality of corresponding to the above-mentioned hole position and the protuberance that can penetrate for having with elastic wire, and make relative two ends of this elastic wire be formed with buckling parts, and relative two sides of each end are formed with the arc turn of bilge respectively, use this protuberance penetrated the hole of this fan after, again this arc turn of bilge is placed in this fin and gives the application of force and push, can make this buckling parts button be fixed in the set prominent plate of fin, and then fan and fin combination are fixed.

The utlity model has can make up quickly and easily fixing, and easy-to-dismount advantage.

Other purposes of the present utility model and function can be easier in understanding after conjunction with figs. and embodiment are further described.

The preferred embodiment explanation

As shown in Figure 1, the composite set of fan provided by the utility model and fin is to include a fin 3, a fan 2 and a retaining element 1; Wherein, this fin 3 is to be formed in the material with good heat transfer to have a plurality of radiating fins 31 on the plate body, and the outer end that is positioned at the radiating fin 31 of outermost two ends extends one respectively and is downward-sloping prominent plate 32.The housing of this fan 2 is to be provided with a plurality of holes 21.This retaining element 1 be with elastic wire one bending forming be have a plurality of corresponding to above-mentioned hole 21 positions and the protuberance 11 that can penetrate, and make relative two ends of this elastic wire be formed with buckling parts 12, and relative two sides of each end are formed with arc turn of bilge 13 respectively, use this protuberance 11 penetrated the hole 21 of this fan 2 after, again this arc turn of bilge 13 is placed in this fin 3 and gives the application of force and push, can make this buckling parts 12 buttons be fixed in the set prominent plate 32 of fin 3.

A wherein embodiment of retaining element 1 of the present utility model, be to be to have two extension rods 14 parallel to each other with spring steel wire one bending forming, and this two extension rod 14 respectively bending forming the protuberance 11 that is the U type is arranged, end by this extension rod 14 extends out curved arc turn of bilge 13 again, and the outstanding limit of its arc is towards the below, and is interconnected respectively and formed buckling parts 12 by two ends of this two arcs turn of bilge 13; Moreover, distance between this two extension rod 14 is the width less than said fans 2, so that this two extension rod 14 is cross-placed on this fan 2, and the width of this buckling parts 12 is prominent plate 32 width of being located at fin 3 greater than above-mentioned, is fixed in this prominent plate 32 (as shown in Figure 2) so that this buckling parts 12 detains.

Again as shown in Figure 3, another embodiment of retaining element 1 of the present utility model, be same as the structure shown in Figure 1 except having, it can form has cross one another a pair of extension rod 1A, and this two extension rod 1A respectively bending forming have towards below U-shaped protuberance 11, two ends by this two extension rod 1A extend out arc turn of bilge 13 respectively again, and are interconnected by the end of this arc turn of bilge 13 and form buckling parts 12; The position of this protuberance 11 is hole 21 positions corresponding to fan 2, make this protuberance 11 can penetrate hole 21 after, make its buckling parts 12 be fastened on the prominent plate 32 of fin again and fix.

And for example shown in Figure 4, the another embodiment of retaining element 1 of the present utility model, be to be made as two groups, and each group all forms the dovetail shape and has two free ends with spring steel wire, this two free end bending forming respectively goes out the protuberance 1B that can penetrate the hole 21 that is located at fan 2, and by the Breadth Maximum of this dovetail shape as for the solid buckling parts 12 of button at the prominent plate of fin, its two side then forms for elasticity and presses arc turn of bilge above fan 2.By above-mentioned structure, can easily fan 2 and fin 3 be combined, and can be easily with its dismounting, really for having much the creation of practicality and progressive.

The above only is in order to explain preferred embodiment of the present utility model, be not that attempt is done any pro forma restriction to the utility model according to this, so, all have relevant of the present utility model any equivalence of being done under identical creation spirit to modify or change, all must be included in the technical solutions of the utility model category.
