[background technology]

Along with the computerized information industry develops rapidly, the arithmetic speed of all kinds of electronic components is more and more faster, and the heat that it produced is also more and more, and if too much heat can't in time be discharged, the stability when having a strong impact on the electronic component operation.For this reason, industry is installed the heat abstractor of an aluminium extruded type fin and combination of fans usually at the electronic component end face, to assist to discharge heat.

Existing heat abstractor comprises a fan 1 and a radiator 3 as shown in Figure 1.1 four jiaos of ends of this fan are respectively equipped with a fixing hole 2, this radiator 3 comprises a pedestal 4 and the radiating fin 5 some parallel to each other that is arranged on this pedestal 4, attack respectively between two radiating fins 5 in these radiator 3 outsides and be provided with screw thread 6, pass the fixing hole 2 of this fan 1 and lock mutually by screw 7, and this fan 1 is fixed on this radiator 3 with screw thread 6 on this radiating fin 5.But this heat abstractor is fixed on this fan 1 on this radiator 3 by screw 7, needs by other instrument when dismounting, and dismounting is loaded down with trivial details, and very easily damages other parts of computer-internal.In addition, the radiating fin 5 of this radiator 3 deforms under the extruding of screw 7 easily, thereby the stripped thread phenomenon takes place, and makes this fan 1 have fixing unstable doubt.

[summary of the invention]

The purpose of this utility model is to provide a kind of fastening fan firmly and easy accessibility, labour-saving heat abstractor.

The purpose of this utility model is achieved through the following technical solutions: the utility model heat abstractor comprises a radiator, plurality of fixed part, plurality of fixed axle and a fan.Wherein, this radiator has a pedestal, and this pedestal upwards extends some radiating fins parallel to each other, these pedestal two ends extend upward respectively and form a sidewall, each sidewall extends upward and forms a projection, and this projection outside is provided with a groove, and the projection both sides are offered a breach respectively.Each fixture all has a main part, and these main part both sides outwards bend respectively and extend a connecting piece, all run through on each brace and offer a pivoted hole; This main part upper end bends inwards and extends one and compress sheet; This main part lower end bends inwards and extends a snap-latch piece.Each fixed axis passes the pivoted hole of corresponding fixture and is contained in the groove of radiator sidewall and this fixture is connected on this radiator.Four jiaos of ends of this fan are respectively equipped with a perforation, the snap-latch piece by each fixture and compress sheet and be pressed on four jiaos of ends of this fan and this fan is fixed on this radiator.

Compared with prior art, the utility model heat abstractor has and fastens fan firmly and easy accessibility, labour-saving advantage.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is further described.

[embodiment]

Please consult Fig. 2 and Fig. 3 together, the utility model heat abstractor comprises a radiator 10, plurality of fixed part 30, plurality of fixed axle 50 and a fan 70.

This radiator 10 has a pedestal 11, this pedestal 11 upwards extends some radiating fins parallel to each other 13, these pedestal 11 two ends extend upward respectively and form a sidewall 15, each sidewall 15 further extends upward and forms a projection 17, these projection 17 outsides are provided with a groove 19, and these projection 17 both sides are then offered a breach 21 respectively.

Each fixture 30 is all formed by the elastic material integrated punching, each fixture 30 has a main part 31, these main part 31 both sides respectively outwards bending extend a connecting piece 33, each brace 33 extends a retaining piece 35 downwards, and runs through on the brace 33 and offer a pivoted hole 37; These main part 31 upper ends bend inwards and extend one and compress sheet 39, and this further outwards and upwards extend a pressing tablet 41 compresses sheet 39, with the foundation as the application of force; These main part 31 lower ends bend inwards and extend a snap-latch piece 43, and punching press forms a stator 45 on these snap-latch piece 43 mediads, uses during for secure fit.

Each fixed axis 50 passes the pivoted hole 37 of corresponding fixture 30 and is contained in the groove 19 of these radiator 10 sidewalls 15, thereby plurality of fixed part 30 is connected on this radiator 10.

The stator 45 of four jiaos of corresponding plurality of fixed parts 30 of this fan 70 is respectively equipped with a perforation 72.

During assembling, in advance each fixture 30 correspondence is positioned in the breach 21 of these radiator 10 pedestals 11 sidewalls 15, again each fixed axis 50 is passed successively the groove 19 of these radiator 10 pedestals 11 and the pivoted hole 37 of respective fixation part 30, so that each fixture 30 is connected on this radiator 10; Then, the groove 19 that will be equipped with the radiator 10 of plurality of fixed axle 50 with anchor clamps (figure does not show) clamps, to prevent that plurality of fixed axle 50 from coming off, simultaneously the retaining piece 35 of each fixture 30 is pressed on the sidewall 15 of this radiator 10 and makes each fixture 30 slightly outward-dipping, then, this fan 70 is inserted in the plurality of fixed part 30 and is firmly pressed down this fan 70 from top to bottom, thereby the stator 45 that makes each fixture 30 is fastened in the perforation 72 of 70 4 jiaos of ends of this fan, preventing fan 70 horizontal slips, and the sheet 39 that compresses of each fixture 30 is pressed on these fan 70 end faces, four corners respectively and this fan 70 is fixed on this radiator 10.

During dismounting, pin the pressing tablet 41 of each fixture 30 upper end also firmly outwards breaks off with the fingers and thumb with hand, the retaining piece 35 of each fixture 30 is pressed on the sidewall 15 at these radiator 10 two ends, and the snap-latch piece 43 of each fixture 30 lower end holds up this fan 70, takes out this fan 70 and gets final product.
