Abstract

The utility model relates to a fan mounting bracket for side mounting the fan on the radiator. The mounting bracket has a rectangular frame as the main part; a convex table is provided at each of the four corners to locate the fan. At the opposite sides of the main part a gripping arm is extended vertically to the main part to grasp the fan. A concave bending reverse hook is provided at the end of the gripping arm to fix the fan after being placed between the two gripping arms. At the position corresponding to the gripping arm of the opposite sides, another two hooks stretch toward the direction opposite to the gripping arm respectively; a reverse hook is equipped at the end of the hook. A convex block is equipped on the heat sink of the radiator corresponding to the two hooks of the main part of the fan mounting bracket. Mounting can be conducted by wedging the hook of fan mounting bracket into the heat sink, and glide and stop on the convex block.

Description

Fan Fixture

[technical field]

The utility model is about a kind of fan Fixture, is meant a kind of easy accessibility, side-mounted fan Fixture efficiently especially.

[background technique]

Flourishing fast development along with computer industry, the motion speed of electronic component is more and more faster, the high-frequency high-speed processor is constantly released, but the heat that the high-frequency high-speed operation produces electronic component also increases sharply thereupon, further make the computer-internal temperature more and more higher, the stability and the performance of central processing unit (CPU) operation in serious threat, for guaranteeing that central processing unit (CPU) can normally move, must discharge the heat that it produced in time, fast, for this reason, industry installs a radiator additional on the central processing unit (CPU) surface usually, with the heat of timely its generation of discharge.Simultaneously, in order to guarantee the high efficiency of radiator heat-dissipation, on radiator, install a fan in addition additional to assist heat radiation, mounted fan can play promoting effect to the exchange of computer system air-flow on the radiator and many occasions are in order to make, fan side need be contained on the radiator, thereby make its air-flow that blows through behind radiator again order and impel that air is discharged to the cabinet outside fast in the system through other chip.

In the prior art, mostly the direct screw lock of mounting hole that passes four jiaos of fan frames by screw on radiating fin, but this means of fixation is very easy to make radiating fin to produce distortion and sliding the mistake, causes the disengaging of radiator and fan.It is the intensity of strengthening being screwed into radiating fin behind the screw that the dealer is arranged, the strong construction that makes itself and radiating fin formation one can provide fan to fix on the radiator is provided the metal lamellar body of given shape, again with the fan screw lock on this fixed structure, this mode, installation reliability no doubt can reach requirement, but whole assembling process complexity, need earlier the metal lamellar body to be combined on the radiator, again with the fan screw lock on it, and dismounting is trouble too, now is easy to assembly, fast become the new demand that the dealer assembles computer, the said fans means of fixation is unequal to using gradually, therefore need a kind of can the convenience of design, the fan Fixture of dismounting fan quickly is to adapt to the requirement of industry development.

[summary of the invention]

The purpose of this utility model is to provide a kind of fan Fixture, is meant a kind of easy to assembly, side-mounted fan Fixture efficiently especially.

The purpose of this utility model realizes by following technical proposal:

The utility model fan Fixture is in order to be contained in fan side auxiliary heat dissipation on the radiator, and it comprises a smooth shaped as frame main part, and its middle part has an opening; At least two holding limbs, at least one opposite side vertical extent of autonomous respectively body and going out; Two hook sheets, an opposite side of autonomous body goes out to the direction vertical extent opposite with holding limb respectively, and its end is provided with barb, can match with the radiating fin of radiator and the fan Fixture side is contained on the radiator.

The utility model fan Fixture utilizes the elasticity of two holding limbs to come the clamping fan and realize fixing by means of hook sheet and radiating fin interaction, in conjunction with easily and fast, only need two hook sheets of this fan Fixture one side to be wedged the gap of radiating fin and take advantage of a situation to glide and easily to realize installing, and when dismounting, only need instead will definitely fan Fixture to extract and get final product, easy accessibility, fast.

[description of drawings]

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

Fig. 1 is the three-dimensional exploded view of the utility model fan Fixture and fan and radiator.

Fig. 2 is the partial sectional view of the utility model fan Fixture and fan and radiator combination.

[embodiment]

See also Fig. 1, the utility model fan Fixture 10 is in order to be contained in fan 20 sides on the radiator 30.This fan 20 has a framework 22, and this framework 22 is provided with exhaust outlet 24, and four corners have a mounting hole 23 respectively; This radiator 30 has a pedestal 32 and by these pedestal 32 upwardly extending some radiating fins 34, is provided with a plurality of grooves 36 perpendicular to radiating fin 34, and wherein two radiating fins are provided with projection 35.

This fan Fixture 10 tools one rectangular frame main part 12, its central authorities be provided with fan 20 frameworks 22 on exhaust outlet 24 corresponding openings 13, so that the air communication that fan 20 blows is crossed and is blown on the radiator 30, these main part 12 4 corners respectively are provided with a boss 14, can be when fan 20 be installed on the main part 12 stopper in the mounting hole 23 of fan 20 frameworks 22, be beneficial to the location of fan 20 on this main part 12, one opposite side outer rim of this main part 12 is respectively extended a holding limb 16 in order to clamping fan 20 perpendicular to main part 12, these holding limb 16 ends are provided with barb 17 curved in, it is fixing that fan 20 is inserted behind 16 of two holding limbs, one opposite side of this main part 12 extends two hook sheets 18 to the direction opposite with holding limb 16 respectively, these two hooks sheet, 18 ends are established barb 19 to excurvation, this barb 19 hooks together the lateral margin that is positioned at groove 36 1 sides at radiating fin 34, and wherein the spacing of this two hooks sheet 18 is slightly larger than the spacing of two projections 35 on the radiating fin 34.

Please consult Fig. 2 simultaneously, during assembling, fan 20 is pressed between two holding limbs 16 on the fan Fixture 10 rectangular frame main parts 12, and boss 14 stoppers that make main part 12 4 corners are in the mounting hole 23 of 22 4 jiaos of fan 20 frameworks, and then fan 20 firmly and closely combines with fan Fixture 10 under the acting in conjunction of main part 12 and boss 14, holding limb 16 and barb 17.Vertically control the combination of this fan Fixture 10 and fan 20, side leans against a side of radiator 30, and with two hook sheets, 19 wedging radiating fins, 34 gaps, and the barb 19 of its end hooks together the lateral margin that is positioned at groove 36 1 sides at radiating fin 34, this fan Fixture 10 is glided along radiator 30 sides, on the projection 35 of its hook sheet 18 blocks at radiating fin 34, because the barb 19 of hook sheet 18 ends hooks together radiating fin 34 lateral margins, and this hook sheet 18 and 34 of radiating fins have drive fit (spacing of two hook sheets 18 is slightly larger than the spacing of two projections 35 on the radiating fin 34), thereby the combination of fan 20 and fan Fixture 10 can upwards not reach the side direction escape, and because of the block effect of radiating fin 34 upper protruding blocks 35 can prevent to glide, thereby the firm combination of fan Fixture 10 and fan 20 is positioned at the side of radiator 30.
