Description

The fastener assembly of CPU radiating fin

The utility model relates to a kind of fastener assembly of computer CPU heat radiator.

(Central Process Unit can produce high temperature hereinafter to be referred as CPU to the central processing unit of known computer when starting computing, 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, mainly be directly on CPU, to be provided with to have the heat radiator of a plurality of fins, and fan is set on heat radiator for the arithmetic speed heat abstractor design of CPU faster; The most heat that is produced during the CPU computing is absorbed by this heat radiator, and this CPU starts fan running simultaneously when computing and blow heat radiator so that heat is got rid of.

The mode that heat radiator is made up on CPU has multiple traditionally, wherein be used for being engaged in the heat radiator of more small-sized specification CPU, be that periphery at heat radiator is provided with a plurality of barbs, be provided with flange in the neighboring of CPU in addition, fix by the barb with heat radiator fastens the flange of CPU.Yet, be to be applicable to the design that directly CPU is inserted on the circuit board in the solid mode of barb mating flanges button, and the dimensions of this kind CPU is also less, needed radiator fan quantity also has only one.Yet, raising along with the CPU arithmetic speed, also along with strengthening (the above grade of PENTIUM II that for example present Intel company is produced), the heat that is produced during running is also bigger, so need more fan get rid of heat (generally being to utilize two fans) for its designed dimensions; And on heat radiator, during the fan of assembling more than two groups, each must be organized fan and cooperate one group of fastener to be fixed on one by one on the pedestal traditionally, again this pedestal is combined in heat radiator; But such array mode is cumbersome, and is inefficent, can influence production cost.Therefore, the utility model is improved at doing the existing shortcoming of assembling at the fastener that more combination of fans is needed during in heat radiator respectively each assembly is closed on the aforementioned conventional, make fastener when the main element of operating wherein, can reach the purpose that is fastened or removes fastening.

Fundamental purpose of the present utility model is providing a kind of fastener assembly of CPU radiating fin, makes a plurality of intermediate plates to be held on heat radiator during one bull stick by operation, or removes the clamping of intermediate plate to heat radiator, makes its loading and unloading more efficient.

Based on this, the fastener assembly of CPU radiating fin provided by the utility model, it includes a pedestal, a bull stick, a plurality of fairlead and intermediate plate; This pedestal is to be used for installing radiator fan; The shaft of this bull stick is provided with a plurality of projections; This intermediate plate is to form the ㄇ shape and have two pinches that are positioned at relative side, be provided with slotted eye on above its ㄇ shape, and its two pinch is respectively equipped with a side channel hole; This fairlead has a up vertically extending riser, and the upper end of this riser has a through hole, and has a guide feet respectively at the opposite end of this fairlead, and the inner side edge of this guide feet is to form hypotenuse; The riser of fairlead passes the last slotted eye of this intermediate plate, and this two guide feet is passed the side channel hole of intermediate plate, this bull stick passes the through hole of fairlead, and this bull stick is matched with the short slot of aforementioned pedestal, the prominent plate that allows this projection act on pedestal by rotating this bull stick rises to drive this fairlead, can make two pinches of this intermediate plate do holding action toward interior side direction simultaneously, make pinch be held on the relative both sides of heat radiator, also allow this two pinch be buckled in the default hole of CPU simultaneously.

Clearly, whether the utility model as long as the rotation of operation one bull stick can be controlled the clamping action of a plurality of intermediate plates simultaneously, is held on heat radiator with the decision intermediate plate when the loading and unloading heat radiator, and the more traditional structure of its packaging efficiency is high; And the control mode of utilizing bull stick to rotate in situ, can avoid interfering with the other electron component of main frame inside during heat radiator and causing damage in loading and unloading, whole assembling effect is also comparatively smooth, for having the creation of practicality and progressive.

Utilize structure provided by the utility model to realize that promptly can control a plurality of intermediate plates simultaneously by the rotation of operation one bull stick grips or remove clamping to heat radiator, the utmost point is suitable for the heat radiator that is engaged in relatively large CPU is done assembling.

Now conjunction with figs. is described in further details structure of the present utility model and function.
