Description

The stator of radiator

Technical field

The utility model relates to a kind of stator of radiator, in particular, the utility model relate to a kind of do not need to harden with machine close, and do not need the machine board mold is made an amendment, and meet the stator of radiator of the central processing unit of different size.

Background technology

CPU (CPU, Central Processing Unit) is indispensable main parts in the middle of the computer system, be mainly used to do sums, logical operation, and the implication of explaining each instruction, and most parts in the control computer system.

Because the lifting of scientific research technical capability, the execution speed of CPU is more and more faster, therefore CPU must possess good heat radiation accordingly, just be unlikely to when moving over a long time, because overheated and produce the situation that usefulness reduces, even have influence on the useful life of CPU itself.The general practice is directly to fixedly install a fan or at the CPU heating face metal heat sink (being generally aluminium matter or copper) of fitting on CPU, because the material of radiator has good heat conductivity, so seeing through it contacts with the direct of CPU surface, just can the thermal energy transfer that CPU produced is extremely outside, and allow CPU maintain between certain temperature range, to keep its normal operation.

Above-mentioned radiator is a kind of a kind of structure that is attached on the CPU, and in order to reach fixing effect, once adopted the mode of using jelly to bind to fix in the past, but the heat-conducting effect of glue material is relatively poor, the heat energy that is difficult to CPU is sent is passed to radiator effectively, so seriously influence the effect of heat radiation, and colloid has lower fusing point, when running into high temperature, colloid can produce the thawing phenomenon, can't keep good fixed relationship thereby make between radiator and the CPU.

In addition, also once adopted the mode that fastener is interlocked radiator and CPU, but under this mode, because of can not intercepting radiator, fastener itself do not contact with the surface of CPU, and fastener also more adopts metal or heat resistant plastice to make, therefore must be good than the gummed mode on effect.

In addition, more have radiator, can more firmly make the good fixed relationship of maintenance between radiator and the CPU with lock mode on the machine plate of the circuit board that is provided with central processing unit.But when it is assembled, need use stator, please refer to the schematic diagram that stereogram under the existing stator two different visual angles shown in Figure 1A, Figure 1B and existing stator shown in Figure 2 and circuit board, radiator and machine harden and close.This stator 50 in the form of sheets, and have elasticity pinch 51, the perforation 52 and the insulation shell fragment 53.In when assembling, opening 81, and the perforation 52 of stator 50 that must make sealed post 61 pass perforate 71, the circuit board 80 of radiator 70 in regular turn, again with screw 62 spiral shells in sealed post 61, and be arranged in machine plate 90.At this moment, elasticity pinch 51 can pass opening 81, and is folded in opening 81 edges, and the insulation shell fragment 53 can be butted on circuit board 80 bottoms, with the buffering radiator 70 compacting strength.Certainly because this kind design, so machine plate 90 must offer screw 91 or have the projection of screw, to do above-mentioned assembling.But when this kind design was applied to the central processing unit 82 of different size, but screw 91 or the projection that machine plate 90 is offered was positioned at different positions, so will bring puzzlement to assembling.

Summary of the invention

The utility model has overcome deficiency of the prior art, provide a kind of under the different situation of central processing unit size, need not radiator and machine and harden and close, and need not the ancillary cost cost and the time is revised machine board mold, the just stator that radiator is combined with circuit board.

For achieving the above object, the stator of radiator provided by the utility model comprises a sheet body and one by locking holes, and corresponding to lock-in component and opening, its split shed is to be located on the circuit board and corresponding to lock-in component by locking holes for this.The stator of described radiator makes lock-in component pass opening and by locking holes, and in conjunction with radiator, circuit board and sheet noumenon, allows described radiator firmly contact central processing unit, thereby looses the heat of central processing unit of overflowing.The utility model is applicable to the radiator with lock-in component and has fixing between the circuit board of central processing unit.

Compared to prior art, the utility model does not need to make radiator to be locked on the machine plate, and the machine plate also need not additionally be offered screw or projection etc. again, therefore made the perforate of the radiator that these screws or projection correspond to and the opening of circuit board in the past, and the design that meets the different size central processing unit, also just no longer need.Thereby the utility model do not needing ancillary cost cost and time to remove to revise the machine board mold, and radiator is combined with circuit board, and radiator do not need to harden with machine and close, thereby improves the collocation degree between circuit board and machine plate.

Embodiment

The schematic diagram that the utility model shown in Fig. 4 C combines with circuit board and radiator, stator according to radiator provided by the utility model, can allow radiator 10 be fixed on the circuit board 20, the central processing unit 21 of while circuit board 20 can contact with radiator 10, uses so that the heat that central processing unit 21 is produced when running looses excessive.

As shown in Figure 3A be exploded view of the present utility model, and the constitutional diagram of the present utility model shown in Fig. 3 B, the stator of radiator provided by the utility model is to be applied in fixing between radiator 10 that is provided with lock-in component 11 and the circuit board 20 with central processing unit 21, and offers the opening 22 corresponding to lock-in component 11 on circuit board 20.This lock-in component 11 comprises sealed post 111, screw 112 and elastic parts 113, and screw 112 is arranged in sealed post 111 movably, and elastic parts 113 is arranged between sealed post 111 and the screw 112, in order to the sealed strength of buffering screw 112.

The stator of radiator provided by the utility model comprises a sheet body 30, this sheet noumenon 30 includes first plate 31 and second plate 32, wherein first plate 31 and second plate 32 are to be mutual applying, and when combining with circuit board 20 and radiator 10, first plate 31 can touch circuit board 20.

First plate 31 is provided with Buffer Unit 311, elasticity pinch 312, shell fragment 313 and insulation assembly 314, and also offers hole 315.Buffer Unit 311 is arranged at first plate 31 (certainly among the figure Buffer Unit 311 are the tops that are arranged at insulation assembly 314) as can be known, in order to when first plate, the 31 contact circuit plates 20, and the compacting strength of buffering radiator 10.The material of Buffer Unit 311 can be rubber.Elasticity pinch 312 is convexly set in first plate 31, and corresponding to opening 22, to be folded in opening 22 edges.Shell fragment 313 is convexly set in first plate 31, and its surface is provided with insulation assembly 314, with when first plate, the 31 contact circuit plates 20, makes shell fragment 313 across insulation assembly 314 contact circuit plates 20, and the compacting strength of buffering radiator 10.Certainly, insulation assembly 314 also can be arranged on other surface of first plate 31 except can being arranged at shell fragment 313 surfaces, in order to when first plate 31 touches circuit board 20, avoid and the part of circuit board 20 between the situation of conducting takes place.

And second plate 32 convexes with the lock 321 that is arranged in hole 315, and flange 322, and wherein lock 321 offers by locking holes 3211, is to can be screw by locking holes 3211, and corresponding to lock-in component 11 and opening 22.Flange 322 is convexly set in the edge of second plate 32, and first plate 31 is arranged in the flange 322 of second plate 32.
