Description

Fixer for heat radiator

[technical field]

The utility model relates to a kind of fixer for heat radiator, relates in particular to a kind of fixer for heat radiator with backboard.

[background technology]

The high-tech electronic industry has become the main flow on the market in recent years, along with the computing machine universalness, the processing of many data all must be dependent on computing machine and accurately finish rapidly, because the central processing unit chip module can produce high heat in the process of computing, for fear of the damage that causes assembly because of high thermal conductance, need usually heat is left.At present, mainly be to go out by heating radiator is closely contacted the high heat conduction that will be produced with the upper surface of central processing unit chip module.

General heat abstractor, extremely shown in Figure 2 as Fig. 1, comprise circuit board 200, heating radiator 300, latch 400, be used for the heat that central processing unit chip module 100 is produced is distributed, wherein central processing unit chip module 100 electrically connects with circuit board 200 mutually by electric connector 500, heating radiator 300 and central processing unit chip module 100 upper surfaces contact, heating radiator 300 is provided with latch 400, latch 400 directly is fixed together with circuit board 200 mutually by the through hole on the circuit board 200 201, thereby realizes that heating radiator 300 is connected with the stable of central processing unit chip module 100.

Yet the prior art defective is: when heating radiator is connected with the central processing unit chip module, latch 400 directly and circuit board 200 be interlocked, easily cause the circuit board bending, thereby influence the electric connection of chip module and circuit board.

Therefore, be necessary to design a kind of fixer for heat radiator of novel central processing unit, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of new radiator stationary installation, and it makes heating radiator can reach effective radiating effect, and can guarantee and chip module between electrically connect preferably.

In order to reach above-mentioned creation purpose, a kind of fixer for heat radiator of the utility model, it is used for heating radiator and circuit board are fixed, corresponding hole and the hole of being provided with of this heating radiator with circuit board, it is characterized in that: this fixer for heat radiator comprises latch and backboard, corresponding above-mentioned hole and hole are provided with accommodation hole on this backboard, and this latch can pass the hole of heating radiator, the hole of circuit board buckles in the accommodation hole of backboard.

Compared with prior art, the utility model fixer for heat radiator, because of it firmly establishes heating radiator on the chip module by the chimeric backboard that is fastened in of latch, the rigidity of intensifier circuit plate, avoid the circuit board bending, guarantee the electric connection preferably of chip module and circuit board, had better radiating effect simultaneously.

[embodiment]

Engaging the drawings and specific embodiments below is further described the utility model.

With reference to Fig. 3 and Fig. 4, a kind of fixer for heat radiator of the utility model, be used for the heat that central processing unit chip module 5 produces is left, comprise heating radiator 1, circuit board 2, latch 3 and backboard 4, wherein central processing unit chip module 5 electrically conducts mutually with circuit board 2.

Wherein, central processing unit chip module 5 is connected with circuit board 2 by electric connector 6, is positioned at the upside of circuit board 2.

Heating radiator 1 comprises base portion 10 and heat radiator 11, and wherein the upper surface of base portion 10 and chip module 5 contacts, and in addition, heating radiator 1 is provided with the hole of passing for latch 3, to realize being connected of heating radiator 1 and latch 3.

Corresponding latch 3 is provided with hole 20 on the circuit board 2, runs through the upper and lower surface 21,22 of circuit board 2.

Latch 3 comprises head 30, and from the head 30 downward main parts 31 that extend, the end of autonomous body 31 is formed with a cone shape barb 32, its central authorities are provided with a profile groove 33, wherein the upper width of barb 32 is greater than the width of main part 31, the head 30 of latch 3 can not pass the hole of heating radiator 1, and other parts can be passed the hole.

Backboard 4 is located at the lower surface 22 of circuit board 2, which is provided with protuberance 40 upwards, protuberance 40 be provided with accommodation hole 41 and with accommodation hole 41 perpendicular collude card division 42, accommodation hole 41 and collude between the card division 42 and to be the right angle, in addition, backboard 4 upper surfaces are provided with viscose glue 43, can be mutually bonding with circuit board 2.

When combination, at first, viscose glue 43 is arranged on backboard 4 tops, the application of force is located in the middle of the hole 20 of circuit board 2 its protuberance 40 tops, and it is rough contour to collude card division 42 and circuit board 3 lower surfaces 32, backboard 4 is fixed in the lower surface 22 of circuit board 2; Heating radiator 1 is seated on the upper surface of central processing unit chip module 5; Again latch 3 is seated in the hole of heating radiator 1 correspondence, the application of force is toward pressing down the accommodation hole 41 that the barb 32 that makes latch 3 passes corresponding backboard 4, chimeric again being fastened in colluded card division 42, because of latch accommodation hole 41 its internal diameters of the hole 20 of circuit board 2 and backboard 4 protuberances 40 maximum outside diameter less than barb 32, so profile groove 413 that the barb 412 of cylinder 411 ends is set, barb 32 can be divided into two and have the structure of elastic energy convergent-divergent, latch 3 can closely be combined heating radiator 1, circuit board 2 with backboard 4 fixing, to reach the effect of certain heat radiation.
