Description

The heat abstractor buckling device

The utility model relates to a kind of heat abstractor buckling device.

Because the speed that computer cpu (CPU) is carried out is faster, it is also higher that it produces corresponding heat, if fail the heat of CPU is spread rapidly, will influence the stability of computation.Therefore, generally all install a heat abstractor additional on CPU, the high temperature that makes CPU produce can be led thermal source shedding by heat abstractor.Former times, heating radiator 10 penetrated the pilot hole 21 of CPU pedestal 20 via dowel 12, blocks dowel 12 by clip sheet 30 again, makes the base plate 11 of heating radiator 10 closely push down CPU22 and combination with heat abstractor as shown in Figure 1.The structure of right known clip sheet as shown in Figure 1, is to establish stopper slot 31 in clip sheet two outer concave, and fastens with buckle mode and dowel 12, and its quality is difficult to control, often bumps the crowded situation that gets loose because of neglecting not fastening or external force.Other has a kind of framework 40 as shown in Figure 2, this framework 40 is provided with the plate 42 that spreads out can ccontaining CPU60, its two opposite side respectively is provided with two coaks 41, pillow 411 is buckled in order to chimeric CPU60 in coak 41 lower ends and being provided with, heat sink 50 also utilizes its block 51 with the upper surface of buckle in CPU60 simultaneously, be in regular turn with heat sink 50 during assembling, framework 40 successively is entrenched in the upper surface of CPU60, right this kind is with the comparatively inconvenience of the structure application of force of the folded formula of sandwich bag, because of its two opposite side respectively is provided with two coaks 41, need firmly push nested with two hand appropriateness during assembling, also need during dismounting to pull open button pillow 411 with thumb and forefinger, heat sink 50 is ejected and injured, even the collision have influence on other computer componentses, very undesirable.

This creator is because the various shortcomings of known heat abstractor in the design of fastening structure, and cause the many bad of practicality and fit on, at the method for the various solutions of the concentrated research of shortcoming such as above-mentioned,, create a kind of heat abstractor buckling device finally through after continuous research and the improvement.

Shortcoming at the prior art existence, fundamental purpose of the present utility model is to provide a kind of heat abstractor buckling device, this buckling device includes a heating radiator and a frame type button, this heating radiator is equipped with a scapulet outside a side direction of base, the length of this scapulet is smaller than the contraposition bar, can insert to be embedded in contraposition bar lower end; This frame type button one side is established the contraposition bar, cramp is received and the frame height in below, contraposition bar two ends, its offside is provided with lean against part, a catch is established in the lean against part lower end, the upper end is provided with towards outer arc turns over and rubber-like button plectrum, respectively establish deckle board in other two relative edges, this deckle board is narrower and small and be connected to form the opening of a broad with cramp near an end of contraposition bar, and there is fin deckle board lateral folding down, therefore can form, following two storage tanks, following storage tank can cooperate the fit location of the chute of central processing unit plate body, and the high space that forms of contraposition bridge just can hold the scapulet of embedding heat radiator, makes other end of heat radiator gently withhold elasticity button plectrum downwards and can be placed in storage tank.During combination, opening under the first artoregistration bar from outside to inside of central processing unit is inserted in down storage tank, make its panel place the deckle board upper end, the scapulet of heating radiator is after hook is embedded in contraposition bar below from inside to outside again, then heating radiator is held in addition to pressing down,, be about to central processing unit simultaneously and tightly suppress and unlikely coming off in last storage tank with jostle button plectrum and buckle.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of heat abstractor buckling device, mainly comprise a heating radiator and a frame type button, it is characterized in that: heating radiator is established a scapulet in a side direction evagination of its base, and the length of this scapulet is smaller than the contraposition bar; Frame type button one side is made as the contraposition bar, " L " type cramp is respectively received in this below, contraposition bar two ends, be formed with the scapulet that a space holds the embedding heating radiator, its offside is provided with lean against part, a catch is established in this lean against part lower end, the upper end is provided with the elasticity button plectrum that turns over towards outer arc, then respectively be made as deckle board in other two opposite sides, this deckle board is narrower and small and connect into a broad opening with " L " shape cramp near an end of contraposition bar, and this deckle board lateral folding down has fin to become upper and lower two storage tanks, following storage tank is nested with central processing unit, last storage tank buckle heating radiator.

By a kind of heat abstractor buckling device of the utility model, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation; The utility model can be simple and easy, rapidly in conjunction with heating radiator and central processing unit.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
