Description
[Ji Intraoperative field]
The utility model relates to a kind of fixed structure of radiating module, particularly is applicable to the fixed structure that radiating module utilizes the clasp of grab and circuit board to be interlocked.
[Bei Jing Ji Intraoperative]
High speed development along with computer and information technology, the integrated level of computer chip is more and more higher, the integrated of various electronic devices and components also constantly strengthens, therefore its heat dissipation problem is also more and more outstanding, if the heat of electronic circuit can not get getting rid of timely and effectively (i.e. heat radiation), electronic component can not steady operation even can be burnt.Therefore various heat dissipation equipments meet the tendency and lead, its normally with a thermal conductivity preferably cooling base be close to heater element, and this cooling base deviates from the one side of heater element and extends a plurality of fin, and other position of the top of this fin or electronic installation is fixed a fan again, utilize modes such as heat conduction, cross-ventilation to be electronic element radiating.
The key factor of radiating effect that directly influences the heat abstractor of said structure has 2 points: the one, and the tightness degree that contacts of cooling base and heater element, the 2nd, the size of fin area.
Though it is very smooth smooth that the surface of cooling base and heater element seems, can see that at microscopically there is millions of micropores on the surface.Because the existence of heater element surface micropore, real contact has only wherein some points on two surfaces of being close to.According to the data introduction, general contact area only accounts for about 20%, and other place then is full of by air.General knowledge is told us the copper as fin material, aluminium has heat conductivility preferably, and air is the very poor material of a kind of thermal conductivity (20 ℃ time conductive coefficient be about 0.024W/mK), and conductive coefficient is about 1/8333 of aluminium.Although therefore cooling base has good heat-conducting, because between electronic component and cooling base is not that the face of being expected contacts, but some contact, promptly as between the surface of heater element and the cooling base by air separated, thereby its contact heat resistance is very big, and air becomes the obstacle that conducts heat between electronic component and the cooling base.
In order to solve " contact " problem, conventional method is to be coated with the last layer heat-conducting medium between cooling base and heater element, utilize the contact area of heat-conducting medium blind, increase thermal source and cooling base, the heat output that reduces the hot-fluid distance, increases, to increase combining between cooling base and heater element, improve the defective of " some contact ", increase the contact-making surface that cooling base and heater element are asked like this, played thermolysis preferably.For this reason, industry normally is provided with a fastener 31 (as shown in Figure 1) on cooling base 30, and correspondence is provided with clasp 42 on the circuit board 4 of corresponding installation heater element 41, utilize fastener 31 and clasp 42 to be interlocked and impose on the enough pressure of cooling base 30, thereby make cooling base 30 contact fully with heater element 41.
Area at the fin of cooling base 30, industry realizes by the number or the height that increase fin 33 mostly, for fin 33 number aspects, because of the realization difficulty of machining aspect is difficult for increasing, then can utilize case of electronic device (not shown) volume inside for the height aspect as far as possible, thereby may allow the height of fin 33 differ, as shown in Figure 1, for reducing electronic installation whole height (or thickness), the memory bar 40 (or interface card) of electronic installation circuit board 4 relatively is obliquely installed, the height of the fin 33 that so is adjacent just can not be too high, damage to prevent the two from colliding, relatively then can be higher relatively away from the height of the fin 33 of this memory bar 40, to increase the area of dissipation of fin 33, at the asymmetrical cooling base 30 of this kind, utilize 31 problems that cooling base 30 installation direction mistakes may occur of existing fastener, specifically can be analyzed as follows: as shown in Figure 1 in conjunction with Fig. 1, folder is established fastener 31 between existing cooling base 30 two fin 33 in the middle, two ends of this fastener 31 protrude these cooling base 30 lateral margins and are extended with elastic arm 34, and two elastic arms, 34 ends are provided with grab 32, this grab 32 is vertically to bend from the support or oppose direction of discrete heat pedestal 30 of the end of this elastic arm 34, on corresponding this circuit board 4 to should grab 32 correspondences being provided with clasp 42, this two clasp 42 is located at cooling base 30 both sides respectively and is parallel to each other, and its bearing of trend is vertical with the bearing of trend of corresponding grab 32, so pass through the grab 32 of two elastic arms 34 and corresponding clasp 42 buckles, thereby cooling base 30 is mounted on the top of heater element 41, and pedestal 30 surfaces that guarantee to loose closely attach with heater element 41 surfaces, because of the described fastener 31 of said structure and clasp 42 all are symmetrical arranged, fin 33 as cooling base 30 also is symmetrical arranged, then no matter where to equal no problem is installed, if but fin 33 asymmetric settings, then might install by mode shown in Figure 2, this moment is highly higher because of the fin 33 of contiguous memory bar 40, therefore may be in transportation or installation process, this fin 33 collide with memory bar 40 and may damage memory bar 40 or influence memory bar 40 and circuit board 4 between electric connection.
