Description
The utility model relates to a kind of central processing unit heat abstractor, refers to that especially a kind of flow resistance is little, and air velocity is accelerated, and effectively increases heat dissipation capacity, the heat abstractor that radiating effect is preferable.
The fins group of existing heat abstractor mostly is aluminium extruded type or die-casting die, and the flow resistance of aluminium extruded type fins group is bigger, and circulation of air is slower, can't effectively increase heat dissipation capacity, and the interval of its fin, highly, thickness be difficult for to adjust, and can't reach preferable radiating effect; The flow resistance of die-casting die fins group is less, but its fin length breadth ratio etc. are subjected to suitable restriction, the interval of fin, highly, the thickness adjustment is difficult for, and still can't reach preferable radiating effect; Therefore, existing central processing unit heat abstractor has the shortcoming of radiating effect difference.
Fundamental purpose of the present utility model is to provide a kind of central processing unit heat abstractor, and it includes fan, current limliting cover, fins group and heat transfer base plate; Adopt the high density structure dress that volume is little, flow resistance is little, its current limliting cover is accelerated air velocity, effectively increases heat dissipation capacity, utilizes its two direction current limlitings, and the characteristics of two direction discharge airflows are accelerated heat interchange; The continuous crape folding fin of fins group or the interval of pin fins, highly, thickness is adjusted easily, reaches preferable radiating effect.
The purpose of this utility model is achieved in that a kind of central processing unit heat abstractor, it includes fan, current limliting cover, fins group and heat transfer base plate, the current limliting cover is a hollow form cover body, be shaped in the fan bottom, the current limliting cover has extended to form adjutage downwards at two relative sidewalls at least, and two adjutage bottoms are provided with fastener; Fins group forming metal thin slice is continuous crape folding fin, and fins group is provided with profile groove, and fan and current limliting cover are placed on this fins group top, and current limliting cover sidewall is around fins group; Have on the heat transfer base plate and the corresponding fastener of current limliting cover adjutage bottom fastener, current limliting cover adjutage engages one by the bottom fastener with the fastener of heat transfer base plate, fan and current limliting cover and heat transfer plate integrally combine, and fins group is fixed between fan, current limliting cover and the heat transfer base plate.
Fan and current limliting cover can be separate type design, and fan and current limliting cover are two independent individualities of recombinant after the separate machined; Its fins group is the pin fins with the sheet metal moulding; Can directly go out convex body on the fins group, between convex body and the fins group holes be arranged, this convex body and holes are used for replacing profile groove.
The utility model is rational in infrastructure, has improved the shortcoming of existing central processing unit heat abstractor, and air velocity is very fast, has improved heat-sinking capability, the interval of fin, highly, thickness adjusts easily, radiating effect is better.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model three-dimensional combination figure.
Fig. 2 is the utility model three-dimensional exploded view.
Fig. 3 is the utility model floor map.
Fig. 4 is another embodiment floor map of the utility model.
Fig. 5 is the three-dimensional exploded view of the another embodiment of the utility model.
Fig. 6 is the utility model three-dimensional exploded view of an embodiment again.
As Fig. 1, Fig. 2 and shown in Figure 3, be the utility model one embodiment, include a fan 10, a current limliting cover 11, a fins group 12 and a heat transfer base plate 13; Wherein fan 10 4 avris walls extend to form integrated current limliting cover 11 downwards, current limliting cover 11 is one-body molded in fan 10 bottoms, it is a hollow form cover body, current limliting cover 11 sidewall length can adjust as required, to obtain maximum air efflux velocity, current limliting cover 11 extends to form adjutage 14, two adjutages 14 bottoms downwards fastener 15 is arranged to being less than relative two sidewalls.
Fins group 12 is by the sheet metal moulding, form continuous crape folding fin or pin fins, on this fins group 12 suitable profile groove 16 is arranged, fan 10 and current limliting cover 11 place fins group 12 tops, suitably around fins group 12, the fin of fins group 12 can effectively reduce windage to current limliting cover 11 sidewalls, and thermal efficiency height, with thin slice moulding thin or suitable thickness, fin density can be higher.
The good material of heat transfer base plate 13 usefulness thermal conductivity is made, its side has the adjutage 14 bottom fasteners 15 corresponding fasteners 17 with current limliting cover 11, the adjutage 14 of current limliting cover 11 utilizes bottom fastener 15 to engage with heat transfer base plate 13 side fasteners 17, make fan 10 and current limliting cover 11 and 13 suitable the integrally combining of heat transfer base plate, and fins group 12 is fixed in fan 10, between current limliting cover 11 and the heat transfer base plate 13, wait in addition to engage, more than constitute the utility model central processing unit heat abstractor at fins group 12 and 13 available heat-conducting glues of heat transfer base plate.
A kind of central processing unit heat abstractor that the utility model provides can utilize heat transfer base plate 13 suitably to be combined in central processing unit (CPU) top (not shown), to assist the central processing unit heat radiation; The utility model is adorned with mining height density structure, and volume is little, and flow resistance is little, and current limliting cover 11 can form the space of a constraint air-flow trend; And current limliting cover 11 covers long (L or L1 etc.) can be done suitably to adjust according to fin density, to obtain best radiating efficiency; Also can adjust discharge area, and then reach the effect of adjusting wind speed, current limliting cover 11 can make air velocity accelerate, and can effectively increase heat dissipation capacity; And current limliting cover 11 sidewall length can adjust according to need, can be designed to asymmetric (monolateral or bilateral or three side sealing closes), make it the trend of adjustable heat exchange back hot blast, can form two direction current limlitings.Two directions are discharged airflow, and heat interchange is preferable; Again since continuously crape folding fin or pin fins be folded to form by sheet metal, but not aluminium extruded type or die cast, therefore, can select proper spacing, highly, thickness, the restriction of manufacture process is less, fin at interval, highly, the thickness adjustment is easy, thereby reach better radiating effect; Fan 10 utilizes fastener 15,17 and heat transfer base plate 13 to be combined into one, and can not use extra fan fastener.
As shown in Figure 4, the utility model can be with fan 10 and current limliting cover 11 separate design, fan 10 and current limliting cover 11 are two independent individualities, again fan 10 is installed in current limliting cover 11 inside after the separate machined, fan 10 utilizes keeper 18 location on current limliting cover 11 tops, is convenient to the existing fan of current limliting cover 11 collocation and uses.
As shown in Figure 5,, on fins group 12, can directly dash and adorn suitable convex body 19, be formed with holes 20 between convex body 19 and the fins group 12, replace profile groove 16 with this convex body 19 and holes 20 for the another embodiment of the utility model.
As shown in Figure 6, be the another embodiment of the utility model, the put direction and the profile groove 16 etc. of fins group 12 can be changed according to need, heat transfer base plate 13 side fasteners 17 can be made corresponding changes.
