Embodiment
Fig. 1,2 shows the preferred example of a heat abstractor 1 of the present invention.As shown in Figure 1, said heat abstractor 1 is to carry on a circuit board 6, and comprises a fan housing 2, a radiator 3, one first fan 4 and one second fan 5, wherein:
Said fan housing 2 includes one first through hole 222 and one second through hole 224 that longitudinal separation is arranged.
Said radiator 3 is provided in a side of in the said fan housing 2, and comprises multi-disc lateral separation fin 30 side by side.
Said first fan 4 be provided in a side of on the said fan housing 2 and the position in first through hole 222 of said fan housing 2, said second fan 5 be provided in a side of on the said fan housing 2 and the position in second through hole 224 of said fan housing 2.Said first fan 4 all is to blow to said radiator 3 with the wind that said second fan 5 is produced.
Wherein, said fan housing 2 mainly is to be used for fixing said first, second fan 4,5, and in practical application, the mode that also can adopt support to hang is fixed on first, second fan 4,5 on the said radiator 3.
As shown in Figure 2; One heat source-contacting surface 31 is arranged at the bottom of said radiator 3; Said heat source-contacting surface 31 is to be used for abutting on the heat-conducting plate 60 (for example copper soleplate); 60 of said heat-conducting plates abut in the thermal source 61 on the said circuit board 6, and the heat energy of said thermal source 61 is promptly led on the said radiator 3.In this example, said circuit board 6 is computer display cards, and said thermal source 61 is meant the GPU of position on said computer display card.In addition, the heat source-contacting surface 31 of said radiator 3 also can directly abut on the said thermal source 61.
Specifically, can see obviously that in Fig. 2 said first fan 4 all is arranged to be obliquely installed with said second fan 5, make them for the heat source-contacting surface 31 of said radiator 3, all be obliquely installed, and their incline direction also is identical.So, the wind-force that said first fan 4 blows to mid portion 7 blows to the wind-force of mid portion 7 greater than said second fan 5, has eliminated the stagnant wind district that known technology has.The wind that this expression blows out from said first fan 4 must have the middle part 7 of some said radiators 3 of flowing through, is used for part 7 in the middle of said is dispelled the heat, thus the not good problem of the radiator that solves middle part radiating efficiency.At this moment, when said first fan 4 and said second fan 5 are driven in when rotating simultaneously, they produced distinguished and admirable haply will be shown in arrow among Fig. 2 a side flow of past said radiator 3.The wind that this expression blows out from said first fan 4 must have the middle part 7 of some said radiators 3 of flowing through, is used for part 7 in the middle of said is dispelled the heat, thus the not good problem of the radiator that solves middle part radiating efficiency.
