More summary of the invention and effect thereof, by exposure in explanation subsequently.
Accompanying drawing explanation
Fig. 1,2 is display preferred embodiments of the present invention.
Fig. 3 is the radiator in the described preferred embodiment of display.
Fig. 4 is the basic framework that display known technology has the heat abstractor of bottom blowing type double fan.
Embodiment
The preferred example of Fig. 1, a 2 display heat abstractor 1 of the present invention.As shown in Figure 1, described heat abstractor 1 is mounted on a circuit board 6, and comprise fan housing 2, radiator 3,1 first fan 4 and one second fan 5, wherein:
Described fan housing 2 includes one first through hole 222 and one second through hole 224 of longitudinal separation arrangement.
Described radiator 3 is located in described fan housing 2, and comprise multi-disc lateral separation fin 30 side by side.
Described first fan 4 be located on described fan housing 2 and position in the first through hole 222 of described fan housing 2, described second fan 5 be located on described fan housing 2 and position in the second through hole 224 of described fan housing 2.The wind that described first fan 4 and described second fan 5 produce is all blow to described radiator 3.
Wherein, described fan housing 2 is mainly used for fixing first, second fan 4,5 described, in actual applications, also can adopt the mode that support is hung, is fixed on described radiator 3 by first, second fan 4,5.
As shown in Figure 2, one heat source-contacting surface 31 is arranged at the bottom of described radiator 3, described heat source-contacting surface 31 is used to abut on a heat-conducting plate 60 (such as copper soleplate), described heat-conducting plate 60 abuts in the thermal source 61 on described circuit board 6, and the heat energy of described thermal source 61 is promptly led on described radiator 3.In this example, described circuit board 6 is computer display cards, and described thermal source 61 refers to the GPU of position on described computer display card.In addition, the heat source-contacting surface 31 of described radiator 3 also can directly abut on described thermal source 61.
Specifically, obviously can see that described first fan 4 is all arranged to be obliquely installed with described second fan 5 in fig. 2, they are all obliquely installed for the heat source-contacting surface 31 of described radiator 3, and their incline direction also be identical.So, the wind-force that described first fan 4 blows to mid portion 7 is greater than the wind-force that described second fan 5 blows to mid portion 7, eliminates the Zhi Feng district that known technology has.This represents that the wind blown out from described first fan 4 must have the middle part 7 that some flow through described radiator 3, is used for dispelling the heat to described middle part 7, thus the problem that the radiator solved middle part radiating efficiency is not good.Now, when described first fan 4 is driven in rotation with described second fan 5 simultaneously, they produce distinguished and admirable haply will as shown in arrow in Fig. 2 toward as described in the side flowing of radiator 3.This represents that the wind blown out from described first fan 4 must have the middle part 7 that some flow through described radiator 3, is used for dispelling the heat to described middle part 7, thus the problem that the radiator solved middle part radiating efficiency is not good.
In this example, described first fan 4 is identical with angle of inclination R1, R2 of described second fan 5, but, also can select to make them have different angles of inclination, but still identical incline direction will be kept.Wherein, the angle of inclination of described first fan 4 is larger, represents its wind blowing part 7 in the middle of described radiator 3 just the more.Usually, the angle of inclination selecting 5 ~ 45 degree is preferably.
In addition, the bottom of described radiator 3, except described heat source-contacting surface 31, also has a wind-guiding inclined plane 32.Described wind-guiding inclined plane 32 is towards described first fan 4, and its incline direction is in contrast to described first fan 4.As can be seen from Figure 2, described wind-guiding inclined plane 32 is longer, and/or angle of inclination S larger (maximum can not more than 90 degree), it is the more blow part 7 in the middle of described radiator 3 that the wind that described first fan 4 will be made to produce has, thus promotes the radiating efficiency of described radiator 3 further.Usually, the angle of inclination selecting 5 ~ 45 degree is preferably.
Refer to Fig. 3, it mainly shows the bottom of described radiator 3, use and point out that described radiator 3 is by more described fin 30 laterally and connect and form, each fin 30 comprise a substrate 301 and respectively from described substrate 301 extend out always to sheet 302 and one oblique 303.Wherein, the straight of multiple fin 30 forms above-mentioned heat source-contacting surface 31 jointly to sheet 302, the oblique 303 wind-guiding inclined plane 32 that composition is above-mentioned jointly of multiple fin 30.In any case this is one of better embodiment of described radiator 3, in fact also can select to manufacture described radiator 3 by aluminium extruded type mode.
Referring again to Fig. 2,3, each fin 30 in the middle of this example also has one first inclined side 304 and one second inclined side 305.Described first hypotenuse 304 is next-door neighbour and faces described first fan 4, and its inclination trend is same as described first fan 4.Described second hypotenuse 305 is next-door neighbour and faces described second fan 5, and its inclination trend is same as described second fan 5.So, the width that described first fan 4 just can be consistent with the gap between described radiator 3, and the width that described second fan 5 also can be consistent with the gap between described radiator 3.This has the impact in front to the integral heat sink efficiency of heat abstractor of the present invention.
