Description
Technical field
The utility model relates to a kind of guiding device, more specifically, relates to a kind of guiding device that is applied to heat abstractor.
Background technology
Along with the development of electronics technology technology, computing machine trends towards allowing central processing unit operate with high clock pulse in order to reach the demand of high execution speed now.Or even by overclocking (over clocking), make the central processing unit can be with the velocity process data of the limit.Therefore, the more electric power of computing machine consumption now also make central processing unit produce more thermal energy, and must be in the face of serious overheated problem.
Generally speaking, though central processing unit is little, the heat energy that ejects is many.To so many heat energy be gone from the place that central processing unit is transferred to other, just need effective heat abstractor.In case, there is not excellent heat abstractor that heat energy is dissipated from central processing unit immediately, then central processing unit at once will be overheated, and can't operate, even cause taking place when the machine situation.
Therefore, how designing effective heat abstractor is maximum at present problem.And present heat abstractor is nothing more than comprising heat radiator (heat sink) and fan (fan).The benefit of these two kinds of heat abstractor maximums is that cost is low, is therefore accepted by most manufacturer.
This heat abstractor is to utilize convection current and these two mode heats of conduction to distribute.Briefly, conduction is meant the direct contact that sees through physics mode.Just make heat radiator directly be linked to central processing unit, and the former can obtain the latter's heat energy by conduction pattern.As for convection current, utilize fan to make cross-ventilation exactly, so that most of heat energy convection current that heat radiator was obtained is spread out of.Therefore, if fan can effectively spread out of heat energy, then this heat abstractor can prevent that just the situation of computer overheating from taking place.
And the usefulness quality of fan mainly depends at rotating speed and flabellum itself.Generally speaking, a good fan must have big flow.And under same rotating speed, the flow of large-sized fan is greater than undersized fan, and the noise that the former produced is also less.What therefore, the fan of the heat dissipation reduced size of large-sized fan came is good.
But because the relation of computer specifications standard, the size of present heat abstractor has certain restriction, can't amplify arbitrarily.And the also restriction thereupon of the size of fan makes heat dissipation to improve by the mode of selecting the large scale fan.And in order to satisfy radiating requirements, the deviser just improves the rotating speed of undersized fan as far as possible, to reach the flow the same with large-sized fan, therefore causes more serious high noisy puzzlement also.
For solving the above problems, have the design in some computing machines that are installed in small size for large-sized fan at present.
As shown in Figure 1, this existing heat abstractor 1 comprises a conduit 11, a fan 13 and a heat radiator 15.
At this, heat radiator 15 is connected in a central processing unit (not shown), in order to absorb the heat energy that central processing unit produced.And conduit 11 has a upper shed 111 and a under shed 113.This conduit 11 utilize two baffle plates 115 in addition reinforcement fix, and utilize several screw (not shown) to be linked to fan 13 and heat radiator 15 respectively.And rotate by fan 13, make air enter conduit 11 by upper shed 111, send by after-opening 113 again, heat radiator 15 is dispelled the heat.Therefore, can reach the effect of the heat energy that reduces central processing unit.
Above-mentioned mode is to add conduit 11 between fan 13 and heat radiator 15, is installed in the small size for large-sized fan 13.Yet, as shown in Figure 2,, this conduit 11 all can block the direction of air flow because being the screw fixed position 117 of square and baffle plate 115 and upper and lower opening 111,113, and the resistance when producing air flow causes air flow quite to have some setbacks on the contrary.Therefore, the heat dissipation of this heat abstractor 1 is not good.
Therefore, need a kind of function that can provide large-sized fan to be installed in small size, and take into account the heat abstractor of high heat dissipation efficiency and low noise properties.
