Abstract
The heat sink is in use for carrying out thermolysis for at least a radiant electronic element (REE). The heat sink includes a fin set and a centrifugal fan. Being hot connected to REE, the fin set is in use for absorbing quantity of heat generated by REE. The fin set is setup at uptake of the centrifugal fan. Airflow generated by the centrifugal fan blows the fin set to carry away quantity of heat absorbed by the fin set. Fins in the fin set are superposed and arranged at the uptake. Fins are arranged along direction nearly parallel to rotor shaft of the centrifugal fan so as to form fin set.
Description
Technical field
The invention relates to a kind of heat abstractor, particularly about a kind of heat abstractor that is used for electronic element radiating.
Background technology
Along with improving constantly of central processing unit electronic component power such as (CPU), heat dissipation problem more and more is subject to people's attention, and is all the more so in notebook computer.In order to take away the heat that system produces efficiently in limited space, industry mainly adopts by the mode of fin, heat pipe and radiator fan combination and dispels the heat at present.The heat conduction path of this mode is: the heat that CPU produces passes to fin through heat pipe, and the air-flow that is produced by the radiator fan heat that will reach fin is taken away again.So radiator fan plays the heat that system is produced and passes to important function outside the system in the heat radiation module, so the collocation of radiator fan and fin has very large influence to the performance of system.
Be illustrated in figure 1 as a traditional heat abstractor 20, this heat abstractor 20 comprises a fins group 24 and a centrifugal fan 22.This fins group 24 comprises some fins 242, this fins group 24 be arranged at centrifugal fan 22 air outlet 211 places and with heat-generating electronic elements (figure do not show) hot link to absorb the heat that this heat-generating electronic elements produces.This centrifugal fan 22 comprises a shell block 222, a stator (figure does not show) and can be around the rotor 223 of this stator rotation, and this rotor 223 is arranged in this shell block 222.When centrifugal fan 22 operation, thereby this rotor 223 rotates counterclockwise around stator and produces air-flow and blow to fins group 24, takes away with the heat that fins group 24 is absorbed, thereby reaches the purpose of heat radiation.
This heat abstractor 20 is in when work, and this shell block 222 is guided air-flow the air outlet 211 of centrifugal fan 22 into, and air-flow is left centrifugal fan 22 and blowed to fins group 24 by these air outlet 211 places.Upside 246 in fins group 24, fin 242 almost parallels at airflow direction and this place, and at the downside 244 of fins group 24, airflow direction but forms an angle with the fin 242 at this place, and therefore, the air-flow that flows to the downside 244 of fins group 24 can bump with downside fin 242, make air-flow that certain kinetic energy rejection be arranged, the speed of air-flow will significantly reduce, and can reduce the heat exchanger effectiveness of fins group 24 and air-flow like this, causes the radiating efficiency of heat abstractor 20 effectively to be promoted.
Summary of the invention
In view of this, be necessary to provide a kind of heat abstractor that promotes heat dispersion that has.
A kind of heat abstractor, be used for heat-generating electronic elements is dispelled the heat, this heat abstractor comprises a fins group and a centrifugal fan, this fins group and heat-generating electronic elements hot link are to absorb the heat that heat-generating electronic elements produces, this fins group is arranged at the air outlet place of centrifugal fan, and the air-flow that this centrifugal fan produces blows to this fins group so that the heat of its absorption is taken away.The fin stacked arrangement of this fins group is in this air outlet place.
Because the fin of this fins group is the air outlet place of stacked arrangement in centrifugal fan, the direction that this fins group and the compound mode of centrifugal fan can make air-flow is parallel as far as possible with the gas channel between the fin of fins group, air-flow can flow through gas channel reposefully like this, reduce the loss of air-flow kinetic energy when flowing through fins group, thereby improve the heat exchanger effectiveness of fins group and air-flow, so the heat dispersion of heat abstractor is promoted effectively.
