Description

Heat abstractor

[technical field]

The present invention relates to a kind of heat abstractor, be meant a kind of heat abstractor that is used for electronic component especially.

[background technology]

As everyone knows, electronic component such as central processing unit produces a large amount of heat in running.For preventing that thereby this heat-generating electronic elements from causing its temperature rising to cause its fluctuation of service, this electronic component need install a heat abstractor usually additional with auxiliary its heat radiation because of the accumulation of heat.

Usually, a heat abstractor comprises a conductive sole plate and is located at some radiating fins on this base plate.During use, a bottom surface of this base plate is close to heat-generating electronic elements and is absorbed heat, thereby and this heat transferred to fin is distributed to surrounding space.

But along with the development of computer industry, the function of electronic component is become stronger day by day, thereby produces increasing heat.Above-mentioned simple heat abstractor by heat conducting and radiating can not distribute the heat that electronic component produces timely, thereby increasing heat accumulation influences the runnability of electronic component on electronic component.For improving the heat dispersion of this heat abstractor, usually a fan is installed on this fin, thereby the strong convection air is provided and quickens heat radiation to this fin.Yet, the development of computer industry, the integrated level and the function of electronic component constantly promote, cause more heat to produce, and more and more electronic component need heat radiation, in addition, the miniaturization of computer volume trend all needs this heat abstractor further to optimize, to satisfy radiating requirements.

[summary of the invention]

In view of this, be necessary to provide a kind of heat dispersion good and be the heat abstractor of a plurality of electronic element radiatings.

A kind of heat abstractor, be used for the auxiliary electron element radiating, it comprises a radiator, is located at the fan of this radiator one side and the fan fixer between this radiator and fan, this fan fixer comprises the panel of fixing this fan and the cover body of this radiator one end of shade, the part of this fan stretches out this cover body and radiator, thereby the part air communication of this fan is crossed this radiator, and the part air communication is crossed the space beyond the radiator.

Compared with prior art, the part of fan stretches out cover body and radiator in the heat abstractor, thereby the part air communication that this fan produces is crossed this radiator, cools off this electronic component, and the part air communication is crossed the space beyond the radiator, the cooling other electron component.

With reference to the accompanying drawings, the invention will be further described in conjunction with the embodiments.
