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 on the electronic component especially.

Background technology

Along with developing rapidly of electronic industry, increase substantially as the arithmetic speed of electronic component in the computer, the heat of its generation also increases severely thereupon, and how the heat with electronic component distributes, and to guarantee its normal operation, is the essential problem that solves of dealer always.As everyone knows, the central processing unit that is installed on the motherboard is the core of computer system, and when computer moved, central processing unit produced heat.Too much heat can cause central processing unit normally to move.For effectively distributing the heat that central processing unit produces in running, on circuit board, install a heat abstractor that contacts with central processing unit additional usually so that the heat of its generation is distributed.

Be provided with devices such as some transistors, electric capacity around the central processing unit on the computer motherboard.When computer moved, these devices also can produce a large amount of heats, and these heat transferred can cause motherboard to heat up, and then influence systematic function to motherboard.

One fan is installed on heat abstractor in the prior art usually, the airflow passes radiator that fan produces, thus improve radiating efficiency.For example U.S. Patent application the 6th, disclosed a kind of heat abstractor 304,445 B1 numbers, comprised that a radiator, is installed on the radiator fan and a cover body of radiator one side, this radiator is made up of some radiating fins, forms some air ducts towards fan between the described radiating fin.The forced draft that fan provides is blown over described air duct, and radiator is taken away from the heat that central processing unit absorbs, and reaches the effect of cooling central processing unit.

Because cover body encloses radiator in it, the air-flow that fan produces be subjected to the gathering of cover body and take into account less than around the heat radiation of electronic component.If cover body is removed the air-flow of fan generation is blowed everywhere, then can reduce the heat dispersion of radiator, also can disperse owing to air-flow certainly, the radiating effect of electronic device is all not good around the central processing unit.

Therefore, need a kind of new heat abstractor of design, the heat that this heat abstractor not only can produce central processing unit well distributes, and also can dispel the heat to the electronic component around it targetedly.

Summary of the invention

The present invention aims to provide a kind of heat abstractor that can dispel the heat to a plurality of heat-generating electronic elements simultaneously.

A kind of heat abstractor, comprise a radiator and a cover body, this cover body encloses this radiator in it and forms passage by radiator, this passage comprises an air inlet and air outlet, one fan is installed on the air inlet place of cover body, and forms of linking up above-mentioned passage and cover body outside are installed on cover body in addition.

Compared with prior art, this heat abstractor can be taken into account the radiating requirements of electronic device around central processing unit and the central processing unit pointedly, and obtains preferable radiating effect simultaneously.

In addition, this heat abstractor is installed an active window body, and window structure can be selected the different selection scheme of opening or closing according to different demands.

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