Description
Technical field
The utility model relates to a kind of structure of heat abstractor, especially relates to a kind of being applied in the electronic installation, simultaneously the structure of the heat abstractor that a plurality of heating electronic chips are dispelled the heat.
Background technology
Development along with electronics technology, the integrated level of electronic chip (as the central processing unit of computer) strengthens, operating rate also constantly increases, and therefore heat abstractor must be set to reduce the surface temperature of electronic chip on the surface of electronic chip, keeps its normal work.But we still will consider several factors when solving its heat dissipation problem, and the central processing unit with computer is that example illustrates below.
The fast development of the arithmetic speed of the central processing unit of computer, the solution of the heat dissipation problem of central processing unit just becomes the problem that the emphasis consideration is wanted the time in the main frame design, especially more is rich in challenge for the little computer of volume such as the design of notebook computer.Notebook computer is compact, and is therefore very high to the requirement of the heat abstractor in the notebook host.
The heat abstractor of the central processing unit of present most of notebook computers is to connect a radiator by heat-radiating substrate, radiator comprises a radiator fan and the radiator fan air outlet radiating fin that be provided with of configuration on it, and what have also is provided with heat pipe on heat-radiating substrate.Heat conducts to radiator through heat pipe, in the heat conductive process, heat pipe and spreader surface can be to external radiation part heats, and still most of heat all is to pass through the radiating fin of radiator to external radiation, and radiator fan has increased air flows and quickened dispersing of heat.But this kind heat abstractor is because area of dissipation is certain, and the radiating effect of the single fan of employing is limited, so the heat radiation power of this device has certain limit.
