Background technology
All be provided with different electronic building bricks on the circuit board of electronic equipment, the electronic building brick of CPU etc. for example, but along with developing rapidly of electronic correlation industry, make CPU arithmetic speed efficient promote apace, but make its caloric value also relatively more and more high, even, make that also heat promotes more because of the confining factor of casing etc.Therefore, in order to keep the stability of electronic equipment in running, the heat sinking function of electronic building brick just belongs to a considerable ring.
The heat abstractor that is used in various electronic building bricks at present has many patterns, announce on March 1st, 2006 with TaiWan, China, the heat abstractor of certificate number number: M288399 is an example, and its announcement has a radiating module, a plurality of heat pipe, a heat-absorbing model, anchor clamps and a stuck-module.Wherein, radiating module is made up of a plurality of radiating fins that are arranged side by side, each heat pipe one end is to assemble with radiating module, and the heat pipe other end is configured in the heat-absorbing model, anchor clamps are withheld in a heat generating components (electronic building brick) and the heat-absorbing model outside, stuck-module is installed between heat generating components and the heat-absorbing model, in order to heat generating components is fixing with heat-absorbing model.In addition, the compound mode of aforesaid heat-absorbing model and heat pipe is welding.
But, above-mentioned heat abstractor, though the effect that provides electronic building brick to disperse heat can be provided, heat-absorbing model is reciprocally to weld with heat pipe, when causing described heat abstractor actual assembled in electronic equipment, it is earlier after welding with heat pipe with heat-absorbing model that the assembler certainly will want, just can assemble other described member in electronic equipment, therefore, for the assembler, described heat abstractor needs mode and the steps of understanding these welding more, still has in the unavoidable combination not have the locating of convenience.
In addition, what is particularly worth mentioning is that, because of welding is the mode that adopts soldering mostly, but is mixed with plumbous metal ingredient in the tin cream of its use (bar), in recent years as all not having leaded scolding tin in the bright taboo electronic equipment of country of European Union etc., the product, therefore, contain the trend that plumbous soldering processing procedure can't meet various countries institute plaintext standard, for the researcher, the product that it is developed, the trend that can meet Wuxi (lead) processing procedure promptly is an important problem.
So improving of the above-mentioned disappearance of the utility model designer thoughts is that the spy concentrates on studies and cooperates the utilization of scientific principle, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned disappearance finally.
