Description

Radiating module

Technical field

The utility model relates to a kind of radiating module, belongs to electronic information technical field, belongs to thermal component in the electronic information technical field specifically, particularly the technical field of processor chips thermal component structure.

Background technology

Progress along with the electronic product production technology, the size of electronic building brick is done littler and littler, its arithmetic speed is but more and more faster, therefore the relative density in the electronic building brick unit volume improves, relative caloric value also increases, in stressing scientific and technological life-stylize, electronic product more and more is close in our daily life, requiring to carry light and computing fast under the situation, electronic product body external form is done littler and littler, but also have more function, make the density of electronic building brick that internal body contains increase, so electronic product design density change structurally is high, the caloric value of electronic product integral body also increases many relatively, if heat can't be effectively and is with fast from electronic building brick, increase the probability of electronic product hot stall easily, so the heat dissipation design of electronic building brick when running is also increasingly important.

An electronic system is under operating state, main heating source is each processor chips, these chips cause the phenomenon of whole system temperature distributing disproportionation easily, if the system radiating design is bad, easily produce the too high phenomenon of single point temperature, focus (Hotspot) can make chip that the hot probability of working as takes place and uprise, the possibility of product bug also increases relatively, in order to solve the heat dissipation problem of electronic building brick, generally all be that conventional axial-flow fan (Axial flow fan) installs radiating fin (Heat sink) additional, owing to the progress of mobile computer, heat pipe (Heat pipe) is general day by day with the application of centrifugal fan (Centrifugal fan) in recent years; But because economic consideration, still conventional fan cooperates radiating fin at present, so very important angle is just being played the part of in the design of fin.

Get out a plurality of honeycomb openings so just there is the dealer to utilize on a monoblock aluminium block or the copper billet with bore mode, forming cellular fin is fixed on the pedestal and uses, though the cellular fin of this kind can effectively be arranged source of heat release by plural honeycomb opening, but on processing and fabricating, then comparatively do not meet economic benefit, get out one by one honeycomb mouth for must be on aluminium block or copper billet seeing through bore mode, the problem that it is derived, as: processing difficulties, time and effort consuming, cost improve, and the disappearance that can't effectively grasp on the product quality.

So, how to solve above-mentioned problem of commonly using and disappearance, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention
