Description

Radiator

Technical field

The utility model relates to the radiator in a kind of mechanical engineering field cooling device, particularly relate to a kind of heat that is applied to distribute fast thermal source, can be as the purposes that cools, and make the circulation of air-flow more unobstructed, and can reach the radiator of promoting the cooling heat dissipation effect.

Background technology

When the work, this electronic building brick can generate heat as the electronic building bricks such as central processing unit of computer, and the electronic building brick temperature is too high to be influenced its task performance or burn in order to avoid, people usually can be on this electronic building brick one group of radiator of installing, use and wave the heat radiation energy fast.

Existing radiator of commonly seeing generally as shown in Figure 4, it mainly includes a fan 30 and a metal heat sink 40, this heat sink 40 is to extend the radiating fin 42 that is provided with plural number on base plate 41 up, make it have bigger cooling surface area, fan 30 is fixed on this heat sink 40, this radiator in use, be that base plate 41 with heat sink 40 supports and is affixed on the heating object, see through heat conduction to each radiating fin 42, produce air-flow by fan 30 energisings again and blow to heat sink 40, make the thermal transpiration of heat conduction to the heat sink 40, and then the heating object is produced the effect that cools.

Though only the existing radiator of aforementioned announcement can provide a kind of heat abstractor as the heat generating member cooling heat dissipation, yet the tube-axial fan of this radiator is to blow vertically downward from the top of heat sink, the swirling eddy that this fan is sent can vertically strike against and produce turbulent flow on the heat sink, make air-flow to circulate smoothly, and reduced the effect of air-flow cooling heat dissipation.

Problem at the radiator of aforementioned announcement, someone designs a kind of " radiator " structure that discloses as the 5327 No. four novel patent case of TaiWan, China patent announcement, if this radiator utilizes the heat sink pedestal to be volcano shape design, make on the pedestal bottom surface between between adjacent fin high in the middle of forming, the deep-slotted chip breaker that both sides are low, blow towards the below heat sink with tube-axial fan, the deep-slotted chip breaker that air-flow can be carried on the pedestal goes downstream, reduce the obstruction of air-flow, thereby improve the problem of the aforementioned existing radiator air turbulence of commonly using, increase the effect of air-flow cooling heat dissipation.

Though aforementioned existing radiator can utilize the deep-slotted chip breaker of bottom surface design between between adjacent fin on the heat sink, maybe can promote the effect of air-guiding, yet, the fan that this radiator uses is tube-axial fan, and be to utilize flabellum to rotate in the horizontal plane direction, in order to produce the swirling eddy that from top to bottom blows, and no matter the fin of the longitudinal extension on its heat sink is to arrange for radial or parallel shape, air-flow to rotation all can cause obstruction, so still have the problem of air turbulence, hinder the circulation of air-flow, effect improved still very limited to the cooling heat dissipation of thermal source.This shows that above-mentioned existing radiator still has many defectives, and demands urgently further being improved.
