Description
Technical field
The present invention relates to a kind of radiator, particularly a kind of phase-varying radiator that is used to electronic component to dispel the heat.
Background technology
Electronic component produces a large amount of heats usually in running, normally move for guaranteeing electronic component, and these caloric requirements are in time dispelled the heat away, installs a radiator on this electronic component usually additional and is its heat radiation.This radiator generally includes an absorber plate and is arranged at radiating fin on this absorber plate.This absorber plate is made by heat conductivity good metal materials such as copper, aluminium, but metallic plate is limited by the limited heat conductivity of material itself, if to the electronic component of golf calorific value, tangible thermal resistance can be produced and good heat radiating can't be reached, influence the operation stability of electronic component.
For promoting the efficient of radiator, industry also adopts at absorber plate one cavity is set, and encloses working fluids such as water, ethanol in this cavity, utilizes the phase change of working fluid to improve heat transfer rate.During work, working fluid is in the heat release zone of the heat absorption district of absorber plate endothermic gasification arrival absorber plate, cooling liquid then.For making workflow physical efficiency after the liquefaction be back to the heat absorption district of absorber plate sooner, this absorber plate is provided with a kind of capillary structure in the cavity periphery.Capillary structure generally is divided into three kinds of powder sintered capillary structures, netting twine capillary structure, groove capillary structure.Working fluid after the liquefaction is back to the hot zone and participates in the phase change circulation in capillary structure.Yet the back-flow velocity of hydraulic fluid and capacity of returns are subjected to the influence of factors such as capillary structure permeability, resistance, and its phase change in absorber plate circulates and has some setbacks, and the radiating effect of this radiator fails to produce a desired effect.For satisfying the radiating requirements of miniaturization day by day and high flux of heat electronic component, this radiator needs further to optimize.
Summary of the invention
In view of this, be necessary in fact to provide a kind of can with heat rapidly in time, the phase-varying radiator that passes effectively.
A kind of radiator, comprise an absorber and be located at radiator on this absorber, this absorber comprises an absorber plate and the cover plate that joins with this radiator, has a cavity between this absorber plate and the cover plate, be filled with working fluid in this cavity, this absorber plate is combined with first capillary structure layer, and this cover plate is combined with second capillary structure layer, and this second capillary structure layer is different from this first capillary structure layer.
Compared with prior art, above-mentioned radiator is provided with different capillary structure layer in diverse location, makes full use of the advantage of different capillary structure layer, make working fluid rapider, participate in phase change circulation fully and conduct heat.
Below with reference to accompanying drawing, in conjunction with the embodiments the present invention is further described.

Embodiment
As shown in Figure 1 to Figure 3, radiator of the present invention comprises an absorber 10 and is located at some radiating fins 30 on this absorber 10.Be provided with first capillary structure layer 116 and second capillary structure layer 156 in this absorber 10.
Above-mentioned absorber 10 comprises that a casing 110 and seal cover place the cover plate 150 on these casing 110 openings.Please consult Fig. 4 and Fig. 5 simultaneously, this casing 110 comprises that a rectangle tank 111 reaches from the outward extending flanging 112 of tank 111 4 upper peripheral edges.This tank 111 has rectangle heat absorption base plate 113 and reaches from four sidewalls 114 of this base plate 113 upwardly extending head and the tail connection of edge all around.The peripheral part sealing of above-mentioned cover plate 150 posts this flanging 112, thereby forms an airtight cavity 180 in absorber plate 10.Be filled with a certain amount of working fluid in this cavity 180.
Above-mentioned first capillary structure layer 116 covers the base plate 113 and four sidewalls 114 of above-mentioned tank 111.This first capillary structure layer 116 is formed by metal powder sintered.
Above-mentioned second capillary structure layer 156 covers 150 pairs of above-mentioned cover plates should the cavity part.This second capillary structure layer 156 is made by mesh wire, and it is close to the lower surface of this cover plate 150.This second capillary structure layer 156 is joined with above-mentioned first capillary structure layer 116, and the capillary structure of this two capillary structure layer is connected, and working fluid can enter first capillary structure layer 116 from second capillary structure layer 156.
The bottom of above-mentioned each fin 30 is formed with a flanging, and the flanging of some fins 30 forms the contact-making surface in conjunction with above-mentioned cover plate 150.
During use, the base plate 113 of above-mentioned casing 110 tanks 111 is close to the heat-generating electronic elements heat absorption, working fluid in the cavity 180 is that steam rises to cover plate 150 from these base plate 113 endothermic gasifications, working fluid is met at this cover plate 150 places and is coldly emitted heat and be cooled to liquid state, this heat and then be passed to fin 30 and distribute.Liquid working fluid infiltrates into second capillary structure layer 156 and flows to first capillary structure layer 116 along this second capillary structure layer 156, and then arrival base plate 113 carries out the phase change circulation.
Compared with prior art, above-mentioned radiator is provided with different capillary structure layer in cavity 180 peripheral diverse location places: heat absorption base plate 113 covers first capillary structure layer of being made by metal dust 116, because this first capillary structure layer 116 has good heat transfer, the heat that heat-generating electronic elements produces is passed to working fluid by it rapidly in time, post thread second capillary structure layer 156 of wire netting at cover plate 150 places away from heat absorption base plate 113, because this second capillary structure layer 156 has permeability and less flow resistance preferably, infiltrate through this second capillary structure layer 156 well in the condensed workflow physical efficiency of this place's heat release, and enter quickly in first capillary structure layer 116 and arrive heat absorption base plate 113 places and carry out the phase change circulation through this second capillary structure layer 156, the heat that heat-generating electronic elements is produced distributes quickly.
