Further, said base plate comprises one first groove structure.
Further, said fin comprises one second groove structure.
Further, said front end housing also has a laser transmission hole.
Further, said front end housing comprises one second comb-type structure.
Further, said shell body comprises one first comb-type structure.
Further, the protruding beam of said first groove structure is corresponding each other with the broach of said second comb-type structure.
Further, the protruding beam of said second groove structure is corresponding each other with the broach of said first comb-type structure.
Further; First installing hole that has on the said front end housing with said shell body on the 7th screwed hole that has corresponding; First screwed hole that has on second installing hole that has on the said front end housing and the said base plate is corresponding; Second screwed hole that has on the 3rd installing hole that has on the said front end housing and the said base plate is corresponding, and the 6th screwed hole that has on the 4th installing hole that has on the said front end housing and the said shell body is corresponding; Said base plate and said shell body pass through screw; The installing hole of said fan respectively with said shell body on first screwed hole, second screwed hole that have on the 5th screwed hole, the 8th screwed hole and the said base plate that have corresponding, through screw said fan is installed on said base plate and the said shell body.
The heat abstractor that is used for laser of the present invention in the course of the work; It is inner that said laser is installed in said shell body; Said fan is installed in said heat abstractor afterbody, and the air-flow part of said fan output is directly blown on said fin, scatters to both sides along its second groove structure; Another part air communication excessively directly blows to said base plate; Come out from the heat abstractor front end along said first groove structure from the heat abstractor afterbody, fully increased area of dissipation, and improved convection effects.
Compared with prior art, the present invention has the following advantages:
1, big to flow area, speed is fast, and convection effects is good.Because directly through fin and base plate radiator structure, therefore, convection velocity is fast for the air-flow of fan, area is big, and convection effects is obvious.
2, heat-conducting area is big, and heat radiation obviously.Because said structure has not only utilized base plate as main heat-transfer device, has also adopted special heat-transfer device, heat-conducting effect is obvious.
3, simple and compact for structure, cost is low.Compare with existing common laser, said structure is compact more, and heat-conducting effect is better, in field of lasers, means that littler structure can make more high-power laser.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
