Description

A kind of improved radiator buckle-type fin

Technical field

The utility model relates to a kind of improved radiator buckle-type fin, and it belongs to splice type finned radiator parts class.

Background technology

Radiator has a wide range of applications in numerous applications such as electronic applications, LED lighting fields, in radiator, finned radiator is important product type, wherein by monomer fin, mutually fasten the finned radiator forming, because the finned radiator cost that global formation is made is relatively lower, and in market, occupied important share.The radiator of prior art is that ZL200820146622.5 is disclosed with buckle-type fin, the disclosed buckle-type fin of ZL200820146622.5, comprise plate body, the first buckle and the second buckle, described the first buckle and the second buckle are positioned at the both sides of described plate body, and perpendicular to described plate body, be connected as one with described plate body simultaneously, on described the first buckle and the second buckle plate face perpendicular to plate body, offer inlay card through slot, nearly plate body one side of described inlay card through slot forms opening, simultaneously, described the first buckle and the second buckle extend the inlay card protuberance with inlay card through slot adaptation away from a side of plate body, under preferred version, on the side of described inlay card protuberance, be bent to form location chimb, like this, when the mutual inlay card of described buckle-type fin fastens, described inlay card protuberance is embedded in described inlay card through slot, under preferred version, the described location chimb being bent to form is fastened on the upper surface of described plate body through described inlay card through slot.The problem that this buckle-type fin of prior art exists is, in order to allow inlay card protuberance embed in described inlay card through slot, in particular for allowing location chimb through described inlay card through slot, out position could be realized when fastening assembling, at least to need to allow in the first buckling plate and the second buckling plate one form under external force deformation, due to the first buckle and the second buckle generally thinner, operating personnel are when operation, usually can excessively make the deformation of inlay card protuberance excessive owing to exerting oneself, and can not return to the state vertical with described plate body, the radiator that so final fastening splices, the first buckle and the second buckle fasten the plane injustice that rear its lateral surface of splicing forms, uneven reason is mainly described inlay card protuberance position projection, and in use, it is finally to fit with the heat radiation platen surface of heat source body that described the first buckle and the second buckle fasten the plane forming after splicing, the first buckle and the second buckle fasten the plane out-of-flatness forming after splicing, final radiating effect will directly be had influence on, obviously prior art has further improved necessity.

Summary of the invention

Order of the present utility model is to provide a kind of improved radiator buckle-type fin, the problem existing to solve prior art.

A kind of improved radiator buckle-type fin of the present utility model, comprise plate body, inlay card through slot, the relative both sides of described plate body are bent to form the first buckle and the second buckle, the outer side edges of described the first buckle and the second buckle connect respectively one with the inlay card protuberance of inlay card through slot adaptation, the outer side edges that it is characterized in that described the first buckle and the second buckle connects with described inlay card protuberance by a transition connection part bending inwards, within the outer side plane of the inlay card protuberance on described the first buckle and the second buckle is positioned at the parallel space that the inner side plane of described the first buckle and the second buckle limits, described inlay card through slot is formed on described plate body, described inlay card through slot is corresponding with the position of described inlay card protuberance.

As preferably, in the outer side edges of described the first buckle and the second buckle, be all formed with a notch, described in the transition connection part that bends inwards be connected on the base of described notch.

As preferably, on the limit, the left and right sides of described inlay card protuberance, be formed with respectively the tabs of downward bending, on described inlay card through slot, be formed with the line of rabbet joint that allows described tabs to pass, the distance that the outer side edges of the inner side edge of described tabs and described the first buckle and the second buckle is possessed is not less than the thickness of described plate body.

As preferably, outer side edges and the described plate body of described the first buckle and the second buckle have angle, and described angle is acute angle.

As further preferred, the outer side edges of described the first buckle and the second buckle extends outward a convergence protuberance, and the nearly plate body side of described the first buckle and the second buckle is formed with the draw-in groove with described convergence protuberance adaptation.

This improved radiator buckle-type fin of the present utility model, during use, adjacent two are inserted in the inlay card through slot on plate body and are formed and fasten by the inlay card protuberance on the first buckle and the second buckle, a complete radiator product of final formation, when fastening, the first buckle and the second buckle do not need to occur deformation and just can fasten such manner on the one hand, what is more important inlay card protuberance and inlay card through slot do not form impact to the outer side plane of described the first buckle and the second buckle, after fastening, the outer side plane of the first buckle and the second buckle will form a very smooth plane for this reason, the heat radiation platen surface laminating of this obvious smooth plane and heat source body will be very good, this is conducive to the effect of heat radiation, test shows, the radiator product that adopts this buckle-type fin splicing of the present utility model to assemble, in same specification situation, its radiating effect will have radiator product to promote 3% left and right compared with prior art, simultaneously, the manufacturability of prior art fastening assembling is also improved relatively, assembling speed will be faster than prior art.In addition, under preferred version, in the outer side edges of described the first buckle and the second buckle, be all formed with a notch, the described transition connection part bending inwards is connected on the base of described notch, can make like this transition point of attachment in described notch, thus make the first buckle and the second buckle outer side edges can with its before buckle-type fin fit tightly; On the limit, the left and right sides of described inlay card protuberance, be formed with respectively the tabs of downward bending, on described inlay card through slot, be formed with the line of rabbet joint that allows described tabs to pass, the distance that the outer side edges of the side of described tabs and described the first buckle and the second buckle is possessed is not less than the thickness of described plate body, inlay card protuberance can be tied described flanging through after the line of rabbet joint like this, thereby form permanently snap close, can prevent that like this fin snapping together is scattered in follow-up operation; On one position of the outer side edges of described the first buckle and the second buckle, extend outward a convergence protuberance, one side of described the first buckle and the nearly plate body of the second buckle is formed with the draw-in groove with described convergence protuberance adaptation, such structure can play guide function when fastening, simultaneously also many locator qualification positions structurally, are conducive to the lifting of structural stability; Outer side edges and the described plate body of described the first buckle and the second buckle have angle.After fastening like this, can form an annular radiator product, the radiator product of annular is very extensive in the application in the fields such as computer, LED light fixture.

In sum, obviously the purpose of this utility model is achieved.
