Annular retaining walls are formed at peripheries of assembling holes, after the heat pipes are inserted into corresponding assembling holes, with a mode of stamping forming, one side of the annular retaining wall is provided with at least one bump or plane part to extrude heat pipes, so that the radiating fins can closely fixed on the heat pipes.

Description

A kind of integrated structure of radiating fin

Technical field

The utility model relates to a kind of integrated structure as radiating fin and heat pipe, refer to a kind of stamping forming mode of utilizing especially, moulding one salient point or planar portions on radiating fin are to be fixed on radiating fin the integrated structure on the heat pipe.

Background technology

The general heat abstractor of using heat pipe as heat radiation, use central processor (CPU) frequency among mainframe and personal computer more, and the heat rejection and removal of other process chip (as: drawing chip, display chip and north and south bridge chip or the like), when it uses, be after the heat absorption of heating end, to flash to gaseous state by the working fluid in the heat pipe, after condensation end carries out heat release and condense into liquid state, make working fluid be back to the heating end again, form a complete heat radiation circulation, reach the purpose of quick heat radiating.

See also Fig. 1, cutaway view when being combined in heat pipe for existing radiating fin, as shown in FIG., after earlier 10 groups of several heat pipes being located at a holder, the open end of its heat pipe 10 is to be parallel to each other, then, again with a plurality of radiating fins 20 in the storehouse mode, open end by a plurality of heat pipes 10 penetrates in regular turn, it utilizes radiating fin 20 formed a plurality of joining holes 201, for wearing of corresponding heat pipe 10, the periphery of its joining hole 201 also forms ring-type barricade 202, to make 20 of adjacent two radiating fins that fixing interval is arranged after establishing in group, when radiating fin 20 penetrated heat pipe 10, it was close or identical with heat pipe 10 calibers utilizing joining hole 201 circle footpaths, and the hardness of radiating fin 20 is greater than heat pipe 10 hardness, make that the ring-type barricade 202 of radiating fin 20 is able to packing on heat pipe 10 after the winding, and reach fixing purpose; But because radiating fin 20 windings are when heat pipe 10, its ring-type barricade 202 meetings and heat pipe 10 surperficial mutual friction mutually, cause the wearing and tearing of heat pipe 20, the caliber of heat pipe 10 is diminished gradually, and then cause between radiating fin 20 joining holes 201 and the heat pipe 10 crack to become big, therefore after winding, be easy to generate and rock, and reduce the contact area of heat pipe and radiating fin, and influence the radiating efficiency of heat abstractor integral body.

Because after existing radiating fin and the heat pipe winding, have in conjunction with unsteady shortcoming, the utility model the designer study intensively, and long-pending individual is engaged in the many years of experience of described item cause, designs a kind of brand-new radiating fin integrated structure eventually.

Summary of the invention

Main purpose of the present utility model is to provide a kind of auxiliary heat dissipation fin to be installed in integrated structure on the heat pipe, with the position of fixed radiator fin on heat pipe.

For reaching above-mentioned purpose, the integrated structure of radiating fin of the present utility model, be to be applied in a kind of heat abstractor that uses heat pipe as the conduction heat, its heat abstractor is by a holder, a plurality of heat pipes, and the plural pieces radiating fin is formed, at first be heat pipe to be organized earlier be located in the holder, so that the open end of heat pipe is parallel, be convenient to wear radiating fin, and utilization is at each joining hole periphery of radiating fin, all form a ring-type barricade, and when radiating fin is located in heat pipe, the joining hole of radiating fin is aimed at the open end of heat pipe, penetrate in regular turn again, by stamping forming mode, form at least one salient point or planar portions in ring-type barricade one side, and salient point or planar portions can so that radiating fin closely is fixed on the heat pipe, reach fixing effect by the outside inwardly extruding of ring-type barricade heat pipe.

Advantage of the present utility model is, it not only is difficult for getting loose and is easy to assembling, and after the ring-type barricade produces deformation, can increase the contact area of radiating fin and heat pipe, the radiating efficiency of heat abstractor is maintained or increases.
