Abstract
The utility model discloses a buckling structure of radiating fins used for a portable computer, which comprises a radiating component formed by a plurality of pieces of flaky radiating fins in a stacked way, each radiating fin is provided with an upper bending part and a lower bending part with same direction, at least one buckling structure is arranged on the radiating fin body, and the main body of a rear radiating fin is right buckled on the main body of a former radiating fin. Since at least one buckling structure is arranged on the radiating fin body, the main body of the rear radiating fin can be rightly buckled on the main body of the former radiating fin, the connecting point between the upper bending part and the lower bending part of the radiating fin is ensured smooth, the buckling area is in sufficient contact with the thermal pipe, no blow hole exists at the juncture of the buckling points, and both the contact area and the welding effect with the radiating fins are good. In short, the utility model has the advantages of simple structure, low cost and better radiating effect.
Description
Technical field
The utility model relates to a kind of radiating fin, especially a kind of buckling structure of radiating fin for portable computer.
Background technology
The radiating fin that present laptop computer is used has a variety of structures, the tie point of each heat radiator is located at kink and once between the kink more, promptly by on the adjacent heat radiator, following kink is corresponding to link to each other, fastening point like this is in, the surface of following kink, make the fastening zone be difficult to reach and fully contact (it is smooth to be difficult to welding) with heat pipe, and there be the contact area and the welding effect that can influence heat pipe and heat radiator in the holes of button point junction, so the heat from the heat pipe to the heat radiator passes effect and will be affected, increased the thermal resistance from the heat pipe to the heat radiator, thermal diffusivity is not good.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of buckling structure of radiating fin for portable computer, and this buckling structure radiating effect is better.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of buckling structure of radiating fin for portable computer, comprise the radiating subassembly of forming by the piece-shape type radiating fin institute storehouse of most sheets, radiating fin has in the same way a last kink and a kink once, between described upward kink and the following kink is the body of radiating fin, the body of radiating fin is provided with at least one fastening structure, and the body of back a slice radiating fin just can be fastened on the body of preceding a slice radiating fin.
One of fastening structure is: goes out a connecting hole on the body at least, goes out the part pull-up and form hook, and when each radiating fin links to each other, the connecting hole of a slice radiating fin before the hook of back a slice radiating fin just can place.
Two of fastening structure is: go out a connecting hole on the body at least, go out and be provided with the dual-side that symmetrical pull-up forms in the part, the dual-side end forms T type hook, T type hook forms protuberance in the middle of the end, when each radiating fin links to each other, the connecting hole of a slice radiating fin before the dual-side end of back a slice radiating fin hook just can place.
Also can go out two connecting holes on the body, two connecting holes are spaced apart on the diagonal line of body.
The beneficial effects of the utility model are: because the body of radiating fin is provided with at least one fastening structure, the body of back a slice radiating fin just can be fastened on the body of preceding a slice radiating fin.Can guarantee the smooth of the last kink of heat radiator and following kink junction like this, fasten the zone and can fully contact, and a button point junction do not have the holes existence with heat pipe, thus all fine with the contact area and the welding effect of heat radiator.Generally speaking, the utility model is simple in structure, cost is low and radiating effect is better.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a heat radiation fin structure synoptic diagram described in the utility model;
Fig. 2 is the another kind of structural representation of radiating fin described in the utility model.
Embodiment
Embodiment: a kind of buckling structure of radiating fin for portable computer, comprise the radiating subassembly of forming by the piece-shape type radiating fin institute storehouse of most sheets, radiating fin has in the same way a last kink 1 and a kink 2 once, between described upward kink and the following kink is the body of radiating fin, the body of radiating fin is provided with at least one fastening structure 3, and the body of back a slice radiating fin just can be fastened on the body of preceding a slice radiating fin.
One of fastening structure is: goes out a connecting hole on the body at least, goes out the part pull-up and form hook, and when each radiating fin links to each other, the connecting hole of a slice radiating fin before the hook of back a slice radiating fin just can place.
Two of fastening structure is: go out a connecting hole on the body at least, go out and be provided with the dual-side 51 that symmetrical pull-up forms in the part, the dual-side end forms T type hook 52, T type hook forms protuberance in the middle of the end, when each radiating fin links to each other, the connecting hole of a slice radiating fin before the dual-side end of back a slice radiating fin hook just can place.
Go out two connecting holes on the body, two connecting holes are spaced apart on the diagonal line of body.
Certainly also having other various fastening structure modes, all is this routine claimed scope.
