Abstract

The utility model discloses a clamping-type radiating fin comprising a radiating fin board body and a clamping strip. The radiating fin board body is molded with clamping grooves. The middle part of the clamping strip is a clamping rod. The two ends of the clamping rod are molded with elastic clamping hooks respectively. The clamping rod on the clamping strip is arranged in the clamping grooves. When the clamping-type radiating fin is being assembled and after the radiating fin is arranged on the surface of an integrated circuit, elastic connecting rods at the two ends of the clamping strip are directly pressed down and thus the clamping hooks are allowed to be clamped in the corresponding clamping grooves or clamping pieces; and for the same reason, during disassembling, the clamping hooks are allowed to separate from the corresponding clamping grooves or the clamping pieces through just pressing down the elastic connecting rods and utilizing elasticity of the elastic connecting rods themselves, so that the radiating fin is assembled and disassembled much conveniently.

Description

A kind of plug-in fin

Technical field:

The utility model relates to a kind of fin, is specifically related to a kind of plug-in fin.

Background technology:

At electronic technology field, along with integrated circuit develops to high-density integrated, the heat of its generation is also more and more, corresponding its temperature is also more and more higher, and the stability of excess Temperature when integrated circuit is moved is totally unfavorable, and for this reason, industry is installed a fin usually on integrated circuit, and make integrated circuit surface and fin close contact by supplementary meanss such as screw, double-screw bolts, be beneficial to heat is discharged.But by auxiliary installation methods such as screw, double-screw bolts, its assembly and disassembly are all extremely inconvenient.

The utility model content:

The purpose of this utility model is a kind of plug-in fin that provides with regard to being the weak point that exists for prior art, and it has the characteristics of assembling, convenient disassembly and good heat dissipation effect.

For achieving the above object, a kind of plug-in fin of the present utility model, comprise fin plate body, card article, and heat sink plate is body formed draw-in groove; The mid portion of card article is kelly, and the two ends of described kelly form respectively elastic fastening hook; Kelly on card article is placed in described draw-in groove, and card article well is pressed on fin, guarantees to can be good at contact when fin is installed on integrated circuit surface.

During the utility model assembling, after fin is installed on integrated circuit surface, the flexible connecting rod at card article two ends is directly pressed down, snap fit is stuck on corresponding draw-in groove or shackle member; As a same reason, during dismounting,, as long as press flexible connecting rod, utilize the elasticity of flexible connecting rod self, the snap fit corresponding draw-in groove of disengaging or shackle member are got final product, greatly facilitate dismounting and the assembling of fin.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is the utility model fin and card article assembling schematic diagram;

Fig. 2 is the structural representation of the utility model fin;

Fig. 3 is the structural representation of the utility model snap fit;

The main element symbol description

1---fin plate body 11---draw-in groove 10---radiating wing

2---card article 20---kelly 21---elastic fastening hook

Embodiment:

See that Fig. 1 is to shown in Figure 3: a kind of plug-in fin of the present utility model, comprise fin plate body 1, card article 2, fin plate body 1 forms draw-in groove 11; Card article 2 by kelly 20 and kelly 20 two ends respectively the elastic fastening hook 21 of moulding form, elastic fastening hook 21 is the rightabout design; Kelly 20 on card article 2 is placed in described draw-in groove 11.

In the present embodiment, the centre position of described fin plate body 1 also is provided with the radiating wing 10 that is "T"-shaped shape, the heat of fin concentrates on middle part usually, radiating wing 10 designs by "T"-shaped shape, can increase the area of dissipation of fin middle part, to reach better radiating effect.

The foregoing is only the preferred embodiment that embodies the utility model principle, therefore do not limit protection range of the present utility model, every equalization of doing according to the utility model change with modify and all belong to the scope of the claims that the utility model contains within.
