Abstract

The utility model relates to a fin solves and improves the performance problem. The high-density fin type radiating fin is composed of a base part and a plurality of fins, and is characterized in that a plurality of caulking grooves are formed on the base part, each caulking groove is at least provided with a protruding barb, concave-convex lines are arranged on two surfaces of each fin to form a concave-convex surface and a plurality of grooves which are arranged at equal intervals, and the lower ends of the fins can be embedded into the grooves of the base part from the side surface of the base part, so that the fins are vertically arranged on the base part. For heat dissipation.

Description

High density fin type fin

The utility model relates to fin, refers in particular to a kind of fin type fin.

General radiator is under forced convection and confined space condition restriction, desire is brought into play maximum heat-sinking capability, wherein a kind of design is exactly the area that increases radiator, widely used is exactly fin type, as shown in Figure 1, fin adopts the type of squeezing design, but owing to produce the restriction of condition of molding, spacing P, thickness T and the height H etc. of the fin 11 of fin 1, all proportional restriction, H=10T, H=6P, it is long-pending therefore can't to reach the high density multiaspect, on reality is used, obviously produce inconvenience and shortcoming, can not satisfy instructions for use.

The purpose of this utility model just provides a kind of heat sinking function high density fin type fin preferably.

The purpose of this utility model is achieved in that high density fin type fin, it is made up of a base portion and a plurality of fin, it is characterized in that: base portion is provided with the multiple tracks caulking groove, each caulking groove is provided with one at least and protrudes barb, fin two faces are provided with concave convex texture to form the groove that male and fomale(M﹠F) and multiple tracks equi-spaced apart are provided with, the fin lower end can be embedded the groove of base portion by the base portion side, each fin is erect be arranged on the base portion.

Above-mentioned design, but the cooperating of mat barb and groove prevent that fin from deviating from from caulking groove, and, wherein, the scarf of base portion and fin can on adhesive glue is arranged.Obviously, this design not only has reliability preferably, and has better radiating effect again.

Below by drawings and Examples the utility model is described further again:

Fig. 1 is the schematic diagram of existing fin type fin;

Fig. 2 is the three-dimensional combination of a utility model schematic diagram;

Fig. 3 is the utility model plane combination schematic diagram;

Fig. 4 is the utility model plane decomposing schematic representation.

As Fig. 2,3,4, this fin 1 is by the good material of thermal conductivity such as aluminium, comprises that a base portion 10 and a plurality of fin 11 form, and equidistantly is interval with multiple tracks caulking groove 12 on base portion 10 end faces, is provided with a barb 13 that protrudes in each caulking groove 12 at least.Fin 11 is one to have the lamellar body of suitable thickness, its lower end just can embed the caulking groove 12 of

base portion

10,11 2 of fins also are provided with concave convex texture 14, to form male and fomale(M﹠F), in order to increase area of dissipation, and this concave convex texture 14 cooperates the barb 13 in the caulking groove 12 and makes, has the groove 15 that the multiple tracks equi-spaced apart is provided with formation, fin 11 lower ends can embed caulking groove 12 by base portion 10 sides, making each fin 11 be the firm build-in setting of vertical configuration is arranged on the base portion 10, but and the cooperating of mat barb 13 and groove 15, prevent that fin 11 from upwards emerging in caulking groove 12.In addition, also can give suitable gluing, so that base portion 10 and fin 11 engage more firm with base portion 10 and fin 11 scarfs.Fin 11 adopts spacing P, thickness T and the height H equal proportion of the fin 11 of rabbet joint type design fin 1, and is more unrestricted, can reach H=100T, H=30P, in fact can be unrestricted, therefore can obtain higher density and preferable area of dissipation, with the bigger heat dispersion of performance.

Claims

1. High-density finned heat sink, which is composed of a base and multiple fins. Its characteristics are: there are multiple slots on the base, each slot is provided with at least one protruding barb, and the two sides of the fins are provided with Concave-convex lines are provided to form a concave-convex surface and multiple grooves arranged at equal intervals. The lower ends of the fins can be inserted into the grooves of the base from the side of the base, so that each fin is erected on the base.

2. The high-density fin-type heat sink according to claim 1, wherein there is adhesive glue on the joint between the base and the fin.
