Abstract

The utility model discloses heat radiation fins, and belongs to the heat radiation device field. The heat radiation fins include upper fins and a pedestal. The two sides of each upper fin are provided with L-shaped parts. The middle of the upper end of the pedestal is provided with concave buckles. The concave buckles are buckled on the lower ends of the upper fins, so the upper fins are riveted on the pedestal. The heat radiation fins are stable in structure and are excellent in heat radiation effect.

Description

Radiating fin

Technical field

The utility model relates to the heat abstractor field, particularly relates to radiating fin.

Background technology

At present, the use of radiating fin is more and more extensive, and many precise electronics or electrical equipment all need to use radiating fin and dispels the heat.General radiating fin comprises fin and base, and the connected mode of upper fin and base is generally welding, and such connected mode complex procedures, production efficiency are not high, and easy sealing-off, and quality can not be guaranteed.Therefore, we must carry out structural improvement to radiating fin.

The utility model content

For addressing the above problem, the utility model provides radiating fin, and stabilized structure is difficult for sealing-off.

Technical solution adopted in the utility model is: radiating fin, comprise fin and base, and both sides, upper fin lower end are provided with the L-type parts, and base is provided with the matrix button in the middle of the upper end, and the matrix button is fastened on the fin lower end is riveted together fin and base.

In technique scheme, radiating fin also comprises button Fin, and is spaced apart and be fixed together each fin of upper fin.

In technique scheme, matrix button both sides are provided with one or more projections, and both sides are provided with one or more grooves corresponding with projection in the upper fin, and projection and recess-mounted are together.

The beneficial effects of the utility model are: the radiating fin of above-mentioned structure, the matrix button is fastened on the fin lower end and fin is connected with base connect, the sealing-off problem can not occur, and has increased upper fin and base contact area, increase the coefficient of overall heat transmission, radiating effect is better.Generally speaking, the utility model stabilized structure, good heat dissipation effect.

Among the figure, 1, upper fin; 11, L-type parts; 2, base; 3, matrix button; 4, button Fin.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 to 4 figure has schematically shown the radiating fin according to a kind of execution mode of the present utility model.

This radiating fin comprises fin 1 and base 2, and both sides, upper fin 1 lower end are provided with L-type parts 11, is provided with matrix button 3 in the middle of base 2 upper ends, and matrix button 3 is fastened on fin 1 lower end is riveted together fin 1 and base 2.This radiating fin also comprises button Fin4, and is spaced apart and be fixed together upper fin 1 each fin.

In assembling, when fin 1 and base 2, utilize punch die to push matrix button 3 downwards.The groove two ends projection of matrix button 3 can owing to making the elasticity of material, can make matrix button 3 block fin 1 lower end to the both sides extruding, and fin 1 and base 2 are firmly linked together.

In some embodiments, matrix button 3 both sides respectively are provided with one or more projections, and upper fin 1 interior both sides respectively are provided with groove corresponding to one or more and projection, and projection and recess-mounted make fin 1 be connected connection with base more firm together.

Above embodiment just is explanation rather than restriction the utility model, therefore all equivalences of doing according to the described method of the utility model patent claim change or modify, is included in the utility model patent claim.
