Abstract

The utility model relates to a heat dissipation device, in particular to a heat dissipation device for dissipating the heat of a heating electronic component. The technical scheme is as follows: a heat sink of the heating electronic component comprises heat dissipation needles and a heat dissipation base which are vertical to each other, wherein the heat dissipation needles are uniformly arranged on the heat dissipation base, and the lengths of the heat dissipation needles at two ends are smaller than those of the heat dissipation needles at the inner side, so that more pressure can be borne; two bulges are arranged on each of the heat dissipation needles at the two ends, and the lengths of the heat dissipation needles at the two ends are equal; the lengths of the heat dissipation needles at the inner side are equal, and the two bulges are positioned at the outer sides of the heat dissipation needles; the two bulges and part of the heat dissipation needles between the bulges are coated with insulating paint, and one bulge is positioned at the bottom of the heat dissipation needle; and the connecting line between the electronic components can be positioned between the two bulges. The utility model has the advantages of simple structure, convenience and practicality, and the lengths of the heat dissipation needles at the two ends are shorter than those of the heat dissipation needles at the inner side, so that more pressure can be borne.

Description

A kind of heat-generating electronic elements fin
Technical field
The utility model relates to a kind of heat abstractor, especially a kind of heat abstractor for the heat-generating electronic elements heat radiation.
Background technology
In recent years, along with the transfer capability of power circuit constantly increases, power consumption increases thereupon, and therefore various electronic components have also produced huge heat, have brought heat dissipation problem, have produced heat abstractor thereupon.
Fin is a kind of device of giving the easy heat-generating electronic elements heat radiation in the electrical equipment, how by aluminium alloy, brass or bronze are made tabular, sheet, splintery etc., to use sizable fin as cpu central processing unit in the computer, power supply pipe, line pipe in the television set, the power tube in the amplifirer all will use fin.General fin in use will be coated with the last layer heat-conducting silicone grease at electronic component and fin contact-making surface, and the heat that components and parts are sent is more effective to be transmitted on the fin, goes being dispersed in the surrounding air through fin.But present most fin is owing to the restriction of material, structure etc., easy deformation when bearing bigger pressure.
The utility model content
In order to address the above problem, the utility model has designed a kind of fin for the heat-generating electronic elements heat radiation, and this fin comprises several aciculiform heat radiation pins, and the heat radiation pin length at two ends is shorter than inboard heat radiation pin, therefore can bear bigger pressure.
The technical solution of the utility model is: a kind of heat-generating electronic elements fin, comprise heat radiation pin and heat dissipation base, the heat radiation pin is vertical with heat dissipation base, the heat radiation pin is evenly arranged on the heat dissipation base, the heat radiation pin length at two ends is less than the heat radiation pin length of inboard, can bear bigger pressure like this, two projectioies are respectively arranged on the heat radiation pin at two ends, the equal in length of the heat radiation pin at two ends, inboard heat radiation pin equal in length, two projectioies are positioned at the outside of heat radiation pin, and the heat radiation pin between two projectioies and the projection partly scribbles coatings, a projection in two projectioies is positioned at the bottom of heat radiation pin, the line of electronic component can be positioned between two projectioies.
Advantage of the present utility model is: simple in structure, convenient and practical, the heat radiation pin length at two ends is shorter than inboard heat radiation pin, therefore can bear bigger pressure, and all there are two projectioies in the outside at two ends heat radiation pin, the line of electronic component can be positioned between two projectioies.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, a kind of heat-generating electronic elements fin, comprise two ends heat radiation pin 2, inboard heat radiation pin 5 and heat dissipation base 1, heat radiation pin 2 in two ends is all vertical with heat dissipation base 1 with inboard heat radiation pin 5, two ends heat radiation pin 2 and inboard heat radiation pin 5 are evenly arranged on the heat dissipation base 1, two ends heat radiation pin 2 length are less than inboard heat radiation pin 5 length, can bear bigger pressure like this, projection 3 and 4 two projectioies of projection are respectively arranged on the two ends heat radiation pin 2, the equal in length of two ends heat radiation pin 2, inboard heat radiation pin 5 equal in length, projection 3 and projection 4 are positioned at the outside of two ends heat radiation pin 2, projection 3, heat radiation pin between projection 4 and projection 3 and the projection 4 partly scribbles coatings, and projection 4 is positioned at the bottom of heat radiation pin, the line of electronic component can be positioned between projection 3 and the projection 4.
