This scheme has simple structure, the equipment is convenient, the radiating effect is good, long service life's advantage.

Description

A kind of novel aluminium fin

Technical field

This utility model relates to fin technical field, refers in particular to a kind of novel aluminium fin.

Background technology

Fin is a kind of device dispelled the heat to the easy heat-generating electronic elements in electrical equipment, many by aluminium alloy, pyrite or bronze make tabular, lamellar, splintery etc., in computer, cpu central processing unit to use sizable fin, power supply pipe in television set, line pipe, the power tube in amplifirer will use fin. General fin to be in use coated with last layer heat-conducting silicone grease at electronic component with radiating rib contact surface, makes the heat that components and parts send more effectively be transmitted on fin, is dispersed in surrounding air then through fin. Existing fin is integral structure mostly, and when it produces, die sinking cost is big, and product quality is wayward, can significantly effect to the result of use of radiator.

Summary of the invention

The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of novel aluminium fin.

For achieving the above object, technical scheme provided by the utility model is: a kind of novel aluminium fin, it includes columnar aluminum core, and aluminum core outer peripheral face is set with some pieces of fin, and described heat sink body is square, main center is provided with trepanning, and be sleeved on aluminum core outer peripheral face by trepanning, the main body of trepanning side extends to form heat conduction ring, main body corner is provided with perforation, perforation is four, lays respectively on main body four direction.

Described trepanning adopts interference fit with aluminum core.

Described fin adopts aluminium section bar integral production to shape.

This utility model, after adopting such scheme, adopts aluminum products to utilize conduction of heat and heat radiation, separates reserved certain distance by heat conduction ring, be beneficial to heat radiation between abutting fins, and fin adopts modular construction, convenient processing, die sinking; The advantage that this programme has simple in construction, easy to assembly, good heat dissipation effect, long service life.
