This scheme has simple structure, the equipment is convenient, the radiating effect is good, long service life's advantage.
Description
Technical field
This utility model relates to heat sink technology field, refers in particular to the radiator of a kind of transistor.
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 the simple in construction of a kind of transistor, easy to assembly, good heat dissipation effect, long service life radiator.
For achieving the above object, technical scheme provided by the utility model is: the radiator of a kind of transistor, it include present a theatrical performance as the last item on a programme, fin, wherein, present a theatrical performance as the last item on a programme as square, present a theatrical performance as the last item on a programme top and bottom has all convexed to form boss, boss center is provided with counterbore; Side of presenting a theatrical performance as the last item on a programme is provided with two heat radiation axles being parallel to each other, heat radiation axle is set with some pieces of fin, described heat sink body is rectangle, main center is provided with trepanning, and it is sleeved on heat radiation axle by trepanning, the main body of trepanning side extends to form heat conduction ring, between abutting fins, is separated to form radiating area by heat conduction ring.
Described heat radiation shaft end adopts spherical transition.
Described trepanning is two, is distributed along its length on a heat sink.
Described corner of presenting a theatrical performance as the last item on a programme all adopts arc rounding off, and its corner is provided with fixing hole.
Described sidewall of presenting a theatrical performance as the last item on a programme is provided with axis hole, and heat radiation axle one end is sleeved in axis hole, and the other end is unsettled to be connected with fin.
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.
