Abstract

A radiator is provided, which comprises a plurality of radiation fins, three heat exchange tubes and a pedestal, wherein the each fin is arranged thereon with a three-way through-hole and a plurality of raised and concave portions, the raised and concave portions being arranged alternately on the two sides of the through-hole. The heat exchange tubes, on one end, are inserted into the through-hole and closely engaged to one another, and fixed on the pedestal on the other end. The pedestal is attached to electronic components to absorb the heat produced by the electronic components, and the heat is transferred to each radiation fin by the heat exchange tubes and then dissipated.

Description

Radiator

[technical field]

The utility model is about a kind of radiator, refers in particular to a kind of radiator that can distribute the heat of electronic component generation fast, fully.

[background technology]

Many electronic components the time can produce a large amount of heats in operation, if untimely heat is discharged, and the stability when influence electronic component and move.For this reason, industry is installed a radiator at electronical elements surface usually, is used for heat is discharged as early as possible.

Existing radiator major part is made up of fin, heat pipe and pedestal, wherein be equipped with through hole on each fin, utilize this through hole each fin to be located in an end of heat pipe, and the other end of heat pipe is fixed on the pedestal, pedestal is to be fitted on the electronic component, be used for absorbing the heat that electronic component produces, and utilize heat pipe that heat transferred is distributed to each fin.Yet the fin surface of this radiator is the plane, and its area of dissipation is little, and is difficult to form flow-disturbing between each fin, greatly reduces radiating effect, is difficult for distributing fast, fully the heat that electronic component produces.

[summary of the invention]

The purpose of this utility model is to provide a kind of radiator, has some protuberances and recess on its fin, to distribute the heat that electronic component produces fast, fully.

The purpose of this utility model is achieved through the following technical solutions: the utility model radiator comprises several cooling fins, at least one heat pipe and a pedestal.Wherein all be provided with a through hole and some protuberances, recess on each fin at least, these protuberances and recess are the both sides that alternately are arranged in through hole.One end of heat pipe is in the corresponding through hole that inserts fin and realizes closely cooperating that its other end then is to be fixed on the pedestal.This pedestal is to be fitted in to absorb the heat that electronic component produces on the electronic component, and by heat pipe heat transferred is distributed to each fin.

Owing to adopted technique scheme, the fin of the utility model radiator is provided with some protuberances and recess, has so not only increased area of dissipation, and when cold air enters, forms flow-disturbing between each fin, has strengthened radiating effect.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]

Please refer to Fig. 1 to Fig. 3, the utility model radiator 1 is to be used for distributing the heat that electronic component (figure does not show) produces, and it mainly comprises some fin 10, three heat pipes 20 and a pedestal 30.

The corresponding mutually all rows of these fin 10 central authorities are provided with and are used for for three heat pipes, 20 corresponding three through holes 11 that intert, each through hole 11 periphery all extends a junction surface 12 in the same way, this junction surface is to engage with heat pipe 20 outer walls, be used for increasing the contact area of 10 of heat pipe 20 and fin, also make 10 of each fin keep certain distance simultaneously; 12 directions vertically bend out a flanging 13 towards the junction surface respectively for the top side of these fin 10 and bottom side, and the flanging 13 of a fin 10 is the back side of replacing at another fin 10 in adjacent two fin 10, makes these fin 10 be combined to form the box body of a both-side opening.The both sides of these through holes 11 alternately are arranged with some protuberances 14 and recess 15 respectively, be used for increasing the area of dissipation of fin 10, when cold airflow blows side fashionable by the box body one that these fin 10 are combined to form, these protuberances 14 and recess 15 will make cold airflow produce flow-disturbing 10 of fin, the increase cold airflow contacts with fin 10, thereby improves radiating effect.One end of these heat pipes 20 inserts in the fin 10 corresponding through holes 11 respectively successively and realizes fluid-tight engagement, and its other end is to be fixed on the pedestal 30.This pedestal 30 is to be fitted in to absorb the heat that electronic component produces on the electronic component, and the heat that this pedestal 30 absorbs is delivered to each fin 10 by heat pipe 20 and distributes.
