Abstract

The utility model relates to a radiator. The utility model comprises a base and a radiating fin body, wherein, the radiating fin body is made of metal sheets which are continuously bent and are fixed on the base by heat conducting gum; the base is made of a metal plate which has specific thichkness and is bent into the shape of U and provided with a thick bottom plate and a pair of thin side plates, both side edges of the thick bottom plate are perpendicularly and upwards extended to form the two thin side plates, and the thick bottom plate and the thin side plates form a space which is used for containing the radiating fin body. The utility model utilizes the thick bottom plate of the radiator to contact the top surface of the central processing unit to quickly and effectively conduct the quantity of heat generatd by the central processing unit, and the quantity of heat is exhausted by the radiating fin body.

Description

Heating radiator

The utility model is about a kind of heating radiator, is meant a kind of have collapsible radiating fin and the good heating radiator of radiating effect especially.

Along with developing rapidly of computing information industry, the arithmetic speed of computer cpu is more and more faster, and the heat that it produced is also more and more, and too much heat is if can't in time discharge, the stability when having a strong impact on the central processing unit operation.Therefore, industry is installed the assembly that an aluminium extruded type heating radiator adds fan at the central processing unit end face usually, to assist to discharge heat.But, usually the aluminium extruded type heating radiator known to is because of processing procedure and manufacturing technology cause, the ratio of groove width can only reach 13: 1 at most between its radiating fin height and radiating fin, its radiating effect that can realize is difficult to realistic user demand, and increase along with the central processing unit thermal value, the volume of the aluminium extruded type heating radiator usually also needs corresponding increasing improving radiating effect, and this just causes the increase of heatsink weight and manufacturing cost, and fixing problem such as difficulty.

For solving many shortcomings of above-mentioned aluminium extruded type heating radiator, so industry adopts a kind of combined radiator that is combined on the pedestal by collapsible radiating fin to improve.But, this class combined radiator can't install fan usually additional increases radiating effect in the forced convertion mode, but increase radiating effect in the natural convection mode, so radiating effect is not good, and the pedestal of this type of combined radiator is normally made by the sheet metal punching press, can't fast and effeciently conduct the heat that central processing unit produces, so be difficult to realistic user demand.In addition, the collapsible radiating fin of this type of combined radiator is also formed by sheet metal bending, therefore if when being fixed on fan on the radiating fin, very easily causing the flexural deformation of radiating fin, thereby influences radiating effect.Correlation technique can be with reference to No. the 85214927th, Taiwan patented claim.

Therefore, how providing the heating radiator that a kind of heat conductivility is good and can dispel the heat in conjunction with forced convertion, is problem extremely to be solved really.

The purpose of this utility model is to provide a kind of heat conductivility good and can carry out the heating radiator of auxiliary heat dissipation in conjunction with forced convertion.

For achieving the above object, the utility model has adopted following technical scheme: the utility model heating radiator comprises a pedestal and a radiating fin.Wherein, this radiating fin by sheet metal continuously bending form and be fixed on the pedestal by heat-conducting glue etc., this pedestal is bent into the U font and is had a thicker base plate and a pair of thin side plate by the sheet metal of specific thicknesses design, and this is extended and formed jointly the space of ccontaining this radiating fin vertically upward by the base plate both side edges to thin side plate.

Compared with prior art, the pedestal of the utility model heating radiator is formed by the sheet metal bending of specific thicknesses design, thicker base plate by heating radiator contacts the central processing unit end face, can fast and effeciently conduct the heat of central processing unit generation and distribute discharge, and can carry out auxiliary heat dissipation in conjunction with forced convertion simultaneously by this radiating fin.

Below in conjunction with accompanying drawing embodiment of the present utility model is specifically described:

Fig. 1 is the three-dimensional exploded view of the utility model heating radiator.

Fig. 2 is the three-dimensional combination figure of the utility model heating radiator.

Fig. 3 is the three-dimensional combination figure of another embodiment of the utility model heating radiator.

Please together consult Fig. 1 and Fig. 2, the utility model heating radiator 3 comprises a pedestal 2 and a radiating fin 1.Wherein, this radiating fin 1 by sheet metal continuously bending form and be fixed on the pedestal 2 by heat-conducting glue (scheming not show) etc., this pedestal 2 is bent into the U font and is had a thicker base plate 22 and a pair of thin side plate 24 by the sheet metal of specific thicknesses design, and this is extended and formed jointly the space of ccontaining this radiating fin 1 vertically upward by base plate 22 both side edges to thin side plate 24.Thicker base plate 22 by heating radiator 3 contacts central processing unit (figure does not show) end face, can fast and effeciently conduct the heat of central processing unit generation and distribute discharge by this radiating fin 1.Though it is integrally formed to be appreciated that the radiating fin 1 of the utility model heating radiator 3 is bent continuously by sheet metal, uses the some metal plates that are arranged in parallel with each other basically (figure does not show) instead, also can reach similar effect.

See also Fig. 3 again, it is the three-dimensional combination figure of another embodiment of the utility model heating radiator.Wherein, the biside plate 24 ' of this heating radiator 3 ' pedestal 2 ' inwardly vertically extends a lug 26 ' respectively at the place, diagonal angle, and this lug 26 ' is parallel to the base plate 22 ' of pedestal 2 ' and is positioned at the top, top of radiating fin 1 '.Be respectively equipped with a button hole 28 ' on each lug 26 ', fixing for a fan (figure do not show) installing, by the installing of fan, can form forced convertion and promote radiating effect.
