Abstract
The utility model discloses a radiator, comprising a plurality of pony-size aluminum posts which are arranged in an array on an aluminium plate. An open space for installing a semi-conductor device is left in the center of the aluminium plate. Thus, the effective heat dissipation area of the radiator is large, the volume of the radiator can be decreased, and the thermal efficiency can be increased.
Description
The utility model belongs to the radiator for semiconductor product.
Seen in the market radiator is to be raw material by metallic aluminium, is rolled into the section bar radiator for semiconductor with strip heat radiation teeth groove, or with bending to interdigital heat radiator for semiconductor part behind the aluminium plate stamping-out again.Though the radiating effect of these radiators is good, it is bigger than normal that ubiquity volume, the problem that radiating efficiency is on the low side.
The purpose of this utility model provides a kind of radiator, and its volume can be done lessly, has high radiating efficiency simultaneously.
For solving above-mentioned task, solution of the present utility model is, one or both sides at an aluminium sheet are equipped with numerous small size aluminium posts of lining up array, reserve the place that can load semiconductor devices in the central authorities of aluminium sheet and do not adorn the aluminium post, so that semiconductor devices is installed.This radiator in use, the semiconductor devices that is installed on it is wanted the evolution of heat, conducts the heat to each aluminium post by aluminium sheet and gets on, thereby reach radiating effect.
Because in the above-mentioned solution, main radiating piece has adopted numerous small size aluminium posts of lining up array, so with aforesaid existing radiator under identical volume conditions, has much bigger cooling surface area, the radiating efficiency height that has also just shown this radiator, thereby the volume of radiator is reduced, realize the miniaturization of semiconductor circuit structure easily.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the stereogram of radiator;
In Fig. 1, (3) are the circular holes of two stationary semiconductor devices, and (4) are to be the dress vacant lot that semiconductor devices stayed.Numerous aluminium posts (2) of lining up array are fixed on the aluminium sheet (1).Radiator adopts casting moulding to manufacture, and oxidation processes is carried out on the surface.
Claims (4)
1, a kind of radiator that is formed from aluminium is characterized in that: numerous aluminium posts (2) are housed on aluminium sheet (1).
2, radiator according to claim 1 is characterized in that: the central authorities at aluminium sheet (1) leave a vacant lot.
3, radiator according to claim 1 is characterized in that: aluminium post (2) is undersized.
4, radiator according to claim 1 is characterized in that: numerous aluminium posts (2) are lined up array.
