Abstract

The utility model discloses a radiating device which comprises a base, a fan placed on the base, and a radiating fin group, wherein the radiating fin group includes a plurality of radiating fins which enable the fan to be encircled in the middle thereof and are radially arranged around the fan, and the radiating fins are fixed on the base. Each radiating fin is provided with a plurality of through holes, of which one ends are arranged on one side, connected with the base, of the radiating fin and the other ends are arranged on the other side opposite to the side and connected with the base. Therefore, when the fan runs, hot air takes heat out under a flow guide role of the through holes. Compared with the prior art, the radiating device has the following beneficial effects: heat generated during working of electronic components is transmitted and radiated through the radiating fins, the through holes thereof and a heat pipe, the radiating efficiency is improved, and the service life of the electronic components is effectively prolonged.

Description

Heat abstractor

Technical field

The utility model relates to a kind of heat abstractor, relates in particular to a kind of heat abstractor with high heat conduction efficiency.

Background technology

Along with the electric crystal quantity in electronic component unit are increases, the heat energy producing while causing its work also increases relatively, and the operating frequency of electronic component is more and more higher, and the heat that during electric crystal work, switch transition causes also increases greatly.

In recent years, due to the fast development of manufacture of semiconductor and IC encapsulation technology, the computational speed of wafer significantly promotes, and makes its heat energy increase, if fail to discharge in time heat, causes wafer arithmetic speed to reduce, and affects the wafer life-span.

Utility model content

The utility model proposes a kind of heat abstractor, to solve at present, because heat in electronic component promotes, fail to discharge in time the technical problem outside element.

The utility model adopts following technical scheme to realize: a kind of heat abstractor, and it comprises: pedestal; Be positioned over the fan on pedestal; And groups of fins, comprise that several make fan be located in the radial fin around fan arrangement that is wherein, described fin is fixed on this pedestal, and on each fin, be provided with some through holes, described through hole one end is opened in the side that this fin and pedestal connect, the other end is opened in another opposite flank connecting with pedestal, and with when fan operates, the guide functions of hot blast via through holes is taken heat out of.

Preferably, the utility model provides a kind of heat abstractor, and wherein, described heat abstractor also comprises heat pipe, and described heat pipe is arranged between this pedestal and this groups of fins.

Preferably, the utility model provides a kind of heat abstractor, and wherein, described fin is made by aluminum, and pedestal and heat pipe are copper product.

Preferably, the utility model provides a kind of heat abstractor, wherein, is provided with for heat pipe and embeds groove wherein on described pedestal.

Compared with prior art, the utlity model has following beneficial effect: the heat producing carries out heat loss through conduction, has improved radiating efficiency, has effectively extended the life-span of electronic component when fin and through hole thereof and heat pipe are worked electronic component.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model one embodiment heat abstractor.

Embodiment

Please refer to shown in Fig. 1, is the structural representation of the utility model one embodiment heat abstractor.The heat that the utility model produces when fin and through hole thereof and heat pipe are worked electronic component carries out heat loss through conduction, has improved radiating efficiency, has effectively extended the life-span of electronic component.

Wherein, described heat abstractor 10 comprises: pedestal 101; Be positioned over the fan 102 on pedestal 101; Groups of fins 103 and heat pipe (not shown).

Again, described groups of fins 103 mainly comprises several fin 1031, described fin 1031 is radial and arranges and fan 102 is located in wherein around fan 102, described fin 1031 is fixed on this pedestal 101, and on each fin 1031, be provided with some through holes 10311, described through hole 10311 one end are opened in the side that this fin 1031 and pedestal 101 connect, these through hole 10311 other ends are opened in another opposite flank connecting with pedestal 101, this through hole 10311 runs through this fin 1031, with when fan 102 operates, the guide functions of via through holes 10311 is taken heat out of.

Moreover described heat abstractor 10 also comprises heat pipe, described heat pipe is arranged between this pedestal 101 and this groups of fins 103, on described pedestal 101, is provided with groove (not shown), and this groove embeds wherein for heat pipe.

In the present embodiment, described fin 1031 is made by aluminum, and described pedestal 101 and heat pipe are copper product, and fin 1031 quality that aluminum is made are light, and the pedestal 101 of identical material is combined with heat pipe, is beneficial to increase pyroconductivity.

Due to the setting that is mutually sticked of electronic component (not shown) and pedestal 101, heat on electronic component is passed to heat pipe and fin 1031 through copper pedestal 101, when fan 102 comes into operation, with the hot blast of heat under the drive of fan 102 by running through the through hole 10311 of fin 1031, directly discharge this heat abstractor 10, reach the object of quick heat radiating.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
