Abstract
A heat abstractor is used for radiating electronic elements on a circuit board and comprises a radiator attached with the electronic elements, a fan arranged on the radiator, and a cover plate for covering the radiator and the fan, wherein the cover plate is provided with a plurality of vent holes which are arranged above the fan and taken as air inlets when the fan works. In the heat abstractor, the cover plate covers the radiator and the fan, and is provided with the plurality of vent holes which are taken as the air inlets of the centrifugal fan, the vent holes are arranged above the fan, and the heat abstractor can effectively lower the pneumatic noise caused by the work of the fan so as to lower the whole noise caused by the work of the heat abstractor by utilizing the situation that air flows can generate wide-band noise when passing through the vent holes.
Description
Technical field
The present invention relates to a kind of heat abstractor, refer in particular to a kind of heat abstractor that includes fan.
Background technology
Along with vigorously developing rapidly of electronic industry, the application of electronic component more and more widely.The electronic component such as the central processing unit that are installed on the circuit board can produce great amount of heat when operation, heat will cause the electronic component internal temperature increasingly high as not distributing in time, have a strong impact on the stability of electronic component operation.Nowadays heat dissipation problem has become a key factor that influences the computer run performance, also becomes the bottleneck of high speed processor practical application.Therefore, be provided with heat abstractor on the surface of electronic component usually, to reduce the working temperature of electronic component.
Traditional heat abstractor comprises a substrate that is sticked with electronic component and a fins group that is connected with substrate.Sometimes, for improving the radiating efficiency of heat abstractor, heat abstractor also is equipped with fan so that the forced draft that flows to fins group to be provided.Yet, can produce aerodynamic noise during fan work, bring puzzlement to the user.
Summary of the invention
In view of this, be necessary to provide a kind of heat abstractor of the aerodynamic noise that produces fan work can be suppressed the time.
A kind of heat abstractor; Be used for the electronic component that is installed on the circuit board is dispelled the heat; Comprise that the radiator that is sticked mutually with electronic component, the fan and the lid that are arranged on the radiator place the cover plate on radiator and the fan; Offer some air vent holes on the said cover plate, these air vent holes are positioned at the top of said fan, the air inlet with as this fan work the time.
The lid of cover plate described in the said heat abstractor places on radiator and the fan; Offer the air inlet of some air vent holes on this cover plate as centrifugal fan; These air vent holes are positioned at the top of said fan; This heat abstractor can produce the wideband noise when utilizing air communication to cross a plurality of air vent hole, the aerodynamic noise that produces in the time of can reducing fan work effectively, and then the overall noise that produces when reducing said heat abstractor work.
With reference to the accompanying drawings, in conjunction with specific embodiment the present invention is done further description.

Embodiment
See also Fig. 1; Heat abstractor of the present invention is used for the electronic component (figure does not show) that is installed on the circuit board (figure do not show) is dispelled the heat, it comprises radiator 10, be arranged on this radiator 10 centrifugal fan 20 in order to provide to this radiator 10 forced draft, and lid place the cover plate 30 on radiator 10 and the centrifugal fan 20.
Please consult Fig. 2 simultaneously, above-mentioned radiator 10 is made into integration by heat conductivility good metal such as copper, aluminium etc., its bottom surface and the corresponding applying of the end face of electronic component.This radiator 10 comprises substrate 12 and is formed at the some radiating fins 14 on the substrate 12.These radiating fin 14 spaces are provided with, and form a gas channel (not indicating) between every adjacent two radiating fins 14.Said radiating fin 14 is distributed on the said substrate 12 near peripheral region, and these radiating fins 14 surround a holding part 16 on this substrate 12, and is ccontaining in it for said centrifugal fan 20.These radiating fins 14 are radial arrangement with respect to this holding part 16.
Above-mentioned centrifugal fan 20 comprises bearing 22 on the substrate 12 that vertically is arranged at said radiator 10, is placed on magnetic pole 24, installing ring 26 and impeller 28 on the bearing 22.Said impeller 28 is contained in the holding part 16 of radiator 10 and faces with the gas channel of the radiating fin 14 of radiator 10, so that the forced draft that said impeller 28 produces is directly passed radiating fin 14.
Above-mentioned cover plate 30 is a platysome, is processed by heat conductivility good metal such as copper, aluminium etc.This cover plate 30 is corresponding consistent with said radiator 10 on Outside Dimensions.The end face of the radiating fin 14 of the bottom surface of this cover plate 30 and radiator 10 fits, thereby centrifugal fan 20 envelopes are placed in the holding part 16 of radiator 10.In use, this cover plate 30 can be through welding, buckle or directly is incorporated on the radiating fin 14 of radiator 10 with modes such as thermal paste are bonding.The central authorities of said cover plate 30 offer through hole 32, these through hole 32 correspondences be positioned at centrifugal fan 20 impeller 28 directly over.Also offer some air vent holes 34 on this cover plate 30.Even each other, the setting at interval of these air vent holes 34, correspondence is positioned at the top of impeller 28, the air inlet during as centrifugal fan 20 work.These air vent holes 34 are radial arrangement with respect to the through hole 32 of cover plate 30.Be appreciated that ground, the aperture of said air vent hole 34, shape, number can be made reasonable adjustment according to the actual operating position and the result of use of heat abstractor.
In sum; When heat abstractor of the present invention is worked; 14 of the radiating fins that said centrifugal fan 20 is contained in said radiator 10 enclose in the holding part of putting 16; Said cover plate 30 lids place on radiating fin 14 and the centrifugal fan 20, offer the air inlet of some air vent holes 34 as centrifugal fan 20 on this cover plate 30, can produce the wideband noise when utilizing air communication to cross a plurality of air vent hole 34; The aerodynamic noise that produces in the time of can reducing centrifugal fan 20 work effectively, and then reduce the overall noise that produces when said heat abstractor is worked.
