The connecting position of the base and the cylinder further forms a curved surface part and a step part, wherein, the curved surface part is inwards concave, forms a circular arc shape and is adjacent to the base, and the step part is adjacent to the cylinder and is parallel to the top face of the base. The radiating fin forms a wave shape and is made of a thin plate which is bent, and the radiating fin is approximately surrounded into a hollow cylinder which is mainly combined on the surrounding surface of the cylinder through materials similar to heat-conducting adhesive.

Description

Heat abstractor

The utility model mainly is about a kind of heat abstractor, and is particularly parallel consistent with the flow direction of air about a kind of orientation of fin, but and the heat abstractor that flows in the smooth arc shape mode of direct air.

Central processing unit is the maincenter of computing machine, and along with the lifting of frequency speed, the heat that counter produced also increases severely thereupon, therefore, as how low-cost, mode solves heat dissipation problem expeditiously, is important topic to be solved in the utility model.

Traditional counter radiating mode is that heat abstractor is flattened on the central processing unit, pedestal by heat abstractor is derived the heat that central processing unit produced, and then heat is distributed by the sheet or the square formation shape fin of heat abstractor, for promoting the convection velocity of air, can increase by a fan again and force air to produce convection current.But these heat abstractors are when increasing fan and produce convection current to force air, and the pedestal of heat abstractor will rebound distinguished and admirable (forming reverse windage), and then cause fully convection current or make the convection velocity reduction of air.Relevant patent please refer to the 5th, 421, No. 406 patents of the 8420174 No. two patent of Taiwan patent or the U.S..

Therefore, how providing a kind of and avoid reverse windage and be beneficial to cross-ventilated heat abstractor, is the problem that the utility model institute desire solves.

Fundamental purpose of the present utility model is to provide a kind of orientation and the parallel consistent heat abstractor of the flow direction of air of fin.

But another purpose of the present utility model is to provide a kind of direct air with the mobile heat abstractor of smooth arc shape mode.

The technical solution of the utility model is achieved in that the utility model heat abstractor mainly is made of radiator and radiating fin, wherein, radiator comprises that a square tabular pedestal and roughly extends and cylindrical cylinder vertically upward along base top surface, be formed with a curved face part and a stage portion in the junction of pedestal and cylinder, wherein curved face part concave and be circular-arc and with the pedestal adjacency, stage portion then is parallel to base top surface and adjacent with cylinder, it is wavy that radiating fin becomes, be roughly to surround a hollow circular cylinder by thin type sheet material bending, it has several fins parallel with the cylinder bearing of trend, and is incorporated into by the material that utilizes similar heat-conducting glue on the cylinder circumferential surface of cylinder.

Owing to adopted technique scheme, the utlity model has advantages such as perfect heat-dissipating, speed be fast.

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

Fig. 1 is the three-dimensional exploded view of the utility model heat abstractor and support chip, fan.

Fig. 2 is the three-dimensional assembly diagram of the utility model heat abstractor and support chip, fan.

Please consult Fig. 1 and Fig. 2 simultaneously, the utility model heat abstractor is made up of radiator 20 and radiating fin 30, and it can install a fan 10 thereon additional by a support chip 40.

Radiator 20 comprises that mainly a square tabular pedestal 21 and roughly extends and cylindrical cylinder 22 vertically upward along these pedestal 21 end faces.The bottom surface of pedestal 21 contacts with heating electronic package (figure does not show), to derive the heat that this electronic package is produced; The top of cylinder 22 also is arranged with a pair of screw 25, in order to when installing fan 10, to utilize (detailed aftermentioned) for support chip 40, junction at pedestal 21 and cylinder 22 is formed with a curved face part 23 and a stage portion 24, wherein this curved face part 23 concaves and is circular-arc, and it is adjacent with pedestal 21, stage portion 24 is then parallel with the end face of pedestal 21, and adjacent with cylinder 22, so that positioning function (detailed aftermentioned) is provided when installing radiating fin 30.This curved face part 23 can make and keep one between stage portion 24 and pedestal 21 end faces suitably apart from d (please refer to Fig. 2), is beneficial to circulation of air (detailed aftermentioned).

30 one-tenth of radiating fins are wavy, be to form and roughly surround a hollow circular cylinder by thin type sheet material bending, it can be bent to form whole hollow circular cylinder by an one monolithic sheet one, also can is bent respectively to form the part of whole hollow circular cylinder and be made up and get (person shown in the figure is bent to form by an one monolithic sheet one) by multi-disc sheet material.This radiating fin 30 utilizes the material of similar heat-conducting glue to be incorporated on the cylinder circumferential surface of cylinder 22, it comprises conduit 34 between passage 31, fin 32, fin folding gap 33 and fin, wherein, the size of this passage 31 cooperates with cylinder 22, and this gap 33 then provides circulation of air with conduit 34.

Be appreciated that ground, radiating fin also can utilize some flat fins to be combined in one by one in the mode of radial arrangement on the cylinder circumferential surface of cylinder 22 except that being bent into wavy and roughly being surrounded the mode of a hollow circular cylinder by above-mentioned thin type sheet material.

Support chip 40 comprises a circular body 45 and a pair of Extendible flake 46 that extends towards external symmetry from body 45 peripheries, in the junction of this body 45 with Extendible flake 46, the screw 25 on corresponding cylinder 22 tops is provided with through hole 42, can with screw 25 this support chip 40 be locked in cylinder 22 tops by making screw 60 pass through hole 42.Near the free end of Extendible flake 46, further be formed with locking hole 44, use (detailed aftermentioned) during fan 10 to provide for installing.

Fan 10 is the convection velocities that are used for promoting air, its position at corresponding support chip 40 locking holes 44 is provided with perforation 12, and pass perforation 12 by screw 50 and fan 10 and support chip 40 can be combined with locking hole 44, with the top of this fan locking at cylinder 22.

During assembling, on the cylinder circumferential surface of cylinder 22, smear earlier the material of similar heat-conducting glue, and then radiating fin 30 is set on the cylinder 22, but this moment this stage portion 24 except that block is located this radiating fin 30, also can make maintenance between this radiating fin 30 and pedestal 21 end faces suitable apart from d.Then, install support chip 40 and fan 10 more successively.

By above-mentioned explanation as can be known, the utility model heat abstractor has following advantage at least:

(1) arrangement of fin 32, gap 33 and conduit 34 forms direction, and is parallel consistent with air-flow direction, the forced convertion that is produced when therefore helping fan 10 starts.

(2) by circular-arc curved face part 23 structures of indent, and between radiating fin 30 and pedestal 21 end faces apart from d, but direct air is mobile with the arrow A direction among second figure.The mode that this kind flows with smooth arc shape, the reverse windage that can avoid pedestal 21 to be caused.
