Abstract

The utility model relates to a heat radiator, which comprises a heat radiating body and a basal body, wherein, the heat radiating body mainly comprises a cylindrical body and a plurality of fins radially and outwards extending from the cylindrical surface of the body in a radial shape, the body penetrates and forms a cylindrical through hole along the central axial line of the body, and grooves are formed among a plurality of radial fins to be used for the circulation of air. The basal body mainly comprises a disk-shaped base and a cylindrical column body approximately, vertically and upwards extending from the top surface of the base, the column body is inserted in the through hole of the heat radiating body, the bottom surface of the base is contacted with a heating electronic component, and the connecting position of the base and the column body is provided with a part of which the concave arc-shaped curved surface is connected with the base and the top surface of the part is close to the column body and is opposite to the base in parallel.

Description

Heat abstractor

The utility model mainly is about a kind of heat abstractor, and is particularly firm and have a heat abstractor of great heat radiation effect about a kind of easy to manufacture, overall structure.

Central processing unit is the computer maincenter, and along with the lifting of speed, the heat that it produced is also along with increase, and therefore as how low-cost, high efficiency mode solves heat dissipation problem, is important topic to be solved in the utility model.

Traditional radiating mode is a lot, as No. 82211477 announcement of Taiwan patent application a kind of heat abstractor is arranged, please refer to Fig. 1, this heat abstractor 1 comprises a base 11 and some fins 10, this fin 10 is directly to be inserted on base 11 end faces in the formed groove 12, and base 11 bottom surfaces are to contact with central processing unit (figure does not show).Therefore, this heat abstractor needs some fins 10 are inserted in the groove 12 of base 11 one by one, and it is quite complicated to make formality, and the combining also built on the sand of this fin 10 and 11 of bases, and fin 10 very easily produces and rocks situation.In addition, this fin 10 is directly to be inserted in the groove 12 of base 11, very easily produces the space between the contact surface of fin 10 and base 11, thereby influences the integral heat sink effect widely.

Therefore, how providing the heat abstractor that a kind of radiating effect is good, easy to manufacture and overall structure is firm, is problem to be solved in the utility model.

The utility model purpose is to provide the heat abstractor that a kind of radiating effect is good, easy to manufacture and overall structure is firm.

The technical solution of the utility model is: the utility model heat abstractor mainly is made of radiator and matrix, wherein radiator comprises a cylindrical body and some fins from the radial extension of this body periphery radial outward, this body runs through along its central axis and is formed with a cylindric through hole, and is formed with groove for circulation of air between some radial fins.This matrix mainly comprises the cylindric cylinder that a disc-shaped base and is roughly extended vertically upward from this base top surface, the through hole interference engagement of this cylinder and radiator, and base bottom surface contacts with the heating electronic building brick.Be provided with a step in the junction of this pedestal and cylinder, this step is that the arc curve with indent is connected with pedestal, and its end face is in abutting connection with cylinder and parallel relative with pedestal.

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

Be further described this use is novel in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the stereogram of traditional heat-dissipating device.

Fig. 2 is the three-dimensional exploded view of the utility model heat abstractor.

Fig. 3 is the three-dimensional combination figure of the diffusing heat abstractor of the utility model.

Please consult Fig. 2 and Fig. 3 simultaneously, the utility model heat abstractor is made up of radiator 20 and matrix 30, and wherein this radiator 20 is directly to be extruded by aluminum metal to form, and matrix 30 is then made by the copper metal, takes into account simultaneously and makes and radiating effect.

Radiator 20 mainly comprises a cylindrical body 25 and some fins 21 from the radial extension of these body 25 periphery radial outward, this body 25 runs through along its central axis and is formed with a cylindric through hole 22, and this through hole 22 is to accommodate the cylinder 31 of matrix 30 in wherein (seeing below) in order to interference engagement.Be formed with groove 24 for circulation of air between these the some radial fins 21, and, when extruding, be formed with the fitting recess 23 that slightly is the C font in the lump, utilize when (figure shows) for the installing fan at the extending end of specific fin 21.

Matrix 30 is to make with the copper metal turning, mainly comprise the cylindric cylinder 31 that a disc-shaped base 32 and is roughly extended vertically upward from these pedestal 32 end faces, through hole 22 interference engagement of this cylinder 31 and radiator 20, and pedestal 32 bottom surfaces contact with heating electronic building brick (figure does not show), and the heat that electronic building brick produces is derived.Junction at this pedestal 32 and cylinder 31 is provided with a step 33, and this step 33 is that the arc curve 35 with indent is connected with pedestal 32, and its end face 34 is in abutting connection with cylinder 31 and parallel relative with pedestal 32.

During assembling; cylinder 31 interference engagement of matrix 30 are inserted in the through hole 22 of radiator 20; in this process; the radiator of being made by aluminum metal 20 has that the part material will be extruded and tight contact of further guaranteeing matrix 30

cylinders

31 and 22 of radiator 20 through holes; and the end face 34 of this step 33 locatees block for radiator 20 so that keep suitable distance between radiator 20 and matrix 30 pedestals 32, and this arc curve 35 then is beneficial to flowing of air.
