The purpose of this utility model is achieved in that a kind of heat abstractor, and cylinder has outwards extended plural fin in heat radiator central authorities, and the surface of contact of central cylinder below can support the surface that is attached to central processing unit, and is provided with a radiator fan in the heat radiator top; It is characterized in that: be extended with plural helix fin various ways that axial flow wind direction that the anglec of rotation and radiator fan produced adapts, that cold air that radiator fan produces can be simultaneously dispelled the heat to the central processing unit on the circuit board and peripheral electronic original part around the central cylinder of this heat radiator.Wherein:

Be extended with the opposite plural helix fin of axial flow wind direction that the anglec of rotation and radiator fan are produced around the central cylinder of this heat radiator.

Be extended with the identical plural helix fin of axial flow wind direction that the anglec of rotation and radiator fan are produced around the central cylinder of this heat radiator.

The central cylinder of this heat radiator can further be provided with the sealing room, and heat transfer oil is arranged in wherein in sealing room inner filling.

The central cylinder of this heat radiator also can be solid, and the plural helix fin of Yan Shening is upright rotation form all around, and the anglec of rotation of plural helix fin is opposite with the rotation wind direction of radiator fan.

The utility model is owing to being extended with plural helix fin around the heat radiator central authorities cylinder, and plural helix fin top is provided with radiator fan, and the axial flow wind direction that the anglec of rotation of plural helix fin and radiator fan are produced has various ways, cold air that radiator fan produces can be simultaneously dispelled the heat to the electronic original part of central processing unit on the circuit board and periphery, to reach the reduction temperature, improve the central processing unit purpose in serviceable life.

Embodiment

Referring to Fig. 1,2, be embodiment (one), a kind of heat abstractor, be a central cylinder 11 partly in the middle of its heat radiator 1, central authorities' cylinder 11 is inner for being filled with the sealing room 111 of heat transfer oil 113, and central cylinder 11 bottoms are a smooth surface of contact 112, are extended with smoothly shape helix fin 12 of the opposite plural number of axial flow wind direction that the anglec of rotation and radiator fan 2 produced around central cylinder 11.

Penetrate with perforation 21 places of four screws 4 around radiator fan 2 referring to Fig. 3,4,5, this heat radiator 1, be fixed in the gap 121 of helix fin 12, make the bearing 22 of radiator fan 2 be positioned at the top of central cylinder 11, the bottom surface of contact 112 of central cylinder 11 then supports the upper surface of the central processing unit 31 that is affixed on circuit board 3.

After the high hot surface of contact 112 by central cylinder 11 bottoms that is produced during referring to Fig. 5,6, these central processing unit 31 computings enters the sealing room 111 of central cylinder 11, promptly the heat transfer oil 113 by sealing room 111 inside is sent to plural helix fin 12 places of extending around the central cylinder 11 fast, after radiator fan 2 starts, just the axial flow wind direction that is produced because of the sense of rotation and the fan 2 of plural helix fin 12 is reverse direction (as arrow indication among the figure), and what can increase fin 12 holds the wind area; At this moment, the cooling air of radiator fan 2 can be fast inwardly, guiding downwards, and then make cooling air via the exposed surface that blows to bottom center processor 31 in the 121 formed channel sets of plural fin 12 gaps and around electronic component 32 places that set firmly do a heat radiation and use.Because when the utility model dispels the heat, the cooling air of its radiator fan 2 can dispel the heat to all areas of central cylinder 11 and plural fin 12 all around really, and the most cooling air after heat radiator 1 dispelled the heat, just directly concentrate to blow to distribute, its electronic component 32 to central processing unit 31 and periphery is dispelled the heat simultaneously to helix fin 12 bottoms of central cylinder 11 and by 121 places, gap.

Referring to Fig. 7,8,9, be embodiment (two).The anglec of rotation of this helix fin 12 also can meet the rotation wind direction (as Fig. 9 arrow indication) of radiator fan 2, after the high heat that central processing unit 31 is produced enters sealing room 111 by heat radiator 1 bottom surface of contact 112, fast thermal source is conducted to helix fin 12 places of extending around the sealing room 111 by internal heat conductive liquid 113, make cooling air that the radiator fan 2 of heat radiator 1 top blowed via the exposed surface that blows to bottom center processor 31 in the 121 formed channel sets of plural fin 12 gaps simultaneously, the central processing unit on the circuit board 3 31 is done the heat radiation action to concentrate.

Referring to Figure 10,11,12, be embodiment (three), heat radiator 1 central cylinder 11 is a solid, this plural number helix fin 12 is upright rotation form, and the anglec of rotation of plural helix fin 12 is opposite with the rotation wind direction of radiator fan 2, the rotation wind direction that also can meet radiator fan 2, after the high heat that central processing unit 31 is produced can enter the central cylinder 11 of solid setting by heat radiator 1 bottom surface of contact 112, by helix fin 12 places of extending around thermal source is conducted to, the cooling air that the radiator fan 2 of heat radiator 1 top is blowed, via the exposed surface that blows to bottom center processor 31 in the 121 formed channel sets of plural fin 12 gaps, and concentrate central processing unit on the circuit board 3 31 and electronic component 32 are made radiating treatment.

In sum, the structure of the utility model heat radiator can be selected multiple version for use in use, to satisfy different users's demand.
