Description

Heat abstractor

[technical field]

The utility model is about a kind of heat abstractor, and is particularly good about a kind of radiating effect, and can avoid the heat abstractor of heat pipe damage.

[background technology]

Along with the quickening of electronic installation internal electronic element arithmetic speed and the increase of consumed power, the heat of corresponding generation also increases severely thereupon, for electronic component can be operated under normal working temperature, need to set up a radiator usually and in time discharge the heat that electronic component produces at electronical elements surface.

Heat abstractor commonly used is a lot, and major part is an aluminium extruded type, such heat abstractor is got by the extrusion molding of aluminum or aluminum alloy one, it generally includes pedestal and reaches by the extended some radiating fins of base top surface one, this pedestal is fitted in electronical elements surface, absorbing the heat that electronic component produces, and this heat transferred is distributed to these radiating fins.But this class aluminium extruded type heat abstractor commonly used is made by aluminum or aluminum alloy, and its heat conductivility is limited, is difficult to fully be delivered to the heat that electronic component produces on the radiating fin and distribute fast; And, this class heat abstractor makes in the extrusion molding mode, the height of radiating fin will be influenced by mould and manufacturing technology level and certain limit will be arranged, and correspondingly just cause the integral heat sink surface area of radiator to be restricted, and be difficult to meet the radiating requirements of high power electronic element now.

For this reason, industry is used the heat-pipe radiator combination instead and is fully distributed fast the heat that electronic component produces, the combination of this kind heat-pipe radiator is made up of heat-collecting block, heat pipe and some radiating fins, and wherein these radiating fins directly are installed in heat pipe outer wall by the method for welding or punching press.But the pipe thickness of heat pipe is generally 3-5mm, and this heat-pipe radiator commonly used is combined in the installing radiating fin on heat pipe the time, very easily causes the heat pipe distortion, makes its inner capillary structure destroyed, thereby causes heat-conductive characteristic to descend.

[summary of the invention]

The purpose of this utility model is to provide a kind of radiating effect good, and can avoid the heat abstractor of heat pipe damage.

The purpose of this utility model is achieved through the following technical solutions: the utility model heat abstractor has a heating column, run through on this heating column and be welded with a heat pipe, the shaft outer wall of this heating column is equiped with some radiating fins, the central authorities of each radiating fin offer a through hole, the periphery of this through hole extends outward a lug, be fitted in the shaft outer wall of heating column with punching press, and form gas channel between the adjacent radiating fin; A fan retaining element is respectively installed in the appropriate position at these heating column two ends, the intrinsic fan of a side chain of its corresponding gas channel; One end of this heating column is by the mode and a substrate interference fit of punching press, and a surface and the heat-generating electronic elements of this substrate are fitted, to absorb the heat that electronic component produces.

Compared with prior art, the utility model heat abstractor is welded on heat pipe on the heating column, and radiating fin is the shaft outer wall that punching press is fitted in this heating column, therefore can not damage heat pipe.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is further described.

[embodiment]

Please together consult Fig. 1 to Fig. 3, the utility model heat abstractor has a heating column 10, run through on this heating column 10 and be welded with a heat pipe 20, the shaft outer wall of this heating column 10 is equiped with some radiating fins 30, these radiating fins 30 roughly are "  " shape, and the central authorities of each radiating fin 30 offer a through hole 32, and the periphery of this through hole 32 extends outward a lug 34, be fitted in the shaft outer wall of heating column 10 and assist heat radiation with punching press, and form gas channel 36 between the adjacent radiating fin 30; Outwards protrude at the two ends of this heating column 10, and wherein an end is by the mode and a substrate 40 interference fit of punching press, and fit with heat-generating electronic elements (figure does not show) in a surface of this substrate 40, to absorb the heat that electronic component produces.

A fan retaining element 50 is respectively installed in the appropriate position at these heating column 10 two ends, this fan retaining element 50 has a panel-shaped base body 52, one lateral margin two ends of these matrix 52 corresponding gas channels 36 bend out a stator 54 respectively, and this stator 54 is provided with a screw 56 with locking fan 60.
