Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figures 2 and 3, a kind of heat abstractor 1, be installed in and be a chip 5 heat radiations on this circuit board 2 on the circuit board 2, this circuit board 2 respectively offers an installing hole 21 around this chip 5, and respectively be provided with a reference column 41 in the both sides of this chip 5, one end of this reference column 41 is bigger cylinder 411, and the other end is slightly little cylinder 412.

This heat abstractor 1 comprises a radiator 10, four fixtures 3 and two positioners 42.This radiator 10 comprises a pedestal 11 and the some radiating fins 12 that extend upward from this pedestal 11.The pedestal 11 of this radiator 10 is a heat-conducting plate (Vapor Chamber), the inside of this pedestal 11 be hollow and be filled with the water vapour drop, these drops are vaporized after heat absorption, make this pedestal 11 have the very strong capacity of heat transmission.Four jiaos of the pedestal 11 of this radiator 10 respectively offer an installing hole 111, and respectively offer a through hole 13 in the both sides of pedestal 11.These fixtures 3 are to be installed in the installing hole 111 of radiator 10, each fixture 3 comprises a set bolt 31, one is set in a spring 32 and the retainer ring 33 on the set bolt 31, this retainer ring 33 is set in the lower end of this set bolt 31, replaces to prevent that below this pedestal 11 this set bolt 31 from deviating from installing hole 111.Circuit board 2 among the design is to have diverted from one use to another employed circuit board in the previous design, the height of the reference column 41 in the previous design is lower, can not project in the through hole 13 of pedestal 11, therefore be necessary in through hole 13, to install positioner 42 additional, can bring into play the effect of location thereby this reference column 41 is matched with positioner 42.

To shown in Figure 8, this two positioner 42 is to be installed in the through hole 13 of radiator 10 both sides as Fig. 5, and each positioner 42 comprises a body 421 and the two resilient clamp portions 422 and two stop sections 423 that extend out from an end of body 421.The body 421 of this positioner 42 is one to be the cylinder of cylindric hollow, and its middle part surrounds and is formed with a circular hole 4216.This two resilient clamp portion 422 comprises two button gripping arms 4221 that extend upward from body 421 and two lugs 4222 that outwards protrude out on the gripping arms 4221 from two buttons respectively.This two stop section 423 is two prominent arms that the upside from body 421 outwards bends out.

This two positioner 42 is that the below from these radiator 10 pedestals 11 is encased in the through hole 13 of radiator 10, after two button gripping arms 4221 of this positioner 42 are passed the through hole 13 of these radiator 10 pedestals 11 from the bottom to top, the upside that these two lugs, 4222 elastic return are replaced at this radiator 10 pedestals 11 can't oppositely withdraw from this two buttons gripping arm 4221 downwards, the downside that this moment, this two stop section 423 was then replaced at these radiator 10 pedestals 11 can't further move upward this two buttons gripping arm 4221, thereby this positioner 42 is fixed on the radiator 10.

As shown in Figure 4, when this heat abstractor 1 is attached to circuit board 2, two reference columns, 41 correspondences on the circuit board 2 are inserted in the circular hole 4216 of two positioners 42, this moment is because the matching relationship between two positioners 42 of two reference columns 41 of circuit board 2 and heat abstractor 1 has been determined the position relation of circuit board 2 with heat abstractor 1, just not circuit board 2 left and right sides slippages relatively again of this radiator 10 when therefore tightening set bolt 31 with screwdriver again, made things convenient for the installing hole 21 on the alignment circuit plate 2 to tighten set bolt 31, radiator 10 has been locked on the circuit board 2.

Only adopted two positioners 42 and two reference columns 41 in the present embodiment, accurate in locating more such as three-point fix, also can increase reference column 41 on circuit board 2 if desired, simultaneously corresponding increase positioner 42 on radiator 10.

The above; only be the preferable feasible embodiment of the utility model; can not therefore promptly limit to interest field of the present utility model; concerning being familiar with those of ordinary skill in the art; such as use the technical solution of the utility model and technical conceive to make other various corresponding changes and distortion, and all these changes and distortion all should belong in the protection range of the utility model claim.
