Description

The heat abstractor combination

Technical field

The utility model relates to the combination of a kind of heat abstractor, especially relates to a kind ofly can using original design space neatly, satisfies the heat abstractor combination of new radiating requirements.

Background technology

The design of original case radiation as shown in Figure 1, this design be adopt two independently heat abstractor (6,7) be respectively its heat radiation of two heat-generating electronic elements (figure does not show) of its below.And along with the differentiation of product and the specification change of electronic component, the height of the heat abstractor 6 on the left side is owing to the thickness of the CD-ROM drive (scheming not shown) of its top installing will increase, so must reduce the height of heat abstractor 6, cause the area of dissipation of heat abstractor 6 to reduce, and meanwhile the heating power of the heat-generating electronic elements on the left side also will rise to 50 watts from original 45 watts, will cause the heat abstractor 6 on the left side problem of heat-sinking capability deficiency to occur; The heating power of the heat-generating electronic elements on the right then drops to 70 watts from original 85 watts, and will there be the heat-sinking capability surplus in heat abstractor 7.Generally will design heat abstractor again in this case, yet this way can be seriously limited because interior original space layout of cabinet and air-flow distribute.Therefore be necessary to design a kind of space and air-flow that does not need basically to change original design and distribute, but can distribute and adapt to the heat abstractor combination of the radiating requirements of a plurality of heat-generating electronic elements comparatively neatly.

And the heat radiation module shown in No. the 91203420th, Taiwan patent, this is the radiating module of the multiple tubular type heat-transfer superconductive pipe heat conduction of a kind of application, it includes two groups of above fin and the heat-transfer superconductive pipe more than, and this heat-transfer superconductive pipe is combined on the pedestal of this fin, wherein, the pedestal sidewall of fin is drilled with hole, thereby the two ends of this heat-transfer superconductive pipe can be plugged on respectively in the hole of this fin, the heat transferred that is used for a fin is absorbed is to another fin.The radiating module that this patent disclosed also can distribute and adapt to the radiating requirements of a plurality of heat-generating electronic elements comparatively neatly, but because the pedestal of each heat abstractor closely is fixed together with heat pipe, thereby the position between each heat abstractor does not have controllability, and all there are certain manufacturing dimension error in the size of heat abstractor and the position of heat-generating electronic elements when a large amount of production, thereby are difficult to guarantee that the pedestal of each heat abstractor can both closely amplexiform the end face of heat-generating electronic elements.

Above-mentioned existing heat abstractor, existing many disappearances on structural design, and produce trouble and inconvenience in use, remain in fact to be improved.

Technology contents

Main purpose of the present utility model provides a kind ofly can use original design space neatly, satisfies the heat abstractor combination of new radiating requirements.

Embodiment

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

To shown in Figure 7, a kind of heat abstractor combination comprises one first heat abstractor 1 and one second heat abstractor 2 and a location device 3 as Fig. 2.

First heat abstractor 1 is used to installing first electronic component (figure does not show) heat radiation thereunder, and it comprises a pedestal 11, two fixtures 12 and a U-shaped heat pipe 13.The two ends of this two fixture 12 respectively are provided with a stud bolt 121.One end of this U-shaped heat pipe 13 is to be welded on the pedestal 11 of first heat abstractor 1, its other end string is provided with some radiating fins 131, because the heating power of first electronic component drops to the heat-sinking capability surplus that causes original heat abstractor 7 as shown in Figure 1 after 70 watts from original 85 watts, therefore the design is removing the radiating fin of heat abstractor 7 part back formation first heat abstractor 1, these radiating fins 131 are to be suspended at this pedestal 11 tops, form an accommodation space 14 between its bottom and this pedestal 11, also be provided with a through hole 15 at the middle part of first radiating fin 131.

Second heat abstractor 2 is used to installing second electronic component (figure does not show) heat radiation thereunder, comprise that a pedestal 21, some radiating fin 22, a heat pipe 23 and some strings that is extended upward by this pedestal 21 are located at second radiating fin 24 on this heat pipe 23, one end of this heat pipe 23 is fixed on the central authorities of pedestal 21, and its other end string is provided with some second radiating fins 24, and these second radiating fins 24 are that correspondence stretches in the accommodation space 14 that is contained in first heat abstractor 1.This heat pipe 23 can be transmitted to the heat on the pedestal 21 second radiating fin 24 efficiently and distribute, the accommodation space 14 that has effectively utilized first heat abstractor, 1 minimizing area of dissipation and formed, strengthened the heat-sinking capability of second heat abstractor 2, thereby the calorific capacity that has satisfied second heat-generating electronic elements rises to the new radiating requirements that is produced after 50 watts by original 45 watts.Also be provided with four set bolts 26 on the bottom surface of these second heat abstractor, 2 pedestals 21.

This positioner 3 is stamped to form by a sheet metal, which is provided with two installing holes (38,39), and the screw 42 that adopts two correspondences to be installed in the installing hole (38,39) locks to it on second heat abstractor 2.This positioner 3 is positioned between two groups of radiating fins (22,24) of second heat abstractor 2, and extends seven elasticity registration arm (31-37) towards the 24 vertical bendings of second radiating fin.Wherein below positioner 3, be provided with four registration arm (31,32,33,34), each registration arm (31,32,33,34) all is the upper surface that amplexiforms in 1 liang of fixture 12 of first heat abstractor, wherein also be provided with a location hole (311,341) on Wai Ce two registration arm (31,34), this two location hole (311,341) end corresponding respectively and that stud bolt 121 stretches out fixture 12 upper surfaces location of matching; Three elasticity registration arm (35,36,37) are extended in the vertical bending in the middle part of this positioner 3, wherein elasticity registration arm 37 extend in the through hole 15 of radiating fin 131 of first heat abstractor 1, and two other elasticity registration arm (35,36) support is below the radiating fin 131 of first heat abstractor 1, thereby the heat pipe 13 that prevents first heat abstractor 1 bends.

First heat abstractor 1 in this heat abstractor combination is because the radiating requirements decline of first electronic component, thereby thereby radiating fin 131 can reduce area of dissipation and thereunder forms an accommodation space 14, second radiating fin 24 of second heat abstractor 2 then can stretch into and be contained in the accommodation space 14, increase the heat-sinking capability that area of dissipation strengthens second heat abstractor 2, the design has satisfied new radiating requirements on the basis of original design space of applying in a flexible way; And because two heat abstractors (1,2) of this heat abstractor combination are to adopt to combine than the flexible positioner 3 of tool, therefore relative altitude and the position between this two heat abstractor (1,2) can moderately be adjusted, thereby the position deviation that may exist when adapting to actual assembled to cabinet guarantees that two heat abstractors (1,2) of this heat abstractor combination can both closely amplexiform the end face of two heat-generating electronic elements.

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.
