Description
Technical field
The utility model relates to a kind of heat abstractor, relates in particular to a kind of heat abstractor that is specially adapted to the heat radiation of draw and insert-type module.
Background technology
Radiator in the existing central processing unit heat abstractor is the applying degree between raising and the central processing unit, reduce interface resistance between the two, coating one deck heat-conducting cream or install a chill bar (Thermal pad) and increase applying degree between radiator and the heater element on the bottom surface of the pedestal of radiator normally, with the reduction interface resistance, thereby realize good heat conduction and heat radiation.
But, above-mentioned heat abstractor is only applicable to the relatively more fixing electronic component (as central processing unit) that can not pull and push, and when similar heat abstractor is applied in the draw and insert-type module, because the draw and insert-type module may repeatedly pull and push operation, the clean-up performance of its end face is also relatively poor, repeatedly pulling and pushing operation back heat-conducting cream will greatly reduce heat conductivility because of being subjected to polluting, and its in the pasty state the physical characteristic of rapid wear also make it be not suitable for being applied on the heat abstractor of draw and insert-type module.
Chill bar is a kind of rubber-like metal mesh shaped thing, has the stronger capacity of heat transmission, though the influence of the contaminated degree of its heat conductivility is less, and it is the spongiform physical characteristic of square but it can be applied on the draw and insert-type module, but chill bar through the draw and insert-type module long-term pull and push operation repeatedly after, its surface also easily wearing and tearing cause heat conductivility to descend.
As from the foregoing, if existing heat abstractor directly is applied on the draw and insert-type module, obviously there is defective and remains to be improved.
Summary of the invention
Main purpose of the present utility model is, provides a kind of and can prevent the chill bar wearing and tearing, improves applying degree between radiator and the heater element reducing interface resistance, thereby is particularly suitable for being applied in the heat abstractor on the draw and insert-type module.
In order to realize above-mentioned purpose, the utility model provides a kind of heat abstractor, comprises a radiator and a chill bar, and this radiator comprises a pedestal and some radiating fins; This heat abstractor also comprises a heat-conducting plate, and this heat-conducting plate comprises a body and a shell fragment that is convexly equipped with out from this body middle part downwards, and this body is installed on the bottom surface of this pedestal, and this chill bar is housed between the bottom surface and this shell fragment of this pedestal; One end and this body of this shell fragment link together, the other end that this shell fragment is relative be can be movable free end; The both sides of this body bend out one folding piece respectively downwards, and this two tabs support is below this shell fragment free-ended.
This heat abstractor is fixed on the electric connector housing of a draw and insert-type module, and to offering an opening by heat abstractor, this heat abstractor is installed on this opening on this electric connector housing.The heat-conducting plate of this heat abstractor closely amplexiforms mutually with the end face of draw and insert-type module from the opening of this electric connector housing protrudes out the accommodation space of electric connector housing inside, wherein when the draw and insert-type module does not insert electric connector housing as yet, the distance between this shell fragment bottom surface and the electric connector housing bottom surface is less than draw and insert-type module distance between its end face and the electric connector housing bottom surface when inserting.
The utlity model has following beneficial effect, the utility model has additional a heat-conducting plate below chill bar, has played the protection chill bar and has made it not because the operation that repeatedly pulls and pushes of draw and insert-type module causes wearing and tearing and reduces heat dispersion; The shell fragment of this heat-conducting plate has better elastic it can closely be amplexiformed to reduce interface resistance mutually with the end face of this draw and insert-type wireless receiving and dispatching module simultaneously, has good performance of heat dissipation.
