Job stability.Therefore, how to dispel the heat, reduce operating temperature, it is ensured that its stability, increase the service life and to solve at present
Matter of utmost importance.
Common radiating mode is the surface mount fin at heat-generating electronic elements, is quickly inhaled by heat by fin
Receive, and transferred heat away from by its radiating surface, thus reach cooling-down effect.But traditional fin mostly is whole piece, its
Radiating effect is directly proportional to radiating surface, if needing to strengthen radiating effect, then makes the volume of finished product be greatly increased, and installs also
Inconvenient.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model proposes a kind of heat spreader structures, thermal diffusivity is good, and assembling side
Just.
Technical solution of the present utility model is as follows:
A kind of heat spreader structures, including radiator and heat radiation tabletting, attachment screw and square nut, described radiator
Fin is arranged at top, and the centre of lower surface is boss, and this radiator is designed with the logical of fore-and-aft direction in the both sides of described boss
Groove, the intermediate altitude of this groove has laterally wider translot, and this translot is put for described square nut, described heat radiation
Tabletting is the shape that the flat two ends of middle concave fly exhibition, and the two ends flying exhibition respectively have screwing through hole, with the lower end of described radiator
Groove is corresponding, puts into described square nut at described translot, and described screw is by the screw of described heat radiation tabletting
In through hole and the groove of described radiator the square nut described in screwing in, heater is coated on the convex of described radiator
Between the flat region of middle concave of platform and described heat radiation tabletting, described radiator and described heat radiation tabletting are by the good conductor of heat
Make.
Preferably, described boss rectangularity.
Preferably, described radiator and described heat radiation tabletting are formed by aluminium section bar cutting.
Preferably, between described radiator and described heater, also has thermal grease.
Compared with prior art, the beneficial effects of the utility model are:
1, radiator structure is simple, can use section steel cutting, and section bar can be selected to cut by heat radiation power as required
Cut length.
2, heater directly contacts radiator, it is achieved that efficient conduction of heat, heater power brings up to original three times.
3, radiator fastens on circuit boards, and heater pin does not stresses, and circuit board shock resistance is more preferable.
4, radiator can allow heater flow through bigger electric current as current path, and reduce circuit board trace width,
Circuit board is more compact.
