DEVICE FOR HEAT REMOVAL FROM HEAT-GENERATING OBJECTS Russian patent published in 2016 - IPC G12B15/06 H05K7/20 H01L23/373 

FIELD: heat engineering.

SUBSTANCE: invention relates to heat engineering and can be used for providing heat-generating objects with efficient heat removal, for example, from electronic components, installed on one printed-circuit board in electronic module. Achieved by that, device comprises heat receiving element in form of plate from heat-conducting material with outer surface adjacent to heat-generating object, and heat-removing element in form of plate from heat-conducting material with outer surface adjacent to external heat sink, as well as heat-conducting element arranged between plates tightly to their inner surfaces. At that, heat conducting element is made in form of thermal grease layer, plates are made from flexible heat-conducting foil and equipped with through holes with diameter 0.1-2 mm evenly placed on their area, formation of through holes is performed by alternatively piercing heat-conducting foil from its inner and outer sides, and at through holes outputs produced by piercing, forming projections in heat-conducting foil in form of truncated cone with height of 0.1-2 mm and with generatrix inclination angle of 15°-90°.

EFFECT: technical result is increase of heat removal efficiency.
