FIELD: physics.
SUBSTANCE: intensified cooling system of a single high-power LED consists of a heat-conducting base that forms, in the closest proximity to the p-n transition of the LED, a heat exchange surface intensified by radial finning made in the form of microchannels of triangular cross section with an LED on it. To the heat-conducting base, on the side of the intensifying surface, a heat pipe is connected, filled with 20-25% of heat carrier so that the condensation region is above the evaporation region and the coolant flows into the heating zone under the influence of gravity.
EFFECT: providing high-efficiency heat removal with a minimum value of heat transfer resistance from a single high-power LED.
