LIGHT-EMITTING DIODE MODULE COOLING SYSTEM Russian patent published in 2014 - IPC G12B15/00 F21V29/00 H05K7/20 H01L23/473 

FIELD: physics, radio.

SUBSTANCE: invention relates to radio electronics and can be used in designing efficient cooling systems of powerful LED modules. The LED module cooling system consists of a heat-removing base merged with a heatsink made of microporous material with microchannels and filled with a liquid coolant and LEDs mounted thereon. The microchannels are located in the heat-removing base under the LEDs perpendicular to the mounting plane of the LEDs, wherein their ends adjoining the LEDs form, in maximum proximity to the p-n junctions of the LEDs, a surface which intensifies boiling and evaporation due to a layer of microporous material deposited between each LED and the end of the adjoining microchannel, wherein the size of the pores of the microporous material is considerably smaller than that of pores of the material filling the heat-removing base of the LED module, wherein the size of the pores of the microporous material decreases towards the LED. The system requires one-time filling with liquid and is less sensitive to variations of the initial volume of the liquid.

EFFECT: providing highly efficient removal of heat from semiconductor LEDs on the surface of the module with minimum heat-transfer resistance.
