DEVICE FOR COOLING SINGLE POWERFUL LED WITH INTENSIFIED CONDENSATION SYSTEM Russian patent published in 2017 - IPC F21V29/51 F21V29/71 F21V29/83 H01L33/64 

FIELD: electricity.

SUBSTANCE: in the cooling device of a single powerful LED with an intensified condensation system including a base with the LED, a steam channel adjoins the surface of the base, which forms the intensifying heat exchange surface in the closest proximity to the p-n-junctions of the LED. A radiator is made of a closed thin-walled corrugated sheet profile in the form of a multiblade drum. The radiator blades have rounded vertices with a radius of curvature, r, lying in the range 0.25×k≤r≤1×k, where k is the capillary heat carrier constant, the channels between the radiator blades have a constant width and rounded bases, the radii of the blades' vertices are 2-3 times as much as the radii of the channels' bases.

EFFECT: high-efficiency heat dissipation with a minimum value of heat transfer resistance from a single semiconductor LED.
