CASCADE LIGHT-EMITTING THERMOELECTRIC UNIT Russian patent published in 2014 - IPC G12B15/06 H01L23/34 H01L23/38 H05K7/20 G06F1/20 

FIELD: heating.

SUBSTANCE: light-emitting thermomodules are used. A light-emitting thermomodule allows reducing parasite conductive transfer from the hot junction side, which is heated not as mush as that due to the fact that some part of energy is taken away in the form of an emission, and it is not converted to heat on the hot junction. Reduction of heat transfer by conduction between hot and cold junctions allows performing p-n-junctions and the junctions themselves in the form of thin films. Structure of the thermoelectric device represents a cascade (multilayer) thermomodule consisting of thermomodules, in which such materials of semiconductor branches of p-type 4 and n-type 5 are chosen that the flowing current on one of the junctions 2 will form emission, and not heating as in a common thermomodule; with that, in other junction 3 there will be absorption of heat energy in compliance with Peltier effect. Cascades are separated with electrically-insulating layers 1 with high transparency and heat conductivity. Direct current is fed from source 6.

EFFECT: obtaining ultra-low temperatures during cooling and heat removal processes.
