THERMOELECTRIC CASCADE-TRAY COOLER Russian patent published in 1995 - IPC

FIELD: refrigerating engineering. SUBSTANCE: thermoelectric cascade-tray cooler has arms of thermoelements in all upper cascades built up of several parts 5,6 equal in height and interconnected in series in respect to electric and thermal flows, one part per cascade; quantity of parts equals cascade number; total height of each arm in all stages is the same. When electric current is supplied, thermoelements at cold junctions of bottom cascade emit cold which cools down plate 4 and, hence, base of top of arms 6 of second cascade thermoelements functions as lock limiting inflow of heat. EFFECT: reduced consumption of expensive thermoelectric material, reduced power requirement and lag of thermoelectric cascade tray cooler. 1 dwg
