METHOD FOR MEASURING OF PELTIER-EFFECT RATE ON ELECTRIC CIRCUIT WITH DISSIMILAR CONDUCTORS AND DEVICE WHICH IMPLEMENTS SAID METHOD Russian patent published in 1999 - IPC

FIELD: electrical engineering. SUBSTANCE: method involves running direct current through electric circuit consisting of two electrodes of dissimilar materials. Direction of direct current should cause absorption of Peltier-effect heat in junction to cool it. So, alternation of junction temperature and measuring thermoelectric power values help in detection of dependence of Peltier-effect rate on temperature of junction in electric circuit. Peltier-effect and Joule heat amounts are completely separated and are taken into account upon measurement of Peltier-effect rate. Corresponding device has direct current source, variable resistor, millimeter, three-terminal switches, gage of thermoelectric thermometer, glass bulb which contains electrodes from materials under investigation, heater, controlled source of alternating voltage, constant resistor, differential amplifier, controlled voltage divider and millivoltmeter. EFFECT: elimination of need for compensation of Joule heat influence on electric circuit junction. 2 cl, 1 dwg
