PURPOSE: A device of controlling temperature of a refrigeratory using a thermocouple is provided to prolong the lifecycle of the thermocouple by eliminating the need to turn on/off the thermocouple periodically as the temperature changes. CONSTITUTION: The device of controlling temperature of a refrigeratory using thermocouple includes a power supply(10), a transformer(12), a controller(14), a DC power source(20), a thermocouple(26), a refrigeratory tank(24), a cooling pan(18), a temperature detecter(16), and a display(22). The controller(14) produces a preset power source or control signal by conducting calculation or logic control with the source and signal. The DC power source(20) produces a preset level of voltage by decreasing the input power source coming from the controller. The temperature of the thermocouple(26) rises or falls at the junction responding to the source from the DC power source(20).
