Abstract
A temperature adjusting device has an air-tight container. A thermoelectric element is disposed in the air-tight container and has first and second opposite surfaces each capable of radiating and absorbing heat through a Peltier effect. A first heat exchanger is disposed in the air-tight container for performing heat exchange between a thermally conductive first medium and the first surface of the thermoelectric element. A tank is disposed in the air-tight container and is connected to an inlet side of the first heat exchanger for storing the first medium. A second heat exchanger is disposed in the air-tight container for performing heat exchange between a thermally conductive second medium and the second surface of the thermoelectric element. A pump circulates the first medium through the first heat exchanger. A temperature sensor detects a temperature of the first medium circulated by the pump. A controller controls an electric current supplied to the thermoelectric element so that a temperature detected by the temperature sensor becomes equal to a preselected temperature value.
