PURPOSE:To carry out a suitable discharge to cause the carrier to return to a normal heat carrying state even when a non-compressive gas is accumulated by providing an electromagnetic valve at the upper part of a tank whose heat radiating side is hermetically closed tank, detecting the temperature or the pressure on a block whose heating side is hermetically closed so as to control the opening and closing of the electromagnetic valve. CONSTITUTION:When a working liquid 20 within a heat exchanger 7 is heated by the operation of a heat source 6 and begins to evaporate, the working liquid 20 is formed into air bubbles, which are subjected to gas-liquid separation by a gas-liquid separator 8. Steam then reaches a heat radiating part 13. The working liquid 20 the condensation heat of which the been robbed by the heat radiating part and which has been liquefied reaches a heat radiating side tank 18. When a non-compressive gas is accumulated within an enclosed system, the temperature and the pressure at the time of the heating operation rises up as compared with the normal time. Therefore, the temperature and the pressure are detected by detecting means 21, and an electromagnetic valve 19 is opened by the operation of a controller 22. Then, when the non-condensed gas collected at the upper part of the tank 18 whose heat radiating side is hermetically closed is discharged and the electromagnetic valve 19 is opened, the device is returned to the normal state. |
