In the heat medium circulation path, which forms a closed loop in which the heat medium circulates, the heat medium receives heat in the heat absorption part and becomes a gas phase, and radiates the heat in the heat radiation part to form a liquid. The above-mentioned heat absorption part and heat radiation part form a closed loop using a phase fluid, and the heat radiation part is located at a higher position relative to the heat absorption part at the rising and falling parts on opposite sides of the heat medium circulation path. A control valve whose opening degree can be adjusted is installed in the heat medium flow path from the heat radiating part to the heat absorbing part, so that the liquid level in the falling part where the heat radiating part is provided is equal to the liquid level in the rising part where the heat absorbing part is provided. The heating medium is controlled to be maintained higher than the liquid level, and the heating medium is circulated through a closed loop circulation path due to the difference in the liquid level of the heating medium.
