PURPOSE:To shorten the recovery time of working liquid and consequently improve the heat transporting performance by a structure wherein a subtank, the upper part of which is communicated through a valve to the upper part of a liquid receiving tank and the lower part of which is connected by a flow pipe to a heat exchanger, is provided below the outlet of a generator. CONSTITUTION:The high temperature vapor, which is developed at the solar heat collector 1 of a heat transporting device, of working liquid 12 is sent under the mixture of two phases of gas and liquid to a subtank 14 so as to be separated into steam and liquid and stored respectively in the upper space and the lower space of the subtank 14. The pressure in the subtank 14 is higher than the pressure in the solar heat collector 1, because the temperature in the solar heat collector 1 is lowered by the working liquid 12 recovered from a liquid receiving tank 7, while the high temperature in the subtank 14 remains as it is and consequently no pressure drop occurs in the subtank 14. Said higher pressure in the subtank 14 is led through a communicating pipe 11 to the liquid receiving tank, resulting in proceeding the recovery of the working liquid 12 without delay. |
