Abstract

PURPOSE:To enable to collect heat both at high temperatures and at low temperatures, by providing a heat-collecting member heated by the sunlight focused through a linear lens and a heat-collecting member heated by diffused light, and enable to take out electric energy, by connecting a thermoelectric converting element between the two heat-collecting members. CONSTITUTION:The sunlight available in the morning is focused on the first heat-collecting member 2 through the linear lens 1 to heat the member 2 to a high temperature of about 200 deg.C. Therefore, the first heat pipe 3 also starts to operate at about 200 deg.C, thereby heating a heat- transmitting medium flowing in the first heat-transmitting medium pipe 6. A controlling circuit 13 is operated by a signal from a temperature detector 12, whereby pumps P1, P2 intermediately provided in circulating passages 9a, 9b are operated, and solenoid change-over valves 10, 11 are so changed over as to communicate the passage 9a to a high-temperature heat-accumulating tank 8H. On the other hand, the second heat-collecting member 4 receives only the diffused light, so that it is heated only to about 40 deg.C, and a heat-transmitting medium of a low temperature is accumulated in a low-temperature heat-accumulating tank 8L. When the sun moves to its afternoon position, the system is changed over to a condition reverse to that during the morning by the temperature detector 12. In addition, a thermoelectromotive force corresponding to the temperature difference of 160 deg.C between the heat pipes 3, 5 is taken out by the thermoelectric converting element 15 through leads.
