Heat engine using thermal expansion of heat transfer fluid - is heated by solar panel with heat exchanger rotatably mounted on vertical axis and closed pump circuit

摘要

The heat engine has a heat source (1) which includes a closed circuit system with a heating fluid. The engine also has a heat exchanger system (3). The cold liquid (8) is connected to the heat exchanger system by the feeder arrangement (9). The solar panel (13) provides the power for the heating circuit (1). The system is controlled by the two way valves (13) on the hot side and (13a) on the cold side which may bypass the exchanger. The fluid is circulated by the pumps (17,17a).
