In a known device for converting of thermal energy into electrical energy which consists of a working circuit (2) with a working fluid for driving a turbo-engine (1) and of a plurality of heat exchanges (10) alternatively cross-flown by a cold and hot medium and in each of which an expansion element (9) is arranged that expands and contracts depending on the temperature of the medium, the temperature-dependent expansions and contractions of the expansion element (9) are immediately transmitted by a buffer storage to the working circuit. To avoid high requirements to the thermal insulation of suction and pressure conduits, it is proposed for storing a force, to associated a buffer storage formed as a spring (4) with each heat exchanger, where each spring (4) is connected with a piston (12) of a pressure cylinder (11) the working chamber (13) of which is connected by controllable valves and by the suction and pressure conduits (25, 15) with the working circuit.
