This is a heat exchanger having a heating cycle part and a thermal cycle part. The heating cycle part comprises a compressor which is driven by the thermal power cycle in a heating medium circulation line connecting a radiator and an evaporator while the thermal power cycle part includes a turbo-engine in the thermal power medium circulation line connecting a condenser and an evaporator. The output shaft of the turbo-engine is connected to the compressor, and a heater as a constant heat source is provided for heating the evaporator in the thermal power medium circulation line. If the compressor is replaced with a power generator, the heat exchanger can be used as a power generator/heat exchanger of temperature-difference-driven type. The components are housed in a pressure vessel to thereby simplify the structure without necessity for a special pressure resistance structure.
