FIELD: engine building.
SUBSTANCE: method for increasing the efficiency of heat exchange processes in a Stirling engine consists of using a twisted shape of the tubes of the heater (11), cooler (18), preheater (16) and a cylindrical regenerator (17), including due to the finning of their inner surface in the condenser section; at the same time, to increase the efficiency of the regenerator, the coolant from the combustion chamber is supplied to the inlet of the regenerator (17), and the cooler to its outlet, using heat pipes. A variant of a method for increasing the efficiency of heat exchange processes in a Stirling engine is also disclosed.
EFFECT: increase of efficiency of the Stirling engine.
