HEAT-TO-ELECTRIC POWER CONVERTER

摘要

The converter comprises a linear alternator consisting of a stationary armature and a field winding which is capable of linear reciprocating motion within the armature. A fluid is circulated within a closed loop system so as to operate a driving machine constituted by an expansion section and a compression section each containing a piston directly connected to the field winding for carrying out the reciprocating motion and causing simultaneous expansion and compression of the fluid within the two sections. The hot fluid which is discharged from the expansion section and the cold fluid which is discharged from the compression section are circulated in two circuits in opposite directions within a heat exchanger and then fed back respectively into the compression section and the expansion section.
