DISPLACER PISTON STRUCTURE FOR STERLING ENGINE

摘要

The present invention relates to a displacer mounted on a heating cylinder (10) for a StIrling engine. The displacer comprises: a piston (30) which is accommodated in the heating cylinder (10) to reciprocate, and has ventilation pores (32) for allowing high-temperature air and low-temperature air to pass; and A support frame (40) which is installed to surround the piston (30), and applies reciprocation force. Accordingly, it is possible to improve the overall efficiency of a system operation on the basis of a production technique to improve the heat exchange performance for the piston constituting the displacer of the Stirling engine.
