HEAT TRANSFER HEAD FOR A STIRLING ENGINE

摘要

A heat transfer head (10) for a stirling engine is disclosed. The heat transfer head (10) comprises a plurality of external circumferential fins (30) projecting out from the heat transfer head (10). At least two of the adjacent fins (30) are arranged to be substantially parallel and such that some of the radiant heat received by one of the fins is reflected onto the other fin. A second set of fins (40) is provided above the circumferential fins. The second set of fins are arranged to enable combustion gases from a burner to pass upwards therebetween to enable heat to be absorbed from the passing combustion gases.
