Abstract
A Stirling engine capable of utilizing air as a working fluid which includes a compact heat exchange module which includes heating tube units, regenerator and cooler positioned about the combustion chamber. This arrangement has the purpose and effect of allowing the construction of an efficient, high-speed, high power-density engine without the use of difficult to seal light gases as working fluids.
Claims8
A Stirling engine which includes a compression means and expansion means;
- a combustion chamber for generating heat;
- a cylindrical shaped heat exchange module positioned about the combustion chamber to accept the transfer of heat therefrom, said heat exchange module includes a plurality of heater tube units positioned circumferentially about said combustion chamber and through which working gas passes and is heated, regenerator means in the form of a fiber matrix, cooling means for cooling the working fluid, said heating tube units, regenerator means and cooling means, each being cylindrical in shape and positioned respectively in a layered fashion each about the next;
- cold connecting duct means coupling the cooling means with the compression means so as to enable the passing of the working fluid therebetween;
- hot connecting duct means coupling the heating means with the expansion means so as to enable the passing of working gas therebetween;
- and said compression and expansion means operate to provide a periodic flow of working gas through the heat exchange module in a Stirling cycle of operation.
