Abstract
A heat exchanger stack apparatus for use on a remotely heated Stirling engine having a variable swashplate drive mechanism, which comprises rigidly combining a regenerator, a flexible heat exchanger, a short, rigid hot connecting duct and a cylinder. A heat exchanger stack apparatus for each cylinder of the engine is mounted on a drive mechanism housing with the regenerator adjacent to a cooler located within the drive mechanism housing. The cooler, regenerator and flexible heat exchanger are axially aligned providing a linear flowpath for the engine working fluid. Bellows and flexible tubes connected to the flexible heat exchanger provide axial and transverse flexibility to reduce thermal stresses within the heat exchanger stack apparatus.
