<p>A heater head (20) for use with a thermal regenerative machine (10) has a heater shell (122) formed from a single piece of material. The shell (122) has a tubular body with a cap-shaped end portion provided at a distal end and an open mouth portion provided at a proximal end. The heater head (20) also has a mounting flange (124) with a receiving portion configured to mate in fixed assembly with the open mouth portion of the heater shell (122). The mounting flange (124) is constructed and arranged to mount the shell assembly (122) to a housing (30) of the thermal regenerative machine (10). The shell (122) assembly and housing (30) are hermetically sealed therebetween. A heat exchanger (110) formed from a corrugated piece of sheet metal is affixed to an inner portion (123) of the heater shell (122) to form a plurality of working gas flow paths.</p> |
