<p>PURPOSE:To easily mount a heat receiving fin to a heater tube, by forming the heat receiving fin, provided in the periphery of the heater tube arranged spacing a distance in a combustion chamber, by a plate unit of bellows shape having penetration holes overlapped with each other in each folded part. CONSTITUTION:A combustor of a Stirling engine, formed by parallelly arranging plural heater tubes 1 spacing a distance in a combustion chamber partitioned in a housing, absorbs heat from combustion gas, generated by a burner provided in the central part of the combustion chamber, through heat receiving fins 2. Here the heat receiving fin 2 is formed by a plate unit made of heat resisting alloy plate and folded in a multi-layer bellows shape. While penetration holes 21, almost coaxially overlapping with each other, are formed in each folded part 20 of said heat receiving fin 2, and after the heater tube 1 is inserted into said penetration holes 21, the both heater tube 1 and heat receiving fin 2 are integrally formed by brazing.</p> |
