Definitions
- the invention has the object of providing a straight and / or curved tubes smooth surface existing heater, taking into account the characteristics of the external heat and the characteristics of the working gas in the heater tubes of the operating Stirling engine to change such that the efficiency of transmission is increased by external heat in the working gas of the Stirling engine.
- the advantages achieved by the invention are in particular that the heat transfer coefficient for the heat transfer from the inner tube wall into the working gas of the Stiriingmotors through the wells is up to four times as large as its value for a tube with a smooth inner surface, and that the heat transfer coefficient for the heat transfer from the outer heat flow in the outer tube wall through the wells is increased up to 100%.
