Summary

THE THERMOSIPHON MADE OF STAINLESS STEEL HAS A THERMAL RESISTANCE WHICH IS A FUNCTION OF HEAT TRANSFER RATE AT VARIOUS FILLING RATIOS IN THE VAPOUR PRESSURE RANGE FROM 50,000 TO 200,000 PASCALS. THE EFFECTIVE THERMAL CONDUCTIVITY DETERMINED FROM THE EXPERIMENTAL RESULTS WAS FOUND TO BE ABOUT 24 TIMES AS LARGE AS THAT OF COPPER. THE MAXIMUM HEAT TRANSFER RATE, WHICH IS 94 WATTS, IS ALMOST SAME AS THAT OF THE HALOGENATED-REFRIGERANT THERMOSIPHON IN THE MODERATE TEMPERATURE RANGE.
