Abstract

PURPOSE: For eliminating the trouble of additionally supplying liquid nitrogen, simplifying constructon and efficiently obtaining freezing output, to use an extremely low temperature freezer which uses helium gas and whose cold head and chevrons are combined into a single structure.
CONSTITUTION: The working liquid in a working liquid tank 2 is evaporated by a heater. Thus-obtained oil vapour is jetted out through a chimney 8 and a nozzle 9 to join the gas on high vacuum chamber 10 and 35 side. Thus-obtained mixture returns to said working tank 2 along the inner face of a case 8 while condensed. At this time, the chevrons 26 provided at the upper stage of the extremely low temperature freezer 21 using helium gas condenses the oil vapour returning from the gas discharge side space in said case 3 through the large through hole 42 of a partition plate 40. Further, the CO2 having condensed on the underside of the chevrons 27 provided at the lower stage of said extremely low temperature freezer 21 falls down while contained in the condensed oil vapour on gas discharge side. Thereby, clean high vacuum can constantly be obtained without any obstruction of CO2.
