INVESTIGATION OF CIRCUIT FOR COLD TRANSFER IN LOW CAPACITY CRYOGENIC SYSTEM.
Author(s) : LYAPIN V. I., PROUSMAN Y. O.
Summary
THE DESIGN AND RESULTS OF A TEST ON A NEW CIRCUIT FOR COLD TRANSFER FROM A SMALL SIZE STIRLING CRYOCOOLER WITH A REFRIGERATING CAPACITY OF ABOUT 100 WATTS AND WORKING AT A TEMPERATURE OF 80 K ARE DESCRIBED. FOR HELIUM CIRCULATION UNDER PRESSURE OF 5 MEGAPASCALS, A CENTRIFUGAL FAN WITH COLD GAS COMPRESSION WAS DESIGNED. AT A TEMPERATURE OF 80 K, THE MAXIMUM HEAD IS 14.5 KILOPASCALS, THE ELECTRIC POWER CONSUMPTION IS LESS THAN 16 WATTS, THE HEAT LOSSES IN THE CIRCUIT ARE LESS THAN 5 WATTS AND THE ROTATING SPEED IS 1,300 RAD/SEC. PROSPECTS FOR FURTHER IMPROVEMENT OF THE CIRCUIT WITH CENTRIFUGAL FAN ARE DISCUSSED.
