R. Krishan et al., A SIMPLE HEAT-PIPE DEVICE FOR FREEZING ICE MANTLE IN TRIPLE-POINT OF WATER CELL, Indian Journal of Pure & Applied Physics, 32(1), 1994, pp. 87-88
An efficient isothermal device (based on heat-pipe principle) as a sim
ple immersion cooler, to freeze ice-mantle around the re-entrant well
of the triple-point of water cell, has been constructed for the requir
ement of maintenance of temperature standards.
