<p>PROBLEM TO BE SOLVED: To suppress the space occupied by a cooling system and, at the same time, to satisfactorily maintain the efficiency of the system. SOLUTION: A cryogenic vessel is provided with a pulse pipe refrigerating machine A having a pressure source 1, cold storage tank 6, condenser 7, pulse pipe 9, radiator 10, and phasing device 12 and a reservoir 21 fixed to a vacuum tank 31 through heat insulating supporting means 36 and 37. In the vessel, the condenser 7 is provided in the gaseous phase section 21a of the reservoir 21 in a state where the condenser 7 is stuck to the low-temperature end 6b of the cold storage tank 6 and the pulse pipe 9 is arranged in the liquid phase section 21b of the reservoir 21 in a state where the high-temperature side end of the pipe 9 is stuck to the vacuum tank 31 and the low-temperature side end 9b of the pipe 9 is positioned on the downside. In addition, the low- temperature side 9b of the pipe 9 is set up in the vacuum tank 31 provided on the outside of the reservoir 21 and is made to communicate with the condenser 7 through a pipeline 8.</p> |
