Description
A helium phase separator with a condenser is under fabrication and assembly at National Synchrotron Radiation Research Center (NSRRC). The objective of a helium phase separator with its condenser is to separate two-phase helium flow and to re-condense vaporized gaseous helium with a cryo-cooler of Gifford-McMahon type. We developed a 100L helium phase separator with a small heat loss as a prototype, include resist radiation layers. The experimental results for the temperature difference and total heat load of the phase separator are consistent with simulation results; the deviation is within 20 %, which includes the effect of thermal conduction and thermal radiation. The total heat loss of the helium phase separator from experiment is 1.1 W and from simulation is 0.841 W. The mechanism of heat transfer in phase separator was investigated and is discussed. This paper presents the experiment and design of the condenser in the capacity of 100L separator.
