The aim was to provide a wide range of thermal and flow regimes necessary for experiments on HeII hydrodynamics and heat transfer as well as to test the realistic cryogenic equipment. The cryoblock is added to the 300 W / 4.5 K helium refrigerator to fulfil this task. This cryoblock contains series
Design methods for a subcooled superfluid helium refrigerator with high efficiency are studied. The design details are presented for a He I heat exchanger (perforated disk stack type), a He II heat exchanger (low fin tube type), an expansion valve, a safety valve, an initial filling valve and a pump
