摘要:
The inlet and outlet temperatures and the block temperature of a discrete heat exchanger in a dilution refrigerator have been measured. Temperatures measured on the outgoing3He&sngbnd;4He stream were higher than temperatures predicted theoretically; this discrepancy has been attributed to viscous effects within the dilute3He&sngbnd;4He channel which degrade the performance of the heat exchanger significantly below 80 mK.
