ABSTRACT:
A cooling load90is enclosed within the envelope of the pressure vessel that contains the working fluid in a pulse tube cooler in a load space95adjacent to a regenerator58of that pulse tube cooler. Flow-smoothing means63, which include stacked screens and perforated plates, or diffuser nozzle104or diffuser cone106, spreads the flow of fluid that enters the cold end of pulse tube66.
