Abstract
A cryocooler system having at least one flow straightener which has a system of grooves on its perforated surface for enhancing gas flow uniformity through the system wherein pulsing gas which does not initially pass through the flow straightener through a perforation flows along the surface of the flow straightener within a groove prior to passing through a perforation and is effectively redistributed across the surface of the flow straightener and thus the cross section of the regenerator or thermal buffer tube.
