PULSE TUBE REFRIGERATION SYSTEM

摘要

A pulse tube refrigeration system, having a pulse generator (1), a regenerator (52) and a pulse tube (10), comprising a work transfer tube (3) interposed between the pulse generator and the regenerator wherein the work transfer tube has a cross section at the end proximate the pulse generator which differs from the cross sectional area proximate the regenerator, enabling a reduction in heat transfer due to streaming within the work transfer tube.
