The regenerators in standard pulse-tube refrigerators are large, heavy, expensive, and are a source of losses. In this contribution we avoid using regenerators by combining two pulse-tube refrigerators which operate in opposite phase. The regenerators are replaced by a counterflow heat exchanger. We treat the basic thermodynamic equations, make some design considerations, and report the results of some preliminary experiments. ©2002 American Institute of Physics.
