Abstract: To develop effective heat exchangers for miniature and micro-Joule-Thomson (J-T) cooling system, the performance of the recuperative heat exchanger in a miniature J-T cooler is analyzed and evaluated. The evaluation is based on a theoretical model of the Hampson-type counter-flow heat exchanger. The effect of the pressure and temperature-dependent properties and longitudinal heat conduction are considered. The results of the numerical simulation are validated with the corresponding experimental measurements. The performance of the heat exchanger on effectiveness, flow and various heat conduction losses as well as liquefied yield fraction are analyzed and discussed. The simulation model provides a useful tool for miniature J-T cooler design. © 2001 Elsevier Science Ltd. All rights reserved.
