Summary

The Hampson-type miniature Joule-Thomson (J-T) cryocooler is widely used in electronic cooling. The authors develop the geometry model of the Hampson-type cryocooler to better understand the double helical tube-and-fin heat exchanger. The steady-state governing equations of the cryogen, helical tube and fins, and shield are solved numerically and yield good agreements with experimental data. The conventional way of simulating a Hampson-type J-T cryocooler, which is accompanied by a host of empirical correction factors, especially vis-à-vis the heat exchanger geometry could now be superseded. The effort and time spent in designing a Hampson-type J-T cryocooler could be greatly reduced. [Reprinted with permission from Elsevier. Copyright, 2005].
