journal contribution
posted on 2023-05-17, 14:45 authored by Xiaolin WangXiaolin Wang, Chua, HT, Teo, HYThe Hampson-type miniature Joule–Thomson (J–T) cryocooler is widely used in electronic cooling. We 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 experiment 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is accompanied by a host of empirical correction factors, especially vis-à-vis the heat exchanger geometry could now be superseded.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 crycooler could be greatly reduced.
