Description
The aim of the Joule Thomson microcooling research at the University of Twente is to develop small and fully integrated cryogenic cooling systems for cooling small electronic devices. In the previous project, we have successfully developed 100 K single-stage microcoolers and 30 K two-stage microcoolers using standard micromachining technology. In the paper, we now present three new developments: microcoolers with double-expansion aiming at lower operating temperatures or higher efficiency; microcoolers with thermoelectric precooling aiming at lower operating pressures or higher efficiency; and microcoolers with different support pillar matrices in the counter flow heat exchangers aiming at higher efficiency.
