Abstract This paper presents the integration and testing of a 165 K microcooler that operates with a sorption compressor and a micromachined cold stage. Attractive features of this combination are the lack of vibration and a long lifetime for a potentially very small cryocooler. The developed cold stage works with the vapor compression cycle and consists of a silicon condenser and flow restriction/ evaporator, which are combined with two miniature glass-tube counterflow heat exchangers. The thermal compressor consists of five miniature cells filled with adsorption material that are sequenced between ad- and desorption — thus providing a continuous pressure difference. The system was tested with ethylene gas operating between 14 and 1.5 bar, and produced a cooling power of 200 mW around 170 K with an input power of about 20 W.
