Abstract:Two demonstrator versions of a small Linde-Hampson cooler with glass tube heat exchanger are presented. The fabrication of these coolers are described and experimental results are presented and discussed. One cooler with a length of 270 mm and an outer diameter of 0.67 mm has a cooling power of 60 mW at 88 K with a mass flow of 7.3×10−6 kg/s (0.35 ln/min1) nitrogen gas. The lowest temperature measured is 82 K at a mass flow of 4.2×10−6 kg/s. The other shorter cooler has a length of 105 mm and the same outer diameter. It could also reach 82 K with a flow of about 2×10−6 kg/s. In both cases nitrogen gas was supplied at a pressure of 10 MPa.
