Abstract

1,216,189. Refrigerating; tubular heat exchangers. HYMATIC ENG. CO. Ltd. 9 April, 1968 [14 April, 1967; 24 Oct., 1967], Nos. 17356/67 and 48234/67. Headings F4H and F4S. In a Joule Thomson cooling apparatus, refrigerant gas is passed to the expansion nozzle through a frusto-conical coil of finned tubing and passes from the nozzle over the outer surface of the tubing. Gas in the tubing flows from the larger to the smaller end of the coil and gas outside the tubing flows in the reverse direction. As illustrated, the coil is located between a hollow frusto-conical member 16 and a block 10 which includes a chamber 12 for collecting any liquefied refrigerant. The lower part of the block contains or contacts the load to be cooled. The coil leads to an unfinned length of tube 26 which has a small hole in its wall forming the expansion nozzle. The wider end of the coil is connected to the gas supply by an unfinned length of tubing which passes through a mass 35 of solder in contact with the main body of the apparatus to aid the dispersion of heat of compression generated at start-up of the apparatus, Filaments 30 and 31 are wound between the coil and its locating members to promote heatexchange between the external gas flow and the coil.
