Abstract

699,906. Refrigerators; tubular heat-exchange elements. FRESH FROZEN FOODS, Ltd., and SCHOFIELD, F. H. Sept. 20, 1950 [Oct. 27, 1949 No. 27604/49. Classes 29 and 64 (iii) A heat-exchanger tube 4 is provided internally with spaced longitudinal fins 5 and externally with parallel longitudinal fins 6, 7 the fins 6, 7 all being disposed on the same side of and at right angles to an axial plane of the tube. In the form shown the outer external fins 6 are tangential to the tube wall and the tips of the fins 6, 7 line in a plane parallel to the tube axis. The internal and external fins 5, 7 are aligned. Alternatively the fins 5, 7 may be relatively staggered or the fins 5 may extend radially from the tube wall. The cross-sectional shape of the tubes may be square, rectangular, circular, triangular or elliptical and a number of tubes may be cast as a single unit. Apparatus incorporating the above tubes is shown in Fig. 2. Shelves are formed in a cabinet 11 by arranging tubes in closely spaced or abutting parallel relationship with the fins, 6, 7 of each tube depending downwardly. Metal trays 10 containing goods to be frozen are placed on the shelves and a liquid or gaseous cooling medium is passed through the tubes. The air within the cabinet is circulated by a fan 12 and the goods in the trays are cooled, partly by conduction through the tube walls but mainly the air which is cooled by contact with the tubes. Specification 627,465 is referred to.
