Abstract
1,136,018. Heat exchanger tubes; revaporizers. GENERAL DYNAMICS CORP. 10 May, 1966 [13 May, 1965], No. 20575/66. Headings F4P and F4S. A cryogenic vaporizer comprises a circular row of vertically extending, externally finned heat exchange tubes interconnected in series or in parallel to form a flow path between an inlet 10 and outlet 12. A plurality of fins is associated with each tube and these extend vertically and are formed from a single sheet, this being bent into the shape of a regular triangle having a pipe such as 52 as apex with the two sides (58, 59) defining the apex being made to extend past the pipe to form diverging fins 60 and 61. The pipes are preferably made of brass and the fins of copper or any other metal having a thermal conductivity which increases with decreasing temperature. Flowing through the compound exchanger, the outer wall of which is defined by arranging side-by-side the bases of all the triangular fin members, is a stream of air at ambient temperature, this being provided by a fan (80) disposed above said exchanger. A liquefied gas supplied to inlet 10 is said to be efficiently vaporized before reaching the outlet 12, this efficient heat transfer being attributed to both the arrangement of the fins and their conductivity. Both factors are said to reduce ice formation on the fins.
