二重境膜剥ぎ取り熱交換装置

Double laminar film stripping heat exchanger device

Abstract

PROBLEM TO BE SOLVED: To enlarge a heat transfer area without causing stagnation of fluid flow and to strip laminar films in a wide range to remarkably improve a heat transfer accelerating effect in a double laminar film stripping heat exchanger device stripping laminar films at the inner and outer peripheral surfaces of a rotationally driven inner tube. SOLUTION: In this double laminar film stripping heat exchanger device 1, a plurality of circular fins 12 having fluid passages 13 at the outer peripheral part of the inner tube 10 are erected at predetermined spaces in the length direction of the inner tube 10 to partition an outer passage 31, and an outer fixed blade 50 is formed in comb shape close to the outer peripheral surface of the inner tube 10 and the front and rear faces of the fins 12 to strip laminar films on the outer peripheral surface of the inner tube 10 and the front and rear faces of the fins 12.
