Abstract

PURPOSE: To improve the heat transfer rate between both a heat transfer plate and a noncircular heat transfer tube by integrally forming the heat transfer plate and the heat transfer tube by a strong facial pressure.
CONSTITUTION: The present heat transfer unit is constituted by a heat transfer plate 1 and a noncircular heat transfer tube 2. The heat transfer plate 1 comprises a flat part 11, a noncircular tubular projection 12 projecting to one side of the plate face and integrally formed with the flat part 11, and a groove 13 communicated with the interior of the tubular projection 12 and opened towards the other side of the plate face. Said groove 13 is positioned between a pair of bent edges 14, and said edges are communicated with the flat part 11 and the tubular projection 12, respectively. Within the tubular projection 12 there is accommodated a noncircular heat transfer tube 2 having a cross sectional shape equal to that of said tubular projection 12. The heat transfer tube 2 tightly adheres to the inner peripheral wall surface of the tubular projection 12 with rigidity and clamped thereby. As a result, the heat transfer rate between the heat transfer plate 1 and the heat transfer tube 2 becomes extremely excellent.
