Abstract

PURPOSE:To control the flow round a tube and recover the flow rate in a dead water zone downstream of the point of peel for forming a flow straightening plate at the section of a fin which corresponds to a neighborhood of the peel section of the boundary layer in a heat exchanging medium on the outer circumference of the tube. CONSTITUTION:In a fin 11 a hole of insertion is formed by punching it out and the flange-shaped inner brim 13 is provided with projecting pieces in series at its two positions. The projecting pieces 14 are bent back by nearly 180 deg. degrees to the side of the fin to form a flow straightening plate 15. A plurality of fins 11 are stacked with the end section 13a of one inner brim 13 abutting that of another inner brim 13 among the fins. And, through each insertion hole 12 a tube 1 is inserted through which a medium flows to be heat-exchanged and at the inner brim 13 the tube 1 and fin 11 make contact no make it possible to transfer heat between them. The air flow which is fast at the outside of the boundary layer is led to a dead water zone by the flow straightening plate 15 of the fin 11 so that the air flows without reducing its speed and the cooling efficiency is improved.
