FIN-AND-TUBE HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To provide a fin-and-tube heat exchanger which secure sufficient connection between a fin and a heat transfer tube by fixing the fin and heat transfer tube by brazing, and hardly causes a variation in a distance between adjacent fins.

SOLUTION: The fin-and-tube heat exchanger is constituted in such a way that collars 18 erected along the periphery of an attachment slit 16 on upper surfaces of fins 12 are inclined outward and front ends of inclined portions are brought into contact with lower surfaces of adjacent fins 12.
