FINNED HEAT EXCHANGER

摘要

PROBLEM TO BE SOLVED: To provide a finned heat exchanger in which heat exchanging capacity is enhanced significantly while realizing compaction and cost reduction. SOLUTION: Any one or both of the front and rear edge parts of a raised part is formed in zigzag in the main flow direction of gas and the rising part of the raised part on the heat exchanger tube side is formed wider in the row direction as compared with other direction.
