FINNED TUBE HEAT EXCHANGER

摘要

A finned tube exchanger is provided with a plurality of fins and heat transfer tubes. The fins are provided with a first inclined section that is inclined with respect to the air flow direction so as to form at least one peak section, a tube periphery section that surrounds a heat transfer tube that passes through the first inclined section, and a second inclined section that is inclined with respect to the air flow direction so as to connect the tube periphery section and the first inclined section. A through hole is formed in the second inclined section, or a concave section is formed in the border between the first inclined section and the second inclined section. As a result, the heat exchange performance of the finned tube heat exchanger is improved.
