Document Type and Number:
Japanese Patent JP2004263881
Kind Code:
A
Abstract:
To provide a heat transfer fin for improving heat transfer efficiency, reducing a pressure loss, and having superior heat exchange performance.
A corrugate fin 53 is arranged between a plurality of respective heat exchange tubes 51 and 52. The corrugate fin 53 is formed by meanderingly continuously connecting louver fins 54 arranged in parallel at a prescribed interval in the tube longitudinal direction. A ventilation passage 56 is formed between the respective louver fins 54, and a plurality of louvers 55 are formed in a cut and raised manner at a proper interval in the louver fins 53. The windward side edges 54a and 55a of the louver fins 54 and the louvers 55 are formed in a semi-elliptic shape getting thinner toward the windward side.
