| 摘要 | PURPOSE:To make the time longer than hitherto in which a plate fin is blocked by frost, by making the thickness of frost which attaches to the plate fin uniformed by arranging cut-out parts on the plate fin part which situate at the up-stream side of a heat transfer pipe with regard to air flow. CONSTITUTION:Many people plate fins 1 and many heat transfer pipes 2 which intersect at right angles to said plate fins are provided. The cut-out 9 are arranged which situate at the up-stream side of the heat transfer pipes with regard to air flow. With this consequence, frost attaches in the uniform thickness on the plate fins, and the times in which spaces between fins are closed by frost become longer, and the operation time of a heat pump becomes longer and the numbers of times of frost melting is reduced, and the energy efficiency is remarkably improved. | ||||||
