| 摘要 | PURPOSE:To improve the heat transfer performance and the defrosting efficiency of the heat exchanger by disposing air inlet side fin group and a concave and convex fin group on the air outlet side overlapping in an air stream direction. CONSTITUTION:Flat shaped fins 12 and wave-shaped fins 13 are alternately disposed on the air outlet side, and flat shaped fins 11 are disposed on the air inlet side and wave-shaped fins 13 are disposed at positions where are overlapped in the air stream direction. Particularly, the air stream repeates refraction, expansion and contraction, and the air heat coefficient in the wave-shaped fins 13 increases. As a result, the heat exchange quantity increases and a frost layer is formed in the wave-shaped fins 13. Hence, at the time of defrosting heat is not discharged excessively but the defrosting efficiency is also improved. Further, in the undulation shape fins, such as wave-shaped fins, the heat transfer property is not rapidly lowered by the formation of the frost layer. | ||||||
