Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 着霜による目詰まりまでの時間を長くする。 【構成】 コルゲートフィン3にルーバ10が切り起こ し形成されたルーバ部11とルーバ10を形成しない平 坦部12とを設ける。空気流路13を挟んでルーバ部1 1と平坦部12とが対向するよう配する。空気流がコル ゲートフィン3の表面およびルーバ10に当接すること により冷却されて熱交換が行われる。空気流の水分によ りルーバ部11から着霜が始まって平坦部12では着霜 しない。コルゲートフィン3の各段では着霜する部分と 着霜しない部分とが対向する。コルゲートフィン3の空 気流路13が大きく確保され、着霜による目詰まり状態 に至るまでの時間が長くなる。 (57) [Summary] [Purpose] To increase the time until clogging due to frost formation. A corrugated fin 3 is provided with a louver portion 11 formed by cutting and raising a louver 10 and a flat portion 12 not forming the louver 10. Louver part 1 with the air flow path 13 in between 1 and the flat portion 12 are arranged so as to face each other. When the airflow comes into contact with the surface of the corrugated fins 3 and the louver 10, the airflow is cooled and heat exchange is performed. Frost starts from the louver portion 11 due to the moisture in the air flow, and does not frost at the flat portion 12. In each stage of the corrugated fins 3, a frosted portion and a non-frosted portion face each other. The air flow path 13 of the corrugated fin 3 is secured large, and the time required to reach a clogging state due to frost formation becomes long.
