Abstract

Abstract Translated from Japanese (57)【要約】 (修正有) 【目的】コルゲ−トフィンの座屈やルーバ部の変形を防 止する。 【構成】複数の伝熱チューブ20と複数のコルゲートフ ィン10を交互に積層した熱交換器において、上記コル ゲートフィン10は、波形の山12および谷部14の少 なくとも一方に切り込み18を形成した。 【効果】波形の山および谷部の少なくとも一方に切り込 みを形成したので、山または谷部の剛性が低下し、変形 量が大きくなる。このため圧縮された場合の寸法ばらつ きを吸収しやすくなり、ルーバ部の変形を防止し、かつ フィンの座屈を防止する。 (57) [Summary] (Modified) [Purpose] To prevent buckling of the corrugated fin and deformation of the louver. In a heat exchanger in which a plurality of heat transfer tubes 20 and a plurality of corrugated fins 10 are alternately laminated, the corrugated fins 10 have a cut 18 formed in at least one of a ridge 12 and a valley 14. [Effect] Since the notch is formed in at least one of the crest and the trough of the corrugation, the rigidity of the crest or the trough decreases, and the amount of deformation increases. For this reason, it becomes easy to absorb the dimensional variation when compressed, the deformation of the louver portion is prevented, and the fin buckling is prevented.
