Abstract

PURPOSE:To prevent the occurrence of construction, cracking, etc., in the rising part of slit fin by forming a slit fin group by continuously providing three the first to the third slip fins in the passing direction of air. CONSTITUTION:The second slit fin 6 is provided at a given level on the opposite side of the first slit fin 5 in relation to the remaining fin bae 3a. Therefore, the third slit fin 7 in the downstream is positioned at a correspondingly low level while exhibiting a maximum slit fin effect without being affected by the other slit fins, similarly to the first slit fin positioned at half the level of the pitch t of the fin base, making it advantageous correspondingly with respect to strength.
