摘要： Corrugated fins that have high heat transfer performance and do not cause clogging even in a gaseous environment in which particulate matter such as dust is present have wall surfaces on which are formed alternating parallel ridges and furrows with an angle of inclination of 10-60°. Defining Wh as the height of the ridges and furrows, Wp as the period of the ridges and furrows, Pf as the period of the corrugated fins, and Tf as the thickness of the plate forming the fins, the following conditions hold. Wh≦0.3674·Wp+1.893·Tf−0.1584, 0.088
