Abstract

PURPOSE:In a heat exchanger provided on the outer surfaces of heat transmission tubes with a large number of fins, to form said fins into a shape to exhibit a turbulent flow or an entering edge operation with respective to flowing air thereby to prevent the development of the temperature border layer and improve the heat transmission ratio. CONSTITUTION:In a counter air heat exchanger consisting of heat transmission tubes 11 arranged in a large number of steps and columns and a large number of fine 2... provided on outer surfaces of said tubes in intersecting manner, said heat transmission tubes 1 are provided with two-system spiral grooves 8 forming inclination angles of mutually inverse directions with respect to the tube axis, and said fins 2... are formed by a lot of tube inserting holes 3... formed in corrugated fin base plates 21, and between adjacent holes 3 and 3 there are formed slits 5... slitted in parallel to the edge line of the corrugating and tongue pieces 6.... Now, when air is sent in the direction of intersecting each edge line 4, air flows in zigzag while flowing turbulently using the edge time as a turning point within a corrugated passage 7, and the formation of the temperature border layer is prevented.
