    • A cross-fin tube type heat exchanger having a large number of parallel fins and a plurality of heat transfer tubes extended through and fixed to the fins, so that heat may be exchanged between a first heat exchanging medium flowing through the heat transfer tubes and a second heat exchanging medium flowing along the surfaces of the fin, across the walls of the heat transfer tubes and through the fins. In the portions of each fin between adjacent heat transfer tubes of the same row, formed are a number of slits perpendicular to the direction of flow of the second heat exchanging medium. Each elongated section defined between each pair of adjacent slits is bent along its breadthwise bisector line and is raised in the form of a bridge to constitute an upwardly convexed louver element. The upwardly convexed louver element may have a cross section with an obtuse apex angle, or may have an arcuate cross section. The successive louver elements are arrayed in the direction of flow of the second heat exchanging medium in a manner of corrugation, or alternately staggered in the heightwise direction so that the edges of adjacent louver elements may be staggered in the heightwise direction. The fins having louver elements thus constructed cause a turbulency of the flow of the second heat exchanging medium to effectively prevent boundary layers of the latter from growing, thereby to ensure a higher efficiency of the heat exchange. Also increased stiffness or rigidity of the fin is obtained thanks to the provision of upwardly convexed louver elements.
    • 一种具有大量平行翅片和多个传热管的交叉翅片管型热交换器,其延伸并固定在翅片上,使得热量可以在流过传热管的第一热交换介质和 第二热交换介质沿着翅片的表面流动,穿过传热管的壁并且通过翅片。 在相邻行的相邻传热管之间的每个翅片的部分形成有垂直于第二热交换介质的流动方向的多个狭缝。 限定在每对相邻狭缝之间的每个细长部分沿着其宽度方向的平分线弯曲并且以桥的形式被升高以构成向上凸起的百叶窗元件。 向上凸起的百叶窗元件可以具有钝角顶角的横截面,或者可以具有弓形横截面。 连续的百叶窗元件以波纹的方式在第二热交换介质的流动方向上排列,或者在高度方向上交错排列,使得相邻百叶窗元件的边缘可能在高度方向上交错。 具有如此构造的百叶窗元件的翅片导致第二热交换介质的流动的湍流,以有效地防止后者的边界层生长,从而确保更高的热交换效率。 由于提供了向上凸起的百叶窗元件,还获得了翅片的增加的刚度或刚度。
