    • A high performance louvered fin for a heat exchanger includes a base wall extending longitudinally to form a strip having a longitudinal axis. The high performance louvered fin includes a plurality of entrance louvers in the base wall extending outwardly at a predetermined angle in a first direction from the base wall. The high performance louvered fin also includes a plurality of exit louvers in the base wall extending outwardly at a predetermined angle in a second direction from the base wall reversed from the first direction. The entrance louvers and the exit louvers extend in a direction parallel to the longitudinal axis and are spaced laterally. The high performance louvered fin further includes a turnaround rib in the base wall extending laterally and generally perpendicular to the longitudinal axis between the entrance louvers and the exit louvers.
    • 用于热交换器的高性能百叶窗包括纵向延伸以形成具有纵向轴线的条的基壁。 高性能百叶窗包括在基壁中的多个入口百叶窗,其从底壁沿着第一方向以预定角度向外延伸。 高性能百叶窗还包括在底壁中的多个出口百叶窗,其从与第一方向相反的底壁沿着第二方向以预定角度向外延伸。 入口百叶窗和出口百叶窗沿着与纵向轴线平行的方向延伸并且横向隔开。 高性能百叶窗还包括底壁上的转向肋,其横向延伸并且大致垂直于入口百叶窗和出口百叶窗之间的纵向轴线。

    • The invention relates to a heat exchanger (1), especially for motor vehicles, which comprises flat pipes (2) through whose interior a first fluid (FL1) flows and that can be impinged upon externally by a second fluid (FL2). The flat pipes (2) are substantially disposed at an angle to the direction of flow (S2) of the second fluid (FL2) and parallel relative one another and are spaced apart so as to configure flow paths for the second fluid (FL2) that extend through the heat exchanger. Cooling ribs (3) are disposed in the flow paths and extend between respective adjacent flat pipes (2). A plurality of wavy ribs (3) are provided as the cooling ribs. These wavy ribs are disposed one behind the other in the direction of flow (S2) of the second fluid (FL2) and are off-set from one another in the direction of flow (S1) of the first fluid (FL1).

    • According to the present invention, in a corrugated fin type heat exchanger including a core portion having a plurality of flat tubes disposed in parallel relation with regard to a flow direction of air and at least one corrugated fin disposed between each pair of the flat tubes, a height of a flow space within the flat tube is in a range of 0.6-1.2 mm, a height of the corrugated fin is in a range of 3-6 mm, and a ratio (St/W.times.D) of the cross-sectional area (W.times.D) expressed by an overall width dimension (W) and a thickness dimension (D) of the core portion to a total cross-sectional flow passage area (St) of the plurality of flat tubes is set to a range of 0.07-0.24 according to the height of the flow space of the flat tube and the height of the corrugated fin. In this way, it is possible to reduce the Reynold's number of the flow passages within the flat tubes to maintain a constant region irrespective of the variation in the hot water flow quantity, thereby reducing the variation in the water side heat transfer rate.
