    摘要： An evaporator has plural tubes arranged in parallel with each other in a width direction perpendicular to an air flowing direction. The tubes are further arranged in a plural rows in the air flowing direction, and tank portions extending in the width direction are arranged in the plural rows in the air flowing direction to correspond to the tubes. In the evaporator, refrigerant flows through a zigzag-routed refrigerant passage formed by the tank portions and the tubes. A partition wall defining adjacent two tank portions in the air flowing direction has plural bypass holes through which the adjacent two tank portions directly communicate with each other. Therefore, the zigzag-routed refrigerant passage of the evaporator is readily formed without an additional side passage or the like. Thus, the number of components of the evaporator is reduced thereby simplifying the structure of the evaporator, and pressure loss of refrigerant flowing in the evaporator is decreased.

    摘要： Disclosed herein are aluminum alloy fin materials useful for heat exchangers which consists of, in weight percentage, 0.8 to 1.8% Fe, 0.3 to 3.0% Zn, up to 0.3% Cu and at least one element selected from the group consisting of 0.05 to 0.25% Zr and 0.05 to 0.25% Cr, with the balance being Al and unavoidable impurities, wherein Mn in the unavoidable impurities is 0.3% or less. The fin material being characterized, after brazing, by its superior thermal conductivity and beneficial sacrificial anode effect. The fin material is also suitable as a core of a brazing fin material in combination with an Al-Si alloy brazing material in which the Al-Si alloy brazing material is clad as an outer cladding layer onto both sides of the core. The above unclad or clad fin materials can provide heat exchangers having high corrosion resistance and good heat transfer characteristics in combination with a fluid passage material made of brazing sheet or an extruded tube of pure aluminum or an aluminum alloy with not more than 0.5% Cu and/or not more than 0.5% Mn.
