    摘要： Disclosed herein is an aluminum alloy clad sheet for a heat exchanger including a core layer, a sacrificial layer formed on one surface of the core layer, and a filler layer including an Al—Si based alloy formed on the other surface of the core layer. The core layer includes a predetermined amount of Si, Cu, Mn, Ti, and Mg, the remainder including Al and inevitable impurities, and the sacrificial layer includes a predetermined amount of Si, Mn, and Zn, the remainder including Al and inevitable impurities. The core layer has a crystal grain size after the brazing heat treatment at 595° C. for 3 minutes of at least 50 μm and less than 300 μm. The filler layer and the sacrificial layer are defined for their thickness, and the number of intermetallic compounds in the core layer is also defined to a predetermined range. By such constitution, the aluminum alloy clad sheet has improved fatigue life and post-braze strength, high corrosion resistance, and excellent erosion resistance and brazeability.
