Abstract: An aluminum alloy brazing sheet including a core material and a brazing material provided on at least one surface of the core material. The brazing material includes 5.0-9.0 mass % Si, 0.10-0.90 mass % Mg, and 0.05-0.60 mass % Bi, and further includes at least one of 0.80 mass % or less Mn and 0.60 mass % or less Ti, with the remainder being Al and inevitable impurities.

Abstract: In a heat exchanger for a vehicle, a cover member covers an upstream side end that is a part of an outer peripheral surface of a tube in which a heat medium flows, on the upstream side of the air flow. Further, the cover member is fixed to the upstream side end of the tube. For example, a width of the cover member is equal to or less than that of the tube in a direction perpendicular to the air flow direction and a flow direction of the heat medium. Thus, the heat exchanger can prevent the misalignment of the cover member with respect to the tube, thereby protecting the tube by the cover member at the front side of the vehicle. Therefore, the tube can be protected from chipping.
