    摘要: A protect structure, of a heat exchanger for a motor vehicle, includes a core part of the heat exchanger and a protect member. The core part has a plurality of tubes and fins that are alternately arranged with each other, and the protect member is provided at a front side of the core part. The protect member has a plurality of protecting portions extending in a longitudinal direction of the tubes to cover front sides of the tubes of the core part and avoid a collision between the core part and an attack object that is flown from an oblique front side of the motor vehicle toward the core part.

    摘要: The present invention provides a high-strength aluminum alloy extruded product exhibiting excellent corrosion resistance and secondary workability and suitably used as a structural material for transportation equipment such as automobiles, railroad vehicles, and aircrafts, and a method of manufacturing the same. The aluminum alloy extruded product has a composition containing 0.6 to 1.2% of Si, 0.8 to 1.3% of Mg, and 1.3 to 2.1% of Cu while satisfying the following conditional expressions (1), (2), (3), and (4), 3%≦Si %+Mg %+Cu %≦4%   (1) Mg %≦1.7×Si %   (2) Mg %+Si %≦2.7%   (3) Cu %/2≦Mg %≦(Cu %/2)+0.6%   (4) and further containing 0.04 to 0.35% of Cr, and 0.05% or less of Mn as an impurity, with the balance being aluminum and unavoidable impurities. The cross section of the extruded product has a recrystallized structure with an average grain size of 500 μm or less. The manufacturing method includes, when extruding the aluminum alloy into a solid product by using a solid die, extruding the aluminum alloy by using a solid die in which a bearing length (L) is 0.5 mm or more and the bearing length (L) and the thickness (T) of the solid product have a relationship expressed as “L≦5 T”, and, when extruding the aluminum alloy into a hollow product by using a porthole die or a bridge die, extruding the aluminum alloy while setting the ratio of the flow speed of the aluminum alloy in a non-joining section to the flow speed of the aluminum alloy in a joining section in a chamber, where the billet reunites after entering a port section of the die in divided flows and subsequently encircling a mandrel, at 1.5 or less.
