摘要： PROBLEM TO BE SOLVED: To provide a metal heat exchanger made of a metal containing aluminum without containing hexavalet chromium, having a high hydrophilicity, corrosion resistance, deodorizing property over a long term. SOLUTION: A first protective layer formed of a chemical conversion coating without containing hexavalent chromium on the surface of an aluminum-containing metal base-material of a heat exchanger, and a second protective layer is formed on the first protective layer. The second layer is formed of a hydrophilic and hardly water-soluble resin film containing a reaction product of a resin component (a) containing a water-soluble polymer having at least one of hydrophilic group selected from the groups consisting of primary, secondary, or tertiary amino, quaternary ammonium, amide, carboxyl, sulfone, ethylene oxide, phosphonate, and hydroxyl, and a cross- linkable group selected from the groups of amide, carboxy, and hydroxyl, and a different kind from the above selected hydrophilic group, and a cross-linking agent component (b) containing (i) a trivalent chromium component and (ii) a fluorocomplex salt compound in the total amount exceeding an equivalent for cross-linking the resin components.

摘要： PROBLEM TO BE SOLVED: To provide a heat exchanger capable of reducing in weight and preventing its side plates from deformation. SOLUTION: The heat exchanger is structured so that a plurality of tubes 2 admitting flowing-through of a fluid and a plurality of corrugated fins 5 are laminated to form a heat exchange core 7. Tanks 3 and 4 are connected to the ends of the tubes 2, and side plates 6 are attached to the two sides of the core 7, whereto the joining parts between the tubes 2 and the corrugate fins 5 are brazed solidly. The end of the side edge 6a of each side plate 6 is folded to generate a double structure. COPYRIGHT: (C)2004,JPO
