Abstract: A heat exchanger is provided with a first tank and a second tank. Heat transfer tubes are disposed between the tanks and are connected to the tanks to place the tanks in fluid communication. Either of the tanks may be divided into chambers by a partition. The partition has at least one portion which is oriented to be angularly offset from the direction of an air flow passing through the heat exchanger. The orientation of the partition permits the heat transfer tubes to be connected to the tanks in an arrangement so that no portion of the air flow can pass through the heat exchanger without striking at least one of the heat transfer tubes.

Abstract: A serpentine-type aluminum heat exchanger comprising a serpentine-anfractuous flat tube of an aluminum alloy and a plurality of corrugated fin units made of an aluminum alloy having a high aluminum content of 99 wt. % or more, and joined to the flat tube by brazing metal coating layers fixed onto flat surfaces of parallel portions of the serpentine-anfractuous flat tube. The heat exchanger is produced by preparing the serpentine-anfractuous flat tube of an aluminum alloy, the corrugated fin units and foil plates of an aluminum alloy brazing filler metal, disposing the fin units in spaces between adjacent ones of parallel portions of the serpentine-anfractuous flat tube with foil plates being interposed between respective fin units and opposite parallel portions of the flat tube, and heating the flat tube, the fin units and foil plates in the assembled relation to the brazing temperature.

Abstract: Aluminum metal piece is dipped into a molten aluminum alloy brazing filler metal covered with a flux layer melted by heat of the molten filler metal, and thereafter is taken out therefrom. Thus, the aluminum metal piece is readily coated with a double coating film of the aluminum alloy brazing filler metal and the flux coating film.
