摘要： An aluminum heat exchanger is made from flat aluminum tubes formed with side edge projections having engaging surfaces and coated with brazing material on the outside surface but not on the inside surface of the tube or the projections. The opposite ends of the tubes are inserted into flat tube insertion holes in opposed header tanks which have a brazing material coated on the peripheral surface of the tank, so that, during brazing of the assembled heat exchanger components, brazing material flows from the header tanks to the engaging surfaces of the flat tubes.
