ABSTRACT:
The invention provides a flat tube for a heat-exchanger conduit capable of being properly brazed and provides a sufficient heat-resistance, and a method of manufacturing it. A tube-stacking type heat exchanger comprising a plate made of an aluminum material including an aluminum alloy and which is cladded with a brazing material, wherein either a single plate is folded into two or two plates are placed one upon the other, the surface of one or both plates including projecting portion projecting from the surface of one plate to the surface of the other plate, the projecting portion is brought into pressure contact with the flat surface of the other plate or the projecting portion of the other plate, and the height of the end edge connecting portions of the plate is dimensioned smaller than the height of the projecting portion, to achieve the joining of the end edge connecting portions of the plate together.
