Abstract
Brazed double wall plate heat exchangers are manufactured so that the double walls are connected and sealed to each other around port holes of the exchanger. This is obtained by providing areas that are shaped so as to include areas not covering each other. The brazing is provided by capillary suction of brazing material from other plate areas.
