Abstract: A process for soldering aluminum fins to cooling pipes made of aluminum, copper, brass or steel to produce a cooling assembly. The fins are etched in the solution of sodium hydroxide, zinc chloride, technical urea and water and the cooling pipes are coated with a fusible alloy which is covered with a protective coating for attenuating electro-corrosion between the alloy and the aluminum fins. The aluminum fins are then mounted on the cooling pipes and soldered thereto in a thermal bath.
