摘要： In a method of making finned tubes as components of air-cooled systems or condensers, a sheet metal strip of aluminum is first shaped into a waved finned structure with plural fins in parallel relationship and arched ends for connecting the fins, thereby defining crests on opposite ends of the finned structure. A fluxing agent of cesium-aluminum tetrafluoride is applied in lines onto the crests on at least one of the ends of the finned structure. The finned structure is then placed upon a broad side of a flat steel tube coated with a zinc/aluminum alloy. The finned structure and the flat tube are subsequently joined in a brazing furnace in the presence of an inert gas at a temperature between 370null C. and 470null C. to produce a unitary structure which is then allowed to cool down at room temperature.

摘要： In a method for joining a steel tube with an aluminum rib, a zinc-aluminum alloy layer, having an aluminum content of 0.5% by wt. to 20% by wt., is applied to the surface of the steel tube or the aluminum rib, and then a fluxing agent in the form of cesium-aluminum tetrafluoride is applied between the steel tube and the aluminum rib at room temperature before or during the mechanical contact of the aluminum rib with the steel tube. The steel tube provided with the aluminum rib is then heated to a soldering temperature of between 370null C. and 470null C. and subjected to room temperature to cool down.
摘要翻译：在将钢管与铝肋接合的方法中，铝 - 铝合金层的铝含量为0.5重量％至20重量％施加到钢管或铝肋的表面上，然后在室温或之前的室温下将四氟化铯 - 铝的形式的助熔剂施加在钢管和铝肋之间铝肋与钢管的机械接触。然后将具有铝肋的钢管加热至370℃至470℃的焊接温度，并经受室温冷却。
