ABSTRACT:
A method of brazing a temporarily assembled heat exchanger includes the steps of spraying an ionized fluid such as water on one surface. A powdered electrostatically charged flux is blown onto the opposite surface of the heat exchanger. A portion of the powdered flux is attracted to the one surface by the ionized fluid. Therefore, the flux material is uniformly spread across the heat exchanger. Finally, the heat exchanger is heated and brazed.
