A System Approach to Heat Exchanger Manufacture Using Fluxcoated Components
Published May 18, 2003 by Institution of Mechanical Engineers in United Kingdom
The present work discusses how brazing flux coatings based on organic coatings combined with fluoride-containing fluxes and salts can be utilized in a heat exchanger system. Formability, debinding of the resin, Health Environment and Safety (HES) and brazeability is discussed. It is shown that flux-coated products can be customized to be compatible with forming and fabrication operations used for each component in heat exchanger manufacture. The benefits from reduced use of flux and, more specifically for new CAB installations, the potential for substantial reduction in capital expenditure due to the elimination of the need for inline fluxing are discussed.
