Seung-Kwon Seo Chul-Jin Lee, in Computer Aided Chemical Engineering, 2017. 1 Introduction. A plate fin heat exchanger (PFHE) is one type of multi-stream heat exchanger that is also known as a brazed aluminum heat exchanger (BFHE). The layers are manufactured by brazing in a furnace and separated from each other by metal plates and a specified configuration of fins.INSTALLATION, OPERATION, AND MAINTENANCE MANUAL Basic Components of a Chart Brazed Aluminum Heat Exchanger (BAHX) The Chart Energy & Chemicals, Inc.

Chart is a recognized global leader in the design andPLATE FIN HEAT EXCHANGERS - thermopedia Aluminum units use material AS3003 in the exchanger block. Braze material is AS3003 + silicon. Plates are purchased with a thin film of braze metal on both sides. The unit is built and placed in a vacuum furnace. The braze takes place under vacuum and at a temperature of 580C. The parts of the block are then firmly attached together.

Plate Fin Heat Exchangers utilize solid plates to conduct heat from one fluid flow path to heat transfer fins which then transfer heat to a second fluid. The heat transfer fin and plate construction add to the structural integrity of the heat exchanger, enabling it to withstand high pressures. This construction type also can contain large surface areas in relatively small heat exchanger volumes, which makes it
