A plate finned type heat exchanger is made of layers of corrugated sheets separated by flat metal plates, typically aluminium, to create a series of finned chambers. Separate hot and cold fluid streams flow through alternating layers of the h eat exchanger and are enclosed at the edges by side bars.
Thermal design of large plate-fin heat exchanger for Feb 25, 2017 · Large PFHE which is also called Brazed Aluminum Plate-Fin Heat Exchanger (BAHX) or Brazed plate heat exchangers (BPHE) consists of a stack of alternate flat plates called parting sheets and fin corrugations, brazed together as a block shown in Fig. 2. The streams flow along the passages made by the corrugations between the parting sheets.
fin heat exchanger design. A mathematical model of plate-fin heat exchanger design is proposed to consider fin type selection with detailed geometry and imposed constraints simultaneously. The concept of mix-and-match fin type combinations is put forward to include all possible fin type combinations in a heat exchanger.
