Plate fin heat exchangers (PFHE) is compact, low weight and high effectiveness are widely used in cryogenic applications. Normally PFHE is made of a stack of corrugated fins alternating with nearly equal number of flat separators known as parting sheets, bonded together to form a monolithic block. Feed and exit headers are welded to provide the necessary interface with the inlet and the exit streams. While aluminum is the most commonly used material, stainless steel construction is employed in high pressure and high temperature applications.
This following thesis "Design of Compact Plate Fin Heat Exchanger" by JAINENDER DEWATWAL is rather interesting for those who would like to have brief idea about PFHE and methodology for PFHE calculation. Several correlations such as MANGAHANIC, WIETING, JOSHI &WEB, DEEPAK & MAITY have been used in the calculation. For those who are new in PFHE design, this may be good source to start...
