Construction. A brazed aluminium plate-fin heat exchanger (BAHX) comprises a block or core with flow passages separated by flat plates known as parting sheets.The edges of the flow passages are sealed by side bars.Secondary heat transfer surface, or finning, is provided by sandwiching corrugated sheets (with the corrugations aligned with flow) between the parting sheets.
Brazed Aluminum Heat Exchangers (BAHX), which are mission critical for a wide variety of cryogenic processing applications where reliability and thermal efficiency are paramount. Charts heritage begins with the adaptation of the product from the aerospace industry in the 1950s. Plate Fin Heat Exchanger - Aluminum Plate and Fin Heat Advanced Coil designs and manufactures flat plate fin heat exchangers with half-hard temper aluminum (0.016, 0.025, 0.032 or 0.040 thick) because of the thermal performance and the hardness properties of these materials are able to withstand 3,000 psi pressure washing, foot traffic, and general mishandling that would typically damage most radial or plate fin coils.
Introduction. Brazed Aluminium Plate-Fin Heat Exchangers are very compact exchangers built to a high specification for use in air separation plants and a wide range of other petrochemical and refrigeration applications. ALPEMA is the Aluminium Plate-Fin Heat Exchanger Manufacturers' Association, which currently represents the world's five major manufacturers of brazed aluminium plate-fin heat exchangers
