Finned tube surface area calculation
WebFeb 2, 2011 · The principle component of an ACHE is the tube bundle, of which there may be many, normally comprising finned tubes terminating in header boxes. The fins are most commonly spirally wound aluminum strips 12.7 × 10 −3 m or 15.9 × 10 −3 m high and with 275 to 433 fins/m. There are two main types of wound fin which are usually known as L … WebThe objective of a heat exchanger may be to recover or reject heat, or to sterilize, pasteurize, fractionalize, distill, crystallize, or control a fluid or process fluid. Tubular heat exchangers consist of small tubes located within a cylindrical shell. These finned pipes are positioned within a cylinder as a bundle, allowing various gases or ...
