DIFFERENT TYPES OF WINGED HEAT EXCHANGERS: A BRIEF STUDY

Abstract

The heat transfer surface is a surface of the exchanger’s core that is in direct contact with fluids and through which heat is transferred by conduction. That portion of the surface that is in direct contact with both the hot and cold fluids and transfers heat between them is referred to as the primary or direct surface. To increase the heat transfer area, appendages may be intimately connected to the primary surface to provide an extended, secondary, or indirect surface these extended surface elements are referred to as fins.
