VI. Heat Exchanger
Introduction of Heat Exchangers
Basic Types of Heat Exchangers (Chap. 8.2)
A heat exchanger is a device in which heat is transferred between a warmer and a colder
substance, usually fluids. There are three basic types of heat exchangers

Part I. Introduction to Heat Transfer
Heat is a form of energy
Energy is the ability to do work. Energy takes many forms, including heat, light, chemical,
electric, mechanical, atomic, sound, etc.
Heat Transfer
Heat transfer is related to but different fr

Assumptions: steady state, radially symmetric (no variation/activity in the direction),
infinite cylinder (implying no z dependence), constant k.
