1.1 DESCRIPTION OF HEAT EXCHANGER TYPES
1.1.5 Types of Heat Exchange Equipment

A. INTRODUCTION

The role of Section 1.1, as a whole, is to introduce heat exchange equipment by way of a series of classifications, each from a different point of view. In this section, this purpose is prosecuted further by enumerating heat exchanger types, mainly from the viewpoints of function and construction. This section gives the names of the main types and highlights their special features.

B. SHELL-AND-TUBE NO-PHASE-CHANGE HEAT EXCHANGERS

Most “unfired” heat exchangers, operating with fluids that do not change phase, are of baffled shell-and-tube design, by which is meant that one of the fluids flows within straight or hairpin-bent tubes, whereas the other flow between and around those tubes, within an all-confining shell, being guided in its path by baffles. These baffles serve to hold the tubes apart, so that the shell-side fluid can flow between them; they also control the path of that fluid to some extent.

Many different designs are used; the choice depends on the relative importance, for the fluids and the application in question, of such factors as the following:
