TYPES OF HEAT EXCHANGERS
Summary
The important information from this chapter is summarized below.
Types of Heat Exchangers Summary
There are two methods of constructing heat exchangers:
plate type and tube type.
Parallel flow - the hot fluid and the coolant flow in the
same direction.
Counter flow - The hot fluid and the coolant flow in
opposite directions.
Cross flow - the hot fluid and the coolant flow at 90
angles (perpendicular) to each other.
The four heat exchanger parts identified were:
Tubes
Tube Sheet
Shell
Baffles
Single-pass heat exchangers have fluids that pass each
other only once.
Multi-pass heat exchangers have fluids that pass each other
more than once through the use of U tubes and baffles.
Regenerative heat exchangers use the same fluid for
heating and cooling.
Non-regenerative heat exchangers use separate fluids for
heating and cooling.
