Class of Heat Exchangers Design

• Heat Exchangers are the devices that are
  primarily used to transfer or pass heat from one
  fluid to another fluid without the fluids making
  direct contact. Their main function is to
  transfer thermal energy between solid surface and
  a fluid, between solid particulates and fluid or
  between two or more fluids.
• Heat Exchanger is used for both heating and
  cooling and usually is used for cooling. There
  are different types of heat exchanger available
  which are characterized according to nature of
  heat exchange, and direction of flow.

The common type of heat exchanger includes Shell
and Tube Heat Exchanger, Plate Heat Exchanger,
Regenerative Heat Exchanger, Adiabatic Wheel Heat
Exchanger. They all are effective in variety of
heat transfer applications.  Although Shell and
Tube Heat Exchanger is considered as the most
efficient and important heat exchanger. Shell and
Tube Heat Exchanger are mainly used in chemical
process industries, conventional and nuclear
power station, steam generator and almost in
every type of industry.

The Shell and Tube Heat Exchanger consists of a
set of tubes (called the tube bundle) which are
mounted inside a cylindrical shell. Basically,
these are used for high pressure application. 
Two fluids can exchange heat, one fluid runs
through the tubes (called Tube Side Fluid) and
another fluid runs over the tube (called Shell
Side Fluid) inside the shell.

The fluids can either be a gas or a liquid.
Shell and Tube heat exchanger is considered as a
versatile heat exchanger as it uses large heat
transfer area, using waste heat and can be
cleaned easily. This is an efficient way to
conserve energy.  Source http//sunkaier.blogsp
