What is Heat Exchanger?
Heat exchanger is a device built for efficient heat transfer from one medium to another.
The media may be separated by a solid wall, so that they never mix, or they may be in
direct contact.
The classic example of a heat exchanger is found in an internal combustion engine in
which a circulating fluid known as engine coolant flows through radiator coils and air
flows past the coils, which cools the coolant and heats the incoming air.
Working Principle:
Heat exchanger works at naturally flows from higher temperature to lower temperature.
Hot fluid and cold fluid are separated by a heat conducting surface.
Heat can be transfer from hot fluid to cold fluid without any external work.
Applications:
They are widely used in:
Refrigeration
Air Conditioning
Power Plants
Chemical Plants.
