A piece of equipment built for 
efficient heat transfer from one 
medium to another.
? A heat exchanger is a piece of equipment 
built for efficient heat transfer from one 
medium to another.
? They are widely used in space heating, 
refrigeration, air conditioning, power plants, 
chemical plants, petrochemical plants, 
petroleum refineries, natural gas processing 
and sewage treatment.

? In parallel-flow heat exchangers, 
the two fluids enter the exchanger 
at the same end, and travel in 
parallel to one another to the 
other side.

? In counter-flow heat exchangers 
the fluids enter the exchanger from 
opposite ends. The counter current 
design is the most efficient.

? In a cross-flow heat exchanger, 
the fluids travel roughly 
perpendicular to one another 
through the exchanger.
