Heat exchanger
A
heat exchanger
is a device used to transfer heat between one or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in
space heating
,
refrigeration
,
air conditioning
,
power stations
,
chemical plants
,
petrochemical plants
,
petroleum refineries
,
natural-gas processing
, and
sewage treatment
. 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
.
