A heat exchanger is a piece of equipment 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. They are widely used in space heating, refrigeration, air conditioning, power plants, 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.

Famous quotes containing the words heat and/or exchanger:
“Nowadays men cannot love seven night but they must have all their desires: that love may not endure by reason; for where they be soon accorded and hasty, heat soon it cooleth. Right so fareth love nowadays, soon hot soon cold: this is no stability. But the old love was not so.”
—Thomas Malory (c. 1430–1471)
“I want to know whether you are a person devoted to creating or to exchanging in some respect or other: as a creator you belong to the free, as an exchanger you are their slave and instrument.”
—Friedrich Nietzsche (1844–1900)
