Heat Exchanger


A heat exchanger is a piece of equipment that continually transfers heat from one medium to another in order to carry process energy. There are two main types of heat exchangers.
  • Direct heat exchanger, where both media between which heat is exchanged are in direct contact with eachother. It is taken for granted that the media are not mixed together.
An example of this type of heat exchanger is a cooling tower, where water is cooled through direct contact with air.
  • Indirect heat exchanger, where both media are separated by a wall through which heat is transferred.
An example of this type of heat exchanger is a plate heat exchanger, where the two fluids of heat exchange are separated by the plates within the unit.
