Heat Exchangers

KEY CONCEPTS
  • The transfer of thermal energy between fluids is one of the most important and frequently used processes in engineering.

  • The transfer of heat is usually accomplished by means of a device known as a heat exchanger.

  • Common applications of heat exchangers is the power plants with boilers, fan coolers, cooling water heat exchangers, and condensers.

8.1 CLASSIFICATION OF HEAT EXCHANGERS

Heat exchanger is a device, whose primary purpose is the transfer of heat energy between two fluids. Heat exchangers are classified into regenerators, open-type exchangers, and closed-type exchangers or recuperators. Regenerators are heat exchangers in which hot and cold fluids flow alternately through the same space with as little ...
