Yup, just a brief on this subject.

Heat exchangers are devices used to transfer heat energy from one fluid to another, gas to gas or gas to liquid. 

Typical heat exchangers are seen around in most unexpected location. From household appliances as air conditioners, refrigerator etc.  Boilers and condensers in thermal power plants are examples of large industrial heat exchangers. There are heat exchangers in our automobiles in the form of radiators and oil coolers.  Heat exchangers are also abundant in chemical and process industries.

Heatexchanger sizes varies from couple of square mm (heat sink in computer cpu) to length exceeding hundreads of square meters!

From simple study flow to complex flows.

Heat exchanges as they say “comes in all sizes and nearly for all duties”

We will, in my next post discuss about fundamental of heat exchangers.
