Question

heat exchanger used in baffles explain?

Answer 1

The heat exchanger is a device in which heat is transferred from one medium to another separated by a solid wall, though in some cases the two mediums are in direct contact with each other, so that mixing occurs. Some common applications where a heat exchanger is used are: refrigeration, air conditioning, space heating, and power plants.
Baffles are flow-directing or obstructing vanes or panels used in heat exchangers.
