Heat transfer is the exchange of thermal energy between physical systems, depending on the temperature and pressure, by dissipating heat.The fundamental modes of heat transfer are conduction or diffusion, convection and radiation.eat transfer is the exchange of thermal energy between physical systems, depending on the temperature and pressure, by dissipating heat.
Convection heat transfer happens when a fluid such as air or water gets heated by a hot object that touches the air or water. Forced air furnaces are great examples of convection heat as the air moving over the heat exchanger gets warm and then passes that warmth to objects it touches once it is in the room.
