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.
Also found in: Acronyms, Wikipedia. Heat transfer. Heat, a form of kinetic energy, is transferred in three ways: conduction, convection, and radiation. Heat transfer (also called thermal transfer) can occur only if a temperature difference exists, and then only in the direction of decreasing temperature. Beyond this, the mechanisms and laws governing each of these ways are quite different. See Conduction (heat), Convection (heat), Heat radiation. By utilizing a knowledge of the principles governing the three methods of heat transfer and by a proper selection and fabrication of materials, the designer attempts to obtain the required heat flow.
