How is heat energy transferred
WebIf two molecules collide, an energy transfer from the hot to the cold molecule occurs. The cumulative effect from all collisions results in a net flux of heat from the hot body to the colder body. We call this transfer of heat … WebCooling an electrical enclosure involves processes for transferring heat from inside the enclosure and discharging it to the surrounding air. Various heat transfer mechanisms exist, including convection, conduction, thermal radiation, and evaporative cooling. Types of Heat Transfer Mechanisms
