Conduction, convection and radiation - Heat transfer

WebThe primary mechanisms used for cooling electrical enclosures are as follows: Conduction: This is the transfer of heat through a solid. For example, heat generated inside an enclosure is transferred to the outer surface by means of conduction. Convection: Convection is the transfer of heat from a surface by means of a fluid such as air. WebSep 18, 2024 · The three types of heat transfer differ according to the nature of the medium that transmits heat: Conduction requires contact. Convection requires fluid flow. Radiation does not require any medium. Conduction is heat transfer directly between neighboring atoms or molecules.
