Heat Dissipation

Definition - What does Heat Dissipation mean?

Heat dissipation is a type of heat transfer. Heat dissipation occurs when an object that is hotter than other objects is placed in an environment where the heat of the hotter object is transferred to the colder objects and the surrounding environment. Heat dissipation can occur through a variety of means.

Heat dissipation is closely related to energy dissipation. Energy dissipation is a measure of energy lost due to other forces. This can occur in many forms, such as kinetic energy loss caused by the forces of friction. Heat dissipation is simply a subtype of energy dissipation.

Heat can be dissipated through many different methods. One method that dissipates heat is convection, which is a transfer of heat through moving fluids. An example of this could be a convection oven that uses air (the fluid) to transfer heat. Another method is conduction, which allows heat to dissipate throughout a material and possibly into a different material that is in contact with the hot material. An example is an electric stovetop that is heated through electrical resistance. Finally, another type of heat dissipation occurs via radiation; this type of heat dissipation is illustrated by a microwave oven.
