Ceramic fin is one type of heating element used in heaters. These units contain a solid block of ceramic material with metal fins attached. An electric current heats the block, which in turn heats the fins. The fins then heat the air. In another type of heating element, the honeycomb disk, the block of ceramic is perforated with numerous holes ...
The fin efficiency will always be less than one, as assuming the temperature throughout the fin is at the base temperature would increase the heat transfer rate. The third way fin performance can be described is with overall surface efficiency,
Fins are extensions on exterior surfaces of objects that increase the rate of heat transfer to or from the object by increasing convection.This is achieved by increasing the surface area of the body, which in turn increases the heat transfer rate by a sufficient degree.
A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees Celsius. [1] They are used to provide heat for a process or can serve as reactor which provides heats of reaction.
A variation on the straight fin heat sink is a cross-cut heat sink. A third type of heat sink is the flared fin heat sink, where the fins are not parallel to one another. Flaring the fins decreases flow resistance and makes more air go through the heat-sink fin channel; otherwise, more air would bypass the fins.

A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage.
