2. Fin (extended surface) - Wikipedia

   en.wikipedia.org/wiki/Fin_(extended_surface)

   This is the ratio of the fin heat transfer rate to the heat transfer rate of the fin if the entire fin were at the base temperature, = ˙. in this equation is equal to the surface area of the fin. 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 ...

3. Heat transfer through fins - Wikipedia

   en.wikipedia.org/wiki/Heat_transfer_through_fins

   The fin material should preferably have high thermal conductivity. In most applications the fin is surrounded by a fluid in motion, [ 1 ] which heats or cools it quickly due to the large surface area, and subsequently the heat gets transferred to or from the body quickly due to the high thermal conductivity of the fin.

4. Heat sink - Wikipedia

   en.wikipedia.org/wiki/Heat_sink

   A second type of heat sink fin arrangement is the straight fin. 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 ...

5. Plate-fin heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Plate-fin_heat_exchanger

   A plate-fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids, most commonly gases. It is often categorized as a compact heat exchanger to emphasize its relatively high heat transfer surface area to volume ratio.

6. Annular fin - Wikipedia

   en.wikipedia.org/wiki/Annular_fin

   In thermal engineering, an annular fin is a specific type of fin used in heat transfer that varies, radially, in cross-sectional area. Adding an annular fin to an object increases the amount of surface area in contact with the surrounding fluid, which increases the convective heat transfer between the object and surrounding fluid.
