EXTENDED SURFACE HEAT TRANSFER - Thermopedia

The fin temperature effectiveness or fin efficiency is defined as the ratio of the actual heat transfer rate through the fin base divided by the maximum possible heat transfer rate through the fin base, which can be obtained if the entire fin is at base temperature (i.e., its material thermal conductivity is infinite). Since most real fins are ...

Cooling 101: The Basics of Heat Transfer - Koolance

Cooling 101: The Basics of Heat Transfer Moving Heat. As the First Law of Thermodynamics implies, matter and energy can not be created or destroyed (only converted between the two). Likewise, heat--the movement of energy from a hotter object to a cooler object--is never eliminated, but only moved elsewhere. This is the role of all cooling systems.

Air cooling - Wikipedia

Air cooling is a method of dissipating heat.It works by expanding the surface area or increasing the flow of air over the object to be cooled, or both. An example of the former is to add cooling fins to the surface of the object, either by making them integral or by attaching them tightly to the object's surface (to ensure efficient heat transfer). In the case of the latter, it is done by ...
