It is the ratio of the fin heat transfer rate (˙) to the heat transfer rate of the object if it had no fin. The formula for this is: = ˙,, where , is the fin cross-sectional area at the base. Fin performance can also be characterized by fin efficiency. See more In the study of heat transfer, fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection See more To create a tractable equation for the heat transfer of a fin, many assumptions need to be made: 1. Steady state 2. Constant material properties (independent of temperature) 3. No internal heat generation See more Open cavities are defined as the regions formed between adjacent fins and stand for the essential promoters of nucleate boiling or condensation. These cavities are usually utilized to … See more If the fin has a constant cross-section along its length, the area and perimeter are constant and the differential equation for temperature is greatly simplified to See more The base of the fin is typically set to a constant reference temperature, $${\displaystyle \theta _{b}(x=0)=T_{b}-T_{\infty }}$$. … See more Fins are most commonly used in heat exchanging devices such as radiators in cars, computer CPU heatsinks, and heat exchangers See more
