Heat Transfer Through Fins

by / Tuesday, 28 March 2017 / Published in Technical Corner

Convection heat transfer between a hot solid surface and the surrounding colder fluid is governed by the Newton’s cooling law which states that “the rate of convection heat transfer is directly proportional to the temperature difference between the hot surface and the surrounding fluid and is also directly proportional to the area of contact or exposure between them”. Newton’s law of cooling can be expressed as
Qconv = h A (Ts )
Where, h = convection heat transfer coefficient
Ts = Hot surface temperature
= Fluid temperature
A = area of contact or exposure
