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.
Table of specific heat capacities at 25 °C (298 K) unless otherwise noted. [citation needed] Notable minima and maxima are shown in maroon.

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 ...
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 ...
A heat sink usually consists of a metal structure with one or more flat surfaces to ensure good thermal contact with the components to be cooled, and an array of comb or fin like protrusions to increase the surface contact with the air, and thus the rate of heat dissipation.
The next day, she said she woke up feeling "very weak" like she couldn't walk. She'd had plans to travel to Las Vegas to film a commercial, and a family member drove her there from her home in L.A ...
