Fan Curve and Plenum
First-pass trade studies determining the fan curve needed to meet the target flow in a finned plenum. Intended for preliminary sizing and sensitivity analysis; validate independently for safety-critical use.

Model summary
Inputs: Plenum size, finned heat sink dimensions, fan inlet size and position and required flow.
Outputs: The required fan curve, plenum flows. Plenum top gap, side channel and heat sink fin channels. The fin channel for is given over the length of the channel
Fan Curve: the fan curve operating point is determined.
Use case: quick what-ifs, sensitivity, and early sizing—not detailed CFD/FEA.
Examples
Example of a finned heat sink in a plenum with a fan.
Preliminary estimates only. Verify independently for safety-critical applications. See Terms.
