Fan Curve and Plenum

First-pass trade studies determining the flow in a finned plenum with a fan and given fan curve. 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 fan curve.

Outputs: 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 i 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.
