Standard Heat Sinks
Thermal resistance is calculated based on the footprint of the heatsink. A uniform source centered on the heat sink which
covers 80% of the heatsink footprint is applied. If you have distributed loads, then you can expect 10% better performance
in natural convection and 20% better performance in forced convection.
Thermal data is based on a 100mm long extrusion.
For natural convection the gravity vector is aligned along the length of the fin unless otherwise mentioned.
