Why Pin Fin LED Coolers Perform Better Under Tilted Position

Both LED coolers have a similar cooling performance under classic vertical position. In this experiment we mount the same LED module from Tridonic, the Talexx Stark spot light module STARK-SLE-G3-19-3000-830-CLA on both LED coolers with thermal grease as interface. This Zhaga book 3 LED engine generates 30 watt of power. In CFD thermal simulation we change the gravity orientation to get a first impression of the expected results. The gravity simulated angles are 0°, 50° and 90°.
