I’m wondering if anybody can check my calculations please. I need to attach suitable heat sinks to some mid powered LED lights.
The product i’m looking at is ATS-EXL63-300-R0
My calculations are below.
Sorry, I tried the applications engineering section in the live chat but they suggested I post on the forum.
Many thanks in advance folks. Hopefully somebody can confirm as it’s all pretty new to me.
R natural convection °C/W = 13°/W
(data taken for 1 inch of material (25.4mm))
Extrusion is 300mm long, (11.81inch), so °C/W will be 13/11.81 = 1.1°/W
Considering I want to keep everything below max 90°C for longevity of parts and efficacy, 90/1.1 = 81.8W max.
Is this correct??
