There is about 1540 fins. Every one of them is 4mm long and 20mm high so that should be 1/12500m2. Total surface is then 0.1232m2.
Temp=30W/(0.1232m2 x 235W/mk)=1.036K
Is that right?
I have 120mm x 120mm x 27mm aluminum radiator, pump can push 106l/h, fan on radiator can push 126.55 m³/h. Liquid in system is water. I need to cool 30W laser with it. How much power can be removed. Laser tube is 700mm long, made out of glass and water flows around 15mm wide inner glass tube...
