Directional Radiative Cooling

Post  Alessio on Fri Jan 09, 2009 2:25 pm

I made some calculations on the efficiency of Directional Radiative Cooling (let's say De Salvo scheme). I calculated the coupling losses as a function of the extracted power and the waist of the cooling profile in the hypotesis that the profile has a Gaussian shape. Results are reported in the following figure, where the Log of the coupling losses is plotted.



It seems that the precision required on the profile dimensions is about +/- 2.5mm and that on the power is of the order of +/- 50mW.
