I don't know any other data besides what I already mentioned. My questions are:
absorptivity of what? aluminum?
area 1 = ?
area 2 = ?
area 3 = ?
htc = ?
planck = ?
what's the difference between Tamb and Tair?
What's Tbox4?
Can you plug the numbers that I have already provided in your equation so...
Where I am coming from is Telcordia standard GR-487 specifies '+46 deg C as ambient temperature + solar load' for design of electronic enclosures. I am assuming solar load of 1120 W/m2 on the enclosure and want to know how much it translates to temperature as I want to specify the ambient...
Thanks 'IRstuff' and 'ione' for your inputs. Right now I am considering no internal heat load. What I want to know is if this equation still holds good - Q=A*K*(delta T)/L
where Q = Solar Load, A = area exposed to solar load, K = thermal conductivity of aluminum, delta T = temperature difference...
I have aluminum and fiberglass enclosures approx this size 12.2"x10.2"x6.25" (WxHxD) respectively. These enclosures will be installed outside and the solar load on them will be 1120W/m2. Consider the ambient temperature to be +55 deg C. So can someone tell me how to calculate the additional rise...
