Folks,

I would really appreciate your help and advises on the following matter,

I have a sealed fiber reinforced plastic enclosure (1m x 1m x 0.4m) which is kept outdoor. Suppose the average outside temperature is 40 degree celsius, I would like to know what will be the temperature inside the enclosure. What all thermal loads should I take in to consideration?

Can somebody give me a rough idea on how to sort this out.

Regards,

Krishna
