Enclosed space cooling
Enclosed space cooling
(OP)
I wish to cool an enclosed space by insertimg holes into the outside surfaces to allow air to flow through. How big should the holes be (and how many), before I can assume that natural convection to an ambient outside temperature occurs?

To rephrase the question, what size openings do you need relative to the size of the container so that sufficient flow occurs for natural convection to ambient to be assumed on the internal surfaces, approximately? Radiation to ambient would obviously be partially blocked and can be evaluated.

Search the archives here for stack draft or chimney effect.
It is impossible for natural convection to ever cause the temperature inside to equal the temperature outside.
