I am looking at a weather proof enclosure for some electronic gear. It will be fairly small, smaller than a breadbox (slightly smaller than a shoebox in fact, around 8" x 6" x 3") and have a clear plastic front so a display can be seen. The electronics inside will dissipate around 5 watts. But I'm more concerned with solar heating. I can't seem to find any info on what temperatures I might expect inside the box.
I'm looking at using an e-paper display which is only rated for use up
direct sunlight in the US. Even here in the mid-Atlantic area surface temps (for example a sidewalk) can be too hot to touch which is likely
temperature. I'd hate to require the unit be kept in the shade. A big advantage of using e-paper displays is their high visibility in direct sunlight.
Anyone have experience with similar units?
