Yes it did surprisingly. If the box was equipment gray (I had 4 identical boxes) it would run hotter with a heat shield than the satellite white box with no shield.

Are you saying white paint outperformed heat shields? That's awesome info. I always thought heart shields were the best.

Add a thermostatically controlled ventilation fan 2. Put a heat shield up on the south side of the enclosure. This can be just a plate of aluminum, painted white on the sun side, and mounted to the enclosure with 1" standoffs We have a site like yours, and just the fan keeps the temperature below 120° F (49° C). I think if we added the heat shield we could drop it another 10° F. bp <part15sbs{at}gmail{dot}com> On 7/13/2018 4:51 PM, Sterling Jacobson wrote: I’ve got a few side of the house enclosures exposed to direct sunlight part of the day. Inside the electronics are about ready to melt. Like 90C+ CPU temps. These are about 3’ x 3’ x 12 deep or something like that, so not a lot of room. What are you guys using to keep these things decently cool? -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
