Temperature Rise with AP in Enclosures
QUESTION ON HEAT RISE IN ENCLOSURES:
We are evaluating various enclosures for our residential deployment and have been shown a few "sealed" enclosures (no venting).
The question has arisen about heat buildup inside the boxes. To test this variable we ran an AP-125 inside one of the sealed enclosures for t he weekend. The AP appeared "cool".
We have a few applications where there are splash conditions (the monkey house and bus garage to name a few) and a sealed enclosure would be helpful there. For the residence halls we could drill vent holes but want to know if this is absolutely necessary before drilling literally thousands of holes..
Heat buildup in a non-vented enclosure depends on both the volume of the enclosure and the amount of power dissipated by the AP. Based on tests we've done where the AP was operating in worst-case conditions, the effects of this heat buildup can (for typical enclosures) be offset by reducing the maximum ambient operating temperature (temperature outside of the enclosure) to 40C (from 50C). If the ambient temperature does not exceed this, the AP will operate just fine in such an enclosure. The tests were done with Oberon 1055 and 1027 enclosures.
