[MLB-WIRELESS] AP Box cooling

[PèéJäy]

MessageTry adding a bigger heatsink to the regulator and it should keep working up to ~80-100deg.  It think it may shorten the lifespan a bit but by the time it dies it will be time to upgrade anyway.... Also try putting some type of shade device around the unit to keep it out of direct sunlight. This will reduce the temp by a fair bit.

  Has anyone added a cooling system to their AP box?

  I have a DWL-900AP+ in a box, up a pole on the roof. I have also put a couple of temperature sensors (DS1820) in the box. One is near the regulated power supply (and so it gets a little warm) and one is near the at the bottom of the box. The problem I can see coming this summer is that when the sun hits the box the temperature inside is going to get rather high. It has already got as high as 42 degrees C while the outside air temp is only around 17 C.

  When summer comes and the air temp is over 30, what is it going to be like in the box? The DWL-900AP+ is rated to work up to 55 C (I think), but I don't really feel like seeing how hot it can get before it shuts down. 

  Has anyone added a fan or other cooling device to their AP box? 

  Regards,
