Weatherproofing your P10
« on: May 08, 2016, 12:25:20 AM »
Working on a 12 Panel (3Wx4H)  P10 display and Tune to sign box....designing an enclosure with a plexiglass front, sealed.  Do I need to circulate air in the front?  I've already got the back compartment covered, but what about the front.  I will have a 1/4" gap between the P10 & Plexiglas.  In my design, air circulation would be cumbersome, but possible, but is it needed??

Comments, suggestions, or best practices are welcomed.

Last year I ran a 20 (4X5) P10 matrix that was mounted above the garage door. It has 2 - 40 amp 5v power supplies plus the BBB. The front is lexsan, PVC board 1X6 frame (painted black) and foam panel (Lowe's) backing. I left it on, non-stop, from late November to New Year's Day. I had no trouble with any overheating or part(s) failure. I live in Humble, Texas (north of Houston) and it stays warm here.

Thanks tomwb301, that will cover my Christmas show, but I'm concerned with summer too.  (4th of July as example) Although it won't be running in daytime (maybe 110) Eve's could be 80's. Hope Humble isn't there winter.  My focus is the heat generated by all those LED's.  Without some ventilation between the panel front and plixyglass, will heat build?


Your thoughts for 85 degrees

It's not the P10 panels so much. Think about they are not all on all of the time so they really can't get that hot. the most heat would be generated by the power supplies, they are on all of the time. If the PSU have a fan in them you should be good. I used one of these in a larger cabinet I built that holds all kinds of stuff for my show.

Yeah, got the back ventilated with fans from a scrapped desktop. They are 12V, but a $0.99 "DC-DC Step-up Module" will fix that.

For the front, I guess I'll not do anything special.  Thanks for the info.

Do you not have any gap at the top or bottom for air flow?  Even a small gap would allow convection air flow from bottom to top across the front of your panels.  These panels are black and will get VERY hot just from sunlight.

Aesl1982: the bigger the more they weigh. It wasn't hard to build, Capt. Murdoch copied what I had done and it works fine.

Just added one more pic...the stand.

Weight is a manageable 35# - Hardwood construction.
Should have used 1/4 ply for back, but didn't have, so I just used the 1/2" I had.  ( A weight mistake. )

Gotta build a handle on top to help carry it.  But needs to be removable, so it doesn't grow feet.

Great job on the enclosure!  Looks like you put some good thought as well as work into it.

That should work and hold up for some time.
