About a month ago I asked you guys how to fix the heating problem behind my panel. I took the advise and installed a couple of 4" fans.
DigiKey has a pretty incredible filtering tool on their website and I used it for selecting a couple of fans. I picked a low rpm fan as I didn't
want a lot of noise and they easily exceed the cfm that would be required to displace the air behind the panel. They also have a very large
supply of different style fan screens. My biggest challenge was installing these in a finished panel. What you don't see in the pictures is that
I removed my displays and put towels behind the panel to keep metal shavings from mucking up my avionics.
First I made a template out of a piece of fiber board that I purchased at Hobby Lobby. I cut out the exact size of the fan and then drilled the
holes for mounting the fan.
I used a 1.5" knock out punch for the holes:
At this point I cleaned up the circle and reduced the sharp edges. I also made sure my glare shield cover also had matching holes and then attached the screens glare shield and fans together.
The glare shield material is actually a form of velcro that is used on convention displays. It looks really nice and stuff will stick to it.
