Hi groupWe are thinking about mounting four baby 30mm cooling fans flush with the top surface of the instrument module. Two above comm and transponder and two above dynon D10A. Figure they would help get a little heat out from under panel and perhaps help a little with demisting. Each fan moves ~ 3CFM.Any comments appreciated.Ron Parigoris   [quote][b]

Hi Ron,

I doubt that you need that many, I've got just one small fan installed, don't know how much air it moves, but it does quite a good job of de-misting.

About what size square is your single fan?

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Ron,

 No problem with only using one each fan.  D-10s need to stay below  120F so that should be fine.  As for GPS antennas, in the 4 or 5 I have  installed, it is best to fashion an aluminum piece shaped like a U for the  active antenna to sit on glued right to the top of the inside of the  panel.  The antenna sits in the trough of the U and provides a nice out of  the way place to stick it.  All the Garmin, GRT, Blue Mountain  and Anywhere Map units work better with that little piece of  aluminum.  That technique was recommended by my Garmin Distributor.   It has always worked for me.  Try it...Doesn't cost anything but a thin 4  inch piece of aluminum.

Ron- 

  

I mounted my GPS antennas as Bud suggests but instead of aluminum, I wrapped a 2X4 with packaging tape and used it as a mold to make the brackets of BID.  I made one about 6 inches long, cut it into two three inches or so each and floxed both to the inside of the instrument panel.  I used one for the GPS antenna and the other for the satelliet radio antenna.  I cut my coax to about 18 inches so I can easily remove the GPS and still leave everything plugged in and powered up.

Hi Mau11

"if you have pictures of fan cooling installation I am interested."

I have a few different fans on order from Newark and Mouser to fool with. I will post details and pics once I get it all figured out.

As far as GPS placement, we fooled tonight with reception and for certain having an aluminium backing on antenna makes for better reception (thanks Bud for suggesting reception is better with a groundplane). I found that specifications for antenna reception on Garmin 296 is in fact with a square 70CM groundplane installed. Anyway I am going to use the aluminium bracket that came with antenna, removed the suction cups and drilled 3 holes to make a 3 legged stool out of it. Then I screwed 3 drawer wood pull handles to the bracket (handles have metal inserts) and shaped to fit inside bottom of top port side of instrument module. Once I have my cooling fans installed I canl JB KWIK in place 3 wood standoffs for antenna mount. Once JB KWIK is cured (4 minutes) will put a flox/Aeropoxy/30 minute hardener fillet around wood standoffs.

BTW we tested GPS reception tonight. We covered antenna with fiberglass (both epoxy and whatever ester instrument module is made out of), plexiglass and firewall pheonelic stuff. It degrades performance a little, but even covered with all this stuff as long as a groundplane was below antenna, reception was a tad better compared to the finger sized antenna connected direct to 296.

Ron, A single inexpensive fan mounted in the under surface of the  shelf 

(where it is out of sight above the passenger's legs), with a row of holes 

under the windscreen on pilot's side, has worked well as both cooler & 

demister for me. Regards, David Joyce, G-XSDJ

The attached is a view of the top of my panel.



The fan works well as a demister and removes any excess heat from the panel

The GPS aerial gets a very slightly better signal as it is not under the

panel

The mount on top is for the PCAS unit we have.



I hope this might give you some ideas.  BTW I have repainted it since this

picture was taken.

Hi Ron,

It was a 2" fan, very similar to Ian's in respect to size and location, intended for cooling, de-misting was a secondary consideration.
