Hi 

I have read that some people have put a fan into the baggage back bulkhead (6B12-2) of their XL's.



What type of fan and does it work well? I was thinking of a 12v computer 

power supply fan of about 4 ".  In our Hot Aussie summers I think I will need something during taxi. ram air should work once airborne.



Anyone got any Ideas or done something similar?

I have installed two cpu type muffin fans in my Zodiac XL. The bad news is that it isn't finished so I don't yet know how well they will work. Here's what I do know;



They are available in lots of sizes and standard cubic feet per minute (scfm) capacities. 



I put a 4" 35 scfm model in the aft baggage bulkhead of my plane. My purpose was not to keep us cool under the bubble canopy on the ground. I really don't think it will move enough air to make a significant difference in that situation. What I think it will do is moveenough air while parke doout in the sun at a fly-in to keep the cockpit from becoming a broiler. Ata destination airport, I would use a canopy cover to reflect most of the sun's energy, but at a fly-in it will sit there like a greenhouse so the few hours of minor electrical drain may prove useful. I'll find out later but right now it's a guess.



What I will use during taxi is a custom made strut to support the canopy in an open position until run-up and take-off.



The second fan is under the C-channel from the bottom center of the panel to the firewall stiffener. I mounted it there to cool the avionics which would otherwise sit in an upside down bowl of captured heat under the forward top skin. I may decide later on to drill some vent holes in that forward top skin just inside the canopy to use that avionics heat to defrost the front of the canopy if I see the need.

Ed, I put one of those little computer fans in the top forward skin, just to move a little air behind the panel and maybe do a light canopy defogging.  Like yours, it is not battle-tested.

I have also been pondering the problem of keeping the cockpit cool when the 

plane is parked in the sun. My flight instructor always put a reflective 

sun screen in his C-150's windshield when it was parked in the sun. For 

years I've used, in my cars, the reflective screens that are made of thin 

blister packing material sandwiched between foil. These work amazingly 

well. I'm thinking of buying the largest one I can find for a car, cutting 

it to fit the outline of the canopy-fuselage seal, and using sticky Velcro 

to hold it in place. I might need to cut it into 2 sections for easy 

storage. The extra large one we have in our car weighs 13 oz.



Has anyone tried this approach with a 601? It seems a lot simpler than a 

fan or a canopy cover.

Hi Chris;

Computer fans work very well in this application. You might even 

consider using 2 of them. I have only one at present. On really hot days 

, more air is welcome.

Terry, if you cannot find a large enough sunscreen for

an automobile, the screens are made from a insulating

material known as Astrofoil.  



Astrofoil should be available in rolls from a home and

building store such as Home Depot or Lowes.  It comes

in several different widths as legnths.  It's been a

while since I bought some but the price was not too

bad if I remember correctly.



Hope this helps

Chris--

   I installed a 2 inch one in the forward panel above the instruments and a 6 inch one at the rear of the baggage compartment. They have come in handy for defogging and do assist with some cooling.  The only real way to cool the cockpit when stopped or taxing, however, is to pop the canopy up a bit

I prop open the canopy while taxiing. I made a prop that keeps the canopy partly open and prevents it from blowing open in the wind. This keeps the cockpit reasonably cool during taxi. I have a canopy cover from Bruce's Custom Covers that does a good job of keeping the cockpit cool when parked. I recently added a Koger sunshade and a couple of Vista Vents to help keep the cabin comfortable in the air on very hot days.

Are those computer fans 12VDC.  Wouldn't think  they would run off the computer power supply that they are cooling.  bob U.

Yes they are 12vdc, this is available on a desk top PC power supply.

Nearly every circuit in a personal computer runs on 12VDC or less. Most of the circuits run on 5VDC or less.

I used a 12 volt computer fan.  I got it off of EBay.  It works fine. 

Doesn't pull a lot of air.  But it does get some movement.  Which should 

help
