I intend to put a belly scoop on my rv-8.
after checking out some snowmobiles I have been playing with the idea of
mimicking their radiant cooling. I was thinking about plumbing the belly
scoop by running say 6-8 parallel 3/8" tubes along the belly the 7' back to the
scoop
Hi Kevin;
I forgot that I'd promised to send some dimensions of
snowmobile coolers. I just measured mine and it is 41.5"x9"x5/8". I wouldn't
consider using anything like this as a sole means of cooling, but if you are
mounting a belly scoop for a rad further back than I can imagine that 1 or
2 of these riveted to your belly would provide an efficient means to plumb
the coolant down and back again. This cooler in my current sled is one piece
with flow down and back, with both both inlet and outlet at one end only, but it
would be quick aluminum weld job to modify. My previous sled had two separate
coolers running parallel with a short hose coupling them under the end of the
seat, to provide a flow down one and back up the other. These hose connections
were out the top, so would be located through the skin and inside the belly of
your plane to provide a neat, tidy installation with no visible plumbing. These
coolers are very robust, so I wouldn't have any concerns about them withstanding
anything we can throw at them. If you
really want to go this route, I could try to find a set for
you.
I recall that some boats that have a fresh water cooling
system use a very similar heat exchanger that is mounted to the bottom of the
boat. In your area, these should be far more common.
Did you talk to Ken Welter about these snowmobile
coolers?
