Hi Frank,
It's body heat + exhaled breath heat.
I have a polystyrene full size model of the inside of the sub that I sit in
occasionally
and know that it heats up quite quickly. I'm going very small so what
may be a problem
to me mightn't be for bigger subs.
It's difficult to determine what's going to happen temperature
wise.
I may try and get Brent involved as his comments sent me on this
path.
The transmission cooler I'm considering is only 280 x 140 x 19 mm + fan. If
I need it it's there.
If I don't design it in I won't have room later. The intakes will add to
the aesthetics.
Also if it's a total waste of space I can insulate it, sterilize
it, put an air line on the intake
and one of those beer dispensing guns they have in pubs on the outlet. and
fill it with beer.
This latter idea may get me a nomination for the psubs "HALL OF FAME
AWARD"
Thanks for your thoughts
Alan

Hi Allen. That water temperature should cool your sub fine. I can see
where someone in the Caribbean and was sitting on the surface a long time
would need cooling, but even there, it gets cold when you go deep.
I remember seeing the " Dry Dive " sub pictures, and he has a lot of
big, flat windows. A really nice little sub for sure. I'd love to go for a
ride, but I wonder if the heat inside is from prolonged maneuvering on the
surface.
I've always heard that sub riding is cold, and you need to wear your
woolies when you go down.
Even an ambient sub running at shallow depth like 30 feet or so should be
cool. I mean, where does the heat come from except body heat. Maybe a little
is put off by onboard electronics, more yet if you have inboard motors running
the thrust. I can't think of anything that actually creates a lot of heat
inside. Am I missing something ? I hope so, then I wouldn't need to add any
heaters.
