Hi Frank
My sub doesn't exist yet.
The water surface temperature is 57 - 69 round where I am, so it's a bit
hotter down here.
My fear of cooking comes from a conversation with Brent Shaw who has a 3
man metal ambient sub
"Drydive". He says it reaches body temperature reasonably quickly.
My over riding design mandate was to go small, so I'll be more prone to
overheating. I'm also placing
my motors within the hull and making the hull of fiberglass.
The radiator may remove condensation from the air.
Brent coats his ports with an anti fogging product, I guess you'd have to
be careful that any product is
compatible with the acrylic.
Picked up two linear actuators last week and are making a jig to test
them today.
regards Alan.

cooled ambient sub
Hi Allen. I don't have any advice on how to cool a sub, but I do have a
question. Where is all that heat coming from. Typically a boat sitting in the
water is fairly cool next to the hull, even on hot days where up on deck it's
sunny. I would think a small sub, be it ambient or not, would need additional
heat rather than cooling. Now the water temp. here in Calif. is cold anyway.
Usually between 54 and 56 degrees year round, so I was planning on adding some
type of heater, to help control the temp. and also evaporate some of the
moisture. I've seen where condensation on the view ports can be a problem, and
requires constant wiping with a rag. That would probably scratch the plexi
over time, not good.
Anyway, how come your sub is so hot ? Frank D.
