Hi Alan: I belong to a number of small-car newsgroups, and the subject of cooling comes up frequently since many of the cars discussed have engines not designed to support A/C. While you're idea has merit, and will work to some degree, I don't think you'll get the amount of cooling you'll require out of this system unless you're diving in some really cold water... and always moving forward. One solution many people go with is using an ice-chest packed with ice & water and a pump to circulate the cold water through a small radiator. Take a look at the following link: http://www.instructables.com/id/Portable-12V-Air-Conditioner---Cheap-and-easy!/ In the confines of a small sub, this should cool you quickly. And once you're underwater, you should be able to either turn it off or run it occasionally.

While talking with a fellow member on Saturday, he
informed me that it got hot really fast in his metal ambient sub. And that
he had his air supply blowing round his head for cooling.
As I'm making a much smaller fiberglass ambient
sub, I'm figuring I'll get even hotter.
What I'm considering is having a forward water
intake on both sides of the hull to an aluminium radiator or transmission oil
cooler, with the outlets placed near the thrusters to create water
movement. There will be intake filters, taps and a thermostatically controlled
fan in the system. I'll flush it out after each dive.
Does this idea have any merit?
Any experience, thoughts or adverse comments will
be appreciated as it will be a lot of mucking about evaluating it outside the
sub. And I can't put it in later.
I'm not sure of the size, it could be a 280mm x
180mm transmission cooler , a 280mm x 180mm radiator or anything in
between. If anyone has thoughts on the
size that would be appreciated too.
Thanks,
