  Hi David,
  my radiator idea might work for an ambient but in a 
  1 atm sub
  the radiator would blow apart with the water  
  pressure if too deep.
  You could run the water in to a reservoir 
  & suck it up through the radiator
  with a pump between the radiator & the outlet but it 
  would drain the electricity
  pumping against the outside water pressure & be a 
  bit dodgy.
  I was rethinking the heat issue also after seeing 
  Doug's sweat box.

Vance,
 
   Take the time to give Alan's 
    idea a look...makes better sense to use the cold water and simply reuse it 
    with a pump. A great how-to set of instructions 
    too.

Dave, 
    
    That is almost exactly the semi-stone age air conditioning unit that 
    Wil and Charlie Kohnen install on all the Seamagine subs. It works like a 
    champ, and I suspect you will see one aboard Gamma pretty soon, as 
    well.

    To all: Not sonar related but...
 
  It is said that 
    necessity is the mother of invention...
 
  The only dive I 
    have ever been on aboard a small submarine was hotter than hell. Nothing 
    against this sub captain or his submarine as I feel all small submarine 
    experience this problem when working in warm water and in the Summer 
    months.
 
  Solution?...
 
  A small 
    container installed aboard this submarine thru the already available access 
    hatch and set upright and out of the way. It appears as a small cooler with 
    an easy to open upper lid. 
  Prior to diving, this lid is opened 
    and a small bag of ice or perhaps several is simply poured into this 
    opening. It lands on a screen about 3/4 of the way down into this opening. 
    This lid is then closed and a small toggle switch is then turned 
    on.
  A 12 volt dc fan draws air from an intake port above this ice 
    and is supplied by a funnel such as is used on household  clothes 
    dryers from perhaps somewhere aft in the submarine. This air passes thru 
    this ice and into the this fan which exhaust it again into a tube sent 
    forward perhaps to several exhaust ports.
  As this ice melts, the 
    condensate drips down and is collected into a pan at the units base. This 
    pan is designed to slide out once full for disposal of this collected water 
    of perhaps 2 gallons. A high water level alarm could be installed as an 
    extra.
  At the dives end, this collected water is simply slid out 
    and thrown over the side as fresh ice is again installed into the units 
    upper lid assembly in preparation for the next dive.
  Of but the 
    power used to circulate air, no addition power is used to operate this 
    device so it is not much of an additional drain on the boats electrical 
    systems as would an actual ac unit.
  Although not perfect, this 
    device should lower the temperature enough to make diving a bit more 
    comfortable for both the submarine operator and that of his 
    passengers.
 
  Does this device seem worth while to 
    develop?
