Re: [Electric Boats] Re: 12V Accessories (Refrigeration)

Hello all,    I don't believe it necessary to go to such lengths as modifying the hull. not sure if photos go on-page here but this is of a Corsair h60 water cooled heat sink. Far more effective than the stock aluminum heat sinks as OEM. Got mine re-furbished for $39US. The coleman 40qt peltier cooler ($88) is very robust and the uses a quality peltier module also contains a temp sensor on the outside heat sink.

Removing the outside aluminum heat sink with this off the shelf water cooled heat sink will provide a wider temp range for the peltier.   Placing the 'radiator' portion closest to the hull will provide for cooler air. Adding a temp sensor and gauge to the outside reduces the desire to opening the cabinet to ck on how cool things are. This unit is also capable of lying flat, keeping more cool air trapped inside while lifting the door and makes it much more easier to add Insulation wrapping on the container.
Always ienjoy reading of the engineering efficiencies of various components but in the meanwhile I have a unit easily operable, already available and allows for some tinkering pleasure. If you require freezing consider a smaller cooler and purchase a stacked TEC system for it.   Using both coolers provides a lot of flexibility.   Thanks all.   Nick
