    Idea for cooling. Think this would work?

    And just when I thought my tinkering days were over......

    Been thinking of ways to get the heat out of the kitchen and came up with a concept, so feedback is more than welcome.

    Idea is to have a one-way valve inlet/exit allowing heat to escape while protecting the interior from flooding. So I did a test with a mesh called Flow-Rite. It's very fine and resists water to a certain degree, yet air will pass through with a little force.
    In the test, I used 15oz of weight from water and inverted the container with the Flow-Rite attached. Water would not come out if it was in a level to semi level position whereby covering the mesh, however if I were to hold the cup sideways, the weight of the water would begin to pass through. (more testing needed)


    So then I thought of a one-way valve system (front and back) that when the EDF would run, the intake would open through vacuum as well as the exhaust.
    A float switch and relay would break the connection if the boat were to invert, thus automatically closing the one-way valves and shutting down the fan.

    A modified cowl could contain all the necessary parts. Small Lipo could be set into the hull.
    I may be wrong by thinking a three channel transmitter/receiver would be used to activate the fan setup, but a better idea might be a small circuit that activates the system when the boat motor itself is running. A timer chip could be set to have the cooling system run for a few seconds longer after the boat is not operated (upright).

    Looks good on paper, just wonder if there are any other thoughts on this?

    Thinking those are some new ideas to me. I like the mesh myself it would have to be protected from a high speed dunking or direct hit. Just having a top over it with an air gap just might do it. With that said I have had to try and keep things dry for years so I am not ready to take any chances of water killing my stuff. Ha Keep thinking you might be the guy to find the answer.

      Theoretically, if you put a hole in the hull, and make the hull airtight, water shouldn't come in the hole, based on the fact that, water can't come in if there is nowhere for the trapped air to go. Kind of like the old finger on the end of a drinking straw. The liquid doesn't come out of the straw till you release your finger. Just a thought.

          It's OK at one temp but hot and cooling off it will suck air and whatever back in.

              Are you inferring that a dramatic temp change 'high or low by a few degrees' will affect the mechanics/electronics in a negative way?
              I could understand that if they are critical to such, however if there was at least some stability, or average in the current temp, that should keep things happy I would think. And just that,.....thinking about it. Lol
              I'm going to continue with the experiment(s) as I think it's an issue that needs to be addressed with hot electrics.
              Btw, nice looking boat.

                Still working on some ideas to get enough volume of air passing through. The attached images are just a crude experiment and give an idea.
                I'm trying ways that use the least amount of material in consideration of weight/size.
                A slimmer unit could be achieved by using lead weights instead of my body filler (as that is what's at hand currently for weighting) This would help shorten the length while maintaining pressure on the plunger when closed.
                What I'm trying to achieve is a water tight seal when inverted without using electromagnetic switching (which would be optimum for locking up the plunger.)
                I still need to test how much external pressure it will take to open the system and taking into consideration the additional 'pull' in rough waters (bumps).
                Ideas welcome.
