Hello,
i am planning my first USV for bathymetric surveys on lakes anywhere between 10 to 20ha at the moment and i think i figured everything out right now.
However, since i do not have any experience with this type of equipment yet, i am thinking about the heat radiation from the ESCs and if they would need any cooling.
Plan is, to build all the equipment into something like a pelicase or something similar, which by definition is watertight aswell as airtight. So it came into my mind, that temperature build up could possibly cause some problems.
The boat is designed to swim at slow speeds (somewhere around 1m/s) and the ESCs (2 of them) i’m thinking about will be 30A-40A without a fan.
So i guess, some simple airvents would not be sufficient enough.I have been thinking about a fan on top of the case with a cover ontop to hold off any splash water. Now i’m unsure if just one fan pumping air in is enough. Or would it need another air outlet? Do you maybe have some ideas to make this more or less waterproof again?
Does anyone have some field experience here, which he would be willing to share? Maybe temperature isn’t a problem after all?
Thanks for your input
P.s. here is my rudimentary 3d design. Just to provide a picture. The top part with all the electronics will be encased. Black would be the 2 batteries. Blue the esc. Red the pixhawk.
