[NSRCA-discussion] Heat Sinks

[Jay Marshall]

Well, the skin of my cells is AL as it is so this sounds reasonable. I would
coat the AL with thermal compound.

I've been thinking about this, and I think the best way would be sandwich
thin pieces of aluminum between the cells and extend past the edge of the
pack. But I'm not sure I like the idea of placing anything electrically
conductive between the cells. Best to provide an air space between the cells
and duct the cooling air between them.

 

Of course, if you really want some wow-factor in the setup, you would have a
thermostatically controlled cowl flap that only opens up once the pack
starts to go beyond the optimum temperature. Maybe even an emergency cooling
system - a small CO2 cartridge from an air rifle might do. ;-)

The idea of a real heat sink, maybe with the fins as part of the skin of the
plane and in the airstream, and the LiPo cell edges bonded to the sink with
thermal compound, has some merit and may require some investigation - if
cooling is what we really want.
