Anyways thank you very much. How much time from where I was to this did it take you and what all (short answers) did you have to do?
I will now start trying to make the layout.

Something like this, which you could weld a plate on one end with two fittings, and a plate on the other with a notch out of the gussets so the coolant flows down then back up.

Absolutely not.
The 2 big reasons are the caps will be in the middle making all 6 power switches share current from and to all caps much better and
the Driver boards will be outside to help reduce noise.
Now having said that the heat will be easier to remove from the outside. Having the heat sink face outwards will make air cooling work much better.
Remember even liquid cooling is air cooled. With something like this you want to keep the heat sinks as cool as possible and every time you have to transfer heat from 1 surface to another you have differences. If we put a heat sink right on the back and a fan on it that's the best we can do without using co2 or HVAC.
Yes they are. It also lets me change the thickness to what I can actually source when I get home. I need to dress them up a bit yet but it all a learning experience for mecoleasterling said:Did you model the bus bars as sheet metal features in SW? If so, great job. That makes it a lot easier to unfold and send out for laser work.
