SDU cooling options

[Riwi]

Hi!

Whats your solution for cooling the SDU?

1. Feed the inverter and motor (heat exchanger) in parallell, if so what flow and size of radiator.

2. Serial cooling, first inverter, second motor.

3. Two seperate loops for motor and inverter.

Whats your experience and recommendation?

Hi, I have been pondering the same thing for my SDU setup - what have you come up with so far?

What were your findings? Ready to pull vacuum and fill. Would be nice to know before filling my coolant in.

If you split the coolant loop between 2 items you run the risk of having more coolant flow through one or the other leaving the possibility of overheating for the low flow item.

You can get around this with a pump for each, some restrictor to lessen flow on one circuit to balance it, or entirely split cooling loops.

I'd suggest following the flow route the OEM used. They likely balanced in a lot more low cost into the equation than someone diy-ing it, but it should still work well that way.

OEM/Tesla split the routing to inverter and gearbox on the SDU.
