One picture clearly shows a cooling jacket, and the renders look like liquid could flow into the stator the same way the wires do.
Having an outrunner configuration for this motor makes very little sense. It's hard to cool and power, and magnets are generally powerful enough to produce excess flux in the iron. Their field weakening would also work better with an inrunner since you could do it entirely electronically, and it would be easier to manufacture.
