Coolant isn’t a high pressure system that sees the same stresses as a combustion engine. It doesn’t even have a change interval, though I will change that at some point too. There is gear oil that I would prefer to replace at 50k and likely will.
The benefit is the long life of the components and the lack of regular fluid changes combined with cheap power.
Actually, systems that don’t see the heat and pressure have greater needs of cleanliness and care, because if the water chemistry isn’t right and inhibited properly, biological growth is possible. That’s far worse. Ask anyone that works real power converter systems or large liquid cooled batteries.
Cheap components really aren’t, and obsolescence issues abound with power converters and solid state devices. These things are still in their infancy.
