3 different fluids is nothing unexpected. Even a street car has three different fluids. (coolant, oil, atf for example)
Engine coolant
Engine Oil cooling circuit (likely also cooled by engine coolant)
Gearbox oil cooling circuit
Battery cooling circuit (electrics use a different coolant)
Hydraulics cooling circuit (not sure here what is used)
Charge air cooling circuit) different coolant
oil isn't a great coolant tho, you'd only use it to do something else as well as cooling, and if you're cooling it direct to air that doesn't count
that goes for hydraulic oil and transmission oil, they're not coolants primarily they get cooled.
this is the point really, or it was, that if you ONLY want to cool with it, you just use the fluid with the best characteristics don't you, of specific heat, viscosity or whatever, for transporting heat. So what else are you doing? Or you might have something lighter for a high-mounted radiator like ammonia or something. Batteries yes i suppose non-conducting might be good lol. Anyway it'd count as interesting for me, if we knew more about it
