Yup, phase changing. Water in vacuum has to touch the heat source, evaporate, travel to the cooler side, condense and start over. As soon as your heat source prevents the cooling from happening, the cycle stops and it over heats. Like there’s a point at which the water can’t cool the source because its overwhelming.
I’m pretty sure the way heat pipes move heat is with water funny enough
