Hrm. I though it referred to distribution of energy, not temperature. “heat death of the universe” is when entropy can increase no more, and there are no differentials across space by which to define anything at conscious scale. No activity is possible when everything is uniform.

At least, that’s my simplistic summary - https://en.wikipedia.org/wiki/Heat_death_of_the_universe gives a lot more details, including the fact that my summary was probably not all that good even in the 19th century.
