Invention Idea – Rotating Cylinder In A Cold/Hot Fluid For Heat Transfer

Inspired by cooling a rotating soda can in icy water. To get a cold temperature fast. I wonder if heat transfer in for instance a heat pipe can be improved. If heat is suppose to go to the fluid then rotating the inner cylinder might make the process much faster and ?efficient.

I wonder if this could work for solar heat collectors also. Spinning an inside cylinder instead of having everything stationary.
