As I understand it, it’s more than that: there are small “inverted pyramids” that cause the water to condense more rapidly, to extract even more heat from the system.

texture etc to promote condensation and to wick (without a rope) condensed liquid back to the hot point are also used in heat pipes.

I agree with the other commenters that "vapor chamber" is a kind of heat pipe, since "heat pipe" doesn't really impose constant radii by definition.
