They call a heatpipe smart because it is made with a very tiny pipe, etching really. It is this very small stuff that allows it to work better.

The "wick" used for the heat pipe is made of finely etched lines that are about as deep as fingerprints. The liquid is able to defy gravity--much like a kerosene lamp wick--as it flows between several locations and an arbitrary end point.
"That is the uniqueness--the ultra-fine etching," said Kevin Krewell, a senior editor at the Microprocessor Report. "Most of the heat pipes are tubes about the width of a piece of spaghetti or thicker."
