1. A heat dissipation device, comprising:
a vapor chamber in contact with a heat source and having a chamber formed in the vapor chamber;
at least one heat pipe having a first end and a second end, wherein the first end and the second end are communicated with the vapor chamber;
at least one partition disposed in the at least one heat pipe and partitioning an inside of the at least one heat pipe into a first channel and a second channel isolated from each other; and
a heat dissipation fin set disposed on the vapor chamber and partially covering the at least one heat pipe,
wherein the chamber is filled with a liquid working medium, and the liquid working medium absorbs heat of the heat source and then gasifies into a gaseous working medium, and the gaseous working medium moves into the first channel and the second channel to be condensed by the heat dissipation fin set, such that the gaseous working medium is liquefied into the liquid working medium, and then the liquid working medium flows back into the chamber,
wherein space of the first channel at the first end is larger than space of the second channel at the first end, and space of the first channel at the second end is smaller than space of the second channel at the second end.
