Abstract:
1. A heat dissipation device cooling a power adapter, comprising: a first heat dissipation unit attached on a side of the power adapter; a second heat dissipation unit attached on an opposite side of the power adapter; at least one heat pipe thermally and mechanically connecting the first and second heat dissipation units; positioning elements securing the first and second heat dissipation units on the power adapter; wherein the positioning elements are extended through the first heat dissipation unit and secured to the second heat dissipation unit and first heat dissipation unit and wherein the power adapter is tightly sandwiched between the first heat dissipation unit and the second heat dissipation unit by the positioning elements wherein the first heat dissipation unit comprises first and second heat-dissipation portions and the at least one heat pipe is partly sandwiched between the first heat-dissipation portion and the second heat-dissipation portion.
