HEAT DISSIPATION DEVICE
First Claim
1. A heat dissipation device, comprising:
- a heat sink defining a through hole therein; and
a heat pipe having an outer diameter slightly larger than a diameter of the through hole of the heat sink and being fixedly engaging in the through hole via interference fit, the heat pipe comprising a tube defining an interspace therein, a first wick formed on an inner surface of the tube, working fluid received in the interspace of the tube, and a retaining structure received in the interspace of the tube and abutting the first wick on the tube to enhance a rigidity of the tube, and a second wick being formed on an outer surface of the retaining structure.

Abstract
A heat dissipation device includes a heat pipe and a heat sink. The heat sink defines a through hole with a diameter slightly smaller then an outer diameter of the heat pipe. The heat pipe is fixedly engaging in the through hole of the heat sink via interference fit. The heat pipe includes a tube defining an interspace therein, a first wick formed on an inner surface of the tube, working fluid received in the interspace of the tube, and a retaining structure. The retaining structure is received in the interspace of the tube and abuts the first wick of the tube to enhance a rigidity of the tube. A second wick is formed on an outer surface of the retaining structure and connects with the first wick of the tube.
