ABSTRACT:
A portable electronic device includes a housing receiving a heat generating electrical component therein, a display unit and a heat dissipating hinge pivotably interconnecting the housing and the display unit. The heat dissipating hinge includes a body, a cover, a first heat pipe and a second heat pipe. A body defines a first receiving groove receiving a condenser section of the second heat pipe therein. The cover and the body cooperatively define a receiving channel receiving the evaporator section of the first heat pipe therein. Heat generated by the electric device is transferred from the heat generating electronic component to the display unit through the heat dissipating hinge. First and second supporting members are secured to two ends of the evaporator section of the first heat pipe to prevent leakage of thermal grease from a middle portion of the receiving channel.
