Patent ID: 7085136

Claim:
A heat duct-equipped heat-radiating device for power supply, comprising: (a) a heat conductive board having a boar body section fixedly connected in a housing of the power supply and tightly attached to a heat source of the power supply; (b) a heat duct tightly bridged over the board body section of the heat conductive board, one end of the heat duct protruding outwardly from the housing of the power supply, the heat duct having a duct body tightly attached to and bridged over a connecting seat, the connecting seat being correspondingly locked on the heat conductive board; and (c) a fin body composed of multiple fins, the fin body being fixedly mounted on outer side of the housing of the power supply, the fins of the fin body being respectively formed with corresponding fitting holes through which the heat duct is fitted to contact with the fins, whereby the heat generated by the heat source of the power supply is quickly conducted through the heat duct to the fin body on outer side of the housing and dissipated from the fin body to outer side.
