Abstract
A heat dissipating apparatus includes a centrifugal fan, a heat sink and a heat pipe. The centrifugal fan includes a frame and an air outlet defined on the frame. The heat sink is arranged adjacent to the air outlet of the centrifugal fan. The heat pipe includes an evaporation section and a condensation section extending from the evaporation section. The condensation section is connected to the heat sink. The evaporation section is for absorbing heat from a first and second heat generating component. The frame includes an elastic plate abutting to the evaporation section of the heat pipe and applying a force to the evaporation section of the heat pipe. An electronic device equipped with the heat dissipating apparatus is also provided.
Claims15
