Abstract: A compound heat-dissipating device is used to help a chip or a CPU to dissipate excessive heat. The compound heat-dissipating device has two heat sinks, two fans respectively arranged on the two heat sinks, and a heat pipe connected between the two heat sinks for increasing efficiency of heat dissipation.

Abstract: A heat dissipation method is provided for an electronic apparatus including a housing, a circuit board mounted in the housing, and a heatsink device mounted between and rested on the housing and the circuit board. The heatsink device includes a heatsink plate having a bottom face rested on a surface of the housing, and a heat conductive plate having a bottom face rested on a top face of the heatsink plate and a top face rested on a bottom face of the circuit board. Thus, the heatsink device dissipates the heat produced by the heat sources of the circuit board largely and rapidly, thereby enhancing the heat dissipation effect of the electronic apparatus.
