ABSTRACT:
A heatsink module for dual heat sources for dissipating heat generated by a first and a second heat-generating element disposed on a circuit board is provided. The heatsink module includes a first heat-conducting plate, a second heat-conducting plate, a fixing member, a heat pipe, and a pressing flat spring. The first and second heat-conducting plates contact the first and second heat-generating elements respectively. The fixing member when fixed to the circuit board presses the second heat-conducting plate against the second heat-generating element. One end of the pressing flat spring is under the traction of the fixing member fixed to the circuit board, and presses the first heat-conducting plate against the first heat-generating element. The fixing member and the first heat-conducting plate then clamp the heat pipe, so as to conduct the heat generated by the first and second heat-generating elements to the heat pipe via the connecting elements.
