Abstract:
1. A heatsink module dissipating heat generated by a first heat-generating element and a second heat-generating element which are disposed on a circuit board, the heatsink module for dual heat sources comprising: a first heat-conducting plate, contacting a surface of the first heat-generating element, for conducting heat generated by the first heat-generating element to the first heat-conducting plate, and the first heat-conducting plate having a first claw portion; a second heat-conducting plate, contacting a surface of the second heat-generating element, for conducting heat generated by the second heat-generating element to the second heat-conducting plate; a fixing member, having a second claw portion, wherein the fixing member is fixed to the circuit board, and presses the second heat-conducting plate against the second heat-generating element, so as to conduct heat of the second heat-conducting plate to the fixing member; a heat pipe, with one end clamped by the first claw portion and the second claw portion, so as to conduct heat of the first heat-conducting plate and the fixing member to other end of the heat pipe; and a pressing flat spring, having a pressing portion, wherein one end of the pressing flat spring is fixed to the circuit board and other end is fixed to the fixing member, such that the pressing portion is pressed against the first heat-conducting plate, and the first heat-conducting plate is pressed against the first heat-generating element.
