Abstract:
1. A heatsink assembly structure, combined with a heat-generating element, wherein the heat-generating element is disposed on a circuit board and produces heat, the heatsink assembly structure comprising: a heat conducting board, attached to the heat-generating element and conducting the heat to the heat conducting board, wherein the heat conducting board comprises a fixing end fixed to the circuit board, and a plurality of through holes symmetric about the heat-generating element is formed in the heat conducting board in pairs; a plurality of pressing members, fixed to the heat conducting board and disposed between the heat conducting board and the circuit board, wherein the pressing members are fixed at positions between the through holes in pairs; and a plurality of spring plates, with two ends respectively penetrating through the through holes in pairs, and fixed to the pressing members between the through holes, such that when the spring plates are fixed to the circuit board with central portions of the spring plates, the spring plates generate pulling forces towards the circuit board at positions of the pressing members, so as to push the heat conducting board against the heat-generating element.
