Abstract:
1. A heatsink assembly structure combined with a heat-generating element, wherein the heat-generating element generates heat and is disposed on a circuit board, the heatsink assembly structure comprising: a rectangular heat conducting plate, comprising a pressing surface and an abutment surface, wherein the abutment surface is attached on the heat-generating element to conduct the heat to the heat conducting plate; and two spring plates, each with elongated length-wise edges which are parallel to the elongated length-wise edges of the rectangular heat conducting plate, and each comprising at least one fixing section and a plurality of pressing sections extending from the fixing section, wherein the fixing section is fixed to the circuit board, such that each of the pressing sections applies a force to press the heat conducting plate towards the heat-generating element, wherein each spring plate further comprises a slot hole formed at the end of the spring plate; and at least one stop member, wherein the stop member is a rivet that is fixed in a respective slot hole and to the heat conducting plate, so as to limit a moving path of an end of a respective spring plate.
