Patent attributes
A heat dissipation device is provided for dissipating heat generated by electronic components mounted on a printed circuit board in an electronic system. The electronic components have different heights. The heat dissipation device includes a connecting plate, at least two elastic members mounted on the connecting plate, and a heat sink having a substrate mounted on the connecting plate and located above one of the electronic components. A number of joining members extend through the printed circuit board and engage with the substrate to attach the substrate on the one electronic component on the printed circuit board. A distance between the substrate and the connecting plate is adjustable by adjusting the joining members to make the substrate intimately contact the one electronic component.
