Abstract
A heat dissipation device for dissipating heat generated by an electronic device on a printed circuit board includes a heat sink and a plurality of mounting devices. A plurality of retaining pillars are secured on the printed circuit board at positions around the electronic device. Each of the mounting devices includes a fixing portion connecting with the heat sink, a mounting portion extending from the fixing portion and a locating portion extending from the mounting portion to a position below the mounting portion. The retaining pillars on the printed circuit board extend through the locating portions and abut against bottoms of the mounting portions to accurately position the heat dissipation device on the electronic device on the circuit board before fasteners are brought to extend through the mounting portions to screw in the retaining pillars.
