Abstract: A fastening assembly used for securing a heat dissipation device to a printed circuit board, comprises a sleeve, an inserting device extending through the sleeve, a spring encircling the inserting device and received in the sleeve, and a supporting device inserted in the sleeve. The inserting device engages with a back plate below the printed circuit board. The sleeve is integrally formed of plastic and comprises a hollow body, a resilient portion extending from an outer surface of the body and pressing a bottom of the heat dissipation device upwardly, and four supporting portions extending from the outer surface of the body and pressing a top of the heat dissipation device downwardly. The supporting device is inserted between the body and the resilient portion, and abuts against the resilient portion, to thereby reliably keep the resilient portion at its locked position.

Abstract: An exemplary electronic device assembly includes a printed circuit board with an electronic component thereon, and a heat dissipation device. The heat dissipation device includes a heat sink mounted on the printed circuit board and a heat pipe pivotably engaged with the heat sink. The heat sink includes a main body defining a transverse channel therethrough and an injection aperture at a top of the main body to communicate the channel and an exterior of the main body. The heat pipe is pivotably engaging in the channel of the main body. A gap is defined between the heat pipe and the heat sink. Heat conductive grease is injected into the channel and filled in the gap between the heat pipe and the heat sink to thermally connect the heat sink with the heat pipe.
