Abstract
A heat dissipation device includes a fixing bracket and a heat sink connected to the fixing bracket in a horizontal rotation manner. The fixing bracket includes a fixing plate defining a through hole. Two blocks extend up from a top of the fixing plate around the through hole. A latching portion extends towards the through hole from a top of an inner side of each block. The heat sink includes a bottom plate, a number of fins extending up from a top of the bottom plate, and a base extending down from a bottom of the bottom plate. The base is received in the through hole of the fixing bracket and includes a main body, and two flanges extending outwards from a bottom circumference of the main body, to engage with bottoms of the latching portions, respectively.
