Abstract
Abstract A cooling device includes a radiator. Each of two frames includes a central wall, first and second side walls protecting from the central wall, two claws formed on the central wall, a tab formed at a connection between the central wall and each of the side walls, two separated barbs formed on the first side wall, two cutouts defined in the second side wall. Each of two bolts includes two terminal portions and a central portion biased from the terminal portions. Each of handles protects perpendicularly from one of the terminal portions of a corresponding one of the bolts. An integrated circuit to be cooled by the cooling device is received in a socket including four corners. The radiator is located on the integrated circuit. The frames are assembled about the socket by engagement of the barbs with the cutouts while the tabs are located below four corners of the socket. Each of the bolts is inserted through the first hole defined in one of the frames and the second hole defined in the remaining one of the frames. The handles are pivotable for rotating the bolts thus abutting the radiator against the integrated circuit by the central portions of the bolts. The handles can be retained by the claws.
