ABSTRACT:
A cooling device includes a fin unit with an upper side to which a fan unit is mounted and an underside to which a central processing unit is mounted. The fin unit includes a base plate and a plurality of fins projecting upwardly from an upper side of the base plate and extending parallel to a perimeter of the base plate thereby forming a frame-like structure with a second perimeter and defining a space therein. Four ledges are defined between the perimeter of the base plate and the perimeter of the fins. At least one hook member is formed on each of two opposed ledges and a slot is formed in the ledge adjacent to each hook member. A plurality of second fins project upwardly from the upper side of the base plate in the space defined by the first-mentioned fins, each second fin having a height less than that of the first fin for mounting the fan unit in the space above the second fins. A fastener member has a first end for engaging with the hook member and a second hook end passing through the slot to securely retain the central processing unit to an underside of the base plate. The second perimeter defined by the first fins has four corners, a seat with a hole being provided in each corner for mounting the fan unit.
