Abstract:
1. A heat sink fixing device, comprising: an enclosing frame socket having a central part for disposing a heat generating unit thereon, with a heat sink being mounted on the enclosing frame socket and covering the heat generating unit; a first fixing part provided on a bottom surface of the heat sink; and a second fixing part provided on the enclosing frame socket and corresponding to the first fixing part, allowing the first fixing part of the heat sink to be coupled to the second fixing part of the frame socket so as to connect the heat sink to the enclosing frame socket, thereby substantially maximizing heat dissipating area on the heat sink, wherein two suspending arms and two first fastening parts are respectively formed on two opposing sides of the enclosing frame socket, wherein one end of each of the suspending arms is pivotally coupled to the enclosing frame socket and linked to a fixing member, and the other end of each of the suspending arms has a second fastening part corresponding to the respective one of the first fastening parts, so that when the second fastening part of each of the suspending arms is fastened to the corresponding one of the first fastening parts, the fixing members linked to the suspending arms are actuated, causing the first fixing part of the heat sink to be firmly coupled to the second fixing part of the enclosing frame socket.
