A heat dissipating device () for removing heat from electronic devices is disclosed. The heat dissipating device includes a heat sink () and at least one heat pipe (). The heat sink includes a Y-shaped heat conductive body and a plurality of fins () extending from the body. The body includes a solid block () and two extension arms () extending aslant from a top of the block in opposite directions. An U-shaped groove () is defined in the block and extends to an upper portion () of the block. The heat pipe comprises an evaporating portion () and a condensing portion () extending upwardly from the evaporating portion. The heat pipe is received in the groove so that the heat pipe absorbs heat via the evaporating portion and transfers the heat to the upper portion of the block via the condensing portion thereof.

Heat dissipating device

A heat sink clip ( ) is formed from a single piece of resilient metal by stamping. The heat sink clip includes an operation portion ( ), a pressing body ( ), a first and second arms ( ) extending from the opposite ends of the pressing body. The first and second arms each defines an aperture ( ) for engaging with a catch ( ) on a socket ( ) on which an electronic device ( ) is mounted. The pressing body presses a heat sink ( ) onto the electronic device. The operation portion extends from an end of the pressing body for readily engaging/disengaging the clip.

Heat sink clip

A clip assembly (,) includes a nail member (,), a sleeve member (,), and a spring (,) around the sleeve member. The nail member includes a cap (,), a post (,), a neck (,) and a cone-shaped barb (,). A pair of wedges (,) is formed on an outer surface of the post. The sleeve member is cylindrical. The sleeve member defines a central bore (,) for receiving the nail member, and a pair of rectangular slots (,) for receiving the wedges. A circumferential shoulder (,) is formed on the sleeve member, for abutting against a bottom surface of a heat sink. A lower portion (,) of the sleeve member defines cutouts (,), thereby also forming deformable fingers (,). The sleeve member is interposed between the heat sink and a PCB. The nail member is inserted down through the lower portion, and elastically expands the fingers of the sleeve member.
