Abstract
A heat dissipation structure includes a heat sink having a base formed with four securing tabs laterally extending from four corners of the base. Four positioning posts upwardly protrude from a printed circuit board. Four spring clips are attached to the four positioning posts respectively. Each of the four spring clips has a resilient piece for exerting a downward force to press a corresponding securing tab, thereby securing the heat sink to the printed circuit board.
Claims20
A heat dissipation structure, comprising:
- a heat sink comprising a base comprising four securing tabs, each of the four securing tabs laterally extending from each corner of the base;
- a printed circuit board comprising four positioning posts upwardly projecting from the printed circuit board;
- and
- four spring clips, each of the four spring clips being attached to each of the four positioning posts, wherein each of the four spring clips comprises a resilient piece, the resilient piece being configured to exert a downward force and to press each of the four securing tabs, thereby securing the heat sink to the printed circuit board.
A heat sink mounting apparatus for mounting a heat sink on a printed circuit board, the heat sink comprising a base formed comprising four securing tabs, each of the four securing tabs laterally extending from each corner of the base, the heat sink mounting apparatus comprising:
- four positioning posts secured to the printed circuit board and each of the four positioning posts being located in each corner of a rectangle;
- and
- four spring clips, each of the four spring clips being attached to each of the four positioning posts, wherein each of the four spring clips comprises a resilient piece defining a positioning hole, the positioning hole being configured to receive each of the four positioning posts;
- the resilient piece is configured to exert a downward force and to press each of the four securing tabs, thereby securing the heat sink to the printed circuit board.
