Abstract
A heat sink device for a chip comprises a heat sink, a pair of mounting portions and a pair of fixing bolts. The heat sink includes a base, a plurality of fins and a pair of tabs symmetrically extending from opposite corners thereof and having a hole. Each mounting portion includes a main body, a resilient arm upwardly and inwardly extending from an end of the main body and a pair of clamping portions extending from the edges of the main body. Apertures defined in the main bodies and openings defined in the resilient arms correspond to the holes of the tabs. Each fixing bolt includes a cap, a beam, a latch and a step.
Claims13
A heat sink device for placing on a board-mounted electronic element, comprising:
- a heat sink including a base, a plurality of fins extending upward from the base, and a pair of tabs extending from opposite corners of the base, each tab defining a hole;
- a pair of mounting elements each being at least partially resilient forbeing adjustably mounted to a respective tab of the heat sink, each mounting element including an arcuate portion and an opening aligned with the hole of each tab;
- and
- a pair of fixing bolts each inserted through the opening of each mounting element, the hole of each tab and a hole of a printed circuit board, each fixing bolt including a cap for pressing against a top of the mounting element and a latchadapted for abutting against a bottom of the printed circuit board, thereby resiliently compressing each mounting element to exert a downward force to each tab of the heat sink.
A heat sink device comprising:
- a heat sink including a base with a plurality of fins upwardly extending therefrom, a pair of tabs extending from the base and each having a through hole;
- a pair of resilient mounting elements each attached to a corresponding tab, said mounting element having a hole in an upper portion thereof and a restraint means on a lower portion thereof;
- and
- a pair of fixing bolts each including an elongate beam with a cap at a top portion thereof and a latch at a bottom portion thererof;
- wherein
- said beam extends through the hole of each mounting element with the cap abutting against the upper portion of the mounting element and through the through hole of the heat sink with said restraint means retaining to the tab to assemble said mounting element to the tab.
