Abstract
A heat sink includes a first flange, a second flange, and an accordion-shaped medial portion continuous between the first flange and the second flange. The first flange and the second flange are configured to be attached to a circuit board. The accordion-shaped medial portion includes troughs on a proximal side of the accordion-shaped medial portion and crests on a distal side of the accordion-shaped medial portion such that the heat sink is configured to disperse heat away from the circuit board.
Claims15
A heat sink comprising:
- a first flange;
- a second flange;
- an accordion-shaped medial portion continuous between the first flange and the second flange;
- and
- a spring pin,
- wherein:
- the first flange and the second flange are configured to be attached directly onto a top surface of a circuit board;
- the accordion-shaped medial portion includes troughs on a proximal side of the accordion-shaped medial portion and crests on a distal side of the accordion-shaped medial portion such that the heat sink is configured to disperse heat away from the circuit board;
- the accordion-shaped medial portion includes planar sections between the troughs and the crests;
- at least one of the planar sections has a height which is different than a height of each of a remainder of the planar sections such that the heat sink is shaped for accommodating components of various sizes on the circuit board;
- and
- the spring pin is configured to attach the first flange or the second flange directly to the circuit board.
