Abstract
A heat spreader is disclosed. The heat spreader includes a body member, a first fin connected to the body member, a second fin connected to the body member, a third fin connected to the body member, and a fourth fin connected to the body member. The first and second fins define a first spacing therebetween. The second and third fins define a second spacing therebetween. The third and fourth fins define a third spacing therebetween. The second spacing is greater than the first spacing and the third spacing.
