1. A power module, comprising:
a heat generating electrical component;
a passive heat dissipation element in contact with and facing a first surface of the heat generating electrical component, the passive heat dissipation element comprising:
one or more contact points, the one or more contact points including a curved surface; and
a planar surface facing the heat generating electrical component; and
a fin system comprising a plurality of fins attached to a base plate, the plurality of fins extending from the base plate and away from a second surface of the heat generating electrical component opposite the first surface, wherein each exterior surface of each of the plurality of fins includes a first exterior surface and a plurality of other exterior surfaces, the first exterior surface being attached to the base plate and the plurality of other exterior surfaces being floating surfaces, wherein the curved surface thermally connects the planar surface of the passive heat dissipation element to the fin system; and
a fin housing including walls, the walls including a first end connected to the base plate and a second end defining an opening in a surface of the fin housing, wherein the walls define a chamber between the first end at the base plate and the second end at the opening, and wherein the plurality of fins extend less than a length of the chamber from the first end at the base plate to the second end at the opening.
