Heat sink having non-straight fins for orienting a flow of an immersive cooling fluid

A system for collecting thermal energy from a plurality of heat generating components by circulating heat transfer fluid, wherein the system comprising a first heat sink and a second heat sink, wherein the first heat sink comprises:

• a base comprising:
• a thermal transfer surface configured to be placed in thermal contact with a first heat-generating component of the plurality of heat generating components, and
• an external surface opposite from the thermal transfer surface;
• and
• a first plurality of fins extending from the external surface, wherein at least two adjacent fins of the first plurality of fins define a curved fin passage therebetween along the external surface, wherein the second heat sink comprises a second plurality of fins forming a plurality of fin passages, and wherein the curved fin passage of the first heat sink directs the heat transfer fluid to the plurality of fin passages of the second heat sink.
