1. A system comprising:

  • an enclosure enclosing electrical components and configured to prevent air within the enclosure and exhaust from the electrical components from escaping the enclosure;

    a heat sink at least partially within the enclosure, the heat sink comprising;

    a main housing within the enclosure, the main housing having a flat and thermally conductive main housing surface for laying against an electrical component shelf surface or for receiving electrical components directly thereon;

    thermally conductive fins positioned alongside each other, adjacent to the main housing, and within the enclosure; and

    a tube extending into and out of each of the main housing and the fins to transport liquid through both the main housing and the fins; and

    a fan enclosed by the enclosure, the fan configured to push air heated by electrical components onto the fins;

    wherein the fins are configured to receive a first heat from air pushed by the fan, and transfer the received first heat to the liquid being transported by the tube through the fins;

    wherein the main housing is configured to receive a second heat from the electrical components on the thermally conductive main housing surface and transfer the received second heat to the liquid being transported by the tube;

    wherein the main housing further comprises a first edge and a second edge opposite the first edge;

    wherein the fins further comprise a first edge and a second edge opposite the first edge, the main housing second edge being adjacent the fins first edge;

    wherein the tube enters the main housing at the main housing first edge;

    wherein the tube enters the fins at the fins first edge;

    wherein the tube exits the fins at the fins first edge; and

    wherein the tube exits the main housing at the main housing first edge.
