1. A cooling device comprising:

  • a manifold comprising a fluid inlet surface, a fluid outlet surface defining an outlet manifold, and a fluid outlet, wherein;

    the fluid outlet surface is opposite the fluid inlet surface;

    the fluid inlet surface comprises an inlet channel fluidly coupled to a first jet region and a second jet region;

    the first jet region and the second jet region each comprise a plurality of jet orifices and a plurality of surface features extending from the fluid inlet surface;

    an individual surface feature of the plurality of surface features is positioned adjacent an individual jet orifice of the plurality of jet orifices;

    the first jet region and the second jet region are symmetrical about a line disposed in a center of the inlet channel; and

    the fluid outlet is fluidly coupled to the outlet manifold;

    a target plate coupled to the fluid outlet surface of the manifold, the target plate comprising a target surface, a first heat sink at the target surface, and a second heat sink at the target surface, wherein the first heat sink is aligned with the first jet region of the manifold, and the second heat sink is aligned with the second jet region; and

    a cover plate coupled to the fluid inlet surface of the manifold, the cover plate comprising a fluid inlet port fluidly coupled to the inlet channel of the manifold, and a fluid outlet port fluidly coupled to the fluid outlet of the manifold.
