  • Patent number: 9460985
    Abstract: Jet-impingement, two-phase cooling apparatuses having alternating vapor outlet channels are disclosed. In one embodiment, a cooling apparatus includes a fluid inlet channel, a jet orifice surface, and a target surface. The jet orifice surface includes an array of jet orifices. The jet orifices are arranged in rows. Coolant fluid within the fluid inlet channel flows through the array of jet orifices as impingement jets. The jet orifice surface further includes a plurality of vapor guide channels positioned between the plurality of jet orifice rows and parallel to a first axis such that the jet orifice surface is defined by alternating jet orifice rows and vapor guide channels. The target surface has a plurality of surface fins extending from a surface of the target surface and parallel to a second axis that is orthogonal to the first axis, wherein the jet orifice surface is positioned proximate the surface fins.

  • Patent number: 9099295
    Abstract: Jet impingement and two-phase cooling apparatuses with sloped vapor outlet channels are disclosed. In one embodiment, a cooling apparatus includes a fluid inlet channel, a jet orifice surface having one or more jet orifices fluidly coupled to the fluid inlet channel such that coolant fluid within the fluid inlet channel flows through the one or more jet orifices as one or more impingement jets, and a target surface. The target surface and the jet orifice surface define an impingement chamber where the one or more impingement jets impinge the target surface at an impingement region such that at least some of the coolant fluid changes to a vapor. The cooling apparatus further includes a plurality of sloped vapor outlet channels that are fluidly coupled to the impingement chamber. Coolant fluid flows through the plurality of sloped vapor outlet channels after it impinges the target surface.
