Cooling apparatuses having a jet orifice surface with alternating vapor guide channels

摘要

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.
