Abstract
Jet-impingement, two-phase cooling apparatuses and power electronics modules having a target surface with single- and two-phase surface enhancement features are disclosed. In one embodiment, a cooling apparatus includes a jet plate surface and a target layer. The jet plate surface includes a jet orifice having a jet orifice geometry, wherein the jet orifice is configured to generate an impingement jet of a coolant fluid. The target layer has a target surface, single-phase surface enhancement features, and two-phase surface enhancement features. The target surface is configured to receive the impingement jet, and the single-phase surface enhancement features and the two-phase enhancement features are arranged on the target surface according to the jet orifice geometry. The single-phase surface enhancement features are positioned on the target surface at regions associated with high fluid velocity, and the two-phase surface enhancement features are positioned on the target surface at regions associated with low fluid velocity.
