Vehicles, power electronics modules and cooling apparatuses with single-phase and two-phase surface enhancement features

A power electronics module comprising:

• a jet channel;
• a jet plate surface comprising a jet orifice having a jet orifice geometry, wherein the jet orifice is in fluid communication with the jet channel and is configured to generate an impingement jet of a coolant fluid;
• a target layer comprising a target surface, single-phase surface enhancement features, and two-phase surface enhancement features, wherein:
• the target surface is configured to receive the impingement jet at an impingement region;
• the single-phase surface enhancement features are positioned on the target surface at high fluid velocity regions;
• and
• the two-phase surface enhancement features are positioned on the target surface at low fluid velocity regions;
• and
• a semiconductor device thermally coupled to the heat transfer surface.
