Heat exchanger with enhanced heat transfer manifold

A heat exchanger, comprising:

• a heat exchanger core;
• a first inlet manifold in fluid communication with the heat exchanger core, the first inlet manifold (FIM) having a FIM fluid inlet and a FIM fluid outlet;
• a first turbulence generating structure disposed adjacent to the FIM fluid inlet of the first inlet manifold, and a first separation distance from the FIM fluid outlet;
• and
• a second inlet manifold in fluid communication with the heat exchanger core, the second inlet manifold (SIM) having a SIM fluid inlet and a SIM fluid outlet;
• wherein the heat exchanger is configured with a first fluid flow path through which a first fluid flow enters the heat exchanger through the FIM fluid inlet, encounters the first turbulence generating structure and passes through the FIM fluid outlet, and into the heat exchanger core, wherein the first turbulence generating structure is configured to produce turbulence in the first fluid flow;
• wherein the first separation distance is long enough such that the first fluid flow entering the heat exchanger core is free of the turbulence resulting from the first turbulence generating structure;
• and
• wherein the first turbulence generating structure has a circular cross-section having a diameter, and the first separation distance is in the range of fifteen to twenty-five times the diameter of the first turbulence generating structure.
