We report a novel coolant recirculation loop for high-power laser diodes which allows operating diode bar heat exchangers at their design coolant Reynolds number while consuming as little as 20% of their nominal coolant supply inflow. While operating in a single-phase regime, the new concept uses low coolant flow-rates comparable to proposed evaporative coolers. Unlike evaporative coolers, the new concept is compatible with many standard microchannel or impingement-type heat exchanger designs. The theory, design, and applications are presented.
