Abstract: This paper describes the modeling, design, and testing of a high flux and yet compact two-phase CPU cooler, with excellent attributes of low thermal resistance that are derived from the intrinsic design features of phase change phenomena and minimal vapor pressure drop of the device. For the same footprint of a conventional cooler, the prototype rejects more than twice the capacity of CPUs of today. The unique design minimizes its overall size and yet provides adequate area for forced convection cooling. Testing was conducted over an assorted heat loads and air flow rates flowing through the fins, achieving a best performance of 0.206 K/W of device thermal resistance at a rating of 203 W under an air flow rate of 0.98 m3/min. The prototype device is orientation free where a 90° tilt could perform at the same rating conditions. © 2009 Elsevier Ltd. All rights reserved.
