A computational study of two phase jet impingement cooling of an electronic chip

Abstract

A two phase model has been developed and demonstrated for jet impingement cooling of a silicon chip. The Eulerian two-fluid model is applied for resolution of boiling heat transfer of a phase-change coolant. The simulation result predicts the overall cooling performance and is in reasonably good agreement with the reported experimental data. The boiling effect is found to be more pronounced for natural convection cooling than for the jet impingement scheme. A saturation point of the boiling effect is also observed in the jet impingement case. An optimized flow rate has also been found for the impingement jet cooling of the chip considered.
