Description
Jet impingement is an efficient cooling method that sprays coolant directly onto the heat source. This removes the heat transfer impact of the support structure materials – including TIM – by allowing heat to pass unimpeded into the coolant. In data center and turbine blade cooling applications, jet impingement has been demonstrated to remove heat fluxes more than 300W/cm2. There is lack of literature using CO2 jet impingement, especially in the two-phase regime, which benefits from natural disruption of the vapor layer and low pressure drops. This work develops an experimental setup for simulation validation and cooling performance characterization. The setup uses a 3D printed titanium cooling manifold which can be swapped out to explore various geometries. First results from this setup in the single- and two-phase regimes will be presented. This work aims to provide engineers predictive correlations with which to design future cooling devices.
