Power consumption and thermal performance of integrated spray and jet array cooling vapor chambers

An integrated arrayed spray impingement vapor chamber (ISVC) is designed for cooling high-power electronic devices. The spray array is arranged on the vapor chamber to measure thermal performance in comparison with the other two integrated arrayed jet impingement vapor chambers (IJVCs) with differen...

The spray array is arranged on the vapor chamber to measure thermal performance in comparison with the other two integrated arrayed jet impingement vapor chambers (IJVCs) with different jet orifice diameters, named IJVC-0.8 and IJVC-3.0, on the basis of the inlet and outlet diameters of the spray nozzles.
