Two-phase cooling shows promise for data center applications due to the inherent high heat transfer coefficients- heat capacities- and iso-thermality associated with two-phase cooling. Thermal engineers are now considering the use of direct-to-chip liquid cooling solutions where the cold plates may be used in orientations that are atypical. This may include vertically orientated blades- two-sided CPU cooling- or servers oriented upside down (opposite to standard horizontal server orientation). In this paper- we present results for two-phase cold plates in these other orientations- without any modification to the original cold plate design. Ultimately- the two-phase cold plate performance was proven to be sufficient in all orientations without any modification to the original cold plate.
