A cold plate, comprises: a housing having a surface providing a thermal interface for cooling an electronic device; a channel within the housing proximate to the surface for a liquid coolant to flow therethough such that heat received by the thermal interface is transferred to the liquid coolant; and a coolant port extending outside the housing, for transferring liquid coolant to and/or from the channel. A cross-sectional area of an outlet from the coolant port to the channel may be no larger than that of the channel at the outlet. Pins and/or fins may be arranged within the channel adjacent to the coolant port. The coolant port may cause liquid coolant to enter and/or exit the channel in a direction perpendicular to the surface. The coolant port may comprise an independent rotating fluid connector thereby allowing adjustment in the direction of a pipe coupled to the coolant port.
