Abstract:
A cold plate for cooling electronic components comprising:a base having a top surface onto which at least one electronic component is to be placed; a cooling well formed in the top surface of the base and open at the top; a feed channel formed in the base for accepting a cooling fluid to be introduced to the cooling well; a drain channel formed in the base through which the cooling fluid is to be carried away from the cooling well; a cooling well inlet formed in the cooling well and in communication with the feed channel; and a cooling well outlet formed in the cooling well opposite the cooling well inlet and in communication with the drain channel; wherein the feed channel is sufficiently large relative to the size and flow characteristics of the well and cooling well inlets and outlets such that when the cooling fluid flows through the cooling device, the pressure drop across the feed channel is substantially less than the pressure drop across the well.
