Patent ID: 7007739

Claim:
A cooling system for use in a direct chilled casting mold system with a mold cavity, the mold system being configured for molding a metal castpart, the cooling system comprising: a cooling framework configured for location around a perimeter of a mold cavity, the cooling framework comprising: a first plurality of coolant discharge apertures configured at a first end to receive coolant at a first coolant flow rate, and configured at a second end to discharge a first discharge coolant flow at a first coolant discharge velocity toward a first fractional surface portion of a castpart being molded; a second plurality of coolant discharge apertures configured at a first end to receive coolant at a second coolant flow rate, and configured at a second end to discharge a second discharge coolant flow at a second coolant discharge velocity toward a second fractional surface portion of the castpart; wherein the first coolant flow rate is approximately equal to the second coolant flow rate; and further wherein the first coolant discharge velocity is less than the second coolant discharge velocity.
