Standoff for cold plate and cold plate made with the standoff

摘要

A standoff for a cold plate and a cold plate using the standoff are characterized by a coil pack consisting of a plurality of individual fluid conveying tubes formed into a coil pack having a desired configuration and held in place by a plurality of retaining wires. The standoffs are slidably attached to the retaining wires and each comprises an elongate body that is triangular in cross-section, has a bottom end, an apex end opposite from the bottom end and a longitudinal bore toward the bottom end and through which a retaining wire extends. The standoffs are made of aluminum and are of sufficient size to maintain their structural integrity during a casting process in which the coil pack is placed in a mold and molten aluminum is poured around the coil pack. The standoffs support the coil pack above a lower surface of the mold and have a height between their base ends and apexes selected to create a desired thickness of cast aluminum material between the coil pack and an exterior surfaces of the finished cold plate.
