A cold plate is formed without the conventional fins that form a sinuous path for chilled water in the cold plate cavity, and the cavity is filled with beads. Chilled water flows in the space between the beads. The beads produce a lower flow resistance than the conventional fins, and they produce turbulence in the water flow that greatly enhances the transfer of heat from the cold plate to the water. The beads may be of materials, such as glass, that have poor thermal conductivity. Preferably, the beads are thermally conductive, and their surfaces form part of the thermal path to the chilled water. The beads may be randomly packed or packed with a suitable symmetry. The beads may be fused or unfused.
