High Performance Next Generation Liquid Cold Plate

Wakefield Thermal vacuum-brazed liquid cold plates are created by machining two metal plates with interior channels and fin structures (zipper fin), which are then carefully sealed together inside a vacuum chamber. A filler metal with a lower melting point is melted into the joints of the cold plate via capillary action. The vacuum created in the chamber removes the atmosphere, thus preventing the forming of oxides that would normally form during the brazing process. Without the vacuum, a flux would be required to protect the joints as they are formed. The vacuum-brazing process creates an exceptionally strong joint and does not require any brazing flux. The vacuum-brazed cold plate has unparalleled flexibility in its design, as it is not limited by the bending radius limitations of Wakefield Thermal standard tube and plate cold plates.
