New High Performance Cold Plate Technology

Vacuum Brazed Cold Plate

Woburn, MA, June 22 2004. Lytron has introduced a new high performance, vacuum brazed, cold plate capability based on its aluminum extended surface technology. This cold plate consists of Lytron's extended surface cold plate material, a micro-channel aluminum extrusion, sandwiched between lightweight aluminum sheets.

The extended surface cooling channel ensures low liquid pressure drop and the all-aluminum construction makes it lightweight. It is joined together using vacuum brazing techniques, ensuring that it is highly reliable, leak-proof and not susceptible to corrosion. The performance of this cold plate is close to that of a conventional vacuum brazed cold plate, and for certain configurations it is significantly less expensive.

This technology offers extremely flexible customization options. The cold plate can be exactly matched to customer's thermal requirements by appropriate positioning of the cooling channels. This means that it can provide distributed cooling over the whole surface of the plate, or it can be configured for localized cooling. It can be supplied with flat surfaces, or it can be custom machined to match exactly with the electronics board or other object being cooled. Mounting studs and taps and through-holes can also be incorporated into the design.
