Liquid Cooled Cold Plates

Liquids have much higher thermal conductivity than gases, and thus a much higher heat transfer coefficient; liquid cooling is far more effective than gas cooling. Liquid cooling has become a popular designer’s choice for the ever-increasing thermal load cooling requirements of today's industrial applications: i.e., laser, power conversions devices, transportation, and other high power density applications.

SNS Cooling offers the following liquid cooled technology products:

Direct contact cooling / surface contact cooling technology

Gun-drilled cold plate technology

Vacuum-brazed cold plate technology (copper / aluminum)

Direct contact cooling / surface booling cold plates are in direct contact with the device to be cooled, and thus have minimized resistance to heat transfer. Aluminum-filled epoxy is used to fill any small air gaps - the maximum thickness of the epoxy layer is 0.002" - to further reduce the overall thermal resistance of the cold plate. Copper, cupro-nickel, stainless steel, or aluminum tubes can be pressed into the pre-cut grooves for these cold plates.

SNS offers wide range of standard cold plates, as well as custom cold plates to meet specific cooling requirements, and SNS offers a leak-proof design for both inlets / outlets.
