How Do Cold Plates Work?

Today’s most demanding, high-performance electrical and technological applications were made possible largely due to innovative thermal management techniques. In applications where power output is high and space is limited, cold plates have become vital for their combination of high thermal conductivity and compact design. At Noren Products, we specialize in providing the most efficient solutions for transferring electrical waste heat, and that includes custom-designing cold plate applications for systems that cannot be efficiently cooled with ambient heat exchangers.

Liquid Cold Plates

Cold plates are typically made from metal, with flow paths machined into them for a heat-transfer fluid to flow through. As the plates absorb electrical waste heat, they dissipate it through the flow paths using liquid cooling. The flow paths inside the cold-plates can be machined in various  shapes and sizes, and can allow cold plates to more effectively absorb and transfer large amounts of heat. The effective heat transfer coefficient of a cold plate depends on the available surface area in the flow paths, the liquid used, the flow rate of the liquid, and the material used to make the cold plate.

Determining the best cold plate solution for any given application begins with a thorough analysis of the system and its requirements. Many of our clients are surprised to learn that we can not only improve on the designs they may have in mind, but also provide higher efficiency and cost-saving benefits than they expected.
