Liquid Cold Plate

Liquid cooling liquid cold plates liquid cooling is a natural evolution beyond air cooling where either due to thermal requirements or footprint requirements the desired performance can no longer be economically met by air cooling.

Liquid cold plate.

Liquid cooled cold plates are commonly used for high heat flux or high power electronics cooling applications. Uniform cooling since the coolant flowing inside the plate absorbs heat of device the surface temperature varies near the inlet and the outlet. Columbia staver are experts in liquid cooling offering a range of cold plate e g. These cost effective liquid cold plates are designed specifically for low to medium power density applications.

The performance of liquid cold plates varies greatly depending on the flow path and the accuracy of the contact surface with the heat source even if the material and pump capacity are the same. Hydrotrak the d6 hydrotrak series of liquid cold plates use a patented design and manufacturing technique making it a high performance liquid cold plate. These standards cold plates come in 2 and 4 pass versions. Wakefield vette s rolled tube liquid cold plates are usually the most cost effective liquid cold plate solutions.

Custom pressed tube liquid cold plates are available with either continuous tube styles or a manifold style to increase tube density within the liquid cold plate. Component heat flows by conduction through a thermal interface material and the metal plate to the metal tubing. Liquid cold plates for high power and high heat flux applications. The performance of these components is critical to the overall effectiveness of the liquid system.

A cold plate is responsible for taking the heat from the device s and transfer it to a single phase liquid coolant circulating through internal channels of the plate and subsequently reject it downstream to a radiator. Serpentine tube in plate gun drilled multi piece designs friction stir welded vacuum or dip brazed. Cold plates provide localized cooling by transferring heat from a device to a liquid that flows to a remote heat exchanger and dissipates into either the ambient or to another liquid in a secondary cooling system. This product line utilizes a custom tube profile that improves surface area and heat conduction angles from the surface to fluid.

Manifolds are brazed to tubes and tested for 100 leak free performance. The key attribute for this line of standard cold plates is that the liquid flow is contained in a continuous tube. When air cooled heat sinks cannot cope with too high power densities liquid cooled cold plates are the heat transfer solution of choice.
