Manufacturing technology and application of cold plate
2022-08-30

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.

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.

Cold plate

The manufacturing process of cold plate is a complex combined pipeline type in which the copper pipe is bent and embedded in the bottom plate, the bottom plate is machined and welded. According to the different welding methods, the machining channel of the bottom plate can be divided into vacuum brazing, friction stir welding, and other processes. Fins in the flow channel can also be divided into many types according to the process, such as profile, welding, etc.

High power devices are widely applied in many industries, such as SVG, frequency converter, inverter, IGBT, APF, etc. these devices can use cold plates for heat dissipation, and the heat dissipation effect is very good.
