What is Liquid Cold Plates (Liquid Cooling Plates)?

High-end applications, such as electronic components used in high temperature environments, require an efficient cooling system that does not interfere with operation.

Liquid Cold plates (also known as Liquid Cooling Plates) are used , as the most efficient cooling method, in vacuum chambers of vapor deposition equipment in the display manufacturing process and  protect electronic components from temperature environments of hundreds of degrees Celsius and thus provide a high level of performance and reliability to the equipment accordingly.

The cold plate with a water-cooled jacket structure heated in the vacuum chamber comes into contact with the cooling water circulating inside through a tube or passage (groove), which results in the entire cold plate being cooled, reducing the heat load by dissipating excess heat.

Cold plate of Kyoyu -SEISAKUSHO

Kyoyu Seisakusho’s cold plate has a water-cooled jacket structure made of aluminum, stainless steel and copper.
The method of joining the plate body and the water-cooled lid in the water-cooled jacket is specialised in Tig welding for stainless steel and friction stirring welding (FSW) for copper and aluminum. In addition, with advanced distortion technology, the ground contact with the heat source realises the optimal flatness and contributes to the improvement of cooling efficiency.
