Liquid cooled cold plates

Liquid cooled cold plates

With today's power devices becoming smaller and more powerful, liquid cooling is coming to the forefront as the best thermal solution. KINTO produces liquid-cooled cold plates with technologies of high precision CNC machining, extrusion and friction stir welding (FSW). The FSW technology provides solid state joint with mechanical properties similar to the parent materials, which results in a monolithic structure to achieve very strong hermetic seal. The high performance heat sinks offer efficient way to manage electronic systems with highly concentrated power and heat.

Cold plates can be manufactured out of aluminum, copper or laminated copper & aluminum, with surface treatment such as nickel plating or anodizing.

The tests include X-Ray checking of welding quality, tightness test (leakage test), flow resistance test, thermal resistance test, temperature-rise test under different power, heat sink efficiency test and simulation test of heat sinks for different application conditions.

Kinto's cold plate features:

- fine machined heat sink body and surface with high accuracy

- low pressure drops

- dual-sided cooling capability

- possibility of large heat sink size

- compatibility with industry accepted coolants

- friction stir welded (FSW) joints for excellent non-leakage and high pressure rating performance as well as high resistance to corrosion

Applications:

- high-power electronics

- lasers equipment

- power drives

- medical equipment

- military and aerospace industries
