KINTO Liquid-Cooled Heat Sinks

Product catalog summary

About Us
Kinto Electric Co. Ltd. is a Chinese manufacturer with four plants specializing in liquid cooled heat sinks, copper connection parts, insulation parts, and mechanical assembly parts. The company is ISO90001 certified and has 15 years of expertise, serving global clients like ABB and Siemens.

Product Features
Kinto's heat sinks are produced using advanced CNC machining and Friction Stir Welding (FSW) technology. Key features include high accuracy machining, low pressure drops, dual-sided cooling, large size capability, and compatibility with industry-standard coolants. FSW joints ensure non-leakage, high pressure rating, and corrosion resistance.

Design and Simulation
During prototype development, Kinto uses ICEPAK software for design and performance simulation, optimizing heat sink designs through computational fluid dynamics. This process includes heat transfer and fluid flow analysis before prototype testing.

CNC Machining
Advanced CNC machines like the Matec-30HV and Hammond CNC are used for precise machining of large parts and deep-hole processing, ensuring high precision and reliability.

Friction Stir Welding (FSW) Technology
FSW is a solid-state joining process that avoids melting the base material, resulting in joints with homogenous structures and mechanical properties similar to the parent materials. This technology is used for sealing heat sinks, offering advantages like no residual stress or deformation.

Material and Surface Treatment
Heat sinks are made from aluminum alloy or copper, with surface treatments like anodizing or nickel-coating to enhance durability.

Testing
Kinto employs advanced testing equipment for X-ray welding quality checks, pressure-withstand and tightness tests, and performance testing, including flow resistance, thermal resistance, and efficiency tests.

Applications
Liquid cooling is essential for high-power electronics, lasers, power drives, medical equipment, and military and aerospace industries. Kinto provides high-performance, reliable, and competitively priced liquid-cooled heat sinks and cold plates.

Product Examples
The document includes examples of various heat sinks, including copper and aluminum options, some with nickel-coating or anodized surfaces, and dual-sided cooling capabilities.

Sealing of Heat Sinks - Friction Stir Welding (FSW) Technology Friction Stir Welding (FSW) Technology Kinto is a partner of the licensed process in China. The unique possibilities of FSW enable us to produce liquid cooled heat sinks with outstanding performance. Friction Stir Welding (FSW): equipment for working piece max length 2300mm, max width 1400mm and welding thickness 1~16mm. FSW is a solid-state joining process in which the welding is done with frictional heat generated between the welding tool and the materials of the work pieces. The heat causes the stirred materials to soften without...
