Benefits
Water-cooled laminated busbars offer higher power admissibility, metal savings, hot spot suppression, and global heat decrease. They allow for custom cooling paths and increased current density, with the option to inject warm water in low-temperature environments.

Technical Insights
Laminated busbars consist of layers of copper or aluminum separated by dielectric materials, offering reduced system costs, improved reliability, increased capacitance, and elimination of wiring errors. They provide structural integrity and can integrate cooling solutions to manage high temperatures and space constraints in power electronics.

Performance Comparison
Graphs demonstrate significant temperature reduction with water cooling. For example, a 3 mm busbar's temperature is reduced by 23°C, and a 0.8 mm busbar's temperature is reduced by 58.5°C when cooled with 15°C water.
