Vacuum-Brazed Copper Water-Cooled Plates for Power Electronics Cooling

As power density in modern electronic and electrical systems continues to rise, effective thermal management has become a critical design factor. From EV inverters and motor drives to industrial power supplies and high-frequency converters, components generate significant heat that must be controlled to ensure efficiency and long-term reliability.

Copper water-cooled plates are one of the most widely used solutions for removing this heat, thanks to copper’s excellent thermal conductivity and the ability to design internal channels for liquid cooling.

The Role of Copper Water-Cooled Plates

Copper water-cooled plates are commonly used in:

• Power electronics modules and IGBT cooling
• EV motor controllers and battery thermal systems
• Industrial drives and high-power rectifiers
• Renewable energy inverters (solar, wind)

These systems often operate continuously and under varying load conditions. A well-designed water-cooled plate ensures that sensitive components stay within safe temperature limits, improving both performance and life expectancy.

Why Vacuum Brazing is Ideal for Cooling Plate Production

To function effectively, these plates require:

• Precisely machined internal flow channels
• Strong, hermetically sealed joints
• Minimal internal contamination or oxidation

Vacuum brazing is the ideal process to achieve these requirements because it:

• Creates clean, flux-free joints inside the cooling passages
• Ensures uniform bond strength over large surface areas
• Minimizes distortion and maintains dimensional accuracy
• Provides leak-tight performance, essential for pressurized coolant systems

Normantherm’s vacuum brazing furnaces are specifically designed to support this type of precision joining.
