Igbt Cooling Heatsink Silver Cooling Block

A vacuum brazed cold plate is a type of liquid-cooled heat exchanger used to manage heat in high-power electronic devices, particularly where efficient thermal management is crucial, such as in power electronics, lasers, batteries, and electric vehicles. Vacuum brazing is a manufacturing process where components are joined together in a vacuum furnace using a filler metal, resulting in highly efficient thermal and mechanical bonds.

Benefits of Vacuum Brazed Cold Plates:

1. Excellent Thermal Conductivity:

• Direct metal-to-metal bonding minimizes thermal resistance, allowing for efficient heat transfer between the cold plate and the heat source.

• This makes vacuum brazed cold plates particularly effective for high-performance cooling applications.

2. Leak-Proof Construction:

• The vacuum brazing process ensures a hermetically sealed, leak-proof structure with high integrity, which is crucial in liquid cooling applications where fluid containment is essential.

3. Complex Channel Design:

• Vacuum brazing allows for complex internal channels to be designed within the cold plate, optimizing the flow path for coolant and ensuring uniform cooling across the surface of the device.

• This can be tailored to specific cooling requirements, improving performance and efficiency.

4. Strong Mechanical Bonding:

• The brazing process creates a strong, reliable joint between the different components of the cold plate, ensuring structural durability and robustness under various operating conditions.

5. Corrosion Resistance:

• The materials commonly used in vacuum brazed cold plates (like aluminum and copper) are highly corrosion-resistant, especially when combined with the non-reactive environment in which the brazing occurs.

• This prolongs the lifespan of the cold plate, especially in harsh environments.

6. Uniform Heat Distribution:

• The cold plate's construction promotes even distribution of heat across the plate, preventing hotspots and ensuring that sensitive components stay within safe operating temperatures.

7. Lightweight and Compact:

• Vacuum brazed cold plates can be made from lightweight materials like aluminum, making them suitable for applications requiring both compactness and high efficiency, such as in aerospace or automotive sectors.

8. Customization and Flexibility:

• The vacuum brazing process allows for custom designs tailored to specific applications, whether in terms of size, shape, or internal flow path complexity.

9. High Reliability in High-Pressure Environments:

• Vacuum brazed cold plates can withstand high operating pressures without deforming or leaking, making them suitable for demanding environments where mechanical stresses or extreme temperatures are present.

10. Minimal Post-Processing:

• The vacuum brazing process typically results in minimal oxidation or contamination, reducing the need for additional cleaning or post-processing steps.

Common Applications:

• Power electronics cooling

• Electric vehicle battery and motor cooling

• Laser cooling systems

• Telecommunications equipment

• Renewable energy systems
