Brazing Heat Sink for Motor

The Brazing Heat Sink for Motor is a high-performance cooling solution designed for efficient heat dissipation in motor applications. Utilizing advanced brazing technology, it forms a seamless metal-to-metal bond, eliminating thermal barriers and optimizing heat transfer. This heat sink supports multiple materials, including aluminum, copper, stainless steel, and titanium, ensuring versatility and reliability. Winshare Thermal’s precision brazing process guarantees a cost-effective, durable, and high-performance solution for both air and liquid cooling systems.

Key Features

  • Superior Heat Dissipation – Brazed metal-to-metal bonding minimizes thermal resistance, enhancing heat transfer efficiency.

  • Multi-Material Compatibility – Supports aluminum, copper, stainless steel, and titanium for diverse applications.

  • Reliable Manufacturing Process – Precision brazing ensures long-lasting durability and structural integrity.

  • Flexible Design Options – Adaptable for various air and liquid cooling system configurations.

  • Leak-Free Liquid Cooling – Fast-sealing technology prevents leaks and enhances performance.

Air Cooling Technology

  • No thermal barrier between the base and fins for enhanced cooling efficiency.

  • Fast and cost-effective manufacturing with flexible design options.

  • Reliable and stable performance over extended use.

Liquid Cooling Technology

  • High reliability with a completely sealed, leak-free brazed structure.

  • Rapid sealing process for superior durability.

  • Cost-effective solutions available for medium to high-performance applications.

Material Considerations

  • Recommended Alloys: 6060, 6063, and 6101 offer better performance than 6082.

  • Aluminum Properties: Extruded aluminum anneals during brazing but regains 80% of its original strength after cooling.

  • Mixed-Material Brazing: Aluminum, titanium, and stainless steel can be brazed together. Copper bases with aluminum fins require special techniques.

  • Size Limitations: Maximum brazing dimensions are 600 x 1200 mm, with 450 x 800 mm recommended for optimal performance.

Design Best Practices

Base Plate

  • Any thickness possible, but an extruded “U” shape with thick external fins is recommended for protection.

  • Minimal deformation during brazing, within standard extrusion tolerances.

  • CNC machining is easily applied after brazing.

Fins

  • Avoid overly tall and thin fins for better thermal and mechanical stability.

  • Pure aluminum provides optimal thermal conductivity and is ideal for automated production.

  • Stacked fins are the best choice for medium-to-high-volume manufacturing.

  • Fins can be of different heights or lengths if needed (may increase costs).

Additional Considerations

  • Design the base to support fan mounting without additional machining.

  • Short and thick fins maximize cooling efficiency.

  • Slots in fins are used to increase airflow turbulence; airflow exits only from the front and back.

  • For liquid cold plates (LCP), consider cover thickness for high-pressure applications.

  • Stainless steel tubing is recommended for mixed circuits or aggressive fluids.
