High Efficiency Air Cooled Heat Sink For High Power Equipment

1. Integrated extrusion dense tooth forming process

Adopting high-precision extrusion technology to create a uniform dense tooth structure, maximizing the expansion of heat dissipation area, heat conduction without splicing faults, low wind resistance and high air circulation efficiency, heat exchange can be quickly completed with the assistance of natural wind/fan.

Adaptation advantages: Suitable for medium to high power conventional scenarios such as industrial cabinets, photovoltaic inverters, and general electronic control equipment, achieving efficient heat dissipation in limited installation space, meeting the basic heat dissipation needs of 24-hour continuous operation of equipment, with high cost-effectiveness and wide adaptability.

2. CNC precision milling process for flat surfaces

Perform high-precision CNC milling and precision grinding on the thermal base and installation surface, with high smoothness and flatness error ≤ 0.02mm, seamlessly fitting with the equipment heat source, significantly reducing contact thermal resistance, and eliminating local heat accumulation at the heat source point.

Adaptation advantages: Suitable for precision electronic modules, power semiconductors, high-frequency inverters and other equipment that require high heat dissipation accuracy, accurately fitting core heating elements, solving precise heat dissipation problems in compact layouts, and adapting to the design needs of miniaturization and integration of equipment.

3. Surface anodizing/passivation protection process

The fins and base are treated with anodizing (aluminum)/passivation (stainless steel)/electroplating (copper) to form a dense protective layer, which enhances the anti-oxidation, dust-proof, and anti slight corrosion properties, improves surface hardness and wear resistance, and reduces the impact of dust and scaling on heat dissipation efficiency.

Adaptation advantages: Suitable for outdoor communication base stations, open industrial equipment in workshops, and power equipment in humid and dusty working conditions, with no heat dissipation performance degradation in complex environments, extending the service life of radiators, and reducing maintenance frequency in outdoor/harsh industrial scenarios.

4. Air duct optimization stamping process

When stamping fins, directional air ducts are designed with a streamlined tooth pitch to reduce air flow resistance, improve the exchange rate of hot and cold air, achieve efficient heat transfer at low wind speeds and low power consumption, and balance heat dissipation and energy-saving noise reduction.

Adaptation advantages: Adapt to scenarios with strict requirements for noise and energy consumption such as server rooms, data centers, indoor communication cabinets, etc., avoid noise pollution caused by high wind speed fans, and meet the operating standards of low noise and energy-saving equipment in the computer room.
