Thermal Resistance

0.2°C/W to 1.2°C/W, ensuring high-efficiency heat transfer for critical electronics

Heat Dissipation Capacity

50 W to 1000 W, suitable for avionics, radar, and power modules in aerospace systems

Dimensions

Width: 50 mm to 300 mm; Height: 25 mm to 150 mm; Depth: 50 mm to 250 mm (customizable to fit specific designs)

Weight

0.2 kg to 5 kg, optimized for minimal weight in aerospace applications

Product Description

Vibration, temperature swings, and weight limits often threaten aerospace electronics, causing failures or redesign costs. Our heat sinks are engineered to tackle these issues, delivering robust heat dissipation (50 W to 1000 W) and lightweight designs with durable materials.

Fin Design

Extruded or pin fins; fin pitch: 2 mm to 5 mm for efficient heat dissipation in tight spaces

Mounting Type

Bolt-on or clamp-on; designed for secure attachment under high-vibration conditions

Cooling Method

Passive (air-cooled), leveraging high-altitude or forced airflow in aerospace environments

Operating Temperature Range

-55°C to 150°C, with maximum allowable base temperature rise of 60°C above ambient

Airflow Compatibility

Supports 20 CFM to 150 CFM, optimized for natural or forced airflow in flight or field

Surface Finish

Anodized or MIL-spec coated for corrosion resistance and thermal emissivity

Noise Contribution

Silent (passive cooling), avoiding acoustic interference in sensitive defense systems

Durability

Rated for 70,000+ hours of operation under extreme thermal and mechanical stress

Environmental Resistance

Resistant to dust (IP66), moisture (up to 95% RH), vibration, and shock per MIL-STD-810

Standards Compliance

Meets MIL-STD-810, DO-160, and RoHS standards for aerospace and defense reliability

Thermal Interface Compatibility

Pre-applied thermal paste or compatibility with aerospace-grade TIMs (e.g., graphite-based)

Technical Advantages

Aerospace electronics face constant exposure to vibration and extreme temperatures, risking component breakdown. Our heat sinks are constructed with aluminum (standard) or copper options and coated to MIL-spec standards, holding strong from -55°C to 150°C.

Effective heat control is vital for system stability and weight efficiency. Our heat sinks achieve thermal resistance as low as 0.2°C/W and weigh just 0.2 kg to 5 kg, providing powerful cooling without overloading your designs.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How do your heat sinks improve system uptime in aerospace applications?

Our heat sinks manage heat loads from 50 W to 1000 W with a thermal resistance as low as 0.2°C/W, keeping critical electronics stable under extreme conditions. This performance reduces the risk of thermal-related failures, offering procurement teams a solution that boosts system uptime and cuts maintenance demands for flight or field operations.

What options do we have to keep weight low in our aerospace designs?

We provide aluminum as the standard material, weighing just 0.2 kg to 5 kg, with copper or composites available for higher heat needs. This range lets sourcing professionals balance cooling power and weight limits, ensuring your designs meet strict aerospace requirements without excess mass.

How do these heat sinks handle the shock and vibration of defense environments?

Built with bolt-on or clamp-on mounting and tested to MIL-STD-810 standards, our heat sinks withstand vibration and shock in rugged conditions. This strength minimizes component loosening or failure, giving purchasing managers confidence in equipment that performs through missions or combat scenarios.

What testing processes back up the quality of these heat sinks for our production?

Our heat sinks undergo MIL-STD-810 and DO-160 testing for environmental and avionics reliability, covering temperature, vibration, and altitude extremes. This rigorous validation ensures sourcing teams receive parts that meet aerospace and defense specs, reducing quality risks and speeding up your certification process.

Can your heat sinks support both prototype builds and full-scale production runs?

Yes, they come in customizable dimensions (50 mm to 300 mm wide) and mounting options to fit prototype or production designs, from small avionics to large radar systems. This adaptability simplifies procurement by providing a consistent cooling solution across development stages, lowering costs and lead times for scaling up.
