Product Description

Heavy metal sinks or weak alternatives can throw off your design goals, adding weight or failing under thermal stress. Our composite heat sinks solve this with a lightweight build and solid performance, tailored for cutting-edge applications where every gram counts. 

Fin Design

Extruded or molded fins; fin pitch: 1.5 mm to 5 mm for effective heat dissipation

Mounting Type

Screw-mount, clamp-on, or adhesive; adaptable to complex or lightweight enclosures

Cooling Method

Passive (air-cooled) or active (fan-assisted), depending on composite properties and needs

Operating Temperature Range

-50°C to 140°C, with maximum allowable base temperature rise of 55°C above ambient

Airflow Compatibility

Supports 10 CFM to 180 CFM, effective with natural or forced airflow in diverse setups

Surface Finish

Coated (e.g., epoxy, thermal paint) or untreated composite surface for durability and heat radiation

Noise Contribution

Silent (passive) or <38 dB (active cooling), minimal acoustic impact in sensitive systems

Durability

Rated for 65,000+ hours of operation under thermal, mechanical, and environmental stress

Environmental Resistance

Resistant to dust (IP55), moisture (up to 95% RH), and vibration per IEC 60068-2-6

Standards Compliance

Meets RoHS, UL 94V-0, and MIL-STD-810 (where applicable) for environmental and safety standards

Thermal Interface Compatibility

Pre-applied thermal pads or compatibility with advanced TIMs (e.g., carbon-based, polymer-enhanced)

Technical Advantages

Our composite heat sinks manage heat from 30 W to 1200 W, offering versatile cooling for both small and demanding systems. With molded or extruded fins (1.5 mm to 5 mm pitch), they maximize airflow, reducing thermal buildup without extra weight. 

Coated finishes like epoxy or thermal paint fend off dust (IP55) and moisture (up to 95% RH). That protection keeps your electronics running smoothly, cutting maintenance in varied or harsh setups.
