Bonded Fin Heat Sinks

Running big electronics with lots of heat can push cooling past its limits and slow down your work. Our Bonded Fin Heat Sinks, built from aluminum or copper with extra fins, handle heavy heat loads to keep your systems going strong. 

Base Material

Aluminum (e.g., 6061) or copper base with matching or mixed fins; alloys customizable upon request

Thermal Resistance

0.2°C/W to 1.5°C/W, optimized for bonded fin-to-base contact efficiency

Heat Dissipation Capacity

100 W to 2500 W, ideal for large-scale, high-power electronic systems

Dimensions

Width: 50 mm to 500 mm; Height: 30 mm to 200 mm; Depth: 50 mm to 400 mm (customizable to fit specific designs)

Weight

0.5 kg to 12 kg, varying with base material, fin count, and size

Product Description

High power over big areas often makes heat that weak cooling can’t take away fast enough. Our bonded fin heat sinks fix this with many fins stuck tight to a base, giving your large setups the air and cooling they need. 

Fin Design

Bonded fins (straight or angled); fin pitch: 1 mm to 6 mm for high surface area dissipation

Mounting Type

Screw-mount, clamp-on, or base-integrated holes; suited for heavy-duty installation

Cooling Method

Passive (air-cooled) or active (fan-assisted), depending on system requirements

Operating Temperature Range

-40°C to 150°C, with maximum allowable base temperature rise of 60°C above ambient

Airflow Compatibility

Supports 20 CFM to 250 CFM, highly effective with forced airflow due to large fin area

Surface Finish

Anodized (aluminum) or nickel-plated (copper) for corrosion resistance and heat radiation

Noise Contribution

Silent (passive) or <45 dB (active cooling), low acoustic impact despite larger size

Durability

Rated for 60,000+ hours of operation under high thermal and mechanical stress

Environmental Resistance

Resistant to dust (IP55) and humidity (up to 95% RH non-condensing); vibration per IEC 60068-2-6

Standards Compliance

Meets RoHS and UL 94V-0 standards for environmental and flame-retardant safety

Thermal Interface Compatibility

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

Technical Advantages

Our bonded fin heat sinks move heat from 100 W to 2500 W, good for big power jobs. With fins 1 mm to 6 mm apart, they use lots of air to pull heat away fast. 

Working from -40°C to 150°C, they stay solid in hot or cold spots. That wide range keeps your big systems safe, stopping heat from hurting parts.

Industry Applications

Factory Machines

Cools motor controls, managing heat in big industrial gear. 

Solar Inverters

Takes heat from power converters, keeping energy flowing steady. 

UPS Units

Handles heat in backup power boxes, built for heavy electric loads. 

Train Systems

Keeps electronics cool in rail power units, fitting wide setups. 

Wind Turbines

Pulls heat from generators, made for large outdoor parts. 

Big Amplifiers

Protects audio gear, handling heat in wide speaker bases. 

Heavy Duty Heat Management

Large, hot-running jobs need cooling that can keep up without fail. Our bonded fin heat sinks, with heat resistance of 0.2°C/W to 1.5°C/W, lock in place with screw-mount or clamp-on picks. 

Too much heat in wide setups can break things or slow production. At 0.5 kg to 12 kg and following RoHS rules, our heat sinks bring big cooling power to keep your work on track.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How do bonded fin heat sinks take care of heat in our big power setups?

Our bonded fin heat sinks pull heat from 100 W to 2500 W, made strong for large electric jobs. That big power helps sourcing teams keep their wide systems cool and running good. 

What makes your bonded fin heat sinks right for our heavy air needs?

Bonded fin heat sinks work with air from 20 CFM to 250 CFM, using many fins to move heat fast. This fit keeps procurement heads happy with cooling that matches their big air systems. 

How do your heat sinks stay good in our wide, hot machines?

Our bonded fin heat sinks work from -40°C to 150°C, holding up in hot or cold places. That strength lets purchasing managers count on them for big machines that don’t stop. 

What space choices do bonded fin heat sinks give for our large builds?

We make them from 50 mm to 500 mm wide, built to fit any big design you have. That range helps sourcing teams pick cooling that works perfect for their wide setups. 

How do your bonded fin heat sinks keep our big products working long?

Rated for 60,000+ hours, our bonded fin heat sinks stay tough against heat and shaking (IEC 60068-2-6). That long run cuts fixes for procurement teams, making products last for years.
