Bonded Heat Sink

Bonded heat sinks are constructed by bonding a heat-conducting base, typically made of aluminum or copper, to a series of fins or heat-dissipating elements. This bonding process ensures optimal thermal conductivity, allowing heat to be efficiently transferred away from sensitive components and dissipated into the surrounding environment.

Our diverse base plate sizes allow us to tailor heat sinks to your specific size, shape, and performance needs. Automatic cutting ensures precise dimensions, while our friction welding technology lets us join multiple plates for extended lengths, meeting even the most demanding requirements.

Skived fin heat sinks are a powerful solution for efficient heat dissipation in air-cooled environments. Here’s how they work:

Precision Cutting: Thin metal fins are meticulously carved from a solid block at an optimal angle. This creates a dense network of fins that maximize surface area for heat exchange.
Consistent Performance: The repetitive cutting process ensures uniform fin spacing and structure, leading to reliable and predictable cooling performance.
Enhanced Efficiency: Compared to stitched fin heat sinks, skived fins offer an 8-15% improvement in cooling capacity, keeping your high-power devices operating optimally.

Ideal for demanding applications:

Skived fin heat sinks are perfect for a wide range of applications requiring superior heat dissipation in air-cooled environments, such as:

Electronics: Power supplies, servers, and high-performance computing systems.
Power Conversion: UPS systems, inverters, and motor drives.
Renewable Energy: Wind power converters and solar inverters.

STEP 1: Prepare aluminum baseplate and cooling fins according to the design drawings and create slots on the baseplate.

STEP 2: Bond the cooling fins to the baseplate by epoxy so as to join them into an assembly

STEP 3: Carry out machining and surface treatment on the baseplate and cooling fins so as to form the stitched fin heat sink.
