Large Format High Density Extruded Aluminum Heat Sink

This large format high density fin extruded aluminum heat sink is a robust thermal solution engineered for high-power industrial and electronic equipment where maximum heat dissipation is critical. With a wide, solid base and densely packed parallel fins, this profile delivers exceptional surface area for both natural and forced convection cooling, making it ideal for power-hungry systems that demand reliable thermal stability.

 

 

Manufactured from premium 6063-T5 aluminum alloy via one-piece extrusion, this heat sink eliminates thermal interface resistance, ensuring fast, uniform heat transfer across the entire structure. We offer this standard profile in custom lengths, with optional CNC machining and surface treatments to meet your exact design and performance requirements.

 

 

 

 

High-density tooth design with ultra-large heat dissipation area

Its fins are extremely dense and numerous, forming a large heat dissipation surface on a broad base. This design is tailored for high-power equipment with high heat flux density, such as industrial power supplies, frequency converters, high-power amplifiers, and server power modules. The height and spacing of the fins are optimized to maximize cooling area while ensuring smooth airflow and preventing heat accumulation.

 

Integral extrusion molding process

It is a typical aluminum extruded radiator made of 6063-T5 aluminum alloy, featuring high thermal conductivity (approximately 205 W/m・K). The base and fins are integrally formed without any assembly gaps, resulting in extremely low thermal resistance. Heat is quickly and evenly conducted from the base to each fin, making it far more efficient in heat dissipation compared to welded or assembled radiators.

 

The spacious solid base

The solid bottom base is exceptionally thick, ensuring sufficient contact area with the heating element to reduce thermal resistance. Additionally, the sturdy base can store more heat, preventing sudden overheating of the device and enhancing thermal stability.
