Integrated High-Density Extruded Aluminum Heat Sink With Mounting Brackets

All-in-One Cooling Profile for Industrial Power & Audio Equipment

This integrated high-density fin aluminum heat sink features extended mounting brackets on both sides, manufactured via one-piece aluminum extrusion. It combines heat dissipation function and installation structure into a single component, eliminating the need for separate mounting frames and simplifying equipment assembly.

Made of premium 6063-T5 aluminum alloy, the seamless integrated structure of solid base, dense parallel cooling fins and side fixing lugs delivers ultra-low thermal resistance and excellent structural rigidity. Pre-drilled holes on mounting brackets enable direct cabinet installation. We provide full customization including cut-to-length, CNC machining and multiple surface anodizing treatments for industrial power supplies, amplifiers and motor drives.

1. All-in-One Integrated Design Saves Assembly Cost Cooling fins and mounting brackets are extruded as one continuous aluminum piece. No extra brackets or fasteners are required to fix the heat sink to equipment cabinets, reducing your total part count and assembly labor time.

2. High-Density Fin Array Delivers Powerful Heat Dissipation Closely spaced vertical fins maximize heat exchange surface area within limited space. It works efficiently under both natural convection and forced air cooling conditions, effectively controlling temperature for high-power modules up to kilowatt level.

3. Dual Side Mounting Lugs for Flexible Installation Extended fixing lugs with standard through holes are designed for horizontal or vertical installation inside cabinets, chassis and equipment housings. The integrated bracket structure maintains stable positioning without bending under long-term operation.

4. Solid Flat Base Reduces Contact Thermal Resistance Thick solid bottom base provides full contact surface for power components such as IGBTs, MOSFETs and PCB power modules. Uniform heat spreading avoids localized hotspots and extends service life of electronic parts.

5. Highly Customizable to Match Your Equipment Layout We can cut the extrusion profile to any required length, and conduct secondary CNC machining to add mounting threads, wiring slots or positioning bosses according to your PCB and cabinet drawings. Multiple anodizing options are available to meet anti-corrosion and aesthetic demands.

· Industrial power electronics: frequency converters, servo drives, solar inverters, high-power switching power supplies

· Audio equipment: professional power amplifiers, vehicle audio power modules

· Telecommunication hardware: base station power units, RF signal amplifiers

· Automation control devices: industrial computer hosts, motor controllers, DC voltage regulators

1. One-Piece Aluminum Extrusion Molding High-grade 6063 aluminum billets are heated and extruded through dedicated precision dies to form the complete integrated profile with cooling fins and dual mounting lugs, ensuring uniform fin thickness and flat base surface.

2. Precision Cutting & Deburring Long extruded bars are cut to customer-specified lengths with high-precision saw equipment, followed by full deburring to remove sharp edges and prevent scratch damage during assembly.

3. Optional CNC Precision Machining Additional features including mounting holes, threaded inserts, wire outlet slots and positioning grooves are processed by multi-axis CNC machines with tight dimensional tolerances.

4. Surface Treatment Finishing Mill finish, clear or black anodizing can be applied to form a protective film on aluminum surface, improving corrosion resistance for indoor and mild outdoor industrial environments.

5. Strict Quality Inspection & Export Packaging All finished heat sinks pass dimensional measurement and surface defect inspection before shipment. Shock-proof foam and export cartons are adopted to avoid deformation during long-distance global transportation.
