Extruded aluminum heat sink with CNC
machined mounting and assembly features.
This heat sink is manufactured from an aluminum extrusion profile and incorporates
CNC machined mounting holes and assembly features.
1 Design Considerations
Industrial power supplies generate heat from power semiconductors, transformers, power modules, and other electronic components during operation.
Heat sink geometry, mounting features, and manufacturing methods are typically configured according to thermal and installation requirements.
1.1 Fin Structure
The heat sink incorporates multiple cooling fins to increase the available heat dissipation area.
Fin dimensions and spacing are configured according to thermal requirements and profile design requirements.
1.2 Base Section
The base section provides the mounting surface for power devices and transfers heat to the cooling fins.
Base dimensions are configured according to thermal load and installation requirements.
1.3 Mounting Features
Mounting holes and machined surfaces are incorporated according to assembly requirements.
Additional machining operations may be performed to create installation and fastening features.
1.4 Surface Finish
Surface finishing may be applied according to environmental and appearance requirements.
Anodizing, hard anodizing, and powder coating are commonly used for aluminum heat sinks.
02 Aluminum Extrusion Profile
The heat sink profile combines a flat base section with integrated cooling fins in a single extrusion.
The profile incorporates the structural features required for subsequent machining and assembly operations.

03 Thermal Structure
Cooling fins are incorporated on both sides of the heat sink profile to increase the available heat dissipation area.
Fin quantity, fin height, and fin spacing are configured according to thermal requirements and profile dimensions.
The fin structure extends along the full profile length.

04 CNC Machining and Surface Finishing
After extrusion, CNC machining was performed to create mounting holes, threaded holes, and assembly features.
Machining details were configured according to the installation requirements of the power supply assembly.
Surface finishing can be applied according to corrosion resistance, appearance, and environmental requirements.
Common finishing options include anodizing, hard anodizing, and powder coating.

05 Finished Heat Sink Component
The finished heat sink incorporates cooling fins, mounting surfaces, and machined features required for industrial power supply applications.
Profile dimensions and machining features can be configured according to thermal and installation requirements.

06 Applications
Industrial power supply heat sinks are commonly used in power supplies, power converters, battery charging equipment, and industrial control systems.
Profile dimensions, fin structures, and machining features may be configured according to application requirements.
