High-Performance Round Aluminum Heat Sinks (Sunflower & Cylindrical)
Skip standard limitations. At Kingka, we manufacture high-efficiency round heat sinks tailored to your specific thermal loads and spatial constraints. Thanks to their radial fin design, round heat sinks provide excellent omnidirectional heat dissipation, making them the industry standard for cylindrical enclosures and natural convection environments.
Our Manufacturing Capabilities:
Unlike standard suppliers, we offer end-to-end custom manufacturing for round heat sinks:
Extrusion & Cold Forging: Whether you need cost-effective extruded "sunflower" profiles (AL6063) or ultra-dense cold-forged pin fins (AL1070) for high-power applications, we have the right process for your project.
Precision CNC Machining: Our in-house CNC centers can handle complex secondary operations, including drilling, tapping mounting holes, and facing the base for optimal thermal contact.
Custom Surface Finishes: As shown in our gallery, we provide premium surface treatments including clear/black/color anodizing, sandblasting, and chemical passivation for enhanced corrosion resistance and visual appeal.
Ideal Applications:
High-Power LED Lighting (High bay lights, downlights, grow lights)
Cylindrical Motor Housings & Servo Motors
Power Electronics and Audio Amplifiers
Telecom Base Station Components
