LED Heat Sink with Fan (Cooling Module)

I. Structural Composition

• Heat sink body: Aluminum extrusion/finned heat sink with anodized surface to expand heat dissipation area
• Cooling fan: DC silent fan (12V/24V), exhausting air outward or blowing air inward for forced convection
• Thermal interface layer: Thermal grease/thermal pad, connecting LED chips and aluminum PCB
• Mounting accessories: Screws and buckles, compatible with flood lights, high‑bay lights, stage lights and grow lights

II. Core Features

• Active cooling with fast temperature reduction and low thermal resistance; supports high‑power LEDs from 50W to over 300W
• Compared with pure aluminum heat sinks, it features smaller size, longer chip service life and less light attenuation under the same power
• Temperature‑controlled models support automatic start/stop or speed regulation according to temperature, with lower noise and power consumption
• Drawbacks: Fan noise, power supply required, and dust‑proof maintenance needed for long‑term use

III. Common Application Scenarios

IV. Selection Guidelines

• Power matching: Specifications of heat sink and fan shall be no less than the actual power of the LED
• Voltage: Fans commonly use 12V or 24V, matching the LED driver voltage
• Noise: Choose silent fans for household/indoor use, and high‑air‑volume fans for industrial use
• Protection level: Select waterproof fans and waterproof aluminum housings for outdoor applications
