Product Overview
Aluminum cooling fin profiles from Ruhai integrate dense parallel fins into device housings and enclosure walls, turning the case itself into the heatsink.
One-piece extrusion means no thermal interface between fins and enclosure — better heat transfer than bolted-on heatsinks at lower assembly cost. Blue, black or natural anodized finishes for electronics styling.
Key Features
- Case-is-heatsink design — fins extruded into the enclosure wall
- High fin density — fin pitch down to 2.5 mm
- One-piece thermal path — no joints, no thermal paste
- Color anodizing — blue / black / natural for product styling
- CNC finishing — pockets, threads and flatness machining
Application Scenarios
Cooling fin extrusions cool sealed electronics:
- Inverters & drives — sealed enclosures with finned walls
- LED power supplies — passive IP67 cooling
- Communication devices — finned aluminum housings
- Medical & test instruments — silent fanless cooling
Configuration Options
- Alloy — 6063-T5
- Fin pitch — 2.5 mm minimum
- Enclosure width — 50-400 mm by die
