Fin-type Heat Sink
In high-power industrial and electronic applications, thermal management is the critical factor determining product performance and lifespan. For high-power LEDs, approximately 70-80% of electrical energy is converted into heat. If not dissipated effectively, excessive junction temperatures can lead to light decay, color shifting, and catastrophic failure. Rich Sphere Precision (RSP) offers advanced High-Power Elevated Fin-Type Heat Sink solutions featuring a patented "non-welded" process that sets new standards for lightweight, eco-friendly, and high-efficiency cooling.
RSP’s elevated fin-type heat sinks are engineered for extreme precision and high thermal conductivity.

The patented non-welded riveting procedure used by RSP solves the most common pain points in traditional heat sink manufacturing.
Aluminum Savings: Compared to traditional aluminum extrusion, this technology saves over 40% of aluminum material.
Lightweight Design: The significant reduction in mass is ideal for high-power elevated lighting such as street lights and high-bay fixtures that have strict structural load requirements.
Bonded Stitched Fin Technology: This process involves bonding small, wedge-shaped fins together.
High Aspect Ratio: In a compact footprint, this technology creates a fin density and aspect ratio far superior to traditional extrusion, dramatically increasing the surface area for heat exchange.
Seamless Connection: The riveting process ensures a high-pressure mechanical fit between the fins and the baseplate.
Efficiency: This unified structure minimizes thermal resistance at the interface, with data showing heat elimination performance that overtakes traditional aluminum extrusion.
This table details the differences between RSP’s patented process and traditional manufacturing methods.
| Comparison Dimension | RSP Patented Non-Welded Riveting | Traditional Soldering (Reflow) | Traditional Extrusion |
| Environmental Impact | Lowest (No plating, zero pollution) | High (VOCs/chemical treatment) | Medium |
| Material Waste | Minimal (40% Al savings) | Medium | High |
| Thermal Efficiency | Excellent (High density/low resistance) | High (Limited by solder resistance) | Baseline |
| Tooling Costs | Low (Flexible for grooved bases) | High (Solder/Reflow oven costs) | Medium (Expensive molds) |
| High-Temp Stability | High (No risk of solder aging) | Medium (Long-term joint brittleness) | High |
RSP’s elevated fin-type technology is widely deployed in high-heat industrial sectors:
High-Power LED Lighting: Street lights, floodlights, high-bay kits, and AR111/PAR lamps.
Telecommunications: High-end OSFP and QSFP-DD transceiver thermal modules.
Electronics: GPU cooling, power amplifier PCBs, and server CPU heatsinks.
