Thermal Radiation FinsNeng Tyi knows what is the best to house high-power LEDs. The rivetingstructure created the lightest weight, and led to the highest efficiency.

Dented each heat fin to increase thermalconductivity. Inserted 30 ~ 48 pieces of thinthermal fins to optimize different applications.

Aluminum99.7% of purity

Anodizing aluminum to increase thermalconductivity, corrosion resistance and

durability, and create electrical insulation.

A conventionalapplication countsheavily on thermalradiation, which

dissipates generallythe least heat.

Mechanical structure is derivedfrom the cooler of SONY PS3.Thermal fins, composed pieceby piece, create more space for

Thermal-fins Manufacturing

Owned 18 punch-press machines ranging from 20 to 200 tons to produce allkinds aluminum riveting heat fins.

More than 6,000 mold templates for punch-press equipments prove Neng-Tyis capability to help you develop what you need.

The measurement of Neng Tyis computer numerical control machinery is

1 micrometer () precision.

Manufacturing Considerations

When manufactured, the thermal fin structure needs far lessenergy consumption than die-casting one.

The mass production rate for thermal fins

is better than that for die-casting. 150thermal fins can be formed in one minute.

In consideration of recycling, the thermal fin structure made fromnearly pure aluminum is a eco-friendly design.

ReliabilitiesIn accordancd with IEC 60598, Neng Tyi conducts DielectricWithstanding Voltage, Contact Resistance, InsulationResistance, Arc resistence, and Leakage Current testing.

Used HORIBA X-ray analytical microscope tocheck the purity of raw material of aluminum.

Sprayed 5% of NaOH (salt) solution at the anodizedaluminum radiation fins to verify the corrosion resistance.

LED lamps were placed in the chamber, with 140 of temperatureand 90% of humidity, for 24 hours. The testing result is going toindicate the oxidation resistance of products.
