GWHT Beijing Introduces HeatRuler for Cooling High Powered LEDs

GWHT Beijing, a high tech company for researching and developing products, is proude to introduce a new technology for high power LEDs thermal management. The innovative LED heat sinks with HeatRuler inside can effectively solve the thermal management problem of high powered LED lighting.

Specifications:
•   Material: pure aluminum
•   Capillary structure: micro-grooves or fins
•   Superficial heat conductivity: 1,000,000 Watts/mK
•   Isothermal: <1 K/m
•   Max. themal flux: 100-200 W/cm²
•   Operating temperature: -120°C to 180°C
•   Interior stress strength: 60 kg/cm²
•   Exterior stress strength: 40-60 kg/cm²
•   Sizes: thickness 0.8-5.0 mm; length 10-5,000 mm; width 5-100 mm

HeatRuler- Micro heat pipe array (MHPA):
MHPA patented, registered and sold as "HeatRuler", invented by Pro Zhao yaohua, is the best heat exchange and transport material on the market for energy systems, as well as for heat dissipation and control in high-heat -flux, high power, and confined-space heat generating components.

HeatRuler is a flat metal plate with multiple parallel micro-heat-pipes operating independently inside. The MHPA's performance is superior to a single micro-heat-pipe, as it has far a greater cumulative surface area that contributes to the evaporation and condensation cycle.

Heat sinks:
LED heat sink with heatruler inside is the ideal products for cooling high powered LEDs. It can bring the temperature of the led base plate down to below 55°C, raise the efficiency of the led up by 30%, increase the lifespan up to its theoretical term of 100,000 hours, and greatly reduce the unit’s weight and cost. Now there are several kinds of heat sink for up to 1000w LEDs. For example, one new type of heat sink for 400 watts has 180 heatrulers inside with the weight of 2.5kg and the size of 300*200*200mm.
