200-500w heat sink
Product features
Strong cooling capability: heat flux removal can reach 400 W/cm2. Its cooling capability is 1000 times that of forced water cooling and 100 times that of heat pipe

Surface temperature uniformity is within ±2.

compared with the traditional heat sink the product is 50% lighter and 20% smaller.

No power consumption with  Passive cooling without fan or pump. .

simple, compact, stable and easy to start up. Reliability is much higher than that of fan cooler, forced water cooler system. .

suitable for SMD  CREE LEDS  OR COB LEDS on your any design.

Specifications

 new patented advanced led cooer technology is our  microgroove combined phase changed cooling technology ,it is best coolling than recent  any other cooler heat sink .

Cooling is conducted using the mechanism of combined phase-change heat transfer in high density micro-groove structure. Combined phase-change occurs when the liquid media in the structure accumulate sufficient heat. This mechanism significantly enhances the capability of heat removal, transfer and exchange. Also, the thermal diffusion with isothermal phase-change combines the evaporation and the cooling in the heat sink without any power consumption.
