Introduction&Application : 
鈼 BridgeLUX LED chip 鈼 COB LED light source 鈼 Technology of vacuum phase transformation for heat sink(flowing fluid in heat sink), much more performance of heat emission 鈼 Die-casting aluminum heat sink in big sizes 鈼 With frosted glass cover. Anti-glare design 鈼 Vacuum Phase Transition Technology, two-phase heat transfer involves the liquid-vapor phase change (boiling/evaporation and condensation) of a working fluid. While solid conductors such as aluminum, copper, graphite and diamond have thermal conductivities. Heat is transferred from the heat source (evaporator) to the heat sink (condenser) over relatively long distances through the latent heat of vaporization of a working fluid, namely, absorbed by vaporizing the working fluid. The thermal system has 3 major components: a vacuum tight, sealed containment shell or vessel, working fluid, capillary wick structure. They all work together to transfer heat more efficiently and evenly. Since the heat pipe contains a vacuum, the working fluid will boil and take up latent heat at well below its boiling point at atmospheric pressure. Water, for instance, will boil at just above 273掳K (0掳C) and start to effectively transfer latent heat at this low temperature.
