HDL-01---LED Working Light Heat Pipe Principle                                                    Phase change heat pipe principle and capillary action, so that the heat transfer efficiency itself higher than the same copper material hundreds of times to several thousand times. Vacuum heat pipe is a copper pipe, which is the injection of working liquid heat transfer medium. 熱導管利用相變原理和毛細作用，使得它本身的熱傳遞效率比同樣材質的純銅高出幾百倍到數千倍。熱管是一根真空的銅管，裡面所注的工作液體是熱傳遞的媒介。   Nano Graphene Applications     Graphene is currently the world's thinnest but also the most hard nanomaterials, thermal conductivity of up to 5300 W / m · K, higher than that of carbon nanotubes and diamond, the electron mobility at room temperature Chaoguo 15000 cm2 / V · s   奈米石墨烯應用   石墨烯目前是世上最薄卻也是最堅硬的奈米材料,導熱系數高達5300 W/m·K，高於碳奈米管和金剛石，常溫下其電子遷移率超過15000 cm2/V·s
