技術說明

本發明為具煙囪孔道之被動式暨主動式新穎複合材料LED燈具散熱器，係由石墨粒、塑膠粒、金屬粉末、樹酯等，依特定比例以真空注型技術射出成型，本發明的單位質量熱傳能力優於鋁合金散熱座，在自然對流與強制對流時，本發明的單位質量熱傳能力超過鋁合金散熱座，本發明的重量與價格均遠低於傳統金屬散熱座，是極有潛力的散熱座材質。此外，本發明的構型特徵為一中空圓柱體，圓柱體外圍具有多個片狀鰭片幅射狀排列，圓柱體內部可裝置電子控制裝置，在圓柱體圓形壁中有多個中空孔，下方與上方分別有進、出氣口，因為溫度差可形成煙囪效應，增加自然對流散熱能力。 This invention is a cooling device of LED lamp consisting of chimney channels and active LED heat sinks . It is made of graphite particles, plastic particles, metallic powders and latex by the vacuum injection molding technique with the specified ratio of mixtures. This invention has higher cooling capability per unit mass by comparing with aluminum alloy one. The cooling capability per unit mass of the present graphite-based invention is higher than that of aluminum alloy heat sink in natural convection and forced convection states. Both the total mass and cost of the present graphite-based invention are much lower than the traditional metallic heat sink, suggesting that this invention is very potential. Besides, this invention designs several short pins on the back surface of the LED base plate. This base plate is used to be the part of mold when this invention is modeling by the vacuum injection technique.
