[Text / high-tech reporter Xiong Yuheng] Previously, LED radiator materials used aluminum alloy, its low cost, simple processing, excellent thermal conductivity make it occupy the mainstream position of LED radiator materials for a long time. Nowadays, with the continuous advancement of LED heat dissipation technology, new heat-dissipating materials including heat-conductive plastics and plastic-coated aluminum have also been continuously developed.
It is generally believed in the industry that the thermal emissivity of thermally conductive plastics is significantly better than that of metallic materials, so the thermal radiation capability of thermally conductive plastics is much better than that of metallic materials of the same conditions. However, the drawback of thermal plastics is that they are not as good as metal in terms of heat transfer, so the overall heat dissipation performance is slightly worse.
“The plastic aluminum radiator can quickly conduct heat by using aluminum, and the plastic can quickly adapt to the heat dissipation characteristics, and fully combine the advantages of the two in heat dissipation.†Puwan Optoelectronics Thermal Technology Co., Ltd. (hereinafter referred to as “Puwan Optoelectronicsâ€) General Manager Tao Tao mentioned that the use of thermal plastics as a carrier, coupled with the inner wall of aluminum metal, can greatly enhance the thermal conductivity of thermal plastics.
The heat-dissipating material of the aluminum-wrapped plastic is the hot-packed aluminum heat-dissipating material that is currently being fired. In recent years, Puwan Optoelectronics has focused on the R&D and production of plastic-coated aluminum heat-dissipating materials, and has achieved very good results. At present, it has applied for invention patents (patent number is 3.3).
“This kind of plastic-coated aluminum heat-dissipating material has been greatly improved in various properties.†Tao Tao mentioned that the first is the high transmittance of the lampshade, which can achieve more than 90%. Secondly, the thermal conductivity of the radiator can reach 5.0 or more; again, good insulation, high pressure resistance up to 4000 volts or more; finally, high temperature resistance up to 120 °C.
2014 (5th) High-tech Golden Globe Award--The annual LED good product selection has been opened, and has entered the enterprise registration stage (June 7-July 31). Known as the “Oscar for the LED industryâ€, this year, it attracts many well-known companies from the industry. This time, Puwan Optoelectronics will participate in the Golden Globe Awards with the model WG-QP-010 plastic-coated aluminum heat-dissipating material.
Yan Tao also mentioned that the company's series of plastic-coated aluminum heat-dissipating materials can completely replace the metal-aluminum shell, which is heat-insulating and flame-retardant. At the same time, it is safe, beautiful and light, effectively achieves high efficiency and low energy consumption, achieving energy saving and environmental protection effects. The safety regulations have been well received by well-known domestic and foreign companies, and the market prospects are very clear.
