摘要：采用碳纤维纸为发热元件,石墨膜为导热材料,与木质材料复合制备电热实木复合地板基材,研究石墨导热膜的引入对地板基材的电热效应、温度分布均匀性、电-热辐射转换效率的影响。结果表明:不同功率密度条件下,引入石墨导热膜的电热实木复合地板基材表面温度低于对照样,但随功率密度增加表面温度降幅呈逐渐降低趋势,200W/m^2时下降了13.82%,500W/m^2时仅下降2.43%。表面温度均匀性提升明显,起到良好均热效果,可降低发热后表面温度的聚热程度。当功率密度由200W/m^2增加至500W/m^2时,温度均匀性由8.95%增加至44.30%;电-热辐射转换效率也低于对照样,最高降幅为17.98%。
Carbon fiber paper and thermal conductive graphite film were used to produce electrothermal parquet flooring substrate to investigate the influence of graphite film on the electrothermal effect,temperature distribution uniformity and electric-to-radiant power transfer efficiency.The surface temperature of electrothermal parquet flooring substrate with thermal conductive graphite film was lower than the control group under different power density conditions.With the increasing of power density,the surface temperature decreasing degree showed a decreasing trend compared to the control group,which decreased by 13.82%at power density 200 W/m^2,but only decreased by 2.43%at power density 500 W/m^2.The uniformity of surface temperature was obviously improved and showed a better uniform heat effect,further reduce the heat accumulation degree of surface temperature after heating electrothermal parquet flooring substrate.When the power density is increased from^200 to 500 W/m^2,the temperature uniformity is increased from 8.95%to 44.30%.However,the electric-to-radiant power transfer efficiency was also lower than the control group,and its highest rate of decline was 17.98%.
