改善散热冷却涂层的散热和温度均匀性
Improving Heat Dissipation and Temperature Uniformity in Radiative Cooling Coating
中文简介
在具有高集成度和小型化的电子设备中,散热已成为关键问题。作为有效的热传递方式,辐射冷却引起了这些设备的极大关注。但是,由于散热不良和温度不均匀,限制了基于辐射冷却涂层的散热。在此,提出了一种具有良好的导热性和强散热性的协同增效策略,以提高散热冷却涂层的散热和温度均匀性。通过该策略,设计了一种由聚偏二氟乙烯-共六氟丙烯和石墨组成的复合涂层。通过实验表明,白天复合涂层的散热提高了7%。大幅度降低温度约15。在白天,使用复合涂层在热源表面获得5°C的温度。2°C以内的复合涂层表面的温差表明,辐射冷却涂层的温度均匀性得到了改善。

attention in these devices. However, heat dissipation based on radiative cooling coating is limited by the poor heat spreading and temperature nonuniformity. Herein, a synergic augment strategy of excellent thermal conduction and strong thermal emission is proposed to improve the heat dissipation and temperature uniformity of radiative cooling coating. By the strategy, a composite coating consisting of poly(vinylidene
