使用新制备的材料薄膜遮挡空间,将能提供冷却而无需输入功率。新制备的材料薄膜是人工超构材料,由玻璃微球聚合物和银制成。它发射红外线辐射,也反射太阳光。美国科罗拉多博尔德大学的团队在能源部300万美元项目经费的支持下,发明了这一新材料薄膜。辐射冷却是物体以红外辐射的形式散热的自然过程。在室温下所有材料都发射红外线,波长为5—15μm。然而,这样的过程通常不是很有效,因为外部热的因
Covering the space with a newly prepared material film will provide cooling without inputting power. The newly prepared material film is an artificial superconducting material made of glass microsphere polymer and silver. It emits infrared radiation and also reflects the sun’s rays. The team at the University of Colorado, Boulder, USA, invented the new material film with the support of a $ 3 million project funded by the Department of Energy. Radiative cooling is the natural process by which objects radiate heat in the form of infrared radiation. All materials emit infrared at room temperature with a wavelength of 5-15 μm. However, such a process is usually not very effective because of external heat
