The invention relates to a high heat insulation performance side window system for a high-speed train, the side window structure is a double-hollow structure, the outer layer is a sandwich structure formed by bonding a layer of European grey glass and a layer of ultra-white glass or a layer of Low E glass through a polymer film, and the European grey glass is located at the outdoor side; the middle layer is single-layer inorganic glass or single-layer Low E glass, or a sandwich structure formed by bonding two layers of inorganic glass through a polymer film, or a sandwich structure formed by bonding a layer of Low E glass and a layer of inorganic glass through a polymer film; the inner layer is of a sandwich structure formed by bonding a layer of ultra-white glass or a layer of Low E glassand a layer of European grey glass through a polymer film, and the European grey glass is located on the indoor side; in the sandwich structure, the Low E functional layers of the Low E glass face the hollow layer. The side window system has the advantages of being good in heat insulation and sound insulation performance, under the condition that the total weight and the total thickness of materials are not increased, compared with common hollow side window glass, the heat transfer coefficient K value can be reduced by 0.56 W/m < 2 >. K at most, and the weighted sound insulation amount is increased by about 2.0 db.
本发明是一种高速列车用高隔热性能侧窗系统,该侧窗结构为双中空结构,其中:外层为一层欧洲灰玻璃与一层超白玻璃或一层Low‑E玻璃经聚合物胶片粘接形成的夹层结构,欧洲灰玻璃位于室外侧;中间层为单层无机玻璃或单层Low‑E玻璃,或两层无机玻璃经聚合物胶片粘接形成的夹层结构,或由一层Low‑E玻璃与一层无机玻璃经聚合物胶片粘接形成的夹层结构;内层为一层超白玻璃或一层Low‑E玻璃与一层欧洲灰玻璃经聚合物胶片粘接形成的夹层结构,欧洲灰玻璃位于室内侧;上述夹层结构中,Low‑E玻璃的Low‑E功能层均朝向中空层。该侧窗系统具有隔热隔声性能好的特点,在材料总重量和总厚度不增加的情况下,相对于普通中空侧窗玻璃传热系数K值能够最多降低0.56W/m2·K,加权隔声量约提高2.0db。
