The invention belongs to the technical field of automobile parts, and particularly relates to glass capable of reducing heat loads of a new energy automobile and a vehicle, the glass comprises a glass layer and a radiation layer, the radiation layer is arranged on the glass layer, the glass layer has the transmittance of at least 80% for solar radiation within the wavelength range larger than 300 nm, and the radiation layer is arranged on the glass layer. The radiation layer has a reflectance of at least 78% for solar radiation in a wavelength range greater than 300 nm, and has a transmittance for visible light. The invention aims to solve the problems that in the prior art, the prior art cannot simultaneously meet the requirements of low in-vehicle darkness and need of auxiliary lighting due to low visible light wave band transmittance of vehicle glass, and the defrosting efficiency of a front vehicle window can be influenced due to the fact that multiple layers of glass are heavy in weight and high in cost. Under the condition that the weight of the glass is not increased, the heat insulation performance of the glass can be improved, so that the heat load in an automobile is reduced.
本发明属于汽车部件技术领域,具体涉及一种降低新能源汽车热负荷的玻璃及车辆,包括玻璃层和辐射层,所述辐射层设置在玻璃层上,所述玻璃层对大于300nm波长范围内的太阳辐射具有至少80%的透过率,所述辐射层对大于300nm波长范围内的太阳辐射具有至少78%的反射率,并对可见光具有透过率。其目的是:用来解决背景技术中指出的现有技术无法同时满足车辆玻璃可见光波段透过率低导致的车内暗度较低,需要辅助照明,且多层玻璃重量大,成本高,还会影响前车窗除霜效率的问题,通过本发明中提供的技术方案,在玻璃不增加重量的情况下,能够提高其隔热性能,从而降低汽车内部的热负荷。
