Summary:

Radiative cooling uses the cold space source to cool the object. The radiative cooling film prepared based on the principle can reduce the fuel consumption of automobile air conditioning refrigeration.In this paper, according to the passive radiative cooling principle, taking SiO2 as the radiative cooling film of infrared radiation material, the theoretical cooling value of the passenger compartment of the automobile is calculated and analyzed based on the heat balance equation. The influence of radiative cooling film on the temperature field of passenger cabins was studied by finite element analysis. The results show that the cooling film made of SiO2 as passive radiation material has an apparent cooling effect on the passenger cabins. At the ambient temperature of 35.15°C, the theoretical cooling temperature is 6.7K. When the radiative cooling film is applied to automobiles, the cooling value of the passenger cabin body, seat, instrument panel, and other parts reaches 2.2K-5.1K. The cooling peak of 5.1K occurs on the seat. At the same time, the cooling effect in the passenger cabin is positively correlated with the ambient temperature in a specific range. The research results of this paper can promote the application of passive radiative cooling film in the field of automobile cooling, reduce the energy consumption of automobiles and improve the energy crisis
