- Radiative cooling uses the space cold source to cool the object, and the radiative cooling film prepared based on its 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 radiation 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 cabin was studied by finite element analysis.The results show that the cooling film made of SiO2 as passive radiation material has obvious cooling effect on passenger cabin.In the ambient temperature of 308.15K, the theoretical cooling temperature is 6.7K.When radiative cooling film is applied to automobiles, the cooling value of passenger cabin body, seat, instrument panel and other parts reaches 2.2K-5.1K, among which 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 certain 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 automobile and alleviate the energy crisis.
