Abstract: To solve the problem of thermal comfort of passengers, experiment research was conducted in Qionghai, Hainan Province of China, to analyze the rule of thermal load of vehicle seats and the influencing factors. In the experiment, a black domestic car was exposed to extreme hot and humid climate, and the parameters of the thermal environment around the car were recorded. The thermal grid numerical method, which is characterized by high efficiency and accuracy in the analysis of the wall temperature of vehicles, was adopted to analyze the thermal load of the whole vehicle model. The change of heat flux during heat transfer process was analyzed by simulation, and the effects of the thermal properties of vehicle seats, transmittance of the glass window, the parking location and other factors on the surface temperature of the vehicle seats were investigated. The results indicate that, reasonable selections of the thermal properties of the seats, the transmittance of the front windshield and the parking site can effectively reduce the surface temperature of the seats, thus, improving the thermal load condition.

Key words: vehicle engineering, thermal load, thermal grid numerical method, vehicle seats, solar radiation
