Road transportation is an important part of cold chain logistics. In order to study how the flow field and the temperature of the cold source influence the temperature field in the fully loaded car, computational fluid dynamics (CFD) technology is used to model and numerically simulate the mechanical refrigerated truck, dry ice refrigerated truck, and cold storage refrigerated truck. It found that there was a positive relationship between the cold source temperature and the air in the compartment. The velocity of air contributed to the uniformity of the air temperature in the truck. The location distribution of the cold source also had a certain effect on the temperature distribution of the air in the compartment and the surface temperature of the frozen product. Due to the difficulty of obtaining cold plate refrigerated trucks, the temperature field in vehicles was verified by experiments with mechanical refrigerated trucks and dry ice refrigerated trucks. The maximum absolute errors of each temperature measurement point are 0.94 °C and 1.15 °C, indicating that the numerical simulation results are reliable.
