The paper aims to propose a new external thermal insulation heating system and explore its comprehensive perfor-mance. With the cold chain logistics as the breakthrough point, a new thermal insulation heating system was proposed to elaborate the comprehensive performance of the new thermal insulation heating system from physical performance analysis, process perfor-mance practice, comprehensive performance testing, application performance verification and other aspects in combination with the basic theory of heat transfer. After the thermal-dynamic balance of the new thermal insulation material was achieved, the rela-tionship curve between heat leakage rate and temperature difference was relatively stable and had no big fluctuation point. At the same time, the diesel consumption of the new heating system was reduced from 19.3 L/h to 17.2 L/h, and the average heating time was reduced by 1 h. The heating efficiency of the new external thermal insulation heating system is greatly improved, and the heat loss is further reduced, while the loading and unloading efficiency is accelerated.
