A semi-trailer model loaded with refrigerated containers. Semitrailer is used to transport refrigerators and carry out trunk distribution. A semitrailer can carry multiple refrigerators, each of which corresponds to a medium-sized terminal customer. The last delivered refrigerated container is placed in the innermost part; the first served refrigerated container is placed on the outermost part for easy loading and unloading. Each refrigerator corresponds to a medium-end customer and is delivered without requiring boxes to be resorted and repacked. They are taken directly from the delivery vehicle that is responsible for regional distribution to customers. Each refrigerated container can be fixed with a buckle, easy to transport. This way saves human resources and improves the efficiency of distribution
