[0002] Cold chain transportation refers to the transportation process in which the transported goods are kept at a certain temperature throughout the entire transportation process. Cold chain transportation is one of the main modes of transportation for agricultural and sideline products. It can provide good preservation effects for agricultural and sideline products and prevent them from rotting and deteriorating during transportation. The common cold chain transportation method is to stack the agricultural and sideline product packaging boxes and store them in the carriage, using the low-temperature refrigeration effect in the carriage to maintain the temperature.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing cold chain transportation preservation system preserves the goods in the cold chain vehicle, it generally uses a refrigeration device to exchange heat in the vehicle compartment to achieve the function of cooling and preservation. However, this cooling method cannot evenly cool the vehicle compartment. When the goods are far away from the refrigeration device or the goods are stacked together, the refrigeration device has a poor cooling effect on them. Utility Model Content
