A method of enhancing a freezing capacity of a low-temperature delivery vehicle is that cool cold devices by a freezing machine, each of which has an eutectic material therein, to a temperature lower than eutectic temperatures of the cold devices, and then put the cold devices in a chamber of a vehicle, which the vehicle has a refrigerator to provide a cold airflow to the chamber via an outlet on a wall of the chamber. The cold devices have to be taken out after a predetermined period and cooled again to recycle. The low-temperature delivery vehicle of the present invention has a van body having a chamber therein, a refrigerator having an outlet on a wall of the chamber to provide a cold airflow to the chamber, and a plurality of cold devices in the chamber of the van body.
