▎ 摘　　要

NOVELTY - The vehicle has a box body provided with refrigerating box (2), a condenser assembly and an evaporator assembly. A vehicle controller controls the condenser assembly and the evaporator assembly to work. A direct current-direct current (DC-DC) converter (6) is connected between a vehicle engine (7) and a lithium battery (5), where the box body is made of polypropylene material. The DC-DC converter is provided with a control signal input end, a power supply input end and a power supply output end. The control signal input end is connected with an automobile direct current output port. A power supply input end is connected with an engine power supply. The power supply output end is connected with the lithium battery (5). USE - Energy refrigerated vehicle i.e. energy refrigerator car. Can also be used for a car, a lorry, a sport utility vehicle (SUV), a bus, a watercraft, an aircraft, a hybrid vehicle, an electrical vehicle, a plug-in hybrid electrical vehicle and a hydrogen-powered vehicle. ADVANTAGE - The vehicle can act by the DC-DC converter, it can reasonably use lithium battery and vehicle engine power supply to supply power for refrigerated box, battery endurance ability is strong. The graphene material has very good conductivity, so that the evaporator has good heat exchange effect, so as to improve the refrigeration effect of the vehicle-mounted cold chain box, which can reach more effectively fresh-keeping effect. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an energy refrigerated vehicle.
