When the first cooling system 116, the second cooling system 118 and the third cooling system 120 are independently arranged, because the operating temperatures of the first driving device, the energy storage device and the fuel reaction device are different, specifically, the operating temperature of the energy storage device 104 is between 20 ℃ and 30 ℃, the operating temperature of the fuel cell reactor 1062 is between 70 ℃ and 80 ℃, and the operating temperature of the driving device is lower than 60 ℃, by arranging the first cooling system 116 below the cab 110, the second cooling system 118 below the energy storage device 104 and the third cooling system 120 at the bottom of the chassis 108, the first cooling system 116, the second cooling system 118 and the third cooling system 120 are separately arranged, so that the first cooling system 116, the second cooling system 118 and the third cooling system 120 can separately and independently operate and can be separately controlled, not influence each other, further promoted cooling radiating efficiency.

In any of the above embodiments, further, as shown in fig. 1, the vehicle 100 further includes: a tarpaulin device 124 for covering the cargo box 112; a first end of the tarpaulin device 124 is connected with an end of the cargo box 112 and a second end of the tarpaulin device 124 is movable with respect to the first end to deploy or stow the tarpaulin device 124.

In this embodiment, the cargo box 112 can be shielded by the tarpaulin device 124, so that the cargo box 112 and the cargo in the cargo box 112 can be protected from direct sunlight or rainwater entering the cargo box 112 to damage the cargo in the cargo box 112.

Further, the tarpaulin device 124 may be connected to one end of the cargo box 112 at a first end and movable relative to the first end at a second end, thereby enabling the tarpaulin device 124 to be unfolded and folded for a worker to unfold or fold the tarpaulin device 124 as desired. Further, the tarpaulin device 124 may further be provided with a driver, and the driver is connected to the second end of the tarpaulin device 124, so that the tarpaulin device 124 can be automatically unfolded and stored, thereby facilitating the operation of the operator and improving the automation degree of the vehicle 100.
