Abstract

The invention belongs to the technical field of fuel cell vehicles, and discloses a whole vehicle cooling system of a fuel cell commercial vehicle, which comprises a fuel cell engine cooling subsystemand a driving motor cooling subsystem which are intensively arranged at the front end of a cabin, wherein the fuel cell engine cooling subsystem comprises a left radiator, a right radiator, a left electric fan, a right electric fan, a first electric water pump, a PTC heater, a temperature regulator and a fuel cell engine; the drive motor cooling subsystem comprises an intermediate motor radiator,a second electric water pump, a motor controller, a DCDC controller, a drive motor and a motor cooling fan arranged on one side of the intermediate motor radiator, wherein the intermediate motor radiator, the second electric water pump, the motor controller and the DCDC controller are connected in series. According to the system, two sets of independent cooling subsystems are used for carrying out thermal management on a fuel cell engine, a power motor, a motor controller and a DCDC of the fuel cell commercial vehicle respectively; the two subsystems are independently controlled and arrangedat the front end of a cabin in a centralized mode, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, in particular to a vehicle cooling system for fuel cell commercial vehicles. Background technique [0002] Fuel cell electric vehicle means that the power system is mainly composed of fuel cell stack, energy storage box (hydrogen bottle), motor, power battery and control system. The energy of the fuel cell is converted into electrical energy through the chemical action of hydrogen and oxygen, and its energy conversion efficiency can be as high as 60%-70%. The chemical reaction process of fuel cells does not produce harmful substances, so fuel cell vehicles are pollution-free vehicles, and the energy conversion rate of fuel cells is 2-3 times higher than that of internal combustion engines. Therefore, in terms of energy utilization and environmental protection, fuel cell vehicles are One of the trends in the development of new energy vehicles in the future. [0003] The theoretical ef...
