The invention relates to the technical field of fuel cells, in particular to a water pump arrangement system of a fuel cell vehicle, the fuel cell vehicle comprises a front cabin, a longitudinal beam and a headlamp are arranged in the front cabin, and the system comprises a main heat dissipation delivery pump, an auxiliary heat dissipation water pump and a support; the support is connected to the side edge of the longitudinal beam and located below the headlamp. The support is provided with a first containing position and a second containing position which are arranged up and down, the auxiliary heat dissipation water pump is arranged on the first containing position, and the main heat dissipation water pump is arranged on the second containing position. The arrangement of the two water pumps is integrated, the arrangement position is adjusted to the space outside the longitudinal beam of the front cabin of the vehicle body and below the headlamp from the traditional position below the front cabin, and the space occupied by the raw water pumps in the front cabin is reserved for the fuel cell system and the electric driving system, so that the physical problem of tense space arrangement is solved, and the service life of the water pumps is prolonged. And by changing the arrangement position of the water pump, the noise in the cabin is reduced, and the performance of the whole vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to a water pump arrangement system of a fuel cell vehicle. Background technique [0002] In the design process of fuel cell vehicles, there are two sets of heat dissipation systems, one is the main heat dissipation system, which is mainly responsible for the heat dissipation of the fuel cell system; the other is the auxiliary heat dissipation system, which is responsible for the motor, air compressor controller, DCDC, intercooler, Heat dissipation of other components. Due to the performance of the fuel cell system and the motor and other components, the heat dissipation needs are large, the rated power of the water pump is high, the volume of the water guide pump is large, and the number of water pumps is required, resulting in a large space in the front cabin. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a way t...
