The invention discloses a cooling system for a fuel cell extended-range electric vehicle, which belongs to the technical field of electric vehicle design. The cooling system includes: a fuel cell main unit and a first temperature sensor arranged inside the fuel cell main unit, an ion separator, a first electronic water pump, a first radiator, a first expansion tank and an electric drive for cooling the electric drive system Cooling system; one end of the first expansion tank is connected to one end of the first electronic water pump, the other end of the first electronic water pump is connected to one end of the first radiator; the other end of the first radiator is connected to one end of the fuel cell main unit, and the fuel The other end of the main battery is connected with one end of the ion separator, and the other end of the ion separator is connected with one end of the first radiator. In the present invention, the fuel cell system is cooled by the first radiator, which avoids the impact on the fuel cell host due to excessive temperature.
Description
technical field [0001] The invention relates to the technical field of electric vehicle design, in particular to a cooling system for a fuel cell extended-range electric vehicle. Background technique [0002] In recent years, the market share of new energy vehicles has been increasing, showing a blowout development. The future automobile market will develop in the direction of environmental protection and pollution-free new energy vehicles; however, it is limited by the development of the battery industry. Bottleneck, the cruising range of new energy vehicles cannot meet the demand. In this case, adding a range extender to new energy vehicles has become the ice-breaking choice for new energy vehicles. [0003] In order to reduce air pollution, a fuel cell system is generally used as a range extender to extend the range of new energy vehicles. Among them, the fuel cell system includes a fuel cell host, which generates electricity through the fuel cell host, and transmits the...
