The water is heated by the heater 2 and then is conveyed to the vehicle interior heat radiator 3, and then flows back to the heater to form circulation heating, the water tank is connected into the circulation through the water outlet 12 to supplement water, and a plurality of water valve control loop switches can be arranged in the necessary places in the system. Preferably, the water tank may be connected to the waterway through a tee junction before the heater. The circulating power of the waterway system can be provided by the heater 2 with the pump module, and an independent pump module can be set up. Compared with the traditional passenger car, the warm air system of the pure electric passenger car does not pass through the engine system, the degassing requirement is not strict in the past, and the design utilizes the point to liberate the position of the water tank, so that the water tank is not higher than the waterway system, and the water tank can be arranged at a lower position in the passenger car.
For further optimization of the above embodiment, the heater 2 includes a pump module 21 and a heating module 22, where the pump module 21 absorbs water in the fluid pipeline, flows to the in-vehicle heat dissipation device 3 after being heated by the heating module 22, and returns to the heater to form a circulation heating waterway, and the water tank supplements water to the circulation heating waterway through a water outlet of the water tank. Considering to simplify the skeleton texture, improve commonality, modularization and installation manufacturability, further adopting the modularized design, novel warm braw component sets up to in the warm braw integration cabin 4, water tank 1 and heater 2 set up in the warm braw integration cabin 4, warm braw integration cabin 4 can set up at passenger train locomotive, tail or bottom of a vehicle. The fluid pipeline from the water tank in the warm air integration cabin to the heater is connected to the heat dissipation device in the car everywhere in the passenger car, and then flows back to the warm air integration cabin pipeline, wherein the fluid pipeline from the water tank to the heater section is greatly shortened, the pipeline can be saved by more than 10 meters according to the length of about ten meters of a common passenger car, corresponding water and supporting pieces are reduced, and the total reduction weight is more than 15kg. Meanwhile, the water pipeline does not need to pass through the bus framework and the power battery module, so that potential safety hazards caused by water leakage are avoided, and meanwhile, the installation of a warm air system can be completed at the same station in the bus production process, and the modularized production is realized.
Furthermore, the preferred embodiment of the passenger car to which the novel warm air arrangement is applied as shown in fig. 2 has a passenger compartment floor level 6, the warm air integration compartment 4 being arranged below the floor level 6.
