Background
The fuel cell automobile has a wide development prospect in the future due to the sustainability of energy and better driving range. Currently, the fuel cell suitable for automotive use is PEMFC, and companies in yota/modern times have begun to commercially operate PEM fuel cell vehicles.
At present, a heater is needed to quickly raise the temperature of the fuel cell when the temperature of the fuel cell automobile is low (less than or equal to 0 ℃) so as to ensure the normal work of the fuel cell. Most of the current solutions are implemented using a PTC heater. When the fuel cell vehicle works normally, a thermostat is also needed to adjust a cooling liquid circulation path, so that the cooling liquid can be heated quickly; meanwhile, when the temperature of the cooling liquid is high, the cooling liquid can flow to the radiator to dissipate heat.
Currently in fuel cell thermal management systems, the heaters are generally arranged in small cycles, as shown in particular in fig. 1, or in branches in parallel with the stack, as shown in particular in fig. 2. The former heater 5 will consume the power of the cooling water pump 2 in small circulation, and reduce the flow rate of the small circulation, which will result in that the loading slope of the galvanic pile 1 can not be made higher, wherein the one-way valve 4 is used for adjusting the flow direction of water; when the temperature needs to be reduced, the heat is dissipated through the radiator 6, and the water flow rate of the temperature reduction is adjusted through the temperature regulator 3. In the latter, in order to reduce the diversion of the branch to the electric pile 1, an additional on-off valve is generally required to be added, or a larger water pump 2 is selected, and meanwhile, the heating power of the heater 5 in the branch is reduced due to the reduction of the flow passing through the heater 5; when the temperature needs to be reduced, the working principle of the radiator 6 and the thermostat 3 is the same as that of fig. 1, and the details are not described here.
