The driving motor controller 1 and the generator controller 2 which are connected in series are connected with the charger 3 and the generator 4 which are connected in series in parallel and then are connected with the water pump 5 in series, and the cooling liquid in the cooling system starts from the water pump 5, flows through the driving motor controller 1 and the generator controller 2 which are connected in series and the charger 3 and the generator 4 which are connected in series respectively, and flows back to the water pump. Here, the water pump 5 may be an electric water pump.
The utility model discloses an increase form hybrid vehicle's cooling system, through the driving motor controller 1 and the generator controller 2 with establishing ties and the parallelly connected back of machine 3 that charges and the generator 4 of establishing ties with water pump 5 establishes ties. Therefore, the system arranges the positions of the high-pressure components in the water paths according to the sensitivity to temperature and the heat productivity, groups the high-pressure components according to the principle that the resistance is approximately equal to form the parallel water paths, and then places the electronic water pump in the system trunk. Therefore, the water pump type selection is facilitated due to the fact that the lift requirement of the water pump is reduced, the water flow of the system trunk is increased, and the heat dissipation capacity of the whole system is improved.
Further, as shown in fig. 1, the cooling system further includes a driving motor 6 and a controller set 7 connected in series, wherein the driving motor 6 and the controller set 7 connected in series are connected in parallel with the driving motor controller 1 and the generator controller 2 connected in series.

Further, fig. 2 is a schematic flow diagram of coolant from a recirculating cooling loop in accordance with an embodiment of the present invention. As shown in fig. 2, the cooling liquid in the cooling system flows from the water pump 5, through the driving motor controller 1 and the generator controller 2 connected in series, the charger 3 and the generator 4 connected in series, the driving motor 6 connected in series and the controller assembly 7 connected in series, respectively, and flows back to the water pump 5.

The flow direction of the cooling liquid usually occurs under the condition that the temperature of the high-pressure components is not high, in this condition, temperature difference exists among the high-pressure components, and the condition that some high-pressure components generate heat accumulation due to the generation of more heat is adopted, so that the flow of the cooling liquid drives the heat to flow so as to enable the temperature of each high-pressure component to be approximately the same, and the heat is dissipated by natural convection of the high-pressure components and the ambient air. In this case, the power consumption of the water pump 5 is small, and at the same time, there is no power consumption of the cooling fan, so that energy can be effectively saved.

Further, as shown in fig. 1, the cooling system further includes a cooling fan 9 disposed near the radiator 8. When the heat dissipation requirement of the high-voltage component is large, the cooling fan 9 can be started to accelerate the heat dissipation.

Meanwhile, by the control method, different cooling loops can be automatically selected according to the cooling requirements of the high-voltage components to cool the high-voltage components, so that the energy consumption can be effectively reduced. Here, the first temperature may be 50 ℃.
