If the arrangement of one electric three-way valve is the same as that of the electric three-way valve D in fig. 3, the arrangement of the three connection ports of the electric three-way valve at this time coincides with the three connection ports D1, D2, D3 of the electric three-way valve D.

In detail, when the thermal management system of the embodiment is used, the cycle process of the heat pump assembly is as follows: compressor 1 → liquid condenser 2 → thermostatic expansion valve 3 → liquid evaporator 4 → compressor 1. And, according to car owner's settlement demand, and battery thermal management demand and the ambient temperature outside the car, the heat pump package is when mainly refrigerating, can be according to the operating time of the temperature control compressor 1 of cold water heat preservation jar 6, then can be according to the operating time of the temperature control compressor 1 of hot water heat preservation jar 11 when mainly heating.
When the carriage has a cooling demand, the cycle is as follows: the cold water pump 5 → the liquid type evaporator 4 → the electric three-way valve G (G1-G3) → the cold air core 16 → the electric shutoff valve X6 → the cold water thermal insulation tank 6 → the cold water pump 5. Wherein, G1-G3 in the electric three-way valve G (G1-G3) indicates the communication between the G1 and G3 ports in the electric three-way valve G, and the following description of the electric three-way valves represents the same meaning.
When the battery has a cooling demand, the cycle is: the cold water pump 5 → the liquid type evaporator 4 → the electric three-way valve G (G1-G3) → the electric three-way valve B (B3-B1) → the battery heat-exchange water pump 7 → the battery heat exchanger 8 → the electric cutoff valve X2 → the electric three-way valve a (a1-A3) → the cold water insulated tank 6 → the cold water pump 5.
When the temperature reduction and the cooling demand are simultaneously generated in the carriage and the battery, the electric stop valve X6 and the electric stop valve X2 are opened.
In addition, when cooling and cooling needs are met, the heat dissipation cycle of the liquid condenser 2, the motor and the controller is as follows: the heat-radiating water pump 12 → the electric three-way valve E (E2-E1) → the motor heat exchanger 13 → the electric three-way valve D (D2-D1) → the radiator 14 → the electric three-way valve C (C1-C3) → the electric shutoff valve X4 → the liquid condenser 2 → the heat-radiating water pump 12.
In the above heat dissipation cycle, if the liquid condenser 2 in the heat pump assembly has no heat dissipation requirement, the heat dissipation cycle at this time is: the heat-radiating water pump 12 → the electric three-way valve E (E2-E1) → the motor heat exchanger 13 → the electric three-way valve D (D2-D1) → the radiator 14 → the electric three-way valve C (C1-C3) → the electric shutoff valve X5 → the heat-radiating water pump 12.
When the heating demand is provided in the carriage, the circulation is as follows: the hot water pump 10 → the heater core 17 → the electric shutoff valve X1 → the electric heater 9 → the hot water thermo-tank 11 → the check valve 18 → the liquid condenser 2 → the electric shutoff valve X5 → the electric shutoff valve X3 → the hot water pump 10.
When the battery has a heating demand, the cycle is as follows: the hot water pump 10 → the electric three-way valve B (B2-B1) → the battery heat-exchange water pump 7 → the battery heat exchanger 8 → the electric shutoff valve X2 → the electric three-way valve a (a1-a2) → the electric heater 9 → the hot water thermo-tank 11 → the check valve 18 → the liquid condenser 2 → the electric shutoff valve X5 → the electric shutoff valve X3 → the hot water pump 10.
When the interior of the compartment and the battery have heating and heating requirements at the same time, the electric stop valve X1 and the electric stop valve X2 are opened.
Furthermore, when there is a heating and warming demand, the circulation at the liquid evaporator 4 in the heat pump assembly is: cold water pump 5 → liquid evaporator 4 → electric three-way valve G (G1-G2) → electric three-way valve C (C2-C1) → radiator 14 → electric three-way valve D (D1-D2) → motor heat exchanger 13 → electric three-way valve E (E1-E2) → electric three-way valve F (F2-F1) → cold water pump 5.
Through the circulation at the liquid type evaporator 4, the effect of heat recovery can be achieved through the absorption of the heat of the motor and the controller. However, when the temperature of the motor and the controller is too low to be lower than the set temperature, the electric three-way valve D in the cycle (D1-D2) needs to be switched to (D1-D3) to ensure that the motor and the controller operate in an efficient environment.
In addition, in the thermal management system of the embodiment, it should be noted that, in use, the cooling fan 15 at the radiator 14 performs air volume adjustment according to the temperature of the radiator 14, the ambient temperature and the vehicle speed, and each water pump may perform flow adjustment or start-stop control according to the requirement. The electric heater 9 is properly turned on according to the heating and heating temperature requirements to compensate the temperature, but from the viewpoint of energy saving, the heat recovery of the motor and the controller should be preferentially utilized in use, so that the turning on of the electric heater 9 is reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
