Background
In designing efficient transmission systems, low energy consumption, and fast-charging vehicles, which involve an important unit of overall vehicle thermal management, most of the thermal management systems currently used in many electric and hybrid vehicles use multiple independent thermal management subsystems, including electric drive cooling, battery thermal management, and passenger compartment air conditioning systems. According to the design, heat distribution and transfer are not considered from the heat management efficiency of the whole vehicle, the energy efficiency ratio of a heat management system of the whole vehicle is low or the heat management consumes more power, so that a user complains that the endurance mileage of the whole vehicle is greatly reduced in a high-temperature and low-temperature environment. In a limited space of a vehicle body, heat requirements of multiple parts need to be considered, the energy efficiency ratio of a system is improved, and the reduction of heat management power consumption becomes a difficulty which needs to be overcome urgently by professional engineers.

Furthermore, the inlet of the three-way valve A is connected with the output pipeline of the water-cooled condenser, the first outlet of the three-way valve A is connected into the heating loop through a pipeline, and the second outlet of the three-way valve A is connected with the low-temperature radiator of the electrically-driven cooling loop through a pipeline.

Detailed Description
The technology is further explained in detail by the following figures and examples:
referring to FIG. 1, an architectural diagram of the basic subsystems within a thermal management architecture 100 of a typical electric vehicle is illustrated. The system comprises a 101 electric drive cooling loop, a 102 air conditioner cooling loop, a 103 battery thermal management loop, a 104 heating loop and a 105 control system. The vehicle thermal management architecture 100 allows for switching of the respective system loops based on environmental conditions and component operating characteristics, with the control system effecting switching of the different loops by controlling mode valves (three-way valves).
Further details in the above sub-loop are shown in fig. 2:
in particular, the system includes a three-way valve A227 between the water cooled condenser 202 of the desuperheating circuit 102 and the heating circuit 104 and the electrically driven cooling circuit 101. The three-way valve A227 when configured in the first mode has a valve inlet A in communication with a valve first outlet; when configured in the second mode, the valve inlet a is in communication with the valve second outlet. The three-way valve a227 is controlled by the controller to switch between a first mode, in which the water cooled condenser 202 is connected to the heating circuit 104, and a second mode, in which the electrically driven cooling circuit 101 is connected.
The electrically driven cooling circuit 101 of the present system includes a low temperature heat sink 223, power electronics, and at least one transmission drive component. The transmission driving component includes a driving motor and an electric control assembly 220, and the power electronic device includes a driving electronic assembly 218 and a charger assembly 219.
The electric drive cooling circuit 101 is used to cool the drive motor 220, which is the primary traction motor of the vehicle, as well as the electronic control assembly 220, the drive electronics assembly 218, and the charger assembly 219. Although a single drive motor is shown in the drawings, an electric vehicle using the present invention may be designed to use more than one single drive motor.
Also included in the electric drive cooling circuit 101 are a cooling water pump 217 for circulating the cooling liquid through the cooling circuit, a low temperature radiator LTR223 for discharging the heat to the ambient atmosphere, and a cooling water kettle 221. The system also includes an electronic fan 222 for forcing air through the low temperature radiator 223 when the air being passed through the low temperature radiator 223 is insufficient to achieve a desired level of cooling, for example, when the vehicle is not moving.
The desuperheating circuit 102 in the present system may use a refrigerant (e.g., R134a) compression system. As shown in the figure, the air-conditioning cooling circuit 102 comprises an electric compressor 201, the water-cooled condenser 202, an external condenser 205 and an evaporator 207 of a central air-conditioning system HVAC, the electric compressor, the water-cooled condenser, the external condenser and the evaporator 207 are sequentially communicated through a pipeline to form a circuit, a stop valve 203 and an electronic expansion valve EXV-1204 are connected between the water-cooled condenser and the external condenser in parallel, and an expansion valve E-TXV1206 with a stop function is arranged on an inlet pipeline of the evaporator 207.
In the second mode shown in fig. 4, the electric compressor 201 is used to compress the low temperature refrigerant vapor in the circuit to a high temperature vapor. Then, when the refrigerant vapor passes through the water cooled condenser 202, after heat exchange with the electrically driven cooling circuit 101, the refrigerant loses a portion of its heat, the shutoff valve 203 is opened, the EXV-1204 is closed, the refrigerant passes through the external condenser 205, and the refrigerant vapor loses a portion of its heat and then undergoes a phase change from vapor to liquid, which is maintained at a low temperature and a high pressure. Preferably, the heat dissipation performance of the external condenser 205 is improved by using the electronic fan 222. The liquid phase refrigerant then passes through the evaporator 207 and/or the battery cooler 209. In the mode configuration, refrigerant is coupled to the cabin evaporator 207 via a thermal expansion valve E-TXV1206 and to the battery cooler 209 via an expansion valve E-TXV1208 with a cut-to-function. Thermostatic expansion valves 206 and 208 control the flow rate of refrigerant to the evaporator 207 and battery cooler 209, respectively.
In the system, a battery water pump 225, a battery cooler 209 and a battery pack 224 are sequentially connected to the battery thermal management loop 103. The battery pack 224 includes a plurality of batteries. One or more battery water pumps 225 pump coolant through the battery pack 224, typically via heat transfer plates in communication with the battery pack, the coolant contained in the battery thermal management circuit being cooled via heat transfer between the coolant in the battery cooler 209, assuming that the thermostatic expansion valve 208 allows the coolant from the air conditioning cooling circuit 102 to pass through the battery cooler 209; or with the coolant in the heating circuit 104, assuming that the three-way valve B213 allows the coolant in the heating circuit 104 to pass through. The battery thermal management circuit 103 also includes a coolant reservoir battery kettle 226.
The heating loop 104 in the system comprises a water-cooled condenser 202, an electric heater 214, a warm air core 212 and a warm air pump 216. The output pipeline of the water-cooled condenser 202 is connected with the electric heater 214 through the three-way valve A227, the output pipeline of the electric heater is respectively connected with the warm air core body 212 and the battery cooler 209 through the three-way valve B213, and the output pipelines of the warm air core body 212 and the battery cooler 209 are connected with the water-cooled condenser 202 through the warm air water pump 215 to form a loop.
The electric heater 214 may employ a PTC heater, thereby ensuring that the temperature of the circuit can be maintained within its preferred operating range regardless of the ambient temperature. Warm air pump 215 pumps coolant through water cooled condenser 202, via the second outlet of three-way valve a227, through electric drive cooling loop 102; or via the first outlet of the three-way valve a227, the coolant flows through the warm air core 212 and/or the battery cooler 209, see fig. 3.
