Specifically, three cooling modules are independently arranged on the engine, the battery module and the generator 120, and are controlled through the independent cooling modules respectively, so that independent temperature control is realized, the engine, the battery module and the generator 120 are ensured to work within a reasonable working temperature range, and the long-time and efficient working of the power system of the hybrid truck is ensured.
As shown in fig. 2, the first cooling module 210 includes: a high temperature radiator 211, a mechanical fan 212, a liquid storage pot 213. Wherein a high temperature radiator 211 is provided at one end of the engine; the mechanical fan 212 is disposed between the high temperature radiator 211 and the engine 110; the liquid storage pot 213 is communicated with the high-temperature radiator 211 to realize the circulation exchange of the cooling liquid between the liquid storage pot and the high-temperature radiator 211.
In a preferred embodiment, a shield 214 is also included and is disposed over the mechanical fan 212 between the high temperature heat sink and the mechanical fan 212.
Specifically, the first cooling module 210 is used for controlling the temperature of the cooling fluid of the engine 110, and is composed of a high-temperature radiator 211, a mechanical fan 212, a liquid storage pot 213, a fan guard 214, a first cooling pipeline, and the like, so as to realize independent closed-loop control. The liquid storage kettle is used for storing cooling liquid, and the cooling liquid in the high-temperature radiator can enter the liquid storage kettle through a pipeline when preheated and evaporated, so that the effects of saving the cooling liquid and improving the cooling efficiency are achieved.
Generator 120 is driven coaxially with engine 110. During the starting process of the engine 110, the generator 120 corresponds to a starter function, and drags the engine to achieve the ignition starting speed. Under the condition of power deficiency of the battery module group, the engine can drive the generator to work together, the generator 120 can play a role in producing electric energy, then voltage conversion is carried out through the 05 high-voltage electrical box, and the voltage is transmitted to the battery module group for storage after the voltage conversion. When the air pressure of the air brake system approaches to the alarm value, the engine can be started to drive the air compressor to work until the air pressure of the brake system reaches the rated value to stop working. Compared with the traditional internal combustion engine truck, the common working condition load of the engine of the hybrid power truck is not high, and the thermal load of the engine 110 is also not high. In order to achieve the technical aim of light weight, the engine cooling module adopts light weight materials such as an aluminum radiator core body, a radiator plastic water chamber, a plastic air shield, a plastic liquid storage pot and the like. In order to achieve the technical aim of energy conservation, the fan adopts a silicone oil clutch temperature control mode, the temperature field of the engine compartment is monitored through a temperature sensing piece, and the rotating speed of the engine is controlled through the slip ratio. The hybrid power truck is mainly used for increasing Cheng Xunhang, cold starting and air source energy storage of a braking system, the engine generally works under a low-heat load working condition, the external large-circulation heat load is low, and the energy consumption of a radiator can be reduced by at least about 80%, so that energy conservation and consumption reduction are realized.
As shown in fig. 3, the second cooling module 220 includes: a low temperature radiator 221, an electronic fan 222, a high pressure expansion kettle 223 and a second electrically controlled water pump 224. Wherein the low temperature radiator 221; an electronic fan 222 provided at one end of the low-temperature heat sink 221; a high pressure expansion kettle 223 which communicates with the low temperature radiator through a second cooling line to effect a cooling fluid circulation exchange with the low temperature radiator.
In a preferred embodiment, a second electrically controlled water pump 224 is also included, which is disposed within the second cooling circuit.
The second set of cooling module group is used for controlling the temperature of the cooling liquid of the generator, the motor controller, the driving motor and the high-voltage electrical appliance box, and consists of a low-temperature radiator 221, an electronic fan 222, a second electric control water pump 224, a high-pressure expansion kettle 223, a second cooling pipeline and the like, so that independent closed-loop control is realized.
Generator 120 is coupled to engine 110 and the drive motor is integrated with the rear axle. The accelerator pedal signal directly controls the rotation speed of the driving motor, so that the vehicle speed control is realized. The internal components of the high-voltage electrical box and the motor controller are mainly circuit chips, and the working temperature is generally not more than 85 ℃. The internal components of the generator driving motor are mainly a stator and a rotor, and the working temperature of a coil winding is generally not more than 150 ℃. The cooling fluid flows through the above high pressure components and the temperature is typically no more than 60 ℃. The matrix integration is carried out from the angles of component functions, component working temperature requirements, pipeline length and the like, and the cooling liquid flowing path is reasonably distributed. Following the principle of arrangement from "low temperature to high temperature", the circulation path is as follows: radiator-expansion kettle-electronic water pump-high-voltage electrical box-motor controller-driving motor-generator. To shorten the cooling line length, a radiator and 330 an electronic fan are arranged on the left side of the frame. In order to improve the cooling efficiency and avoid generating excessive air, the radiator adopts a horizontal-direction cross-flow core body, and cooling liquid enters from the bottom and exits from the upper part. Because the cooling loop is longer, a large-lift brushless electronic water pump is adopted, and the phenomenon of over-temperature can not occur after the cooling liquid reaches the driving motor and the generator 120. The cooling module has the advantages of more components, long pipelines and more inflection points, air is easy to remain in the cooling loop, and the internal air is removed through the degassing port arranged on the expansion kettle, so that the phenomenon of over-temperature caused by overlarge air quantity is avoided.

In a preferred embodiment, the air conditioning and refrigerating device 300 is further included, and the air conditioning and refrigerating device communicates with the first cooling pipeline and the third cooling pipeline, so as to realize temperature control.
In a preferred embodiment, an air conditioning refrigeration unit includes: an air conditioner compressor; an expansion tank which communicates with the air conditioner compressor; an air conditioner condenser arranged at one side of the first cooling module; a refrigeration exchanger provided on the third cooling management side; an air conditioner evaporator disposed between the air conditioner condenser and the refrigeration exchanger. And the plate type condenser is arranged at one end of the battery module group and is communicated with the first cooling pipeline.
The optimum operating temperature of the battery module stack is typically between 20 ℃ and 35 ℃ and the maximum allowable temperature is typically no more than 55 ℃. The cooling module adopts a refrigerant to cool the cooling liquid under normal temperature and high temperature environment. And in a low-temperature environment, the temperature of the cooling liquid of the battery module group is raised by the cooling liquid of the engine, so that the service performance of the battery module group in the low-temperature environment is improved. The engine coolant loop is controlled by a water cut-off solenoid valve and is regulated based on the atmospheric environment temperature and the battery module group temperature.
The invention also provides a thermal management control method of the hybrid power truck, which comprises the following steps: when the temperature of the driving motor is higher than 85 ℃, the second cooling module works and reduces the temperature to 60 ℃; when the temperature of the battery module group is higher than 55 ℃, the third cooling module works and reduces the temperature to 20-30 ℃.
