The thermostat 6 is a three-way structure and comprises a water inlet pipe, a first water outlet pipe and a second water outlet pipe, wherein the water inlet pipe is directly connected with the pipeline. The first water outlet pipe is communicated with the heat dissipation module 10, so that water flowing out of the first water outlet pipe can be subjected to heat dissipation and cooling through the heat dissipation module 10; the water outlet of the heat dissipation module 10 is connected with the first water pump 2. The design enables the first water pump 2, the engine, the thermostat 6 and the heat dissipation module 10 to be connected in series to form a circulation loop. And a second water outlet pipe of the thermostat 6 is connected with the warm air core body 4, cooling water coming out of the second water outlet pipe can be heated and heated after entering the warm air core body 4, and the heated cooling water returns to a fluid channel of the engine through the first water pump 2. The design enables the first water pump 2, the engine, the thermostat 6 and the warm air core 4 to be connected in series to form a circulation loop. Since the thermostat 6, the heater core 4, and the heat dissipation module 10 can be purchased directly, a detailed description of the internal structure thereof will not be provided.
In order to adjust the temperature of the engine oil in the engine, the power assembly system is further provided with an engine oil cooler 5, the engine oil cooler 5 is made of metal with good heat conduction performance, the interior of the engine oil cooler comprises an independent oil passage and a water passage, the oil passage is used for the engine oil of the engine to flow through, the water passage is communicated with the fluid passage on the cylinder body 3, and cooling water flowing out of the fluid passage of the cylinder body 3 can enter the engine oil cooler 5 and exchange heat with the engine oil in the water passage.

The thermo-valve 12 can be directly purchased, and thus a detailed description of its specific structure will not be given.
Because the gearbox 13 can generate more heat during working, the gearbox oil cooler 11 is connected to a pipeline between the engine oil cooler 5 and the warm air core 4; when the temperature in the gearbox oil cooler 11 is higher than the preset temperature, the temperature control valve 12 is automatically opened, water coming from the engine oil cooler 5 can pass through the gearbox oil cooler 11, and flows into the warm air core 4 after taking away a part of heat, so that the heating efficiency of the warm air core 4 is improved.
For a turbocharged vehicle, the power assembly system further comprises a turbocharged cooler 8 and a second water pump 7, wherein a water inlet of the second water pump 7 is communicated with the fluid channel of the cylinder 3, a water outlet of the second water pump is communicated with a water inlet of the turbocharged cooler 8, and a water outlet of the turbocharged cooler 8 is connected with a water inlet of the warm air core 4.

The second sensor is arranged on the engine and used for detecting the temperature change of the engine in real time; when the engine temperature is higher than the preset temperature, the first water pump 2 operates and the cooling system operates.
In addition, the power assembly system further comprises an expansion water tank 9, half kettle cooling water is contained in the expansion water tank 9, the upper space of the expansion water tank is communicated with the second water pump and the heat dissipation module, and the lower portion of the expansion water tank is communicated with the water inlet of the first water pump.

The working principle of the powertrain system is described below by the low-temperature environment and the high-temperature environment, respectively:
in a low-temperature environment, for example, when the ambient temperature is-30 ℃, when the temperature of the engine water is lower than 70 ℃, the first water pump 2 does not work, the whole cooling circulation circuit does not operate, and the temperature of the water in the engine rises rapidly. When the oil temperature of the gearbox 13 is lower than 70 ℃, a loop of the temperature control valve 12 flowing through a cooler of the gearbox 13 is disconnected, cooling water directly flows into the warm air core 4, and the oil temperature in the gearbox 13 is quickly increased. When the ambient temperature is-30 ℃, the opening temperature of the thermostat 6 is controlled to be 102 ℃, and meanwhile, the opening height of the thermostat 6 is adjusted to control the water temperature of the engine to be shifted.
In a high temperature environment, for example, the ambient temperature is 40 ℃, when the engine temperature is higher than 70 ℃, the first water pump 2 works, and the cooling system operates. When the oil temperature of the gearbox 13 is higher than 70 ℃, a cooling loop of the temperature control valve 12 flowing through the gearbox 13 is opened, and the temperature of the whole engine water is controlled to cool the gearbox 13. When the ambient temperature is 40 ℃, the opening temperature of the thermostat 6 is controlled to be 90 ℃, and the opening height of the thermostat 6 is adjusted at the same time, so that the rising rate of the water temperature of the engine is controlled, and the engine reaches an equilibrium state as soon as possible.
