The following detailed description is provided to further explain the claimed embodiments of the present invention, so as to enable those skilled in the art to more clearly understand the claims. The scope of the present invention is not limited to the following specific embodiments. It is intended that the scope of the invention be limited not by the specific embodiments described below, but rather by the claims appended hereto.
As shown in fig. 1, an automobile cooling control system includes an engine cooling system, an air-conditioning refrigeration system, a battery cooling system, and a three-medium heat exchanger 11, where the three-medium heat exchanger 11 includes a first heat exchange channel 111, a second heat exchange channel 112, and a third heat exchange channel 113, the engine cooling system bypasses the first heat exchange channel 111, the air-conditioning refrigeration system bypasses the second heat exchange channel 112, and the battery cooling system is connected in series with the third heat exchange channel 113. Through two heat exchanges between first heat transfer passageway, second heat transfer passageway and the third heat transfer passageway, can realize that engine cooling system heats for battery cooling system to and air conditioner refrigerating system cools off for engine cooling system and battery cooling system respectively.
In the present embodiment, the engine cooling system includes an engine 1 and a radiator 2 connected in series. The water outlet pipeline of the engine is also bypassed with the water inlet of the one-way valve 3, the water outlet of the one-way valve 3 is connected with one end of the first heat exchange channel 111, and the other end of the first heat exchange channel 111 is connected with the water inlet of the engine.
In this embodiment, the air-conditioning refrigeration system includes a compressor 4, a condenser 5, an expansion valve 6, and an evaporator 8, which are connected in series in this order. The outlet of the condenser 5 is also connected with the inlet of a proportional three-way valve 7, and two outlets of the proportional three-way valve 7 are respectively connected with the second heat exchange channel 112 and the inlet of the evaporator 8. A fan 12 is also included, the fan 12 being arranged alongside the radiator 2 and the condenser 5.

The control process of the automobile cooling control system is as follows:
when the battery temperature is lower than the lowest working temperature of the battery, the proportional three-way valve is not communicated with the evaporator, is communicated with the second heat exchange channel and is communicated with the one-way valve, and the battery temperature is too low to be heated at the moment, so that part of the engine coolant exchanges heat with the third heat exchange channel through the first heat exchange channel and heats the battery to the temperature higher than the lowest working temperature of the battery.
When the temperature of the battery is higher than or equal to the lowest working temperature of the battery, the proportional three-way valve is communicated with the evaporator and the second heat exchange channel respectively, and then the working states of the one-way valve and the proportional three-way valve are controlled through the water temperature of the engine and the wind speed of the fan.
When the water temperature of the engine is lower than the critical water temperature or/and the fan air speed is lower than the maximum air speed, the engine is not in the limit working condition, the one-way valve is disconnected at the moment, the flow ratio of the flow of the proportional three-way valve to the evaporator and the second heat exchange channel is adjusted, the air-conditioning refrigeration system cools the passenger compartment and the battery at the same time, and the temperature of the battery is kept between the lowest working temperature and the highest working temperature.
When the water temperature of the engine is greater than or equal to the critical water temperature and the wind speed of the fan is greater than or equal to the maximum wind speed, the engine is in the limit working condition, at the moment, if the temperature of the battery is less than the maximum working temperature of the battery, the one-way valve is communicated, and the air-conditioning refrigeration system cools the battery and the engine coolant at the same time; if the temperature of the battery is higher than or equal to the highest working temperature of the battery, the one-way valve is disconnected, the air-conditioning refrigeration system preferentially cools the battery, after the temperature of the battery is lower than the highest working temperature of the battery, the one-way valve is opened and simultaneously cools the cooling liquid of the engine, and at the moment, the proportion of the proportional three-way valve is controlled according to the cooling requirements of the battery and the engine.
