Background
The turbo charging is a technology of driving an air compressor by using exhaust gas generated by the operation of an internal combustion engine, and in the process of pressurizing air, the temperature of compressed air is greatly increased due to heat transfer of the exhaust gas and air density increase, so that in order to reduce the temperature of the compressed air, the density of the air entering the engine is increased, and an intercooler is required to cool the pressurized air and then send the cooled air into the engine.

In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
Fig. 1 is a schematic structural diagram of an automotive thermal management system according to an embodiment of the present application. The automobile thermal management system 10 shown in fig. 1 includes: radiator 101, three-way solenoid valve 102, first three-way pipe 103, first integrated motor 104, second integrated motor 105, charging and distributing device 106, first water pump 107, second water pump 108 and car battery 109, four-way reversing valve 110, temperature sensor 111, water-cooling intercooler 113, third water pump 114 and second three-way pipe 115. Optionally, a cooling device 112 and a third tee 116 may also be included. Wherein, as shown in the figure:
the radiator 101, the three-way electromagnetic valve 102, the first three-way pipe 103, the first integrated motor 104, the second integrated motor 105, the charging and distributing device 106, the first water pump 107, the four-way reversing valve 110, the temperature sensor 111, the second three-way pipe 115, the third three-way pipe 116 and the radiator 101 are sequentially connected in sequence to form a first loop.
The second water pump 108, the automobile battery 109, the four-way reversing valve 110, the cooling device 112 and the second water pump 108 are sequentially connected to form a second loop.
In an alternative embodiment, one end of the first tee 103, the water-cooled intercooler 113, the third water pump 114, and the second tee 115 are sequentially connected to form a parallel branch, so that the water-cooled intercooler 113 and the third water pump 114 in the parallel branch are connected in parallel to the first circuit. Alternatively, the three-way electromagnetic valve 102 is connected to the third three-way pipe 116 and connected to the first loop, so as to achieve shorting of the radiator 101.
In practical applications, the system may control the on-off of the ports of the three-way electromagnetic valve 102 and the four-way reversing valve 110, so that the first loop and the second loop operate in series or independently, thereby realizing the switching operation between the three modes of cooling the water-cooled intercooler 113, not cooling the water-cooled intercooler 113 and heating the automobile battery 109.
The water-cooling intercooler 113 has an air inlet, an air outlet, a liquid inlet and a liquid outlet. The liquid inlet is connected into the first loop through the second water pump 108 and the second tee pipe 115, and the liquid outlet is connected into the first loop through the first tee pipe 103. The air inlet and the air outlet are both used for communicating the air inlet of the engine after turbocharging.
Several modes of operation/operation of the automotive thermal management system according to the present application are described below.
In a specific embodiment, the system may control the second port 2 and the third port 3 of the three-way solenoid valve 102 to communicate, control the second port 2 and the fourth port 4 of the four-way steering valve to communicate, and control the first port 1 and the third port 3 to communicate, wherein the first circuit and the second circuit operate independently of each other, and the first circuit is used for cooling devices on the first circuit, that is, cooling electric drive related components, when the vehicle engine is not turned on, the water-cooled intercooler 113 has no cooling requirement, and the second water pump 108 is not operated (or neither the water-cooled intercooler nor the second water pump is operated). The second circuit is used to cool the car battery 109.
In yet another embodiment, the vehicle is in a hybrid mode, specifically when the engine of the vehicle is turned on, the water-cooled intercooler 113 has a cooling requirement (for example, the temperature of the cooling liquid in the water-cooled intercooler exceeds a first preset temperature, etc.), and the second water pump 108 is working normally, in which case the system may control the second port 2 and the third port 3 of the three-way electromagnetic valve 102 to communicate, control the second port 2 and the fourth port 4 of the four-way steering valve to communicate, control the first port 1 and the third port 3 to communicate, and control the parallel branch to connect and work in the first circuit, and the first circuit and the second circuit operate independently of each other. In this case, the working temperature of the cooling liquid in the water-cooled intercooler 113 is similar to the working temperature of the cooling liquid in the electric driving part, and the simultaneous cooling of the electric driving part and the water-cooled intercooler 113 is realized.
In yet another embodiment, the vehicle is in a residual heat mode, and in particular, in a low temperature environment (e.g., the ambient temperature is lower than a second preset temperature), the vehicle battery 109 is in need of heating, and the water-cooled intercooler 113 is operated with a large amount of heat released in the coolant. In specific implementation, the automobile engine is turned on, the water-cooled intercooler 113 has a cooling requirement, the second water pump 108 works normally, the system can control the first end 1 and the second end 2 of the three-way electromagnetic valve 102 to be communicated, the radiator 101 is in short circuit, the first port 1 and the second port 2 of the four-way steering valve are controlled to be communicated, the third port 3 and the fourth port 4 of the four-way steering valve are controlled to be communicated, the first loop and the second loop are operated in series, and therefore the waste heat of the water-cooled intercooler 113 is used for heating the automobile battery 109 so as to fully utilize a heat source and reduce energy consumption required for heating the automobile battery.
In practical applications, the system may also collect the temperature of the cooling liquid collected by the temperature sensor 111 at regular time according to the actual requirement, so as to switch the corresponding mode/working operation condition according to the temperature of the cooling liquid. Specifically, when the automobile is started in a low-temperature environment, the system of the application can control the first end 1 and the second end 2 of the three-way electromagnetic valve 102 to be communicated, the radiator 101 is short-circuited, so as to prevent heat in the cooling liquid from being dissipated into the air through the radiator 101, and the temperature sensor 111 detects the temperature of the cooling liquid in the pipeline (simply referred to as cooling liquid temperature). After the temperature of the cooling liquid reaches the first threshold, the first port 1 and the second port 2 of the four-way steering valve 110 are controlled to be communicated, the third port 3 and the fourth port 4 are controlled to be communicated, and the first loop and the second loop are operated in series for rapidly heating the automobile battery 109.
When the temperature of the automobile battery 109 reaches a second threshold value, the second port 2 and the fourth port 4 of the four-way steering valve are controlled to be communicated, and the first port 1 and the third port 3 are controlled to be communicated, so that the first loop and the second loop run independently of each other, and the battery temperature is prevented from being heated too high and damage to the battery is avoided.
When the temperature of the automobile battery 109 drops to a third threshold (i.e., below the third threshold), the present application may control the first port 1 and the second port 2 of the four-way diverter valve to be in communication, and the third port 3 and the fourth port 4 to be in communication, at which time the first circuit and the second circuit are operated in series again to heat the automobile battery 109 by using the residual heat of the water-cooled intercooler 113.
It should be noted that, the first threshold, the second threshold and the third threshold related to the present application are all set by the system in a self-defined manner, and the present application is not limited thereto.
