The integrated thermal management module 100 with the eight-way valve of the present invention includes at least the following functions:
the first mode is as follows: cabin heating
As shown in fig. 2, the integrated thermal management module 100 with the eight-way valve in mode one heats the cabin of the vehicle by means of the heat pump and the in-vehicle heater 7 as a supplemental heat source (which can be selectively turned on and off). In the mode, the interior evaporator 93 and the exterior radiator 4 are in the closed state.
The heat of the electric control unit 3 of the motor is taken away by the refrigerant after the heat and the refrigerant exchange heat through the first heat exchanger 2, after the supercharger 94 boosts the high-temperature and high-pressure refrigerant, the heat and the cooling liquid exchange heat through the second heat exchanger 5, the heat is used for heating the cabin in the vehicle through the cabin cooling liquid loop, and meanwhile, the vehicle inner heater 7 can be opened under the condition of needing rapid heating, and the effect of heating the cabin is further achieved. In this mode the battery 8 does not need to be thermally managed. The offboard heat exchanger 92 operates in an evaporator mode to absorb heat from the environment.
The first mode is a heat pump heating mode, and waste heat is recovered from the environment and the motor electronic control unit 3 to the maximum extent and is used for heating the cabin.
And a second mode: cabin heating, battery 8 heating
As shown in fig. 3, the second mode realizes the function of heating the battery 8 under the condition of heating the cabin, and ensures that the battery 8 can work under the proper working temperature condition (15-35 degrees). In the mode I, the cabin cooling liquid loop is connected with the battery 8 loop on the basis of the mode I, so that the heated cooling liquid passes through the battery 8 loop to achieve the effect of heating the battery 8 and completes loop circulation through the second heat exchanger 5. The heating of the cabin and the battery 8 can be realized through the second mode, so that the comfort of the vehicle can be realized under the lower-temperature environment condition, and meanwhile, the battery 8 is prevented from being damaged due to too low temperature under the appropriate temperature condition.
And a third mode: heating of the battery 8
As shown in fig. 4, the third mode is that the in-vehicle heater 7 heats the battery 8, and the application scenario is that when the ambient temperature is low, the vehicle is not started and the battery 8 is exposed to a lower temperature, for example, when the lifetime and the charge of the battery 8 are greatly influenced in an environment of ten degrees celsius or even below zero degrees celsius, the vehicle can keep the battery 8 at a reasonable temperature by the third mode.
And a fourth mode: residual heat heating battery 8 of electric control unit 3 of motor
As shown in fig. 5, the mode four is another implementation manner for keeping the temperature of or heating the battery 8, and the operating scenario is that the battery 8 is in a lower-temperature operating condition, and at this time, the motor electronic control unit 3 has a certain amount of heat due to its own heat generation characteristic, for example, when the vehicle is running in a low-temperature environment, the environmental temperature is lower, and at the same time, the battery 8 cannot operate in an appropriate temperature condition due to the air cooling effect, and at this time, the motor electronic control unit 3 has a higher temperature due to the long-time heat generation characteristic, and under this condition, the waste heat of the motor electronic control unit is kept and heated for the battery 8 by the connection manner, which has the advantage of ensuring the heat dissipation of the motor electronic control unit without increasing other energy consumption.
And a fifth mode: efficient heat dissipation of battery 8
As shown in fig. 6, under the fifth operating mode, the first heat exchanger 2 and the external radiator 92 are turned on, and under the fifth operating mode, in order to ensure that the battery 8 works under the appropriate temperature condition, the efficient heat dissipation effect of the battery 8 needs to be realized, and the application scenario is that the ambient temperature is higher than 45 degrees celsius, and the battery 8 needs to dissipate heat greatly. The system will realize through first heat exchanger 2 with battery 8 heat in first heat exchanger 2 department with the heat transfer of refrigerant after, take away the heat through the refrigerant to realize the heat exchange with the environment in vehicle exterior heat exchanger 92 department, thereby finally release the heat to realize the high-efficient radiating effect of battery 8 in the environment.
A sixth mode: ordinary heat dissipation of battery 8
As shown in fig. 7, the external heat sink 4 is turned on under six working conditions in the mode, the heat dissipation effect of the battery 8 of the vehicle is realized in the six mode, the working scene is the situation that the ambient temperature is lower than 45 degrees centigrade and the battery 8 needs to dissipate heat, and the realization method is that the battery 8 loop heat is released to the environment through the fan and the external heat sink 4 by connecting the battery 8 loop water path and the external heat sink 4 loop.
Mode seven: battery 8, heat dissipation of motor electric control unit 3 and air conditioner refrigeration
As shown in fig. 8, in mode seven, the second heat exchanger 5 is turned off with the in-vehicle heater and radiator turned off. And the seventh mode realizes the air conditioning refrigeration of the cabin in the vehicle and the heat dissipation effect of the battery 8 and the motor electric control unit 3. In the mode, the heat of the motor electric control unit 3 exchanges heat with the refrigerant through the first heat exchanger 2 to achieve the heat dissipation effect of the motor electric control unit 3; the battery 8 loop will release part of the heat of the battery 8 to the environment through the offboard radiator 4 to achieve the effect of dissipating the heat of the battery 8. The first heat exchanger 2 is configured to pressurize the refrigerant by the supercharger 94 to a high-temperature and high-pressure state, and to release heat to the environment by exchanging heat with the environment at the exterior heat exchanger 92 (operating in a condenser mode), and then to absorb heat of air blown out by the blower at the interior evaporator 93 (heat absorption) and finally blow cold air into the cabin, thereby achieving air conditioning and cooling effects.
And a eighth mode: heat dissipation of battery 8 and motor electric control unit 3
As shown in fig. 9, the radiator 4 outside the vehicle is opened, and the mode eight will realize the effect of radiating heat from the battery 8 and the motor electronic control unit 3 at the same time. The realization approach is that the battery 8 and the motor electronic control unit 3 release heat to the environment through the radiator 4 outside the vehicle, thereby realizing the radiating effect.
