When the hybrid vehicle uses the above thermal management system, because the hybrid vehicle includes the first integrated system and the controller, the air conditioning heating module 100 of the first integrated system is provided with the main heating circuit 110, the electric heating control branch 120 and the first heat exchange control branch 130 are arranged in parallel and connected into the main heating circuit 110, and the first heat exchange control branch 130 is connected into the first heat exchange channel, the electric driving heat dissipation module 200 is connected into the second heat exchange channel, that is, the electric driving heat dissipation module 200 can exchange heat with the first heat exchange control branch 130 through the first heat exchanger 300, and meanwhile, the controller is respectively connected with the electric heater 111 on the main heating circuit 110, the first control valve 121 on the electric heating control branch 120 and the second control valve 131 on the first heat exchange control branch 130 in a communication manner, so that under the condition that the air conditioning heating instruction is received, the real-time heat exchange temperature of the first heat exchanger 300 is determined first, and under the condition that the real-time heat exchange temperature of the first heat exchanger 300 exceeds the first temperature threshold value, then the second control valve 111 and the first control valve 131 are controlled to be turned on and turned off, and the electric heating system is switched on, thereby the heat dissipation is fully reduced with the electric heating module 130, and the heat exchange is fully controlled by the electric heater control valve 130, and the electric heating module is switched to the main heating circuit 130, and the heat consumption is fully controlled. Meanwhile, the switching control is performed only under the condition that the real-time heat exchange temperature of the first heat exchanger 300 exceeds the first temperature threshold, so that the reliability of heating can be ensured.

Specifically, the electric heater 111 for electrically heating the heating liquid is connected to the warm air heating main circuit 110 of the air conditioning heating module 100, the first circulation pump 112 and the warm air core 113 in the air conditioning heating system are connected to the air conditioning heating main circuit, and the blower 114 for blowing the warm air core 113 is also arranged in the vehicle air conditioner, so that the heating liquid heated by the electric heater 111 or subjected to heat exchange with the electric dissipating heat module 200 is led to the warm air core 113, and hot air is blown out from the driving space by the blower 114. It should be noted that, whether the electric heater 111 is used for heating or the electric dissipating heat module 200 is used for heating, the blower 114 is controlled to be turned on, and specifically: upon receiving the air conditioning heat command, the blower 114 is controlled to be turned on and the real-time heat exchange temperature of the first heat exchanger 300 is detected. In addition, the air conditioner heating command may be sent through a button or a screen button of the driving space, and after detecting the real-time heat exchange temperature of the first heat exchanger 300 in case of receiving the air conditioner heating command, the method may further include: in case the real-time heat exchange temperature of the first heat exchanger 300 does not exceed the first temperature threshold, the electric heater 111 and the first control valve 121 are controlled to be turned on and the second control valve 131 is controlled to be turned off to realize air-conditioning heat by heating of the electric heater 111.

Referring to fig. 2 to 4, in the embodiment of the present invention, the air conditioning and heating module 100 includes a first circulation pump 112, an electric heater 111, a warm air core 113, and a blower 114, where the first circulation pump 112, the electric heater 111, and the warm air core 113 are sequentially disposed on the warm air and heating main path 110, the first circulation pump 112 is used for pumping the heating liquid on the electric heating control branch 120 or the first heat exchange control branch 130 to the warm air core 113, the blower 114 is used for blowing air to the warm air core 113, the first heat exchange channel is disposed between the second control valve 131 and the first circulation pump 112, and the first heat exchange control branch 130 is provided with a first temperature sensor 132 that is in communication connection with the controller and can detect the real-time heat exchange temperature of the first heat exchanger 300. The first heat exchange channel is arranged between the second control valve 131 and the first circulating pump 112 instead of between the warm air core 113 and the second control valve 131, so that the temperature of heating liquid in the first heat exchange channel is only affected by heat exchange, the control accuracy is ensured, and in addition, the first temperature sensor 132 is arranged on the newly added first heat exchange control branch 130 instead of the heat dissipation circulation loop 210 of the electric drive heat dissipation module 200, on one hand, the transformation point can be reduced as much as possible, and on the other hand, the influence of the change of the heat exchange efficiency can be avoided.

Further, when the heating liquid is heated by the electric heater 111, the circulation path is as follows: the first circulating pump 112-the electric heater 111-the warm air core 113-the first control valve 121-the first circulating pump 112; when the heating liquid adopts a circulation path for heat exchange with the electric dissipation heat module 200 to heat, the circulation path is as follows: the first circulation pump 112-the electric heater 111-the warm air core 113-the second control valve 131-the first heat exchange channel-the first circulation pump 112. Still further, the heating liquid may be water or other suitable liquid, the electric heater 111 may be a PTC (Positive Temperature Coefficient, thermistor) heater, and the air-conditioning heating module 100 further includes a first liquid replenishment tank 115 for filling the warm air heating main circuit 110 with the heating liquid.

As shown in fig. 1,2 and 6, in the embodiment of the present invention, the first integrated system further includes an engine heat dissipating device 400, the engine heat dissipating device 400 includes a first heat dissipating liquid outlet pipe 410, a first heat dissipating liquid return pipe 420 and a third control valve 430, the first heat dissipating liquid outlet pipe 410 and the first heat dissipating liquid return pipe 420 are respectively connected to the liquid inlet end and the liquid outlet end of the warm air core 113 in a one-to-one correspondence manner, and the third control valve 430 is disposed on the first heat dissipating liquid return pipe 420 and is communicatively connected to the controller, and the controller is further configured to:

under the condition of receiving the air conditioning heat command, acquiring the liquid outlet temperature of heat dissipation of the engine;

in the case where the outlet temperature of the engine heat radiation exceeds the second temperature threshold, the third control valve 430 is controlled to be turned on and the electric heater 111, the first control valve 121, and the second control valve 131 are controlled to be turned off.

Specifically, under the condition that the air conditioning heat command is received, the temperature of the heat emitted by the engine can be obtained first, and the temperature data of the heat emitted by the engine can be obtained through bus control detection, and under the condition that the real-time heat exchange temperature of the first heat exchanger 300 exceeds the second temperature threshold, then the third control valve 430 is controlled to be opened and the electric heater 111, the first control valve 121 and the third control valve 430 are closed, so that the electric heating main circuit 110 is disconnected from the electric heating control branch circuit 120 and the first heat exchange control branch circuit 130, and the air conditioning heat source is from the waste heat of the engine heat radiator 400, thereby fully utilizing the waste heat of the engine to heat the driving space, reducing the loss of battery electric quantity and improving the endurance mileage of the whole vehicle. Meanwhile, switching control is performed only under the condition that the liquid outlet temperature of the heat dissipation of the engine exceeds a second temperature threshold, so that the reliability of heating can be ensured.

More specifically, when heating is performed using engine waste heat, the first circulation pump 112 does not need to participate in the operation, and may be controlled to be turned off, and the circulation path is: first heat dissipation drain pipe 410-warm air core 113-third control valve 430-first heat dissipation return pipe 420. And the second temperature threshold value can be larger than, equal to or smaller than the first temperature threshold value, and the values of the second temperature threshold value and the first temperature threshold value are determined according to actual conditions.

In an embodiment of the invention, the controller is further configured to:

Under the condition of receiving the air conditioning heat command, acquiring the liquid outlet temperature of heat dissipation of the engine and detecting the real-time heat exchange temperature of the first heat exchanger 300;

In the case that the real-time heat exchange temperature of the first heat exchanger 300 does not exceed the first temperature threshold and the outlet temperature of the engine heat radiation does not exceed the second temperature threshold, the electric heater 111 and the first control valve 121 are controlled to be turned on and the second control valve 131 and the third control valve 430 are controlled to be turned off.

Specifically, under the condition that the air conditioning heat command is received, the real-time heat exchange temperature of the engine heat dissipation liquid outlet temperature and the real-time heat exchange temperature of the first heat exchanger 300 can be determined at the same time, then the real-time heat exchange temperature of the first heat exchanger 300 is compared with the first temperature threshold value, and the real-time heat exchange temperature of the engine heat dissipation liquid outlet temperature and the second temperature threshold value are compared, if the real-time heat exchange temperature of the first heat exchanger 300 and the engine heat dissipation liquid outlet temperature do not exceed the corresponding temperature threshold values, it can be determined that the air conditioning heat cannot be met by both the electric drive waste heat and the engine waste heat, at the moment, the second control valve 131 and the third control valve 430 can be controlled to be closed so as to cut off the supply of the electric drive waste heat and the engine waste heat to the warm air core 113, and simultaneously the electric heater 111 and the first control valve 121 are controlled to be opened so as to switch to supply heat to the warm air core 113 in an electric heating mode, and the reliability of the air conditioning heat is ensured.

In particular, when the hybrid vehicle runs in the pure electric mode, only the real-time heat exchange temperature of the first heat exchanger 300 may be detected when the air-conditioning heat command is received; when the hybrid power vehicle runs in a pure fuel mode and receives the air conditioning heat command, only the liquid outlet temperature of the heat dissipation of the engine can be obtained; when the hybrid vehicle runs in the hybrid mode, the air conditioning heat command is received, the real-time heat exchange temperature of the first heat exchanger 300 needs to be detected as well as the liquid outlet temperature of the engine heat dissipation, and when the real-time heat exchange temperature of the first heat exchanger 300 exceeds the first temperature threshold and the liquid outlet temperature of the engine heat dissipation exceeds the second temperature threshold, the third control valve 430 can be controlled to be opened and the electric heater 111, the first control valve 121 and the second control valve 131 can be closed, because the electric drive waste heat is relatively small, and the engine waste heat can be used.

Referring to fig. 2,4 and 5, in the embodiment of the present invention, a second temperature sensor 122 is further provided on the electric heating control branch 120, and the second temperature sensor 122 is communicatively connected to the controller and is used for detecting the real-time heating temperature of the electric heating control branch 120, and when the real-time heat exchange temperature of the first heat exchanger 300 does not exceed the first temperature threshold and the outlet temperature of the engine heat dissipation does not exceed the second temperature threshold, the method further includes, after controlling to open the electric heater 111 and the first control valve 121 and closing the second control valve 131 and the third control valve 430:

Acquiring a real-time heating temperature;

The heating power of the electric heater 111 is adjusted according to the difference of the real-time heating temperature and the preset heating temperature of the air conditioner in the driving space.

Further, after the heating power of the electric heater 111 is turned on, the difference between the real-time heating temperature (T ₂) detected by the second temperature sensor 122 and the preset heating temperature (T _{Thermal device} ) of the air conditioner in the driving space can be linearly adjusted, and the calculation formula of the difference Δt is as follows: Δt=t ₂-T _{Thermal device} , and the larger Δt, the smaller the heating power of the electric heater 111, and when Δt is less than or equal to 0, the heating power of the electric heater 111 is the maximum value.

As can be seen from the above, when the air conditioner in the driving space needs to heat, the blower 114 is controlled to turn on the heating air core 113, the first circulation pump 112 is turned on, and when the real-time heat exchange temperature detected by the first temperature sensor 132 does not exceed the first temperature threshold and the liquid temperature of the engine heat dissipation does not exceed the second temperature threshold, the electric heater 111 and the first control valve 121 are controlled to be turned on and the second control valve 131 and the third control valve 430 are controlled to be turned off, so as to perform air-conditioning heating in an electric heating manner, and the heating power of the electric heater 111 is linearly adjusted by the difference between the real-time heating temperature detected by the second temperature sensor 122 and the preset heating temperature of the air conditioner in the driving space, wherein the larger Δt is, the smaller the heating power of the electric heater 111 is; when the real-time heat exchange temperature detected by the first temperature sensor 132 exceeds the first temperature threshold, the electric heater 111 and the first control valve 121 are controlled to be closed, the second control valve 131 is controlled to be opened, the electric drive waste heat is utilized by the first heat exchanger 300, and the air conditioning heat is carried out by the electric drive waste heat; when the temperature of the discharged liquid of the engine heat radiation does not exceed the second temperature threshold, the first control valve 121, the second control valve 131 and the electric heater 111 are controlled to be closed, and the third control valve 430 is controlled to be opened, so that the air conditioning heat is performed by using the engine waste heat.

In the embodiment of the present invention, the air conditioning and refrigerating module 500 includes a compressor 511, a condenser 512 and an evaporator 522, where the compressor 511 and the condenser 512 are disposed on the compression and condensation main path 510, the evaporator 522 is disposed on the evaporation control branch 520 and is located at the rear end of the fourth control valve 521, the evaporator 522 shares the blower 114 with the warm air core 113, and when the real-time heat exchange temperature of the second heat exchanger 700 exceeds the third temperature threshold, the control unit further includes, after turning on the compressor 511 on the compression and condensation main path 510:

Upon receiving the air conditioning cooling command, control opens the fourth control valve 521 and the blower 114.

In an embodiment of the present invention, the controller is further configured to:

When the air conditioning cooling command is received and the real-time heat exchange temperature of the second heat exchanger 700 is greater than the third temperature threshold, the fourth control valve 521 and the blower 114 are controlled to be turned on and the output power of the compressor 511 is adjusted to the maximum required power, wherein the maximum required power is set to be the larger one of the air conditioning cooling required power and the battery heat dissipation required power.

Specifically, when the air conditioning refrigeration and the battery heat dissipation in the driving space depend on the operation of the compressor 511, the output power of the compressor 511 is adjusted to a larger value of the two required powers, so that excessive power consumption loss is avoided.

Referring to fig. 8 and 9, in an embodiment of the present invention, the air conditioning and refrigerating module 500 further includes a first cooling fan 515 for blowing air to the condenser 512, and a main path sensor 514 communicatively connected to the controller and used for detecting the system pressure or temperature is further disposed on the compression and condensation main path 510, and the controller is further configured to:

In an embodiment of the invention, the controller is further configured to:

in case that the real-time detected temperature of the evaporator 522 is lower than the minimum threshold value of the preset temperature range of the evaporator 522, the control closes the fourth control valve 521 and reduces the output power of the compressor 511.

It will be appreciated that the cooling capacity in the riding space can be reduced by the control method described above, avoiding frosting of the evaporator 522. After this step, if it is detected that the real-time detected temperature of the evaporator 522 is higher than the maximum threshold value of the preset temperature range of the evaporator 522, it is possible to control the fourth control valve 521 and the blower 114 to be turned on and to restore the output power of the compressor 511.

As can be seen from the above, when the battery system has a heat dissipation and cooling requirement, the third circulating pump 630 is preferably turned on to perform natural cooling, when the third circulating pump 630 cannot meet the heat dissipation and cooling requirement of the battery system, that is, when the real-time heat exchange temperature detected by the third temperature sensor 531 exceeds the third temperature threshold, the compressor 511 is controlled to be turned on, if there is no air-conditioning and cooling requirement, the fourth control valve 521 is kept closed, the compressor 511 is turned on to heat up and boost the refrigerant, and cool the refrigerant through the condenser 512, and then performs heat exchange with the battery waste heat through the second heat exchanger 700, so as to take away the heat of the battery water path, perform heat dissipation on the battery system, and when the pressure on the compression and condensation main circuit 510 rises to the system threshold, the first cooling fan 515 is controlled to perform water heating on the condenser 512 to perform cooling and depressurization on the refrigerant.

When the air conditioner in the driving space has a refrigerating requirement, the blower 114 and the fourth control valve 521 are controlled to be started, the compressor 511 starts to work, the temperature and the pressure of the refrigerant are increased, the temperature of the front end of the evaporator 522 is reduced, and the driving space is refrigerated; when the pressure on the compression condensation main path 510 rises to the system threshold value, the first cooling fan 515 is controlled to be started to cool the condenser 512 so as to cool and decompress the refrigerant; in case that the temperature sensor of the evaporator 522 detects that the real-time detected temperature is lower than the minimum threshold value of the preset temperature range of the evaporator 522, the fourth control valve 521 is closed, and simultaneously the output power of the compressor 511 is reduced, so that the cooling beam of the riding space is reduced, and the frosting of the surface of the evaporator 522 is avoided.

When the air conditioner and the battery system in the driving space have simultaneous cooling demands, the compressor 511, the fourth control valve 521, the blower 114 and the first cooling fan 515 are simultaneously turned on, and the output power of the compressor 511 is adjusted to the maximum demand power, and the rotation speed of the first cooling fan 515 is adjusted to the maximum demand rotation speed, wherein the maximum demand power is set to take the larger one of the air conditioner cooling demand power and the battery cooling demand power, and the maximum demand rotation speed is set to take the larger one of the air conditioner cooling demand rotation speed and the battery cooling demand rotation speed. If there is a conflict between the cooling requirement of the air conditioner in the driving space and the heat dissipation and cooling requirement of the battery system, for example, the amount of the refrigerant is insufficient, the heat dissipation and cooling requirement of the battery system is controlled preferentially, specifically, the blower 114 and the fourth control valve 521 are controlled to be closed.
