The first aspect of the application provides a vehicle thermal management system 10, the vehicle thermal management system 10 being a thermal management system of a new energy vehicle capable of using electric energy as a driving energy source to enable driving of the vehicle by a driving motor.

FIG. 1 is a schematic block diagram of a vehicle thermal management system 10 according to an embodiment of the present application.

Referring to fig. 1, a vehicle thermal management system 10 includes an electric drive assembly 11, the electric drive assembly 11 being configured to provide driving force to a vehicle such that the vehicle is driven by the electric drive assembly 11. In some application scenarios, the electric drive assembly 11 may be divided into a front drive assembly for driving front wheels of a vehicle and a rear drive assembly for driving rear wheels of the vehicle, where the vehicle is a four-drive type vehicle.

The vehicle thermal management system 10 further includes an electric dissipating heat circuit that includes a closed circuit in end-to-end communication in which a coolant can circulate to achieve thermal circulation through the coolant to achieve heat dissipation. Wherein, part of the electric heat dissipation loop is arranged in the electric drive assembly 11, that is, part of the pipelines in the electric heat dissipation loop are positioned in the electric drive assembly 11, so that the electric heat dissipation loop dissipates heat to the electric drive assembly 11 through circulating cooling liquid. At this time, a heat exchanger (not shown) may be disposed in the electric drive assembly 11, and a portion of the electric heat dissipation loop located in the electric drive assembly 11 may be a part of the heat exchanger, so as to exchange heat with the electric drive assembly 11 through the heat exchanger.

The vehicle thermal management system 10 further includes a low temperature radiator 12, the low temperature radiator 12 being disposed in the electric heat dissipating circuit, the low temperature radiator 12 being configured to dissipate heat from the coolant. At this time, the low-temperature radiator 12 may be regarded as a part of an electric heat dissipation circuit in which a pipe passes through the low-temperature radiator 12 to achieve heat dissipation of the coolant by the low-temperature radiator 12.

It should be understood that the low-temperature radiator 12 is a radiator that exchanges heat with the cooling liquid through air, and is disposed at the front end of the vehicle, so as to dissipate heat of the low-temperature radiator 12 through air intake of the front end air inlet of the vehicle. It should be understood that the flow direction of the air inlet flow formed by the front air inlet is the direction from the head to the tail.

Further, the vehicle thermal management system 10 further includes a water-cooled intercooler 13 and an intercooler 14, and the water-cooled intercooler 13 and the intercooler 14 are connected in series in the intercooler branch. The water-cooling intercooler 13 and the intercooler 14 are heat exchangers, and the intercooler branch includes a pipeline for circulating cooling liquid, and a part of the pipeline is located in the water-cooling intercooler 13 and a part of the pipeline is located in the intercooler 14. At this time, the water-cooled intercooler 13 and the intercooler radiator 14 may be regarded as a part of the intercooler branch.

At this time, the water-cooled intercooler 13 is used for radiating heat of the charge air, that is, the coolant in the pipeline of the water-cooled intercooler 13 exchanges heat with the charge air, so as to radiate heat of the charge air. The intercooler 14 is used for dissipating heat of the cooling liquid in the intercooler branch, that is, the cooling liquid in the pipeline of the intercooler 14 exchanges heat with air, so as to dissipate heat of the cooling liquid in the pipeline.

In combination with the above, the intercooler branch is connected in parallel with the portion of the electric dissipating heat loop located in the electric driving assembly 11, that is, the pipeline in the intercooler branch is connected in parallel with the heat dissipating pipeline in the electric dissipating heat loop. Based on the communication mode, the cooling liquid led out from the low-temperature radiator 12 can be respectively led in, and the cooling liquid led in the intercooling radiating branch and the cooling liquid led out from the intercooling radiating branch sequentially pass through the intercooling radiator 14 and the water-cooling intercooler 13 at the part of the intercooling radiating branch and the electric radiating loop, which is positioned in the electric drive assembly 11.

It should be understood that the temperature of the cooling liquid led out from the low-temperature radiator 12 is low, and the cooling liquid led out from the low-temperature radiator 12 is led into the middle cooling branch and the electric drive assembly 11 respectively to realize heat dissipation of the water cooling middle cooling device 13 and the electric drive assembly 11. In this case, the water-cooled intercooler 13 requires a lower temperature of the coolant than the electric drive assembly 11 when heat dissipation is performed. Since the coolant introduced into the intercooler branch and the electric drive assembly 11 are both led out from the low-temperature radiator 12, the temperatures of the coolant introduced into the intercooler branch and the electric drive assembly 11 are the same. Through the setting of intercooler 14 for the coolant liquid has carried out the cooling of certain degree before leading into water-cooling intercooler 13, and then reduces the temperature of the coolant liquid in entering water-cooling intercooler 13, and then satisfies the demand of water-cooling intercooler 13 to the lower temperature of coolant liquid. The temperature of the cooling liquid after heat dissipation of the water-cooling intercooler 13 and the electric drive assembly 11 is increased, the cooling liquid after the temperature increase enters the low-temperature radiator 12 for cooling, and then the cooled cooling liquid is led out of the low-temperature radiator 12, so that circulation is realized.

In summary, through the above arrangement, the electric dissipation heat loop can simultaneously realize the heat dissipation of the water-cooling intercooler 13 and the electric driving assembly 11, and through the low-temperature radiator 12, the heat dissipation of the water-cooling intercooler 13 and the electric driving assembly 11 is realized, so that the cost of the whole vehicle is reduced. Moreover, through the setting of intercooler 14 for the temperature of the coolant liquid in entering water-cooling intercooler 13 can satisfy the demand, and then realize carrying out good heat dissipation to water-cooling intercooler 13.

Fig. 2 is a schematic layout view of a part of the structure of the vehicle thermal management system 10 according to an embodiment of the present application.

Referring to fig. 2, in some embodiments, the intercooler 14 and the low-temperature radiator 12 are arranged in layers in the longitudinal direction of the vehicle, and the intercooler 14 is disposed close to the vehicle head with respect to the low-temperature radiator 12 in the longitudinal direction of the vehicle.

It should be appreciated that, since the flow direction of the external heat radiation air flow is the direction from the head to the tail, the provision of the intercooler 14 before the low-temperature radiator 12 can ensure a good heat radiation effect of the intercooler 14. Also, the size of the intercooler 14 is generally small, and even if the intercooler 14 is provided before the low-temperature radiator 12, the heat dissipation of the low-temperature radiator 12 is not affected to a large extent.

With continued reference to fig. 2, in some embodiments, the vehicle thermal management system 10 further includes an air conditioning circuit having a condenser 21 disposed therein, the condenser 21 configured to dissipate heat from a refrigerant in the air conditioning circuit, the condenser 21 being co-located with the intercooler 14.

It should be appreciated that the air conditioning circuit and the electric dissipation heat circuit belong to different circuits in the vehicle thermal management system 10, and are not in communication. The condenser 21 and the intercooler 14 are arranged in the same layer, and the heat exchange with the external air flow is performed in the same way to perform heat exchange on the refrigerant in the air conditioning loop, thereby realizing the thermal cycle of the air conditioning system. By arranging the condenser 21 in front of the low-temperature radiator 12, a good heat radiation effect of the external air flow on the condenser 21 can be ensured, thereby ensuring that the air conditioning system works well.

With continued reference to fig. 2, in some embodiments, the intercooler 14 is positioned above the condenser 21 in the height direction of the vehicle, and the length of the intercooler 14 in the height direction of the vehicle is less than the length of the condenser 21 in the height direction of the vehicle.

Specifically, the intercooler 14 and the condenser 21 are equal in length in the width direction of the vehicle, and by the above arrangement, the size of the intercooler 14 is made smaller than the size of the condenser 21. It will be appreciated that the heat dissipation requirement of the intercooler 14 is lower than that of the condenser 21, and thus the heat dissipation requirements of the respective modules can be sufficiently ensured by the above-described dimensional arrangement. In addition, as the condenser 21 is arranged below the intercooler 14, and the air inlet of the heat dissipation air flow is arranged near the lower side, the heat dissipation air flow has good heat dissipation effect on the condenser 21, and the good working state of the air conditioning system is further ensured.

In other embodiments, to ensure good heat dissipation to the intercooler 14, the intercooler 14 may be disposed below the condenser 21, so that the heat dissipation airflow is directly blown to the intercooler 14 to ensure good heat dissipation effect to the intercooler 14.

For a specific arrangement of the intercooler 14, in some embodiments, the intercooler 14 includes a first intercooler and a second intercooler, the first intercooler is connected in series or parallel with the second intercooler, and the cooling liquid introduced into the intercooler branch is introduced into the water-cooled intercooler 13 through the first intercooler and the second intercooler, respectively.

The first intercooler and the second intercooler are the same type of radiator, and the first intercooler and the second intercooler are only used for distinguishing. It should be understood that, in a serial manner, the cooling fluid introduced into the intercooler branch may sequentially pass through the first intercooler and the second intercooler; for the parallel connection mode, the cooling liquid can simultaneously pass through the first intercooler radiator and the second intercooler radiator. Through setting up first intercooler radiator and second intercooler radiator, can be through selecting whether the work of first intercooler radiator and second intercooler radiator, adjust the intercooler radiator behavior, and then realize the adaptation to different scenes.

The engine cooling loop is used for cooling the engine, and the high-temperature radiator 22 in the engine cooling loop is used for cooling the cooling liquid, so that the cooling liquid can circulate in the engine cooling loop. Since the temperature of the high-temperature radiator 22 is high, the high-temperature radiator 22 can be arranged behind the low-temperature radiator 12, and then the high-temperature radiator 22 is radiated by the air flow passing through the low-temperature radiator 12, so that the most balanced radiating effect on each part is realized.

Fig. 4 is a block diagram of another embodiment of a vehicle thermal management system 10 provided by the present application.

In some embodiments, referring to fig. 4, a first valve body 16 is disposed in the electric heat dissipating circuit, the first valve body 16 being configured to control the flow of coolant into the intercooler branch and the flow of coolant into the portion of the electric heat dissipating circuit located within the electric drive assembly 11. It should be appreciated that the portion of the electric dissipating heat circuit that is located within the electric drive assembly 11, i.e., the portion of the circuit that is located within the electric drive assembly 11. At this time, the first valve body 16 can simultaneously control the flow rate of the cooling liquid entering the part of the intercooler branch and the electric heat dissipation circuit located in the electric drive assembly 11, so as to adjust the ratio between the cooling liquid entering the intercooler branch and the cooling liquid entering the part of the electric heat dissipation circuit located in the electric drive assembly 11.

Specifically, the first valve body 16 may be a three-way valve, which may selectively introduce the coolant into the intercooler branch or the electric drive assembly 11, and may selectively select the flow rate of the coolant into the intercooler branch, and may selectively select the flow rate of the coolant into the electric drive assembly 11. By the arrangement mode, the flow of the cooling liquid entering the water-cooling intercooler 13 and the electric drive assembly 11 can be regulated, and then the heat dissipation effect can be regulated.
