Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way. In addition, in the description of the embodiments of the present invention, unless otherwise specified, the meaning of "multiple" refers to two or more.

[0046] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0047] It should be understood that, although the terms first, second, third, etc. may be used to describe various thresholds, signals, and instructions in the embodiments of the present invention, these thresholds, signals, and instructions should not be limited to these terms. These terms are only used to distinguish thresholds, signals, and instructions from each other. For example, without departing from the scope of the embodiments of the present invention, the first threshold may also be referred to as the second threshold, and similarly, the second threshold may also be referred to as the first threshold, etc.

[0048] In addition, the term “and / or” in the present invention means that it can be any one of them or two of them at the same time.

[0049] The storage structure provided by the utility model is introduced in detail below:

[0050] The present invention takes into account that the cooling system of the prior art is usually integrated in the engine compartment. In view of this integrated design, when the vehicle needs to be cooled, the entire cooling system needs to be fully started and operated, which results in the phenomenon that the heat dissipation efficiency is not fully utilized, leading to unnecessary waste of heat dissipation resources.

[0051] Therefore, the present invention conceives that a vehicle cooling system and a vehicle can be designed, wherein the vehicle cooling system is divided into two subsystems, and the independent circulation and combined circulation of each cooling subsystem are controlled by a connecting structure, so that not only can the two sub-cooling systems independently dissipate heat for the vehicle, so that the two sub-cooling systems can be selectively enabled, but they can also be merged into one to dissipate heat for the vehicle.

[0052] Based on the above utility model concept, the utility model embodiment provides a vehicle cooling system, such as Figure 1 shown.

[0053] The vehicle cooling system of the present invention comprises: a first cooling subsystem 10 , a second cooling subsystem 20 and a connecting structure 30 .

[0054] Specifically, the connection structure 30 is configured to control at least one of the self-circulation state of the first cooling subsystem 10 , the self-circulation state of the second cooling subsystem 20 , and the combined circulation state of the first cooling subsystem 10 and the second cooling subsystem 20 .

[0055] The vehicle cooling system and vehicle provided by the utility model divide the vehicle cooling system into two parts, namely, a first cooling subsystem 10 and a second cooling subsystem 20. The independent circulation and the combined circulation of each cooling subsystem are controlled by a connecting structure 30, which not only enables the two sub-cooling systems to dissipate heat for the vehicle separately, so that the two sub-cooling systems can be selectively enabled, but also enables them to be combined into one to dissipate heat for the vehicle. In this way, through the coordination of multiple heat dissipation methods, while ensuring the overall heat dissipation capacity of the system and meeting the various heat dissipation requirements of the vehicle, the heat dissipation power consumption of the entire cooling system is also reduced. In addition, they can also be set at different positions of the vehicle based on actual application requirements, which increases the flexibility of the position setting of the vehicle cooling system.

[0056] Furthermore, the first cooling subsystem 10 is arranged in the front cabin of the vehicle; the second cooling subsystem 20 is arranged in the rear cabin of the vehicle. In this way, by arranging a part of the vehicle cooling system (i.e., the first cooling subsystem 10) in the front cabin and the other part (i.e., the second cooling subsystem) in the rear cabin, the size of the cooling system arranged in the engine compartment can be reduced, and the requirements for the heat exchange performance of the cooling system can be reduced; it can also avoid the problem of increased exhaust back pressure caused by the unchanged cabin layout space, thereby increasing the air intake volume of the cooling system arranged in the engine compartment, and further improving the heat dissipation capacity of the entire cooling system.

[0057] Based on the above, the vehicle cooling system is divided into two parts, namely the first cooling subsystem 10 and the second cooling subsystem 20. The first cooling subsystem 10 is arranged in the front cabin of the vehicle, and the second cooling subsystem 20 is arranged in the rear cabin of the vehicle which is not affected by heat damage. In this way, arranging a part of the vehicle cooling system in the rear cabin not only reduces the size of the first cooling subsystem 10 and reduces the required heat exchange performance; it can also reduce the exhaust back pressure under the same layout space of the front cabin, thereby increasing the air intake volume of the first cooling subsystem 10 and improving the heat dissipation capacity of the entire first cooling subsystem 10.

[0058] In some embodiments, the connection structure 30 includes at least four interfaces, at least two of which are used to connect to the inlet and outlet of the first cooling subsystem 10 respectively, and at least two of which are used to connect to the inlet and outlet of the second cooling subsystem 20 respectively.

[0059] In some embodiments, reference Figure 2a The connection structure 30 includes a first three-way valve 121 and a second three-way valve 211. The inlet 121a of the first three-way valve 121 is connected to the outlet of the first cooling subsystem 10, the first outlet 121b of the first three-way valve 121 is connected to the inlet of the second cooling subsystem 20, and the second outlet 121b of the first three-way valve 121 is connected to the inlet of the first cooling subsystem 10; the inlet 211a of the second three-way valve 211 is connected to the outlet of the second cooling subsystem 20, the first outlet 211b of the second three-way valve 211 is connected to the inlet of the first cooling subsystem 10, and the second outlet 211c of the second three-way valve 211 is connected to the inlet of the second cooling subsystem 20.

[0060] Optionally, both the first three-way valve 121 and the second three-way valve 211 may be electromagnetic three-way valves.

[0061] In a possible implementation, the three-way valve (i.e., the first three-way valve 121 or the second three-way valve 211) includes three branches and a rotatable annular channel, the angle between any branches is 120°, and the annular channel is connected to any two branches after rotation, and the outer ends of the three branches respectively constitute the inlet of the three-way valve, the first outlet of the three-way valve, and the second outlet of the three-way valve. Different conduction states of the first three-way valve 121 and the second three-way valve 211 can realize different circulation modes of the coolant.

[0062] It can be understood that the inlet 121a of the first three-way valve 121, the second outlet 121b of the first three-way valve 121, and the first outlet 211b of the second three-way valve 211 are three interfaces of the connection structure 30 for respectively communicating with the inlet and outlet of the first cooling subsystem 10. The first outlet 121b of the first three-way valve 121, the inlet 211a of the second three-way valve 211, and the second outlet 211c of the second three-way valve 211 are three interfaces of the connection structure 30 for respectively communicating with the inlet and outlet of the second cooling subsystem 20.

[0063] In one implementation, when the second outlet 121b of the first three-way valve 121 is in an on state and the first outlet of the second three-way valve is in an on state, the first cooling subsystem 10 and the second cooling subsystem 20 are in a combined cycle state; and / or,

[0064] When the first outlet 121b of the first three-way valve 121 is in an on state and the second outlet 121b of the first three-way valve 121 is in a closed state, the first cooling subsystem 10 is in a self-circulating state; and / or,

[0065] When the first outlet of the second three-way valve is in a closed state, the second outlet of the second three-way valve is in a conducting state, and the second cooling subsystem 20 is in a self-circulating state.

[0066] In some more specific embodiments, the inlet 121a of the first three-way valve 121 and the second outlet 121c of the first three-way valve 121 are connected through the annular channel to achieve Figure 2b The first cooling subsystem 10 shown in FIG. 1 is independently activated (ie, the first cooling subsystem 10 is in a self-circulating state). The inlet 211a of the second three-way valve 211 and the second outlet 211c of the second three-way valve 211 are connected through the annular channel to achieve Figure 2c The second cooling subsystem 20 is shown to be independently activated (ie, the second cooling subsystem 20 is in a self-circulating state).

[0067] In another embodiment, the inlet 121a of the first three-way valve 121 and the first outlet 121b of the first three-way valve 121 are connected through an annular channel, and the inlet 211a of the second three-way valve 211 and the first outlet 211b of the second three-way valve 211 are connected through an annular channel, so that Figure 2d As shown, the first cooling subsystem 10 and the second cooling subsystem 20 are activated as a whole (ie, the first cooling subsystem 10 and the second cooling subsystem 20 are in a combined cycle state).

[0068] In some embodiments, the first three-way valve 121 is used to control the opening and closing of the first cooling subsystem 10 and the connection state between the first cooling subsystem 10 and the first inlet 212 b of the second communicating vessel 212 .

[0069] The second three-way valve 211 is used to control the opening and closing of the second cooling subsystem 20 and the connection state between the second cooling subsystem 20 and the first inlet 111 c of the first communicating vessel 111 .

[0070] Optionally, the first three-way valve 121 is configured to be able to switch the connection state between the first outlet 121b of the first three-way valve 121 and the first inlet 212b of the second communicating vessel 212 , and to switch the connection state between the second outlet 121c of the first three-way valve 121 and the second inlet 111b of the first communicating vessel 111 .

[0071] The second three-way valve 211 is configured to switch the connection between the first outlet 211b of the second three-way valve 211 and the first inlet 111c of the first manifold 111 , and to switch the connection between the second outlet 211c of the second three-way valve 211 and the second inlet 212a of the second manifold 212 .

[0072] In another possible implementation, referring to Figure 3The three-way valve can also be replaced by a one-way valve. Therefore, the connecting structure 30 includes a first one-way valve 301 and a second one-way valve 302. The inlet of the first one-way valve 301 is connected to the outlet of the first cooling subsystem 10, and the outlet of the first one-way valve 301 is connected to the inlet of the second cooling subsystem 20; the inlet of the second one-way valve is connected to the outlet of the second cooling subsystem 20, and the outlet of the second one-way valve 302 is connected to the inlet of the first cooling subsystem 10.

[0073] It can be understood that the inlet of the first one-way valve 301 and the outlet of the second one-way valve are two interfaces of the connection structure 30 for respectively communicating with the inlet and outlet of the first cooling subsystem 10. The outlet of the first one-way valve 301 and the inlet of the second one-way valve 302 are two interfaces of the connection structure 30 for respectively communicating with the inlet and outlet of the second cooling subsystem 20.

[0074] In some embodiments, when the first one-way valve 301 and the second one-way valve 302 are both in the on state, the first cooling subsystem 10 and the second cooling subsystem 20 are in the combined circulation state, and the first cooling subsystem 10 and the second cooling subsystem 20 are both in the self-circulation state.

[0075] When the first one-way valve 301 and the second one-way valve 302 are both in a closed state, the first cooling subsystem 10 and the second cooling subsystem 20 are both in a self-circulating state.

[0076] In other embodiments, the connection structure 30 also includes a third one-way valve 303 and a fourth one-way valve 304; the third one-way valve 303 is connected between the inlet of the first cooling subsystem 10 and the outlet of the first cooling subsystem 10; the fourth one-way valve 304 is connected between the inlet of the second cooling subsystem 20 and the outlet of the first cooling subsystem 10.

[0077] It can be understood that, based on the first one-way valve 301 and the second one-way valve 302, the inlet and outlet of the third one-way valve 303 are two other interfaces of the connection structure 30 for respectively communicating with the inlet and outlet of the first cooling subsystem 10. The inlet and outlet of the fourth one-way valve 304 are two other interfaces of the connection structure 30 for respectively communicating with the inlet and outlet of the second cooling subsystem 20.

[0078] When the first one-way valve 301 and the second one-way valve 302 are both in the on state, the first cooling subsystem 10 and the second cooling subsystem 20 are in the combined circulation state; and / or, when the third one-way valve 303 is in the on state, the first cooling subsystem 10 is in the self-circulation state; and / or, when the fourth one-way valve 304 is in the on state, the first cooling subsystem 10 is in the self-circulation state.

[0079] In some embodiments, reference Figure 5The first cooling subsystem 10 includes a low-temperature cooling circuit 11, a high-temperature cooling circuit 12, and a condenser 122; the low-temperature cooling circuit 11 and the high-temperature cooling circuit 12 circulate independently, and the condenser 122 is arranged at the front cabin air inlet 13 of the vehicle, and the condenser 122 is used for external heat exchange of the air conditioning system.

[0080] In a specific embodiment, the condenser 122 is located at the front cabin air inlet 13 of the vehicle, that is, behind the air intake grille of the front cabin. The air intake temperature is a lower external ambient temperature, the refrigeration efficiency is greatly improved, and the energy consumption of the compressor is greatly reduced.

[0081] In some embodiments, since the utility model divides the low-temperature cooling into two parts, which are respectively located in the front cabin of the engine 126 and the rear cabin of the vehicle, it can not only make the cooling system set in the rear cabin not be affected by the heat damage of the cabin, but also enhance the heat exchange capacity of the device; it can also reduce the size of the low-temperature cooling part in the front cabin, which reduces the size of the low-temperature radiator in the low-temperature cooling circuit 11 in the first cooling subsystem 10, so that the low-temperature radiator and the condenser 122 can be arranged in parallel at the front cabin air inlet 13, thereby improving the heat exchange efficiency of the low-temperature radiator. Therefore, the low-temperature cooling circuit 11 includes a first low-temperature radiator 119, and the high-temperature cooling circuit 12 includes a high-temperature radiator 123; the first low-temperature radiator 119 and the condenser 122 are arranged in parallel at the front cabin air inlet 13 of the vehicle, and the high-temperature radiator 123 is arranged on the side of the first low-temperature radiator and the condenser 122 away from the front cabin air inlet 13.

[0082] The high temperature cooling circuit 12 is used to exchange heat with the engine 126 so as to cool the engine 126. When the low temperature cooling circuit 11 is in independent circulation, it is mainly used to exchange heat with the water-cooled intercooler 113 included in the first branch 11b, and the oil-cooled plate 115 and the first electronic control system 114 included in the second branch 11c.

[0083] In one of the embodiments, the first low-temperature radiator 119 and the condenser 122 are located at the front cabin air inlet 13 of the vehicle, that is, behind the air intake grille, and can exchange heat with the outside by itself. For example, the first low-temperature radiator 119 is located behind the air intake grille. When the vehicle is running, the airflow enters the air intake grille and flows through the first low-temperature radiator 119 to exchange heat with it. In a specific embodiment, the first low-temperature radiator 119 is smaller in size than the low-temperature radiator integrally arranged in the prior art, and is arranged behind the air intake grille on the left side of the vehicle without a separate fan. During the cooling process, the water side of the first low-temperature radiator 119 is connected to exchange heat with the outside world. Its heat exchange performance is affected by wind speed and wind temperature. The wind speed of the first low-temperature radiator 119 is related to the vehicle speed and the air intake grille opening parameters, and the wind temperature is basically consistent with the ambient temperature.

With the goal of balancing the flow of the two branches, the modules in the first branch 11b and the second branch 11c are adjusted based on the flow resistance of the modules that require the low-temperature cooling circuit 11 to dissipate heat. For example, the three modules of the water-cooled intercooler 113, the oil-cooled plate exchanger 115 and the first electronic control system 114 can be randomly adjusted in the first branch 11b and the second branch 11c according to actual applications. Of course, when a new module that requires the low-temperature cooling circuit 11 to dissipate heat is added to the vehicle, it can also be added to the first branch 11b and the second branch 11c. In particular, other branches that are connected in parallel with the first branch 11b and the second branch 11c can also be added.

[0096] It should be noted that the upstream of the second three-way valve 211 refers to the upstream direction of the valve installation position, that is, the side where the fluid enters the valve (that is, the inlet 211a of the second three-way valve 211). In a fluid system, the fluid enters the valve from the upstream direction through the pipeline, and then flows out from the downstream direction of the valve (that is, the first outlet 211b of the second three-way valve 211 or the second outlet 211c of the second three-way valve 211) through the control and regulation of the valve.

[0100] It should be noted that the communicating vessel involved in the present application may be a three-way communicating vessel, that is, the communicating vessel includes three communicating ports, the three communicating ports including an inlet and an outlet. In practical applications, the outlet and the inlet of the three communicating ports are determined according to the flow direction of the liquid.

[0101] In a possible implementation, the second cooling subsystem 20 further includes a rear cabin air inlet passage 219 , and an air outlet of the rear cabin air inlet passage 219 faces the second low-temperature radiator 214 .

[0102] Optional, see Figure 6The second cooling subsystem 20 also includes a second fan 218. The second fan 218 can be arranged on a side of the second low-temperature radiator 214 away from the rear cabin air inlet channel 219, or can be arranged on other sides of the second low-temperature radiator 214. The present invention does not impose any limitation on this.

[0103] In order to better understand the connectivity logic of the present utility model, based on Figure 6 The single circulation implementation of the first cooling subsystem 10 includes the circulation of the low-temperature cooling circuit 11 and the circulation of the high-temperature cooling circuit 12 .

[0104] The circulation mode of the low-temperature cooling circuit 11 includes: the outlet of the first low-temperature radiator 119 is connected to the first inlet of the first three-way valve 121. In particular, a first temperature sensor is installed between the outlet of the first low-temperature radiator 119 and the first inlet of the first three-way valve 121. The first temperature sensor is used to collect the outlet temperature of the first low-temperature radiator 119. The second outlet 121c of the first three-way valve 121 is connected to the second inlet 111b of the first communicating vessel 111. The outlet of the first communicating vessel 111 is connected to the inlet 112a of the third communicating vessel 112. The first outlet 112c and the second outlet of the third communicating vessel 112 are connected to the first branch 11b and the second branch 11c respectively. The first outlet 112c of the third communicating vessel 112 is connected to the inlet of the water-cooled intercooler 113 in the first branch 11b. The outlet of the water-cooled intercooler 113 is connected to the a port of the fourth communicating vessel 116. The second outlet 112a of the third communicating vessel 112 is connected to the inlet of the first electric control system 114 in the second branch 11c. The outlet of the control system 114 is connected to the inlet of the oil cooling plate exchanger 115, the outlet of the oil cooling plate exchanger 115 is connected to the second inlet 116c of the fourth communicating vessel 116, the outlet 116b of the fourth communicating vessel 116 is connected to the first inlet 117a of the fifth communicating vessel 117, the second inlet 117b of the fifth communicating vessel 117 is connected to the first water tank 129, the first water tank 129 is used to replenish the coolant to the low-temperature cooling circuit 11 through the second inlet 117b of the fifth communicating vessel 117, the outlet 117c of the fifth communicating vessel 117 is connected to the inlet of the first water pump 118, and the outlet of the first water pump 118 is connected to the inlet of the first low-temperature radiator 119, thereby forming a circulation loop. That is, the low-temperature cooling circuit 11.

[0105] In particular, to ensure the independent circulation of the low-temperature cooling circuit 11, the first outlet 121b of the first three-way valve 121 is closed, the second outlet 121c of the first three-way valve 121 and the inlet 121a of the first three-way valve 121 are both opened, and the first water pump 118 is turned on.

[0106] Furthermore, the circulation of the high-temperature cooling circuit 12 includes: the outlet of the engine 126 is connected to the inlet of the high-temperature radiator 123, the inlet of the engine 126 is connected to the outlet of the second water pump 125, the inlet of the second water pump 125 is connected to the outlet 124a of the sixth communicating vessel 124, the first inlet 124c of the sixth communicating vessel 124 is connected to the outlet of the high-temperature radiator 123, the outlet of the second water tank 128 is connected to the second inlet of the sixth communicating vessel, and the second water tank 128 is used to replenish coolant to the high-temperature cooling circuit 12 through the second inlet 124b of the sixth communicating vessel 124.

[0107] The second cooling subsystem 20 is enabled separately in the following way: the outlet of the second low-temperature radiator 214 is connected to the inlet of the vehicle power supply 215, the outlet of the vehicle power supply 215 is connected to the inlet of the rear three-in-one 216, and the outlet of the rear three-in-one 216 is connected to the inlet of the second electromagnetic three-way valve. In particular, a first temperature sensor is also provided between the outlet of the rear three-in-one 216 and the inlet of the second electromagnetic three-way valve, and the first temperature sensor is used to collect the temperature at the outlet of the rear three-in-one 216, the second outlet of the second electromagnetic three-way valve is connected to the second inlet 212a of the second communicating vessel 212, the outlet 212c of the second communicating vessel 212 is connected to the inlet of the third water pump 213, and the outlet of the third water pump 213 is connected to the inlet of the second low-temperature radiator 214 to form a circulation loop.

[0108] In particular, to ensure normal independent circulation of the second cooling subsystem 20, the third water pump 213 works, the first inlet of the second three-way valve 211 is closed, and the outlet of the second three-way valve 211 and the second inlet of the second three-way valve 211 are opened.

[0109] It can be understood that the first cooling subsystem 10 and the second cooling subsystem 20 are integrated into one, that is, it can be achieved by integrating the low-temperature cooling circuit 11 in the first cooling subsystem 10 and the second cooling subsystem 20 into one.

[0110] The low-temperature cooling circuit 11 in the first cooling subsystem 10 and the second cooling subsystem 20 are combined into one circulation mode by changing the switch state of each valve port in the first three-way valve 121 and the second three-way valve 211 in the structure of the first cooling subsystem 10 and the second cooling subsystem 20. Specifically, the inlet 121a of the first three-way valve 121 and the first outlet 121b of the first three-way valve 121 are opened, and the second outlet 121c of the first three-way valve 121 is closed; and the inlet 211a of the second three-way valve 211 and the first outlet 211b of the second three-way valve 211 are opened, and the second outlet 211c of the second three-way valve 211 is closed, and the first water pump 118 and the third water pump 213 are controlled to work, so that the low-temperature cooling circuit 11 and the second cooling subsystem 20 can be combined into one circulation loop.

[0111] Based on the above, when the vehicle is in AC charging, it is determined whether to start the independent circulation of the first cooling subsystem 10 according to the cooling demand of the vehicle power supply 215. If so, the temperature of the vehicle power supply 215 detected by the second temperature sensor is used to control the operation of the second fan 218, and continue to determine whether the battery has a cooling request. If so, the first cooling subsystem 10 and the second cooling subsystem 20 are combined into an integrated circulation. In this way, the energy consumption can be reduced as much as possible while meeting the cooling demand.

[0112] When the vehicle is in a non-AC charging condition and the vehicle is in an OK state (which can refer to a startup state or a driving state), the load demand of the vehicle cooling system is judged by the temperature detected by the first temperature sensor. When the load demand is a small load (such as the first temperature sensor value < t1, t1 is a calibration threshold), the first cooling subsystem 10 circulates independently; when the load demand is a medium load (such as t1≤the first temperature sensor value < t2, t2 is a calibration threshold, and t2>t1), the first cooling subsystem 10 and the second cooling subsystem 20 are combined into an integrated cycle, and the first water pump 118 and the second fan 218 are controlled by the second temperature sensor to control the electric drive cooling, the electric control cooling or the intake temperature of the engine 126; when the load demand is a large load (such as t2≤the first temperature sensor value), the temperatures detected by the second temperature sensor and the first temperature sensor are used to coordinately control the operation of the first fan 127 to control the electric drive temperature, the electric control temperature and the intake temperature of the engine 126 within a reasonable range. This control method dynamically adjusts the cooling method according to the different cooling loads required by the vehicle, thereby achieving precise control of the temperature within a reasonable range while reducing the energy consumption of the entire vehicle.

[0113] In another possible implementation, the vehicle cooling system provided by the utility model can also perform heat recovery, that is, one sub-cooling system can recover heat from another sub-cooling system. For example, when the second cooling subsystem needs heat to heat the vehicle's cockpit, the first cooling subsystem can be used to perform heat exchange with the engine heat and / or battery heat in the front cabin, and the collected heat can be transferred to the second cooling subsystem.

[0114] In another embodiment of the present invention, a vehicle is provided, comprising the above-mentioned vehicle cooling system.

[0115] The above description is only a preferred embodiment of the utility model and an explanation of the technical principles used. Those skilled in the art should understand that the disclosure scope involved in the utility model is not limited to the technical solution formed by a specific combination of the above technical features, but also should cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the aforementioned disclosure concept. For example, the above features are replaced with the technical features with similar functions disclosed in the utility model (but not limited to) to form a technical solution.
