[0052] The electric vehicle arranges the power battery on the chassis, which can vacate space in the front of the vehicle body as a front trunk. At present, the utilization rate of the front trunk is relatively low.

[0053] To solve the above technical problems, the embodiments of the present application provide a vehicle front trunk, a vehicle thermal management system and a vehicle. The vehicle front trunk, the vehicle thermal management system and the vehicle provided by the embodiments of the present application will be introduced in detail below with reference to the accompanying drawings of the specification.

[0054] See Figure 1, A vehicle provided by an embodiment of the present application includes a motor (not shown in the figure), a power battery (not shown in the figure) electrically connected to the motor, and a vehicle thermal management system 1. This vehicle is an electric vehicle powered by a power battery and driven by a motor, including but not limited to a pure electric vehicle and a hybrid electric vehicle. Since the heat generated by an electric vehicle is mainly concentrated in the battery and the motor, during the driving process of the electric vehicle, the stator core and stator winding of the motor will generate losses during movement, and these losses are dissipated outward in the form of heat. During the charging and discharging process, the chemical substances in the power battery will undergo complex chemical reactions and also generate a large amount of heat during use. The vehicle thermal management system 1 is mainly used for cooling and temperature control, and can adjust the cooling intensity according to the driving conditions and environmental conditions to ensure that the cooled objects such as the motor and the power battery work in the optimal temperature range, thereby optimizing the environmental protection performance and energy-saving effect of the whole vehicle.

[0055] See Figure 1 , The vehicle thermal management system 1 includes a motor cooling circuit 200 and a battery cooling circuit 300. The motor cooling circuit 200 includes a motor cooling pipe 201 and a radiator 202 connected to each other; the battery cooling circuit 300 includes a battery cooling pipe 301 and a refrigeration circuit 310, and the refrigeration circuit 310 includes an evaporator 311, and the evaporator 311 is connected to the battery cooling pipe 301. Among them, the motor cooling pipe 201 is arranged on the motor, and the battery cooling pipe 301 is arranged on the power battery. For a power battery with a large surface area, the battery cooling pipe 301 can be laid flat on the surface of the power battery.

[0056] The vehicle thermal management system 1 further includes a water supply component (not shown in the figure), and the water supply component is used to supply circulating coolant to the motor cooling circuit 200 and the battery cooling circuit 300. In some embodiments, for the motor cooling circuit 200 and the battery cooling circuit 300 that are interconnected, only one set of water supply components may be provided. This water supply component includes a water tank and a water pump, which can meet the supply of coolant in the motor cooling circuit 200 and the battery cooling circuit 300. In other embodiments, for the motor cooling circuit 200 and the battery cooling circuit 300 that are independent of each other, separate water supply components need to be provided separately to supply coolant to the motor cooling circuit 200 and the battery cooling circuit 300 respectively. The water supply component may include a first water supply component and a second water supply component; the first water supply component includes a first water tank and a first pump, the liquid outlet of the first pump is connected to the liquid inlet end of the motor cooling pipe 201, and the liquid outlet of the radiator 202 is connected to the first water tank; the second water supply component includes a second water tank and a second pump, the liquid outlet of the second pump is connected to the liquid inlet end of the evaporator 311, and the liquid outlet of the battery cooling pipe 301 is connected to the second water tank. Among them, see Figure 1The vehicle thermal management system 1 shown can make the motor cooling circuit 200 communicate with or be independent of the battery cooling circuit 300 through the third control valve 317 and the fourth control valve 318.

[0057] Since a large amount of heat is generated when the motor is working, and a large amount of heat is also generated when the power battery is charging and discharging, the coolant will be heated after passing through the motor cooling pipe 201, and the coolant will also be heated after passing through the battery cooling pipe 301. Therefore, the vehicle thermal management system 1 dissipates and cools the coolant heated by the motor cooling pipe 201 through the radiator 202 of the motor cooling circuit 200, and exchanges heat and cools the coolant heated by the battery cooling pipe 301 through the evaporator 311 of the battery cooling circuit 300.

[0058] Considering the effective utilization of the energy generated during the operation of the electric vehicle, as well as improving the utilization rate of the front trunk and meeting the user's need to store items with special environmental temperature requirements, refer to Figure 1 and Figure 2 , the vehicle thermal management system 1 of the embodiment of the present application further includes a vehicle front trunk. The vehicle front trunk includes a box body 100, and the box body 100 has an independent first accommodation cavity 110 and a second accommodation cavity 120; a heating pipeline 111 is provided on the cavity wall of the first accommodation cavity 110; a cooling pipeline 121 is provided on the cavity wall of the second accommodation cavity 120. The heating pipeline 111 can be connected to the motor cooling circuit 200, and the coolant is connected to the heating pipeline 111 after being heated by the motor cooling pipe 201, and the waste heat of the motor can be used to heat the first accommodation cavity 110; the cooling pipeline 121 can be connected to the battery cooling circuit 300. The coolant is connected to the cooling pipeline 121 after heat exchange and cooling by the evaporator 311, and the cold of the evaporator 311 can be used to cool the second accommodation cavity 120.

[0059] The solution provided by the embodiment of the present application heats the first accommodation cavity 110 through the heating pipeline 111 on the cavity wall of the first accommodation cavity 110 and cools the first accommodation cavity 110 through the cooling pipeline 121 on the cavity wall of the second accommodation cavity 120, so that the first accommodation cavity 110 and the second accommodation cavity 120 are suitable for storing items with special environmental temperature requirements, such as cold drinks that need to be frozen in a high-temperature environment in summer, fresh flowers that need to be stored at a constant temperature in a low-temperature environment in winter, etc., effectively meeting the user's need to store items with special environmental temperature requirements, and thus improving the utilization rate of the front trunk.

[0060] In some embodiments, the box body 100 may include a plurality of side plates 101 and partition plates 102. The plurality of side plates 101 enclose to form a sealed space. Among them, at least one side plate 101 can move relative to the other side plates 101, so as to open or close the sealed space. The partition plate 102 is arranged in the sealed space to divide the sealed space into a first accommodation cavity 110 and a second accommodation cavity 120. The heating pipeline 111 is provided on the part of the side plate 101 that constitutes the first accommodation cavity 110, and the cooling pipeline 121 is provided on the part of the side plate 101 that constitutes the second accommodation cavity 120. Exemplarily, referring to Figure 2 , the box body 100 may be a hexahedron structure formed by enclosing six side plates 101. Among them, five side plates 101 form the bottom wall and four side walls of the box body 100, and the remaining one side plate 101 can be used as the cover plate of the box body 100. The cover plate can be movably connected to the side wall by means of rotation, telescoping, etc. to realize the opening and closing of the box body 100. It can be understood that the box body 100 can also be a sphere, an ellipsoid, other polyhedrons or various irregular storage structures. Designers can flexibly design according to actual needs and customer personalized requirements, and the present application does not make specific limitations in this regard. There are various ways to arrange the heating pipeline 111 or the cooling pipeline 121 on the side plate 101. In one possible implementation manner, the heating pipeline 111 or the cooling pipeline 121 can be pre-buried inside the side plate 101, and at least one of the methods of spiral winding, parallel winding, circular winding, and cross winding can be used for laying. In another possible implementation manner, the heating pipeline 111 or the cooling pipeline 121 can be formed on the side plate 101 while manufacturing the side plate 101. For example, when the side plate 101 is injection molded, a special mold is used to directly form the required heating pipeline 111 or cooling pipeline 121 on the side plate 101.

[0061] In some embodiments, the outer surface of the side plate 101 is wrapped with a thermal insulation layer (not shown in the figure) and / or a vacuum insulation layer is provided inside the partition plate 102 (not shown in the figure). The thermal insulation layer can be wrapped only on the outer surface of the side plate 101, or the vacuum insulation layer can be provided only inside the partition plate 102, or the thermal insulation layer can be wrapped on the outer surface of the side plate 101 and the vacuum insulation layer can be provided inside the partition plate 102 at the same time. It can be understood that by wrapping the thermal insulation layer on the outer surface of the side plate 101, the functions of heat preservation and heat insulation can be achieved, the heat preservation and heat insulation performance of the box body 100 can be improved, and the energy consumption can be reduced. There are many types of materials for the thermal insulation layer. For example, polyethylene foam board, polyurethane foam board, foamed ceramic thermal insulation material, etc. can be used. Designers can flexibly select according to various factors such as heat insulation performance, fire resistance, durability, environmental protection, and cost. The embodiments of the present application do not make specific limitations in this regard. The vacuum insulation layer provided inside the partition plate 102 can reduce the heat transfer in the forms of conduction, convection, and radiation between the first accommodation cavity 110 and the second accommodation cavity 120, and effectively improve the heat insulation performance. The shape of the vacuum insulation layer is similar to that of the partition plate 102, and the thickness of the vacuum insulation layer can be set according to the thickness of the partition plate 102. On the premise of ensuring the structural strength of the partition plate 102, in order to obtain better heat insulation performance, the thickness of the vacuum insulation layer should be increased as much as possible.

[0062] See Figure 1 , in some embodiments, the refrigeration circuit 310 further includes a compressor 312, a condenser 313, and an electronic expansion valve 314. The compressor 312, the condenser 313, the electronic expansion valve 314, and the evaporator 311 are connected in series in sequence; wherein, the condenser 313 is configured with a cooling fan 315.

[0063] Among them, the high-temperature and high-pressure gaseous refrigerant compressed by the compressor 312 enters the condenser 313 through the refrigeration circuit 310 for heat dissipation. The refrigerant changes from high-temperature and high-pressure gaseous to medium-temperature and high-pressure liquid during heat dissipation in the condenser 313. By blowing the condenser 313 with the cooling fan 315, the heat can be transferred to the outside air to achieve effective heat dissipation. The liquid refrigerant enters the evaporator 311 after being depressurized by the electronic expansion valve 314. The depressurized refrigerant becomes a low-temperature and low-pressure gas-liquid mixture and absorbs heat and vaporizes in the evaporator 311, taking away the heat of the coolant heated by the power battery, thereby realizing the refrigeration of the coolant of the power battery. The cooled coolant is connected to the cooling pipeline 121 to realize the cooling of the second accommodation cavity 120.

[0064] See Figure 1 and Figure 2, the liquid inlet end of the heating pipeline 111 can be connected to the liquid outlet of the motor cooling pipe 201, and the liquid outlet end of the heating pipeline 111 can be connected to the liquid inlet of the radiator 202; wherein, the coolant enters the heating pipeline 111 after being heated by the motor cooling pipe 201, and the heating of the first accommodating cavity 110 can be realized. After that, the coolant returns to the water supply component after being cooled by the radiator 202, and the heating process is repeated in a cycle. The liquid inlet end of the cooling pipeline 121 is connected to the liquid outlet of the radiator 202, and the liquid outlet end of the cooling pipeline 121 is connected to the liquid inlet of the battery cooling pipe 301. Among them, after being cooled by the evaporator 311, a part of the coolant can enter the cooling pipeline 121, cool the power battery through the battery cooling coil after cooling the first accommodating cavity 110, and another part of the coolant can directly cool the power battery through the battery cooling coil. Finally, the coolant returns to the water supply component, and the cooling process is repeated in a cycle.

[0065] See Figure 1 , in some embodiments, the vehicle thermal management system 1 may further include a first control valve 203, a second control valve 302, a first temperature sensor 204, a second temperature sensor 303, and a controller; the first control valve 203 is arranged between the heating pipeline 111 and the motor cooling pipe 201; the second control valve 302 is arranged between the cooling pipeline 121 and the radiator 202; the first temperature sensor 204 is arranged at the liquid outlet of the motor cooling pipe 201; the second temperature sensor 303 is arranged at the liquid outlet of the battery cooling pipe 301; the controller is electrically connected to the first control valve 203, the second control valve 302, the first temperature sensor 204, and the second temperature sensor 303.

[0066] The controller can control the working states of the heating pipeline 111 and the cooling pipeline 121 through the first control valve 203, the second control valve 302, the first temperature sensor 204, and the second temperature sensor 303 to realize functions such as heating, refrigeration, and heat preservation. On the one hand, the controller can control the opening and closing of the first control valve 203 or adjust the opening degree of the first control valve 203 according to the coolant temperature detected by the first temperature sensor 204 at the liquid outlet of the motor cooling pipe 201. On the other hand, the controller can also control the opening and closing of the second control valve 302 or adjust the opening degree of the second control valve 302 according to the coolant temperature detected by the second temperature sensor 303 at the liquid inlet of the battery cooling pipe 301.

[0067] Since the electrochemical reactions at the interfaces of the electrodes or electrolytes of the power battery are related to the ambient temperature, considering that when the ambient temperature is low, the reaction rate of the electrodes decreases, resulting in a reduction in the discharge current and power output of the power battery. In some embodiments, the vehicle thermal management system 1 further includes a battery heating circuit 400. The battery heating circuit 400 is connected to the battery cooling circuit 300 through an electronically controlled four-way valve 316, and is used to heat the coolant flowing through the battery cooling pipe 301, thereby adjusting the temperature of the power battery, ensuring that the power battery operates within the optimal working temperature range, increasing the driving range of the vehicle in cold environments, and reducing the impact of low temperature on the performance and lifespan of the power battery.

[0068] Among them, the controller is electrically connected to the compressor 312 and the electronically controlled four-way valve 316. When the ambient temperature is high and the power battery needs to be cooled, the electronically controlled four-way valve 316 can be controlled by the controller to cut off the battery heating circuit 400, and the compressor 312 can be controlled to operate to achieve the cooling of the power battery. When the ambient temperature is low and the power battery needs to be heated, the compressor 312 can be turned off by the controller, and the electronically controlled four-way valve 316 can be controlled to connect the battery heating circuit 400, so that the battery heating circuit 400 heats the power battery.

[0069] See Figure 1 , the battery heating circuit 400 may include a connected third water tank 401, a third water pump 402, and an electric heating element 403; the third water pump 402 is used to drive the coolant in the third water tank 401 to flow. The electric heating element 403 generates heat through electrothermal conversion for heating, and usually uses a positive temperature coefficient thermistor (Positive Temperature Coefficient, PTC), so it can also be directly called PTC. According to the characteristics of the heating medium, the electric heating element 403 can be divided into an air heater (APTC) and a water heater (WPTC). In the embodiments of the present application, a water heater can be used. The water heater is installed outside the vehicle's air conditioning box and is used to heat the coolant. The heated coolant flows through the battery cooling coil to transfer heat to the power battery to achieve the heating of the power battery.
