[0032] Reference below Figure 1-Figure 5 A discharge device 100 according to an embodiment of the present invention is described.

[0033] According to the battery discharge device 100 for vehicles in the first embodiment of the utility model, a large amount of electricity is stored in the vehicle battery during the production or transportation of the vehicle, or when the vehicle needs to be returned to the factory for repair. The explosion of a fully charged battery after spontaneous combustion is more destructive, and reducing the amount of electricity stored in the vehicle battery can reduce the destructive power of spontaneous combustion of the vehicle battery and reduce the probability of explosion. Therefore, the discharge device 100 can be used to release the electricity in the vehicle battery.

[0034] The discharge device 100 includes an air conditioning assembly 10 and a first electrical connector 21, wherein the first electrical connector 21 is electrically connected to the air conditioning assembly 10, and the first electrical connector 21 is also suitable for being detachably connected to a vehicle battery so that the vehicle battery is electrically connected to the air conditioning assembly 10. When the discharge device 100 is required to discharge the vehicle battery, the first electrical connector 21 can be electrically connected to the vehicle battery so that the air conditioning assembly 10 consumes the power of the vehicle battery; when the discharge device 100 finishes discharging the vehicle battery, the first electrical connector 21 can be separated from the vehicle battery, for example, the first electrical connector 21 can be a discharge gun.

[0035] The air conditioning assembly 10 includes a condenser 11 and an evaporator 12, and the evaporator 12 is arranged adjacent to the condenser 11 for mutual heat exchange. When the first electrical connector 21 is electrically connected to the air conditioning assembly 10, the air conditioning assembly 10 is in working state, the condenser 11 releases heat, and the evaporator 12 can absorb heat, so that cooling and heating occur simultaneously and offset each other, and have no impact on the environment, and also enable the discharge device 100 to work for a long time; and the air conditioning assembly 10 consumes a large amount of power when it is in working state, and at the same time, the resistance generated when the refrigerant flows in the air conditioning assembly 10 increases the load of the air conditioning assembly 10, so that high-power electric energy consumption can be obtained, and the power stored in the vehicle battery can be quickly reduced or exhausted, thereby shortening the waiting time and improving the safety factor.

[0036] For example, the discharge device 100 may be installed in a vehicle, a dock, a process transportation transfer station, or a vehicle maintenance station.

[0037] In a specific example, the discharge device 100 further includes a control circuit board 27, and the control circuit board 27 is used to control the start or shut down of the air conditioning assembly 10. The air conditioning assembly 10 further includes a compressor 13 and a throttle valve, a first pipeline 15 is connected between the compressor 13 and the condenser 11, a second pipeline 16 is connected between the condenser 11 and the evaporator 12, and a third pipeline 17 is connected between the evaporator 12 and the compressor 13. The throttle valve is located on the second pipeline 16 and is used to control the pressure and flow rate of the refrigerant flowing from the condenser 11 to the evaporator 12.

[0038] When the power of the vehicle battery needs to be released, the first electrical connector 21 is electrically connected to the vehicle battery, and the control circuit board 27 can drive the air conditioning component 10 to work. When the air conditioning component 10 is working, the compressor 13 compresses the refrigerant in the compressor pipeline into high-temperature and high-pressure refrigerant hot steam; then it flows to the condenser 11 through the first pipeline 15, and the condenser 11 can reduce the temperature of the high-temperature and high-pressure refrigerant hot steam, and the high-temperature and high-pressure refrigerant hot steam becomes a refrigerant liquid, thereby releasing the heat of the refrigerant and increasing the temperature of the surrounding environment of the condenser 11; the refrigerant in the condenser 11 can flow to the evaporator 12 through the throttle valve in the second pipeline 16, and the evaporator 12 absorbs the surrounding heat to convert the liquid refrigerant into a gaseous refrigerant to reduce the temperature around the evaporator 12.

[0039] According to the discharge device 100 of the embodiment of the utility model, the first electrical connector 21 is used to connect the vehicle battery and the air conditioning component 10. The air conditioning component 10 includes a condenser 11 and an evaporator 12. The condenser 11 is used to release heat, and the evaporator 12 is used to absorb heat. The evaporator 12 is arranged adjacent to the condenser 11, which can improve the heat exchange efficiency of the condenser 11 and the evaporator 12. The heat absorption and heat dissipation occur simultaneously and offset each other, and have no impact on the environment, so that the discharge device 100 can work for a long time; and the power consumed by the discharge device 100 when working is large, which can improve the discharge efficiency of the vehicle battery.

[0040] According to some embodiments of the present invention, referring to Figure 4-Figure 5 The condenser 11 and the evaporator 12 are arranged in a first direction (for example, see the attached Figure 5 The projection areas of the condenser 11 and the evaporator 12 in the projection plane perpendicular to the first direction are both larger than the projection areas of the condenser 11 and the evaporator 12 in the projection plane perpendicular to the second direction (for example, see the attached Figure 5 and are larger than the projection area of ​​the condenser 11 and the evaporator 12 in the projection plane perpendicular to the third direction (for example, see the attached Figure 5 The projection area in the projection plane (in the direction indicated by e3 in the figure), that is, the projection area of ​​the condenser 11 and the evaporator 12 in the direction perpendicular to the first direction is the largest, and the condenser 11 and the evaporator 12 are spaced apart in the first direction, thereby improving the heat exchange efficiency of the condenser 11 and the evaporator 12. Among them, the first direction, the second direction and the third direction are perpendicular to each other.

[0041] According to some embodiments of the present invention, referring to Figure 4-Figure 5, the distance between the condenser 11 and the evaporator 12 in the first direction is d, satisfying: 18cm≤d≤22cm. For example, the distance between the condenser 11 and the evaporator 12 in the first direction may be 18cm, 19cm, 20cm, 21cm or 22cm. When the distance between the condenser 11 and the evaporator 12 in the first direction is within this range, the condenser 11 can absorb more cold released by the evaporator 12, and the evaporator 12 can also absorb more heat released by the condenser 11, so as to further improve the heat exchange efficiency between the condenser 11 and the evaporator 12.

[0042] According to some embodiments of the present invention, referring to Figure 4 The air conditioning assembly 10 further includes a fan 14 , which is located on a side of the condenser 11 away from the evaporator 12 . The fan 14 can provide air cooling for the condenser 11 , thereby allowing the condenser 11 to release more heat and improve the working efficiency of the condenser 11 .

[0043] According to some embodiments of the present invention, referring to Figure 1-Figure 5 , and also includes a housing 22, the housing 22 includes a bottom plate 223, the air conditioning assembly 10 is located in the housing 22, the housing 22 can provide an installation space for the air conditioning assembly 10, and can also be used to protect the air conditioning assembly 10, protecting the air conditioning assembly 10 from damage by the external environment. The air conditioning assembly 10 is fixed on the bottom plate 223, and during the transportation or handling of the discharge device 100, the air conditioning assembly 10 can be prevented from shaking, thereby improving the safety of the air conditioning assembly 10.

[0044] According to some embodiments of the present invention, referring to Figure 1-Figure 2 The discharge device 100 further includes a control panel 23, which is located on the housing 22. The control panel 23 is used to control the start or shut down of the air conditioning assembly 10. For example, the control panel 23 can be electrically connected to the control circuit board 27. When the vehicle battery needs to be discharged, the user can touch the control panel 23 to start the discharge device 100; when the vehicle battery is discharged, the user can touch the control panel 23 to shut down the discharge device 100, which can improve the convenience of using the discharge device 100.

[0045] According to some embodiments of the present invention, referring to Figure 1-Figure 3The shell 22 has an air inlet 24 and an air outlet 25. The air conditioning component 10 also includes a fan 14. The fan 14 is used to drive the air flow outside the shell 22 to enter the shell 22 through the air inlet 24 and then be discharged through the air outlet 25 after heat exchange with the air conditioning component 10. The fan 14 can increase the flow rate of the air flow in the shell 22; the air flow outside the shell 22 enters the shell 22 through the air inlet 24, and can cool the condenser 11. At the same time, the heat released by the condenser 11 can also be blown to the evaporator 12 to increase the temperature of the evaporator 12 and prevent the evaporator 12 from freezing.

[0046] According to some embodiments of the present invention, referring to Figure 1-Figure 3 The housing 22 includes a first wall plate 221 and a second wall plate 222 that are arranged at an angle. For example, the angle between the first wall plate 221 and the second wall plate 222 may be 90°. The first wall plate 221 has an air inlet 24, and the second wall plate 222 has an air outlet 25. The air inlet 24 and the air outlet 25 are respectively located on different wall plates of the housing 22. The airflow enters the housing 22 through the air inlet 24 and then exits the housing 22 through the air outlet 25. This can improve the fluidity of the airflow in the housing 22, and further improve the heat exchange efficiency between the airflow and the air conditioning assembly 10.

[0047] According to some embodiments of the present invention, referring to Figure 1-Figure 4 The discharge device 100 further includes an adapter and a second electrical connector 26. For example, the adapter may be a control circuit board 27. The second electrical connector 26 is located on the housing 22. The adapter is used to electrically connect the first electrical connector 21 and the second electrical connector 26.
