With the wide use of new energy vehicles, people have an increasing demand for charging equipment for charging new energy vehicles. In order to solve the problems of lack of charging equipment, difficulty in parking and difficulty in charging, a plurality of charging robots are put into use in a parking lot to charge a new energy automobile at present. However, when the charging robot is used for charging and discharging with a large multiplying power, a large amount of heat is generated, which may cause the temperature of the battery module 30 of the charging robot to be too high, and further affect the performance and the service life of the battery module 30.
For this reason, in the prior art, the battery module 30 of the charger robot is usually thermally managed by air cooling or liquid cooling. However, the air cooling type has low heat exchange efficiency, and is difficult to meet the requirements of high protection level and high charge-discharge rate; the liquid cooling system has high heat exchange efficiency, but the liquid cooling system is complex, high in cost and large in size, and the requirements of small size and flexible movement of the charging robot are difficult to meet.
In view of the above, the present application provides a new mobile charging robot to solve at least one problem faced in the prior art. Referring to fig. 1 and 2, the mobile charging robot includes a mobile body 50 and a heat exchange cabinet 10. The movable body 50 includes a housing 51, and a battery module 30 and a liquid cooling system 20 respectively disposed in the housing 51, the liquid cooling system 20 is matched with the battery module 30 for cooling the battery module 30, and the liquid cooling system 20 includes a first connector 24. The heat exchange cabinet 10 includes a cabinet 11 and a heat exchange system 12 disposed in the cabinet 11, wherein the heat exchange system 12 includes a second joint 128. When the moving body 50 needs to exchange heat, the moving body 50 is communicated with the second connector 128 through the first connector 24, so as to exchange heat for the refrigerant in the liquid cooling system through the heat exchange system 12 in the heat exchange cabinet 10.

The specific arrangement of the liquid cooling system 20 and the battery module 30 is not particularly limited, as long as the battery module 30 can be cooled. For example, the liquid cooling system 20 may be disposed opposite and adjacent to the battery module 30. In this way, the contact area between the liquid cooling system 20 and the battery module 30 can be further increased, so that the cooling effect of the battery module 30 is better.

It should be understood that the heat conductive material may be fully laid between the liquid cooling system 20 and the battery module 30; or may be filled in the gap between the liquid cooling system 20 and the battery module 30 (that is, when the liquid cooling system 20 and the battery module 30 cannot be completely attached, the heat conducting material is filled in the gap between the two), so that the temperature of the battery module 30 can be further reduced.
The heat exchange cabinet 10 is used for exchanging heat for the liquid cooling system 20. That is, when the temperature of the refrigerant in the liquid cooling system 20 rises to the threshold value, the heat exchange cabinet 10 may exchange heat with the refrigerant in the liquid cooling system 20, and thus, the temperature of the refrigerant in the liquid cooling system 20 may be reduced.
Specifically, when the temperature of the refrigerant in the liquid cooling system 20 rises to the threshold value, the moving body 50 needs to be moved to the vicinity of the heat exchange cabinet 10 first, and the liquid cooling system 20 and the heat exchange cabinet 10 are connected, so that the heat exchange cabinet 10 and the liquid cooling system 20 can be communicated, and then the refrigerant in the liquid cooling system 20 is subjected to heat exchange through the heat exchange cabinet 10, so that the temperature of the refrigerant in the liquid cooling system 20 is reduced to an appropriate temperature. The threshold of the temperature of the refrigerant in the liquid cooling system 20 should be determined according to actual conditions.
It should be noted that, in the present application, the heat exchange cabinet 10 and the liquid cooling system 20 in the mobile main body 50 are detachably connected, the liquid cooling system 20 is disposed inside the mobile main body 50, and the heat exchange cabinet 10 is independent from the mobile main body 50 of the charger robot, so that when heat exchange is not required, the liquid cooling system 20 and the heat exchange cabinet 10 can be disconnected, so that the mobile main body 50 can freely move; when heat exchange is needed (for example, the temperature of the refrigerant in the liquid cooling system 20 rises to a threshold value), the liquid cooling system 20 and the heat exchange cabinet 10 can be connected, and then the refrigerant in the liquid cooling system 20 is subjected to heat exchange and cooling through the heat exchange cabinet 10, so that the liquid cooling system 20 is always at a proper temperature, and the potential safety hazard of the battery module 30 caused by the overhigh temperature in the liquid cooling system 20 is avoided.
In addition, this application is installed liquid cooling system 20 inside charging robot, and will change heat cabinet 10 outside being independent of charging robot's second body, like this, both can ensure charging robot's battery module 30's cooling demand, can satisfy charging robot again and keep the requirement that the size is little, the removal is nimble in the course of the work.
So, the liquid cooling system 20 of the mobile charging robot that this application provided is the part that is directly used for cooling down to battery module 30 promptly, and heat exchange cabinet 10 is then as the auxiliary assembly of liquid cooling system 20 for carry out the heat transfer to liquid cooling system 20. During the in-service use, heat exchange cabinet 10 can set up in fixed position, and liquid cooling system 20 then locates the inside of charging the robot, and like this, when charging, liquid cooling system 20 can follow the charging the robot and remove, and heat exchange cabinet 10 is unmovable, so will do benefit to the nimble removal of charging the robot.
In summary, the present application provides a mobile charging robot, which includes a mobile main body 50 and a heat exchange cabinet 10. The movable body 50 includes a housing 51, and a battery module 30 and a liquid cooling system 20 respectively disposed in the housing 51, the liquid cooling system 20 is matched with the battery module 30 for cooling the battery module 30, and the liquid cooling system 20 includes a first connector 24. The heat exchange cabinet 10 includes a cabinet 11 and a heat exchange system 12 disposed in the cabinet 11, wherein the heat exchange system 12 includes a second joint 128. When the moving body 50 needs to exchange heat, the moving body 50 is communicated with the second connector 128 through the first connector 24, so as to exchange heat for the refrigerant in the liquid cooling system through the heat exchange system 12 in the heat exchange cabinet 10. Therefore, when the mobile charging robot is used, the liquid cooling system 20 can effectively cool the battery module 30 of the mobile charging robot, so that the battery module 30 is always at a safe temperature; when the temperature of the refrigerant in the liquid cooling system 20 is too high, the liquid cooling system 20 and the heat exchange cabinet 10 can be communicated, so that the refrigerant in the liquid cooling system 20 is subjected to heat exchange through the heat exchange cabinet 10, and the refrigerant in the liquid cooling system 20 is cooled to a proper temperature. The liquid cooling system 20 is arranged inside the shell, so that the cooling requirement of the battery module 30 can be met, the heat exchange cabinet 10 is detachably connected with the liquid cooling system 20, and the liquid cooling system 20 can be connected with the heat exchange cabinet 10 or not connected with the heat exchange cabinet 10 according to the requirement, so that the liquid cooling system 20 can be subjected to heat exchange through the heat exchange cabinet 10 when needed, and the cooling function of the battery module 30 by the liquid cooling system 20 is realized; when the mobile charging robot does not need to be moved, the liquid cooling system 20 is disconnected from the heat exchange cabinet 10, so that the size of the mobile charging robot can be reduced when the mobile charging robot moves, and the moving flexibility of the mobile charging robot is improved.
