Example (b):
in this embodiment, with reference to fig. 1-4, the liquid-cooled charging pile includes at least one first circulating cooling assembly, at least one second circulating cooling assembly, and at least one heat dissipation assembly; the first circulating cooling assembly comprises a first liquid storage tank 11, a first driving source 12 and a charging module 13, the heat dissipation assembly, the first liquid storage tank 11, the first driving source 12 and the charging module 13 are connected to form a closed first cooling circulating loop, the first liquid storage tank 11 is used for storing first cooling liquid, and the first driving source 12 is used for driving the first cooling liquid to flow in the first cooling circulating loop; the second circulating cooling assembly comprises a second liquid storage tank 21, a second driving source 22 and a charging gun 23, the heat dissipation assembly, the second liquid storage tank 21, the second driving source 22 and the charging gun 23 are connected to form a closed second cooling circulating loop, the second liquid storage tank 21 is used for storing second cooling liquid, and the second driving source 22 is used for driving the second cooling liquid to flow in the second cooling circulating loop; the charging gun 23 is electrically connected to the charging module 13; the heat dissipation assembly is used for conducting heat of the first cooling circulation loop and the second cooling circulation loop.

The charging of hundreds of kilowatts can be easily realized, and the protection is high.
In this embodiment, the arrangement order of the modules in the first cooling circulation circuit may be different. Specifically, in the first cooling circulation circuit, the arrangement order of the modules in the flow direction of the first cooling liquid may be: the first liquid storage tank 11, the first driving source 12, the charging module 13 and the heat dissipation assembly are sequentially arranged; or, the first liquid storage tank 11, the first driving source 12, the heat dissipation assembly and the charging module 13 are sequentially arranged; or, the first liquid storage tank 11, the charging module 13, the first driving source 12 and the heat dissipation assembly are sequentially arranged; or, the first liquid storage tank 11, the charging module 13, the heat dissipation assembly and the first driving source 12 are sequentially arranged; or, the first liquid storage tank 11, the heat dissipation assembly, the first driving source 12 and the charging module 13 are sequentially arranged; alternatively, the first reservoir 11, the heat dissipating assembly, the charging module 13, and the first driving source 12 are sequentially arranged.
In this embodiment, the arrangement order of the modules in the second cooling circulation circuit may be different. Specifically, in the second cooling circulation circuit, the arrangement order of the modules in the flow direction of the second cooling liquid may be: the second liquid storage tank 21, the second driving source 22, the charging gun 23 and the heat dissipation assembly are sequentially arranged; or the second liquid storage tank 21, the second driving source 22, the heat dissipation assembly and the charging gun 23 are sequentially arranged; or the second liquid storage tank 21, the charging gun 23, the second driving source 22 and the heat dissipation assembly are sequentially arranged; or, the second liquid storage tank 21, the charging gun 23, the heat dissipation assembly and the second driving source 22 are sequentially arranged; or, the second liquid storage tank 21, the heat dissipation assembly, the second driving source 22 and the charging gun 23 are sequentially arranged; alternatively, the second reservoir 21, the heat dissipating assembly, the charging gun 23, and the second driving source 22 are arranged in this order.
It should be understood that the arrangement order of the modules in the first cooling circulation loop and the arrangement order of the modules in the second cooling circulation loop are not affected, that is, any arrangement order of the modules in the first cooling circulation loop and any arrangement order of the modules in the second cooling circulation loop can be combined with each other, as long as two cooling circulation loops share one heat dissipation assembly.
The first cooling liquid is oil, water, air, propylene glycol or ethylene glycol; the second cooling liquid is oil, water, air, propylene glycol or ethylene glycol. The first drive source 12 and the second drive source 22 may each employ a pump body.
A cooling pipeline can be connected between adjacent functional modules (referring to the first liquid storage tank 11, the first driving source 12, the charging module 13 or the heat dissipation component in the first cooling circulation loop, or referring to the second liquid storage tank 21, the second driving source 22, the charging gun 23 or the heat dissipation component in the second cooling circulation loop), the cooling pipeline can be a hard pipeline or a soft pipeline, and can be selected according to the relative position relationship of the adjacent functional modules, for example, if the positions of the adjacent functional modules are relatively fixed, a hard pipeline is selected, if the positions of the adjacent functional modules are changed during use, a soft pipeline is selected, no matter what form the cooling pipeline is adopted, the outer side of the cooling pipeline can be coated with an insulating layer, and the insulating layer can be made of foam, polystyrene foam, polyurethane foam material and the like, the heat insulating layer can also be made of ceramic fiber blanket, aluminum silicate felt, alumina, silicon carbide fiber, aerogel felt, glass wool, rock wool, expanded perlite, micro-nano heat insulation, foaming cement and other materials, the materials can be mixed for use, and talcum powder, nylon, polytetrafluoroethylene, polyimide and other materials can be used as a mixing agent during mixing. The structural form of the cooling duct for communicating the adjacent functional modules is not limited, and any duct structure may be used as long as the duct structure can allow the first cooling liquid or the second cooling liquid to flow and has a heat preservation function.
In the cooling circulation loop, for the functional modules with heat exchange, such as the charging module 13, the charging gun 23 and the heat dissipation assembly, a heat exchange structure may be arranged inside, it should be understood that, since the cooling circulation loop is a closed loop, the first cooling liquid or the second cooling liquid does not exchange material with other cooling media when heat exchange occurs, that is, the first cooling liquid or the second cooling liquid only flows through the inside of the heat exchange structure, and then the heat exchange with the corresponding module is realized through the heat exchange structure; for the heat generating functional modules such as the charging module 13 and the charging gun 23, the corresponding heat exchange structure may be disposed at the heat generating position, for example, the outer surface of the heat exchange structure directly contacts the heat generating component in the heat generating functional module, or a heat conducting medium, such as heat conducting oil, heat conducting glue, etc., is disposed between the heat exchange structure and the heat generating component of the corresponding heat generating functional module, or the heat exchange structure directly serves as a part of the heat generating component, so that the heat exchange process is more direct and efficient, and the cooling effect is better; for the functional module such as the heat dissipation assembly, the heat exchange structure may refer to the arrangement form in the foregoing manner, and is not limited herein.
In some embodiments, the first cooling circulation loop may include a plurality of charging modules 13 connected in parallel, specifically, before the plurality of charging modules 13 connected in parallel, the first cooling liquid may be divided into multiple paths with the same number as the charging modules 13 by one path, and the cooling liquid in each path flows through the corresponding charging module 13, and finally merges into one path; the second cooling circulation loop may also include a plurality of charging guns 23 connected in parallel, the cooling liquid may be divided into a plurality of paths in accordance with the number of the charging guns 23 by one path before the plurality of charging guns 23 connected in parallel, and the cooling liquid of each path may flow through the corresponding charging guns 23 respectively and finally merge into one path. In this way, the cooling of the plurality of charging modules 13 and/or the plurality of charging guns 23 can be realized, which is more efficient, and on the basis, for the structure where the plurality of cooling fluids (the first cooling fluid or the second cooling fluid) exist, a valve controlled by the controller may be provided, the valve is preferably an electromagnetic valve and may be a flow valve, the controller may control the action of the valve according to the heating state of the functional module (the charging module 13 or the charging gun 23) corresponding to the cooling fluid of the current path, for example, when the current temperature of the corresponding functional module exceeds a first preset temperature threshold value, the valve is controlled to be opened or the valve circulation is controlled to be increased, when the current temperature of the corresponding functional module is lower than a second preset temperature threshold value, the valve is controlled to be closed or the valve circulation is controlled to be decreased, and furthermore, the first driving source 12 (or the second driving source 22) may also be controlled by the controller, that is, when the current temperature of all the self-heating functional modules in the first cooling circulation loop (or all the self-heating functional modules in the second cooling circulation loop) is lower than the third preset temperature threshold, the controller controls the first driving source 12 (or the second driving source 22) to close or reduce the output power, and when a certain self-heating functional module in the first (or the second) cooling circulation loop exceeds the corresponding first preset temperature threshold, the controller controls the first (or the second) driving source to work or increase the output power, so that the cooling of the corresponding functional module can be realized more flexibly and efficiently by controlling the flow rate of the cooling liquid of the corresponding path, and the energy is saved more.
