Existing electric automobile is mostly the demand that its charging is met by charging gun, and charging gun plays electric automobile and is connected with charging pile
Function served as bridge.
New-energy automobile needs to be charged, and wants to fill same electricity that the time is short again, then need to carry out high current to fill
Electricity, and large current charge can then cause terminal caloric value big, there is potential safety hazard.
Therefore, how to solve its radiating will be can quickly fast electricity and the safety that charges major issue.
The content of the invention
It is a primary object of the present invention to overcome the deficiencies in the prior art, there is provided one kind can radiate so as to true in time
Protect the charging equipment cooling system that radiate and can ensure that the safety that charges in time in large current charge.
To achieve the above object, the present invention provides a kind of charging equipment cooling system, including charging gun, charging cable, electricity
Source module, radiator, circulating pump and circulation of fluid pipeline.Circulation of fluid pipeline is built-in with coolant.Charging gun, charging cable,
Power module is together in series by circulation of fluid pipeline and takes away heat by circulation of fluid pipeline.Circulation of fluid pipeline is by heat
Radiator is transferred to be radiated.The driving force of the liquid in circulation of fluid pipeline is provided by circulating pump.
Preferably, the circulating pump, radiator, power module, charging cable and charging gun have the inlet and outlet connectors of fluid,
Circulating pump, radiator, power module, charging cable and charging gun are sequentially connected in series with flexible pipe, the flexible pipe is followed for described
Ring fluid line.
Preferably, the charging cable includes the main line insulating barrier of at least one main conductor and cladding main conductor,
The cryogenic fluid or coolant that are internally provided with cooling tube, transmit for cooling down main conductor in cooling tube of main conductor, should
Cooling tube forms the circulation of fluid pipeline.
Preferably, the power module is the power module of circulation of fluid cooling.
As described above, charging equipment cooling system of the present invention passes through all parts example of the circulation of fluid pipeline to charging equipment
As charging gun, charging cable, power module are radiated, circulation of fluid pipeline transfers heat to radiator and is radiated, this
The heat of each part can be distributed into the external world in time such that it is able to ensure to radiate and can ensure that in time in large current charge
Charge safety.
Brief description of the drawings
Fig. 1 is the structured flowchart of charging equipment cooling system of the present invention；
Fig. 2 is the cross section structure schematic diagram that charging equipment cooling system shown in Fig. 1 unifies embodiment charging cable.
