Technical field
The present invention relates to a kind of cooling structures for electric car charging gun chipware, belong to electric vehicle charging field.
Background technique
In terms of charging interface, state indicates AC charge port and direct-current charge port at present, and traditional conduction-type charge port can The maximum current of receiving is 250A (cable with 95mm2).New-energy automobile charge prepd by recent years market application and It examines, temperature rise increase is obvious, and the electric current of 200A or so just will appear with using the time to increase for DC high-power charge prepd at present Large area ablation situation, and the formula of increasingly sprawling is presented in the problem.Current A grades of vehicle course continuation mileage 200km's of electric car In the case of, fast charge needs 2 hours or so, has been far from satisfying the requirement of user, and the use body-sensing of user is very poor, Cause user not high to the degree of recognition of electric car.
The logical electric current of normal cable has standard requirements, and it is bigger to lead to load electric current for the bigger cable in section.Normal cable can be with Increased by increasing the area of section of cable it is logical carry electric current, but this also increases the difficulty of cable operation, at this moment because For the increase of the cross-section of cable, the radius bend that will result in cable becomes larger, and is allowed to bending difficulty.
Summary of the invention
The technical problem to be solved by the present invention is to provide one kind under the premise of not by increasing the cross-section of cable, can take away It gives off heat in charging process, solves the problem of charging for electric car with the excessive charge prepd ablation of charging current The cooling structure of rifle chipware.
In order to solve the above technical problems, the technical solution adopted by the present invention are as follows:
A kind of cooling structure for electric car charging gun chipware, including charging pipette tips, shell and locking wire pipe, it is described outer DC chipware component and water-cooled cable are provided in shell, the DC chipware component is hollow structure, and the DC chipware component includes phase The chipware of connection is connected with bend connector on the chipware, and the water-cooled cable includes insulating layer, is provided with two in the insulating layer Root big pipe, two small water pipes, two signal wires and ground line, are provided with copper wire in two big pipes, outside the copper wire It is enclosed with insulating radiation layer, forms intake tunnel between the insulating radiation layer and the big pipe, is in the small water pipe Aquaporin, the big pipe are connected with the chipware, and the small water pipe is connected with the bend connector, on the DC chipware component Each chipware crimped with the copper wire.
Including water tank, it is placed with insulating and cooling liquid and water pump in the water tank, is provided on the water tank and insulation is cooled down The radiator that liquid radiates, the water outlet of the water pump are connected with the end of the big pipe, and the end of the small water pipe is deep Enter into the water tank.
The temperature sensor for detecting the copper wire is provided in the shell, the temperature sensor is connected with controller, The controller is connected with the water pump and radiator.
The big pipe, small water pipe, signal wire and ground line twisted synthesizing cable.
It is connected between the electricity pipette tips and shell by self-tapping screw.
The chipware is made up of die casting, later turning, and the bend connector is that copper rod is made up of turning and drilling, institute It states and is fixed between chipware and the bend connector by welding manner.
Beneficial effects of the present invention: a kind of cooling structure for electric car charging gun chipware provided by the invention is adopted With the completely new construction of cable, the pressure cooling scheme band of water passage circulation system is formed using water pump, radiator, water tank and charging gun Walk the heat of cable sending.It then can then lead in the smaller situation of the cross-section of cable and carry bigger electric current, solve with charging current mistake Greatly, the problem of charge prepd ablation.Such charging gun can meet big charge power, greatly reduce the charging time, 400A's In the case of, charge 15min, can meet the course continuation mileage demand of electric car 100 degree electric (400km).
