As a preferred embodiment, it in the cooling means of the high power DC charge connector, is filled in described Be respectively arranged with cooling chamber around direct current inserting terminal in electric rifle, opened up in each cooling chamber two be respectively used to feed liquor and The pipe interface of liquid is returned, the delivery outlet of the inlet pipe and the input port on liquid back pipe road are managed with two of corresponding cooling chamber respectively Road interface is connected.
As a preferred embodiment, in the cooling means of the high power DC charge connector, described a pair Temperature sensor is provided in direct current inserting terminal.
As a preferred embodiment, in the cooling means of the high power DC charge connector, the temperature Sensor is thermistor.
As a preferred embodiment, in the cooling means of the high power DC charge connector, the pressure is cold But a kind of specific generation method of liquid are as follows: the coolant liquid in liquid reserve tank is extracted using hydraulic pump, is formed in the delivery outlet of hydraulic pump Pressure coolant liquid is sent to inlet pipe；Pressure coolant liquid in liquid back pipe road finally by being back in liquid reserve tank.
As a preferred embodiment, in the cooling means of the high power DC charge connector, in real time to storage The temperature of coolant liquid is detected in liquid case, when the temperature of coolant liquid in liquid reserve tank is greater than setting ceiling temperature value, is then being pressed Power coolant liquid cools down it before returning to liquid reserve tank by liquid back pipe road.
As a preferred embodiment, in the cooling means of the high power DC charge connector, the pressure After coolant liquid is come out by liquid back pipe road, allows it by air cooler, cooled down and then returned liquid storage to it by air cooler Case.
As a preferred embodiment, in the cooling means of the high power DC charge connector, described is hydraulic Pump automatically shuts down the diaphragm pump of pressure protecting function using band, and when pump discharge pressure reaches setup pressure value, diaphragm pump is automatic It shuts down, at the same time, cuts off the connection of charging gun and charge power supply.
As a preferred embodiment, in the cooling means of the high power DC charge connector, the cooling Liquid is any one or any combination between them in insulating heat-conductive oil, softened water and ethylene glycol.
The beneficial effects of the present invention are: the present invention is by cooling down charging gun and cable, also, in cooling procedure In detected by the temperature to direct current inserting terminal, when temperature be greater than setting alarm temperature value when, then cut off charging gun with The connection of charge power supply.The volume of charger and the line footpath of cable can be greatly reduced, in this way so as to substantially reduce behaviour Make the labor intensity of personnel；Moreover, the safety of entire charge connector is also ensured.In addition to this, the present invention is also real-time Ground detects the temperature of coolant liquid in liquid reserve tank, when the temperature of coolant liquid in liquid reserve tank is greater than setting ceiling temperature value, Then it is cooled down before pressure coolant liquid returns to liquid reserve tank by liquid back pipe road, to improve coolant liquid to direct current inserting terminal Cooling effect, reduce the temperature of direct current inserting terminal, enable described charge connector long-time, reliablely and stablely work Make.
Specific embodiment
Below with reference to embodiment, a kind of cooling means of high power DC charge connector described in the present invention is described in detail Specific embodiment.
High power DC charge connector of the present invention includes: charging gun and connection charging gun and charge power supply Cable, parallel therewith inlet pipe and liquid back pipe road are provided in cable, around a pair of of direct current in charging gun Inserting terminal is respectively arranged with cooling chamber, and two are opened up in each cooling chamber and is respectively used to feed liquor and returns the pipe interface of liquid, The delivery outlet of the inlet pipe and the input port on liquid back pipe road are connected with two pipe interfaces of corresponding cooling chamber respectively, are For the sake of insurance, it is provided with the thermistor as temperature sensor in a pair of of direct current inserting terminal；Specific cooling side Method are as follows: allow pressure coolant liquid to enter in charging gun along the inlet pipe parallel with cable, then along with cable simultaneously Capable liquid back pipe road returns, and pressure coolant liquid is during traveling, to a pair of of direct current inserting terminal in cable and charging gun It is cooled down, and the temperature of real-time sampling direct current inserting terminal, when the temperature of direct current inserting terminal is more than setting alarm temperature value When (being typically set at 90 degree), then the connection of charging gun and charge power supply is cut off；In the present embodiment, the hydraulic pump uses Be diaphragm pump that band automatically shuts down pressure protecting function, it may be assumed that the diaphragm pump band automatically shuts down pressure protecting function, when its output When the pressure of mouth is greater than rated pressure value, then it is automatically turned off, certainly, can generally also cuts off the company of charging gun and charge power supply at this time It connects；The coolant liquid is any one or any combination between them in insulating heat-conductive oil, softened water and ethylene glycol.
In practical application, coolant liquid is recycled by liquid reserve tank and hydraulic pump, it may be assumed that extract liquid reserve tank using hydraulic pump In coolant liquid, form pressure coolant liquid in the delivery outlet of hydraulic pump and be sent to inlet pipe, into the cooling of direct current inserting terminal Then room flows to liquid back pipe road by cooling chamber, then flow to air cooler by liquid back pipe road, finally returns into liquid reserve tank.Moreover, Temperature sensor is installed in liquid reserve tank to detect the temperature of coolant liquid in liquid reserve tank, when the temperature of the coolant liquid in liquid reserve tank More than 50 degree, then: starting air cooler work cools down the coolant liquid flowed out by return line.
Further, since the leakage of coolant liquid influences whether that the normal use of charge connector even threatens personal safety, it is This, usually also needs using liquid leakage detection system.In view of the cost of sensor, mounting means, measurement accuracy, usually select With diaphragm type liquid leakage sensor, liquid leakage detection system working principle are as follows: have biography on diaphragm type liquid leakage sensor Line layer is led, each unit area has certain resistance value on transmission line layer.When leaking generation, conducting liquid and conduction Line layer contact, resistance value will change, and diaphragm type liquid leakage sensor terminal is provided with controller, and controller should The corresponding voltage value of resistance value is compared with the voltage value of setting, if it is inconsistent, sound an alarm, and cut off charging gun with The connection of charge power supply.
In conclusion only presently preferred embodiments of the present invention, is not used to limit the scope of implementation of the present invention, it is all according to Equivalent changes and modifications made by shape described in scope of the invention as claimed, construction, feature and spirit should all be included in this In the scope of the claims of invention.
