Cooling tube in described first main conductor and the cooling tube company of being formed each other in described second main conductor Logical loop, the cryogenic fluid flowing into from one of cooling tube passes through another cooling tube and flows out.
The connection end of the cooling tube in described first main conductor and the cooling tube in described second main conductor is passed through back Turn U-tube to connect.
Described cooling tube is arranged concentrically with described main conductor.
Described cable also includes oversheath, and described main conductor is arranged in described oversheath.
Described cable is charging cable, is additionally provided with gnd conductor and holding wire conductor in described oversheath.
It is additionally provided with packing material in described oversheath.
The tubing of described cooling tube is polyurethane(PU)Or silica gel or Teflon.
A kind of wire, including conductor, is internally provided with cooling tube in described conductor, transmits for cold in described cooling tube The cryogenic fluid of described conductor.
Beneficial effects of the present invention:
Cooling tube is arranged in main conductor the cable of the present invention, farthest reduces conductor temperature.Charging cable adopts The cable of the present invention, compared with the existing charging cable with psychrophore, can improve refrigerating efficiency further, and simplify Charging cable internal structure.
Brief description
Fig. 1 is a kind of schematic cross-section of embodiment of charging cable of the present invention;
Fig. 2 is the schematic perspective view of charging cable shown in Fig. 1.
Specific embodiment
Hereinafter embodiments of the present invention are elaborated.It is emphasized that what the description below was merely exemplary, Rather than in order to limit the scope of the present invention and its application.
Refering to Fig. 1 and Fig. 2, in one embodiment, a kind of cable, including many main conductor and each main conductor of cladding Main line insulating barrier 5,6, be internally provided with cooling tube in described main conductor, transmit described for cooling down in described cooling tube The cryogenic fluid of main conductor.
In a preferred embodiment, described many main conductor include the first main conductor 1 and the second main conductor 3, institute State the first main conductor 1 and the inside of described second main conductor 3 is each provided with described cooling tube 2,4.Described cable is permissible It is direct current charging cable, the first main conductor 1 can be DC+ main conductor, the second main conductor 3 can be DC- main conductor.
In a more preferred embodiment, in the cooling tube 2 and described second main conductor 3 in described first main conductor 1 Cooling tube 4 form the loop of connection each other, the cryogenic fluid flowing into from one of cooling tube 2 passes through another and cools down Pipe 4 flows out.
In a more preferred embodiment, in the cooling tube 2 and described second main conductor 3 in described first main conductor 1 Cooling tube 4 connection end pass through turn round U-tube(Not shown)Connect.Need exist for illustrating, U-tube simply realizes first The one of which connected mode of the cooling tube 4 in the cooling tube 2 in main conductor 1 and the second main conductor 3, other any can Realize the mode of cooling tube 4 revolution in the cooling tube 2 and the second main conductor 3 in the first main conductor 1, for example permissible Also may be used by the structure of tank.
