Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example one

As shown in fig. 1, the embodiment provides a liquid cooling cable for a charging pile, which includes a plurality of cable cores 1 and an outer sheath 2, and a filling layer 3 is disposed between the cable cores 1 and the outer sheath 2. The outer sheath 2 is prolate, a plurality of cable cores 1 are arranged in the outer sheath 2 side by side, and a gap is arranged between the cable core 1 at the two ends and the filling layer 3 and is filled with insulating cooling liquid 4. The insulating cooling liquid 4 adopts fluoridized liquid cooling agent. The outer sheath 2 is a flexible plastic sheath. The ratio of the length to the width of the cross section of the outer sheath 2 is not limited, preferably the ratio is greater than 2.5.

In this embodiment, the cable core 1 includes two conductor cores 13, a ground core 11 and two signal cores 12. The conductor wire core 13 is located the most both ends of oversheath 2, and ground wire core 11 is located oversheath 2 central authorities, and signal wire core 12 symmetry sets up the both sides at ground wire core 11. The section of the ground wire core 11 is circular, the section of the conductor wire core 13 is circular, and the section of the signal wire core 12 is 8-shaped.

During operation, the insulating coolant around the conductor sinle silk 13 can cool off the conductor sinle silk 13, has increased the current-carrying capacity of cable, avoids the conductor sinle silk 13 cross-section too big cable diameter too thick that leads to.
