Embodiment Construction

[0016] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0017] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0018] Such as figure 1 As shown in —2, a cable cooling system for a charging gun mainly includes an insulating hose 2 filled with an insulating cooling liquid inside, and the insulating hose 2 is bundled with the wires 5 in the cable 6 and is insulated The gap between the hose 2 and the wire 5 is filled with a filler with good insulation and heat dissipation to conduct heat conduction and transfer the heat out. The surface of the cable is wrapped with several layers of fillers, so that the fillers are in direct contact with the outside air and conduct heat away as soon as possible. The gaps and o...

Abstract

The invention discloses a cable cooling system used for a charging gun. The system comprises an insulation flexible pipe filled with an insulation cooling liquid. The insulation flexible pipe and a lead in a cable are bundled into the cable, a gap between the insulation flexible pipe and the lead is filled with a filler with good insulation and heat dissipation performance, and a surface of the cable is wrapped by the filler. One end, close to a charging gun head jack, of the insulation flexible pipe is connected with a spiral cooling pipe with good thermal conductivity, one end of a cooling pipe is embedded into a port of the insulation flexible pipe in an interference fit mode, and the other end of the cooling pipe is connected to a circulating water cooling system through a water returnpipe to achieve dynamic circulating cooling. The cooling pipe is spirally and coaxially arranged on an outer wall of a metal spigot and socket pipe connected with the jack. An inserting portion of the lead is inserted into the spigot and socket pipe so that electrification is achieved. The cable of the charging gun can be rapidly cooled, charging efficiency is improved, and a service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of charging devices, in particular to a cable cooling system for charging guns. Background technique [0002] At present, the high-power charging gun cable has a large charging current, which will generate a large amount of heat in a short time, which will increase the temperature of the conductor and reduce the charging current, thereby reducing the charging efficiency. In addition, if the insulating material works under high temperature for a long time, it will accelerate the aging of the material, and the overall service life of the charging gun will also be reduced. Therefore, in order to improve charging efficiency and prolong service life, we must consider changing the design of the cable to achieve self-cooling of the cable. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and provide a cable cooling system for charging guns...
