Description

Inner spiral structure conductor cable with insulating liquid cooling liquid communicated inside

Technical Field

Background

In the development process of the new energy automobile, the bottleneck that the charging time is too long and the customer demands are difficult to meet is encountered. In order to shorten the charging time, high-power charging is required, and the high-power charging puts higher requirements on the current carrying capacity of the charging cable;

the traditional practice for improving the current carrying capacity of the cable is to reduce the heat generation of the cable by adopting a large-sized conductor with smaller resistance. The large-size conductor is adopted, so that the cost is high, the self weight is large, the size is large, and the use is difficult. The scheme of adopting large-scale conductors only solves the problems that the low-stage high-power charging of current carrying 250A and below is hindered by the limit development of the dead weight and the size of a cable, the charging time of the charging line of the current carrying 250A and below is still greatly different from the oiling time of the traditional fuel automobile, and the quick charging requirement of customers in large-traffic occasions is difficult to meet;

the structure of the existing direct cooling type liquid cooling charging wire is shown in figures 1, 2 and 3, in the structure of the power wire, a linear conductor 24 is adopted, the linear conductor 24 is not bending-resistant in use structure, cannot recover after bending, and generates a phenomenon of blocking flow of cooling liquid, meanwhile, an inner conductor is loose (a cavity for flowing the cooling liquid is reserved between the linear conductor 24 and an insulating layer, and the linear conductor 24 and the insulating layer are not contacted, so that the insulating layer cannot be supported), irregular serial movement exists during use, uneven fluid cooling can be generated, heat conduction is uneven, and the heat conduction efficiency is low.
