A liquid metal series cooling cable

Abstract

The invention relates to a liquid metal series cooling cable, which includes a charging terminal assembly, a hollow cable, a cooling assembly, a shunt assembly, a first liquid-insulated rotor assembly, and a second liquid-isolated rotor assembly; the shunt assembly includes a bare conductor, an insulating tube, a No. terminal, No. 2 conductive terminal, C-shaped electromagnet and conductive shunt; C-shaped electromagnets are installed on No. 1 conductive terminal and No. 2 conductive terminal; One end of the cable body is connected, and the two conductive shunt parts are respectively connected to the two conductive terminals through bare conductors; the other ends of the cable bodies of the two hollow cables are in sealing communication with their respective charging terminal assemblies; the second liquid-proof rotor assembly is arranged on the two On the connecting pipeline of the two charging terminal assemblies; the insulating tube, the cable body of the two hollow cables and the connecting pipeline of the two charging terminal assemblies form a closed loop, and the closed loop is filled with liquid metal. The energy transfer path of the cable is shorter and more efficient.

Description

technical field [0001] The invention belongs to the technical field of high-power charging piles used by electric vehicles, in particular to a liquid metal series cooling cable. Background technique [0002] With the popularization of new energy electric vehicles, the demand for charging piles is also increasing rapidly, especially charging piles characterized by short charging time and high charging power are becoming more and more prominent. Due to the high power, the more heat is generated during charging, the more heated the charging terminals and cables are, and the higher the temperature is, it is prone to unstable charging and burning of the charging terminals. At present, cooling cables in series or parallel form are commonly used to reduce the temperature at the charging terminals. [0003] The document with the application number 201810574784.7 discloses a series cooling method of DC+ and DC- special liquid-cooled cables for DC 600A charging guns. The liquid-coole...

[0003] The document with the application number 201810574784.7 discloses a series cooling method of DC+ and DC- special liquid-cooled cables for DC 600A charging guns. The liquid-cooled method includes two liquid-cooled cables, DC+ and DC-, and each liquid-cooled cable There are cooling liquid passages inside, and a cooling circuit is formed between the two cables by setting a connecting component between the liquid cooling terminals; the cooling liquid is circulated through the hydraulic pump, and then the soft wire is cooled. , the mechanical transmission efficiency of the traditional hydraulic pump is low; and the coolant always flows in the same direction in the cooling circuit, resulting in a good cooling effect when the coolant passes through one liquid-cooled cable, and a weaker cooling effect when it passes through another liquid-cooled cable Difference
