Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling super charging, in particular to a liquid cooling super charging cooling system. Background Art

[0002] Liquid-cooled supercharging means setting up a special liquid circulation channel between the cable and the charging gun, adding liquid coolant for heat dissipation in the channel, and promoting the coolant circulation through a power pump, so as to bring out the heat generated during the charging process. The largest heat-generating working mode of electric vehicles is DC charging. In the charging scenario, the entire charging high-voltage circuit will generate a lot of heat. The greater the power, the greater the heat loss. According to the law of conservation of energy, heat needs to find a way to discharge it. Under high-power fast charging, from the charging facility end, the charging seat to the battery charging interface, enters the high-voltage contactor to the inside and surface of the battery cell. Liquid-cooled charging piles refer to the use of liquid cooling technology to set up a special liquid circulation channel between the cable and the charging gun, adding liquid coolant for heat dissipation in the channel, and promoting the coolant circulation through a power pump. Compared with traditional DC charging guns and cables, charging guns and charging cables with liquid cooling have added cooling pipes to the charging gun, cable, and charging pile circuits, and added cooling liquid pipes inside the cable. They can be compatible with two different requirements of 400V and 800V to ensure that the temperature rise of the charging interface does not exceed the standard.

[0003] A coolant tank is provided in the charging pile. The coolant flowing out of the coolant tank enters the charging gun through a pipe for cooling. The circulated coolant flows to the heat exchanger, and then flows back to the cooling box after dissipating the heat through the radiator. During the use of the radiator, the fan group is installed in the mounting frame, and the mounting frame is fixed in the fixing frame of the charging pile, so that the radiator is used. However, when the cooling fan is taken out for inspection and maintenance, the side panel of the fixing frame needs to be opened, and then the mounting frame is taken out from the fixing frame. The fan is connected to the wires inside the charging pile. If the wires are short, the wires will be pulled when the mounting frame is taken out, which may easily cause damage to the wires. If the wires are long, the wires may be entangled, which makes it inconvenient to carry out wiring operations. In order to prevent the wires from being pulled when the mounting frame is disassembled, a liquid-cooled supercharging cooling system is provided. Utility Model Content
