The invention discloses a liquid-cooled cable for a new energy automobile and a charging pile, and when the liquid-cooled cable is applied to the charging pile and charges an electric vehicle, during working, refrigerant fluid of a liquid-cooled pipe in a cable body passes through a first through chamber, a second through chamber, a first one-way valve and a second one-way valve of a power supply connector, and then flows through the first one-way valve and the second one-way valve; when the power supply connector is connected with the charging pile, two paths of convection currents with opposite flowing directions are formed, refrigerant fluid shunted from one path flows into the charging pile to achieve cooling and then flows back to the power supply connector, and when the refrigerant fluid in the liquid cooling pipe of the cable body flows to the charging connector, due to the arrangement of the two communicated liquid passing chambers, the refrigerant fluid is convenient to flow back through one liquid passing chamber, and the power supply connector is convenient to charge. Therefore, the refrigerant fluid in the liquid cooling pipe can achieve a liquid circulation effect in the charging connector, the cable body, the power supply connector and the charging pile, so that a heating wire and a control core wire in the cable body can be conveniently and efficiently cooled, and the charging efficiency is improved.

    本发明公开了一种新能源汽车用液冷电缆及充电桩,其中液冷电缆在应用于充电桩并且对电车进行充电时,在工作时,电缆本体中的液冷管的制冷液通过供电接头的第一通室、第二通室、第一单向阀和第二单向阀后,会形成两路流通方向相反的对流,其中一路分流的制冷液会流入充电桩中实现冷却降温,进而回流至供电接头中,当电缆本体的液冷管中的制冷液流至充电接头时,由于两个相连通的通液室设置,因此便于制冷液通过其一通液室实现返流,因此液冷管内的制冷液可以在充电接头、电缆本体、供电接头和充电桩中实现液体循环流通的作用,进而便于高效地对电缆本体中发热的导线和控制芯线进行冷却降温的作用,从而提高充电效率。
