A circulating liquid cooling charging gun disclosed by the present invention comprises a charging pile outer cover and a charging gun, the charging gun is arranged on one side of the outer part of the charging pile outer cover, a gun sleeve for supporting the charging gun is fixed on the outer side of the charging pile outer cover, the bottom of the charging gun is connected with a cable shell, a cooling unit is arranged on one side of the bottom of the charging pile outer cover, and the cooling unit is connected with the charging pile outer cover. The bottom of the cable housing is provided with a supporting pipe which is communicated with the cooling unit. The cable shell is a vertically-through flexible insulating tube, and the charging gun comprises a shell with a cooling cavity in the middle. The cable has the beneficial effects that the two groups of cooling pipes which are distributed in a crossed manner and spirally extend are arranged in the cable shell, and insulating oil is guided into the cooling pipes and the cooling cavity through the liquid pump to be matched with the cooling unit to form a cooling loop, so that the insulating oil in the charging gun at a higher position and the cooling pipes is reinjected into the cooling unit when the cable is not charged; the weight of the charging gun and the charging cable is reduced, and the convenience of taking and operating the charging gun and pulling the charging cable by personnel is improved.

    本发明公开了一种循环式液冷充电枪,包括充电桩外罩和充电枪,所述充电枪设置于所述充电桩外罩外部一侧,且所述充电桩外罩外侧固定有支撑充电枪的枪套,所述充电枪底部连接有线缆壳体,所述充电桩外罩底部一侧设置有冷却机组,且线缆壳体底部设置有连通冷却机组的支撑管;线缆壳体为竖向贯通的柔性绝缘管,充电枪包括中部设置冷却腔的外壳。有益效果在于:本发明通过在线缆壳体内部设置两组交叉分布并螺旋延伸的冷却管,通过液泵将绝缘油导入冷却管和冷却腔内配合冷却机组形成冷却回路,以在未充电时处于较高位置的充电枪和冷却管中的绝缘油回注到冷却机组中,降低充电枪和充电线缆的重量,提高人员拿取操作充电枪和牵拉充电线缆的便利性。
