The invention belongs to the technical field of charging guns, and discloses a liquid cooling charging gun for charging an electric vehicle. Comprising a charging gun main body and a charging cable connected with the charging gun main body, and a conductive core body is arranged in the charging cable. Through the arrangement of the heat dissipation and cooling assembly, when an external circulating pump drives cooling liquid passing through a heat exchanger to circularly flow in a liquid cooling pipe, the cooling liquid firstly passes through a second T-shaped pipe, a circular ring pipe and a connecting pipe to enter a plurality of spiral pipes; due to the fact that the first spiral heat-conducting fins make direct contact with the conductive core body, the heat dissipation area is increased, the heat conduction performance of the first spiral heat-conducting fins is better than that of an insulation sleeve, cooling liquid flowing through the spiral pipes can directly take away heat, the cooling liquid enters the liquid cooling pipes and can flow along the spiral fins in the liquid cooling pipes, and the spiral fins can increase the heat dissipation efficiency and the heat dissipation area; and meanwhile, the liquid cooling pipe can be radially supported, so that the liquid cooling pipe is prevented from being deformed under the action of external force.

    本发明属于充电枪技术领域,本发明公开了一种用于电动汽车充电的液冷充电枪;包括充电枪主体和与充电枪主体连接的充电线缆,所述充电线缆内设置有导电芯体。本发明通过设置散热冷却组件,当外部循环泵驱动经过热交换器的冷却液在液冷管内循环流动时,冷却液先通过第二T形管、圆环管和连接管进入多个螺旋管内,由于第一螺旋导热片与导电芯体直接接触增大散热面积且其导热性能优于绝缘套,螺旋管内流经的冷却液可直接将热量带走,冷却液进入液冷管内,冷却液在液冷管内会沿着螺旋片流动,螺旋片可增加散热效率和散热面积,同时还能够对液冷管起到径向支撑作用,防止在外力作用下使得液冷管发生变形。
