The invention relates to the technical field of charging guns, in particular to a high-power direct-current charging gun which comprises a high-voltage cable, a heat dissipation assembly, a shell and a pressurization assembly, and the top of the shell is fixedly provided with a grab handle; a barrel is fixedly mounted on the right side of the shell, and a plug is fixedly mounted on the right side of the barrel; and a high-voltage cable is fixedly mounted on the left side of the shell. According to the charging gun, the diversion pipe and the heat conduction cylinder are filled with the heat conduction agent, paraffin is changed from a solid phase to a liquid phase to absorb heat after being heated according to the phase change principle of the paraffin in the heat conduction agent, and the charging gun has excellent flame retardant property, so that the heat conduction agent absorbs a large amount of heat from the interior of the charging gun; the liquid heat conduction agent is driven by heat to circularly flow in the flow guide pipe and the heat conduction cylinder, so that heat dissipation of the charging gun is promoted, and in a conventional state, the solid heat conduction agent is stable in property and free of liquid leakage, so that the safety of the charging gun after frequent use is guaranteed.
本发明涉及充电枪技术领域,尤其涉及一种大功率直流充电枪,其技术方案包括高压电缆,散热组件,壳体和增压组件,所述壳体的顶部固定安装有握柄;所述壳体的右侧固定安装有筒体,所述筒体的右侧固定安装有插线头;所述壳体的左侧固定安装有高压电缆。本发明通过在导流管和导热筒中填充导热剂,通过导热剂中石蜡的相变原理,使石蜡在受热后,由固态相变为液态开始吸热,并具备优良的阻燃性能,进而使导热剂吸收大量来自于充电枪内部的热量,并依靠热量驱使液态的导热剂在导流管和导热筒中循环流动,进而促进充电枪散热,并且在常规状态下,处于固态的导热剂性质稳定,且不存在漏液的情况,进而保证了充电枪在频繁使用后的安全性。
