Description

Technical Field

[0001] The utility model relates to the technical field of chargers, and more specifically to a cooling structure for a liquid-cooled charging gun which is easy to assemble. Background Art

[0002] The function of the charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in parking lots or charging stations in public buildings and residential areas. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. The charging gun head of the prior art is prone to generate a large amount of heat after long-term use, which can easily cause damage to the equipment. The problems existing in the prior art are: the existing equipment has poor heat dissipation effect, and the heat generated during use cannot be dissipated in time, which can easily burn the equipment, causing damage to the equipment, affecting the normal use of the equipment, and reducing the service life of the equipment.

[0003] The existing patent is based on a gun head for a liquid-cooled fast charging pile. The patent authorization number is CN 217124575 U. By setting a main body, a liquid cooling rack, a liquid cooling cavity, a liquid cooling pipe, a heat sink and a heat dissipation hole, the cooling plate is annular and can produce a temperature difference in the coolant in the liquid cooling cavity, which is convenient for the liquid cooling pipe to circulate heat and increase the contact area between the liquid cooling pipe and the main body. This solves the problem that the heat dissipation effect of the existing equipment is poor, the heat generated during use cannot be dissipated in time, and the equipment is easily burned, resulting in damage to the equipment, affecting the normal use of the equipment, and reducing the service life of the equipment.

[0004] However, the liquid cooling frame in patent authorization number CN 217124575 U is installed and fixed on the outside of the gun head usually with multiple screws, so it is necessary to fix multiple screws one by one, which makes assembly inconvenient and affects the installation efficiency. Therefore, we propose a liquid-cooled charging gun with a cooling structure that is easy to assemble to solve the above-mentioned problems. Utility Model Content
