Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile heat dissipation structure and a car charging pile. Background Art

[0002] The function of a 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 electric vehicles.

[0003] Referring to the Chinese invention patent, the publication number is: CN 116788079 B, and the name is: A charging pile heat dissipation structure and a car charging pile. This application completes the heat dissipation of the internal structure of the charging pile through an air supply component, and by setting two air supply components, wind can be input into the charging pile from both sides to speed up the heat dissipation speed and shorten the heat dissipation time. By setting the cover plate, when the charging pile does not need to dissipate heat, the cover plate covers its heat dissipation port to avoid damage to the internal structure of the charging pile. In addition, the support frame pulls the cover plate up through the traction member to avoid the inability to complete the air supply operation into the charging pile due to the obstruction of the cover plate.

[0004] However, in actual use, the above and similar technical solutions still have some problems:

[0005] 1. In the operation process of the cooling system, although directly introducing the external ambient air as the cooling medium can realize an effective heat exchange process, this practice also brings the risk of humid air (i.e. air with a high moisture content) penetrating into the cooling system. In the long run, the accumulation of humid air may cause corrosion and electrical short circuit problems to the internal components of the controller, which in turn poses a significant threat to the service life of the controller. In addition, the traditional fixed-direction fan blowing mode has limitations in terms of the comprehensiveness and efficiency of heat exchange, making it difficult to achieve the optimal state of the cooling system performance, limiting the improvement of the overall cooling effect;

[0006] 2. The charging column lacks the necessary protective mechanism at the design level, which makes it very easy to be eroded by rain for a long time when exposed in the outdoor environment, which may cause physical damage or electrical system failure. At the same time, due to the lack of dust prevention measures, dust is easy to accumulate on the surface of the charging column, which not only affects the normal operation and heat dissipation performance of the equipment, but also may pose a potential threat to the long-term stable operation of the equipment. More seriously, in emergency situations such as fire, due to the lack of effective fire blocking structure design of the charging column, the flame and heat may spread rapidly to adjacent areas, thereby aggravating the severity of the disaster and posing a major risk to public safety;

[0007] 3. As an important component of external charging equipment, the charging cable has a relatively fragile physical structure and is easily damaged by various external factors. Especially during long-term and frequent use, the charging cable frequently contacts the ground and is dragged. This physical friction greatly accelerates its aging and damage process, which not only affects the charging efficiency and safety of the charging cable, but also may increase the risk of short-circuit failure due to line damage, posing a potential threat to the safety and stability of the charging process. Therefore, it is particularly important to strengthen the physical protection and durability design of the charging cable. Summary of the invention
