Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a heat dissipation type charging pile. Background Art

[0002] Charging piles refer to charging equipment that provides charging services for electric vehicles. Charging piles can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They 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 gun through a cable for charging electric vehicles.

[0003] During actual use, a large amount of heat is easily generated inside the charging pile, and high temperature easily leads to aging and failure of connecting cables and components. Therefore, charging piles are generally equipped with heat dissipation structures.

[0004] However, the heat dissipation structure of the commonly used charging piles is prone to absorb impurities in the air into the charging piles when exchanging air with the outside world. In particular, charging piles are generally set up in public areas with poor air quality. When ventilating and dissipating heat, a large amount of dusty air will enter the heat dissipation port of the charging piles, which can easily cause dust accumulation inside the charging piles, further affecting the normal use of the charging piles. Utility Model Content

[0005] The utility model aims to provide a heat dissipation type charging pile, which is used to solve the problem that dust is easily accumulated inside the current charging pile when ventilation heat dissipation is adopted.

[0007] Preferably, the front and rear walls of the inner cavity of the heat exchange plate-shaped shell are provided with a plurality of fins extending in the vertical direction.

[0008] Preferably, arc-shaped plates are respectively provided on the front and rear sides of the top end of the heat exchange plate-shaped shell, and the arc-shaped plates are fitted and fixed to the bottom of the air distribution cylinder at positions corresponding to the front and rear sides of the rectangular air outlet.

[0009] Preferably, connecting flanges are respectively provided at both ends of the air distribution cylinder, and the connecting flanges are respectively fixed to the top of the middle part of the two side walls of the inner cavity of the charging pile body by screws.

[0010] Preferably, a mesh plate 1 is provided at the inner end of the inner cavity of the connecting sleeve, the air outlet box body includes a columnar shell whose inner end is threadedly sleeved with the connecting sleeve and a mesh plate 2 provided at the outer end of the inner cavity of the columnar shell, and the filter mesh column is sleeved in the inner cavity of the columnar shell.

[0011] Preferably, the fan is a small axial flow fan.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model relates to a heat dissipation charging pile which can absorb the heat generated by the components when they are working through the heat exchange plate-shaped shell. This part of the absorbed heat is directly discharged to the outside of the charging pile body after being absorbed by the gas flowing in the inner cavity of the heat exchange plate-shaped shell. This part of the flowing gas does not directly flow through the inner cavity of the charging pile body, so dust will not accumulate inside the charging pile body; another part of the air in the air distribution cylinder is filtered by the air outlet box body and discharged to the inner cavity of the charging pile body. This part of the air further absorbs the heat in the inner cavity of the charging pile body and is discharged. This part of the flowing air is filtered through the filter column, avoiding the accumulation of dust in the inner cavity of the charging pile body. In addition, the filter column is easy to disassemble and replace, thereby improving the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: a heat dissipation charging pile, comprising a charging pile body 1, and a grille mesh 2 is covered at an opening near the bottom of the side wall of the charging pile body 1.

[0026] The fan 3 is mounted on the top of one side wall of the charging pile body 1 , wherein the fan 3 is a small axial flow fan.

[0027] One end of the air distribution cylinder 4 is connected to the air outlet end of the fan 3. The bottom end of the air distribution cylinder 4 is provided with a plurality of rectangular air outlet holes 4.2 along its axial direction. The front and rear walls of the air distribution cylinder 4 are provided with a plurality of connecting sleeves 4.3 along its axial direction. Among them, the two ends of the air distribution cylinder 4 are provided with connecting flanges 4.1, which are respectively fixed to the top of the middle of the two side walls of the inner cavity of the charging pile body 1 with screws. The inner end of the inner cavity of the connecting sleeve 4.3 is provided with a mesh plate 4.4.

[0028] The air outlet box body 5 is detachably sleeved on the connecting sleeve 4.3, and a filter screen column 5.3 is installed in the inner cavity of the air outlet box body 5. The air outlet box body 5 includes a columnar housing 5.1 whose inner end is threadedly sleeved with the connecting sleeve 4.3 and a mesh plate 2 5.2 arranged at the outer end of the inner cavity of the columnar housing 5.1, and the filter screen column 5.3 is sleeved in the inner cavity of the columnar housing 5.1. That is, the columnar housing 5.1 can be easily disassembled and assembled with the connecting sleeve 4.3, so as to facilitate the replacement or cleaning of the filter screen column 5.3.

[0029] The top end of the heat exchange plate-shaped shell 6 is connected to the position of the bottom of the air distribution cylinder 4 corresponding to the rectangular air outlet 4.2, and the front wall of the heat exchange plate-shaped shell 6 is used to install electrical components, that is, the electrical components are directly installed on the front wall of the heat exchange plate-shaped shell 6 by screws. The bottom end of one side of the heat exchange plate-shaped shell 6 is connected to an air outlet pipe 6.3 whose outlet end is against the inner wall of the grille 2. Among them, in order to improve the heat dissipation effect, the front and rear walls of the inner cavity of the heat exchange plate-shaped shell 6 are provided with a plurality of fins 6.1 extending vertically. The front and rear sides of the top of the heat exchange plate-shaped shell 6 are respectively provided with arc plates 6.2, which are fitted and fixed to the positions of the front and rear sides of the bottom of the air distribution cylinder 4 corresponding to the rectangular air outlet 4.2.

[0030] In summary, when in use, the fan 3 is turned on, and the fan 3 draws air from the outside of the charging pile body 1 and discharges the air into the inner cavity of the air distribution cylinder 4. Most of the air in the inner cavity of the air distribution cylinder 4 enters the inner cavity of the heat exchange plate-shaped shell 6 through the rectangular air outlet 4.2, and is discharged through the grille mesh 2 through the air outlet pipe 6.3. In this process, the air in the inner cavity of the heat exchange plate-shaped shell 6 absorbs the heat generated by the electrical components through the fins 6.1 and the outer wall of the heat exchange plate-shaped shell 6.

[0031] Another part of the air in the air distribution cylinder 4 enters the columnar housing 5.1 through the connecting sleeve 4.3, and enters the inner cavity of the charging pile body 1 after being filtered by the filter column 5.3, flows through the heating element in the inner cavity of the charging pile body 1, takes away the heat, and is finally discharged from the grille 2 to achieve the effect of heat dissipation.

[0032] Among them, the air flowing through the inner cavity of the heat exchange plate-shaped shell 6 does not directly contact the inner cavity components of the charging pile body 1, so that dust will not accumulate on the components inside the charging pile body 1; the air discharged from the air outlet box body 5 is filtered through the filter column 5.3, so that dust will not accumulate in the inner cavity of the charging pile body 1.
