It includes a door panel, which is installed on the charging pile to cover the ventilation openings. The door panel has heat dissipation holes for ventilation and heat dissipation inside the charging pile. A louvered cover is detachably installed on the side of the door panel facing the inside of the charging pile. A through groove is formed within the louvered cover, which covers the heat dissipation holes. A heat dissipation plate is detachably installed within the through groove, and a flow channel is formed within the heat dissipation plate. The charging pile can achieve air circulation through the flow channel and the heat dissipation holes. A drainage slope is inclined towards the door panel on the inner circumference of the through groove, and the vertical projection of the drainage slope on the door panel intersects with the heat dissipation holes.

The rainwater can flow out through the heat dissipation before overflowing the drainage slope, thereby preventing rainwater from entering the charging pile.

Description

Technical Field

[0001] This application relates to the field of charging pile technology, and in particular to a waterproof heat dissipation louver structure for a charging pile and a charging pile. Background Technology

[0002] With the rapid development of new energy vehicles, charging piles, as core infrastructure, have become a key focus in terms of reliability, safety, and durability. Charging piles generate a significant amount of heat during charging, necessitating ventilation openings for heat dissipation. Because outdoor charging piles are constantly exposed to complex environments (such as rain, dust, and salt spray), ventilation louvers are typically installed at the ventilation openings for waterproofing and dustproofing. However, the waterproofing effect of these ventilation louvers is often poor, making it difficult for rainwater to drain. Prolonged use can easily damage the electrical components inside the charging pile, affecting its lifespan. Furthermore, water ingress into the charging pile can pose safety hazards and potentially lead to accidents. Summary of the Invention

[0003] The purpose of this application is to provide a waterproof and heat dissipation louver structure for a charging pile and a charging pile in general, so as to solve the problem of poor waterproof and dustproof effect at the ventilation opening of the charging pile in the prior art.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] On the one hand, this application provides a waterproof and heat-dissipating louvered structure for a charging pile and a charging pile, including:

[0006] A door panel, which is mounted on the charging station to cover the ventilation opening, and the door panel has heat dissipation holes;

[0007] The louver includes a louver cover and a heat dissipation plate. The louver cover is detachably installed on the door panel and has a through groove inside. The bottom side of the inner circumference of the through groove has a drainage slope that slopes towards one side of the door panel. The vertical projection of the drainage slope on the door panel intersects with the heat dissipation hole. The heat dissipation plate is detachably installed in the through groove and has a flow channel formed inside the heat dissipation plate.

[0008] In this design, a door panel is installed on the charging pile to cover the column ventilation opening. The door panel has heat dissipation holes for ventilation and heat dissipation inside the charging pile. A louvered cover is detachably installed on the side of the door panel facing the inside of the charging pile. A through groove is formed inside the louvered cover, which covers the heat dissipation holes. A heat dissipation plate is detachably installed inside the through groove, and a flow channel is formed within the heat dissipation plate. The charging pile can achieve air circulation and heat dissipation through the flow channel and the heat dissipation holes. Furthermore, a drainage slope is sloping towards the door panel on the inner bottom side of the through groove. The vertical projection of the drainage slope on the door panel intersects with the heat dissipation holes. After rainwater enters the louvered area through the heat dissipation holes, it comes into contact with the heat dissipation plate and flows down along the heat dissipation plate or the inner wall of the door panel between the door panel and the drainage slope. Because the vertical projection of the drainage slope on the door panel intersects with the heat dissipation holes, rainwater can flow out through the heat dissipation holes before overflowing the drainage slope, thereby preventing rainwater from entering the charging pile and achieving active drainage.

[0009] Optionally, the heat sink includes:

[0010] The first heat sink is detachably installed in the through slot. The first heat sink has a frame structure and has multiple vertically spaced blades inside.

[0011] The second heat sink is embedded in the first heat sink, which is a frame structure with multiple vertically spaced blades inside.

[0012] The first and second louvers are Z-shaped louvers, which are staggered. Adjacent first and second louvers define a flow channel, and the projection of the second louver in the depth direction of the channel intersects with the first louver.

[0013] In this design, the 100th and 200th louvers are Z-shaped. Rainwater hitting the Z-shaped louvers will flow downwards along their inclined surfaces between the entry panel and the drainage slope. The 100th and 200th louvers are staggered, with adjacent 100th and 200th louvers defining a flow channel. The projection of the 200th louver in the channel depth direction intersects with the 100th louver. This design ensures that the heat dissipation plate, while providing heat dissipation capacity, allows the 100th and 200th louvers to completely cover the channel in the channel depth direction, thus ensuring that rainwater entering the louvers through the ventilation holes can completely hit either the 100th or 200th louver.

[0014] Optionally, the outer periphery of the louver cover has an outer frame, and a sealing gasket is sandwiched between the outer frame and the door panel.

[0015] A sealing gasket is sandwiched between the outer frame and the door panel to prevent rainwater between the door panel and the drainage slope from flowing into the charging station through the gap between the louvered cover and the door panel.

[0016] Optionally, the louvers are provided with a primary filter and a pressure plate stacked sequentially on the side opposite to the heat sink plate. The pressure plate has a frame structure and a wire mesh is provided inside the pressure plate.

[0017] Optionally, the louvered outer cover has an inner frame, and the pressure plate has pins on both sides at the bottom to be inserted into the inner frame facing the heat sink. The inner frame and the pressure plate are respectively provided with mounting holes, and the pressure plate and the inner frame are connected by bolts.

[0018] This design incorporates a primary filter on the side of the louvers facing away from the heat sink. The filter is pressed against the louvers by steel wires in a pressure plate. This primary filter filters the air entering the charging station, preventing dust from entering.

[0019] On the other hand, this application provides a charging pile, including any of the above-described waterproof and heat-dissipating louvered structures for charging piles.

[0020] Compared with existing technologies, the beneficial effects achieved by this application are as follows: This application ensures air circulation within the charging pile by setting heat dissipation holes on the door panel and forming a flow channel within the heat dissipation plate, thereby achieving heat dissipation of the charging pile. A drainage slope sloping towards the door panel is located on the inner circumference of the channel bottom side, and the vertical projection of the drainage slope on the door panel intersects with the heat dissipation holes. After rainwater enters the louvers through the heat dissipation holes, it can contact the heat dissipation plate and flow down along the heat dissipation plate or the inner wall of the door panel between the door panel and the drainage slope. The intersection of the vertical projection of the drainage slope on the door panel with the heat dissipation holes allows rainwater to flow out through the heat dissipation plate before overflowing the drainage slope. This prevents rainwater from entering the charging pile, achieving active drainage and preventing rainwater from entering the charging pile through the vents and causing damage to the electrical components inside the charging pile.

Detailed Implementation

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0035] Example 1

[0036] This embodiment describes a waterproof and heat-dissipating louvered structure for a charging pile, referencing... Figures 1 to 3The waterproof and heat-dissipating louvered structure of the charging pile in this embodiment includes: a door panel 1. The door panel 1 is fixed to the inner wall of the charging pile by foam strips, and the door panel 1 can completely cover the ventilation opening. The door panel 1 has heat dissipation holes 11, which are multiple hexagonal holes, for ventilation and heat dissipation inside the charging pile. A louvered cover 21 is detachably installed on the side of the door panel 1 facing the inside of the charging pile. A through groove is formed in the louvered cover 21, which can cover the heat dissipation holes 11. A heat dissipation plate is detachably installed in the through groove, and a flow channel is formed in the heat dissipation plate. The charging pile can achieve air circulation and heat dissipation through the flow channel and the heat dissipation holes 11. Further, a drainage slope 211 inclined towards the door panel 1 is provided on the inner circumference bottom side of the through groove. The obtuse angle between the drainage slope 211 and the horizontal plane is 130°, and its vertical projection on the door panel 1 intersects with the heat dissipation holes 11. After rainwater enters the louver 2 through the heat dissipation hole 11, it comes into contact with the heat dissipation plate and flows down along the heat dissipation plate or the inner wall of the door panel 1 between the door panel 1 and the drainage slope 211. Because the vertical projection of the drainage slope 211 on the door panel 1 intersects with the heat dissipation hole 11, rainwater can flow out through the heat dissipation hole 11 before overflowing the drainage slope 211, thereby preventing rainwater from entering the charging pile and achieving active drainage.

[0037] Further, refer to Figures 3 to 5 The heat dissipation plate includes a first heat dissipation plate 22 and a second heat dissipation plate 23. The first heat dissipation plate 22 is detachably installed within a through groove. The first heat dissipation plate 22 has a frame structure with several drainage holes 222 at its bottom and multiple vertically spaced first louvers 221 inside. The second heat dissipation plate 23 is embedded within the first heat dissipation plate 22. The first heat dissipation plate 22 also has a frame structure and multiple vertically spaced second louvers 231 inside. Further, the first louvers 221 and second louvers 231 are Z-shaped louvers with a bending angle of 130°, and their surfaces are coated with an epoxy resin anti-rust layer for weather resistance. Rainwater hitting the Z-shaped louvers will flow downwards along their inclined surface between the entry panel 1 and the drainage slope 211. (Reference) Figure 6 and Figure 7 The first 100th blade 221 and the second 100th blade 231 are staggered, and adjacent first 100th blades 221 and second 100th blades 231 define a flow channel, thereby achieving heat dissipation inside the charging pile. The projection of the second 100th blade 231 in the depth direction of the slot intersects with the first 100th blade 221, so that while the heat dissipation plate has heat dissipation capacity, the first 100th blades 221 and second 100th blades 231 can completely cover the slot in the depth direction of the slot, thereby ensuring that rainwater entering the louver 2 through the heat dissipation hole 11 can completely hit the first 100th blade 221 or the second 100th blade 231, preventing rainwater from entering the charging pile.

[0038] To prevent rainwater between the door panel 1 and the drainage slope 211 from flowing into the charging station through the gap between the louver cover 21 and the door panel 1, in this embodiment, the louver cover 21 has an outer frame 212 on its outer periphery, and a sealing gasket 3 is sandwiched between the outer frame 212 and the door panel 1. Specifically, a number of rivets 12 are provided on the side of the door panel 1 facing the louver 2, and the door panel 1, the sealing gasket 3, and the outer frame 212 are riveted together. In this embodiment, the sealing gasket 3 is made of silicone material, which has the advantages of weather resistance and good sealing performance.

[0039] Example 2

[0040] Based on the same inventive concept as Embodiment 1, refer to Figure 1 , Figure 8 and Figure 9 To prevent dust from entering the charging pile with airflow, in this embodiment, a primary filter cotton 4 and a pressure plate 5 are stacked sequentially on the side of the louvers 2 facing away from the heat sink plate. The pressure plate 5 is a frame structure, and a wire mesh 51 is installed inside the pressure plate 5. The primary filter cotton 4 filters the air entering the charging pile, preventing dust from entering. The wire mesh 51 is made of stainless steel, with dense and uniform mesh openings that are not easily broken. The wire mesh 51 is fixed to the inner wall of the pressure plate 5 by spot welding at uniform intervals around its perimeter, covering the entire ventilation area. The primary filter cotton 4 is then pressed and fixed by the wire mesh 51.

[0041] The primary filter cotton (type 4) is used as a filter material and needs to be replaced after a certain period of use. (Reference) Figure 10 and Figure 11 To facilitate the replacement of the primary filter cotton 4, in this embodiment, the pressure plate 5 is detachably mounted on the louvered outer cover 21. Specifically, the inner periphery of the louvered outer cover 21 has an inner frame 213, and the pressure plate 5 has pins 52 on both sides at its bottom to accommodate insertion into the inner frame 213 facing the heat dissipation plate. The inner frame 213 and the pressure plate 5 are respectively provided with mounting holes, and the pressure plate 5 and the inner frame 213 are connected by bolts. The pressure plate 5 can be easily disassembled or installed using the bolts and pins 52.
