Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a charging pile with waterproof heat dissipation. Background Technology

[0002] Currently, with the rapid popularization of new energy vehicles, the stability and reliability of charging piles, as their core infrastructure, are of paramount importance. During operation, the power modules, control systems, and other electronic components inside charging piles generate a large amount of heat. If heat dissipation is not timely, the component temperature will become too high, which will affect charging efficiency, accelerate equipment aging, and even cause safety hazards.

[0003] Currently, the cooling solutions for charging piles in the industry mainly rely on forced air cooling, which uses an internal fan to drive external air to flow over heat sinks or component surfaces to achieve convective heat transfer. In addition, air cooling solutions require opening a large number of ventilation holes or configuring louvers on the cabinet to introduce air. While this is beneficial for heat dissipation, rainwater can easily enter the equipment through these channels, causing corrosion or short circuit risks to electronic components. In order to balance heat dissipation and protection, complex dustproof and waterproof structures are usually required, but this also hinders air circulation to varying degrees, creating a contradiction. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a charging pile with waterproof heat dissipation, which has the advantages of automatically switching to water cooling in rainy weather and having a semi-closed louvered waterproof design.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a charging pile housing and an operating door installed on the charging pile housing, wherein a charging gun holder for placing a charging gun is provided on the side end face of the charging pile housing, and an installation plate is fixed inside the charging pile housing, wherein louvers are provided on both side end faces of the charging pile housing, and a plurality of louver strips are provided inside the louvers, and a water cooling component is also provided inside the charging pile housing. The water-cooling assembly includes a protective box, a water storage tank, a water collection cylinder, and a heat exchange pipe. The protective box is located inside the outer shell of the charging pile. The water storage tank is located inside the protective box and slides within the protective box. The water collection cylinder is located on the top of the outer shell of the charging pile. The heat exchange pipe is fixedly installed on the mounting plate to provide water-cooled heat exchange. The heat exchange pipe connects the water collection cylinder and the water storage tank.

[0006] Preferably, at least two support springs are fixed to the bottom of the water storage tank, and a drain outlet is fixed to the rear end face of the water storage tank, the drain outlet being connected to the interior of the water storage tank.

[0007] Preferably, one end of the heat exchange tube is fixedly installed on the water collection cylinder and the other end is fixedly installed on the protective box. The part of the heat exchange tube between the protective box and the water storage tank is a corrugated pipe, which is fixed together with the entire heat exchange tube, so that the entire water collection cylinder, the heat exchange tube and the water storage tank are isolated from the inside of the charging pile shell.

[0008] Preferably, the top edge of the charging pile housing extends upward to form a water collection trough, the water collection cylinder is located in the middle of the water collection trough, the part of the water collection cylinder inside the water collection trough is provided with several filter holes, and the top of the water collection cylinder is in a sealed or semi-sealed state.

[0009] Preferably, the heat exchange tubes are arranged in an S-shape from top to bottom on the mounting plate and are evenly distributed.

[0010] Preferably, the louvered strip includes two types: a fixed plate and a movable plate. The fixed plate is fixedly installed, and the movable plate is movably installed. The two types are alternately arranged. At the same time, part of the fixed plate extends outward, and part of the movable plate extends inward, so that the fixed plate and the movable plate are staggered in the vertical plane. The movable plate is fixed with sliding pins and rotating shafts on both ends, wherein the rotating shafts are rotatably mounted on the inner wall of the louvers of the charging pile housing.

[0011] Preferably, a sliding frame is slidably provided inside the outer shell of the charging pile. The sliding frame is located at two louvered windows, and a plurality of sliding grooves are opened inside the sliding frame. The sliding pin and the sliding groove are slidably engaged.

[0012] Preferably, a synchronous connecting rod is also fixedly installed at the bottom of the sliding frame. The synchronous connecting rod is L-shaped, and its other end is fixedly installed on the water storage tank, sliding along with the water storage tank.

[0013] Compared with the prior art, this utility model provides a charging pile with waterproof heat dissipation, which has the following beneficial effects: 1. This waterproof and heat-dissipating charging pile can collect rainwater on rainy days through the water-cooling components. The water-cooled components can then be used to circulate heat through the heat exchange pipes to cool the electronic components inside the charging pile. Water cooling is generally more efficient than air cooling, thus increasing the overall cooling efficiency of the charging pile.

[0014] 2. This waterproof and heat-dissipating charging pile uses a water-cooling component to cool the inside of the charging pile shell. At the same time, through the linkage of the water storage tank, most of the louvered channels are closed, leaving only a small channel open. At this time, it is difficult for rainwater to enter the charging pile shell through the small channel, so it can effectively achieve the effect of rain protection. The entire charging pile shell is mainly cooled by water cooling, with air cooling as an auxiliary, so that the overall cooling effect is no less than that of full air cooling.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-7As shown, the charging pile includes a charging pile housing 10 and an operation door 11 installed on the charging pile housing 10. A charging gun holder 102 for placing a charging gun is provided on the side end face of the charging pile housing, and a mounting plate 101 is fixed inside the charging pile housing 10. The mounting plate 101 is provided with several through holes, which divide the internal space of the charging pile housing 10 into two parts. The outer side of the mounting plate 101 can be used to install various electronic components, and the inner side is provided with airflow channels such as fans for heat dissipation inside the charging pile housing 10. Louvers are provided on both end faces of the charging pile housing 10, and several louver strips are provided inside the louvers. A water cooling component is also provided inside the charging pile housing 10.

[0019] The louvers include two types: a fixed plate 20 and a movable plate 21. The fixed plate 20 is fixedly installed, while the movable plate 21 is movably installed, and the two types are alternately arranged. A portion of the fixed plate 20 extends outward, and a portion of the movable plate 21 extends inward, causing the fixed plate 20 and movable plate 21 to be staggered in the vertical plane. Sliding pins 212 and a rotating shaft 211 are fixed to both end faces of the movable plate 21. The rotating shaft 211 is rotatably installed on the inner wall of the louvers of the charging pile housing 10, allowing the movable plate 21 to rotate around the rotating shaft 211. A sliding frame 22 is slidably installed inside the charging pile housing 10, located at the two louvered openings. A limiting structure is provided inside the charging pile housing 10 to restrict the sliding direction of the sliding frame 22, ensuring that the sliding frame 22 can only slide up and down. The interior has several sliding grooves, and the sliding pin 212 slides in the grooves. When the sliding frame 22 drives the movable plate 21 to rotate, the sliding pin 212 moves in an arc, thus preventing the sliding pin 212 from getting stuck. The movable plate 21 is located in the upper position between two adjacent fixed plates 20, that is, the height of the movable plate 21 from the lower fixed plate 20 is greater than the height of the movable plate 21 from the upper fixed plate 20. After the sliding frame 22 drives the movable plate 21 to rotate, the internal extension of the movable plate 21 abuts against the fixed plate 20 below it, thereby blocking the channel between the movable plate 21 and the lower fixed plate 20. This blocks the larger channel of the louver, leaving the smaller channel open. At this time, rainwater cannot easily enter the charging pile housing 10 through the smaller channel, thus effectively preventing rainwater from entering.

[0020] A synchronous link 23 is also fixedly installed at the bottom of the sliding frame 22. The synchronous link 23 is L-shaped, and its other end is fixedly installed on the water storage tank 31 below. It slides along with the water storage tank 31. Since the synchronous link 23 is fixedly connected to the water storage tank 31, it is slidably installed with the protective box 30.

[0021] The water-cooling assembly includes a protective box 30, a water storage tank 31, a water collection cylinder 32, and a heat exchange pipe 33. The protective box 30 is located inside the charging pile housing 10, the water storage tank 31 is located inside the protective box 30 and slides within the protective box 30, the water collection cylinder 32 is located on the top of the charging pile housing 10, and the heat exchange pipe 33 is fixedly installed on the mounting plate 101 to provide water-cooled heat exchange. Moreover, the heat exchange pipe 33 avoids the through holes of the mounting plate 101 so as not to affect normal air-cooled heat exchange. The heat exchange pipe 33 connects the water collection cylinder 32 and the water storage tank 31.

[0022] By setting up water-cooling components, rainwater can be collected on rainy days and circulated through the heat exchange tube 33 to achieve water-cooling cooling of the electronic components inside the charging pile housing 10. Water-cooling is generally more efficient than air-cooling, so it increases the overall cooling efficiency inside the charging pile housing 10.

[0023] At least two support springs 312 are fixed to the bottom of the water storage tank 31. The support springs 312 are used to support the weight of the water storage tank 31. Their elastic force is equal to or greater than the overall weight of the water storage tank 31, the synchronous connecting rod 23 and the sliding frame 22. Even if a small amount of water is stored in the water storage tank 31, the water storage tank 31 can still move, thereby closing part of the louvers. A drain outlet 311 is fixed to the rear end face of the water storage tank 31. The drain outlet 311 is connected to the inside of the water storage tank 31. The hole of the drain outlet 311 is small, and its outflow speed is less than the speed at which the water collection cylinder 32 collects rainwater, so that rainwater can be collected in the water storage tank 31 to provide weight. In light rain, there is no need to close the louvers. Therefore, even if the collection speed of the water collection cylinder 32 is less than the discharge speed of the drain outlet 311, there will be no significant impact. At this time, air cooling and water cooling can be carried out simultaneously to the maximum extent.

[0024] One end of the heat exchange tube 33 is fixedly installed on the water collection cylinder 32, and the other end is fixedly installed on the protective box 30. The part of the heat exchange tube 33 between the protective box 30 and the water storage tank 31 is a corrugated pipe, which is fixed together with the entire heat exchange tube 33. When the water storage tank 31 moves up and down, the corrugated pipe will extend or shorten to ensure the sealing of the entire heat exchange tube 33 while the water storage tank 31 moves. This isolates the entire water collection cylinder 32, the heat exchange tube 33 and the water storage tank 31 from the inside of the charging pile shell 10. During the entire process of rainwater collection, diversion and discharge, rainwater will not enter the inside of the charging pile shell 10. Since the water collection cylinder 32 and the protective box 30 are in a closed state, rainwater will not enter the inside of the charging pile shell 10, or excess water vapor will enter the inside of the charging pile shell 10.

[0025] After rain, while the water-cooling components cool the inside of the charging pile housing 10, the linkage of the water storage tank 31 closes most of the louver channels, leaving only a small channel open. At this time, it is difficult for rainwater to enter the charging pile housing 10 through the small channel, so it can effectively achieve the effect of rain protection. The entire charging pile housing 10 is mainly cooled by water cooling, with air cooling as an auxiliary method, so that the overall cooling effect is no less than that of full air cooling.

[0026] The top edge of the charging pile housing 10 extends upward to form a water collection tank 103. The water collection cylinder 32 is located in the middle of the water collection tank 103. The part of the water collection cylinder 32 inside the water collection tank 103 is provided with several filter holes. The top of the water collection cylinder 32 is sealed or semi-sealed. There is a gap at the rear edge of the water collection tank 103. When there is too much rainwater, it can flow to the rear through this gap. The heat exchange pipe 33 is arranged in an S-shape from top to bottom on the mounting plate 101 and is evenly distributed, so that the rainwater can flow downward automatically under its own gravity without the need for additional power equipment, saving energy consumption. Moreover, the whole process does not require additional power assistance and does not rely on additional power and detectors, which greatly saves costs.

[0027] Working Principle: During use, in sunny weather, the water storage tank 31 contains no rainwater. Supported by the spring 312, the water storage tank 31 is always kept open by the synchronous connecting rod 23 and the sliding frame 22, ensuring maximum ventilation inside the charging pile casing 10 for air cooling. In rainy weather, rainwater is collected by the water collection tank 103 and enters the water collection cylinder 32. It is then guided through the heat exchange pipe 33, which is attached to the surface of the mounting plate 101. Through heat exchange, it absorbs the heat generated by the electronic components on or outside the mounting plate 101, allowing the rainwater to flow into the water storage tank 31, increasing... The weight of the water tank 31 causes it to compress the support spring 312 and move downwards. The movement of the water tank 31 drives the synchronous connecting rod 23 to move downwards, which in turn causes the sliding frames 22 on both sides to simultaneously rotate the movable plate 21 downwards until the movable plate 21 abuts against one end of the fixed plate 20. This closes most of the louver channel, leaving only a small channel to ensure ventilation inside the charging pile housing 10. This effectively prevents rainwater from entering, especially in heavy rain, and prevents rainwater splashing. With the louver mostly closed, the rainwater is used for water cooling, achieving a rainproof effect without affecting the overall cooling effect inside the charging pile housing 10.

[0028] After the rain stops, some rainwater is still stored in the water tank 31, and then slowly discharged through the drain outlet 311. This allows for a certain period of water cooling, and the water is gradually emptied through the drain outlet 311. At this time, the support spring 312 returns to its elasticity, which can drive the water tank 31 and the synchronous connecting rod 23 to move upward. The sliding frame 22 can then open the movable plate 21, putting the louvers in the maximum ventilation state and starting air cooling. The above process is repeated when it rains again.

[0029] In summary, this waterproof and heat-dissipating charging pile, through the water-cooling components, can collect rainwater on rainy days and circulate it through the heat exchange pipe 33 to cool the electronic components inside the charging pile shell 10. Water cooling is generally more efficient than air cooling, thus increasing the overall cooling efficiency inside the charging pile shell 10. While the water-cooling components are cooling the inside of the charging pile shell 10, the linkage of the water tank 31 closes most of the louver channels, leaving only a small channel open. At this time, it is difficult for rainwater to enter the charging pile shell 10 through the small channel, thus effectively achieving a rainproof effect. The entire charging pile shell 10 is mainly cooled by water cooling, with air cooling as an auxiliary method, so that the overall cooling effect is no less than that of full air cooling.
