Description

Technical Field

[0001] The present invention relates to the technical field of new energy charging piles, and in particular to a dynamic split-type AC charging pile. Background Art

[0002] Compared to integrated DC charging piles, split AC charging piles consist of separate components, including the charger, charging plug, and display screen. The charger is typically housed in a separate cabinet. Integrated DC charging piles integrate the DC charger, control system, and connection components into a single device, resulting in a compact design that facilitates installation and maintenance.

[0003] According to Chinese patent publication number CN108579349A, published on September 28, 2018, a dry air generator for dehumidifying circuit boards in charging piles is disclosed, comprising an air filter, a fan, and a semiconductor refrigeration module; the fan is connected to the upper end of a cold-end pipe, and the air filter is connected to the fan; the lower end of the cold-end pipe is connected to the lower end of the hot-end pipe to form a U-shaped air duct; a drain outlet is provided at the bottom of the U-shaped air duct; and the semiconductor refrigeration module is fixed between the cold-end pipe and the hot-end pipe.

[0004] In the prior art, including the aforementioned patents, when using split-type AC charging piles, the circuit board inside the AC charging pile generates heat during vehicle charging. When the charging pile housing is lower in temperature than the circuit board, creating a condensation temperature difference, condensation forms inside the charging pile housing. Especially in low-temperature conditions, the formation of condensation can create a risk of short circuits between the PIN pins of the circuit board signal terminals and the adjacent pin solder pins. Therefore, the semiconductor refrigeration module described in the aforementioned patents is exposed to relatively low or high humidity temperatures to form condensation in advance and naturally fall and discharge, thereby reducing the impact of moisture inside the charging pile and the generation of condensation on the circuit board. However, in actual use, in some relatively low-temperature environments, such as -10 degrees Celsius to 0 degrees Celsius, condensation is difficult to form when the semiconductor refrigeration module is exposed to low temperatures. At the same time, when some condensation droplets are slowly discharged through the drain outlet, due to the slow flow rate of the liquid and the large surface area of the droplets, they are easily cooled below the dew point due to prolonged exposure to cold air, resulting in condensation. When the droplets in the drain outlet gradually condense and accumulate, they will become clogged, leading to problems such as condensation backflow or condensation inside the charging pile, thus affecting the use of the charging pile. Summary of the Invention

[0005] The purpose of the present invention is to provide a dynamic split AC charging pile, which accumulates a certain amount of condensation water in the charging pile and then discharges the condensation in a short time, thereby reducing the problem of ice and blockage at the drainage outlet on the charging pile.

[0006] In order to achieve the above object, the present invention provides the following technical solution: a dynamic split AC charging pile, comprising a functional box installed on a pile body, wherein the functional box includes: A heat conducting plate on which the circuit board is fixedly mounted has fins fixedly arranged on one side thereof which are distributed at equal intervals and along a vertical pattern; Condensation plates inserted between the fins and maintaining a certain distance from them; A trough box is fixed on the heat conducting plate to receive condensation, and a siphon channel is provided in the trough box at a predetermined height from the bottom.

[0011] Preferably, the vibration plate fixedly mounted on the elastic plate contacts the guide member slidably mounted on the liquid outlet of the siphon channel, and the two are in a vertical relationship; In the default state, the vibration plate is in a horizontal state and is distributed in parallel with the extension plate fixedly installed at the bottom of the trough box.

[0012] Preferably, the air shield box is further included and is located below the trough box. The air shield box is structurally divided into an upper inclined portion and a horizontal portion, and a predetermined distance is maintained between the horizontal portion and the bottom of the trough box to form a second air duct. The wind shield box includes a first air duct distributed adjacent to the heat conducting plate, and the first air duct is located at a high position on the upper slope.

[0013] Preferably, the functional box includes a drain port at the bottom, and air leakage ports on the inner wall of the upper inclined portion are distributed toward the drain port.

[0014] Preferably, a curved plate is provided on the elastic plate, and a curved guide plate plugged into the bottom end of the curved plate moves relative to the windshield box.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-10 As shown, a dynamic split AC charging pile includes a function box 11 installed on a pile body 1, and the function box 11 includes: The heat conducting plate 2 is fixedly mounted with the circuit board 22, and one side of the heat conducting plate 2 is fixedly provided with fins 3 that are evenly spaced and distributed along the vertical line; A condensation plate 43 inserted between the fins 3 and maintaining a certain distance therefrom; A trough box 21 is fixed on the heat conducting plate 2 to receive condensation, and a siphon channel 24 is defined therein at a predetermined height from the bottom.

[0022] Specifically, the heat conducting plate 2 is fixedly mounted within the function box 11 using screws, and the slot box 21 is welded to the heat conducting plate 2. The circuit board 22 is also fixedly mounted to the heat conducting plate 2 using screws, and the fins 3 are fixedly welded to the heat conducting plate 2 on the side opposite the circuit board 22. The heat conducting plate 2 is made of an aluminum alloy plate, and the slot box 21 is made of an aluminum alloy box. Multiple condensation plates 43 are located between the fins 3 and maintain a certain distance from the heat conducting plate 2. The condensation plates 43 extend through the housing of the function box 11 to the outside of the function box 11. The power semiconductor devices on the circuit board 22, such as IGBTs and MOSFETs, generate a large amount of heat when controlling AC power conversion, rectification, and frequency conversion. The rectifier bridge and frequency conversion circuit on the circuit board 22 also generate heat when converting AC power to DC or adjusting AC parameters. The distance between the fins 3 and the condensation plates 43 is 1mm-3mm.

[0023] Furthermore, by utilizing the heat conducting plate 2 to absorb the heat generated by these components and transferring it to the fins 3, the fins 3 heat the surrounding air, while the condensation plate 43 contacts the air outside the functional box 11. When the environment is low temperature, the hot and humid air around the fins 3, which is at a temperature relatively low to the condensation plate 43, forms condensation when it contacts the condensation plate 43. Therefore, the fins 3 improve heat dissipation to the circuit board 22 while also heating the air, thereby promoting the formation of condensation on the condensation plate 43. The formed condensation then falls along the condensation plate 43 into the trough box 21 for collection. Therefore, in a low-temperature environment, the heat of the circuit board 22 itself is utilized to accelerate the formation and collection of condensation in the functional box 11, thereby reducing the impact of humidity in the functional box 11 on the circuit board 22. This also solves the problem of difficulty in forming condensation at low temperatures in some systems that only use semiconductor refrigeration modules.

[0024] Furthermore, since part of the heat on the heat conducting plate 2 will be transferred to the condensation liquid in the tank box 21, thereby preventing condensation, when the condensation liquid collected in the tank box 21 rises and reaches the siphon height, the siphon effect is used to continuously discharge the collected condensation in a short time, thereby avoiding the problem of slow and continuous condensation drainage, which is easy to freeze and clog.

[0025] Furthermore, the condensation plate 43 is an aluminum alloy plate.

[0026] In the above technical solution, the heat of the circuit board 22 itself is utilized to heat the fins 3 on the heat conducting plate 2, and then the fins 3 heat the low-temperature humid air around it. The heated humid air and the condensation plate 43 form a temperature difference to form condensation on the condensation plate 43. The condensation is then collected in the tank box 21 and when it reaches a certain amount, it is siphoned and continuously discharged along the siphon channel 24, thereby solving the problem that condensation is difficult to form at low temperatures relying solely on the semiconductor refrigeration module, and the problem that the liquid is continuously and slowly drained during drainage to cause ice blockage.

[0027] As an embodiment further provided by the present invention, a centrifugal fan 44 is fixedly provided on the function box 11 , with the air outlet distributed toward the condensation plate 43 .

[0028] Specifically, the centrifugal fan 44 is fixedly installed in the function box 11 with screws, and the centrifugal fan 44 is located above the condensation plate 43. By making the function box 11 openable and closable, when the external temperature is high, by opening the window provided on the side of the air inlet of the centrifugal fan 44 on the function box 11, the centrifugal fan 44 can draw in external air to ventilate and cool the function box 11. When the external humidity is high or the temperature is low, the window is closed, and the centrifugal fan 44 performs internal circulation dehumidification in the function box 11, as well as a certain insulation effect. This reduces the humidity in the function box 11 and the effects of excessively low temperatures on the formation of condensation. The window can be opened and closed by manually placing and removing the baffle; or by a motor driving the baffle to flip; or by driving the window to open as known to those skilled in the art.

[0029] As another embodiment provided by the present invention, the condensation plate 43 vibrates to move the condensation between it and the main fin 3 .

[0030] Specifically, the vibration of the condensation plate 43 causes the smaller condensation on the condensation plate 43 to gather due to the vibration, and the gathered condensation forms larger water droplets that fall quickly. Figure 6 As shown, the vibration of the condensation plate 43 accelerates the accumulation of condensation into droplets, exposing more of the surface of the condensation plate 43 for subsequent moisture to better contact the condensation plate 43 and form new condensation. This prevents small, locally distributed condensation from occupying more of the outer surface of the condensation plate 43, which would reduce the efficiency of moisture contact with the condensation plate 43. Simultaneously, the vibration of the condensation plate 43 causes the main fins 3 to squeeze the condensation on the condensation plate 43, collecting it. Condensation can also accumulate on the main fins 3, cooling them. Furthermore, if dust is carried in the air passing between the main fins 3 and the condensation plate 43, condensation can absorb some of the dust. When the dust adheres to the main fins 3 and the condensation plate 43, the condensation collects and falls, and some of it is transferred to the main fins 3 for collection and fall. The falling condensation can then be used to clean the dust on the main fins 3 and the condensation plate 43.

[0031] The condensation plates 43 may be vibrated by an ultrasonic generator, or by a vibration motor coupled to connecting rods connected to the condensation plates 43, or by any other method known to those skilled in the art to drive the condensation plates 43 to vibrate.

[0032] As another embodiment provided by the present invention, shielding plates 31 arranged in a linear array and shielding part of the air duct of the centrifugal fan 44 are fixedly installed on the top of every two fins 3.

[0033] Specifically, the fins 3 can be fixed on the inner wall of the functional box 11 by screws, and multiple baffles 31 are welded to the tops of multiple fins 3 in sequence. The baffles 31 are used to close the gaps directly between some of the fins 3. At this time, a wide mouth is formed between each two baffles 31 at the top of the fin 3, and the gap between the two fins 3 is narrower than the wide mouth, thus forming a Venturi structure. At this time, the baffles 31 are used to increase the air flow rate between some of the fins 3, and then when the centrifugal fan 44 blows, it will drive the condensation plate 43 between the fins 3 to vibrate, and then use the vibration of the condensation plate 43 to increase the falling rate of the condensation, while accelerating the gathering of the condensation, and the surface of the vibrating condensation plate 43 is not easy to adhere to dust.

[0034] Another embodiment provided by the present invention further includes an elastic plate 4 fixedly connected to a plurality of condensation plates 43 , which is parallel to the heat conducting plate 2 .

[0035] Specifically, multiple condensation plates 43 are fixedly welded to the elastic plate 4. The top of the elastic plate 4 is screwed to the centrifugal fan 44, while the bottom of the elastic plate 4 is movable. By using the elastic plate 4 to enclose the condensation plates 43, the vibration generated by the operation of the centrifugal fan 44 is transmitted to the multiple condensation plates 43 through the elastic plate 4. At the same time, the airflow from the centrifugal fan 44 is restricted from flowing along the condensation plates 43 and fins 3. The airflow acting on the elastic plate 4 also causes the elastic plate 4 to vibrate. Therefore, the outer wall surface of the elastic plate 4 on the side of the heat conducting plate 2 also serves as the surface for condensation formation. The elastic plate 4 is an elastic stainless steel plate.

[0036] Further, such as Figure 5 and Figure 8 As shown, a curved plate 41 is fixedly welded to the bottom end of the elastic plate 4. When the weather is low temperature, the cold air outside or in the functional box 11 is blown between the condensation plate 43 and the fin 3 by the centrifugal fan 44, and then passes through the condensation plate 43 and the fin 3 to condense and remove dust to a certain extent. Then, when the blast air leaves the condensation plate 43 and the fin 3, it is blown into the trough box 21. At this time, the dust in the air is further absorbed by the liquid level in the trough box 21. At the same time, the trough box 21 is in a low position to achieve the deposition of dust in the blast air. Then, the blast air flows along the surface of the curved plate 41 so that the dehumidified and dust-removing air acts on the circuit board 22, thereby improving the service life of the circuit board 22.

[0037] As the best embodiment provided by the present invention, the vibration plate 42 fixedly mounted on the elastic plate 4 contacts the guide member 8 slidably mounted on the liquid outlet of the siphon channel 24, and the two are in a vertical relationship; In a default state, the vibration plate 42 is in a horizontal state and is distributed in parallel with the extension plate 25 fixedly installed at the bottom of the tank box 21 .

[0038] Specifically, the extension plate 25 is fixedly welded to the bottom of the trough box 21. A drain pipe 81 is fixedly connected to the bottom end of the guide member 8. The guide member 8 and drain pipe 81 are integral hard plastic tubes. A sealing rubber ring 23 is fixedly mounted on the outer wall of the trough box 21 on one side of the guide member 8. A shock-absorbing rubber pad 82 is glued to the outer wall of the drain pipe 81. The vibration plate 42 is fixedly welded to the elastic plate 4 and is located below the drain pipe 81 and affixed to the shock-absorbing rubber pad 82. In the default state, the vibration plate 42 is horizontal and pushes the top end of the guide member 8 to fit tightly against the trough box 21. At the same time, a certain distance is maintained between the vibration plate 42 and the extension plate 25.

[0039] Since dust and impurities in the condensate will be deposited in the tank box 21, and the dust and impurities will be deposited at the bottom of the tank box 21, in order to continuously discharge the condensate accumulated in the tank box 21, the deposited impurities can be better taken away. Figure 8 As shown in the figure, when the siphon height of the top corner of the siphon channel 24 is reached, the condensate accumulated in the trough box 21 is continuously discharged into the guide member 8 under the action of siphon. At this time, the liquid in the guide member 8 acts on the drain pipe 81, thereby increasing the weight of the drain pipe 81. The increased gravity of the drain pipe 81 presses down on the vibration plate 42, thereby causing the vibration plate 42 to be pressed against the extension plate 25. The elastic plate 4 is vibrated by the blowing vibration of the centrifugal fan 44 on the condensation plate 43 and the vibration of the centrifugal fan 44 itself, so that the vibration plate 42 is pressed against the extension plate 25 when the siphon channel 24 siphons and drains the liquid, thereby driving the trough box 21 to generate a certain vibration. The vibration of the trough box 21 will cause some of the impurities deposited therein to be mixed in the condensate and discharged along with the siphon. Therefore, the vibration of the vibration plate 42 and the drainage of the trough box 21 can reduce the impurities deposited in the trough box 21 and enhance the cleaning effect of the trough box 21. After the liquid in the drain pipe 81 is completely drained, the gravity of the drain pipe 81 decreases and cooperates with the restoration of the vibration plate 42 to move the vibration plate 42 away from the extension plate 25 .

[0040] Another embodiment of the present invention further includes a windshield box 7 located below the trough box 21. The windshield box 7 is structurally divided into an upper inclined portion 71 and a horizontal portion 76. A predetermined distance is maintained between the horizontal portion 76 and the bottom of the trough box 21 to form a second air duct 74. The wind shield box 7 includes a first air duct 75 adjacent to the heat conducting plate 2 , and the first air duct 75 is located at a high position of the upper inclined portion 71 .

[0041] Specifically, the windshield box 7 is fixed to the function box 11 with screws. A drain pipe 81 slides within a side slot 73 defined in the windshield box 7. The drain pipe 81 also slides within an outer slot 13 defined in the outer wall of the function box 11, allowing the drain pipe 81 to move vertically. A shield 15 is fixed within the function box 11 with screws, and a curved roof 14 is provided at the top of the function box 11. The shield 15 is located on one side of the circuit board 22. The horizontal portion 76 maintains a predetermined spacing of 25 mm to 40 mm from the bottom of the trough box 21.

[0042] Further, such as Figure 4 、 Figure 7 and Figure 9 As shown, the first air duct 75 is connected to the second air duct 74, and the first air duct 75 is narrower than the second air duct 74. As the air is blown along the second air duct 74 to the higher first air duct 75, impurities in the dust will be deposited on the lower horizontal portion 76. At the same time, as the air flows along the second air duct 74 to the first air duct 75, the channel gradually narrows. Therefore, due to the Venturi effect, the air speed of the first air duct 75 increases. Since the first air duct 75 is located below the circuit board 22, the fast air flow is used to improve the heat dissipation of the circuit board 22. At the same time, the upward-flowing fast air flow will carry the heat of the circuit board 22 and blow it toward the curved top 14. Since the top of the functional box 11 is relatively cold in a low-temperature environment, when it comes into contact with the hot air flow from the high-temperature circuit board 22, condensation will be generated on the curved top 14. At this time, due to the flow of air and the downward curvature of the curved top 14, the condensation will flow downward along the curved top 14 to prevent dripping onto the circuit board 22 and affecting its use. At the same time, the high wind speed accelerates the evaporation of water vapor on the circuit board 22 .

[0043] As another embodiment provided by the present invention, the function box 11 includes a liquid drain port 12 at the bottom thereof, and air leakage ports 72 on the inner wall of the upper inclined portion 71 are distributed toward the liquid drain port 12 .

[0044] Specifically, such as Figure 10 As shown, the drain port 12 is located at the air outlet of the air leakage port 72, and the drain port 12 is connected to the curved top 14. When the outside of the functional box 11 is at a low temperature, the condensation generated on the curved top 14 flows down to the drain port 12. At this time, part of the air flow on the horizontal portion 76 is discharged along the air leakage port 72 by blowing, and then the air flow of the air leakage port 72 is used to take away part of the dust deposited on the horizontal portion 76. At the same time, the air blowing of the air leakage port 72 blows toward the drain port 12, and then the condensation dripping from the drain port 12 is quickly blown away from the functional box 11 by the air flow of the air leakage port 72, so as to avoid the problem of condensation of the functional box 11 at the drain port 12 due to the slow flow rate.

[0045] As another embodiment further provided by the present invention, a curved plate 41 is provided on the elastic plate 4 , and a curved guide plate 5 plugged into the bottom end of the curved plate 41 moves relative to the windshield box 7 .

[0046] Specifically, a socket is provided at the top of the curved guide plate 5, such as Figure 5 and Figure 3 As shown, the bottom end of the curved plate 41 is inserted into the socket at the top end of the guide plate 5 , thereby completing the connection between the curved guide plate 5 and the curved plate 41 .

[0047] By moving the guide plate 5 so that the guide plate 5 moves relative to the windshield box 7, the guide plate 5 can scrape the dust deposited on the horizontal portion 76, or use the guide plate 5 to block the air leakage port 72 to increase the air volume of the first air duct 75, or extend the air leakage port 72 and close the drain port 12 by moving the guide plate 5, thereby opening it intermittently for concentrated drainage; or vibrate the guide plate 5 to move relative to the windshield box 7 so that the windshield box 7 vibrates to accelerate the falling of dust thereon.

[0048] The curved guide plate 5 can move relative to the windshield box 7 by vibrating the curved plate 41, or by being pushed by an electric push rod. Alternatively, the windshield box 7 can move the curved guide plate 5 relative to the windshield box 7, thereby adjusting the width of the first air duct 75. Alternatively, any other method known to those skilled in the art can be used to move the curved guide plate 5 relative to the windshield box 7.

[0049] As a further optimal embodiment provided by the present invention, a polyamide wheel 62 is provided in the function box 11 and is attached to the curved guide plate 5 .

[0050] Specifically, the system includes a mounting bracket 6 fixedly mounted within the functional box 11 using screws. A curved guide plate 5 is provided with multiple dust accumulation grooves 51, and friction plates 52 are positioned on either side of the grooves. The curved guide plate 5 and friction plates 52 are integrally formed and made of elastic plastic. The mounting bracket 6 is provided with an integral insert plate 61, and a polyamide wheel 62 is rotatably mounted on the insert plate 61 and abuts against the friction plates 52.

[0051] Furthermore, when the curved plate 41 vibrates along with the elastic plate 4, the polyamide wheel 62 moves on the friction plates 52 on both sides of the notch of the dust accumulation groove 51, and the friction between the friction plates 52 and the polyamide wheel 62 generates static electricity. The generated static electricity electrostatically absorbs some impurities in the blast air flowing through the curved guide plate 5, thereby reducing dust in the blast air and preventing dust from accumulating on the circuit board 22 and affecting its use. The polyamide wheel 62 is a brush wheel.

[0052] Working Principle: A centrifugal fan 44 blows air toward the condensation plate 43, causing it to vibrate. The vibration of the condensation plate 43 causes smaller condensation on the plate 43 to collect due to the vibration. The collected condensation forms larger droplets that quickly fall, exposing more of the plate 43's surface for subsequent moisture to better contact the plate 43 and form new condensation, thereby improving condensation formation efficiency. Simultaneously, the vibration of the condensation plate 43 causes the main fins 3 to squeeze the condensation on the condensation plate 43, collecting it. Condensation can also form on the main fins 3, cooling them. Furthermore, if dust is carried in the air passing between the main fins 3 and the condensation plate 43, condensation can absorb some of the dust. When dust adheres to the main fins 3 and the condensation plate 43, the condensation collects and falls, and some of it is transferred to the main fins 3, where it collects and falls. The falling condensation then cleans the dust on the main fins 3 and the condensation plate 43.

[0053] At the same time, when the elastic plate 4 vibrates, the curved plate 41 vibrates along with the elastic plate 4 so that the polyamide wheel 62 rubs against the friction plate 52 to generate static electricity. The generated static electricity allows some impurities in the blast flowing through the curved guide plate 5 to be electrostatically adsorbed, thereby reducing dust in the blast.

[0054] At the same time, the air flowing through the curved guide plate 5 is blown along the second air duct 74 toward the higher first air duct 75. At this point, impurities in the dust are deposited on the lower horizontal portion 76. As the air flows along the second air duct 74 toward the first air duct 75, the passage gradually narrows, thereby utilizing the rapid flow of air to improve heat dissipation from the circuit board 22. Simultaneously, the upward-flowing rapid airflow carries the heat from the circuit board 22 toward the curved top 14. Because the top of the functional box 11 is relatively cool in a low-temperature environment, condensation forms on the curved top 14 when it comes into contact with the hot air flow from the high-temperature circuit board 22. At this time, the airflow and the downward curvature of the curved top 14 cause the condensation to flow downward along the curved top 14, preventing it from dripping onto the circuit board 22 and affecting its use.

[0055] At the same time, part of the airflow on the horizontal portion 76 is discharged along the air leakage port 72, and the airflow of the air leakage port 72 is used to carry away part of the dust deposited on the horizontal portion 76. At the same time, the air blown from the air leakage port 72 is blown toward the drain port 12, so that the condensation dripping from the drain port 12 is quickly blown away from the functional box 11 under the influence of the airflow from the air leakage port 72, so as to avoid the problem of condensation of the functional box 11 at the drain port 12 due to the slow flow rate.

[0056] When the liquid level in the trough box 21 reaches the siphon height, the accumulated condensate in the trough box 21 is continuously drained into the guide member 8 under the action of the siphon. At the same time, the weight of the drain pipe 81 increases, and the gravity of the drain pipe 81 increases, pressing down on the vibration plate 42, which in turn presses the vibration plate 42 against the extension plate 25. At this time, the vibration plate 42 vibrates with the elastic plate 4, causing some impurities deposited in the trough box 21 to be mixed with the condensate and discharged along with the siphon. Therefore, the vibration of the vibration plate 42 and the drainage of the trough box 21 reduce the impurities deposited in the trough box 21 and improve the cleaning effect of the trough box 21. At the same time, the continuous drainage of condensate in a short period of time can prevent the drainage ends of the drain pipe 81 from freezing and clogging.
