Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy charging piles, in particular to a dynamic split type alternating current charging pile. BACKGROUND

[0002] Compared with the direct current integrated charging pile, the split type alternating current charging pile is composed of a charging machine body, a charging gun, a display screen and the like, and the charging machine is usually arranged in a separate cabinet. The direct current integrated charging pile integrates the direct current charger, the control system and the connecting part in one overall device, which is compact in structure and convenient for installation and maintenance.

[0003] According to Chinese Patent Publication No. CN108579349A, published on September 28, 2018, a dry air generator for dehumidifying the circuit board in the charging pile is disclosed, which comprises an air filter, a fan and a semiconductor refrigeration module. The fan is connected with the upper end of the cold end pipeline, and the air filter is connected with the fan. The lower end of the cold end pipeline and the lower end of the hot end pipeline are connected to form a U-shaped air duct. The U-shaped air duct has a drainage port at the bottom. The semiconductor refrigeration module is fixed between the cold end pipeline and the hot end pipeline.

[0004] In the prior art including the above patent, in the use of the split type alternating current charging pile, the circuit board inside the alternating current charging pile generates heat during the operation of charging the automobile. When the temperature of the charging pile shell is relatively low compared with the temperature of the circuit board to form a condensation temperature difference, condensation will be formed inside the charging pile shell, especially in low temperature conditions, which will cause a short circuit risk at the adjacent pin of the circuit board signal terminal PIN and the PIN pin. Therefore, by using the semiconductor refrigeration module and the relatively low humidity or high humidity contact in the above patent, condensation is formed in advance and naturally falls out to reduce the influence of the humidity and condensation in the charging pile on the circuit board. However, in actual use, in some lower temperature environments such as minus 10 degrees to 0 degrees, it is difficult to form condensation when using the semiconductor refrigeration module and low temperature contact, and some formed condensation droplets are slowly discharged through the drainage port. Because the flow rate of the liquid is slow and the surface area of the droplet is large, the liquid is exposed to cold air for a long time, which easily causes condensation below the dew point. When the drainage port droplets gradually condense and accumulate, they will be blocked, which will cause problems such as condensation backflow or condensation inside the charging pile, thereby affecting the use of the charging pile. SUMMARY

[0005] The purpose of the present application is to provide a dynamic split type alternating current 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 blocking the drainage port of the charging pile.

[0016] As a preferred, the wind blocking box is further distributed below the groove box, and the wind blocking box is divided into an upper inclined part and a horizontal part according to the structure, and a predetermined distance is maintained between the horizontal part and the bottom of the groove box to form a second air duct.

[0035] 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.

[0036] like Figures 1-10 As shown, a dynamic split-type AC charging pile includes a function box 11 installed on the pile body 1. The function box 11 includes:

[0037] A heat-conducting plate 2 on which a circuit board 22 is fixedly mounted has fins 3 that are evenly distributed and vertically arranged on one side.

[0038] A condensation plate 43 is inserted between the fins 3 and maintains a certain distance from them;

[0039] A trough 21 fixed to the heat-conducting plate 2 to receive condensation has a siphon channel 24 opened inside at a predetermined height from the bottom.

[0040] Specifically, the heat-conducting plate 2 is fixedly installed inside the functional box 11 using screws, and the slot box 21 is welded to the heat-conducting plate 2. The circuit board 22 is fixedly installed to the heat-conducting plate 2 using screws, and the fins 3 are fixedly welded to the heat-conducting plate 2 on one side opposite to the circuit board 22. The heat-conducting plate 2 is made of aluminum alloy plate, and the slot box 21 is made of 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 shell of the functional box 11 to the outside of the functional box 11. By utilizing the power semiconductor devices on the circuit board 22, such as IGBTs and MOSFETs, in the process of controlling AC conversion, rectification, and frequency conversion, a large amount of heat is generated. The rectifier bridge and frequency conversion circuit on the circuit board 22 also generate heat in the process of converting AC to DC or adjusting AC parameters. The distance between the fins 3 and the condensation plates 43 is 1mm-3mm.

[0041] Further, by using the heat conduction plate 2 to absorb the heat generated by these devices and transfer to the fins 3, at this time by the fins 3 to heat the air around it, and the condensation plate 43 contact function box 11 outside the air, when the environment is in low temperature, at this time the fin 3 around the relative condensation plate 43 temperature of the hot and humid air contact condensation plate 43 will form condensation, so by the fin 3 to enhance the heat dissipation of the circuit board 22 while being able to heat the air, so as to enhance the formation of condensation on the condensation plate 43, and then the formed condensation along the condensation plate 43 falls into the groove box 21 to collect, so in low temperature environment using the circuit board 22 itself heat to accelerate the formation of condensation in the function box 11 and collection, thereby reducing the humidity in the function box 11 on the influence of the circuit board 22. At the same time solves the problem of some only using semiconductor refrigeration module in low temperature difficult to form condensation.

[0042] Further, since part of the heat on the heat conduction plate 2 will be transferred to the condensation liquid in the groove box 21, so as to avoid condensation condensation, when the collected condensation liquid in the groove box 21 rises and reaches the siphon height, at this time using the siphon effect to continuously discharge the collected condensation in a short time, so as to avoid the problem of slow and continuous condensation discharge, easy to freeze and block.

[0043] Further, the condensation plate 43 is an aluminum alloy plate.

[0044] In the above technical solution, by using the heat of the circuit board 22 itself to heat the fins 3 on the heat conduction plate 2, and then the fins 3 heat the low temperature and 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, and then the condensation is collected in the groove box 21 and reaches a certain amount, along the siphon tube 24 is siphoned out continuously, so as to solve the problem of slow and continuous condensation discharge, easy to freeze and block.

[0045] As a further embodiment of the present application, the function box 11 is fixedly provided with an outlet fan 44 distributed towards the condensation plate 43.

[0046] Specifically, the centrifugal fan 44 is fixedly installed in the functional box 11 by screws, and the centrifugal fan 44 is located above the condensation plate 43. By enabling the functional box 11 to be opened and closed, when the external air temperature is high, the window located on the side of the air inlet of the centrifugal fan 44 of the functional box 11 is opened, so that the centrifugal fan 44 can suck in external air to ventilate and cool the functional box 11. When the external humidity is high or the air temperature is low, the window is closed, so that the centrifugal fan 44 performs internal circulation dehumidification and certain heat preservation effect in the functional box 11, thereby reducing the humidity and excessively low temperature in the functional box 11 to affect the formation of condensation. The opening and closing of the window can be achieved by manually taking and placing the baffle, or by driving the baffle to flip by a motor, or by opening the window in a manner known to those skilled in the art.

[0047] As another embodiment provided by the present application, the condensation on the condensation plate 43 is shaken to move the condensation between the main fins 3.

[0048] Specifically, the vibration of the condensation plate 43 causes the small condensation on the condensation plate 43 to gather, and the gathered condensation forms larger water droplets that quickly fall. At this time, as shown in Figure 6 the vibration of the condensation plate 43 accelerates the condensation to gather into water droplets and fall, thereby exposing more of the surface of the condensation plate 43 to facilitate the contact of subsequent humidity with the condensation plate 43 to form new condensation, thereby avoiding the situation where small local condensation occupies most of the outer surface of the condensation plate 43, which reduces the efficiency of the contact between humidity and the condensation plate 43. At the same time, the vibration of the condensation plate 43 causes the main fins 3 to press the condensation on the condensation plate 43 to gather, and the main fins 3 can also have condensation attached thereto to cool the main fins 3. If dust is carried in the air between the main fins 3 and the condensation plate 43, part of the dust can be absorbed by the condensation, and when the dust adheres to the main fins 3 and the condensation plate 43, the condensation gathers and falls and is partially transferred to the main fins 3 to gather and fall, thereby using the falling condensation to clean the dust on the main fins 3 and the condensation plate 43.

[0049] The vibration of the condensation plate 43 can be achieved by an ultrasonic generator, or by a vibration motor connected to a connecting rod connected to multiple condensation plates 43, or by a manner known to those skilled in the art for driving the condensation plate 43 to vibrate.

[0050] As another embodiment provided by the present application, a baffle 31 is fixedly installed at the top of every two fins 3 and arranged in a linear array to block part of the air duct of the centrifugal fan 44.

[0051] Specifically, the fins 3 can be fixedly installed on the inner wall of the function box 11 by screws, and a plurality of shielding plates 31 are sequentially welded on the top of the plurality of fins 3. The shielding plates 31 are used to close the direct gaps between the fins 3. At this time, the top of the fins 3 between every two shielding plates 31 forms a wide opening, and the gap between two fins 3 is relatively narrow. Therefore, a Venturi structure is formed. At this time, the air flow rate between the fins 3 is increased by the shielding plates 31. When the centrifugal fan 44 blows, the condensation plate 43 between the fins 3 is vibrated, thereby increasing the falling rate of the condensation and accelerating the condensation collection. The surface of the vibrating condensation plate 43 is not easy to attach dust.

[0052] As another embodiment provided by the present application, an elastic plate 4 fixedly connected with the plurality of condensation plates 43 is further included, which is parallel to the heat conduction plate 2.

[0053] Specifically, the plurality of condensation plates 43 are respectively fixedly welded on the elastic plate 4. The top end of the elastic plate 4 is fixedly installed on the centrifugal fan 44 by screws, and the bottom of the elastic plate 4 is in a movable state. The condensation plate 43 is surrounded by the elastic plate 4. The vibration generated by the centrifugal fan 44 is transmitted to the plurality of condensation plates 43 through the elastic plate 4. At the same time, the blowing of the centrifugal fan 44 along the condensation plate 43 and the fin 3 can be limited. The blowing of the elastic plate 4 also causes the elastic plate 4 to vibrate. Therefore, the outer wall surface of the elastic plate 4 on one side of the heat conduction plate 2 can also be used as a surface for forming condensation. The elastic plate 4 is an elastic stainless steel plate.

[0054] Further, as shown in Figure 5 and Figure 8 the bottom end of the elastic plate 4 is fixedly welded with a curved plate 41. When it is in low-temperature weather, the cold air outside or in the function box 11 is blown between the condensation plate 43 and the fin 3 by the centrifugal fan 44. Then, the condensation and dust removal are performed by the condensation plate 43 and the fin 3. Subsequently, the blowing is separated from the condensation plate 43 and the fin 3 and is blown into the groove box 21. At this time, the liquid surface in the groove box 21 further absorbs the dust in the air. At the same time, the groove box 21 is at a low position to achieve the deposition of the dust in the blowing. Then, the blowing flows along the surface of the curved plate 41 to facilitate the blowing of the dehumidified and de-dusted air to the circuit board 22, thereby improving the service life of the circuit board 22.

[0055] As the optimal embodiment provided by the present application, the vibration plate 42 fixedly installed on the elastic plate 4 is in contact with the guide 8 slidably installed on the liquid outlet of the siphon 24, and the two are in a vertical relationship.

[0056] The vibration plate 42 in the default state is in a horizontal state and is distributed in parallel with the extension plate 25 fixedly installed at the bottom of the groove box 21.

[0057] Specifically, the extension plate 25 is fixedly welded to the bottom of the groove box 21. The bottom end of the guide 8 is fixedly communicated with a drain pipe 81, and the guide 8 and the drain pipe 81 are an integral hard plastic pipe. The outer wall of the groove box 21 on one side of the guide 8 is fixedly installed with a sealing rubber ring 23. The outer wall of the drain pipe 81 is fixedly bonded with a shock-absorbing rubber pad 82 by glue. The vibration plate 42 is fixedly welded to the elastic plate 4 and is located below the drain pipe 81 and is attached to the shock-absorbing rubber pad 82. In the default state, the vibration plate 42 is in a horizontal state and pushes the top end of the guide 8 to tightly attach to the groove box 21. At the same time, the vibration plate 42 and the extension plate 25 maintain a certain distance.

[0058] Since dust impurities in the condensate liquid will be deposited in the bottom of the groove box 21, in order to continuously drain the accumulated condensate in the groove box 21 and better remove the deposited impurities, when the liquid level in the groove box 21 reaches the siphon height of the top corner of the siphon channel 24 as shown in Figure 8 At this time, the accumulated condensate in the groove box 21 continuously drains into the guide 8 under the action of siphon, and the liquid in the guide 8 acts on the drain pipe 81, thereby increasing the weight of the drain pipe 81, and the gravity of the drain pipe 81 presses on the vibration plate 42, thereby making the vibration plate 42 press and attach to the extension plate 25. Since the elastic plate 4 is vibrated by the air blowing vibration of the condensate plate 43 by the centrifugal fan 44 and the vibration of the centrifugal fan 44 itself, the vibration plate 42 is attached to the extension plate 25 when the siphon channel 24 siphons the liquid, thereby driving the groove box 21 to generate a certain vibration, and the vibration of the groove box 21 mixes part of the deposited impurities in the condensate liquid and is drained out with the siphon, thereby reducing the deposited impurities in the groove box 21 and improving the cleaning strength of the groove box 21 through the vibration of the vibration plate 42 and the liquid drainage in the groove box 21. After the liquid in the drain pipe 81 is drained out, the gravity of the drain pipe 81 decreases to reset the vibration plate 42 to move away from the extension plate 25.

[0059] As another embodiment of the present application, a wind-blocking box 7 is also arranged below the groove box 21, which is divided into an upper inclined part 71 and a horizontal part 76 according to the structure, and a predetermined distance is maintained between the horizontal part 76 and the bottom of the groove box 21 to form a second air channel 74.

[0060] The wind-blocking box 7 includes a first air channel 75 distributed adjacent to the heat-conducting plate 2, and the first air channel 75 is distributed at a high position of the upper inclined part 71.

[0061] Specifically, the wind shield box 7 is fixedly installed on the function box 11 by screws. The drain pipe 81 is slidably arranged in the side slot 73 formed on the wind shield box 7, and the drain pipe 81 also slides in the outer slot 13 formed on the outer wall of the function box 11. The side slot 73 and the outer slot 13 are used to enable the drain pipe 81 to move in the vertical direction. The shutter 15 is fixedly installed in the function box 11 by screws, and the curved top 14 is arranged at the top of the function box 11. The shutter 15 is located on one side of the circuit board 22. The distance between the horizontal part 76 and the bottom of the slot box 21 is 25-40 mm.

[0062] Further, as shown in Figure 4 、 Figure 7 and Figure 9 , 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. When the air flow along the second air duct 74 flows to the first air duct 75 at the high position, the impurities in the dust will deposit on the horizontal part 76 at the low position. As the air flow along the second air duct 74 gradually narrows to the first air duct 75, the air speed of the first air duct 75 increases according to the Venturi effect. Since the first air duct 75 is located below the circuit board 22, the fast flowing air is used to improve the heat dissipation of the circuit board 22. The upward flowing fast air will drive and blow the heat of the circuit board 22 to the curved top 14. Since the top of the function box 11 is cold in a low-temperature environment, when the hot air flow on the circuit board 22 contacts the cold top, condensation will be generated on the curved top 14. The condensation will flow downward along the curved top 14 to avoid dropping on the circuit board 22 and affecting the use of the circuit board 22. At the same time, the high air speed accelerates the evaporation of water vapor on the circuit board 22.

[0063] As another embodiment of the present application, the drain port 12 is formed at the bottom of the function box 11, and the air leakage port 72 formed in the inner wall of the upper inclined part 71 is distributed towards the drain port 12.

[0064] Specifically, as shown in Figure 10 , the drain port 12 is located at the air port of the air leakage port 72, and the drain port 12 is connected to the curved top 14. When the outside of the function box 11 is in a low-temperature environment, the condensation generated on the curved top 14 flows to the drain port 12. At this time, part of the air flow on the horizontal part 76 is used to flow along the air leakage port 72, and the air flow of the air leakage port 72 is used to carry away part of the dust deposited on the horizontal part 76. At the same time, the air flow of the air leakage port 72 blows to the drain port 12, so that the condensation dropped from the drain port 12 is quickly blown away from the function box 11 under the driving of the air flow of the air leakage port 72, to avoid the problem of slow condensation of the condensation of the drain port 12 in the function box 11.

[0065] As further provided by the present application, the curved plate 41 is arranged on the elastic plate 4, and the bottom end of the curved plate 41 is inserted into the curved guide plate 5.

[0066] Specifically, the top end of the curved guide plate 5 is provided with a socket, as shown in Figure 5 and Figure 3 the bottom end of the curved plate 41 is inserted into the socket of the top end of the guide plate 5, so that the curved guide plate 5 and the curved plate 41 are connected.

[0067] By moving the guide plate 5, the guide plate 5 can be moved relative to the wind-blocking box 7, so that the guide plate 5 can shovel the dust deposited on the horizontal part 76, or the guide plate 5 can block the air leakage hole 72 to increase the air volume of the first air duct 75, or the guide plate 5 can be moved to extend the air leakage hole 72 and close the drain hole 12, so that the drain hole 12 is intermittently opened to concentrate the drainage; or the guide plate 5 can be vibrated to move relative to the wind-blocking box 7 to vibrate the wind-blocking box 7 to accelerate the dust falling off the wind-blocking box 7.

[0068] The moving mode of the curved guide plate 5 relative to the wind-blocking box 7 can be that the curved guide plate 5 is vibrated with the curved plate 41 to move relative to the wind-blocking box 7, or the curved guide plate 5 is pushed by the electric push rod to move relative to the wind-blocking box 7, or the wind-blocking box 7 is moved to move the curved guide plate 5 relative to the wind-blocking box 7, so that the movement of the wind-blocking box 7 adjusts the width of the first air duct 75, or any other mode known to those skilled in the art.

[0069] As the most preferred embodiment of the present application, the functional box 11 is provided with a polyamide wheel 62 attached to the curved guide plate 5.

[0070] Specifically, the mounting bracket 6 is fixedly installed in the functional box 11 by screws, the curved guide plate 5 is provided with a plurality of dust accumulation grooves 51, and the curved guide plate 5 is provided with friction plates 52 on both sides of the groove openings of the dust accumulation grooves 51, the curved guide plate 5 and the friction plates 52 are of an integrated structure, and the curved guide plate 5 and the friction plates 52 are made of elastic plastic. The mounting bracket 6 is provided with an integrated plug-in plate 61, and the polyamide wheel 62 is rotatably arranged on the plug-in plate 61 and attached to the friction plates 52.

[0071] Further, when the curved plate 41 is vibrated with the vibration of the elastic plate 4, the polyamide wheel 62 moves on the friction plates 52 on both sides of the groove openings of the dust accumulation grooves 51, and the friction between the friction plates 52 and the polyamide wheel 62 generates static electricity, so that part of the impurities in the air flowing through the curved guide plate 5 are attracted by the static electricity, thereby reducing the dust in the air and reducing the accumulation of dust on the circuit board 22 to affect the use of the circuit board 22. The polyamide wheel 62 is a brush wheel.

[0072] Working principle: The centrifugal fan 44 blows air to the condensation plate 43, and then the air drives the condensation plate 43 to vibrate, and then the condensation plate 43 vibrates to make the smaller condensation on the condensation plate 43 gather due to vibration, and the gathered condensation forms larger water droplets that quickly fall, thereby exposing more of the surface of the condensation plate 43 to facilitate subsequent contact with the condensation plate 43 by the humid air to form new condensation, improving the efficiency of condensation formation. At the same time, due to the vibration of the condensation plate 43, the condensation on the condensation plate 43 is squeezed by the main fin 3 to gather, and the main fin 3 can also be attached with condensation to cool the main fin 3, and if dust is carried in the air between the main fin 3 and the condensation plate 43, part of the dust can be absorbed by the condensation, and when the dust adheres to the main fin 3 and the condensation plate 43, at this time the condensation is gathered and falls, and part of it is transferred to the main fin 3 to gather and fall, thereby using the falling condensation to clean the dust on the main fin 3 and the condensation plate 43.

[0073] At the same time, when the elastic plate 4 vibrates, the curved plate 41 vibrates with the elastic plate 4 to generate static electricity by the polyamide wheel 62 rubbing on the friction plate 52, and part of the impurities in the air flowing through the curved guide plate 5 are attracted by the static electricity, thereby reducing the dust in the air.

[0074] At the same time, the air flowing through the curved guide plate 5 blows along the second air duct 74 to the high-position first air duct 75, at this time the impurities in the dust will deposit on the horizontal part 76 located at the low position, and at the same time the channel gradually narrows as the air flows along the second air duct 74 to the first air duct 75, thereby using the fast-flowing air current to improve the heat dissipation of the circuit board 22. At the same time, the upward flowing fast air current will drive the heat of the circuit board 22 and blow it towards the curved top 14, since the top of the functional box 11 is relatively cold in a low-temperature environment, when it contacts the hot air current on the circuit board 22, it will generate condensation on the curved top 14, at this time the condensation flows down along the curved top 14 due to the flow of the air current and the downward curvature of the curved top 14, thereby avoiding the condensation from dripping onto the circuit board 22 and affecting the use of the circuit board 22.

[0075] At the same time, part of the air current on the horizontal part 76 flows out along the air leakage opening 72, thereby using the air current of the air leakage opening 72 to carry away part of the dust deposited on the horizontal part 76, and at the same time the air blowing from the air leakage opening 72 blows towards the drain opening 12, thereby making the condensation dripping from the drain opening 12 quickly blown away from the functional box 11 under the action of the air current of the air leakage opening 72, to avoid the problem of slow condensation of the condensation on the drain opening 12 of the functional box 11.

[0076] When the liquid level in the groove box 21 reaches the siphon height, the condensed water accumulated in the groove box 21 continuously drains into the guide 8 under the siphon effect, and the weight of the drain pipe 81 increases, and the gravity of the drain pipe 81 enhances the pressure on the vibration plate 42, so that the vibration plate 42 is pressed and fitted on the extension plate 25, at this time, the vibration plate 42 vibrates with the elastic plate 4 to mix the impurities deposited in the groove box 21 with the condensed water and drain out with the siphon, so that the vibration of the vibration plate 42 and the drainage in the groove box 21 can reduce the impurities deposited in the groove box 21 and improve the cleaning effect of the groove box 21. At the same time, the continuous drainage of the condensed water in a short time can avoid the problem that the drainage ends of the two ends of the drain pipe 81 are frozen and blocked.

[0077] The foregoing merely illustrates some exemplary embodiments of the present application, and it is obvious to those skilled in the art that various modifications can be made to the described embodiments without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature, and should not be construed as limiting the scope of the claims of the present application.
