Description

Technical Field

[0001] The present invention relates to the technical field of wireless charging piles, and in particular to a wireless charging pile device with a cooling function. Background Art

[0002] In recent years, with growing environmental awareness and the intensification of the energy crisis, new energy vehicles (NEVs), as a green and environmentally friendly means of transportation, have experienced rapid development and widespread adoption. New energy vehicles primarily rely on electricity for propulsion, making the construction and improvement of charging infrastructure crucial to their widespread adoption.

[0003] Wireless charging technology, as an emerging charging method, has greatly facilitated the charging of new energy vehicles. It eliminates the constraints of traditional charging cables and allows users to automatically charge their vehicles simply by parking them in a designated charging area, improving both convenience and efficiency. However, during wireless charging, wireless charging stations for new energy vehicles face a more severe heat generation issue than wireless charging for conventional electronic devices.

[0004] New energy vehicles have larger battery capacities and generally require higher charging power, which requires the charging coils of wireless charging stations to generate stronger alternating magnetic fields to transmit large amounts of electrical energy. In this process, the charging coils generate significant heat due to their own resistance. According to Joule's law, Q=I 2 Rt (where Q is heat, I is current, R is resistance, and t is time). High current flowing through a resistor converts a significant amount of electrical energy into heat. Furthermore, the power conversion circuit is responsible for converting high-voltage, high-current AC power into DC suitable for charging the vehicle battery. The electronic components involved, such as rectifier diodes, switches, capacitors, and inductors, consume significant amounts of energy and generate significant heat when operating at high power.

[0005] In addition, the control circuit needs to monitor and precisely control the charging process in real time, including monitoring and adjusting multiple parameters such as charging power, charging status, and battery temperature. Long-term high-load operation will also cause it to generate a certain amount of heat.

[0006] Excessively high temperatures can have numerous adverse effects on wireless charging stations for new energy vehicles. First, high temperatures reduce charging efficiency and prolong charging times, making it impossible to meet users' demands for fast charging and hindering the convenience of new energy vehicles. Second, high temperatures accelerate the aging and damage of electronic components, shortening the lifespan of charging stations, increasing operating costs and increasing maintenance difficulties. More seriously, high temperatures can cause safety incidents such as overheating leading to short circuits and fires, posing a threat to the safety of vehicles and personnel.

[0007] Currently, most wireless charging stations for new energy vehicles lack effective cooling. Some use simple cooling fins to aid heat dissipation, but this is very limited under high-power charging conditions. Some stations are equipped with cooling fans, but these fans lack sufficient heat dissipation capacity to effectively address the overheating issue. Therefore, there is an urgent need to develop a wireless charging station for new energy vehicles with efficient cooling capabilities. Summary of the Invention

When the temperature inside the charging pile rises, the evaporative liquid inside the evaporative liquid tank will quickly liquefy and evaporate. After forming steam, it will enter the evaporator tube. The gas enters the sliding tube along the evaporator tube. Due to the subsequent squeezing of the gas, the movable rod with the connecting frame and the baffle move.

When the temperature inside the charging pile rises, the wax block will gradually melt, so that the coolant inside the coolant tank flows like a three-way valve, and a passage is formed between the connecting pipe, the cooling pipe and the coolant tank, so that the coolant circulates, thereby continuously cooling and dissipating heat for the power converter.

[0020] 3. The wireless charging pile device with cooling function, the semiconductor refrigeration chip will absorb heat at one end and release heat at the other end after being energized. Therefore, the heat-absorbing end of the semiconductor refrigeration chip is set in the liquid storage cavity, and the heat-releasing end of the semiconductor refrigeration chip is set outside the control circuit box. When the current generated on the piezoelectric ceramic plate powers the semiconductor refrigeration chip, the heat-absorbing end of the semiconductor refrigeration chip absorbs heat and the heat-releasing end releases heat. Then the heat-absorbing end of the semiconductor refrigeration chip absorbs the heat of the coolant in the liquid storage cavity, so that the temperature in the coolant is maintained at a lower level, thereby accelerating the cooling of the control circuit box.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] Example 1: In order to solve the problem of poor heat dissipation effect of charging piles in the prior art, please refer to Figures 1-12 , the present invention provides a technical solution: A wireless charging pile device with a cooling function includes a charging pile 1 and a base 2 fixedly connected to the bottom of the charging pile 1. Heat dissipation holes 6 are provided on both sides of the charging pile 1. A display screen 3 is installed on the front of the charging pile 1. A ceiling 5 is fixedly installed on the top of the charging pile 1. Drainage holes 501 are provided on both sides of the upper surface of the ceiling 5. The upper surface of the ceiling 5 is convex in the middle and low on both sides, which allows rainwater to flow smoothly to both sides and be discharged from the drainage holes 501. A cooling fan (not shown in the figure) is also installed on the top of the inner wall of the charging pile 1.

[0027] A heat dissipation device is provided at the bottom of the charging pile 1, and the heat dissipation device includes a ventilation mechanism and a cooling mechanism; The ventilation mechanism includes an evaporative liquid tank 1 601, a liquid inlet pipe 602, an evaporating tube 603, a sliding tube 604, a magnetic block 1 605, a magnetic block 2 606, a movable rod 607, a connecting frame 608 and a baffle 609. The evaporative liquid tank 1 601 is fixedly installed on the inner bottom of the charging pile 1, the liquid inlet pipe 602 is fixedly connected to the top front of the evaporative liquid tank 1 601, the evaporating tube 603 is fixedly connected to the two sides of the top of the evaporative liquid tank 1 601, the sliding tube 604 is fixedly connected to the side of the evaporating tube 603, the magnetic block 1 605 and the magnetic block 2 606 are both slidably connected to the inner wall of the sliding tube 604, the movable rod 607 is fixedly connected to the side of the magnetic block 2 606 away from the magnetic block 1 605, the connecting frame 608 is fixedly connected to the top of the movable rod 607, and the baffle 609 is fixedly connected to the side of the connecting frame 608.

[0028] The sides of magnet block 1 605 and magnet block 2 606 that are close to each other repel each other. Both magnet block 1 605 and magnet block 2 606 are sealed and slidably connected to the inner wall of the sliding tube 604. The sliding tubes 604 are evenly spaced on the sides of the evaporating tube 603. The top of the movable rod 607 is also slidably connected to the inner wall of the sliding tube 604. The interior of the evaporating liquid tank 1 601 is filled with evaporating liquid.

[0029] The side of the baffle 609 is fixedly connected to a retaining frame 611, the outer surface of the sliding tube 604 is fixedly connected to a slide 610, the bottom of the retaining frame 611 is slidingly connected to the slide 610, and the end of the movable rod 607 away from the magnetic block 2 606 is fixedly connected to the telescopic rod 612, and the end of the telescopic rod 612 away from the movable rod 607 is fixedly connected to the inner wall of the charging pile 1.

[0030] During the movement, the movable rod 607 drives the telescopic rod 612 to extend and retract, and at the same time drives the retaining frame 611 to slide on the slide 610, thereby ensuring the stable movement of the movable rod 607 and the baffle 609.

[0031] During the use of the charging pile 1, there may be a high ambient temperature. After the internal temperature of the charging pile 1 rises, the evaporative liquid inside the evaporative liquid tank 1 601 will quickly liquefy and evaporate, and after forming steam, it will enter the evaporator tube 603, and the gas will enter the sliding tube 604 along the evaporator tube 603. Due to the subsequent squeezing of the gas, the magnetic block 1 605 inside the sliding tube 604 will be pushed. Because the side close to the magnetic block 1 605 and the magnetic block 2 606 repel each other, the magnetic block 2 606 will also be pushed under the action of the repulsive force, and the magnetic block 2 606 drives the movable rod 607 to slide, and the movable rod 607 moves with the connecting frame 608 and the baffle 609. When the baffle 609 no longer blocks the heat dissipation hole 6, the outside air can enter the interior of the charging pile 1 through the heat dissipation hole 6, thereby realizing air circulation and avoiding heat accumulation causing the internal temperature of the charging pile 1 to be too high.

[0032] The power converter 8 is fixedly installed on the front of the inner wall of the charging pile 1. The cooling mechanism includes a coolant tank 7, a micro pump 701, a connecting pipe 702, a three-way valve 703, a cooling pipe 704, a heat dissipation fin 705, a connecting spring 706, a wax block 707 and a coolant tank 2 708. The coolant tank 1 7 is fixedly installed on the top of the evaporative liquid tank 1 601, the micro pump 701 is fixedly installed on the top of the coolant tank 1 7, the coolant tank 2 708 is fixedly installed on the front of the inner wall of the charging pile 1, the connecting pipe 702 is fixedly connected to the top of the coolant tank 1 7, and the three-way valve 703 is fixedly connected. At the top of the connecting pipe 702, the cooling pipe 704 is fixedly connected to the side of the three-way valve 703. One side of the cooling pipe 704 is in close contact with the power converter 8, which can achieve good heat dissipation. The heat dissipation fins 705 are fixedly connected to the bottom of the cooling pipe 704. The heat dissipation fins 705 increase the area of ​​contact between the cooling pipe 704 and the air, which can improve the heat dissipation efficiency. The connecting spring 706 is fixedly connected to the inner wall of the three-way valve 703, and the wax block 707 is fixedly connected to the end of the connecting spring 706 away from the inner wall of the three-way valve 703. The three-way valve 703 is connected to the interior of the coolant tank 2 708.

[0033] The micro pump 701 is electrically connected to the control circuit box 401 . Two connecting pipes 702 are provided, and the bottom ends of the two connecting pipes 702 are respectively connected to the input end and the output end of the micro pump 701 . The two connecting pipes 702 are connected through a cooling pipe 704 .

[0034] The interior of the coolant tank 7 is filled with coolant. By starting the micro pump 701, the coolant is input into the connecting pipe 702, and then the coolant flows through the cooling pipe 704 to effectively dissipate heat for the power converter 8, thereby reducing the operating temperature of the power converter 8. After the temperature inside the charging pile 1 rises, the wax block 707 will gradually melt, thereby allowing the coolant inside the coolant tank 2 708 to flow into the three-way valve 703, and form a passage between the connecting pipe 702, the cooling pipe 704 and the coolant tank 1 7, so that the coolant circulates, thereby continuously cooling and dissipating heat for the power converter 8.

[0035] Example 2: During the use of the charging pile 1, the control circuit box 401 is also one of the heat-generating parts. In order to further enhance the heat dissipation effect of the control circuit box 401, the present application installs a control panel 4 on the right side of the charging pile 1, and an exhaust port 402 is opened on the back of the charging pile 1. A fan 403 is fixedly installed in the exhaust port 402, and the fan 403 is electrically connected to the internal circuit structure of the control circuit box 401. The control circuit box 401 is fixedly installed on the left side of the interior of the charging pile 1, and an elastic plate 404 is fixedly connected to the inner wall of the charging pile 1. The elastic plate 404 is convex, and the inner wall of the elastic plate 404 is fixedly connected to a compression spring 4041. The end of the compression spring 4041 away from the inner wall of the elastic plate 404 is fixedly connected to a piezoelectric ceramic plate 4042, and the outer surface of the elastic plate 404 is fixedly connected to an electromagnetic plate 4043.

[0036] A cooling box 405 is fixedly installed on the right side of the control circuit box 401, and a liquid storage chamber 406 is opened inside the cooling box 405. A permanent magnet block 407 is slidably connected to the inner wall of the liquid storage chamber 406, and a telescopic spring 408 is fixedly connected to the side of the permanent magnet block 407. A cooling plate 409 is fixedly connected to the right side of the cooling box 405. The electromagnetic plate 4043 is coupled with the piezoelectric ceramic plate 4042 through an inverter. The cooling plate 409 is a semiconductor cooling plate. The piezoelectric ceramic plate 4042 is coupled with the semiconductor cooling plate 409. The interior of the liquid storage chamber 406 is filled with coolant. The magnetism generated when the electromagnetic plate 4043 is energized is attracted to the magnetism of the permanent magnet block 407.

[0037] After the fan 403 is started, when the air in the exhaust port 402 flows, according to the Bernoulli principle, when the flow is constant, the greater the flow velocity, the smaller the pressure, which makes the flow velocity on one side of the elastic plate 404 faster, and thus the pressure on one side of the elastic plate 404 is smaller, and thus the pressure on one side of the elastic plate 404 is smaller than the pressure on the other side of the elastic plate 404, causing the elastic plate 404 to bulge under the action of the pressure, thereby driving the compression spring 4041 to separate from the piezoelectric ceramic plate 4042, and since the fan 403 is started, the surrounding The air flow rate varies, causing the elastic plate 404 to continuously bulge and contract under the action of pressure and its own elasticity, causing the compression spring 4041 to continuously collide with the piezoelectric ceramic plate 4042, causing the piezoelectric ceramic plate 4042 to continuously generate current. The piezoelectric ceramic plate 4042 is coupled to the semiconductor refrigeration plate 409. Since the direction of the magnetic field of the electromagnetic plate 4043 is related to the direction of the current, the piezoelectric ceramic plate 4042 converts the generated current into alternating current through the inverter, causing the electromagnetic plate 4043 to generate current. The direction of the energized current changes periodically, and the electromagnetic plate 4043 periodically attracts and repels the permanent magnet block 407, causing the permanent magnet block 407 to slide back and forth on the inner wall of the liquid storage chamber 406 under the periodic suction and repulsion of the electromagnetic plate 4043, so that the coolant in the liquid storage chamber 406 circulates, accelerating the absorption of heat in the cooling box 405, thereby reducing the energy consumption generated by the heat dissipation in the control circuit box 401. When the semiconductor refrigeration plate 409 is energized, it absorbs heat at one end and releases heat at the other end. Therefore, the heat-absorbing end of the semiconductor refrigeration chip 409 is set in the liquid storage cavity 406, and the heat-releasing end of the semiconductor refrigeration chip 409 is set outside the control circuit box 401. When the current generated on the piezoelectric ceramic plate 4042 supplies power to the semiconductor refrigeration chip 409, the heat-absorbing end of the semiconductor refrigeration chip 409 absorbs heat and the heat-releasing end releases heat. Then, the heat-absorbing end of the semiconductor refrigeration chip 409 absorbs the heat of the coolant in the liquid storage cavity 406, so that the temperature in the coolant is maintained at a low level, thereby accelerating the cooling of the control circuit box 401.
