Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a liquid-cooled super charging pile for fast charging of low-altitude aircraft. Background Art

[0002] With the continuous expansion of the low-altitude aircraft market, the demand for charging piles will continue to grow. Charging piles are connected to the mains or other power sources to provide the electrical energy required for the charging process. Inside the charging piles, power electronic devices such as rectifiers and filters play a key role. For AC charging piles, these devices convert the input AC power into DC power. Because the battery system of low-altitude aircraft usually needs to be charged with DC power, the low-altitude aircraft is connected to the charging pile through the charging interface to establish a channel for power transmission; Defects: However, the heat dissipation effect of the charging piles on the market is poor, which greatly reduces the user experience; In order to solve the above-mentioned defect one, the prior art one (application number: 202021958406.8, Chinese patent with the authorization announcement date of 2021-04-13) discloses a charging pile with energy control function, which can control the output power according to the number of charged vehicles. At the same time, the various devices are arranged at intervals, so that the heat dissipation effect is good, which greatly improves the user experience; Defect two: Under the tension of the tension spring, the tension spring pulls the pull rope from the pull rope winding roller The cable winding roller is unrolled, and the pulling rope drives the rope winding roller, the rotating shaft and the cable winding roller to rotate in opposite directions. The cable winding roller winds the charging cable on the cable winding roller to realize automatic winding of the charging cable. However, after long-term use, the tension of the winding spring in the device will be reduced. After a period of use, the charging cable cannot be retracted normally. In order to solve the second defect, the prior art 2 (application number: 202320795717.4, the authorization announcement date is 2023-08-29 Chinese patent) discloses an automatic winding charging For the charging pile, when charging is completed, unplug the charging head from the car, and the charging head no longer applies pulling force to the power cord. The weight inside the charging pile body moves downward, and the downward movement of the weight drives the roller to rotate. The rotation of the roller can reel in the power cord, and the downward movement of the weight drives the roller to rotate to reel in the power cord; turn the first handle, and the first handle can drive the threaded rod to move downward. The downward movement of the threaded rod can drive the moving wheel line to move downward, so that the moving wheel contacts the ground, and the moving wheel is driven to rotate by pushing the charging pile body.

[0003] The prior art is to reel in the power cord by utilizing the downward movement of a heavy object to drive the drum to rotate, but each time the user pulls out a section of the power cord, it is unable to fix it, so that once the user lets go, the power cord will be retracted, resulting in inconvenience in use. At the same time, since most charging piles are placed outdoors for use, a large amount of dust and impurities will adhere to the surface of the heat dissipation net, which will then block the heat dissipation net, resulting in the inability to discharge the heat inside the charging pile and affecting the heat dissipation of the charging pile. Therefore, we propose a liquid-cooled super charging pile for fast charging of low-altitude aircraft to solve the above-mentioned problems. Summary of the invention

Rain covers 3 are fixedly connected to the upper position of the charging gun 2 on both sides of the shell 1, and the rain covers 3 are set in a semicircular shape.

[0041] During use, the user can select the charging mode, start charging, set parameters, etc. through the display screen and operation buttons on the front of the shell 1. Then the user unplugs the left or right charging gun 2 from the socket on the shell 1, and inserts the charging gun 2 into the charging port on the low-altitude aircraft for charging. The charging module inside the shell 1 is used to convert the input AC power into DC power suitable for charging the low-altitude aircraft.

[0042] Embodiment 2: Different from Embodiment 1, this embodiment uses the coolant inside the cooling tube 5 to cool the battery module inside the housing 1 to ensure the performance of the charging pile. For details, refer to Figure 1 and Figure 4 As shown, a liquid storage tank 4 is fixed on the top of the shell 1, a cooling pipe 5 is installed at the rear end of the shell 1, and a circulating pump 6 is bolted to the right side of the bottom of the inner wall of the shell 1, and a circulating pipe 8 is arranged on the right side of the shell 1, and both ends of the cooling pipe 5 are fixedly connected to the bottom of the liquid storage tank 4 and the left end of the circulating pump 6 respectively, and both ends of the circulating pipe 8 are fixedly connected to the right side of the liquid storage tank 4 and the right end of the circulating pump 6 respectively, and the liquid storage tank 4, the cooling pipe 5, the circulating pump 6 and the circulating pipe 8 are internally connected to each other, and a one-way valve is installed inside the upper ends of the cooling pipe 5 and the circulating pipe 8.

[0043] The coolant inside the liquid storage tank 4 enters the cooling pipe 5, which can absorb the heat generated by the battery during the charging process, ensuring that the temperature of the battery and the charging system is always controlled within a safe and efficient range. At the same time, it absorbs the heat and cools down, and then starts the circulation pump 6 to return the used coolant inside the cooling pipe 5 to the liquid storage tank 4. After the coolant temperature drops, it returns to the cooling pipe 5 for cooling again, thereby realizing circulating liquid cooling and improving cooling efficiency.

[0044] Embodiment 3: Different from Embodiment 2, this embodiment utilizes the potential energy of the coolant flow to drive the fan to rotate, and cooperates with the heat sink 18 to quickly cool the used coolant to ensure the next cooling use. For details, refer to Figure 1 , Figure 6 and Fig. 9 As shown, an exhaust passage 17 is fixed on the upper right side of the shell 1, and a transmission rod 16 is arranged inside the exhaust passage 17, the right end of the transmission rod 16 is fixedly connected to a fan, a dust screen 19 is installed on the right bolt inside the exhaust passage 17, the inside of the circulation pipe 8 is connected to the impeller 15 through an axis rotation, the shaft end of the impeller 15 and the left end of the transmission rod 16 are connected through a bevel gear set, and a protective shell 21 is installed on the outside of the bevel gear set, a protective cover 26 is fixedly connected to the top of the liquid storage tank 4, and air inlet holes are opened on the left side of the protective cover 26 at equal intervals, an exhaust pipe 20 is fixedly connected between the exhaust passage 17 and the protective cover 26, heat sinks 18 are fixedly penetrated and fixed at equal intervals on the top of the inner wall of the liquid storage tank 4, and the tops of multiple heat sinks 18 extend into the interior of the protective cover 26, the left end of the transmission rod 16 extends into the interior of the circulation pipe 8, the transmission rod 16 is connected to the exhaust passage 17 and the circulation pipe 8 by bearings, and the exhaust passage 17 and the protective cover 26 are connected through the exhaust pipe 20.

[0045] When the coolant is pumped into the liquid storage tank 4 under the action of the circulation pump 6, the heat in the coolant will be transferred to the multiple heat sinks 18, and then the outside air enters the inside of the protective cover 26 from the multiple air inlet holes on the left side and flows through the multiple heat sinks 18. The heat of the heat sink 18 will be transferred to the air. By accelerating the air circulation inside the protective cover 26, the heat of the heat sink 18 can be continuously taken away, so that the coolant can be indirectly dissipated, ensuring the heat dissipation effect of the coolant;

[0046] The potential energy of the coolant flowing in the circulation pipe 8 is used to drive the impeller 15 to rotate, so that the impeller 15 drives the transmission rod 16 to rotate using the bevel gear set. At the same time, the transmission rod 16 drives the fan to rotate and cooperates with the exhaust pipe 20 to discharge the heat absorbed by the coolant inside the protective cover 26 through the exhaust channel 17, thereby ensuring the air circulation inside the protective cover 26. The structure is reasonable.
