Description

Technical Field

[0001] This utility model relates to the field of dehumidification technology, specifically to an automatic dehumidification new energy charging pile. Background Technology

[0002] With the large-scale promotion of new energy vehicles, supporting DC and AC charging piles are widely deployed in various outdoor environments. Due to the high humidity and frequent temperature fluctuations in outdoor environments, especially in high-humidity areas such as the south or coastal regions, moisture in the air easily enters the charging pile, condensing into water droplets and depositing on critical parts such as circuit boards and connectors. This causes electrical faults, insulation degradation, and component corrosion, seriously affecting the safety and lifespan of the charging pile equipment. Therefore, efficient and reliable dehumidification of the charging pile's interior has become one of the key issues urgently needing to be addressed in the technical field.

[0003] Currently, the common dehumidification methods for charging piles in the industry mainly include the following: Adsorption-based dehumidification structures: Some structures use silica gel desiccants, activated carbon packets, etc. to adsorb moisture in the air. They are simple in structure and low in cost, but their moisture absorption capacity is limited. Once saturated, they cannot be regenerated and require regular manual replacement, resulting in a heavy maintenance burden. Furthermore, uneven moisture absorption leads to large fluctuations in efficiency.

[0004] Condensation dehumidification structure: Some products integrate semiconductor cooling chips and condenser plates for dehumidification. Air is cooled and moisture is extracted through the condensation surface. However, this type of structure is prone to condensation and water accumulation. If an effective drainage path is not designed, it may cause internal humidity to increase. At the same time, the energy consumption is relatively high and it cannot operate continuously in a high-humidity environment around the clock.

[0005] Active air circulation system: It introduces outside air through a fan and then processes it through a filter or moisture-absorbing layer. However, this method depends on the ambient temperature and humidity, and the dehumidification capacity fluctuates greatly. In addition, the structure mainly consists of static adsorption materials, which cannot regenerate the moisture-absorbing medium in situ, resulting in limited overall dehumidification efficiency.

[0006] In view of this, we will study and improve upon the existing problems to provide an automatic dehumidification new energy charging pile to solve the current problems. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: an automatic dehumidification new energy charging pile, including: a charging pile body, a water vapor desorption component set on its side, a heat exchanger group set on the top of the water vapor desorption component, and two fans for the cold chamber and the hot chamber respectively. The molecular sieve rotor rotates slowly between the cold and hot areas to realize the dynamic cycle of moisture adsorption and hot air desorption.

[0009] In a preferred embodiment, the water vapor desorption assembly is further configured as follows: the water vapor desorption assembly includes a rotor chamber, a rain cap, and a molecular sieve wheel. The molecular sieve wheel is rotatably disposed inside the rotor chamber. The rain cap is disposed on the top of the rotor chamber and is sealed for protection. The bottom of the rotor chamber is provided with an air outlet and a steam exhaust pipe. The overall structure is compact and highly protective.

[0012] Specifically, the cold compartment absorbs moisture and condenses it into water, while the hot compartment evaporates and discharges the moisture from the molecular sieve using hot air, thus forming an automatic circulating dehumidification system.

[0013] In a preferred embodiment, the molecular sieve wheel is further configured such that it is made of natural or synthetic zeolite molecular sieve material with an average pore size of 0.2–0.4 nm, enabling efficient adsorption of water molecules from the air.

[0014] Specifically, this structure allows adsorption and desorption to occur simultaneously, ensuring continuous operation of the molecular sieve wheel without the need for frequent replacement or shutdown for regeneration.

[0015] In a preferred embodiment, the two fans are further configured such that: the two fans are respectively installed above the cold chamber and the hot chamber; the cold chamber fan draws the humid air inside the charging pile body into the cold chamber for dehumidification; and the hot chamber fan exhausts the heated humid air inside the hot chamber to the outside, thus clearly defining the ventilation path.

[0016] Specifically, the dual-fan configuration enables orderly airflow guidance, ensuring that the cold and hot zones do not interfere with each other, thereby improving the overall system efficiency.

[0017] In a preferred embodiment, the molecular sieve wheel is further configured such that a sealing slip ring is provided on the outer periphery of the molecular sieve wheel and slides in contact with the inner wall of the wheel chamber to ensure the airtightness of the molecular sieve wheel during rotation and prevent moisture leakage or short circuit.

[0018] Specifically, effectively isolating the air in dry and wet zones and maintaining a temperature difference environment between the cold cabin and the hot cabin is the key to efficient dehumidification.

[0019] In a preferred embodiment, the semiconductor cooling chip is further configured such that the cold end is attached to the heat exchange fins inside the cold chamber, and the hot end is attached to the heat exchange fins inside the hot chamber, resulting in a reasonable heat exchange structure arrangement and high thermal conductivity.

[0020] Specifically, the cooling chip operates stably under external power supply and can continuously provide cooling and heating zones without relying on a compressor.

[0021] In a preferred embodiment, the charging pile body is further configured such that the inner wall is provided with a hydrophobic coating to prevent condensate droplets from adhering to the surface of electronic components, thereby further improving the device's moisture-proof and rust-proof performance.

[0022] Specifically, the hydrophobic treatment reduces water droplet residue, improving the operational stability and electrical safety of components.

[0023] In a preferred embodiment, the molecular sieve wheel (230) is further configured such that a sealing slip ring is fitted around its outer periphery, and the sealing slip ring slides against the inner wall of the rotor chamber (210) to improve airtightness and reduce water vapor leakage.

[0024] The beneficial effects achieved by this utility model are as follows: 1.

It has technical advantages such as high efficiency, low energy consumption, and high degree of automation, and is suitable for the long-term stable operation of new energy charging equipment in outdoor high humidity environments. At the same time, it cools and dissipates heat inside the charging pile to maintain the stable operation of the charging pile. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an automatic dehumidification new energy charging pile.

[0031] Combination Figures 1-4 As shown, the present invention provides an automatic dehumidification new energy charging pile, comprising: a charging pile body 100, a water vapor desorption component 200, a heat exchanger group 300, and a fan 400.

[0032] The water vapor desorption assembly 200 is fixedly installed on the side of the charging pile body 100. The water vapor desorption assembly 200 includes a rotating chamber 210, a rain cap 220, and a molecular sieve wheel 230. The molecular sieve wheel 230 is rotatably installed inside the rotating chamber 210. Both ends of the rotating chamber 210 penetrate the outer wall of the charging pile body 100, so that a part of the molecular sieve wheel 230 is located outside the charging pile body 100, and the other part is located inside the charging pile body 100, alternating between the inside and outside during rotation. Specifically, the rotating chamber 210, the molecular sieve wheel 230, and the semiconductor cooling chip 330 are located in the same vertical plane as the side plate of the charging pile body 100.

[0033] The rain cap 220 is fixedly connected to the outer surface of the charging pile body 100 and sealed to the top surface of the turbine chamber 210 to prevent rainwater or external impurities from entering the turbine chamber 210. The bottom surface of the turbine chamber 210 is provided with a steam exhaust port 211 and an air outlet 212. The steam exhaust port 211 is located on the outside of the charging pile body 100, and the air outlet 212 is located on the inside of the charging pile body 100, which are used to exhaust desorbed humid vapor and introduce dry air, respectively.

[0034] A motor 213 is also fixedly installed at the bottom of the rotor chamber 210. The motor 213 is used to drive the molecular sieve wheel 230 to rotate continuously and slowly, so as to realize the dynamic switching of the moisture absorption and desiccation zones. A sealing slip ring is sleeved on the outer periphery of the molecular sieve wheel 230. The sealing slip ring slides against the inner wall of the rotor chamber 210 to improve air tightness and reduce water vapor leakage.

[0035] The heat exchanger assembly 300 is fixedly installed on the top surface of the turbine chamber 210. Its structure includes a semiconductor cooling chip 330 disposed in the center, and cold chambers 310 and hot chambers 320 respectively disposed on the left and right sides of the semiconductor cooling chip 330. The inner sides of the cold chamber 310 and the hot chamber 320 are provided with heat exchange fins 340, and the heat exchange fins 340 are fixedly adhered to the cold end or hot end of the semiconductor cooling chip 330 to achieve effective conduction of cold and heat energy.

[0036] Two fans 400 are fixed on the top surfaces of the cold chamber 310 and the hot chamber 320 respectively. Their bottoms are provided with through holes that correspond to the exhaust pipe 211 and the air outlet 212. The through holes are perpendicular to the surface of the molecular sieve wheel 230, forming a vertically connected air duct structure.

[0037] In a preferred embodiment, the cold chamber 310, the hot chamber 320, the molecular sieve wheel 230, and the rotor chamber 210 are all located in the same vertical plane. Half of the molecular sieve wheel 230 is exposed outside the charging pile body 100, and the other half is embedded inside the charging pile body 100, thereby realizing its dual-zone alternating moisture absorption and dehumidification function driven by the motor 213.

[0038] In a preferred embodiment, the molecular sieve wheel 230 is further configured to be made of natural or synthetic zeolite molecular sieve material with an average surface pore size of 2-4 Å, which has a strong adsorption capacity for moisture.

[0039] In a preferred embodiment, the semiconductor cooling chip 330 is further configured such that: the cooling surface of the semiconductor cooling chip 330 faces the cold compartment 310 inside the charging pile body 100 and is attached to the heat exchange fins 340 on that side; its heating surface faces the outer hot compartment 320 and is fixedly attached to the heat exchange fins 340 inside the hot compartment 320, for heating the air in the hot zone.

[0040] In a preferred embodiment, the molecular sieve wheel 230 is further configured such that a sealing slip ring is fitted around its outer periphery, and the slip ring slides against the inner wall of the wheel chamber 210 to ensure good airtightness during rotation and prevent external humid air from leaking into the dry area.

[0041] In a preferred embodiment, the inner wall surface of the charging pile body 100 is provided with a hydrophobic coating to prevent residual moisture from condensing into droplets, thereby further optimizing the internal moisture-proof performance.

[0042] Specifically, with the above-mentioned structure, the automatic dehumidification new energy charging pile, under the action of the fan 400, draws the humid air inside the charging pile body 100 into the cold chamber 310, where it is condensed and dehumidified by the cooling surface of the semiconductor cooling chip 330 and its matching heat exchange fins 340. The condensed water droplets fall into the bottom of the rotating chamber 210 and are adsorbed by the molecular sieve wheel 230, while the dry air returns to the charging pile body 100 through the air outlet 212. At the same time, the molecular sieve wheel 230 on one side of the hot chamber 320 is heated by the heat exchange fins 340 of the heating surface, completing the efficient desorption of water vapor. The water vapor is discharged through the exhaust pipe 211, thus forming a complete closed-loop dehumidification cycle.

[0043] Working principle and usage process of this utility model: This invention employs a combined dehumidification structure of "molecular sieve rotor + semiconductor heat exchanger + dual-fan ventilation," achieving efficient and automatic water vapor desorption and regeneration through hot and cold zoning and airflow circulation. Its basic principle is as follows: Internal air dehumidification stage moisture absorption Moist air inside the charging pile body 100 is driven by the fan 400 and introduced into the cold chamber 310. The air condenses into droplets upon cooling, drips into the rotor chamber 210, and accumulates on the surface of the molecular sieve wheel 230 for absorption. The cold air further cools the molecular sieve wheel 230, improving its moisture absorption efficiency. The molecular sieve wheel 230 is made of natural or synthetic zeolite material with a pore size of 0.2–0.4 nm, enabling it to efficiently adsorb moisture from the air. The dehumidified air is then discharged into the charging pile body 100 through the outlet. During this process, the airflow inside the charging pile body 100 repeatedly circulates through the cold chamber 310 and the molecular sieve wheel 230 for desorption, further improving the dryness of the internal environment.

[0044] Molecular sieve wheel rotation regeneration stage dehumidification: The molecular sieve wheel 230 is driven by motor 213 to rotate continuously at low speed. While absorbing moisture on one side, the other side comes into contact with hot air in the heat chamber 320. The heat chamber 320 is equipped with heat exchange fins 340 on the heating side. The air is heated by the heating surface of the semiconductor cooling chip 330, which desorbs water vapor from the molecular sieve that has rotated to the hot zone. The moisture evaporates from the molecular sieve and is discharged into the external air through the exhaust pipe 211, thereby realizing the recycling of the molecular sieve wheel 230.

[0045] The temperature control principle of the semiconductor cooling chip: The semiconductor cooling chip 330 continuously works on the heating surface to generate a large amount of heat to heat the heat exchange fins 340 inside the hot chamber 320, thereby raising the temperature of the airflow inside the cold chamber 310 and cooling the part of the molecular sieve wheel 230 that has rotated to the bottom of the cold chamber 310, thus improving the moisture adsorption effect of this part of the molecular sieve wheel 230.
