Description

Technical Field

[0001] This utility model belongs to the technical field of high-power charging piles and relates to an air-cooled high-power charging pile. Background Technology

[0002] A charging pile is a dedicated charging device that provides electrical replenishment for new energy vehicles, similar in function to a gas pump at a traditional gas station. Among the various performance parameters of a charging pile, charging power directly affects charging speed and user experience. The higher the charging power, the shorter the charging time. For example, a 300kW charging pile (supercharging pile) can charge a battery to 80% in 15-30 minutes, while a 60kW charging pile (fast charging pile) may take 1-2 hours.

[0003] High-power charging stations can effectively reduce users' charging waiting time, but the heat dissipation performance of the charging station is a key factor limiting charging power. During discharge, the internal power modules, capacitors, transformers, and other components of the charging station generate a large amount of heat. To prevent overheating and potential fires or short circuits, a protection function is triggered when the internal temperature of the charging station exceeds a safety threshold, actively reducing the charging power. When the charging station triggers the protection function due to overheating, the actual charging power is generally 50%-70% of the design value.

[0004] Existing charging piles typically use either air cooling or liquid cooling for heat dissipation. Liquid cooling has higher heat dissipation efficiency, but cavitation occurs when the coolant temperature is ≥45℃, and the heat exchange efficiency will decrease significantly at this temperature. This requires additional cooling towers. In addition, liquid cooling systems are extremely expensive, making it difficult to popularize them on a large scale. Furthermore, it is necessary to strictly prevent coolant leakage, which places extremely high demands on sealing.

[0005] Compared to liquid cooling, air cooling offers advantages such as lower cost, ease of large-scale deployment, and no risk of cavitation or leakage. However, air cooling has relatively low heat dissipation efficiency, relying primarily on fans or blowers to draw in outside air filtered through a filter before introducing it into the charging station for heat exchange with the radiator surface. Therefore, air cooling effectiveness is significantly affected by outside air temperature; cooling capacity decreases noticeably at higher ambient temperatures. Airflow volume is also a key factor; insufficient airflow drastically reduces cooling performance. Under conditions of high airflow or poor outside air quality, the filter is easily clogged with dust, leading to a significant reduction in airflow. Therefore, current air-cooled charging stations cannot meet the demands of high-power charging and have room for improvement. Utility Model Content

[0011] Preferably, the first cabinet door has an open position and a closed position; when the first cabinet door is in the open position, the first hollow area is offset from the inlet of the air duct, and the second hollow area is offset from the filter module; when the first cabinet door is in the closed position, the first hollow area is connected to the inlet of the air duct, and the second hollow area is connected to the filter module.

[0012] Preferably, the ventilation module includes a plurality of exhaust fans arranged in an array, each of which is installed on the second cabinet door.

[0013] Preferably, the air duct has a flared structure with one large port and the other small port, the large port of the air duct is connected to the cold air inlet, and the small port of the air duct is connected to the air outlet of the air conditioning module.

[0014] Preferably, the filter module further includes a filter channel and a fine filter element. The two ends of the filter channel are respectively connected to the air inlet of the cyclone dust collector and the air conditioning module, and the fine filter element is installed in the filter channel.

[0015] Preferably, the cyclone dust collector includes a dust collector housing, a negative pressure suction pipe, and at least one centrifugal separation unit; The dust collector housing is provided with an independent air inlet chamber, a negative pressure chamber and a dust collection chamber, and the negative pressure suction pipe is connected to the negative pressure chamber. The centrifugal separation unit includes an air inlet pipe and an exhaust pipe. The inlet of the air inlet pipe is connected to the air inlet chamber, and the outlet of the air inlet pipe is connected to the dust collection chamber. The end of the air inlet pipe near the dust collection chamber is configured as a conical cavity structure with a diameter that gradually decreases in the direction of the dust collection chamber. A portion of the exhaust pipe is inserted into the inlet of the air inlet pipe, and the inlet of the exhaust pipe is connected to the interior of the air inlet pipe. The outlet of the exhaust pipe is connected to the negative pressure chamber. A spiral guide vane is provided between a portion of the outer wall surface of the exhaust pipe and the inner wall surface of the air inlet pipe.

[0016] Preferably, a module compartment is installed inside the outer casing, the charging module is installed inside the module compartment, and the module compartment has openings at both ends. The cold air inlet and the hot air outlet are respectively located at the two openings at the two ends of the module compartment.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This charging station can achieve high-power charging while maintaining air cooling. The cyclone dust collector can efficiently remove dust while maintaining a large airflow. The airflow will not decrease throughout the entire service life, so the air cooling efficiency will not drop. The filtered air passes through the air conditioning module to form cold air, which is directly introduced into the charging module for heat exchange, eliminating the restriction of the external environment on the air cooling efficiency.

[0018] 2.

[0019] 3. The industrial air conditioner is embedded in the installation cavity of the first cabinet door. After the industrial air conditioner is installed, the air inlet, air outlet and exhaust outlet of the industrial air conditioner are aligned with the corresponding hollow area. It does not need to be directly connected to the air duct and filter module, but is connected through the hollow area with fixed position, which greatly reduces the assembly difficulty.

[0020] 4. The core function of the exhaust fan is to force airflow circulation. The exhaust fan generates negative pressure through the high-speed rotation of the blades, which quickly exhausts the hot air blown out of the hot air outlet into the casing.

[0021] 5. The flared structure of the air duct accelerates airflow speed through a tapering design (from the large port to the small port), utilizing the Venturi effect (fluid velocity increases and pressure decreases in a narrow cross-section) to enhance the kinetic energy of the airflow within the duct. After entering from the large port, the cold air is accelerated through the narrow small port, forming a high-pressure, high-speed airflow that directly acts on the cold air inlet of the charging module, thereby further improving the cooling effect by increasing the airflow speed.

Detailed Implementation

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figures 1 to 10 As shown, a wind-cooled high-power charging pile includes: The outer casing 100 contains a charging module 200 and an air duct 300. The charging module 200 has a cold air inlet 210, and the outlet of the air duct 300 is connected to the cold air inlet 210. Air conditioning module 400, the air outlet of air conditioning module 400 is connected to the inlet of air duct 300, and the exhaust outlet of air conditioning module 400 is set to face the atmosphere. The filter module includes a cyclone dust collector 500, which is connected to the air inlet of the air conditioning module 400.

[0035] The outer casing 100 forms the main frame of the charging pile, featuring dustproof, waterproof, and impact-resistant properties. The charging module 200, as the primary heat source during charging, internally contains key components such as an AC / DC power supply, rectifier, DC-DC / AC-DC converter, IGBT power module, and inductor. The air-cooling process directly directs low-temperature air to the charging module 200, enabling efficient heat exchange between the cold air and the surfaces of the high-temperature components, thereby controlling the temperature of the charging module 200. The charging module 200 has a cold air inlet 210 and a hot air outlet 220 on its two sides. Multiple intake fans can be added to the cold air inlet 210, actively drawing cold air into the charging module 200. After heat exchange with the heat sink of the charging module 200, the cold air is discharged from the hot air outlet 220, preventing hot air recirculation from affecting the air-cooling efficiency.

[0036] The air conditioning module 400 can cool the outside air to a set temperature through a compressor or heat pump system, forming cold air that is then delivered into the air duct 300 and subsequently into the charging module 200. Preferably, the air conditioning module 400 can dynamically adjust its cooling capacity according to the temperature of the charging module 200. When the temperature of the charging module 200 is too high (due to high-power charging or excessively high ambient temperature), the air conditioning module 400 operates to deliver cold air to the charging module 200. Preferably, when the temperature of the charging module 200 does not reach the threshold (due to low-power charging or low ambient temperature), the air conditioning module 400 does not operate and the air is directly cooled by air from the outside environment.

[0037] The filter module is used to filter the air to prevent dust (especially metal dust) from entering the charging module 200 and causing a short circuit. The cyclone dust collector 500 in the filter module uses centrifugal force to separate dust particles. Dust-laden air enters the cyclone dust collector 500 and forms a high-speed rotating airflow. The dust particles are separated from the air due to centrifugal force, and the clean air enters the air conditioning module 400. Since the cyclone dust collector 500 does not experience a decrease in air intake due to dust blockage during operation, it can ensure extremely high air-cooling efficiency.

[0038] It is important to note that charging power is a key performance indicator of a charging station; higher power means shorter charging time and greater economic benefits. However, during high-power charging, the charging module 200 generates a significant amount of heat, causing its temperature to rise dramatically. If heat cannot be dissipated in time, this can lead to safety hazards such as fires. Therefore, a prerequisite for achieving high-power charging is the installation of an efficient and reliable cooling system.

[0039] The efficiency of an air-cooled system directly depends on the airflow and temperature. However, in industrial areas, mining areas, dusty regions, and high-temperature environments (such as Xinjiang in summer), traditional air-cooled charging stations struggle to meet the demands of high-power charging. On one hand, excessively high ambient temperatures prevent effective heat exchange between the air and the charging module, resulting in extremely low air-cooling efficiency and an inability to remove the heat generated during high-power charging. On the other hand, dusty air easily clogs the filtration system, causing a sharp drop in airflow and reducing the cooling effect. Reducing airflow to protect the filtration system will also negatively impact cooling efficiency due to insufficient airflow.

[0040] Therefore, to achieve sustainable high-power charging, the air-cooling system must be able to continuously provide low-temperature, high-flow-rate cooling air under high-temperature and high-dust conditions, while keeping the filter channel 600 unobstructed to ensure that heat dissipation performance does not decrease. During charging, the cyclone dust collector 500 and the air conditioning module 400 work together to dissipate heat from the charging module 200. In the specific air-cooling process: outside air passes through the cyclone dust collector 500 to remove dust. Since the cyclone dust collector 500 has no filter clogging issues, it can achieve the purpose of high-flow-rate air filtration, which is extremely important. The purified air enters the air conditioning module 400, which cools the air to the set temperature and delivers the cold air to the charging module 200 through the air duct 300. Regardless of the outside temperature, it can provide stable cold air, and the exhaust vent of the air conditioning module 400 can expel hot air from the outer casing 100. The cold air contacts the charging module 200, thus carrying away heat, and the hot air exhausted from the charging module 200 is discharged from the casing through the hot air outlet 220. The above-mentioned air-cooling method can effectively achieve the purpose of high-power charging. The cyclone dust collector 500 can efficiently remove dust while maintaining a large airflow. The airflow will not decrease throughout the entire service life, so the air-cooling efficiency will not drop. The filtered air passes through the air conditioning module 400 to form cold air, which is then directly introduced into the charging module 200 for heat exchange, eliminating the restriction of the external environment on the air-cooling efficiency.

[0041] Based on the above embodiments, it also includes an exhaust module 700, and the charging module 200 also has a hot air outlet 220, with the exhaust module 700 connected to the hot air outlet 220.

[0042] Cool air enters the charging module 200 through the cold air inlet 210. After heat exchange with the charging module 200, hot air is formed and exits the charging module 200 through the hot air outlet 220. Connected to the hot air outlet 220 is the exhaust module 700, which is used to forcibly expel the hot air, allowing it to quickly leave the outer casing 100. The exhaust module 700 actively exhausts the hot air using a fan, which, compared to natural convection cooling, effectively improves the heat exchange rate and prevents hot air from accumulating inside the outer casing 100.

[0043] like Figures 1 to 5 , Figures 8 to 10 As shown, based on the above embodiment, the outer casing 100 includes a cabinet 110, a first cabinet door 120 and a second cabinet door 130. The first cabinet door 120 and the second cabinet door 130 are respectively hinged to both sides of the cabinet 110. The charging module 200 and the air duct 300 are both installed inside the cabinet 110. The air conditioning module 400 is installed in the first cabinet door 120, the exhaust module 700 is installed in the second cabinet door 130, and the filter module is installed on the top of the cabinet 110.

[0044] The air conditioning module 400 is directly installed in the first cabinet door 120, which is close to the cold air inlet of the charging module 200, shortening the cold air delivery path and reducing wind resistance. The door design also facilitates the daily maintenance and replacement of the air conditioning module 400. The exhaust module 700 is installed in the second cabinet door 130, which connects with the hot air outlet 220 of the charging module 200 to form a convection cooling path. The door design also facilitates the daily maintenance and replacement of the exhaust module 700. The air conditioning module 400 and the exhaust module 700 are installed in the two cabinet doors respectively, forming a modular layout. The filter module is installed on the top of the cabinet 110, which effectively utilizes the internal space of the outer shell 100, resulting in a compact layout for the charging station.

[0045] Based on the above implementation, the air conditioning module 400 is an industrial air conditioner. The first cabinet door 120 has a mounting cavity 121, and the industrial air conditioner is embedded in the mounting cavity 121. The inner wall of the first cabinet door 120 has a first hollow area 122 and a second hollow area 123, and the outer wall of the first cabinet door 120 has a third hollow area 124. The first hollow area 122, the second hollow area 123, and the third hollow area 124 are all connected to the mounting cavity 121. The air outlet of the industrial air conditioner is aligned with the first hollow area 122, the air inlet of the industrial air conditioner is aligned with the second hollow area 123, and the air exhaust outlet of the industrial air conditioner is aligned with the third hollow area 124.

[0046] The cool air generated by the industrial air conditioner is directly delivered into the air duct 300 through the first perforated area 122. The second perforated area 123 is used to introduce purified air, and the third perforated area 124 faces outward, through which waste heat generated during air conditioner operation is discharged to the external environment. The industrial air conditioner is embedded in the mounting cavity 121 of the first cabinet door 120. After the industrial air conditioner is installed, its air inlet, air outlet, and exhaust outlet are aligned with the corresponding perforated areas. It does not need to be directly connected to the air duct 300 or the filter module, but is connected through the perforated areas with fixed positions, which greatly reduces the assembly difficulty.

[0047] Based on the above implementation method, the position of the first cabinet door 120 includes an open position and a closed position; when the first cabinet door 120 is in the open position, the first hollow area 122 is offset from the inlet of the air duct 300, and the second hollow area 123 is offset from the filter module; when the first cabinet door 120 is in the closed position, the first hollow area 122 is connected to the inlet of the air duct 300, and the second hollow area 123 is connected to the filter module.

[0048] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 , Figure 9As shown, based on the above-described embodiment, the ventilation module 700 includes a plurality of exhaust fans 710 arranged in an array, and each exhaust fan 710 is installed on the second cabinet door 130.

[0049] The exhaust fan 710 generates negative pressure by rotating its blades at high speed, which quickly exhausts the hot air blown out of the hot air outlet 220 into the outer casing 100.

[0050] like Figures 1 to 5 As shown, based on the above implementation method, the air duct 300 is a flared structure with one large port and the other small port. The large port of the air duct 300 is connected to the cold air inlet 210, and the small port of the air duct 300 is connected to the air outlet of the air conditioning module 400.

[0051] The flared structure of the air duct 300 accelerates the airflow speed through a tapering design (from the large port to the small port), utilizing the Venturi effect (fluid velocity increases and pressure decreases in a narrow cross-section) to enhance the kinetic energy of the airflow within the air duct 300. After entering from the large port, the cold air is accelerated through the narrow small port, forming a high-pressure, high-speed airflow that directly acts on the cold air inlet 210 of the charging module 200. This effectively increases the wind speed of the cold air, thereby improving the air-cooling effect.

[0052] like Figures 1 to 7 As shown, based on the above implementation method, the filter module also includes a filter channel 600 and a fine filter element. The two ends of the filter channel 600 are respectively connected to the air inlet of the cyclone dust collector 500 and the air conditioning module 400, and the fine filter element is installed in the filter channel 600.

[0053] The fine filter element is preferably a filter screen or filter cotton. The cyclone dust collector 500 plays a pre-filtration role. The air pre-filtered by the cyclone dust collector 500 still needs to be filtered a second time by the fine filter element to remove the remaining dust in the air. Since the cyclone dust collector 500 has already filtered out most of the dust during pre-filtration, the fine filter element is not easy to clog, providing a reliable structural basis for large-flow air intake.

[0054] like Figures 1 to 7 As shown, based on the above embodiments, the cyclone dust collector 500 includes a dust collector housing 510, a negative pressure suction pipe 520, and at least one centrifugal separation unit 530. The dust collector housing 510 is provided with an independent air inlet chamber 511, a negative pressure chamber 512 and a dust collection chamber 513, and the negative pressure suction pipe 520 is connected to the negative pressure chamber 512. The centrifugal separation unit 530 includes an air inlet pipe 531 and an exhaust pipe 532. The inlet of the air inlet pipe 531 is connected to the air inlet chamber 511, and the outlet of the air inlet pipe 531 is connected to the dust collection chamber 513. The end of the air inlet pipe 531 near the dust collection chamber 513 is configured as a conical cavity structure with a diameter that gradually decreases in the direction of the dust collection chamber 513. A part of the exhaust pipe 532 is inserted into the inlet of the air inlet pipe 531. The inlet of the exhaust pipe 532 is connected to the inside of the air inlet pipe 531, and the outlet of the exhaust pipe 532 is connected to the negative pressure chamber 512. A spiral guide vane 533 is provided between a part of the outer wall surface of the exhaust pipe 532 and the inner wall surface of the air inlet pipe 531.

[0055] The negative pressure chamber 512, the air inlet chamber 511, and the dust collection chamber 513 are arranged sequentially from top to bottom and are isolated from each other. The wall of the dust collector housing 510 corresponding to the air inlet chamber 511 has an air inlet (micropore), allowing external air to enter the air inlet chamber 511 through the air inlet. The negative pressure suction pipe 520 extends upward from the bottom of the dust collector housing 510 into the negative pressure chamber 512. The top end of the negative pressure suction pipe 520 is connected to the negative pressure chamber 512, and the bottom end of the negative pressure suction pipe 520 is connected to the inlet of the filter channel 600. A negative pressure generating source (such as a vacuum pump or induced draft fan) can be installed in the filter channel 600. The negative pressure generating source creates a negative pressure in the negative pressure suction pipe 520 and the negative pressure chamber 512. Since the top end of the exhaust pipe 532 is connected to the negative pressure chamber 512, the lower port of the exhaust pipe 532 (located in the air inlet pipe 531) forms a negative pressure area, driving the airflow. The spiral guide vane 533 is arranged along a spiral involute, which can effectively guide the airflow between the intake pipe 531 and the exhaust pipe 532 to rotate. The centrifugal force during rotation separates the dust. The air after removing the dust can enter the negative pressure chamber 512 through the exhaust pipe 532 and enter the filter channel 600 through the negative pressure suction pipe 520. The dust falls into the dust collection chamber 513.

[0056] The working mechanism of the cyclone dust collector 500 is as follows: External air enters the intake chamber 511 through the air inlet. Due to the suction force created by the negative pressure at the lower end of the exhaust pipe 532, the air in the intake chamber 511 is drawn into the area between the intake pipe 531 and the exhaust pipe 532 through the upper port of the intake pipe 531. The flowing air rotates after passing through the spiral guide vane 533. Utilizing the centrifugal force generated by the rotating airflow, denser solid particles (dust) are thrown against the inner wall of the conical cavity structure of the intake pipe 531 under the action of strong centrifugal force. After colliding with the inner wall, the dust loses kinetic energy and slides down the inner wall of the conical cavity structure of the intake pipe 531 under the action of gravity, eventually falling into the dust collection chamber 513 at the bottom, thereby separating the denser solid particles from the gas. The purified air then enters the negative pressure chamber 512 through the exhaust pipe 532 and enters the filter channel 600 through the negative pressure suction pipe 520.

[0057] It should be further explained that the lower end of the air inlet pipe 531 has a conical cavity structure. This design allows the rotation radius of the rotating airflow to gradually decrease. According to the conservation of angular momentum, the rotation speed of the airflow will increase sharply, thereby generating a greater centrifugal force, which will separate even finer particles. At the same time, it ensures that the separated particles are guided to the dust collection bin 513.

[0058] It is important to note here that the Cyclone Dust Collector 500 not only ensures that the filter module is not clogged by dust while maintaining a large airflow, but also effectively removes most of the metal dust in the air. This effectively prevents metal dust from entering the charging pile with the air and adhering to the circuit board surface, ensuring the safe operation of the charging pile.

[0059] like Figures 1 to 5 , Figure 9 , Figure 10 As shown, based on the above embodiment, a module compartment 111 is installed inside the outer casing 100, and a charging module 200 is installed inside the module compartment 111. Both ends of the module compartment 111 have openings, and the cold air inlet 210 and the hot air outlet 220 are located at the two openings of the module compartment 111, respectively.

[0060] Cold air enters from one end, flows through the charging module 200, and exits from the other end, forming a unidirectional, straight airflow channel, reducing eddies and pressure loss caused by airflow bends. The cold air inlet 210 and the hot air outlet 220 are located at opposite ends of the module compartment 111, with clear spatial isolation to prevent the exhaust high-temperature gas from being re-inhaled.

[0061] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0062] Furthermore, in this utility model, descriptions involving "first," "second," or "a" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0063] In this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components, unless otherwise explicitly limited.

[0064] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
