Description

Technical Field

[0001] This utility model relates to the field of air-cooling technology, and in particular to an air-cooling system and a charging pile. Background Technology

[0002] When the power modules inside the charging pile are in operation, they generate a lot of heat. This heat needs to be effectively ventilated and dissipated. If the heat accumulates inside the cabinet and cannot be effectively dissipated, it will seriously threaten the operation of the power modules. Excessive temperature will burn out the power modules, or there is a risk of fire or even explosion due to high temperature.

[0003] Currently, most charging piles on the market use direct ventilation to dissipate heat from the power modules inside the charging pile and remove the heat accumulated inside the cabinet. This heat dissipation method has limited dust protection capabilities when used outdoors, and dust or water entering the power modules inside the charging pile can easily lead to poor heat dissipation or even cause the charging pile to malfunction.

[0004] Therefore, how to provide an air-cooled system and charging station to improve the above-mentioned drawbacks is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0016] Preferably, the air outlet panel includes:

[0017] The third housing is equipped with an air inlet;

[0018] The fourth housing is connected to the third housing and together with the third housing forms an air outlet channel. The fourth housing is provided with an air outlet for fluid to flow out.

[0019] Preferably, the power source is a centrifugal fan, and the air outlet assembly also includes a mounting plate disposed between the air inlet and the air outlet.

The fluid enters along the air inlet door of the air inlet component. The air outlet component and the air inlet component are arranged opposite each other to improve the fluid flow efficiency, thereby improving the cooling efficiency of the heat source inside the cabinet. By installing a baffle in the air inlet door of the air inlet component, the fluid flowing into the air inlet channel is turned around the baffle.

The separated fluid enters the cabinet through the fluid outlet, blocking liquids and dust that are not easy to turn, so as to prevent liquids and dust from contacting the heat-generating and electrical components inside the cabinet.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0037] The purpose of this invention is to provide an air-cooled system and charging pile that can improve fluid flow efficiency and cooling efficiency of heat sources; it can also prevent liquids and dust that are difficult to turn from coming into contact with heat-generating and electrical components inside the cabinet.

[0038] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, and the Y direction is defined as the second direction. The first direction and the second direction are perpendicular to each other.

[0039] Please see Figures 1 to 4 To achieve the above objectives, this utility model provides an air-cooled system installed in the cabinet 100 of a charging pile. The system includes an air inlet assembly 200 and an air outlet assembly 300. The air inlet assembly 200 is disposed on one side of the cabinet 100 in a first direction. The air inlet assembly 200 includes an air inlet door panel 210 and a baffle 220. The air inlet door panel 210 has a fluid inlet, a fluid outlet, and a U-shaped air inlet channel 230 located between the fluid inlet and the fluid outlet. The baffle 220 is located within the air inlet channel 230 to allow fluid flowing into the air inlet channel 230 along the fluid inlet. The fluid is deflected around the baffle 220, causing dust and water droplets in the fluid to be deposited in the air inlet channel 230. After separation, the fluid enters the cabinet 100 through the fluid outlet. The air outlet assembly 300 is located on the other side of the cabinet 100 in the first direction and corresponds to the air inlet assembly 200. The air outlet assembly 300 includes an air outlet door 310 and a power source 320. The air outlet door 310 is provided with an air outlet channel 314 that communicates with the inside of the cabinet 100. The power source 320 can drive the fluid located inside the cabinet 100 to flow out of the cabinet 100 through the air outlet channel 314.

[0040] An air inlet assembly 200 and an air outlet assembly 300 are arranged on both sides of the cabinet 100 in the first direction. The power source 320 of the air outlet assembly 300 can drive the fluid inside the cabinet 100 to flow out of the cabinet 100 along the air outlet channel 314, so that the inside of the cabinet 100 is in a negative pressure environment, so that the fluid can enter along the air inlet door 210 of the air inlet assembly 200. The air outlet assembly 300 and the air inlet assembly 200 are arranged opposite to each other to improve the fluid flow efficiency, thereby improving the cooling efficiency of the heat source inside the cabinet 100. By installing a baffle 220 inside the air inlet door plate 210 of the air inlet assembly 200, the fluid flowing into the air inlet channel 230 is redirected around the baffle 220. The air inlet channel 230 is U-shaped, which allows for a wide range of fluid deflection and causes dust and water droplets in the fluid to settle inside the air inlet channel 230. The separated fluid then enters the cabinet 100 through the fluid outlet, blocking liquids and dust that are difficult to deflect, thus preventing liquids and dust from contacting the heat-generating and electrical components inside the cabinet 100. This also avoids the problem of excessive noise from the entire unit caused by direct ventilation.

[0041] In this embodiment, the air inlet door panel 210 includes a first housing 211 with a fluid inlet and a second housing 212 with a fluid outlet. The first housing 211 has sidewalls extending toward the second housing 212 at both ends in the second direction to connect to the second housing 212. The baffle 220 is a plate structure extending in the second direction, and the baffle 220 is spaced apart from the two sidewalls, so that the fluid can flow around the baffle 220 on both sides in the second direction into the cabinet 100. The bottom and top of the baffle 220 can be fixed to the top and bottom of the first housing 211, and the baffle 220 is directly opposite the fluid inlet and the fluid outlet. By increasing the size of the fluid inlet and the fluid outlet, more gas can enter the cabinet 100, achieving a better cooling effect. The cross-sectional area of ​​the baffle 220 perpendicular to the first direction is larger than the cross-sectional area of ​​the fluid inlet and the fluid outlet perpendicular to the first direction. That is, the projected area of ​​the first inlet and the first outlet along the first direction is smaller than the projected area of ​​the baffle 220 along the first direction, which can ensure a better anti-direct current effect and reduce the fluid flow rate to reduce noise.

[0042] A first filter screen 214 is installed at the fluid inlet to initially intercept large particles of willow catkins, cotton fibers, dust, and raindrops. A filter cotton 215 is installed at the fluid outlet. The fluid passes through the filter cotton 215 and enters the cabinet 100 to further block small particles of impurities, preventing damage to electrical components inside the cabinet 100 and improving the service life of electrical components. The first filter screen 214 can be made of steel wire mesh, which has high strength and is corrosion resistant. The filter cotton 215 can be made of 35PPI filter cotton, which has excellent air permeability, good softness, and high mechanical strength. Multiple filter cotton 215 pieces can be used and fixed to different openings of the second housing 212. While ensuring the opening area, the stability of the filter cotton 215 after installation can be improved by arranging them vertically.

[0043] There is a gap between the baffle 220 and the fluid inlet and fluid outlet in the first direction, and a first diverter plate 250 is connected to the middle of the baffle 220 and the middle of the fluid inlet. The first diverter plate 250 is perpendicular to the second direction, so that the fluid entering the air inlet channel 230 along the fluid inlet is divided into two parts. The fluid is slowed down and turned by the baffle 220 and flows along the two ends of the baffle 220 in the second direction. This can avoid the fluid velocity from being too fast and generating a lot of noise. At the same time, the diversion avoids the problem of turbulence caused by the fluid all gathering on one side of the baffle 220. The gap between the baffle 220 and the fluid outlet can form a buffer area for the fluid to mix, thereby avoiding the phenomenon of large local flow velocity differences before the fluid enters the cabinet 100, and thus improving the overall cooling of the heat source by the fluid entering the cabinet 100.

[0044] In one embodiment, the air inlet assembly 200 further includes a guide plate 240, which is located at one end of the baffle 220 in the second direction and is spaced apart from the baffle 220 and the side wall. The guide plate 240 includes a first guide section 241, a second guide section 242, and a connecting section 243. The first guide section 241 is located between the baffle 220 and the fluid inlet, the second guide section 242 is located between the baffle 220 and the fluid outlet, and the connecting section 243 connects the first guide section 241 and the second guide section 242 in the same guide plate 240. By setting the guide plate 240, the flow of fluid can be guided to avoid turbulence. The guide plate 240 can also block the fluid to a certain extent to reduce the flow rate and avoid excessive noise caused by excessive flow rate. After passing through the baffle 220 and the guide plate 240, the airflow direction changes 180°. Unblocked water droplets and dust are thrown onto the guide plate 240 by centrifugal force, settle along the wall to the bottom of the air inlet channel 230, and are discharged from the air inlet assembly 200 through the bottom inclined discharge surface.

[0045] In one embodiment, two guide vanes 240 are provided, and the two guide vanes 240 are symmetrically arranged at both ends of the baffle 220 in the second direction. A first flow channel is formed between the guide vanes 240 and the side of the baffle 220 facing each other, and a second flow channel is formed between the guide vanes 240 and the sidewall facing each other. That is, through the arrangement of the first diverter 250 and the two guide vanes 240, the entire air inlet channel 230 is divided into two first flow channels and two second flow channels. The two guide vanes 240 are symmetrically arranged at both ends of the baffle 220 in the second direction, and the fluid inlet is at the second end. The upward width is twice the distance between the two opposing ends of the first guide sections 241 in the second direction; the width of the fluid outlet in the second direction is twice the distance between the opposing ends of the two second guide sections 242 in the second direction, so that the fluid is divided into four equal parts after entering the fluid inlet. Each part of the fluid flows along its corresponding first or second flow channel to the corresponding four-part position at the fluid outlet and enters the cabinet 100. This setting makes the fluid entering the cabinet 100 more uniform, which facilitates the overall cooling of the heat source inside the cabinet 100 and improves the heat dissipation effect.

[0046] It should be noted that the deflector 240 is in a flared U-shaped structure, and the distance between the first flow guide section 241 and the baffle 220 gradually decreases along the fluid flow direction, that is, the first flow guide section 241 is an inclined plate body arranged at an angle to the second direction, and the first flow guide section 241 is inclined toward one end of the baffle 220 in the second direction. The distance between the second flow guide section 242 and the baffle 220 gradually increases along the fluid flow direction, that is, the second flow guide section 242 is an inclined plate body arranged at an angle to the second direction, and the second flow guide section 242 is inclined toward one end of the baffle 220 in the second direction, so that the fluid presents a "several"-shaped flow path in both the first flow channel and the second flow channel, which can guide the advancing direction of the fluid, so that the fluid that has not been decelerated by the baffle 220 flows along a longer path around the outer sides of the first flow guide section 241 and the second flow guide section 242, so as to achieve a certain deceleration effect on the fluid and reduce phenomena such as noise caused by excessive flow velocity.

[0047] To avoid excessive noise generated by part of the fluid that has not been decelerated by the baffle 220 in the second flow channel, the opposite sides of the two side walls are provided with first sound insulation cotton 213. Through the guidance of the deflector 240, the fluid comes into contact with the side walls, and the arrangement of the first sound insulation cotton 213 can reduce the noise generated when the fluid flows in the second flow channel. A second sound insulation cotton 221 is installed on the side of the baffle 220 facing the inside of the cabinet 100 in the first direction, which also achieves the effect of reducing noise for the fluid in the first flow channel.

[0048] In this embodiment, the air outlet door panel 310 includes a third housing 311 and a fourth housing 312. The third housing 311 is provided with an air inlet 313; the fourth housing 312 is connected to the third housing 311, and cooperates with the third housing 311 to form an air outlet flow channel 314. The fourth housing 312 is provided with an air outlet for fluid to flow out. The power source 320 is a centrifugal fan, and the air outlet assembly 300 further includes a mounting plate 330 disposed between the air inlet 313 and the air outlet. The mounting plate 330 can be connected to the top and / or bottom of the third housing 311, and the centrifugal fan is assembled on the side of the mounting plate 330 facing the air inlet 313. The centrifugal fan is configured to pressurize the fluid entering the air outlet flow channel 314 along the air inlet 313 and then flow the fluid to both sides of the centrifugal fan in the second direction.

[0049] Wherein, both the air inlet door panel 210 and the air outlet door panel 310 are integrally formed, which can improve the strength of the air inlet door panel 210 and the air outlet door panel 310, avoid the gap generated by the assembly of the first housing 211 and the second housing 212, further prevent the fluid from entering the inside of the cabinet 100 without passing through the filter cotton 215 and damaging the electrical elements, and at the same time avoid the gap generated by the assembly of the third housing 311 and the fourth housing 312, thereby ensuring that the gas can be smoothly discharged along the air outlet flow channel 314.

[0050] The air inlet 313 is located on the side of the third housing 311 away from the fourth housing 312, and is located in the middle of the third housing 311 in the second direction, so that the gas gathers at the air inlet 313. By setting the mounting plate 330 between the air inlet 313 and the air outlet, and with the mounting plate 330 facing the air inlet 313, the gas at the air inlet 313 is pressurized by the centrifugal fan and discharged to both ends of the centrifugal fan in the second direction to form a high-pressure environment. Then, in this high-pressure environment... The gas is discharged along the side of the mounting plate 330 away from the air inlet 313 to the air outlet, expelling the gas that has exchanged heat with the heat source, thereby achieving the effect of cooling the heat source inside the cabinet 100. A second filter screen 317 is installed at the air outlet of the air outlet door plate 310 to prevent impurities in the fluid outside the cabinet 100 from entering the cabinet 100 along the air outlet channel 314 when the centrifugal fan is not running. In addition, the mounting plate 330 is also directly opposite the air outlet, which plays the role of isolating noise and blocking water to improve the protective performance.

[0051] In this embodiment, it is understood that the gas pressurized by the centrifuge has a high flow velocity. By providing third sound insulation cotton 315 on both sides of the third housing 311 in the second direction and located in the air outlet 314, the noise generated by the high-pressure gas can be reduced. During the flow of the gas in the high-pressure environment to the low-pressure air outlet, it still has a high flow velocity. In order to avoid noise generated by the collision between the gas and the fourth housing 312 during the flow, a fourth sound insulation cotton 316 is provided on the side of the fourth housing 312 facing the third housing 311, and one end of the fourth sound insulation cotton 316 and the third sound insulation cotton 315 are connected. A second diversion plate 340 is provided between the mounting plate 330 and the second filter screen 317. The second diversion plate 340 is perpendicular to the second direction, so that the air outlet 314 is divided into two flow paths, which can prevent the high-pressure gas from bypassing the mounting plate 330 and causing convection, thereby improving the efficiency of gas outflow.

[0052] Multiple centrifugal fans can be used, and all centrifugal fans can be detached and installed on the mounting plate 330. They are evenly arranged along the height direction of the mounting plate 330, which is perpendicular to the first and second directions. This results in higher air pressure from the centrifugal fans, making it easier to select a filtration system. At the same time, all centrifugal fans are arranged vertically, allowing for flexible configuration of the number of centrifugal fans according to different heat dissipation requirements. Furthermore, by starting and stopping centrifugal fans at different heights, heat sources at different heights within the cabinet 100 can be cooled to varying degrees, making it more efficient and energy-saving, thereby reducing air cooling costs.

[0053] Furthermore, this application also provides a charging pile, including a cabinet 100 and the aforementioned air-cooling system; a power module is installed inside the cabinet 100 to ensure the normal operation of the charging pile. The power module generates heat when outputting, and its location inside the cabinet 100 causes heat accumulation. An air intake assembly 200 is installed on one side of the cabinet 100, and an air outlet assembly 300 is installed on the other side. The air outlet assembly 300 includes a centrifugal fan for driving the air inside the cabinet 100 out of the cabinet 100. When the centrifugal fan is started, the air inside the cabinet... After the gas inside the body 100 is pressurized, it is discharged to both sides of the centrifugal fan to form a high-pressure environment and flows into the low-pressure air outlet channel 314 to exit the cabinet 100, so that the cabinet 100 is in a negative pressure environment. This allows the fluid on the side of the air inlet component 200 to flow in along the air inlet channel 230. Under the action of the baffle 220, the direct flow of the fluid is prevented, so that the fluid flowing into the air inlet channel 230 is turned around the baffle 220. This blocks liquids and dust that are not easy to turn, so as to prevent liquids and dust from contacting the heat-generating and electrical components inside the cabinet 100, thereby improving the service life of the charging pile.

[0054] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0055] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0056] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
