[0002] With the rapid development of electric vehicles, the demand for charging piles is growing, and the charging power of charging piles is constantly increasing, from the initial 20KW to today's 1000KW super charging. As the charging power increases, the heat generated by the power module inside the charging pile also increases sharply. In order to ensure the stable operation of the equipment, existing charging piles usually use a large number of large fans to dissipate heat. However, due to the increase in the number of fans in the equipment, this heat dissipation method produces very loud noise, and the close-range noise generally exceeds 100 decibels, which brings serious noise problems. However, charging pile equipment is often installed in densely populated areas. In these scenarios, the noise of the charging pile will have a great impact on the living environment.

[0004] In a first aspect, an embodiment of the present invention provides a method for heat dissipation of a charging pile, the method comprising:

[0005] A first pressure difference is generated by releasing a first airflow through an air outlet of a first ventilation duct on a target charging pile, and the air outlet of the first ventilation duct can release airflow toward the interior of a pile body of the target charging pile. The first airflow is an airflow that is pressurized and introduced into the first ventilation duct on the target charging pile. The first pressure difference is a pressure difference formed on the inner and outer sides of an air inlet of the target charging pile by the first airflow and the second airflow released through the air outlet of the first ventilation duct. The inner and outer sides of the air inlet are a side facing the exterior of the pile body of the target charging pile and a side facing the interior of the pile body of the target charging pile at the air inlet of the target charging pile. The second airflow is a natural wind close to the air inlet of the target charging pile and located outside the pile body of the target charging pile.

[0006] Based on the first pressure difference, driving the second airflow to be pressed into the pile body of the target charging pile from the air inlet of the target charging pile to drive the third airflow to flow, wherein the third airflow includes the airflow inside the pile body of the target charging pile;

[0007] The heat generated inside the pile body of the target charging pile is discharged through the third airflow flowing inside the pile body of the target charging pile.

[0008] In a second aspect, an embodiment of the present invention further provides a charging pile heat dissipation processing device, the device comprising:

[0009] A first processing module, for releasing a first airflow through an air outlet of a first ventilation duct on a target charging pile to generate a first pressure difference, the air outlet of the first ventilation duct can release airflow toward the interior of a pile body of the target charging pile, the first airflow is an airflow that is pressurized and introduced into the first ventilation duct on the target charging pile, the first pressure difference is a pressure difference formed on the inner and outer sides of an air inlet of the target charging pile by the first airflow released through the air outlet of the first ventilation duct and the second airflow, the inner and outer sides of the air inlet being a side facing the outside of the pile body of the target charging pile at the air inlet of the target charging pile and a side facing the inside of the pile body of the target charging pile, the second airflow is a natural wind close to the air inlet of the target charging pile and located outside the pile body of the target charging pile;

[0010] a second processing module, configured to drive the second airflow from the air inlet of the target charging pile into the interior of the pile body of the target charging pile based on the first pressure difference to drive a third airflow to flow, wherein the third airflow includes an airflow inside the pile body of the target charging pile;

[0011] The third processing module is used to discharge the heat generated inside the pile body of the target charging pile through a third airflow flowing inside the pile body of the target charging pile.

[0012] In a third aspect, an embodiment of the present invention further provides an electronic device, the electronic device comprising:

[0013] at least one processor; and

[0014] a memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores a computer program that can be executed by the at least one processor, and the computer program is executed by the at least one processor so that the at least one processor can execute the charging pile heat dissipation processing method described in any one of the above embodiments.

[0016] In a fourth aspect, an embodiment of the present invention further provides a computer-readable medium, wherein the computer-readable medium stores computer instructions, and the computer instructions are used to enable a processor to implement the charging pile heat dissipation processing method described in any one of the above embodiments when executed.

[0017] According to the technical solution of the embodiment of the present invention, the air outlet of the first ventilation duct on the target charging pile can release airflow toward the interior of the pile body of the target charging pile. When the first airflow is pressurized and introduced into the first ventilation duct on the target charging pile, it will be further released into the interior of the pile body of the target charging pile through the air outlet of the first ventilation duct. Since the first airflow is a pressurized airflow, it will have a certain kinetic energy and pressure. When the first airflow is released toward the interior of the pile body, it will not only generate a higher airflow movement speed itself but also be able to quickly mix with the air inside the pile body, thereby increasing the airflow movement speed inside the pile body near the air inlet of the target charging pile. According to the idea that the greater the wind speed and the smaller the fluid pressure indicated by the Bernoulli fluid principle, the first airflow and the second airflow near the air inlet and located outside the pile body form a first pressure difference on the inside and outside of the air inlet. It is not difficult to see that since the pressure difference is generated after the first airflow is released, the problem of large noise caused by using a fan or other equipment to blow air into the interior of the pile body to promote airflow movement is avoided. A large pressure difference can be generated by releasing the pressurized airflow inside the pile body through the first ventilation duct. Furthermore, the second airflow is pressed into the interior of the pile body through the first pressure difference, and then the third airflow including the airflow inside the pile body is driven to flow. During the flow of the third airflow inside the pile body, it can fully contact the heat-generating components to discharge the heat, thereby ensuring sufficient heat dissipation of the charging pile equipment and reducing equipment noise.

[0033] Figure 1A flow chart of a method for heat dissipation of a charging pile provided in an embodiment of the present invention. The technical solution of the embodiment of the present invention is applicable to the case of dissipating heat from a charging pile. The method can be performed by a heat dissipation device for a charging pile. The heat dissipation device for a charging pile can be implemented in the form of software and / or hardware and is generally integrated in any electronic device with network communication function, which can be a mobile terminal, a PC or a server, etc.

[0034] like Figure 1 As shown, the heat dissipation processing method of the charging pile in the embodiment of the present invention may include the following process:

[0035] S110. A first pressure differential is generated by releasing a first airflow through an air outlet of a first ventilation duct on a target charging pile. The air outlet of the first ventilation duct can release airflow toward the interior of a pile body of the target charging pile. The first airflow is an airflow that is pressurized and introduced into the first ventilation duct on the target charging pile. The first pressure differential is a pressure difference formed at the inner and outer sides of an air inlet of the target charging pile by the first airflow released through the air outlet of the first ventilation duct and the second airflow. The inner and outer sides of the air inlet are a side facing the outside of the pile body of the target charging pile and a side facing the inside of the pile body of the target charging pile at the air inlet of the target charging pile. The second airflow is a natural wind that is close to the air inlet of the target charging pile and is located outside the pile body of the target charging pile.

[0036] A charging pile is a device that provides electric energy for electric vehicles. It is usually installed in parking lots, gas stations, commercial areas, residential areas and other places. It converts AC or DC electricity into a current and voltage suitable for charging electric vehicle batteries by connecting to the power grid, and connects to the electric vehicle through the charging interface to charge the battery of the electric vehicle. Among them, the charging pile can support different charging modes, such as fast charging and slow charging. The fast charging mode can provide a large amount of electricity to the electric vehicle in a short time, while the slow charging mode charges at a lower power, which has less impact on the battery life and is suitable for charging when parked for a long time. The target charging pile can be a charging pile with heat dissipation requirements.

[0037] The body of the charging pile is usually composed of a shell made of strong and durable materials, such as metal or high-strength plastic, which can withstand the test of various environmental conditions, such as sun, rain, wind, etc. At the same time, the shell design corresponding to the body of the charging pile also takes into account the protective performance, with a certain degree of waterproof, dustproof and impact-proof capabilities to ensure the safe operation of the internal electrical components.

[0038] The power module inside the charging pile body will generate a lot of heat during operation. In order to ensure the stable operation of the charging pile, it is necessary to add a very large cooling fan or a powerful fan to dissipate heat. For example, the heat dissipation solution of the charging pile is as follows, using a large number of cooling fans or powerful fans to extract or blow out hot air inside the charging pile body to dissipate heat. However, these solutions have some problems. On the one hand, they need to consume a lot of electricity from the charging pile, and at the same time, the high-speed operation of the fan will generate very loud equipment noise. Although it can effectively bring out the heat inside the equipment to cool the equipment and ensure that the charging pile can always remain in a suitable temperature range during operation, it will generate a lot of equipment noise, which is not worth the loss.

[0039] For example, see Figure 2 , shows a simulation diagram of the cooling air flow of the charging pile. The charging pile body is provided with cooling ports on both sides, and a fan is provided on one side of the charging pile. The fan draws air from the inside of the charging pile body to the outside through the cooling ports. When the fan is running, the strong suction force allows the hot air inside the charging pile body to be quickly drawn out. On the other side of the charging pile, there are also cooling holes. These cooling holes have the function of air intake, and then the heat inside the equipment is brought out through the flow of wind, and the relatively cool air from the outside enters the charging pile through the cooling holes to cool the equipment.

[0040] See also Figure 3 , unfold the air inlet and outlet doors of the target charging pile. The air inlet and outlet doors connected to the charging pile body through the rotating shaft can be flipped open and closed around the rotating shaft along the direction of the blue arrow on both sides of the charging pile body. Figure 3 The schematic diagram is a state diagram that can be presented after the air inlet door and the air outlet door are opened and unfolded around the rotation axis on both sides of the pile body of the target charging pile. There are several air inlets distributed on the air inlet door of the target charging pile, and there are several exhaust outlets distributed on the air outlet door of the target charging pile. The several air inlets of the target charging pile are mainly responsible for allowing external airflow to enter the pile body of the charging pile, providing a source of fresh airflow for internal heat dissipation, etc. The several exhaust outlets of the target charging pile discharge the airflow after heat exchange from the charging pile to maintain the normal temperature and working environment inside the pile body of the target charging pile. It can be understood that the air inlet distributed on the air inlet door and the exhaust outlet distributed on the air outlet door can be rectangular grids, circular grids, or grids of other shapes.

[0041] See also Figure 3Considering that setting a hot fan or a powerful fan on the charging pile for heat dissipation will generate a lot of noise, this solution chooses to set a first ventilation duct near the air inlet inside the pile body of the charging pile, and the first ventilation duct is provided with air outlets, and the air outlets distributed on the first ventilation duct support the release of airflow toward the inside of the pile body of the target charging pile. On this basis, when the target charging pile needs to dissipate heat, the first airflow will be introduced into the first ventilation duct on the target charging pile by pressurizing.

[0042] See also Figure 3 , the pressurized first airflow will be transmitted in the first ventilation duct. When the air outlet of the first ventilation duct on the target charging pile releases the first airflow inside the pile body of the target charging pile, the first airflow will generate a larger movement speed near the air outlet, forming an airflow with a certain movement speed, and as the airflow movement speed continues to increase, according to the Bernoulli principle, the greater the fluid flow rate, the smaller the pressure. At this time, the air pressure at the air outlet of the first ventilation duct will gradually decrease, and a first pressure difference will be formed at the air inlet of the target charging pile on the side facing the outside of the pile body of the target charging pile and the side facing the inside of the pile body of the target charging pile according to the released first airflow and the second airflow of the external environment of the pile body of the target charging pile.

[0043] Exemplarily, the Bernoulli principle equation is as follows: ,in: is the fluid density; v is the fluid velocity; g is the gravitational acceleration; h is the height of the fluid; p is the pressure on the fluid, and constant is the fluid constant. According to the use scenario of the target charging pile, the height of the target charging pile remains unchanged, and the air density of the environment where the target charging pile is used remains unchanged, that is, the constant in the Bernoulli principle equation remains unchanged ( , g, h, constant). Therefore, the variables of the Bernoulli principle equation are the fluid velocity v and the pressure p on the fluid. The greater the fluid velocity v, the smaller the pressure on the fluid. According to the Bernoulli principle, the velocity of the first airflow released by the air outlet of the first ventilation duct inside the pile body of the target charging pile increases, and the pressure at the position of the air outlet of the first airflow released decreases, thereby generating a pressure difference.

[0044] For the above implementation, it is fully considered that although the fan can accelerate the flow of internal air, forming a relatively low-pressure area in front of the fan and a relatively high-pressure area behind the fan, thereby generating a pressure difference, this pressure difference is relatively small and may be sufficient to meet the heat dissipation requirements for small charging piles or situations where the heat dissipation demand is relatively small. However, when charging at high power, if you want the fan to generate a larger pressure difference, you need a larger wind speed, which will generate a larger noise problem. Therefore, by introducing a first ventilation duct and pressurizing the air flow into the first ventilation duct to accelerate the formation of the air flow, and then releasing the accelerated air flow through the air outlet of the first ventilation duct to reduce the pressure inside the pile body of the target charging pile near the air outlet, it is only necessary to introduce the pressurized air flow and spray it from the air outlet of the first duct to achieve a relatively large pressure difference on both sides of the air inlet of the target charging pile. By rationally utilizing the ventilation duct and the air flow pressure difference, it is possible to reduce the dependence on traditional large heat dissipation fans, reduce the noise during equipment operation, and improve the suitability of charging piles for use in densely populated areas.

[0045] As an optional but non-limiting implementation method, the first ventilation duct on the target charging pile is arranged in a ring-shaped manner on the side facing the inside of the pile body of the target charging pile near the air inlet of the target charging pile, and the first ventilation duct is provided with a plurality of air outlet holes smaller than a preset aperture, so that the first airflow introduced into the first ventilation duct can be ejected from the air outlet holes of the first ventilation duct into the inside of the pile body of the target charging pile, and the plurality of air outlet holes arranged on the first ventilation duct are evenly arranged according to preset intervals.

[0046] See also Figure 3 The first ventilation duct on the target charging pile can be a ventilation channel of a tubular structure with an inner diameter smaller than a preset inner diameter. The diameter of the air outlet arranged in the first ventilation duct on the target charging pile is smaller than the preset aperture. By adjusting the diameter of the air outlet arranged in the first ventilation duct, the speed of the air outlet of the first ventilation duct when releasing the first airflow can be controlled, so that the first airflow can be ejected from the air outlet of the first ventilation duct to the interior of the pile body of the target charging pile at a relatively high speed. For example, see Figure 4 , Figure 4 The dotted rectangular frame in the middle of the U-shaped character is the first ventilation duct installed on the target charging pile. The first ventilation duct has an air outlet hole with an inward aperture smaller than a preset aperture. The first airflow introduced into the first ventilation duct under pressure can be ejected through the air outlet hole of the first ventilation duct.

[0047] At the same time, by evenly arranging the multiple air outlets arranged on the first ventilation duct according to preset intervals, it is achieved that when the first airflow is ejected from the multiple air outlets arranged on the first ventilation duct, uniform pressure can be generated at each air outlet, thereby avoiding disordered airflow movement inside the pile body of the charging pile, wasting the pressure difference, and making it impossible to push the external airflow into the pile body of the charging pile.

[0048] As an optional but non-limiting implementation method, the first ventilation duct on the target charging pile is connected to the airflow conveying equipment, and the airflow conveying equipment can draw cold air from the underground cable duct as the first airflow and introduce it into the first ventilation duct on the target charging pile and / or the airflow conveying equipment can draw air from the inside of the pile body of the target charging pile that is already inside the pile body of the target charging pile as the first airflow and introduce it into the first ventilation duct on the target charging pile.

[0049] See also Figure 4 , the side door expansion diagram of the target charging pile, the exhaust fan located at the side door is cancelled, and an air flow conveying device is added to the bottom of the charging pile instead. The gas conveying device may refer to a device used to convey air from one location to another. The air flow conveying device can apply pressure to the air flow to make it flow, and may include different types of pumps, fans, compressors, etc. For example, the exhaust pump as an air flow conveying device promotes the flow of air by generating negative pressure or positive pressure, and the blower as an air flow conveying device pushes the air flow out by generating positive pressure, thereby realizing the conveying and discharge functions of the air flow.

[0050] See also Figure 4 , the first ventilation duct on the target charging pile is connected to the airflow conveying equipment, and the other end of the airflow conveying equipment can be connected to the underground cable duct. The airflow conveying equipment can use the underground cable duct to extract cold air as the first airflow, and then pressurize the first airflow and introduce it into the first ventilation duct, so that the air outlet of the first ventilation duct on the target charging pile releases the first airflow to generate a first pressure difference. In this way, the first airflow can not only generate a pressure difference to promote the movement of the airflow, but also because the first airflow comes from the cold air, when the first airflow enters the pile body of the target charging pile, it will generate heat exchange and absorb part of the heat for discharge.

[0051] See also Figure 3 and Figure 4 The airflow conveying device can also extract the airflow already inside the pile body of the target charging pile as the first airflow, and then pressurize the first airflow and introduce it into the first ventilation duct, so that the air outlet of the first ventilation duct on the target charging pile releases the first airflow to generate a first pressure difference. In this way, the first airflow from the pile body of the target charging pile can not only generate a pressure difference to promote the movement of the airflow, but also because the first airflow is the airflow from the pile body of the target charging pile, when the airflow conveying device is used to extract the airflow inside the pile body of the target charging pile, the airflow inside the pile body of the target charging pile will be driven to move, further reducing the pressure of the airflow inside the pile body of the target charging pile, so as to generate a larger pressure difference on the inside and outside of the air inlet.

[0052] As an optional but non-limiting implementation method, the airflow conveying equipment is configured in a reference space, the reference space is constructed with sound insulation materials and / or sound insulation structures, and the reference space can block the propagation of sound, or the reference space is an underground space surrounded by sound insulation barriers so that the propagation of sound in the space is weakened.

[0053] See also Figure 3 and Figure 4 , air flow conveying equipment such as exhaust pumps are installed in the reference space with sound insulation technology. Multi-layer sound insulation materials and special structural design effectively block the propagation of sound, creating a nearly silent operating environment for it. For example, specific sound insulation materials and structural design are used to avoid generating more noise, and air flow conveying equipment such as exhaust pumps do not need to operate at high power, so they do not generate too much heat. The reference space used by air flow conveying equipment such as exhaust pumps is located in the underground space, which can avoid setting up huge equipment on the ground, thereby saving more space for other purposes. Underground installation can make the layout of the ventilation system more reasonable. Air flow conveying equipment such as exhaust pumps can be integrated with other underground facilities, such as pipes and cables, reducing conflicts and interference between equipment.

[0054] S120. Based on the first pressure difference, drive the second airflow from the air inlet of the target charging pile into the pile body of the target charging pile to drive the third airflow to flow, where the third airflow includes the airflow inside the pile body of the target charging pile.

[0055] S130. Discharge heat generated inside the pile body of the target charging pile through a third airflow flowing inside the pile body of the target charging pile.

[0056] See also Figure 4 , the first pressure difference formed on the inner and outer sides of the air inlet of the target charging pile, the first pressure difference between the inside and outside of the pile body of the target charging pile makes the second airflow outside the pile body of the target charging pile have a tendency to flow inward, and the airflow in the higher pressure area will flow to the lower pressure area to achieve pressure balance. This pressure difference is like an invisible driving force, prompting the airflow to enter the internal space of the pile body of the target charging pile from the outside of the pile body of the target charging pile. The newly introduced second airflow interacts with the original third airflow inside the charging pile (especially the airflow near the air inlet of the target charging pile and flowing inside the pile body of the target charging pile) to generate airflow disturbance. This airflow disturbance can break the original third airflow balance state inside the pile body of the target charging pile, making the airflow inside the charging pile move more actively. Moreover, as the airflow accelerates, according to the Bernoulli principle, the greater the fluid flow rate, the smaller the pressure, so a pressure difference will be formed between different areas inside the charging pile, and this pressure difference can prompt the air to flow inside the charging pile, take away the heat generated inside the pile body of the target charging pile, and achieve the purpose of heat dissipation.

[0057] Optionally, the heat generated inside the pile body of the target charging pile is discharged through a third airflow flowing inside the pile body of the target charging pile, including: the heat generated inside the pile body of the target charging pile is discharged from the exhaust outlet of the target charging pile through the third airflow flowing inside the pile body of the target charging pile.

[0058] Optionally, the flow of the third airflow inside the target charging pile can be guided and accelerated by configuring an airflow guide device inside the target charging pile, including a guide plate, a grille, etc. For example, a curved air duct or an angled guide plate is provided inside the charging pile, so that the third airflow can change direction and speed during the flow process, thereby achieving acceleration.

[0059] As an optional but non-limiting implementation, based on the first pressure difference, driving the second airflow from the air inlet of the target charging pile into the pile body of the target charging pile to drive the third airflow to flow, including steps A1-A2:

[0060] Step A1. Generate a first reference driving force at the air inlet of the target charging pile based on the first pressure difference. The first reference driving force is a driving force that pushes the airflow from the first reference side of the air inlet of the target charging pile to the second reference side. The first reference side is a side facing the outside of the pile body of the target charging pile, and the second reference side is a side facing the inside of the pile body of the target charging pile.

[0061] Step A2: Based on the first reference driving force, an airflow channel is generated on both sides of the air inlet of the target charging pile, so that the second airflow is pressed from the air inlet of the target charging pile into the pile body of the target charging pile along the airflow channel to drive the third airflow to flow.

[0062] See also Figure 4 and Figure 5 When the first pressure difference is formed on the target charging pile, this first pressure difference will generate a specific force at the air inlet of the target charging pile, namely the first reference driving force. The first reference driving force is a driving force that pushes the second airflow from the first reference side facing the outside of the pile body of the target charging pile at the air inlet of the target charging pile to the second reference side facing the inside of the pile body of the target charging pile. The function of this first reference driving force is to guide the external second airflow into the inside of the pile body of the target charging pile, just like a "gravity", which attracts the second airflow outside the pile body of the target charging pile to the inside of the pile body of the target charging pile, providing power for the airflow inside the pile body.

[0063] See also Figure 4 and Figure 5Based on the first reference driving force, an airflow channel will be generated on both sides of the air inlet of the target charging pile. This airflow channel is formed by the airflow flow guided by the first reference driving force. When the first reference driving force acts on the airflow at the air inlet, it will cause the airflow to flow in a specific direction, thereby forming a relatively stable airflow channel on both sides of the air inlet. This airflow channel provides a path for the entry of the second airflow. The second airflow is pressed into the interior of the target charging pile from the air inlet of the target charging pile along the airflow channel, indicating that the second airflow enters the interior of the pile under a certain pressure.

[0064] See also Figure 4 and Figure 5 When the second airflow enters the pile body, it will drive the third airflow to flow. The third airflow includes the airflow inside the pile body of the target charging pile, which may be hot air generated by the heating components inside the charging pile or other airflows that are already flowing inside the pile body. The entry of the second airflow provides new power and direction for the third airflow, allowing the third airflow to flow more effectively. This flow can take away the heat inside the pile body and achieve heat dissipation for the charging pile. Exemplary, Figure 4 The middle blue part is the high-speed first airflow that is pressurized by the exhaust pump and ejected again after passing through the first ventilation duct. The green part is the natural wind from the external environment that blows into the pile body of the target charging pile from the air inlet of the target charging pile. The red part is the airflow containing heat that is blown out from the exhaust outlet of the target charging pile.

[0065] By adopting the above method, it is only necessary to pressurize and introduce air flow into the first ventilation duct to generate a first pressure difference, thereby generating a first reference driving force through the first pressure difference, and then generating an airflow channel at the air inlet of the target charging pile, so that the second airflow can be pressed into the interior of the pile body to drive the flow of the third airflow, which not only achieves the heat dissipation effect on the target charging pile, but also avoids the problem of loud noise caused by using fans and other equipment to blow air into the pile body to promote air flow movement.

[0066] According to the technical solution of the embodiment of the present invention, the air outlet of the first ventilation duct on the target charging pile can release airflow toward the interior of the pile body of the target charging pile. When the first airflow is pressurized and introduced into the first ventilation duct on the target charging pile, it will be further released into the interior of the pile body of the target charging pile through the air outlet of the first ventilation duct. Since the first airflow is a pressurized airflow, it will have a certain kinetic energy and pressure. When the first airflow is released toward the interior of the pile body, it will not only generate a higher airflow movement speed itself but also be able to quickly mix with the air inside the pile body, thereby increasing the airflow movement speed inside the pile body near the air inlet of the target charging pile. According to the idea that the greater the wind speed and the smaller the fluid pressure indicated by the Bernoulli fluid principle, the first airflow and the second airflow near the air inlet and located outside the pile body form a first pressure difference on the inside and outside of the air inlet. It is not difficult to see that since the pressure difference is generated after the first airflow is released, the problem of large noise caused by using a fan or other equipment to blow air into the interior of the pile body to promote airflow movement is avoided. A large pressure difference can be generated by releasing the pressurized airflow inside the pile body through the first ventilation duct. Furthermore, the second airflow is pressed into the interior of the pile body through the first pressure difference, and then the third airflow inside the pile body is driven to flow. During the flow of the third airflow inside the pile body, it can fully contact the heat-generating components and discharge the heat, thereby ensuring sufficient heat dissipation of the charging pile equipment and reducing equipment noise.

[0067] Figure 6 A flow chart of another method for heat dissipation treatment of a charging pile provided in an embodiment of the present invention. The technical solution of this embodiment further optimizes the process of releasing the first airflow to generate the first pressure difference through the air outlet of the first ventilation duct on the target charging pile in the aforementioned embodiment on the basis of the technical solution of the aforementioned embodiment. This embodiment can be combined with various optional solutions in one or more of the aforementioned embodiments.

[0068] like Figure 6 As shown, the heat dissipation processing method of the charging pile in the embodiment of the present invention may include the following process:

[0069] S510, determining a reference air intake volume required for heat dissipation inside the target charging pile, where the reference air intake volume is the airflow volume of the second airflow entering the target charging pile body from the air inlet of the target charging pile per unit time.

[0070] The air intake of a charging pile may refer to the amount of air entering the body of the charging pile from the air inlet of the charging pile per unit time, for example, the volume of air entering the interior of the charging pile per unit time. The size of the air intake is related to the heat dissipation effect, operation stability and service life of the charging pile. The charging pile will generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the temperature inside the charging pile will rise, affecting the performance and life of the electrical components, and may even cause safety accidents. The size of the air intake directly determines the heat dissipation effect of the charging pile. Sufficient air intake can ensure that the airflow can quickly take away the heat inside the charging pile and keep the charging pile running within a safe temperature range. For example, for a high-power fast-charging charging pile, due to its high output power and high heat generation, a larger air intake is required to ensure the heat dissipation effect. Otherwise, the charging pile may automatically reduce power or stop working due to excessive temperature.

[0071] S520. Determine first reference control information required for heat dissipation of the target charging pile based on the reference air intake volume. The first reference control information is used to control the airflow movement speed when the first airflow is released through the air outlet of the first ventilation duct on the target charging pile. The airflow movement speed required to be generated when the first airflow is released through the air outlet of the first ventilation duct on the target charging pile is positively correlated with the reference air intake volume.

[0072] See also Figure 4 and Figure 5 , the reference air intake volume is realized by driving the second airflow from the air inlet of the target charging pile into the pile body of the target charging pile according to the first pressure difference, and the first pressure difference is related to the air flow movement speed when the air outlet of the first ventilation duct on the target charging pile releases the first airflow. According to the Bernoulli fluid principle equation, when a large wind speed is generated at the air outlet of the first ventilation duct, the second airflow at the external environment of the first airflow ejection position and the air inlet of the target charging pile will produce a very large pressure difference, which can drive more second airflow into the pile body of the charging pile. It can be seen that if you want to achieve more air intake, you need to increase the air flow movement speed when the air outlet of the first ventilation duct releases the first airflow. Conversely, if you want to achieve less air intake, you need to reduce the air flow movement speed when the air outlet of the first ventilation duct releases the first airflow.

[0073] See also Figure 5The size of the first pressure difference is related to the air flow movement speed when the air outlet of the first ventilation duct on the target charging pile releases the first airflow. The size of the air flow movement speed when the air outlet of the first ventilation duct releases the first airflow is related to the pressure of the air flow pressurized and introduced into the first ventilation duct on the target charging pile and / or the aperture size of the air outlet of the first ventilation duct. Therefore, if you want to control the air flow movement speed when the air outlet of the first ventilation duct releases the first airflow, you can generate an airflow with a specific flow rate by controlling the pressure of the air flow pressurized and introduced into the first ventilation duct by the airflow conveying equipment, and the aperture size of the air outlet of the first ventilation duct.

[0074] See also Figure 5 , and then, the pressure difference pressure p formed on the inner and outer sides of the air inlet of the target charging pile can be controlled more accurately. This pressure forms a pressure difference with the environmental standard atmospheric pressure at a specific altitude where the charging pile is located, so that the second airflow can be pressed from the air inlet into the pile body of the charging pile to form an airflow duct, and then the second airflow pressed into the pile body of the target charging pile can be used to take away the heat generated inside the pile body of the target charging pile. According to the approximate equation for the relationship between wind pressure and wind speed (wp is wind pressure, v is wind speed): , where wp wind pressure = atmospheric pressure – air inlet pressure p. It is only necessary to adjust the wind pressure at the air inlet to control the flow velocity v of the first airflow entering the charging pile. The air intake per second can be calculated based on the wind speed and the area of ​​the air inlet, and the air intake can be accurately controlled based on the heat dissipation requirements.

[0075] S530: According to the first reference control information, a first airflow is released through an air outlet of a first ventilation duct on the target charging pile to generate a first pressure difference.

[0076] Among them, the air outlet of the first ventilation duct can release airflow toward the interior of the pile body of the target charging pile, the first airflow is the airflow that is pressurized and introduced into the first ventilation duct on the target charging pile, the first pressure difference is the pressure difference formed on the inner and outer sides of the air inlet of the target charging pile by the first airflow released by the air outlet of the first ventilation duct and the second airflow, the inner and outer sides of the air inlet are the side facing the outside of the pile body of the target charging pile at the air inlet of the target charging pile and the side facing the inside of the pile body of the target charging pile, and the second airflow is the natural wind close to the air inlet of the target charging pile and located outside the pile body of the target charging pile.

[0077] Optionally, according to the first reference control information, releasing the first airflow through the air outlet of the first ventilation duct on the target charging pile to generate the first pressure difference includes: introducing the first airflow into the first ventilation duct on the target charging pile according to the first reference control information, and releasing the first airflow through the air outlet of the first ventilation duct on the target charging pile to generate the airflow movement driving the second airflow to flow and generate the first pressure difference. The first reference control information is used to control and adjust the size of the air outlet of the first ventilation duct on the target charging pile and / or the introduction pressure when introducing the airflow into the first ventilation duct on the target charging pile.

[0078] As an optional but non-limiting implementation, according to the first reference control information, releasing the first airflow through the air outlet of the first ventilation duct on the target charging pile to generate the first pressure difference includes steps B1-B2:

[0079] Step B1, introducing a first airflow into a first ventilation duct on a target charging pile according to a first control parameter in the first reference control information, wherein the first control parameter is used to control and adjust an introduction pressure when introducing the airflow into the first ventilation duct on the target charging pile.

[0080] Step B2, according to the second control parameter in the first reference control information, the first airflow introduced into the first ventilation duct is released into the interior of the target charging pile through the air outlet of the first ventilation duct on the target charging pile, and forms a first pressure difference with the second airflow on the inner and outer sides of the air inlet of the target charging pile. The second control parameter is used to control and adjust the size of the air outlet of the first ventilation duct on the target charging pile.

[0081] See also Figure 4 and Figure 5 , air flow conveying equipment such as exhaust pumps play an important role in transmitting the extracted first air flow to the first ventilation duct at the air inlet of the target charging pile. There are small air outlet holes arranged on this first ventilation duct, as shown in the figure. Figure 4 and Figure 5 As shown in the dotted rectangular part on the middle air inlet door. Since the air outlet holes of the first ventilation duct are relatively small, the pressure generated when the air flow conveying equipment such as the exhaust pump is working will be converted into a larger air flow speed at several small air outlet holes in the first ventilation duct. Figure 4 and Figure 5 The blue arrow in the middle vividly demonstrates this phenomenon.

[0082] Alternatively, see Figure 4 and Figure 5 The aperture size of the air outlet of the first ventilation duct and the pressure support dynamic adjustment when the air flow conveying equipment such as the exhaust pump pressurizes and introduces the air flow into the first ventilation duct on the target charging pile means that the air flow movement speed v generated when the air outlet of the first ventilation duct releases the first air flow is in an adjustable and controllable state.

[0083] See also Figure 4 and Figure 5 According to the Bernoulli fluid principle equation, when the first ventilation duct generates a large airflow speed, a very large pressure difference will be formed between the natural wind near the air inlet of the target charging pile and outside the pile body of the target charging pile. This significant atmospheric pressure difference will cause the natural wind outside the pile body of the target charging pile to become a second airflow with a larger wind speed, and penetrate into the pile body of the target charging pile from the air inlet of the target charging pile. Subsequently, the second airflow will drive the third airflow to flow through the entire pile body, thereby forming an airflow channel. In this process, the heat generated by the target charging pile during operation can be taken out to achieve heat dissipation of the target charging pile.

[0084] By adopting the above method, by adjusting the pressure of the air inlet, the pressure difference with the atmospheric pressure can be effectively controlled, and then the air intake volume can be accurately adjusted. It is feasible to adjust a larger air intake volume according to the heat dissipation requirements of the equipment. In addition, the first ventilation duct on the target charging pile can be cleverly used to pressurize the airflow and release the first airflow to produce a pressure difference, and a small air volume can be used to leverage a large air volume, thereby achieving the purpose of rapid heat dissipation of the charging pile. In the past, the heat dissipation effect required several fans to work together to achieve, but now this solution can be achieved with an exhaust pump, so that the noise of the equipment and the economic cost of the equipment are greatly reduced.

[0085] S540: Based on the first pressure difference, drive the second airflow from the air inlet of the target charging pile into the pile body of the target charging pile to drive the third airflow to flow, where the third airflow includes the airflow inside the pile body of the target charging pile.

[0086] S550. The heat generated inside the pile body of the target charging pile is discharged through the third airflow flowing inside the pile body of the target charging pile.

[0087] As an optional but non-limiting implementation, the heat generated inside the pile body of the target charging pile is discharged through the third airflow flowing inside the pile body of the target charging pile, including the following steps C1-C2:

[0088] Step C1, releasing the fourth airflow through the air outlet of the second ventilation duct on the target charging pile to generate a second pressure differential, the air outlet of the second ventilation duct can release the airflow toward the outside of the pile body of the target charging pile close to the exhaust outlet of the target charging pile, the fourth airflow is the airflow that is pressurized and introduced into the second ventilation duct on the target charging pile, the second pressure differential is the pressure difference formed on the inner and outer sides of the exhaust outlet of the target charging pile according to the third airflow and the fourth airflow released through the air outlet of the second ventilation duct, the inner and outer sides of the exhaust outlet are the side facing the outside of the pile body of the target charging pile and the side facing the inside of the pile body of the target charging pile at the exhaust outlet of the target charging pile.

[0089] Step C2: based on the second pressure difference, drive the third airflow to be pressed out from the exhaust outlet of the target charging pile to the outside of the pile body of the target charging pile, so as to discharge the heat generated inside the pile body of the target charging pile.

[0090] See also Figure 5 Considering that if the exhaust outlet of the charging pile is not smooth, the heat cannot be quickly discharged from the pile body of the charging pile. Therefore, this solution chooses to set a second ventilation duct near the exhaust outlet inside the pile body of the charging pile, and the second ventilation duct is provided with air outlets. The air outlets distributed on the second ventilation duct support the release of airflow toward the outside of the pile body of the target charging pile near the exhaust outlet of the target charging pile. On this basis, when the target charging pile needs to dissipate heat, the fourth airflow will be introduced into the second ventilation duct on the target charging pile by pressurizing.

[0091] See also Figure 3 and Figure 5 , the pressurized fourth airflow will be transmitted in the second ventilation duct. When the air outlet of the second ventilation duct on the target charging pile releases the fourth airflow outside the pile body of the target charging pile, the fourth airflow will generate a larger movement speed near the air outlet, forming an airflow with a certain movement speed. At this time, the air pressure at the air outlet of the second ventilation duct will gradually decrease, and the second pressure difference will be formed on both sides of the exhaust outlet of the target charging pile according to the air pressure of the released fourth airflow and the air pressure of the third airflow near the exhaust outlet of the target charging pile and located in the internal environment of the pile body of the target charging pile, thereby accelerating the third airflow to carry heat for rapid discharge under the impetus of the second pressure difference.

[0092] As an optional but non-limiting implementation, see Figure 5The second ventilation duct on the target charging pile is arranged in a ring-shaped manner on the side of the target charging pile facing the outside of the pile body of the target charging pile near the exhaust outlet of the target charging pile. The second ventilation duct is arranged with a plurality of air outlet holes smaller than a preset aperture, so that the fourth airflow introduced into the second ventilation duct can be ejected from the air outlet holes of the second ventilation duct to the outside of the pile body of the target charging pile. The plurality of air outlet holes arranged on the second ventilation duct are evenly arranged according to preset intervals.

[0093] As an optional but non-limiting implementation, see Figure 5 The second ventilation duct on the target charging pile is connected to the airflow conveying device, and the airflow conveying device can draw cold air from the underground cable duct as the fourth airflow and introduce it into the second ventilation duct on the target charging pile and / or the airflow conveying device can draw air that is already inside the pile body of the target charging pile from the inside of the pile body of the target charging pile as the fourth airflow and introduce it into the second ventilation duct on the target charging pile.

[0094] It should be noted that the airflow delivery channel connected to the first ventilation duct on the target charging pile and the airflow delivery channel connected to the second ventilation duct on the target charging pile can be the same airflow delivery channel or different airflow delivery channels.

[0095] As an optional but non-limiting implementation, see Figure 5 , releasing the fourth airflow through the air outlet of the second ventilation duct on the target charging pile to generate a second pressure difference, including the following steps:

[0096] Determine the reference air output volume required for heat dissipation inside the pile body of the target charging pile, the reference air output volume is the air flow rate of the third airflow that discharges the air flow inside the charging pile from the exhaust outlet of the target charging pile to the outside of the pile body of the target charging pile per unit time; determine the second reference control information required for heat dissipation of the target charging pile according to the reference air output volume, the second reference control information is used to control the air flow movement speed when the fourth airflow is released through the air outlet of the second ventilation duct on the target charging pile, and the air flow movement speed required to be generated when the air outlet of the second ventilation duct on the target charging pile releases the fourth airflow is positively correlated with the reference air output volume; according to the second reference control information, the fourth airflow is released through the air outlet of the second ventilation duct on the target charging pile to generate a second pressure difference.

[0097] As an optional but non-limiting implementation, see Figure 5 , releasing a fourth airflow through an air outlet of a second ventilation duct on a target charging pile to generate a second pressure difference according to the second reference control information, comprising the following steps:

[0098] In accordance with the third control parameter in the second reference control information, the fourth airflow is introduced into the second ventilation duct on the target charging pile, and the third control parameter is used to control and adjust the introduction pressure when the airflow is introduced into the second ventilation duct on the target charging pile; in accordance with the fourth control parameter in the second reference control information, the fourth airflow introduced into the second ventilation duct is released to the outside of the pile body of the target charging pile through the air outlet of the second ventilation duct on the target charging pile, and a second pressure difference is formed between the fourth airflow and the third airflow on the inner and outer sides of the exhaust outlet of the target charging pile, and the fourth control parameter is used to control the size of the air outlet of the second ventilation duct on the target charging pile.

[0099] As an optional but non-limiting implementation, see Figure 5 Based on the second pressure difference, driving the third airflow to be pressed out from the exhaust outlet of the target charging pile to the outside of the pile body of the target charging pile includes the following steps:

[0100] A second reference driving force is generated at the exhaust outlet of the target charging pile based on the second pressure difference, and the second reference driving force is a driving force that pushes the airflow from the third reference side of the exhaust outlet of the target charging pile to the fourth reference side, the third reference side being the side of the exhaust outlet of the target charging pile facing the inside of the pile body of the target charging pile, and the fourth reference side being the side of the exhaust outlet of the target charging pile facing the outside of the pile body of the target charging pile; furthermore, an airflow channel can be generated on the inner and outer sides of the exhaust outlet of the target charging pile based on the second reference driving force, so that the third airflow is pressed out from the exhaust outlet of the target charging pile along the airflow channel to the outside of the pile body of the target charging pile, so as to discharge the heat generated inside the pile body of the target charging pile.

[0101] Understandably, see Figure 5 A second ventilation duct is set at the exhaust outlet of the target charging pile, and the fourth airflow is released through the air outlet of the second ventilation duct on the target charging pile to generate a second pressure difference, thereby driving the third airflow to be pressed out from the exhaust outlet of the target charging pile to the outside of the pile body of the target charging pile for heat dissipation based on the second pressure difference. The specific details are the same as those of the first ventilation duct and will not be repeated here.

[0102] According to the technical solution of the embodiment of the present invention, the air outlet of the first ventilation duct on the target charging pile can release airflow toward the interior of the pile body of the target charging pile. When the first airflow is pressurized and introduced into the first ventilation duct on the target charging pile, it will be further released into the interior of the pile body of the target charging pile through the air outlet of the first ventilation duct. Since the first airflow is a pressurized airflow, it will have a certain kinetic energy and pressure. When the first airflow is released toward the interior of the pile body, it will not only generate a higher airflow movement speed itself but also be able to quickly mix with the air inside the pile body, thereby increasing the airflow movement speed inside the pile body near the air inlet of the target charging pile. According to the idea that the greater the wind speed and the smaller the fluid pressure indicated by the Bernoulli fluid principle, the first airflow and the second airflow near the air inlet and located outside the pile body form a first pressure difference on the inside and outside of the air inlet. It is not difficult to see that since the pressure difference is generated after the first airflow is released, the problem of large noise caused by using a fan or other equipment to blow air into the interior of the pile body to promote airflow movement is avoided. A large pressure difference can be generated by releasing the pressurized airflow inside the pile body through the first ventilation duct. Furthermore, the second airflow is pressed into the interior of the pile body through the first pressure difference, and then the third airflow including the airflow inside the pile body is driven to flow. During the flow of the third airflow inside the pile body, it can fully contact the heat-generating components and discharge the heat, thereby ensuring sufficient heat dissipation of the charging pile equipment and reducing equipment noise.

The technical solution of the embodiment of the present invention is applicable to the situation of dissipating heat from a charging pile. The charging pile heat dissipation processing device can be implemented in the form of software and / or hardware, and is generally integrated in any electronic device with network communication function, which can be a mobile terminal, PC or server, etc.

[0104] like Figure 7 As shown, the heat dissipation treatment device of the charging pile according to the embodiment of the present invention may include the following:

[0105] The first processing module 610 is used to release a first airflow through an air outlet of a first ventilation duct on a target charging pile to generate a first pressure difference. The air outlet of the first ventilation duct can release airflow toward the inside of a pile body of the target charging pile. The first airflow is an airflow that is pressurized and introduced into the first ventilation duct on the target charging pile. The first pressure difference is a pressure difference formed on the inner and outer sides of an air inlet of the target charging pile by the first airflow released through the air outlet of the first ventilation duct and the second airflow.

The second control parameter is used to control and adjust the size of the air outlet of the first ventilation duct on the target charging pile.

[0115] On the basis of the above embodiment, optionally, the first ventilation duct on the target charging pile is arranged in a ring-shaped manner on the side facing the inside of the pile body of the target charging pile near the air inlet of the target charging pile, and the first ventilation duct is provided with a plurality of air outlet holes smaller than a preset aperture, so that the first airflow introduced into the first ventilation duct can be ejected from the air outlet holes of the first ventilation duct into the inside of the pile body of the target charging pile, and the plurality of air outlet holes arranged on the first ventilation duct are evenly arranged according to preset intervals.

[0118] On the basis of the above embodiment, optionally, based on the first pressure difference, driving the second airflow from the air inlet of the target charging pile into the pile body of the target charging pile to drive the third airflow to flow, including:

[0119] A first reference driving force is generated at the air inlet of the target charging pile based on the first pressure difference, wherein the first reference driving force is a driving force that drives the airflow from a first reference side of the air inlet of the target charging pile to a second reference side, wherein the first reference side is a side facing the outside of the pile body of the target charging pile, and the second reference side is a side facing the inside of the pile body of the target charging pile;

[0121] Based on the above embodiment, optionally, discharging heat generated inside the pile body of the target charging pile through a third airflow flowing inside the pile body of the target charging pile includes:

[0122] The second pressure differential is generated by releasing the fourth airflow through the air outlet of the second ventilation duct on the target charging pile, and the air outlet of the second ventilation duct can release the airflow toward the outside of the pile body of the target charging pile close to the exhaust outlet of the target charging pile. The fourth airflow is the airflow that is pressurized and introduced into the second ventilation duct on the target charging pile. The second pressure differential is the pressure difference formed on the inner and outer sides of the exhaust outlet of the target charging pile according to the third airflow and the fourth airflow released by the air outlet of the second ventilation duct.

[0124] According to the technical solution of the embodiment of the present invention, the air outlet of the first ventilation duct on the target charging pile can release airflow toward the interior of the pile body of the target charging pile. When the first airflow is pressurized and introduced into the first ventilation duct on the target charging pile, it will be further released into the interior of the pile body of the target charging pile through the air outlet of the first ventilation duct.
