[0002] With the rapid expansion of the electric vehicle market, the requirements for charging speed of charging piles are constantly increasing. The charging power of charging piles has gradually increased from the initial 20KW to the current 1000KW supercharging level. The substantial increase in charging power causes the internal power module of the charging pile to generate a lot of heat during operation. In order to ensure the stable operation of the charging pile and avoid damage to the equipment or affect the charging efficiency due to overheating, it is generally adopted to increase the number of fans and increase the size of the fans for heat dissipation. However, with the increase and size of the fans, serious noise problems have been brought about. Charging pile equipment is usually installed in densely populated areas, such as residential areas. When measured at close range, the noise generally exceeds 100 decibels. Such high-intensity noise has a great negative impact on the surrounding environment and personnel, and cannot meet the requirements of densely populated areas for a low-noise environment.

[0017] The technical solution of the embodiment of the present invention is to emit a first sound wave from an air medium toward a first reflecting surface, where the first sound wave is a noise sound wave emitted by performing a heat dissipation treatment operation on a target charging pile, and the first reflecting surface is a concave reflecting surface; the first sound wave is reflected by the first reflecting surface to generate a second sound wave, and the second sound wave is emitted from the air medium toward the second reflecting surface, where the second reflecting surface can make the reflected wave generated when the sound wave is vertically incident on the reflecting surface return in the opposite direction to the incident wave, thereby realizing the use of the concave reflecting surface to reflect the noise sound waves emitted in all directions by the charging pile during heat dissipation, so that the divergent noise sound waves can be returned in parallel ; The second sound wave is reflected by the second reflection surface to generate a third sound wave, and the third sound wave and the fifth sound wave are at least partially offset.

[0035] Embodiment 1

[0036] Figure 1 A flow chart of a charging pile noise reduction processing method provided in Embodiment 1 of the present invention. The technical solution of the embodiment of the present invention is applicable to the case of reducing the noise sound waves generated when the charging pile is dissipated. The method can be performed by a charging pile noise reduction processing device. The charging pile noise reduction processing device can be implemented in the form of software and / or hardware, and can be integrated in any electronic device with network communication function, which can be a mobile terminal, PC or server, etc.

[0037] like Figure 1 As shown, the charging pile noise reduction processing method of the first embodiment of the present invention may include the following process:

[0038] S101. Emit a first sound wave from an air medium toward a first reflecting surface, where the first sound wave is a noise sound wave emitted by performing a heat dissipation operation on a target charging pile, and the first reflecting surface is a concave reflecting surface.

[0039] In an embodiment of the present invention, 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 power into a current and voltage suitable for charging the battery of an electric vehicle by connecting to the power grid, and is connected to the electric vehicle through a 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 electrical energy to the electric vehicle in a relatively short time, while the slow charging mode charges at a lower power, has less impact on the life of the battery, and is suitable for charging when parked for a long time. The target charging pile can be a charging pile with heat dissipation requirements.

[0040] As the charging power of the charging pile increases, the internal power module of the charging pile will generate a lot of heat during operation. Therefore, in order to ensure the stable operation of the charging pile, the charging pile needs to be cooled. However, in the process of cooling the charging pile, the cooling components used will generate very loud noise waves, affecting the surrounding environment or residents. The cooling component refers to a device that can cool the target charging pile, such as a fan, exhaust pump, etc. For example, Figure 2 As shown, the charging pile uses a heat dissipation component such as a fan as an example. During operation, the heat dissipation component will generate an airflow pressure difference near the heat dissipation component, so that the gas flow inside the charging pile forms an airflow, thereby sucking in cold air from the outside to take away the heat generated by the charging pile during operation and discharging the hot air to the outside. At the same time, the heat dissipation component will also emit corresponding noise sound waves during operation.

[0041] Specifically, when the target charging pile is subjected to heat dissipation operation, the noise sound wave emitted by the heat dissipation component is used as the first sound wave, and the first sound wave is emitted from the air medium toward the first reflecting surface, wherein the first reflecting surface is a concave reflecting surface.

[0042] S102, generating a second sound wave by reflecting the first sound wave through the first reflection surface, and emitting the second sound wave from the air medium toward the second reflection surface, wherein the second reflection surface enables the reflected wave generated when the sound wave is vertically incident on the reflection surface to return in a direction opposite to the incident wave.

[0043] Specifically, the sound wave after the first sound wave is reflected by the first reflection surface is used as the second sound wave, and the second sound wave can be emitted from the air medium toward the second reflection surface. The second reflection surface can be a metal shell of the target charging pile, so that the inclination angle of the first reflection surface can be adjusted according to the shape of the target charging pile shell, so that the second sound wave can be vertically incident on the second reflection surface, thereby better adapting to charging piles of different shapes.

[0044] For example, Figure 3 As shown, Figure 3 The middle dotted line ① represents the noise sound wave emitted when the target charging pile is subjected to heat dissipation treatment, that is, the first sound wave. This noise sound wave can be regarded as a part of the spherical wave and has divergence. Figure 3 The rightmost curved surface area represents the first reflection surface. Figure 3 The middle dotted line ② represents the second sound wave after the first sound wave is reflected by the first reflection surface. Figure 3The leftmost solid line in the figure represents the second reflection surface. Furthermore, according to the law of reflection, that is, the reflection angle is equal to the incident angle, when the first sound wave is incident on the first reflection surface, since the first reflection surface is a concave reflection surface, the normal directions of each point on the first reflection surface are different, the incident angles of the first sound wave at each point on the first reflection surface are different, and the corresponding reflection angles are also different. Therefore, the propagation direction of the second sound wave can be controlled by adjusting the curvature of the first reflection surface, so that the second sound wave generated after the divergent first sound wave is reflected by the first reflection surface can be returned horizontally.

[0045] Similarly, according to the law of reflection, when the sound wave is incident on the reflecting surface vertically, that is, the incident angle is 0, the reflected wave will return in the opposite direction of the incident wave; when the sound wave is incident on the reflecting surface obliquely, that is, the incident angle is not 0, the reflected wave will be reflected on the other side of the normal of the reflecting surface along the same incident angle direction. Therefore, the second reflecting surface can return the reflected wave generated by the second sound wave incident vertically in the opposite direction of the second sound wave.

[0046] S103, generating a third sound wave by reflecting the second sound wave through the second reflecting surface, and at least partially canceling the third sound wave with the fifth sound wave, the fifth sound wave is generated by reflecting the fourth sound wave through the first reflecting surface, and the fourth sound wave is a noise sound wave that is generated by performing a heat dissipation operation on the target charging pile after emitting the first sound wave and is incident from the air medium toward the first reflecting surface.

[0047] In the embodiment of the present invention, the process of at least partially canceling out the third sound wave and the fifth sound wave can be realized according to the half-wave loss principle of sound wave reflection, that is, when the sound wave is vertically incident from a medium with small wave impedance to a medium with large wave impedance, it is reflected from the interface back to the medium with small wave impedance, and a π phase mutation will occur between the reflected wave and the incident wave, and the π phase mutation corresponds to half a wavelength. Figure 4 As shown, the dotted line represents the third sound wave that returns from the metal medium after the second sound wave is vertically incident from the air medium to the metal medium. The third sound wave undergoes a π phase mutation relative to the subsequent fifth sound wave represented by the solid line along the same propagation direction and path as the second sound wave. At this time, the crest of the third sound wave corresponds to the trough of the fifth sound wave, and the trough of the third sound wave corresponds to the crest of the fifth sound wave. The third sound wave and the fifth sound wave can be superimposed on each other to reduce the amplitude of the third sound wave and the fifth sound wave, thereby achieving noise reduction processing of the sound wave. Therefore, when the wave impedance of the second reflection surface is greater than the wave impedance of the air, the third sound wave and the fifth sound wave will at least partially cancel each other out based on the half-wave loss principle.

[0048] Specifically, when the target charging pile is subjected to a heat dissipation operation, the noise sound wave continuously emitted by the heat dissipation component after emitting the first sound wave can be used as the fourth sound wave. The fourth sound wave has the same propagation direction and path as the first sound wave, and is emitted from the air medium toward the first reflecting surface. The sound wave after the fourth sound wave is reflected by the first reflecting surface can be used as the fifth sound wave. The fifth sound wave also has the same propagation direction and path as the second sound wave, and is emitted from the air medium toward the second reflecting surface. Furthermore, the sound wave after the second sound wave is reflected by the second reflecting surface is used as the third sound wave, and the wave impedance of the second reflecting surface is set to be greater than the wave impedance of the air. Then, the third sound wave will propagate in opposite directions with the fifth sound wave and perform at least partial sound wave cancellation based on the half-wave loss principle. Repeating the above sound wave cancellation process can achieve noise reduction processing of the noise sound waves emitted when the target charging pile is subjected to a heat dissipation operation.

[0049] For example, Figure 3 As shown, Figure 3 The middle dotted line ④ represents the noise sound wave that is continuously emitted after the first sound wave is emitted when the target charging pile is subjected to heat dissipation treatment, i.e., the fourth sound wave. Figure 3 The middle dotted line ⑤ represents the fifth sound wave after the fourth sound wave is reflected by the first reflection surface. Figure 3 The middle dotted line ③ represents the third sound wave after the second sound wave is reflected by the second reflection surface. Figure 3 The third sound wave and the fifth sound wave propagate in opposite directions and cancel each other out at least partially.

[0050] As an optional but non-limiting implementation method, the second sound wave generated by the first reflection surface reflecting the first sound wave can be vertically incident on the second reflection surface, the third sound wave generated by the second reflection surface reflecting the second sound wave can be returned in the opposite direction of the incident wave, and the fifth sound wave can be vertically incident on the second reflection surface.

[0051] Specifically, if the second reflection surface can receive the second sound wave incident vertically, the third sound wave reflected by the second reflection surface will return in the opposite direction of the second sound wave. At the same time, the fifth sound wave has the same propagation direction as the second sound wave and can also be incident vertically on the second reflection surface. Furthermore, the propagation direction of the third sound wave reflected by the second reflection surface is opposite to the propagation direction of the fifth sound wave, so that the third sound wave and the fifth sound wave can better cancel each other out.

[0052] The technical solution of the embodiment of the present invention is to emit a first sound wave from an air medium toward a first reflecting surface, where the first sound wave is a noise sound wave emitted by performing a heat dissipation treatment operation on a target charging pile, and the first reflecting surface is a concave reflecting surface; the first sound wave is reflected by the first reflecting surface to generate a second sound wave, and the second sound wave is emitted from the air medium toward the second reflecting surface, where the second reflecting surface can make the reflected wave generated when the sound wave is vertically incident on the reflecting surface return in the opposite direction to the incident wave, thereby realizing the use of the concave reflecting surface to reflect the noise sound waves emitted in all directions by the charging pile during heat dissipation, so that the divergent noise sound waves can be returned in parallel ; The second sound wave is reflected by the second reflection surface to generate a third sound wave, and the third sound wave and the fifth sound wave are at least partially offset. The fifth sound wave is generated by the first reflection surface reflecting the fourth sound wave. The fourth sound wave is a noise sound wave incident from the air medium toward the first reflection surface after the first sound wave is emitted by performing a heat dissipation operation on the target charging pile. The third sound wave reflected by the second reflection surface undergoes a π phase mutation relative to the fifth sound wave reflected by the first reflection surface, and then the third sound wave and the fifth sound wave can at least partially offset each other, thereby achieving noise reduction processing of the noise sound wave. At the same time, there is no need to add additional noise reduction equipment in the process of noise reduction processing of the noise sound wave of the charging pile. The structure is simple and reliable, the cost is low, and the charging piles of different shapes can be adapted by adjusting the inclination angle of the first reflection surface, which will not affect the heat dissipation process of the charging pile.

[0053] Embodiment 2

[0054] Figure 5 A flow chart of a charging pile noise reduction processing method provided in Embodiment 2 of the present invention. The technical solution of this embodiment further optimizes the process of emitting the first sound wave from the air medium toward the first reflecting surface 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.

[0055] like Figure 5 As shown, the charging pile noise reduction processing method of the second embodiment of the present invention may include the following process:

[0056] S201. The first sound wave generated when the heat dissipation operation is performed on the target charging pile is emitted from a reference position area in the air medium. The reference position area is a preset spatial area range centered on a reference position point in the air medium. The reference position point is the focal position of the concave reflective surface corresponding to the first reflective surface.

[0057] Specifically, when the target charging pile is subjected to heat dissipation treatment, the noise sound wave emitted by the heat dissipation component is used as the first sound wave, and the first sound wave is emitted from the reference position area in the air medium. The reference position area is a preset spatial area range centered on the focal position of the concave reflecting surface corresponding to the first reflecting surface, and the smaller the reference position area, the greater the probability that the first sound wave is emitted from the focal position of the concave reflecting surface, and the better the sound wave parallel effect after the first sound wave is reflected by the first reflecting surface. For example, the reference position area can be a spherical area range with a radius of 5 cm centered on the focal position of the concave reflecting surface corresponding to the first reflecting surface.

[0058] As an optional but non-limiting implementation, the first sound wave generated when the heat dissipation operation is performed on the target charging pile is emitted from the reference position area in the air medium, including the following steps A1-A3:

[0059] Step A1: Drive the gas inside the target charging pile to flow by at least two heat dissipation components configured on the target charging pile to form airflows corresponding to each heat dissipation component, so as to discharge the heat generated inside the target charging pile. The target charging pile is associated with a first reflection surface, and the first reflection surface is shared by at least two heat dissipation components.

[0060] Step A2: When at least two heat dissipation components drive the gas inside the target charging pile to flow, the noise sound waves emitted by each heat dissipation component are superimposed through the sound wave guiding component. The sound wave guiding component is used to change the propagation path and characteristics of the sound waves to converge and superimpose the noise sound waves generated by each heat dissipation component.

[0061] Step A3: emitting the first sound wave generated by sound wave superposition through the sound wave guiding component from the reference position area in the air medium.

[0062] In an embodiment of the present invention, each heat dissipation component will generate noise sound waves accordingly during operation. Therefore, a sound wave guiding component can be used to converge and superimpose the noise sound waves generated by each heat dissipation component. Among them, the process of convergence and superposition of noise sound waves can be realized based on the principle of sound wave interference and constructive interference or the principle of waveguide and resonance cavity. The principle of sound wave interference means that when multiple sound waves meet the preset phase and amplitude conditions, sound wave superposition can be achieved. At the same time, if multiple sound waves are in phase, that is, the phase difference is 0 or an integer multiple of 2π, constructive interference will occur. Exemplarily, the sound wave guiding component can adjust the frequency and phase of the emitted noise sound waves by controlling the rotation speed of at least two heat dissipation components, so that at least two noise sound waves meet the preset phase and amplitude conditions, so that at least two noise sound waves can be converged and superimposed based on the principle of sound wave interference and constructive interference.

[0063] The principle of waveguide and resonance cavity refers to the use of waveguide and resonance cavity to change the propagation path and characteristics of sound waves. Among them, waveguide refers to a structure that can guide sound waves to propagate along a specific direction, and resonance cavity refers to a structure that can enhance sound waves at a specific frequency. Exemplarily, the sound wave guiding component can be composed of a waveguide and a resonance cavity. The waveguide can be made of a material with acoustic properties in the form of a pipe and connected to the air outlets of at least two heat dissipation components. The size and shape of the resonance cavity can be set based on the resonant frequency of the resonance cavity and the main frequency of the noise sound wave. Furthermore, the sound wave guiding component can guide the noise sound waves of each heat dissipation component to converge into the resonance cavity through the waveguide. At the same time, the sound wave guiding component can superimpose the noise sound waves of each heat dissipation component that converge through the resonance cavity.

[0064] Specifically, the sound wave guiding component can be used to converge and superimpose the noise sound waves generated by at least two heat dissipation components when dissipating heat to the target charging pile. Among them, the target charging pile is associated with only one first reflection surface, and at least two heat dissipation components configured for the target charging pile share the first reflection surface, and the corresponding target charging pile is also associated with only one reference position area. Furthermore, the noise sound waves converged and superimposed by the sound wave guiding component can be used as the first sound wave and emitted from the reference position area in the air medium, so that the target charging pile only needs to pass through a first reflection surface to achieve noise reduction processing of the noise sound waves, which is simple in structure and reduces the subsequent maintenance cost of the first reflection surface.

[0065] As an optional but non-limiting implementation, the first sound wave generated when the heat dissipation operation is performed on the target charging pile is emitted from the reference position area in the air medium, including the following steps B1-B2:

[0066] Step B1: for each heat dissipation component of at least one heat dissipation component configured on the target charging pile, drive the gas inside the target charging pile to flow through each heat dissipation component to form an airflow corresponding to each heat dissipation component, the target charging pile is associated with at least two first reflection surfaces, and each heat dissipation component of at least one heat dissipation component corresponds to a first reflection surface.

[0067] Step B2: The noise sound waves emitted by each heat dissipation component when each heat dissipation component drives the gas inside the target charging pile to flow are used as the first sound waves, and are emitted from the reference position area in the air medium.

[0068] Specifically, at least one heat dissipation component configured in the target charging pile can correspond to a first reflection surface, and each corresponding first reflection surface can also correspond to a reference position area. Furthermore, when at least one heat dissipation component configured in the target charging pile dissipates heat for the target charging pile, the noise sound waves generated by each heat dissipation component can be used as first sound waves and emitted in the corresponding reference position areas, so that there is no need to set up additional sound wave guiding components, which reduces economic costs, and the heat dissipation component is closer to the first reflection surface, so that the noise sound wave has a better noise reduction effect.

[0069] For example, Figure 6 As shown in the figure, the yellow circular area on the left side is the reference position area corresponding to each heat dissipation component, the black dotted line is the first sound wave corresponding to each heat dissipation component, and the dark blue curved area on the right side is the first reflection surface corresponding to each heat dissipation component. Therefore, the first sound wave generated by each heat dissipation component can be emitted from the corresponding reference area toward the corresponding first reflection surface to enhance the noise reduction effect on noise waves.

[0070] As an optional but non-limiting implementation method, the heat dissipation component is used to apply pressure to the gas to make the gas flow to form an airflow. Each heat dissipation component is associated with a corresponding ventilation duct. When performing a heat dissipation operation, each heat dissipation component can input cold air to the heat dissipation component through the ventilation duct or output hot air carrying the internal heat of the target charging pile.

[0071] Specifically, each heat dissipation component can be associated with a ventilation duct, so that the heat dissipation component can inhale cold air through the corresponding ventilation duct to dissipate heat from the target charging pile, or the heat dissipation component can discharge the hot air after dissipating heat from the target charging pile through the corresponding ventilation duct. At the same time, the ventilation duct associated with the heat dissipation component can be connected to the underground cable duct, so that the heat dissipation component can extract cold air from the underground cable duct to dissipate heat from the target charging pile, avoiding the heat dissipation component from being unable to inhale cold air from the outside when the outside weather is hot, thereby improving the heat dissipation efficiency of the charging pile. At the same time, the connection between the ventilation duct and the underground cable duct can make the layout of the ventilation system more reasonable and reduce conflicts and interference between equipment.

[0072] S202, propagating a first sound wave emitted from a reference position area in an air medium toward a first reflection surface.

[0073] Specifically, the first sound wave can be propagated from the reference position area in the air medium toward the first reflection surface to enhance the parallel effect of the sound wave after the first sound wave is reflected by the first reflection surface, thereby better realizing noise reduction processing of the sound wave.

[0074] As an optional but non-limiting implementation, propagating a first sound wave emitted from a reference position region in an air medium toward a first reflection surface includes:

[0075] The first sound wave emitted from the reference position area in the air medium is propagated toward the first reflecting surface arranged in the reference sound-absorbing chamber. The reference sound-absorbing chamber has a closed or semi-closed spatial structure and the reference sound-absorbing chamber can limit the propagation range of the first sound wave so that the first sound wave can reflect the sound wave and absorb the sound wave energy multiple times inside the closed or semi-closed spatial structure.

[0076] In an embodiment of the present invention, the target charging pile may be configured with a reference silencing chamber, and the first reflecting surface may be configured in the reference silencing chamber, wherein the reference silencing chamber is a space structure with closed or semi-closed characteristics, and the interior of the reference silencing chamber is hollow, that is, the propagation medium is air, and the chamber wall of the reference silencing chamber may be a metal medium. Furthermore, when the first sound wave propagates toward the first reflecting surface configured in the reference silencing chamber, due to the difference in wave impedance between the chamber wall and the medium in the chamber, most of the sound waves propagating to the chamber wall will be reflected back by the chamber wall. At the same time, after the sound waves in the reference silencing chamber are reflected multiple times by the chamber wall, multiple reflected waves will be generated, and different sound waves in the reference silencing chamber will interfere with each other and absorb energy from each other. For example, when the phases of different sound waves in the reference silencing chamber meet certain conditions, destructive interference will occur, resulting in the peaks and troughs of different sound waves in the reference silencing chamber canceling each other out, thereby reducing the intensity of the noise sound waves.

[0077] The reference anechoic chamber can also be regarded as a resonance chamber. When the frequency of the sound waves in the reference anechoic chamber is close to or equal to the natural frequency of the reference anechoic chamber, a resonance phenomenon will be triggered, causing the air molecules in the reference anechoic chamber to vibrate violently and interact with the vibration of the sound waves in the reference anechoic chamber, consuming the energy of the sound waves in the reference anechoic chamber. At the same time, the walls of the reference anechoic chamber can also be made of sound insulation materials, such as mineral wool, glass wool, polyester fiber sound-absorbing panels, and sound insulation felt, etc., to directly absorb the energy of the sound waves propagating to the walls. A sound insulation layer can also be added to the walls of the reference anechoic chamber to further enhance the noise reduction capability of the sound waves in the reference anechoic chamber.

[0079] In an embodiment of the present invention, the wall of the reference silencing chamber may be pre-configured with at least one vent so that the heat dissipation component configured for the target charging pile can inhale cold air from the outside through the vent when dissipating heat from the target charging pile or discharge hot air after dissipating heat from the target charging pile. Figure 7 and Figure 8 As shown in FIG. 1 , a vent is provided under the wall of the reference silencing chamber, and the target charging pile is provided with multiple heat dissipation components. Figure 7 In the example, the heat dissipation component draws in cold air from the outside through the vents configured under the reference muffler, and generates an airflow from right to left to take away the heat generated by the target charging pile during operation, thereby achieving heat dissipation of the target charging pile body. Figure 8 In the figure, the heat dissipation component generates an airflow from left to right, and discharges the hot air after the target charging pile body dissipates the heat through the vents configured under the reference silencer chamber.

[0081] S204, generating a third sound wave by reflecting the second sound wave through the second reflection surface, and at least partially canceling the third sound wave with the fifth sound wave, the fifth sound wave is generated by reflecting the fourth sound wave through the first reflection surface, and the fourth sound wave is a noise sound wave that is generated by performing a heat dissipation operation on the target charging pile after emitting the first sound wave and is incident from the air medium toward the first reflection surface.

The focal position area of ​​the corresponding concave reflecting surface is emitted toward the first reflecting surface to enhance the parallel effect of the noise sound wave after being reflected by the first reflecting surface, so that the noise sound wave can return more parallelly to enhance the effect of noise sound wave reduction processing; the second sound wave is reflected by the second reflecting surface to generate a third sound wave, and the third sound wave and the fifth sound wave are at least partially offset by sound waves, the fifth sound wave is generated by the first reflecting surface reflecting the fourth sound wave, and the fourth sound wave is a noise sound wave incident from the air medium toward the first reflecting surface after the first sound wave is emitted by performing a heat dissipation operation on the target charging pile, so that the third sound wave reflected by the second reflecting surface has a π phase mutation relative to the fifth sound wave reflected by the first reflecting surface, and then the third sound wave and the fifth sound wave can be at least partially offset by sound waves, thereby achieving noise sound wave reduction processing. At the same time, in the process of noise sound wave reduction processing of the charging pile, no additional noise reduction equipment is required, the structure is simple and reliable, the cost is low, and the charging piles of different shapes can be adapted by adjusting the inclination angle of the first reflecting surface, and the heat dissipation process of the charging pile will not be affected.
