Description

Technical Field

[0001] This utility model belongs to the technical field of backplate technology for electricity meters, specifically, it relates to a multi-directional heat dissipation hole array type backplate for electricity meters. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy consumption and is widely used in various fields such as homes, industry, and commerce. It accurately measures electricity consumption and plays a crucial role in the rational allocation of power resources by power supply departments, enabling users to understand their own electricity usage, and facilitating electricity bill settlement.

[0003] The backplate of an electricity meter, as an important component, is usually located on the back of the meter. On the one hand, it provides mounting support for the internal components of the meter, ensuring their stable installation; on the other hand, it also plays a role in protecting the internal structure of the meter to a certain extent, preventing external environmental factors from damaging the internal components.

[0004] However, existing electricity meter backplates often have some problems in practical use. Among them, heat dissipation is particularly prominent. Because the internal components of an electricity meter generate heat during operation, an inadequate backplate can lead to insufficient heat dissipation inside the meter. Specifically, this manifests in the following ways:

[0005] Inadequate structure: Some electricity meter back panels lack clear division between the installation area and the heat dissipation area, causing heat to accumulate inside the meter and fail to dissipate effectively. Furthermore, the lack of effective ventilation channels hinders airflow and negatively impacts heat dissipation.

[0006] Poor heat dissipation vents: Traditional heat dissipation vents on the back panel of electricity meters may be straight channels, which result in high airflow resistance, poor airflow, and low heat dissipation efficiency. Moreover, the number, layout, and shape of the vents may not meet the heat dissipation requirements of the electricity meter.

[0007] Inappropriate material selection: Some electricity meter backplates may be made of materials that lack good thermal conductivity or cannot effectively dissipate heat, thus affecting heat dissipation. Furthermore, the surface treatment of the backplate can also affect heat dissipation performance; for example, an overly smooth surface may reduce the contact area between the air and the backplate, hindering heat transfer.

[0008] Lack of active heat dissipation measures: Some electricity meter back panels rely solely on natural heat dissipation without being equipped with active heat dissipation devices such as fans. Under high load or high temperature environments, they cannot dissipate heat in a timely and effective manner, which can easily lead to excessively high internal temperatures of the electricity meter, affecting its normal operation and service life. Utility Model Content

[0009] In view of this, the present invention provides a multi-directional heat dissipation hole array type back plate for electricity meters, which can solve the problem of inconvenient heat dissipation inside the electricity meter.

[0010] This utility model is implemented as follows:

[0011] This utility model provides a multi-directional heat dissipation hole array type backplate for an energy meter, which includes a mounting area and a heat dissipation area. The mounting area is located in the middle of the energy meter and is used to install internal components of the energy meter. The heat dissipation area is used for ventilation. The mounting area and the heat dissipation area are isolated by a baffle. The side of the baffle facing the mounting area has a protrusion for installing internal components of the energy meter. The side of the baffle facing the heat dissipation area has heat dissipation holes arranged in an array on the baffle. The energy meter also has an array of heat dissipation holes around its perimeter. A fan is installed inside the heat dissipation area.

[0012] Based on the above technical solution, the multi-directional heat dissipation hole array type backplate of the present invention can be further improved as follows:

[0013] The heat dissipation hole is provided with a one-way valve on the side facing the baffle, the baffle is provided with a one-way valve on the side facing the installation area, and the one-way valves around the energy meter are located on the outside of the energy meter.

[0014] Furthermore, the one-way valve includes a rotating shaft and a baffle plate. The rotating shaft is located on one side of the heat dissipation hole and is fixedly connected to the heat dissipation hole. The baffle plate is a flat plate with the same cross-sectional shape as the heat dissipation hole. The baffle plate is rotatably connected to the baffle plate through the rotating shaft.

[0015] Furthermore, the rotation axis is located above the baffle.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a rotating shaft and baffle, the air inside the heat dissipation zone enters the installation zone through the through holes on the heat dissipation holes, and the air in the installation zone flows out of the installation zone through the heat dissipation holes around the energy meter, forming a complete heat dissipation channel and improving the heat dissipation efficiency of the energy meter.

[0017] Furthermore, the axis of the heat dissipation hole is curved.

[0018] Furthermore, the axis of the heat dissipation hole is curved in an arc shape.

[0019] Enhanced heat dissipation: The arc-shaped axis makes the internal channels of the heat dissipation holes smoother, allowing air to flow through them in a more stable manner. Compared to straight channels, the arc-shaped channels reduce airflow resistance, making airflow smoother and thus improving heat dissipation efficiency. The rough internal surface increases the contact area between the air and the walls of the heat dissipation holes, allowing heat to be transferred to the air more effectively, further enhancing the heat dissipation effect.

[0020] Absorbing dust and protecting internal components of the electricity meter: The rough internal heat dissipation holes act as a dust filter. When air carries dust into the heat dissipation holes, the rough surface makes it easier for the dust to adhere to the hole walls, thus reducing the amount of dust entering the electricity meter. This is crucial for protecting the electronic components inside the electricity meter, as dust accumulation can lead to short circuits, poor heat dissipation, and other problems, affecting the normal operation and lifespan of the electricity meter.

[0021] Improved structural stability: The arc-shaped axis is structurally more stable than a straight channel. When subjected to external forces, the arc-shaped structure can better disperse stress, reducing deformation or damage to the backplate caused by stress. At the same time, the rough internal surface can also increase the bonding force between the heat dissipation holes and the backplate material, improving the overall structural stability.

[0022] Furthermore, the axis of the heat dissipation hole is curved in a wavy shape.

[0023] Enhanced heat dissipation performance: The wavy axis increases the length of the heat dissipation channel. As air flows through the wavy ventilation holes, the path is lengthened, and the contact time with the hole walls increases accordingly. This allows heat to be transferred to the air more efficiently, thus improving heat dissipation efficiency. The wavy channel also promotes air turbulence. Compared to straight channels, the wavy channel generates turbulence during airflow, enhancing air mixing and heat exchange. Turbulent air can carry away heat more quickly, further improving the heat dissipation effect.

[0024] Highly efficient dust absorption: The rough internal surface increases the surface area for dust adhesion. When air carrying dust enters the heat dissipation holes, the rough hole walls provide more adhesion points for the dust. Compared to smooth surfaces, rough surfaces can more effectively capture and adsorb dust, reducing the likelihood of dust entering the inside of the energy meter; the wavy structure increases the chance of dust colliding with the hole walls. As air flows through the wavy channels, dust constantly collides with the hole walls due to changes in airflow. This collision makes it easier for dust to be captured by the hole walls, thereby improving dust absorption efficiency.

[0025] Improved Structural Strength: The wavy design enhances the overall rigidity of the backplate. The wavy ventilation holes act like reinforcing ribs within the backplate, improving its bending and torsional strength. This makes the meter backplate more stable and reliable under external pressure and vibration. The rough internal structure helps strengthen the material bonding. The rough hole walls create a tighter bond with the backplate material, improving the overall integrity of the ventilation holes and the backplate. During long-term use, the ventilation holes are less likely to loosen or detach, ensuring the structural stability of the meter.

[0026] Furthermore, the axial curvature of the heat dissipation hole is a Fibonacci curve.

[0027] The beneficial effects of adopting the above-mentioned improved scheme are as follows: Unique heat dissipation advantages: The Fibonacci sequence curve has characteristics such as self-similarity and the golden ratio. This special curve shape allows for more complex and varied airflow within the heat dissipation holes. When air flows through the heat dissipation holes shaped like the Fibonacci sequence curve, multiple small vortices and turbulent regions are formed, increasing the contact area between the air and the heat dissipation hole wall and the heat exchange efficiency, thereby significantly improving the heat dissipation effect; the relatively long axis length of the heat dissipation holes in the Fibonacci sequence curve can prolong the residence time of air within the heat dissipation holes, allowing more opportunities for heat to be transferred to the air, further enhancing the heat dissipation performance.

[0028] Highly efficient dust absorption: The rough internal surface provides more adhesion points for dust. When air carrying dust enters the heat dissipation holes, the rough hole walls increase the friction between the dust and the hole walls, making it easier for dust to adhere to the holes and effectively reducing the likelihood of dust entering the meter. The Fibonacci sequence curve shape of the heat dissipation holes makes the airflow more irregular, allowing dust to collide and rub against the hole walls more easily in this complex airflow. This collision and friction gradually reduces the kinetic energy of the dust, eventually trapping it within the hole walls and improving dust absorption efficiency.

[0029] Enhanced structural stability: The Fibonacci sequence-shaped heat dissipation holes increase the structural complexity and strength of the electricity meter's backplate to some extent. This special curved shape can disperse external stress, improving the backplate's resistance to deformation and seismic performance; the rough internal structure can increase the bonding force between the heat dissipation holes and the backplate material, making the heat dissipation holes more firmly fixed to the backplate, less prone to loosening or falling off, thus ensuring the overall structural stability of the electricity meter.

[0030] Reduced noise propagation: The Fibonacci sequence curve-shaped heat dissipation holes can make the airflow more dispersed and uniform, reducing the concentrated and high-speed flow areas of the airflow, thereby reducing the noise generated by the airflow.

[0031] The rough interior surface can absorb some of the noise energy, further reducing noise propagation. This noise reduction effect is very important for noise-sensitive environments, such as homes and offices.

[0032] Furthermore, the baffle is made of plastic.

[0033] Furthermore, the interior of the heat dissipation holes is rough.

[0034] Compared with the prior art, the beneficial effects of the multi-directional heat dissipation hole array type energy meter backplate provided by this utility model are:

[0035] High-efficiency heat dissipation: The division between the installation area and the heat dissipation area clearly defines the functional zones, with the heat dissipation area providing dedicated space for heat dissipation. A fan is installed inside the heat dissipation area to actively promote airflow and accelerate heat removal. The array of heat dissipation holes on the baffle and around the electricity meter form multi-directional heat dissipation channels, increasing the heat dissipation area and pathways, allowing heat to dissipate quickly from multiple directions. The axes of the heat dissipation holes are curved; whether circular, wavy, or Fibonacci curves, they all enhance the heat dissipation effect in different ways. Circular channels reduce airflow resistance, making airflow smoother; wavy axes increase the length of the heat dissipation channels and promote air turbulence, enhancing heat exchange capacity; Fibonacci curves make airflow more complex and variable, increasing contact area and heat exchange efficiency, while also extending air residence time, further improving heat dissipation performance.

[0036] Dust protection: The rough surface inside the heat dissipation holes increases the adhesion area for dust. When air carries dust into the heat dissipation holes, the rough surface makes it easier for the dust to adhere to the hole walls, reducing the amount of dust entering the electricity meter. The heat dissipation holes with different shapes and curves, such as wavy and Fibonacci curves, increase the chance of dust colliding with the hole walls, making it easier for dust to be captured. This plays a good role in dust filtration, protecting the internal electronic components of the electricity meter and avoiding problems such as short circuits and poor heat dissipation caused by dust accumulation, thus extending the service life of the electricity meter.

[0037] Structural Stability: A baffle separates the installation area and the heat dissipation area. The protrusion on the baffle facing the installation area is used to house the internal components of the energy meter, increasing structural stability and functionality. The arc-shaped, wavy, and Fibonacci curve-shaped heat dissipation holes provide greater structural stability, better dispersing stress and reducing deformation or damage to the backplate under load. The rough internal structure increases the bonding force between the heat dissipation holes and the backplate material, improving overall structural stability. The wavy shape also enhances the overall rigidity of the backplate, acting as a reinforcing rib and improving its bending and torsional strength. The Fibonacci curve-shaped heat dissipation holes increase the structural complexity and strength of the backplate, dispersing external stress and improving resistance to deformation and seismic performance.

[0038] Noise reduction: The heat dissipation holes with different shapes and curves make the airflow more dispersed and uniform, reducing the concentrated and high-speed flow areas of airflow, thereby reducing the noise generated by airflow; the rough internal surface can absorb some noise energy, further reducing the transmission of noise, and providing quieter use conditions for noise-sensitive environments such as homes and offices.

[0039] One-way valves: One-way valves are installed on the heat dissipation holes. The one-way valve on the baffle is located on the side facing the installation area, and the one-way valves around the energy meter are located on the outside of the energy meter, forming a complete heat dissipation channel. Air inside the heat dissipation area enters the installation area through the through holes on the heat dissipation holes, and air inside the installation area flows out of the installation area through the heat dissipation holes around the energy meter, ensuring the directionality of airflow and improving heat dissipation efficiency. The one-way valve consists of a rotating shaft and a baffle, with a simple and practical structure. The baffle is rotatably connected to the baffle via the rotating shaft, and can automatically open and close according to the direction of airflow, ensuring the normal operation of the heat dissipation channel.

[0040] Material selection: The baffle is made of plastic, which has advantages such as good insulation, light weight, and low cost. At the same time, plastic is easy to process and mold, and can meet the design requirements of complex shapes. Attached Figure Description

[0072] Furthermore, in the above technical solution, the interior of the heat dissipation hole 4 is rough.

[0073] Specifically, the principle of this utility model is as follows: 1. Heat dissipation principle

[0074] The installation area and heat dissipation area are divided as follows: The installation area is located in the middle of the electricity meter and is used to install the internal components of the electricity meter, which generate heat during operation. The heat dissipation area is specifically for ventilation and heat dissipation, and is isolated from the installation area by a baffle to prevent heat from accumulating inside the electricity meter.

[0075] The function of the fan: The fan installed inside the heat dissipation area actively promotes airflow. When the fan is running, it draws in cooler outside air into the heat dissipation area.

[0076] The ventilation holes on the baffle: The array of ventilation holes on the baffle connects the mounting area and the heat dissipation area. When the fan draws air into the heat dissipation area, the air is forced through the ventilation holes by pressure because the one-way valve on the baffle is located on the side facing the mounting area. The axis of the ventilation holes is curved; whether it is an arc, a wave, or a Fibonacci curve, it can enhance the heat dissipation effect in different ways.

[0077] Arc-shaped heat dissipation holes: Their internal channels are smoother, reducing airflow resistance and allowing for smoother airflow, thus improving heat dissipation efficiency. At the same time, the rough internal surface increases the contact area between the air and the hole walls, allowing heat to be transferred to the air more effectively.

[0078] Wavy ventilation holes: These increase the length of the heat dissipation channel, extending the airflow path and increasing the contact time with the hole walls, allowing for more efficient heat transfer. Furthermore, the wavy channel promotes air turbulence, enhancing air mixing and heat exchange, and accelerating heat removal.

[0079] Fibonacci curve heat dissipation holes: Utilizing the self-similarity of the Fibonacci sequence curve and the golden ratio, the airflow becomes more complex and varied, forming multiple small vortices and turbulent regions, increasing the contact area between the air and the heat dissipation hole walls and improving heat exchange efficiency. Simultaneously, the longer axial length extends the residence time of air within the heat dissipation holes, allowing for more opportunities for heat transfer.

[0080] Heat dissipation holes around the electricity meter: Hot air in the installation area flows out through the array of heat dissipation holes around the electricity meter. One-way valves around the electricity meter are located on the outside to ensure one-way airflow, forming a complete heat dissipation channel together with the heat dissipation holes on the baffle and the fan, accelerating heat dissipation.

[0081] II. Dust Filtration Principle

[0082] Rough internal ventilation holes: The rough surface inside the ventilation holes provides more adhesion points for dust. When air carries dust into the ventilation holes, the rough hole walls increase the friction between the dust and the hole walls, making it easier for the dust to adhere to the hole walls.

[0083] The functions of different shaped heat dissipation holes:

[0084] Wavy ventilation holes: Increase the chance of dust colliding with the hole walls. When air flows in the wavy channels, dust will constantly collide with the hole walls due to the changes in airflow, making it easier for dust to be captured by the hole walls.

[0085] Fibonacci curve heat dissipation holes: make the airflow more irregular, and dust is more likely to collide and rub against the hole walls in the complex airflow, reducing the kinetic energy of the dust and eventually being captured by the hole walls.

[0086] III. Structural Stability Principle

[0087] The function of the baffle: The baffle between the installation area and the heat dissipation area not only serves as an isolation, but its protrusion facing the installation area is used to install the internal components of the energy meter, increasing the stability of the structure.

[0088] The influence of the shape of the heat dissipation holes:

[0089] Arc-shaped ventilation holes: These provide greater structural stability, better stress distribution, and reduce deformation or damage to the backplate caused by stress. The rough internal surface also increases the bonding strength between the ventilation holes and the backplate material, improving overall structural stability.

[0090] Wavy ventilation holes: The wavy shape enhances the overall rigidity of the backplate, acting like a reinforcing rib and improving its bending and torsional strength. The rough internal structure ensures a tighter bond between the hole walls and the backplate material, improving the overall integrity of the ventilation holes and the backplate, making it less prone to loosening or detachment.

[0091] Fibonacci curve heat dissipation holes: The special curved shape increases the structural complexity and strength of the electricity meter backplate, dispersing external stress and improving the backplate's resistance to deformation and shock. The rough internal structure makes the heat dissipation holes more firmly fixed to the backplate, ensuring the overall structural stability of the electricity meter.

[0092] IV. Noise Reduction Principle

[0093] The influence of the shape of the heat dissipation holes:

[0094] The wave-shaped and Fibonacci curve ventilation holes make the airflow more dispersed and uniform, reducing the concentration of airflow and the high-speed flow area, thereby reducing the noise generated by the airflow.

[0095] The function of an internally rough surface: An internally rough surface can absorb some noise energy, further reducing the transmission of noise and providing quieter usage conditions for noise-sensitive environments such as homes and offices.
