Description

Technical Field

[0001] This utility model belongs to the technical field of heat dissipation structure of electricity meters, and specifically relates to an optimized structure of heat dissipation air duct for quick-disassembly electricity meters. Background Technology

[0002] In today's power systems, electricity meters play a crucial role as an important metering device. Electricity meters are instruments used to measure electrical energy; they accurately record the amount of electricity consumed by users, providing a basis for power companies' billing and management.

[0003] Electricity meters sometimes overheat during operation. This overheating can cause a series of problems. First, excessively high temperatures can affect the metering accuracy. The accuracy of an electricity meter is generally temperature-dependent; when the temperature is too high, the internal electronic components may experience performance changes, leading to increased measurement errors. This not only causes economic losses for the power company but may also cause dissatisfaction among users.

[0004] Secondly, overheating can shorten the lifespan of an electricity meter. Prolonged exposure to high temperatures accelerates the aging of internal electronic components, reducing their reliability and stability. This can lead to meter malfunctions, requiring frequent replacements and increasing maintenance costs.

[0005] Furthermore, the overheating of electricity meters can pose safety hazards. Excessive temperature can potentially cause fires and other accidents. This is especially true in enclosed environments, such as inside distribution boxes, where the meter's heat can raise the surrounding temperature and increase the risk of fire. Utility Model Content

[0006] In view of this, the present invention provides an optimized heat dissipation duct structure for a quick-disassembly and assembly type electricity meter, which can reduce the operating temperature of the electricity meter and avoid problems such as reduced accuracy and shortened lifespan due to overheating.

[0007] This utility model is implemented as follows:

[0008] This utility model provides an optimized heat dissipation duct structure for a quick-assembly and disassembly type electricity meter, comprising an electricity meter housing, a metal heat-conducting plate, a dustproof mesh, and heat dissipation fins. The electricity meter housing is a cuboid housing with an opening on the back. The metal heat-conducting plate is embedded inside the electricity meter housing and does not contact the back of the electricity meter housing. The metal heat-conducting plate divides the interior of the electricity meter housing into a functional area and a heat dissipation area. The functional area is a sealed structure, and the heat dissipation area is a cuboid structure with an opening on the back. Heat dissipation fins are also provided on the side of the heat dissipation area near the metal heat-conducting plate. The heat dissipation fins are used for heat conduction, and a dustproof mesh covers the outside of the heat dissipation fins, forming a sealed cuboid structure for the heat dissipation area. The dustproof mesh is detachably connected to the electricity meter housing.

[0009] Based on the above technical solution, the optimized heat dissipation duct structure of the quick-assembly and disassembly type energy meter of this utility model can be further improved as follows:

[0010] The heat dissipation fins are detachably connected to the outer casing of the electricity meter, and the heat dissipation fins are composed of multiple heat dissipation fin assemblies.

[0011] Furthermore, the heat dissipation fin assembly is a cuboid structure with openings at the front and back, and the four sides of the heat dissipation fin assembly are provided with connecting structures for splicing.

[0012] Furthermore, the connection structure includes a male connector and a female connector. The male connector is a strip-shaped protrusion located on the upper side and the right side of the heat dissipation fin assembly, and the female connector is a strip-shaped recess located on the lower side and the left side of the heat dissipation fin assembly.

[0013] Furthermore, the cross-section of the male connector is rectangular.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting up a cuboid, it is convenient to splice the heat dissipation fin assembly.

[0015] Furthermore, the cross-sectional shape of the male connector is trapezoidal, and the short side of the trapezoid is fixedly connected to the heat dissipation fin assembly.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting the male connector to a trapezoidal shape, the connection of multiple heat dissipation fin assemblies is more stable, and the heat dissipation fins are prevented from spreading out during installation and use.

[0017] Furthermore, the upper and right sides of the heat dissipation area are provided with multiple strip-shaped recesses that conform to the shape of the male connector, and the lower and left sides of the heat dissipation area are provided with multiple strip-shaped protrusions that conform to the shape of the female connector recesses.

[0018] Furthermore, the distance between the protrusions and recesses on the upper and lower sides of the heat dissipation area is equal to the lateral length of the heat dissipation fin assembly, and the distance between the protrusions and recesses on the left and right sides of the heat dissipation area is equal to the longitudinal length of the heat dissipation fin assembly.

[0019] Furthermore, a protrusion is provided in the center of the side wall of the dustproof net, and a recess is provided in the heat dissipation area at a position corresponding to the protrusion on the dustproof net, which is adapted to the protrusion.

[0020] Furthermore, the heat dissipation fins are made of aluminum alloy or copper.

[0021] The advantages of using aluminum alloy as a heat dissipation material for electricity meters include: lightweight, facilitating installation and transportation; lower cost, enabling large-scale production; good machinability, allowing for various shapes to meet design requirements; and moderate heat dissipation performance, suitable for general applications. Copper, on the other hand, boasts excellent thermal conductivity, enabling rapid heat transfer, making it suitable for demanding applications; good corrosion resistance, resulting in a long service life; good machinability, allowing for special designs; and an aesthetically pleasing appearance, enhancing the overall quality of the electricity meter. Both have their advantages, and the choice can be made based on actual needs.

[0022] Compared with existing technologies, the beneficial effects of the optimized heat dissipation duct structure for a quick-assembly and disassembly type energy meter provided by this utility model are:

[0023] Quick-assembly and disassembly design: The detachable connection design allows the heat dissipation duct structure of the electricity meter to be quickly disassembled and assembled, facilitating maintenance and cleaning.

[0024] Optimized heat dissipation performance: The use of a metal heat-conducting plate improves the heat conduction efficiency inside the electricity meter, effectively transferring heat from the functional area to the heat dissipation area, and dissipating it through the heat dissipation fins.

[0025] Sealed structure: The sealed structure of the functional area can prevent dust and other impurities from entering, protecting the electronic components inside the electricity meter.

[0026] Dustproof design: The dustproof mesh design of the heat dissipation area can prevent dust from entering the heat dissipation area without affecting the heat dissipation effect.

[0027] Modular heat dissipation fins: The heat dissipation fins are composed of multiple components spliced ​​together, and the number and size of the heat dissipation fins can be flexibly configured as needed to adapt to different heat dissipation requirements.

[0028] Stable connection structure: The connection structure between the heat sink fin components is designed in the form of male and female connectors, which ensures the stability of the connection between the components and prevents them from falling apart during installation and use.

[0029] Trapezoidal male connector: The trapezoidal design of the male connector provides better stability and enhances the connection strength between the heat sink fin assemblies.

[0030] Adaptive protrusion and recess design: The protrusion and recess design of the heat dissipation area corresponds to the connection female head, which allows the heat dissipation fin assembly to be accurately installed in the heat dissipation area, improving the stability of the overall structure.

[0031] The dustproof mesh and the heat dissipation area are matched: the protrusions on the side wall of the dustproof mesh match the recesses of the heat dissipation area, ensuring a tight connection between the dustproof mesh and the heat dissipation area, while also facilitating disassembly and assembly.

[0032] Material selection: The heat dissipation fins are made of aluminum alloy or copper, which have good thermal conductivity and help improve heat dissipation efficiency.

[0033] In summary, this optimized heat dissipation duct structure for quick-assembly electricity meters, through its innovative design, not only improves the heat dissipation efficiency of the electricity meter but also enhances its ease of maintenance and durability. Attached Figure Description
