Efficient heat dissipation structure of electric energy meter

Abstract

This utility model relates to the field of electricity meter technology, and particularly to a high-efficiency heat dissipation structure for electricity meters. It includes an electricity meter housing, a cover hinged to the front left end of the housing, a fixed lug fixedly connected to the upper end of the housing, and a fixed plate fixedly connected to the lower end of the housing. Both the front ends of the lugs and the fixed plate have through holes. Mounting components are fitted onto the middle left and right ends of the housing. This high-efficiency heat dissipation structure activates the cooling fan within the heat dissipation component when the load increases and high-efficiency heat dissipation is required. The fan operates stably within the fixed frame via a mounting rod and a mounting base, utilizing the gap between itself and the inner wall of the fixed frame to generate an adsorption force. This force quickly introduces internal heat into the heat dissipation component through the first heat dissipation groove, heat dissipation fins, and mounting holes, and finally dissipates efficiently through the second dust filter, significantly accelerating the heat dissipation speed.

Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and in particular to an efficient heat dissipation structure for electricity meters. Background Technology

[0002] Electricity meters are essential measuring instruments used to measure electricity consumption. They are widely used in various electricity consumption scenarios, including households, businesses, and industrial production. Their measurement accuracy and operational stability are directly related to the rational allocation of electricity resources and fair billing. With the continuous growth of social electricity load and the diversification of smart meter functions (such as data transmission and remote control), the power consumption of the electronic components inside the electricity meter is gradually increasing, and a large amount of heat is generated during operation. However, traditional electricity meters rely solely on simple ventilation holes on the outer casing for natural heat dissipation, resulting in low efficiency. During peak electricity loads, heat accumulates rapidly inside the meter, easily leading to overheating of components. This not only affects metering accuracy but also accelerates component aging and can even cause short circuits or burnouts, severely impacting the meter's lifespan and electrical safety. Therefore, we have developed a highly efficient heat dissipation structure for electricity meters. Utility Model Content

[0003] The main objective of this invention is to provide a high-efficiency heat dissipation structure for an electricity meter, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency heat dissipation structure for an electricity meter includes an electricity meter housing. A cover is movably installed on the front left end of the electricity meter housing via a hinge. A fixing lug is fixedly connected to the upper end of the electricity meter housing, and a fixing plate is fixedly connected to the lower end of the electricity meter housing. The front ends of the fixing lug and the fixing plate are both provided with through fixing holes. Mounting components are fitted onto the middle left and middle right ends of the electricity meter housing.

[0005] Preferably, the mounting assembly includes a mounting plate and fixing bolts. The upper right end of the mounting plate on the right side has a through mounting hole, and a heat dissipation assembly is fixedly sleeved in the mounting hole. The lower right end of the mounting plate on the right side has a through second heat dissipation groove, and the inner wall of the second heat dissipation groove is embedded with a first dustproof mesh. The four corners of the right end of the mounting plate on the right side each have a through second screw hole.

[0006] By adopting the above technical solution, the heat dissipation component and the second heat dissipation slot work together to form a dual heat dissipation channel, and the first dustproof net blocks dust from entering.

[0007] Preferably, the heat dissipation assembly includes a fixed frame, a plurality of mounting rods are fixedly connected to the inner wall of the fixed frame, a fixed seat is fixedly connected to the plurality of mounting rods, a heat dissipation fan is fixedly installed at the left end of the fixed seat on the right side, a second dustproof mesh is embedded at the right end of the fixed frame on the right side, and the fixed frame is fixedly fitted into the mounting hole.

[0008] By adopting the above technical solution: the mounting rod and fixing seat in the fixed frame provide stable support for the cooling fan, the cooling fan accelerates heat dissipation, and the second dustproof net prevents dust from entering the core heat dissipation components.

[0009] Preferably, a plurality of the mounting rods are arranged in a circular array around the center of the fixing frame, and there is a gap between the cooling fan and the inner wall of the fixing frame.

[0010] By adopting the above technical solution: the mounting rod of the ring array enhances the stability of the fixed frame structure, and the gap between the heat dissipation fan and the fixed frame ensures smooth airflow and improves heat dissipation efficiency.

[0011] Preferably, the outer casing of the electricity meter includes a housing, with mounting grooves at both the left and right ends of the housing. A first heat dissipation groove is formed in the middle of the inner wall of each of the two mounting grooves, and a first screw hole is formed at each of the four corners of the inner wall of each of the two mounting grooves. Several heat dissipation fins are fixedly connected to the inner wall of each of the two first heat dissipation grooves.

[0012] By adopting the above technical solution, the first heat dissipation groove and heat dissipation fins increase the heat dissipation area and accelerate the transfer of heat from the inside of the shell to the outside.

[0013] Preferably, the heat dissipation fins are all inclined and distributed at equal intervals in pairs.

[0014] By adopting the above technical solution, the inclined and equidistantly distributed heat dissipation fins increase the contact area with the air, promote rapid heat dissipation, and improve the natural heat dissipation effect.

[0015] Preferably, the mounting plate is movably sleeved in the corresponding mounting groove, and four fixing bolts are provided. The outer surfaces of the four fixing bolts are respectively threaded to the inner wall surfaces of the four corresponding second screw holes and extend into the four corresponding first screw holes.

[0016] By adopting the above technical solution, the mounting plate and the mounting groove are fitted together, and the threaded connection of the fixing bolts is combined to achieve a firm fixation of the mounting components, which facilitates disassembly and maintenance.

[0017] Preferably, the mesh size of the first dustproof mesh and the mesh size of the second dustproof mesh are both smaller than the gap size between each pair of heat dissipation fins.

[0018] By adopting the above technical solution, the mesh size of the first dustproof mesh and the mesh size of the second dustproof mesh are smaller than the gap between the heat dissipation fins. This ensures that the heat dissipation channel is unobstructed while effectively blocking dust from entering and preventing the heat dissipation components from being contaminated and blocked.

[0019] Compared with the prior art, the present invention has the following beneficial effects: In this invention, during natural heat dissipation, the heat inside the casing is transferred to the inclined and equidistantly distributed heat dissipation fins through the first heat dissipation groove. After increasing the contact area, the heat diffuses to the mounting components through the gaps between the heat dissipation fins, and then dissipates naturally through the first dustproof net of the second heat dissipation groove, achieving basic heat dissipation. When the load increases and efficient heat dissipation is required, the cooling fan of the heat dissipation component is activated. It operates stably within the fixed frame through the mounting rod and the fixed seat, and uses the gap with the inner wall of the fixed frame to generate an adsorption force, quickly introducing the internal heat into the heat dissipation component through the first heat dissipation groove, heat dissipation fins, and mounting holes. Finally, it is efficiently dissipated through the second dustproof net, greatly accelerating the heat dissipation speed. At the same time, because the mesh size of the first and second dustproof nets is smaller than the gap between the heat dissipation fins, they can effectively block dust from entering, preventing the heat dissipation component and internal components from being contaminated, ensuring continuous and effective heat dissipation, extending the service life of the electricity meter, and ensuring accurate metering and electrical safety.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-8 This utility model provides a technical solution: A high-efficiency heat dissipation structure for an electricity meter includes an electricity meter housing 1, a cover 2 that is movably mounted on the front left end of the electricity meter housing 1 via a hinge, a fixing lug 3 that is fixedly connected to the upper end of the electricity meter housing 1, a fixing plate 4 that is fixedly connected to the lower end of the electricity meter housing 1, fixing holes 5 that pass through the front end of the fixing lug 3 and the front end of the fixing plate 4, and mounting components 6 that are sleeved on the middle left and middle right ends of the electricity meter housing 1.

[0026] In this embodiment, the mounting component 6 includes a mounting plate 61 and fixing bolts 67. The upper right end of the right mounting plate 61 has a through-hole 62, into which a heat dissipation component 63 is fixedly fitted. The lower right end of the right mounting plate 61 has a through-hole 64, with a first dustproof mesh 65 embedded in its inner wall. The four corners of the right end of the right mounting plate 61 each have through-holes 66. The heat dissipation component 63 includes a fixing frame 631, with several mounting rods 632 fixedly connected to its inner wall. A fixing seat 633 is fixedly connected to all mounting rods 632. A cooling fan 634 is fixedly mounted on the left end of the right fixing seat 633. A second dustproof mesh 635 is embedded in the right end of the right fixing frame 631. The fixing frame 631 is fixedly fitted into the mounting hole 62. The mounting rods 632 are arranged in a circular array around the center of the fixing frame 631. There is a gap between the cooling fan 634 and the inner wall of the fixing frame 631; the outer casing 1 of the electricity meter includes a housing 11, with mounting grooves 12 at both the left and right ends of the housing 11. The inner wall of each of the two mounting grooves 12 has a first heat dissipation groove 13 that passes through both the inside and outside. The inner wall of each of the two mounting grooves 12 has a first screw hole 14 at each of the four corners. Several heat dissipation fins 15 are fixedly connected to the inner wall of each of the two first heat dissipation grooves 13. The several heat dissipation fins 15 are all inclined and distributed at equal intervals in pairs. The mounting plate 61 is movably sleeved in the corresponding mounting groove 12. Four fixing bolts 67 are provided. The outer surfaces of the four fixing bolts 67 are respectively threaded to the inner wall of the four corresponding second screw holes 66 and extend into the four corresponding first screw holes 14. The mesh size of the first dustproof mesh 65 and the mesh size of the second dustproof mesh 635 are both smaller than the gap between the several heat dissipation fins 15 in pairs.

[0027] It should be noted that this utility model is a high-efficiency heat dissipation structure for an electricity meter. During installation, the two mounting plates 61 are aligned with the mounting grooves 12 at the left and right ends of the electricity meter housing 1, respectively. Fixing bolts 67 are screwed into the first screw hole 14 through the second screw hole 66 to fix the mounting assembly 6 to the electricity meter housing 1. The electricity meter housing 1 is then installed in the designated position through the fixing ears 3 and the fixing holes 5 on the fixing plate 4. The housing cover 2 is then closed to complete the overall fixation. During use, during natural heat dissipation, heat is transferred through the first heat dissipation groove 13 in the mounting grooves 12 at the left and right ends of the housing 11 to several heat dissipation fins 15. Because the heat dissipation fins 15 are inclined and evenly distributed in pairs, the contact area with the air is increased. Heat diffuses through the gaps in the heat dissipation fins 15 to the mounting assembly 6, and then naturally dissipates through the mesh of the first dustproof mesh 65 on the inner wall of the second heat dissipation groove 64, achieving basic heat dissipation. When the electricity meter load increases and high-efficiency heat dissipation is required, the two cooling fans 6 of the heat dissipation assembly 63 in the mounting assembly 6 are activated. 34. The cooling fan 634 operates stably within the fixed frame 631 via the mounting rod 632 and the fixing base 633. Due to the gap between the cooling fan 634 and the inner wall of the fixed frame 631, a continuous adsorption force is generated. Under the action of the adsorption force, the heat inside the electricity meter is quickly guided to the first heat dissipation slot 13 and the heat dissipation fins 15, enters the heat dissipation assembly 63 through the mounting hole 62, and is finally efficiently dissipated through the mesh of the second dustproof net 635 at the right end of the fixed frame 631, accelerating the heat dissipation speed. During the entire heat dissipation process, the first dustproof net 65 and the second dustproof net 635, because their mesh holes are smaller than the gaps of the heat dissipation fins 15, can effectively prevent dust from entering the inside of the electricity meter casing 1, ensuring the cleanliness and normal operation of the heat dissipation assembly 63 and internal components. If maintenance of the mounting assembly 6 is required, unscrew the fixing bolts 67 at the four corners of the mounting plate 61, remove the mounting plate 61 from the mounting slot 12, and then clean or replace the cooling fan 634, the first dustproof net 65, and the second dustproof net 635. After maintenance, reinstall and fix them.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
