Description

Technical Field

[0001] The utility model relates to the technical field of instrument equipment, in particular to an electric energy meter with a heat dissipation mechanism. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy. It is also called an electric meter, a fire meter, or a kilowatt-hour meter. It refers to an instrument that measures various electrical quantities.

[0003] At present, the Chinese utility model patent application with the publication date of November 10, 2023 and the publication number CN219997162U proposes an electric energy meter. Compared with the prior art that uses screws to fix the wiring cover to the terminal block, the wiring cover and the terminal block are relatively fixed by the locking protrusion and the locking groove. In order to close the terminal block, no additional parts are required, the number of parts is reduced, and the manufacturing cost is reduced. Moreover, since the wiring cover can be rotatably connected to the box body, the electric energy meter does not need to be completely disassembled after leaving the factory before installing and wiring the electric energy meter, thereby avoiding the problem of easy loss of parts during the installation of the electric energy meter. In addition, the wiring cover can be locked by the locking protrusion and the locking groove, and the wiring cover can be prevented from being accidentally or abnormally opened during the wiring protection of the normally closed terminal block, thereby forming an effective closed protection for the wiring.

[0004] However, after working for a long time, the circuit boards and electrical components inside the meter box will generate a lot of heat, causing the temperature to rise. If the heat is not dissipated for a long time, it will have an adverse effect on the internal components and circuit boards of the meter box, and may also affect the reading accuracy of the meter dial and even cause circuit failure. Summary of the invention

The bottom end of the heat-conducting pipe is inserted into the side of the heat dissipation part of the data processing device of the electric energy meter.

[0031] An electric energy meter is an instrument used to measure electric energy. It is also called an electric meter, a fire meter, or a kilowatt-hour meter. It refers to an instrument that measures various electrical quantities.

[0032] However, after working for a long time, the circuit boards and electrical components inside the meter box will generate a lot of heat, causing the temperature to rise. If the heat is not dissipated for a long time, it will have an adverse effect on the internal components and circuit boards of the meter box, and may also affect the reading accuracy of the meter dial and even cause circuit failure.

[0033] Based on this, in order to improve the problem of poor heat dissipation of the electric energy meter existing in the related art, the embodiment of the present application provides the following solution.

[0034] The embodiment of the present application provides an electric energy meter with a heat dissipation mechanism, comprising:

[0035] An electric meter body 10, a heat dissipation structure 20 and a waterproof component 30, wherein the electric meter body 10 includes a box body 11 and a data processing device 12, wherein a receiving cavity 13 is provided in the box body 11, wherein the data processing device 12 is provided in the receiving cavity 13, wherein the heat dissipation structure 20 includes a fan 21, a heat dissipation cover 22 and a plurality of heat-conducting pipe fittings 23, wherein the fan 21 is provided on a side wall of one side of the receiving cavity 13, wherein an air inlet 14 accompanying the fan 21 is provided on one side of the box body 11, and an air outlet 15 is provided on the other side, wherein the heat dissipation cover 22 is fixed to one side of the box body 11, wherein an evaporation cavity 222 is formed in the heat dissipation cover 22, wherein a plurality of air flow holes are provided on the heat dissipation cover 22, wherein the heat-conducting pipe fittings 23 are installed on the heat dissipation cover 22, wherein one end of the heat-conducting pipe fittings 23 penetrates through the evaporation cavity 222 and extends into the data processing device 12, and the other end penetrates through the evaporation cavity 222 and extends to the outside thereof.

[0036] As can be seen from the above, an electric energy meter with a heat dissipation mechanism provided in an embodiment of the present application is: when the data processing device 12 inside the electric energy meter box needs to dissipate heat after working for a long time, the fan 21 is started to promote the gas circulation in the accommodating chamber 13, so that the data processing device 12 dissipates heat, and the outside air enters the accommodating chamber 13 from the air inlet 14 and flows out from the air outlet 15 to cool the data processing device 12. The bottom end of the heat-conducting pipe 23 is inserted into the side of the heat dissipation part of the data processing device 12 of the electric energy meter. The heat generated during the operation of the electric energy meter is dissipated through the heat-conducting pipe 23, so as to achieve the effect of heat dissipation of the data processing device 12; multiple air flow holes can accelerate the circulation of gas in the evaporation chamber 222, improve the heat dissipation effect of the heat-conducting pipe 23, and can bring out the heat in the inner electric energy meter faster; therefore, the arrangement of the fan 21, the heat dissipation cover 22 and the multiple groups of heat-conducting pipes 23 accelerates the circulation of gas in the accommodating chamber 13, improves the heat dissipation effect of the heat-conducting pipe 23, and can bring out the heat in the inner electric energy meter faster.

[0037] Optionally, in some embodiments, see Figures 2 to 3 Filters 17 are provided at the air inlet 14 and the air outlet 15 on the box body 11, and a protective cover 33 is provided on the box body 11 for protection, and a vent 331 is provided at the bottom of the protective cover 33.

[0038] With such arrangement, when the fan 21 is started, external dust is easily flowed toward the direction close to the accommodating chamber 13 under the action of the fan 21, and is blocked by the filter 17 at the air inlet 14. Under normal circumstances, when the dust mixed in the air flows toward the direction close to the accommodating chamber 13, it will be blocked by the filter 17; when the electric meter box is in an outdoor environment and encounters rain, the protective cover 33 is used to reduce the probability of rainwater entering the accommodating chamber 13 from the air inlet 14 and the air outlet 15. The setting of the vent 331 facilitates air circulation. Therefore, the setting of the filter 17 and the protective cover 33 is used to protect the electric energy meter.

[0039] Optionally, in some embodiments, see Figures 2 to 4 The heat-conducting pipe 23 includes a heat-conducting section 231, an evaporating section 232 and a condensing section 233. The heat-conducting section 231 is inserted into the data processing device 12, the evaporating section 232 is located in the evaporating chamber 222, the condensing section 233 runs through the evaporating chamber 222, and is arranged outside the heat dissipation cover 22. A condensing block 24 is sleeved on the outer wall of the condensing section 233. The heat-conducting section 231, the evaporating section 232 and the condensing section 233 are integrally formed.

[0040] In this arrangement, the heat conducting section 231 is inserted into the data processing device 12, and the high temperature of the data processing device 12 can be brought out through the heat conducting section 231 and conducted to the evaporation section 232. The evaporation section 232 is located in the evaporation chamber 222, which accelerates the circulation and speed of air at the evaporation point, accelerates the evaporation of heat in the evaporation section 232, and accelerates the speed at which the heat from the heat conducting section 231 is conducted to the evaporation section 232, so that the oil temperature in the data processing device 12 is quickly reduced; the condensation section 233 is connected to the condensation block 24, and is cooled by the condensation block 24; therefore, the arrangement of the heat conducting section 231, the evaporation section 232 and the condensation section 233 can improve the heat dissipation effect of the electric meter.

[0041] Optionally, in some embodiments, please read Figures 3 to 5 A water-absorbing pad 16 is provided on the inner wall of the accommodating cavity 13 .

[0042] With such arrangement, the data processing device 12 inside the electric meter box has a high temperature after working for a long time, and is prone to generate water vapor. The water absorbent pad 16 arranged in the accommodating cavity 13 can absorb the water vapor and extend the service life. The water absorbent pad 16 can be made of silica gel water absorbent material. Hydrogel water absorbent is also called super absorbent. It is a polymer water absorbent material. Its water absorption capacity is stronger than that of silica gel water absorbent and can absorb hundreds of times its own weight of water.

[0043] Optionally, in some embodiments, see Figure 5 to Figure 6 The waterproof component 30 includes a convex plate 31 and a sealing ring 32. The box body 11 includes a front box 111 and a rear box 112. The front box 111 and the rear box 112 are connected by bolts. The convex plate 31 is arranged on a side of the front box 111 close to the rear box 112. A limiting groove 113 is provided on a side of the rear box 112 close to the front box 111. The sealing ring 32 is arranged in the limiting groove 113. The convex plate 31 is arranged in the limiting groove 113 and abuts against the sealing ring 32 to form a seal.

[0044] With such arrangement, when the electric meter box is in an outdoor environment and encounters rain, the rainwater tends to flow into the gap between the front box 111 and the rear box 112 and is blocked by the sealing ring 32. Since the convex plate 31 is arranged in the limiting groove 113 and abuts against the sealing ring 32 to form a seal, it is difficult for rainwater to enter the accommodating cavity 13. Therefore, the arrangement of the convex plate 31 and the sealing ring 32 can protect the electric energy meter and prevent rainwater from outside from entering the accommodating cavity 13.

[0045] Optionally, in some embodiments, see Figure 6 The side walls of the protruding plate 31 are in contact with the inner wall of the limiting groove 113 .

[0046] With such arrangement, when the front box 111 is installed on the rear box 112 , the convex plate 31 can be aligned with the limiting groove 113 , and the front box 111 can be installed on the rear box 112 without being easily dropped, which facilitates the user to fix the bolts on the box body 11 .

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
