[0001] This utility model belongs to the field of heat dissipation technology of electricity meters, specifically, it relates to a heat pipe heat dissipation system structure for internal components of an electricity meter. Background Technology

[0002] An electricity meter, also known as an energy meter or kilowatt-hour meter, is a device used to measure electrical energy consumption. It records the total amount of electrical energy consumed by a user within a certain period, usually measured in kilowatt-hours (kWh). Electricity meters are an indispensable component of the power system, playing a crucial role not only in billing but also in the monitoring and maintenance of the power system.

[0003] The circuit board inside an electricity meter is one of its core components, responsible for tasks such as measuring electrical energy and transmitting data. During normal operation, the electronic components on the circuit board generate heat due to the energy conversion when current passes through resistance. With technological advancements, the integration level of circuit boards is increasing, and the power density of components is also increasing, leading to even more heat generation during operation.

[0004] Overheating of the circuit board can cause a series of problems:

[0005] Accelerated component aging: High temperatures can accelerate the aging process of electronic components on circuit boards, reducing their lifespan.

[0006] Performance degradation: Overheating may cause the performance of components on the circuit board to degrade, affecting the measurement accuracy and stability of the electricity meter.

[0007] Increased failure rate: Prolonged overheating may cause thermal expansion of the circuit board, leading to solder joint breakage or component damage, thus increasing the failure rate.

[0008] Safety hazards: Overheating of the circuit board may also cause fires and other safety accidents, posing a threat to the safety of users and equipment. Utility Model Content

[0009] In view of this, the present invention provides a heat pipe cooling system structure for internal components of an electricity meter, which can solve the problem of overheating of the internal circuit board of the electricity meter, improve the performance and service life of the electricity meter, and reduce the safety hazards of the electricity meter.

[0010] This utility model is implemented as follows:

[0011] This utility model provides a heat pipe cooling system structure for internal components of an electricity meter, including an electricity meter with a circuit board inside. The circuit board is fixedly connected to the center of the electricity meter by a support rod. The rear side of the circuit board is in close contact with a heat-conducting plate, wherein the rear side of the heat-conducting plate is in close contact with a heat-conducting pipe. The heat-conducting pipe has multiple openings facing the rear side of the electricity meter near the rear side of the electricity meter. A fan is installed at each opening, and the airflow direction of the fan is perpendicular to the opening direction of the heat-conducting pipe. The fan is fixed to the side wall of the electricity meter.

[0012] Based on the above technical solution, the heat pipe heat dissipation system structure for internal components of an electricity meter of this utility model can be further improved as follows:

[0013] The heat-conducting plates are located on the rear side and the left and right sides of the circuit board, forming a C-shape with the opening facing the front of the electricity meter. There are heat-conducting pipes on the left, right, and rear sides of the heat-conducting plates, and the top cross-section of the heat-conducting pipes is C-shaped.

[0014] Furthermore, both ends of the heat pipe are sealed.

[0015] Furthermore, the heat pipe is internally continuous and arranged in an S-shape on the rear side of the heat-conducting plate.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are: the internal connection ensures smooth flow of the heat transfer medium and efficient heat conduction.

[0017] The S-shaped arrangement increases the contact area with the heat-conducting plate, fully absorbing heat. It also extends the length of the heat pipe within a limited space, allowing more time and path for heat transfer, thus improving heat dissipation efficiency. At the same time, its placement on the back of the heat-conducting plate does not occupy front space, which is conducive to compact equipment design.

[0018] Furthermore, the heat-conducting pipes are arranged horizontally in a C-shape, with each pipe connected to the others by a vertical pipe, and the horizontal and vertical pipes are interconnected at their connection points.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are: the array arrangement can evenly distribute heat and improve the overall heat dissipation effect.

[0020] The four-way connection at the intersection makes heat transfer more flexible, allowing heat to be quickly conducted in all directions, avoiding local overheating, and further improving the stability and reliability of heat dissipation.

[0021] Furthermore, the heat pipe has a rectangular parallelepiped cross-section.

[0022] Furthermore, the heat pipe is in contact with the heat-conducting plate.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the heat pipe and the heat plate to be in contact with each other, the efficiency of heat transfer is improved, thereby improving the cooling effect of the electricity meter.

[0024] Furthermore, the heat pipe is made of copper, aluminum, or stainless steel.

[0025] Furthermore, the vertical height of the heat-conducting plate is equal to the height of the electricity meter, and a groove is provided at the contact point between the electricity meter and the heat-conducting plate.

[0026] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting the groove, it is convenient to fix the heat-conducting plate and avoid the heat-conducting plate shifting during use, which would cause damage to the circuit board.

[0027] Furthermore, the thickness of the heat pipe is equal to the distance between the heat-conducting plate and the side wall of the electricity meter.

[0028] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the thickness of the heat-conducting pipe to be equal to the distance between the heat-conducting plate and the side wall of the electricity meter, the diameter area of ​​the heat-conducting pipe is increased, thereby improving the ventilation effect.

[0029] Compared with the prior art, the beneficial effects of the heat pipe heat dissipation system structure for internal components of an electricity meter provided by this utility model are:

[0030] Efficient heat conduction design: By placing the circuit board in close contact with the heat-conducting plate, and then transferring heat from the heat-conducting plate to the heat pipe, this structural design can quickly conduct away the heat generated by the circuit board, reducing the risk of overheating of the circuit board.

[0031] Optimized heat dissipation layout: The S-shaped and C-shaped horizontal arrangement of heat pipes increases the contact area with the heat-conducting plate, extends the heat transfer path, and improves heat dissipation efficiency.

[0032] Compact space utilization: The heat pipes are arranged on the back of the heat-conducting plate, which does not occupy the front space of the electricity meter, thus facilitating the compact design of the equipment.

[0033] Enhanced heat dissipation stability: The heat pipes are internally connected and arranged in an S-shape, and the C-shaped horizontal pipes are connected by vertical pipes. This design allows heat to be distributed evenly, avoids local overheating, and improves the stability and reliability of heat dissipation.

[0034] Flexibility in material selection: Heat pipes can be made of materials such as copper, aluminum, or stainless steel, all of which have good thermal conductivity and can be flexibly selected according to cost and performance requirements.

[0035] Structural stability: The contact area between the heat-conducting plate and the electricity meter has a groove. This design helps to fix the heat-conducting plate and prevent it from shifting during use, thereby protecting the circuit board from damage.

[0036] Improved ventilation: By setting the thickness of the heat-conducting pipe to be equal to the distance between the heat-conducting plate and the side wall of the electricity meter, the diameter area of ​​the heat-conducting pipe is increased, thereby improving the ventilation effect and helping to dissipate heat quickly.

[0037] Fan-assisted cooling: The fan is positioned perpendicular to the opening of the heat pipe, which can effectively draw heat out of the heat pipe and further enhance the heat dissipation effect.

[0038] In summary, this utility model improves the heat dissipation efficiency of the internal components of the electricity meter through a carefully designed heat dissipation structure, which helps to improve the performance and service life of the electricity meter, while also making the design of the electricity meter more compact and stable.
