Description

Technical Field

[0001] This utility model relates to the field of thermal management technology for power equipment, and in particular to a passive cooling outdoor power distribution box. Background Technology

[0002] Outdoor power distribution cabinets are specially designed to house and protect electrical equipment in outdoor environments. Along city streets, they are used to control and distribute power to streetlights, and to install circuit breakers, timers, and control modules for the streetlights. They protect these devices from harsh outdoor conditions and ensure the safe and stable operation of the power system in the outdoor environment.

[0003] Outdoor power distribution cabinets contain a large number of electrical devices that generate heat during operation. If the heat cannot be dissipated in time, the temperature of the equipment will continue to rise. Therefore, outdoor power distribution cabinets are usually equipped with cooling and heat dissipation devices to ensure the normal operation of the electrical equipment.

[0004] In existing technologies, outdoor power distribution boxes are typically equipped with simple cooling devices such as fans and ventilation holes. In terms of energy consumption, due to the lack of precise temperature control and efficient heat exchange design, fans and other equipment often need to run continuously, resulting in significant energy consumption. In terms of heat dissipation, relying solely on natural ventilation or small fans is insufficient to cope with the complex outdoor environment and the concentrated heat generation of equipment inside the box. The heat exchange efficiency is low, and heat cannot be effectively removed in a timely manner. This leads to excessively high temperatures inside the box, accelerating the aging of electrical equipment insulation, shortening equipment lifespan, increasing equipment failure rate, and potentially causing power outages. This affects the stability and reliability of power supply, seriously disrupting various production and daily life activities that rely on electricity. In extreme cases, overheating can even cause fires and other safety accidents, endangering personnel and property safety. Therefore, a passive cooling outdoor power distribution box is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a passive cooling outdoor power distribution box, which aims to improve the problem of energy consumption and poor heat dissipation effect of the existing outdoor power distribution box using fan heat dissipation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A passive cooling outdoor power distribution box includes a base, a box body mounted on top of the base, a top cover mounted on top of the box body, a rainproof auxiliary component between the box body and the top cover, a passive heat dissipation component inside the box body, and a distribution box inside the box body.

[0008] The passive heat dissipation component includes an aluminum base, which is assembled with the distribution box. A heat dissipation pipe is mounted on the side of the aluminum base away from the distribution box, and multiple heat dissipation fins are evenly distributed on the outer periphery of the heat dissipation pipe.

[0009] As a further description of the above technical solution:

[0010] The rainproof auxiliary component includes a rainproof plate, which is fixedly connected to the top of the box. The rainproof plate has an opening on the side away from the box, and a deflector plate is assembled in the middle of the rainproof plate.

[0011] As a further description of the above technical solution:

[0012] An outer shell is fixedly connected to the outside of the box, and the heat dissipation pipe and the heat dissipation fin are both arranged inside the outer shell. A box door is fitted to the outside of the box.

[0013] As a further description of the above technical solution:

[0014] A protective base is fixedly connected to the side of the enclosure away from the distribution box. An air inlet is provided inside the protective base, and an air outlet is provided in the middle of the enclosure.

[0015] As a further description of the above technical solution:

[0016] The rainproof plate has a through groove on the side near the flow guide plate, and the flow guide plate is positioned directly above the heat sink.

[0017] As a further description of the above technical solution:

[0018] The rainproof panel is assembled between the top cover and the housing;

[0019] As a further description of the above technical solution:

[0020] A control module is installed on the side of the distribution box near the box door, and a handle is fixedly connected to the side of the box door away from the box body;

[0021] As a further description of the above technical solution:

[0022] The box body is equipped with an input port and an output port on the side away from the box door, and the input port is connected to the output port through a distribution box.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the aluminum base is tightly assembled with the distribution box, which can efficiently absorb the heat generated by the operation of the power equipment and quickly conduct it to the heat dissipation pipe. The heat dissipation fins on the outer periphery of the heat dissipation pipe utilize the large surface area and the principle of natural convection to dissipate the heat to the surrounding air. Passive heat dissipation is achieved without additional power source consumption, which effectively reduces energy consumption. It can also cope with the concentrated heat generation of the equipment in the cabinet, improve the heat dissipation efficiency, ensure that the power equipment operates in a suitable temperature environment, extend the service life of the equipment, reduce the failure rate, improve the heat dissipation efficiency of the power cabinet, and reduce the heat dissipation cost.

[0025] 2. In this utility model, the rainproof plate and its grooves work together with the diversion plate to effectively block rainwater and guide it to flow along a specific path, preventing rainwater from accumulating on the top of the box or flowing into the box and affecting the heat dissipation of the power cabinet. At the same time, the diversion plate is set directly above the heat sink, which allows rainwater to carry away some of the heat from the surface of the heat sink, accelerating the heat dissipation process of the heat sink and further improving the heat dissipation effect. This ensures that the outdoor power cabinet operates stably in complex outdoor environments, reduces the risk of safety accidents caused by overheating, and protects personnel and property safety.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 2 and Figure 3 An embodiment of this utility model is provided: a passive cooling outdoor power cabinet, including a base 1, a cabinet 2 is mounted on the top of the base 1, a top cover 5 is mounted on the top of the cabinet 2, a rainproof auxiliary component 18 is provided between the cabinet 2 and the top cover 5, a passive heat dissipation component 10 is provided inside the cabinet 2, and a power distribution box 6 is mounted inside the cabinet 2.

[0034] The passive heat dissipation component 10 includes an aluminum base 12, which is assembled with the distribution box 6. A heat dissipation pipe 13 is mounted on the side of the aluminum base 12 away from the distribution box 6. Multiple heat dissipation fins 14 are evenly distributed around the outer periphery of the heat dissipation pipe 13. The aluminum base 12 is tightly connected to the distribution box 6, which greatly improves the efficiency and accuracy of heat transfer. When the electrical equipment inside the distribution box 6 inevitably generates heat during operation, the aluminum base 12 can sense and absorb this heat. The heat dissipation pipe 13 is firmly mounted on the side of the aluminum base 12 away from the distribution box 6, and multiple heat dissipation fins 14 are evenly distributed around the outer periphery of the heat dissipation pipe 13. These heat sinks 14 not only increase the surface area in contact with the air, but also have good thermal conductivity. When heat is conducted from the aluminum base 12 to the heat dissipation pipe 13, the heat dissipation pipe 13 quickly disperses the heat to each heat sink 14. With the help of the principle of natural convection, the surrounding air exchanges heat with the heat sinks 14, so that the heat can be stably and continuously dissipated into the surrounding air, thereby effectively realizing the function of passive heat dissipation. This creates a relatively cool and stable operating environment for the electrical equipment in the distribution box 6, while effectively reducing the investment cost of active cooling, thereby ensuring the stable heat dissipation and normal operation of the outdoor power cabinet in the outdoor environment.

[0035] Reference Figure 1 and Figure 4The rainproof auxiliary component 18 includes a rainproof plate 19, which is fixedly connected to the top of the housing 2. A groove 22 is formed on the side of the rainproof plate 19 away from the housing 2. A drainage plate 21 is fitted in the middle of the rainproof plate 19, and a through groove 20 is formed on the side of the rainproof plate 19 near the drainage plate 21. The drainage plate 21 is positioned directly above the heat sink 14. In the rainproof auxiliary component 18, the rainproof plate 19, as a key component, plays a crucial role in blocking rainwater. The through groove 20 on the rainproof plate 19 and the fitted drainage plate 21 work together to form a rainwater drainage system. When rainfall occurs, the rainwater... The water is first blocked by the rainproof plate 19, and then guided by the channel 20, it flows to the diversion plate 21 along a specific and reasonable path. The diversion plate 21 further guides and disperses the rainwater, effectively preventing the rainwater from accumulating on the top of the box 2, thereby avoiding the risk of leakage due to excessive water accumulation. At the same time, some rainwater can fall accurately onto the heat sink 14 under the guidance of the diversion plate 21. Since the rainwater has a low temperature, it can quickly absorb the heat on the heat sink 14 when it comes into contact with the heat sink 14, and then carry away the heat through its own evaporation, thereby improving the heat dissipation efficiency of the heat sink 14.

[0036] This method not only utilizes rainwater resources but also ensures the normal performance of heat dissipation components from multiple aspects, ensuring that the power equipment is not affected by rainwater and remains in a stable operating state. It effectively guarantees that outdoor power cabinets can continuously and stably dissipate heat in complex and ever-changing outdoor environments and maintain the normal operation of power equipment, laying a solid foundation for the reliability and security of power supply.

[0037] Reference Figure 1 and Figure 2The outer shell 11 is fixedly connected to the outside of the enclosure 2. The heat dissipation pipe 13 and heat sink 14 are both located inside the outer shell 11. The outer side of the enclosure 2 is equipped with a door 3. A protective seat 15 is fixedly connected to the side of the enclosure 2 away from the distribution box 6. An air inlet 16 is provided inside the protective seat 15. An air outlet 17 is opened in the middle of the enclosure 2. A rainproof plate 19 is installed between the top cover 5 and the enclosure 2. A control module 7 is provided on the side of the distribution box 6 near the door 3. A handle 4 is fixedly connected to the side of the door 3 away from the enclosure 2. An input port 8 and an output port 9 are provided on the side of the enclosure 2 away from the door 3. The input port 8 is connected to the output port 9 through the distribution box 6. The layout of the air outlet 17 fully considers the characteristics of airflow and heat dissipation requirements inside the enclosure, so that hot air can exchange heat with the heat dissipation components. Afterwards, it can smoothly and efficiently exhaust the air from the box 2, thereby maintaining the continuous renewal of air and effective heat dissipation inside the box 2. On the side of the distribution box 6 near the door 3, a control module 7 is scientifically and rationally set up. As the core control unit of the distribution box 6, the control module 7 can accurately monitor and adjust the power distribution and equipment operation status inside the distribution box 6. On the side of the door 3 away from the box 2, a handle 4 is firmly fixedly connected. The handle 4 facilitates opening and closing the door 3. The input port 8 is closely connected to the output port 9 through the internal circuit connection system of the distribution box 6, forming a complete and efficient power transmission link. It can reasonably distribute and convert the externally input electrical energy and stably output it to the corresponding electrical equipment or power network, ensuring the safety, reliability and efficiency of the entire power supply process.

[0038] Working principle: The electrical equipment in the distribution box 6 generates heat during operation. This heat is absorbed by the aluminum base 12, which then conducts the heat to the heat dissipation pipe 13. The heat dissipation fins 14 on the outer periphery of the heat dissipation pipe 13, with their large surface area, allow heat to dissipate to the surrounding air through natural convection, achieving initial heat dissipation. Simultaneously, the air inlet 16 of the protective base 15 connects to the outside, allowing cold air from the outside to enter the box 2. Due to the difference in density between hot and cold air, the cold air causes the hot air inside the box to rise, forming a natural air circulation. The air is finally discharged from the enclosure 2 through the air outlet 17, achieving effective heat removal and cooling. The rainproof plate 19 in the rainproof auxiliary component 18 serves to block rainwater. The through groove 20 opened in the rainproof plate 19 and the assembled diversion plate 21 work together to guide the rainwater to flow along a specific path, preventing rainwater from accumulating on the top of the enclosure 2 or flowing into the enclosure. At the same time, the rainwater falls into the heat sink 14 to improve the heat dissipation function and avoid affecting the performance of the heat dissipation component and the operation of the power equipment, thereby ensuring the stable heat dissipation and normal operation of the outdoor power cabinet in the outdoor environment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
