Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, in particular to an embedded installed power distribution cabinet. Background Art

[0002] Traditional distribution cabinet installation methods are mainly divided into two categories: wall-mounted installation and embedded installation.

[0003] Wall-mounted installation: This installation method is to hang the cabinet directly on the wall and connect it to the wall through screws or other fixings. The advantage of wall-mounted installation is that the installation is relatively simple and quick, does not require complex structural modifications, and is suitable for most wall surfaces. However, the cabinet of wall-mounted installation usually protrudes from the wall and occupies a certain amount of indoor space. For a small space environment, it may appear crowded, affecting the appearance and efficiency of use.

[0004] Embedded installation: Embedded installation is to hide part or all of the cabinet inside the wall, leaving only the cabinet door or part of the front exposed. This installation method can maximize the use of space, reduce the occupation of indoor space, and make the indoor environment look neater. However, simple embedded installation often ignores the heat dissipation problem inside the cabinet. Due to the small space between the cabinet and the wall, the air circulation is limited, and the heat generated by the operation of the equipment is difficult to dissipate effectively. Long-term operation may cause the equipment to overheat, affecting the life and stability of the equipment. Utility Model Content

[0005] The main purpose of the utility model is to provide an embedded power distribution cabinet to solve the problems in the above-mentioned background technology.

[0011] Preferably, a plurality of transverse plates are fixedly provided in the inner cabinet for mounting components.

[0012] Preferably, a wire inlet is provided at the bottom of the outer cabinet for threading and connection.

[0013] The utility model provides an embedded power distribution cabinet, which has the following beneficial effects:

[0014] 1. Embedded installation is adopted to embed most of the cabinet structure into the wall, which significantly reduces the occupation of indoor space and is particularly suitable for environments with limited space.

[0015] 2. The exhaust cavity and air intake cavity formed between the inner cabinet and the outer cabinet, as well as the built-in air intake fan and exhaust fan, together build an efficient heat convection circulation system, which significantly improves the heat dissipation efficiency and avoids performance degradation or damage caused by overheating of the equipment.

DETAILED DESCRIPTION

[0021] like Figure 1~2 As shown, an embedded power distribution cabinet includes a cabinet 1 embedded in a wall, an inner cabinet 101 is arranged inside an outer cabinet 102 in the cabinet 1, two sides of the inner cabinet 101 are fixedly connected to the outer cabinet 102, an exhaust cavity 107 is arranged between the top of the inner cabinet 101 and the outer cabinet 102, and an air intake cavity 106 is arranged between the bottom of the inner cabinet 101 and the outer cabinet 102;

[0022] An intake fan 8 and an exhaust fan 7 are arranged in the intake cavity 106 and the exhaust cavity 107. A filter layer 6 is arranged on one side of the intake fan 8, and the filter layer 6 is fixed in the intake cavity 106. A slot is provided at the installation position on the wall, and the cabinet 1 is embedded therein. The cabinet 1 includes an outer cabinet 102 and an inner cabinet 101. An exhaust cavity 107 and an intake cavity 106 are formed between the outer cabinet 102 and the inner cabinet 101 for air circulation and heat dissipation. The intake fan 8 and the exhaust fan 7 can speed up the air flow, and the filter layer 6 can filter dust to prevent dust from entering the cabinet 1 and contaminating components.

[0023] The cabinet is divided into two layers, the outer cabinet 102 is fixed to the wall, and the inner cabinet 101 is located inside it, and the gap formed between the two is designed as an exhaust cavity 107 and an air intake cavity 106. Such a double-layer structure can provide additional protection and allow air to circulate between the inner and outer cabinets, thereby helping to cool the equipment.

[0024] The air intake fan 8 and the exhaust fan 7 are respectively located in the air intake cavity 106 and the exhaust cavity 107, which can promote the rapid circulation of air, effectively remove the heat generated by the equipment in the cabinet, and prevent overheating. The air sucked by the air intake fan 8 first passes through the filter layer 6, which can prevent external dust and other particles from entering the cabinet, keep the electrical components clean, and reduce the failure rate.

[0025] The cabinet 1 is embedded and installed by slots pre-opened on the wall. This method is not only beautiful, but also reduces the occupation of indoor space, and is suitable for application scenarios with limited space or requiring a clean environment, such as residential, office or commercial buildings.

[0026] Preferably, a plurality of ear plates 5 are fixedly provided on both sides of the cabinet 1, and the ear plates 5 are fixed to the wall by bolts. Expansion bolts are driven into holes on both sides of the slotted hole in the wall, and the ear plates 5 are locked on the expansion bolts by nuts, thereby achieving fixed installation.

[0027] Mark the position where the slot hole needs to be opened on the wall, and ensure that the size of the slot hole matches the cabinet 1. At the same time, mark the fixing points of the ear plate 5 on both sides of the slot hole to facilitate the subsequent installation of expansion bolts.

[0028] Use appropriate tools to open slots in the wall and drill holes at the previously marked fixing points. The diameter of the drilled holes should be slightly smaller than the diameter of the expansion bolts so that the expansion bolts can be tightly fixed in the holes.

[0029] Drive the expansion bolt into the pre-drilled hole. One end of the expansion bolt has an expansion sleeve, which expands in the hole when the bolt is tightened, providing a strong grip.

[0030] Align the ear plate 5 of the cabinet 1 with the expansion bolt, and then lock the ear plate 5 on the expansion bolt with the nut. Make sure that each ear plate is evenly stressed and the cabinet is stable and does not shake.

[0031] After installation, check that the cabinet is secure, all bolts and nuts are fully tightened, and that the cabinet is level.

[0032] Preferably, a hinged cabinet door 2 is provided on the outside of the cabinet body 1, and an upper exhaust grille 3 and a lower air intake grille 4 are provided at both ends of the cabinet door 2. The upper exhaust grille 3 and the lower air intake grille 4 are respectively arranged at the ends of the exhaust cavity 107 and the air intake cavity 106.

[0033] The upper exhaust grille 3 is located at the upper end of the cabinet door 2 and is connected to the exhaust cavity 107. Its function is to allow the hot air inside the cabinet to be discharged through it, effectively reducing the temperature inside the cabinet and preventing electrical equipment from being damaged due to overheating.

[0034] The lower air intake grille 4 is located at the lower end of the cabinet door 2 and is connected to the air intake cavity 106. Its main function is to allow fresh, cooler air to enter the cabinet to help cool the internal equipment. The air intake fan 8 will accelerate this process and improve the air exchange efficiency.

[0035] This design utilizes the natural principle that hot air rises, forming an effective heat convection cycle. Hot air is exhausted from the top and cold air enters from the bottom, which helps maintain the temperature inside the cabinet within a suitable range, extending the service life of the equipment and improving its operating efficiency.

[0036] In addition, the exhaust grille and the air intake grille on the cabinet door 2 are usually designed to be a mesh structure that can block larger particles to reduce the entry of dust and foreign matter, but will not significantly affect the air circulation. This ensures the heat dissipation performance and increases the dustproof ability of the equipment.

[0037] Preferably, a baffle 103 is fixedly disposed in the outer cabinet 102, and the baffle 103 is disposed in the middle of the inner cabinet 101. The baffle 103 can change the air circulation direction so that cold air enters the inner cabinet 101 to take away heat.

[0038] The baffle 103 can guide the cold air in the air inlet cavity 106 to flow more effectively to the key areas of the inner cabinet 101, ensuring that the air flows through the equipment that needs to be cooled. Through reasonable layout, the baffle can help the air to be distributed more evenly to avoid local overheating.

[0039] Under the guidance of the baffle 103, the cold air can directly contact the heat-generating electronic components to improve the heat exchange efficiency. The hot air is guided to the exhaust chamber 107 and drawn out by the exhaust fan 7, forming an efficient heat convection cycle.

[0040] The baffle 103 can also play a certain degree of air flow isolation role, prevent air mixing between different areas, ensure that hot air does not recirculate into the air intake path, thereby preventing the hot air from being sucked back into the inner cabinet 101, and improving the heat dissipation effect.

[0041] In addition to thermal management, the baffle 103 may also provide additional structural support and enhance the overall rigidity of the cabinet, especially when the inner cabinet 101 is long or contains heavy equipment.

[0042] By controlling the airflow path, the baffle 103 can also help reduce the noise generated by the fan and improve the working environment.

[0043] Preferably, a plurality of transverse plates 105 are fixedly provided in the inner cabinet 101 for mounting components. The transverse plates are designed with a plurality of mounting holes, allowing technicians to adjust the positions of components as needed to adapt to different circuit layouts or facilitate maintenance.

[0044] The transverse plates 105 help to disperse the hot air because they can act as a heat conduction medium to transfer the heat generated by the components to other parts of the cabinet, and finally exhaust it through the exhaust cavity 107 and the exhaust fan 7.

[0045] Proper insulation between the cross plates 105 and between the cross plates 105 and the cabinet body can provide necessary electrical isolation, reduce the risk of short circuit, and improve the safety of the system.

[0046] By arranging components in an orderly manner on the horizontal board 105 , line management can be simplified, cable routing can be made clearer, and troubleshooting and system upgrades can be facilitated.

[0047] The use of the transverse plate 105 makes the internal layout of the power distribution cabinet more modular, which is convenient for standardized production and future expansion or modification.

[0048] The cross plate 105 needs to have sufficient load-bearing capacity to support the weight of the components mounted thereon while maintaining the stability and integrity of the structure.

[0049] Preferably, a cable inlet 104 is provided at the bottom of the outer cabinet 102 for threading and connecting cables. The cable inlet 104 provides a passage for cables to enter the cabinet, so that external power supply or communication lines can be safely connected to the equipment in the power distribution cabinet.

[0050] The inlet 104 is provided with a sealing ring or a sealing gasket to ensure waterproof, dustproof and insect-proof effects, which can protect the electrical equipment inside the cabinet from the influence of the external environment and improve the reliability of the system.

[0051] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
