Description

[0002] A system integrated control cabinet is a device that integrates multiple functions into one unit for centralized management and control of electrical equipment and systems. Through structured cabling systems and computer network technology, it integrates various separate devices, functions, and information into an interconnected, unified, and coordinated system to achieve centralized, efficient, and convenient management. System integrated control cabinets have wide applications in industrial automation and power systems. In industrial automation, they serve as a bridge between centralized control equipment and field devices, and are used in industries such as machinery, manufacturing, energy, chemicals, and light industry. In power systems, they are a crucial component of electrical equipment and are widely used in power transmission and distribution, power generation, and substation.

[0003] The system integrated control cabinet contains several control circuits. As the system becomes more complex, the number of integrated control circuits in the cabinet increases, generating more and more heat. Traditional system integrated control cabinets only use simple exhaust fans to cool the inside of the cabinet. This method has limited heat exchange efficiency and cannot achieve rapid cooling, thus affecting the lifespan of electrical components and resulting in poor performance.

[0004] Therefore, we propose a heat-dissipating system integrated control cabinet to solve the above problems. Utility Model Content

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.

[0026] Example

[0027] like Figures 1-4As shown in the figure, an embodiment of the present invention proposes a heat-dissipating system integrated control cabinet, including a cabinet body 1. A cabinet door 2 is installed on the front side of the cabinet body 1 via a hinge. The cabinet body 1 has an air inlet chamber 3, an equipment installation chamber 4, and an air outlet chamber 5 arranged sequentially from bottom to top. Louvers 6 are installed on both sides of the air inlet chamber 3, and pipe interfaces 7 are distributed on the inner top of the air inlet chamber 3. The upper part of the pipe interface 7 is connected to the equipment installation chamber 4, and a Venturi duct 8 is installed on its lower part. An electrical component backplate 9 and a temperature sensor 10 are respectively installed in the equipment installation chamber 4. An auxiliary heat dissipation groove 11 is provided on the rear side of the electrical component backplate 9. An aluminum extruded heat sink 12 is installed in the auxiliary heat dissipation groove 11, and a cooling fan 13 is installed on the aluminum extruded heat sink 12. The inner top of the equipment installation chamber 4 is... The air outlet chamber 5 is equipped with an opening 14. A centrifugal fan 15 is installed inside the air outlet chamber 5, and the air inlet end of the centrifugal fan 15 is connected to the opening 14. A vertical layered design is adopted to form a layered airflow channel. The louvers 6 and venturi ducts 8 of the air inlet chamber 3 work together to efficiently draw in external cold air. The venturi ducts 8 can accelerate the airflow and increase the air intake. The auxiliary heat dissipation slots 11 on the back side of the electrical component backplate 9 in the equipment installation chamber 4 are equipped with aluminum extruded heat sinks 12 and cooling fans 13. The aluminum extruded heat sinks 12 increase the heat dissipation area, and the cooling fans 13 accelerate the heat dissipation. The centrifugal fan 15 of the air outlet chamber 5 is used to exhaust the hot air in the equipment installation chamber 4 to the outside. The whole structure forms a complete heat dissipation path from bottom to top, which greatly improves the heat dissipation efficiency. Air outlets 16 are provided on both sides of the air outlet chamber 5.

[0028] like Figure 1 As shown, in some embodiments, a thermostat 17 is embedded in the cabinet door 2. The temperature sensor 10, the cooling fan 13, and the centrifugal fan 15 are all electrically connected to the thermostat 17. The temperature sensor 10 monitors the temperature inside the cabinet in real time. The thermostat 17 automatically controls the operating status of the cooling fan 13 and the centrifugal fan 15 according to the temperature. When the temperature is low, the speed can be reduced or the operation can be stopped to reduce energy consumption. When the temperature rises, the speed can be increased to enhance heat dissipation, thus realizing intelligent and energy-saving heat dissipation control.

[0029] like Figure 1 As shown, in some embodiments, a sealing gasket 18 is attached to the inner surface of the cabinet door 2, and the sealing gasket 18 is tightly attached to the cabinet body 1. The sealing gasket 18 improves the sealing performance of the cabinet body 1 and prevents dust and other contaminants from entering.

[0030] like Figure 2 As shown, in some embodiments, a flat lock 19 is installed on the cabinet door 2 and is locked to the cabinet body 1 through the flat lock 19.

The filter screens 21 are inserted into the slots 20, which makes them easy to disassemble and replace, and facilitates daily maintenance.

[0032] like Figure 3 As shown, in some embodiments, the filter screen 21 corresponds to the position of the louver 6, which is located below the Venturi duct 8. The filter screen 21 can filter dust and impurities in the air, ensuring that the air entering the cabinet is clean, providing a good operating environment for electrical components, and reducing the occurrence of failures.

The aluminum extrusion heat sink 12 increases the heat dissipation area, and the cooling fan 13 accelerates the heat dissipation. The ventilation holes 22 on the upper and lower sides of the auxiliary heat dissipation groove 11 correspond to the vertical convection groove of the aluminum extrusion heat sink 12, forming a vertical airflow, which is conducive to heat dissipation.

The heat dissipation hole 23 on the rear side of the equipment installation chamber 4 corresponds to the air outlet of the cooling fan 13, which facilitates the exhaust of heat from the rear side of the cabinet 1 through the cooling fan 13.

[0035] In use, a vertical layered design is adopted to form layered airflow channels. The louvers 6 and Venturi ducts 8 of the air inlet chamber 3 work together to efficiently draw in external cold air. The Venturi ducts 8 can accelerate airflow and increase the air volume. The auxiliary heat dissipation slots 11 behind the electrical component backplate 9 (metal material) in the equipment installation chamber 4 are equipped with aluminum extruded heat sinks 12 and cooling fans 13. The aluminum extruded heat sinks 12 increase the heat dissipation area, and the cooling fans 13 accelerate the dissipation of heat. The centrifugal fan 15 of the air outlet chamber 5 is used to exhaust the hot air in the equipment installation chamber 4 to the outside. The whole process forms a complete heat dissipation path from bottom to top, which greatly improves the heat dissipation efficiency.

[0036] In summary, a vertically layered design is adopted to form layered airflow channels. The louvers 6 and Venturi ducts 8 of the air inlet chamber 3 work together to efficiently draw in external cold air. The Venturi ducts 8 can accelerate airflow and increase the air volume. The auxiliary heat dissipation slots 11 on the back side of the electrical component backplate 9 in the equipment installation chamber 4 are equipped with aluminum extruded heat sinks 12 and cooling fans 13.
