Description

Technical Field

[0002] With the widespread application of microgrids, 10-parallel microgrid cabinets, as the core equipment integration carriers, have densely packed internal components that generate significant heat during operation. Traditional cabinet cooling methods, such as simple fan cooling, struggle to maintain a stable and suitable temperature environment when facing high loads and long-term operation of microgrid equipment. Excessive temperatures can lead to performance degradation and even malfunctions in critical equipment such as inverters and power distribution units, severely impacting the stability and reliability of microgrid operation. Simultaneously, humidity control within the cabinet is crucial; excessive humidity can cause corrosion and short circuits in electrical components. Furthermore, in special environments, such as high-temperature, high-humidity, or dusty industrial scenarios, ordinary cooling and environmental control methods are even more inadequate. Therefore, developing a 10-parallel microgrid cabinet that incorporates an efficient industrial air conditioning solution is urgently needed. Utility Model Content

[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to Figure 1-5 As shown, a microgrid 10 parallel cabinet includes an integrated photovoltaic incoming line cabinet 1, a dual power supply cabinet 2, and a grid-connected cabinet 3. The grid-connected cabinet 3 is provided with a door 4, and an industrial air conditioner is embedded in the door 4 after it is opened.

[0022] The photovoltaic incoming line cabinet 1 is equipped with several first copper busbars 5 to form a photovoltaic power generation incoming line circuit;

[0023] The dual power supply cabinet 2 is provided with a second copper busbar 6 for connecting the generator input line, and the second copper busbar 6 is connected to a third copper busbar 8 for outputting to the load through a circuit breaker 7.

[0024] Industrial air conditioning integrated structure:

[0025] Overall Layout: A dedicated installation area for industrial air conditioning is reserved on the side or back of the cabinet. This area is separated from the internal equipment space of the cabinet by a sealed partition, but is equipped with ventilation ducts and return air channels to achieve air circulation between the air conditioner and the internal air of the cabinet. The industrial air conditioner adopts an embedded installation method, and its air outlet is connected to the concentrated area of ​​equipment inside the cabinet through ventilation ducts, ensuring that cool air can be accurately delivered to the vicinity of equipment with high heat generation.

[0026] Ventilation duct design: The ventilation ducts are made of flame-retardant, insulating materials with good thermal conductivity, such as aluminum alloy. Inside the ducts are guide vanes that can adjust the direction and speed of cool airflow according to equipment layout and heat dissipation requirements, ensuring even cooling coverage of all equipment. Return air ducts are located at the bottom or top of the cabinet, guiding heated air from inside the cabinet back to the industrial air conditioner for cooling, forming a complete air circulation system.

[0027] Precise temperature and humidity control system:

[0028] Sensor Placement: Temperature and humidity sensors are evenly distributed in multiple key locations inside the cabinet, such as near the inverter, seamless switching module, and power distribution unit. These sensors can collect real-time temperature and humidity data around the equipment and transmit the data to the central control system.

[0029] Intelligent Control Algorithm: The central control system employs an advanced intelligent control algorithm. Based on temperature and humidity data fed back from sensors and preset temperature and humidity thresholds, it automatically adjusts the cooling, heating, and dehumidifying functions of the industrial air conditioner. When the temperature exceeds the set upper limit, the industrial air conditioner increases its cooling power; when the temperature falls below the set lower limit, the heating function is activated; and when the humidity exceeds the appropriate range, the dehumidification mode is turned on. Simultaneously, the system can dynamically adjust the temperature and humidity control strategy based on the operating status and load changes of the equipment within the cabinet, achieving precise environmental control.

[0030] Air purification and dust removal functions:

[0031] Air purification module: An air purification module is integrated at the air inlet of the industrial air conditioner. This module adopts a multi-layer filtration structure, including a pre-filter, a medium-efficiency filter, and a high-efficiency filter. The pre-filter can filter out larger dust and impurities in the air; the medium-efficiency filter further intercepts smaller particulate pollutants; the high-efficiency filter can remove fine dust, smoke, and harmful gases from the air, ensuring that the air cleanliness entering the cabinet meets the equipment operating requirements.

[0032] Dustproof design: In addition to the air purification module, all openings in the cabinet, such as door gaps and vents, are protected by both sealing strips and dust filters. The sealing strips effectively prevent dust from entering the cabinet through gaps, while the dust filters provide secondary filtration of the air entering the cabinet, further enhancing the dustproof effect and providing a clean environment for equipment operation.

[0033] Collaborative working mechanism between air conditioning system and server rack equipment:

[0034] Interlocking Control: The industrial air conditioning system is interconnected with the energy management unit and monitoring module within the cabinet. When the energy management unit detects an increase in microgrid load and increased heat generation from the equipment, it promptly sends a signal to the industrial air conditioning system, which automatically increases its cooling capacity to meet the equipment's heat dissipation needs. Simultaneously, the monitoring module monitors the real-time operating status of the industrial air conditioning system and environmental parameters within the cabinet, providing this information to operators for timely understanding of the system's operational status.

[0035] Fault Diagnosis and Emergency Handling: The system possesses comprehensive fault diagnosis capabilities. When the industrial air conditioner malfunctions or the temperature and humidity sensor malfunctions, the monitoring module can quickly detect the fault information and issue an alarm. Simultaneously, the system automatically activates emergency cooling measures, such as increasing the speed of the exhaust fan at the top of the cabinet and turning on the backup cooling fan, to ensure that the equipment inside the cabinet continues to operate within an acceptable temperature range until the fault is repaired, thus guaranteeing the normal operation of the microgrid.

[0036] In this embodiment, the grid-connected cabinet 3 is equipped with a ventilation duct that is connected to the industrial air conditioner for air circulation, and the ventilation duct is equipped with guide vanes.

[0037] In this embodiment, the photovoltaic incoming line cabinet 1 and the dual power supply cabinet 2 are equipped with multiple temperature sensors.

[0038] In this embodiment, both the dual power supply cabinet 2 and the grid-connected cabinet 3 are equipped with a secondary chamber 9 at their upper ends to achieve isolation between the primary circuit and the secondary circuit.

[0039] In this embodiment, the grid-connected cabinet 3 is also equipped with a fan 10 to further improve the heat dissipation effect.

[0040] This application has the following beneficial effects:

[0041] Superior heat dissipation and environmental control performance: By integrating an industrial air conditioning system, precise control of temperature and humidity inside the cabinet is achieved, ensuring that the equipment is always in the optimal operating environment, effectively reducing the probability of equipment failure due to overheating or excessive humidity, and improving the stability and reliability of microgrid operation.

[0042] Strong environmental adaptability: Air purification and dustproof functions enable the cabinet to adapt to various complex environments, such as industrial production sites and dusty outdoor environments, reducing the corrosion of equipment by dust and pollutants and extending the service life of the equipment.

[0043] Highly efficient collaborative operation capability: The air conditioning system and other equipment in the cabinet are linked for control, which enables automatic adjustment of heat dissipation strategy according to the microgrid's operating status, improving energy utilization efficiency and simplifying system management and maintenance.

[0044] A robust fault protection mechanism: Fault diagnosis and emergency handling functions provide additional protection for microgrid operation. When the air conditioning system fails, emergency measures can be quickly activated to avoid equipment damage and microgrid operation interruption due to environmental malfunction, thereby improving the system's fault tolerance.

[0045] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
