Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air conditioning engineering, in particular to a flexible air supply and return device for a transmission cabinet. Background Art
[0002] At present, the air conditioning system of the transmission room generally adopts the precision air conditioning upward air supply method, and the transmission cabinets arranged in the transmission room are usually designed with front air intake and top air outlet. The heat dissipation method of the transmission cabinet and the airflow of the upward air supply air conditioning system are in conflict, resulting in low heat dissipation efficiency. As a result, the traditional precision air conditioning with upward air supply cannot effectively meet the high power consumption and unique heat dissipation requirements of the equipment inside the transmission cabinet. This not only affects the performance and life of the equipment, but may also cause safety problems such as overheating of the equipment inside the transmission cabinet.
[0003] Therefore, to address the heat dissipation problem, existing solutions often rely on lowering the air conditioning temperature or increasing the number of air conditioners. Although this method can alleviate the heat island effect in the short term, it causes huge energy waste in the long run and is not in line with today's society's pursuit of energy conservation and emission reduction. In addition, this approach may also lead to excessive burden on the air conditioning system, shorten its service life, and increase maintenance costs.
[0004] Furthermore, the equipment in the transmission room draws high power, and local hotspots easily form within each transmission cabinet, disrupting internal airflow. This turbulence not only causes the mixing of hot and cold airflows, reducing cooling efficiency, but can also lead to uneven temperature distribution within the room, impacting the stable operation of the equipment. Therefore, existing transmission room air conditioning systems are significantly inadequate in meeting the cooling needs of high-power equipment and are in urgent need of improvement. Utility Model Content
[0005] The utility model solves the deficiencies of the prior art and provides a transmission cabinet flexible air supply and return device which ensures that equipment operates at an optimal temperature and improves energy utilization efficiency.
[0006] To achieve the above-mentioned purpose, the utility model first proposes a flexible air supply and return device for a transmission cabinet, including a transmission cabinet, wherein the front side of the transmission cabinet is provided with a main air inlet and a main air outlet, the front side of the transmission cabinet is hinged with a cabinet door frame, and the inner sides of the two side frames of the cabinet door frame are fixed with adjustment brackets arranged in the vertical direction, and multiple installation gears are arranged in the height direction on the two adjustment brackets. The installation gears of the adjustment brackets are detachably installed with an air supply module and an exhaust module, the air supply module corresponds to the main air inlet position of the transmission cabinet, and the exhaust module corresponds to the main air outlet position of the transmission cabinet.
[0007] In this embodiment, multiple groups of first screw holes are symmetrically arranged along the height direction on the two adjustment brackets to form multiple installation positions, and the two sides of the air supply module and the air exhaust module are respectively fixed in the first screw holes of the two adjustment brackets by bolts.
[0008] In this embodiment, the air supply module includes a small air-conditioning radiator and an air supply fan. The air supply fan is fixed on the fins of the small air-conditioning radiator. Second screw holes matching the first screw holes on the adjustment bracket are provided on both sides of the small air-conditioning radiator. The small air-conditioning radiator is provided with a refrigerant inlet and a refrigerant outlet. The refrigerant inlet and the refrigerant outlet of the small air-conditioning radiator are connected to the air-conditioning outdoor unit through pipes.
[0009] In this embodiment, the air supply fan is an axial flow fan that can be adjusted forward and reverse.
[0010] In this embodiment, the exhaust module includes a mounting plate and an exhaust fan. The mounting plate is provided with ventilation holes, and the exhaust fan is installed in the ventilation holes of the mounting plate. Third screw holes matching the first screw holes on the adjustment bracket are provided on both sides of the mounting plate.
[0011] In this embodiment, the exhaust fan is an axial flow fan that can be adjusted forward and reverse.
[0012] With the above structure, the utility model has the following advantages:
[0013] 1. Since the positions of the total air inlet and total air outlet of different transmission equipment in the transmission cabinet are not the same, the device is provided with an adjustment bracket on the door frame of the cabinet. By adjusting the installation gear set on the bracket, the position of the air supply module and the exhaust module can be adjusted in the height direction, so that the air supply module and the exhaust module correspond to the total air inlet and total air outlet of the transmission cabinet respectively. In this way, the air intake direction of the air supply module is consistent with the air suction direction of the transmission equipment, and the air exhaust direction of the exhaust module is consistent with the air outlet direction of the transmission equipment, so that the air flow direction in the cabinet is consistent, which solves the problem of disordered air flow organization in the cabinet, avoids local hot spots, and reduces the waste of cooling capacity.
[0014] 2. Both the air supply fan and the exhaust fan of this device adopt axial flow fans that can be adjusted in both positive and negative directions to reduce fan noise. At the same time, through reversing, they can meet the different deployment requirements of different manufacturers.
[0015] 3. The air supply module of this device includes a small air-conditioning radiator to ensure that the cooling capacity is accurately released into the transmission cabinet.
[0016] In summary, this device can improve the efficiency of the cooling system by optimizing the direction of airflow and reducing airflow turbulence. The axial flow fan helps to reduce operating noise and improve the working environment. By reducing local hot spots and cooling waste, it can reduce overall energy consumption. Overall, this device's air conditioning, refrigeration and ventilation system designed for the interior of the cabinet helps ensure that key equipment operates at the optimal temperature while improving energy efficiency.
