Description

Technical Field

[0001] This utility model relates to the field of aircraft ground air conditioning, and more specifically, to an aircraft ground air conditioning unit with no heat recirculation. Background Technology

[0002] Key tasks related to civil aviation include accelerating the "oil-to-electricity" conversion of airport facilities and vigorously promoting the special project of aircraft shore-based power supply (i.e., replacement of aircraft auxiliary power units, hereinafter referred to as APU replacement). The target indicators are: after three years of efforts, the level of electrification of airport operations will be significantly improved, noise and emissions within the airport will be reduced in tandem, and air quality and working environment within the airport will be significantly improved. Under the premise of meeting the technical standards and relevant management regulations for civil aviation airport equipment, appropriate technical paths and products will be selected to ensure the smooth replacement of special vehicles within the airport and the safety of construction without interrupting operations. The use of new energy equipment and vehicles will be promoted, and the replacement of aircraft APUs with ground air conditioning equipment (air conditioning units) will be promoted. Aircraft will mainly use APU replacement facilities when parked at airport boarding bridges and remote stands. The application of new technologies will be actively promoted. Airports should work with resident units and research units to carry out the construction of a monitoring system for the operation and energy consumption of new energy vehicles and APU replacement facilities, and actively and steadily carry out the construction of intelligent charging facilities, energy storage facilities, microgrid facilities, etc. as a guiding direction.

[0003] Existing aircraft ground air conditioning units suffer from heat recirculation during operation, where some of the cooled or heated air is remixed into the intake airflow. This reduces the cooling or heating efficiency of the air conditioning unit and increases energy consumption, which not only affects the performance of the aircraft ground air conditioning unit but also increases operating costs.

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a heat-free aircraft ground air conditioning unit that can achieve heat-free recirculation during the cooling process.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A heat-free recirculation aircraft ground air conditioning unit includes a main body, on which condenser radiators are fixedly installed on both sides, a top plate is installed on the top of the main body, a heat dissipation mechanism is provided at the bottom of the top plate, and a protective mechanism is provided at the top of the top plate relative to the heat dissipation mechanism.

[0009] Furthermore, the heat dissipation mechanism includes a heat dissipation groove formed on the top of the top plate, and an annular cylinder welded to the bottom of the top plate relative to the heat dissipation groove, with a cooling fan installed inside the annular cylinder.

[0010] Furthermore, a first protective net is provided on the top of the cooling fan blades, and the fixing member is fixedly connected to the top of the top plate.

[0011] Furthermore, a connector is fixedly connected to the bottom of the top plate, and a second protective net is provided at the bottom of the cooling fan blades. The second protective net and the connector are fixedly connected.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution installs condenser radiators at the rear and both sides of the main body. The negative pressure of the cooling fan makes the ambient air enter through the condenser radiator to dissipate heat from the high-pressure refrigerant in the condenser radiator. The air is then discharged from the top cooling fan and blown into the air. There is no hot air backflow. The overall system adopts a side air intake and top exhaust method, which can ensure the heat dissipation effect, make the heat dissipation uniform, and prevent hot air backflow, making it more efficient.

[0018] (2) This solution utilizes the first and second protective nets to protect the cooling fan, the fixing parts to install the cooling fan, and the protective mechanism to prevent rain, thereby increasing the safety of the main body. Attached Figure Description

[0033] Example 1:

[0034] Please see Figure 1-6 A heat-recirculation-free aircraft ground air conditioning unit includes a main body 1. Condensers 2 are fixedly installed on the sides of the main body 1. An air intake mesh is installed on the surface of the main body 1, with the condensers 2 installed inside the air intake mesh. A top plate 3 is installed on the top of the main body 1, and a heat dissipation mechanism 4 is provided at the bottom of the top plate 3. A protective mechanism 5 is provided at the top of the top plate 3 relative to the heat dissipation mechanism 4. By installing condensers 2 on the rear and both sides of the main body 1, and by setting the heat dissipation mechanism 4, the overall unit adopts a side-intake and top-exhaust airflow method, ensuring heat dissipation effect, uniform heat dissipation, no hot air recirculation, and higher efficiency. The protective mechanism 5 provides rain protection.

[0035] The heat dissipation mechanism 4 includes a heat dissipation groove 41 on the top of the top plate 3. An annular cylinder 42 is welded to the bottom of the top plate 3 at a position relative to the heat dissipation groove 41. A cooling fan 43 is installed inside the annular cylinder 42. The cooling fan 43 can be installed by setting the heat dissipation groove 41 and the annular cylinder 42. A first protective net 44 is set on the top of the fan blades of the cooling fan 43. A fixing member 45 is fixedly sleeved on the top of the cooling fan 43. The fixing member 45 is fixedly connected to the top of the top plate 3. By setting the first protective net 44, external debris can be prevented from affecting the cooling fan 43. By setting the fixing member 45, it is convenient to install the cooling fan 43.

[0036] Furthermore, a connector 46 is fixedly connected to the bottom of the top plate 3, and a second protective net 47 is provided at the bottom of the fan blades of the cooling fan 43. The second protective net 47 and the connector 46 are fixedly connected. By setting the second protective net 47, the bottom of the cooling fan 43 can be protected. By setting the connector 46, it is convenient to install the second protective net 47.

[0037] The second protective net 47 includes multiple rings 471 arranged equidistantly from the inside to the outside. Multiple fixing strips 472 and U-shaped strips 473 are welded at equal intervals at the bottom of the rings 471. The ends of the connectors 46 and the U-shaped strips 473 are fixedly connected by bolts. The cooling fan 43 is sleeved in the innermost ring 471. The fixing strips 472 can fix the multiple rings 471, and the U-shaped strips 473 can facilitate the connection of the connectors 46.

[0038] Furthermore, the protective mechanism 5 includes multiple protective plates 51 arranged at equal intervals, and side plates 52 are provided on both sides of the multiple protective plates 51. A pin 53 is movably connected between the protective plates 51 and the side plates 52. With this arrangement, when it rains, the protective plates 51 can be flipped inside the side plates 52 by the connection of the pins 53, covering the gap between the inner sides of any two adjacent protective plates 51, thereby playing a role in rain protection.

[0039] The side plate 52 is fixedly connected to a frame 54, which is fixedly connected to the top plate 3. The frame 54 is located directly above the heat dissipation mechanism 4. By setting the frame 54, the protective plate 51, the side plate 52 and the pin 53 can be installed and fixed.
