Description

Technical Field

[0001] This utility model relates to the field of refrigeration, specifically to an evaporative cooling system for transport aircraft air conditioning. Background Technology

[0002] Existing air conditioning systems for transport aircraft suffer from problems such as low cooling efficiency, high energy consumption, and inconvenient maintenance. Traditional refrigeration units are ill-suited to the complex and variable working environment of transport aircraft, and their cooling performance is significantly affected by factors such as outside temperature and flight altitude. When transport aircraft are in high-temperature and high-humidity environments, the cooling capacity of the air conditioning system will decrease significantly due to power limitations, resulting in ineffective temperature reduction in the cockpit and cabin, affecting the working comfort of the crew and the normal operation of equipment.

[0003] Furthermore, traditional airborne air conditioning systems are inefficient in terms of energy consumption. Their compressor systems utilize the aircraft's engine output for power, increasing the overall energy burden on the transport aircraft and reducing fuel economy. In addition, their complex structural design and inefficient connection and layout of components make routine maintenance and troubleshooting difficult, consuming significant time and manpower costs, and severely impacting the transport aircraft's operational efficiency and operating costs. Summary of the Invention

[0004] In order to meet the high-power cooling requirements of transport aircraft, reduce energy consumption, and facilitate maintenance, this utility model provides a transport aircraft air conditioning evaporative cycle cooling device.

[0005] The technical solution adopted by this utility model is as follows: A transport aircraft air conditioning evaporative cooling system includes a condenser assembly, a left evaporator assembly, a right evaporator assembly, and a mounting base. The mounting base is fixedly installed in the cockpit of the transport aircraft. The condenser assembly is fixedly installed on the mounting base. The condenser assembly includes a condenser housing. A left heat exchange core and a right heat exchange core are installed side by side inside the condenser housing. An air inlet pipe and an air outlet pipe are respectively installed on the side of the condenser housing parallel to the heat exchange cores. The air inlet pipe and the air outlet pipe are respectively connected to the inside of the condenser housing. A fan is installed at the connection between the air inlet pipe and the condenser housing. The end of the air inlet pipe extends to the side of the transport aircraft and communicates with the outside air. The end of the air outlet pipe extends vertically downward to the bottom of the transport aircraft and communicates with the outside air. A left compressor and a right compressor are fixedly installed on the mounting base. The suction end of the left compressor is connected to the left evaporator through a pipe, and the discharge end of the left compressor is connected to the left condenser. The suction end of the right compressor is connected to the right evaporator through a pipe, and the discharge end of the right compressor is connected to the right condenser.

[0006] Furthermore, a water collection tray is provided directly below the heat exchange core of the evaporator and the condenser respectively. The bottom of the water collection tray in the evaporator is connected to the condenser housing through a drain pipe and a drain solenoid valve. The interface between the drain pipe and the condenser housing is located directly above the corresponding heat exchange core in the condenser.

[0007] Furthermore, the left evaporator assembly and the right evaporator assembly each include a housing, on which an air inlet and an air outlet are provided. The air inlet is connected to a return fan via a pipe, and the air outlet is connected to an air supply system via a pipe.

[0008] Furthermore, the air supply system includes a main air supply pipe, the air outlet of the evaporator is connected to the main air supply pipe through an air valve, the main air supply pipe is connected to a ground air supply pipe and a refrigeration unit through an air valve, and the main air supply pipe has multiple air supply branches.

[0009] Furthermore, the two sides of the condenser housing are respectively fixedly connected to the mounting base via connecting plates.

[0010] Furthermore, the left and right compressors are electric compressors.

[0011] Furthermore, a wind cap is installed at the protruding end of the air outlet pipe extending from the bottom of the conveyor, and the wind-facing surface of the wind cap is closed by a spherical end cap.

[0012] Furthermore, it also includes a refrigeration control panel and a refrigeration control box. The refrigeration control panel is connected to the refrigeration control box and sends commands to the refrigeration control box. It also controls the various components in the evaporation cycle refrigeration device through the control circuit in the refrigeration control box.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: The condenser assembly and compressor are centrally mounted and secured using mounting brackets, facilitating subsequent installation and maintenance. The dual compressors and dual condensers effectively increase the system's cooling capacity, meeting the cooling requirements of the transport aircraft. The use of electric compressors offers higher energy efficiency compared to traditional compressors, reducing overall energy consumption and operating costs. Furthermore, electric compressors operate more stably, reducing vibration and noise, thus improving the user experience. The condenser utilizes external aircraft airflow for cooling and exhausts hot air to the outside of the aircraft, providing a large airflow and excellent heat exchange effect, meeting the demands of high-power heat exchange. Condensate from the evaporator is controlled by pipes and valves to be sent to the condenser core for further cooling, resulting in a more ideal cooling effect. Attached Figure Description

It is used for cooling the cabin, equipment compartment, work compartment, and command cabin of the transport aircraft. The cooling control panel 5 is connected to the cooling control box 6 and sends commands to the cooling control box 6, controlling the various components within the evaporative cooling cycle system through the control circuit within the cooling control box 6. This technical solution employs a design with dual compressors, dual evaporators, and dual condensers to meet the cooling needs of the large, multi-compartment space of the transport aircraft.

[0018] Mounting base 4 is fixedly installed in the cockpit of the transport aircraft. Condenser assembly 1 is fixedly installed on mounting base 4. Condenser assembly 1 includes a condenser housing. The two sides of the condenser housing are fixedly connected to mounting base 4 via connecting plates 7. A left heat exchange core and a right heat exchange core are installed side by side inside the condenser housing.

The end of the air inlet pipe extends to the side of the transport aircraft and connects with the outside air. The end of the air outlet pipe 9 extends vertically downward to the bottom of the transport aircraft and connects with the outside air. A wind cap 10 is installed at the protruding end of the air outlet pipe 9 extending out of the bottom of the transport aircraft. The wind-facing surface of the wind cap 10 is sealed by a spherical end cap to prevent outside air from flowing back into the air outlet pipe and affecting the cooling effect.

[0019] The left compressor 11 and right compressor 12 are fixedly mounted on mounting base 4. The suction end of the left compressor 11 is connected to the left evaporator assembly 2 via a pipe, and the discharge end of the left compressor 11 is connected to the left heat exchange core. The suction end of the right compressor 12 is connected to the right evaporator assembly 3 via a pipe, and the discharge end of the right compressor 12 is connected to the right heat exchange core. Both the left compressor 11 and right compressor 12 are electric compressors. Using electric compressors eliminates the need for the aircraft engine's power output, allowing the air conditioning system to be arranged away from the engine location, improving its layout flexibility and facilitating maintenance. Using electricity also saves energy. A liquid receiver and expansion valve are also connected in series on the pipes between each condenser and evaporator.

[0021] A water collection tray is installed directly below the heat exchange core of each evaporator and condenser. The bottom of the water collection tray in each evaporator is connected to the condenser housing through a drain pipe and a drain solenoid valve. The interface between the drain pipe and the condenser housing is located directly above the corresponding heat exchange core in the condenser. This allows the condensate generated in the evaporator to be returned to the condenser core for evaporation, further improving the efficiency of the condenser.
