Abstract
The work aims to investigate the refrigeration performance of water evaporation coolers under high-altitude flight conditions and provide theoretical and experimental data support for engineering applications. Firstly, theoretical calculation methods were used to evaluate the refrigeration performance of water evaporation coolers under different flight conditions based on application scenarios. Then, an experimental setup was constructed to simulate operating environments with varying pressure, temperature, and humidity. Performance tests were conducted on the water evaporation cooler under these conditions to obtain test data. The theoretical calculation method was closely integrated with application factors such as flight conditions, weather parameters, flight altitude, speed, air humidity, and flow resistance characteristics of the water evaporation cooler. These factors enabled the evaluation of the cooler's refrigeration performance. Experimental simulations further validated the effectiveness of the theoretical calculation method by testing the cooler's performance under diverse operating conditions, providing an efficient design pathway for engineering applications. Theoretical analysis and experimental results demonstrate that water evaporation coolers exhibit high refrigeration performance and reliability in practical applications. The coolers can be applied to improve the operational temperature environment of onboard equipment as well as enhance the functional reliability and environmental adaptability of civil aircraft.
