Description

technical field [0001] The invention relates to aircraft ground support equipment, in particular to a towed aircraft air cooler capable of providing cooling air with low dew point and high pressure for aircraft. Background technique [0002] A general aircraft air cooler trailer includes a trailer chassis, external power connector, air conditioning unit, operation control system and pipeline accessories. Its main function is to provide cooling air with a certain flow rate, temperature and pressure according to the requirements of the guaranteed equipment. At present, most of the existing air coolers for aircraft use high-pressure centrifugal fans or Roots fans as power sources, and use evaporative refrigeration to adjust the temperature of the provided cooling air. The temperature-regulated air provided by the aircraft air cooler in the prior art often has a high dew point and low pressure, which cannot meet the needs of some equipment that has special requirements for the d...

AI Technical Summary

Problems solved by technology

The temperature-regulated air provided by aircraft air coolers in the prior art often has a high dew point and low pressure, which cannot meet the needs of some equipment with special requirements for the air dew point and air pressure.

Simply increasing the air supply pressure or increasing the power of the compressor will only increase the size of the equipment or cause poor system matching. The direct result is that the quality of the air supply is poor or the energy consumption of the product is increased. The cost of equipment is increased, and the defects and deficiencies of high dew point and low pressure in the aircraft air cooler in the prior art cannot be well solved, and the use requirements cannot be met
