Abstract

The invention relates to an aircraft passenger cabin ceiling device with a drying function. The aircraft passenger cabin ceiling device with the drying function comprises a waterproof breathable filmand a cold plate, the cold plate is installed on an interior trim layer of an aircraft passenger cabin ceiling, the waterproof breathable film is installed to be separated from the cold plate, and a condensation cavity is defined between the waterproof breathable film and the cold plate. The aircraft passenger cabin ceiling device has the following beneficial technical effect that the drying function of the airplane passenger cabin ceiling and the heat and sound insulation cotton installed in the airplane passenger cabin ceiling can be achieved under the condition that electric energy is not used.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to an aircraft cabin ceiling device with a drying function. Background technique [0002] The operating environment of commercial aircraft is extremely complex. When the aircraft is cruising, the ambient temperature outside the cabin is about -55°C, and the moisture content in the air is almost zero. In the cabin, in order to ensure the comfort of passengers, the temperature inside the cabin is usually around 24°C , the moisture content is about 20%. Under the effect of humidity difference, the hot air in the cabin enters the heat insulation cotton through the ceiling of the cabin, and the other side of the heat insulation cotton is the low-temperature aircraft skin, and the hot air will condense in the heat insulation cotton. Once the condensed moisture has been absorbed by the insulation, it is very difficult to remove it. This will increase the weight of the aircraft, increas...
