The baffle 3 is used for separating an area needing deicing from a non-deicing area, and the area needing deicing is ensured to be a closed space, so that the flowing area of hot gas is limited, and the heat utilization rate is improved. The supporting piece 4 is used for supporting the heat conduction air cushion to be tightly attached to the inner surface of the blade 01, so that the heat conduction efficiency of the heat conduction air cushion to the blade 01 is improved, and the deicing effect of the gas-heated deicing device to the blade 01 is further improved. The gas outlet pipe 5 conveys gas exhausted from the blade to the gas heating mechanism, and the gas is compressed and heated again and then recycled, so that the heat utilization rate of the gas can be improved through the recycling of the gas.
The gas-heated deicing device in embodiment 6 uses the special structure of the gas inlet pipe 1 to transmit the gas compressed and heated by the gas heating mechanism to the blade 01 through the gas inlet pipe 1, and uses the gas injection holes on the gas inlet pipe 1 to inject hot gas, so that the heat is conducted to the blade 01 to realize the deicing effect. In embodiment 6, the adjustable sealing plate 6 can meet the actual deicing requirement and avoid the possibility of icing any part of the blade 01 by adjusting the size or opening and closing of the opening of the exhaust port.
The gas-heated deicing apparatus described in embodiments 1-6 above can meet the gas supply requirements of multiple groups of gas-heated deicing assemblies by only selecting one gas heating mechanism, which is disposed in the cabin cabinet 02. Compared with the prior art that the air blower and the heater are arranged inside the blade, the gas heating mechanism in the embodiments 1-6 greatly simplifies the construction difficulty and reduces the lightning risk.
