Description

It is a kind of for/the synthesis thermojet driver of frost/ice and the application of dehumidifying
Technical field
The invention belongs to fluidics field more particularly to it is a kind of for dehumidify/the synthesis thermojet driver of frost/ice and Using.
Background technology
Icing is a kind of phenomenon being widely present in aircraft flight, and cause flight safety accident main hidden danger it One.When aircraft flight under the conditions of subfreezing icing meteorology, the super-cooling waterdrop in air strikes aircraft surfaces, freezes Phenomenon is just easy to occur in parts surfaces such as wing, empennage, rotor, air intake duct, windshield, antenna house, gauge sensors. Aircraft, which freezes, not only increases the weight of aircraft, and destroys the aerodynamic configuration of aircraft surfaces, changes Flow Field, destroys Aeroperformance causes aircraft maximum lift to decline, flight resistance rises, operating characteristics declines, stability reduces, primary rank The accumulated ice of section can substantially reduce lift and increase resistance.Currently, the anti-deicing system on passenger plane, which includes mainly gas heat, prevents/deicing Prevent/deicing two ways with electric heating.Both anti-/ deicing modes consume energy, and big, increase quality is big, is suitable for large aircraft.And it is right It being difficult to adapt to if some middle-size and small-size aircraft such as unmanned plane, one side unmanned plane is easier to freeze and harm is more serious, nobody Machine cabinet size is small, it is easier to which freeze (under the same terms, aircraft is smaller, easier icing), the opposite thickness that freezes of unit interval Degree is big (the smaller anti-ice ability of aircraft is poorer), and the harm that the ice of same thickness generates aircraft is more serious;On the other hand, unmanned plane Payload is small, and fuel oil carrying amount is limited, and the energy is most valuable on machine, and big energy cannot be consumed as large aircraft and is prevented and kill off Ice.
Automobile front and rear windshield, rearview mirror generally existing fogging frosting problem, since vehicle internal-external temperature difference makes interior moisture Mist or frost are formed to the cold and in inside glass, seriously affects traffic safety.At present automobile demisting mainly by air conditioner dehumidification come Carry out demisting.Defrosting just needs to open warm wind, and radiating fin of hot air machine is flowed through by the water that engine comes, and starts fan, diffusion The heat that engine comes.Defrosting process needs first hot vehicle, and engine water temperature is waited for rise, and opens warm-air drier defrosting later, compares Take time and effort oil consumption.Sleety weather rearview mirror is easy attached water and drips mist, seriously affects traffic safety, generally passes through electric heating at present Piece heats glass back and carries out demisting and evaporation water droplet, very time-consuming power-consuming.
In daily life, travelling and outdoor sports, generally existing dehumidifying, removes ice problem at defrosting, as frosting freezes in refrigerator Refrigeration for refrigerator effect is caused to decline;The rainy water of winter-spring season, especially southern area, weather cool, damp, the clothing cleaned Be not easy to dry, footgear it is moist;In travelling and outdoor sports, we usually also have such puzzlement:Clothes footgear cannot dry in the air in time It is dry, tent and sleeping bag are clammy etc..
