The specific embodiment
Below in conjunction with drawings and Examples, the present invention will be further described:
Refer to Fig. 1, it is the structural representation that the present invention initiatively reclaims the enclosed air refrigeration cycle device of cold.
The open type air refrigeration cycle device of Passive intake cold, comprise the air turbine refrigerating channel and the Passive intake cold passage that are all connected with engine bleed, wherein, described Passive intake cold passage comprises primary heat sink 2, secondary radiator 4, fan 11, cold valve 10, condensator outlet air is communicated with cold air duct through cold valve, and primary heat sink 2 and the cold limit of secondary radiator 4 are positioned at cold air duct, and hot limit is positioned at air turbine refrigerating channel.
The valve passage of described cold valve 10 limits, and makes it when opening maximum rating, the air flow rate of process be still not more than 25% of total flow, avoid reducing passenger cabin cooling performance.
Flow control valve 1, primary heat sink 2, air compressor 3, secondary radiator 4, regenerator 5, condenser 6, water separator 7, turbine 8, passenger cabin 9, cold valve 10, fan 11, wherein, flow control valve is connected with engine high pressure bleed, in addition, and flow control valve 1, the hot limit of primary heat sink 2, air compressor 3, the hot limit of secondary radiator 4, the hot limit of regenerator 5, the hot limit of condenser 6, water separator 7, the cold limit of regenerator 5, turbine 8, the cold limit of condenser 6 is connected in passenger cabin in turn.
When the present invention initiatively reclaims the enclosed air refrigeration cycle device real work of cold,
The engine bleed regulating through flow control valve 1 is compressed into high temperature and high pressure gas by air compressor 3 after the hot limit of primary heat sink 2 is cooling, pass through successively the hotter limit of secondary radiator 4, the hot limit of regenerator 5, the hot limit of condenser 6 and water separator 7, further reduce temperature and isolate moisture, finally entering after turbine 8 expansions are lowered the temperature and confess through the cold limit of condenser 6.
Ram air is taken away system thermal by fan 11 suctions behind the cold limit of the cold limit of secondary radiator 4, primary heat sink 2.
The moisture injection that water separator 7 is separated enters the cold limit of secondary radiator 4, primary heat sink 2 is taken away system thermal behind cold limit.
The cold limit of condenser 6 air is divided into two-way, one tunnel feeds passenger cabin 9, one tunnel enters the cold sideband walking system heat of the cold limit of secondary radiator 4, primary heat sink 2 after cold valve 10 adjust fluxes, thereby can effectively reduce the air inlet demand to ram intake, therefore can reduce the flow area of ram intake, by actual tests, it is original 40% that ram intake area can be reduced to, and reaches 0.1m
2thereby, significantly reduce the compensatory loss of aeroplane performance, meet the stealthy demand of High Performance operational aircraft.
