Wherein, electromotor 1, flow-control valve 2, primary heat sink 3, compressor 4, secondary radiator 5, regenerator 6, cold
Condenser 7, water separator 8, turbine 9, passenger cabin 10, fan 11, cold valve 12, pressure tank 13, air register 14.
Detailed description of the invention
The present invention will be further described with embodiment below in conjunction with the accompanying drawings:
Referring to Fig. 1, it is the structural representation that the present invention actively reclaims the closed air refrigerating circulatory device of cold.
Actively reclaiming the closed air refrigerating circulatory device of cold, it includes the air turbine being all connected with engine bleed
Refrigerating channel and actively reclaim cold passage.Wherein, the described cold passage that actively reclaims includes primary heat sink 3, secondary heat radiation
Device 5, fan 11, cold valve 12, pressure tank 13, air register 14, engine high pressure bleed is successively through cold valve, pressure tank
Connect with cold air duct, contain bleed outside electromotor and be connected with cold air duct through air register 14, primary heat sink 3 and secondary radiator 5
Cold limit is positioned at cold air duct, and hot limit is positioned at Refrigeration by air turbine passage, and cold air duct closes on one section of setting of engine exhaust port
There is the fan 11 for suction.
Refrigeration by air turbine passage includes flow-control valve 2, primary heat sink 3, compressor 4, secondary radiator 5, returns
Hot device 6, condenser 7, water separator 8, turbine 9, passenger cabin 10.Wherein, flow-control valve is connected with engine high pressure bleed, separately
Outward, flow-control valve 2, the hot limit of primary heat sink 3, compressor 4, the secondary hot limit of radiator 5, the hot limit of regenerator 6, condenser 7
Hot limit, water separator 8, the cold limit of regenerator 6, turbine 9, the cold limit of condenser 7 is sequentially connected with in passenger cabin.
The atomizer of described pressure tank and water separator 8 is arranged in cold air duct, is used for being atomized cooling and improves primary
Radiator 3, the heat exchange efficiency of secondary radiator 5.
When the present invention actively reclaims the closed air refrigerating circulatory device real work of cold,
Through flow-control valve 2 regulation electromotor 1 bleed through the hot limit of primary heat sink 3 cool down after by compressor
4 are compressed into high temperature and high pressure gas, then sequentially pass through the secondary hot limit of radiator 5, the hot limit of regenerator 6, the hot limit of condenser 7 separate with water
