Abstract
The invention relates to a mixed flow device for cold air and hot air. The mixed flow device comprises a cold fluid inlet (1), a hot fluid inducting pipe (2), a rotational flow device (3), a water collector (4), a water draining mouthpiece (5), a fluid outlet (6) and a mixed cavity casing (7), wherein the cold fluid inlet (1) is formed in one end of the mixed cavity casing (7), the hot fluid inducting pipe (2) is arranged at the downstream position of the cold fluid inlet (1) and extends to the inner part of the mixed cavity casing (7), the rotational flow device (3) is arranged at the middle part of the mixed cavity casing (7), the fluid outlet (6) is formed in the other end of the mixed cavity casing (7), and the water collector (4) and the water draining mouthpiece (5) are arranged at upstream positions near the fluid outlet (6). According to the mixed flow device for cold air and hot air disclosed by the invention, the rotational flow device is additionally mounted in the mixed cavity body, and the cold fluid and the hot fluid are sufficiently mixed in a shorter flowing process; besides, the water collecting function is considered; the condensate water which is produced in air supply is collected by a water collecting box and is drained through a water draining pipeline, so that the air supply quality can be improved.
Description
Technical field
The invention belongs to field of airplane environment control.
Background technology
Aircraft environmental control system, when to cabin air supply, controls suitable feed air temperature generally by the flow proportional regulating hot and cold road. Typically require and monitor pipeline feed air temperature by temperature sensor, and the installation point of pipeline feed air temperature sensor requires that air themperature must mix homogeneously herein. Owing to the coefficient of heat transfer of air is relatively low, under certain flow velocity, cold and hot fluid to reach temperature mixing uniformly it is generally required to longer mixing section. And owing to being limited by installation site and space on aircraft, it is impossible to longer pipeline space is provided. Simultaneously as moisture is higher in hot-air, generally usually there will be condensed water during the mixing of hot and cold air, if pipeline water removal effect is bad, water droplet can spray along with air supply opening, affects occupant comfort.
Summary of the invention
Goal of the invention
The invention aims to solve the problem of hot and cold road pipeline feed air temperature mix homogeneously in the confined space. The temperature mixing that the present invention realizes air in limited flow process is uniform, the condensing drip produced when being simultaneously conducive to separating and collecting the mixing of hot and cold air, improves quality of filling gas.
Technical scheme
The flow mixing device of a kind of hot and cold air, the flow mixing device of described hot and cold air is spigot joint 5 by cold fluid inlet 1, hot fluid ingress pipe 2, swirl-flow devices 3, water collector 4, draining, fluid issuing 6 and hybrid chamber housing 7 form. Wherein, hybrid chamber housing 7 is hollow cavity, it is provided with cold fluid inlet 1 in its one end, downstream part at cold fluid inlet 1 is provided with hot fluid ingress pipe 2 and extends to inside hybrid chamber housing 7, it is provided with swirl-flow devices 3 at the middle part of hybrid chamber housing 7, the other end of hybrid chamber housing 7 is provided with fluid issuing 6, is provided with water collector 4 and draining spigot joint 5 in the upstream section near fluid issuing 6.
Preferably, hot fluid ingress pipe 2 stretches into the part within hybrid chamber housing 7 and adopts bourdon's tube form.
Beneficial effect
The present invention has installed swirl-flow devices additional in cavity, makes cold fluid and hot fluid be sufficiently mixed in relatively short route, takes into account moisture collection effect simultaneously, the utilization of condensed water water disposable box produced is collected and is discharged by discharge pipe line, improve quality of filling gas in supply.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention
Detailed description of the invention
Referring to Fig. 1, cold flow body enters in hybrid chamber housing 7 by cold fluid inlet 1, hot fluid enters in hybrid chamber housing 7 by hot fluid ingress pipe 2, cold and hot fluid mixes in hybrid chamber housing 7, under the effect of swirl-flow devices 3, the turbulent flow aggravation of cold and hot fluid, mixing sufficiently achieves homogeneous temperature. For air, the condensed water produced in hot and cold air mixed process is collected by water collector 4, discharges again through draining spigot joint 5. It is uniform that mixed air reaches temperature mixing at fluid issuing 6 place.
Embodiment
The air mass flow distribution system of aircraft adopts the mode of hot and cold road mixing to regulate the final air themperature feeding passenger cabin, and temperature needs suitable measurement point to measure pipeline feed air temperature when controlling. But due to passenger cabin limited space, hot and cold air mixture length is shorter. Therefore have employed cold flow body and enter hybrid chamber housing 7 by cold fluid inlet 1, hot fluid enters hybrid chamber housing 7 by hot fluid ingress pipe 2, and cold and hot fluid mixes in hybrid chamber housing 7, under the effect of cyclone 3, the turbulent flow making cold and hot fluid is aggravated, and mixing is fully. The condensed water produced in hot and cold air mixed process is collected by water collector 4 simultaneously, discharge again through draining spigot joint 5. It is uniform that mixed air reaches temperature mixing at outlet 6 places. Measurement for passenger cabin pipeline feed air temperature provides suitable position.
