Abstract
The utility model relates to a kind of outlet pipe heater, especially a kind of outlet pipe heater that is applicable to assemble piston-engined military aircraft.An outlet pipe heater, comprises inner casing, is provided with longitudinal radiating fin on described inner casing, and described radiating fin in the shape of a spiral; Described inner casing is coated with shell, is provided with fresh cold air suction port and air outlet on shell.The utlity model has following advantage: 1, directly utilize the heat of the useless exhaust of engine thermal, without again extracting power from motor, reduced oil consumption rate, and on the work of motor without impact.2, radiating fin in the shape of a spiral, has increased heat exchange area and heat-exchange time, has improved heat exchange efficiency.3, fresh cold air gas passage is in the shape of a spiral, smooth smooth and easy, and air-flow local losses is little, and flow resistance is little, has increased bleed flow, has improved heat exchange efficiency.4, the shell of heater, inner casing and radiating fin have adopted high-temp antioxidizing material 1Cr18Ni9Ti, have good weldability, are convenient to manufacture.5, the 1Cr18Ni9Ti material that outlet pipe heater adopts has good thermal conductivity, has improved heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of outlet pipe heater, especially a kind of outlet pipe heater that is applicable to assemble piston-engined military aircraft.
Background technique
Assemble piston-engined military aircraft (particularly below 0 ℃ time) in the situation that atmospheric temperature is low, because passenger cabin is non-tight passenger cabin, cause cabin temperature too low, have a strong impact on pilot's comfort level and operant response ability.In view of above reason, taked in the past thermal cloth, thermal glove mode or grounding measure under severe cold weather condition.
Domestic research installed air-conditioning system and sealed cabin additional at present, but install air-conditioning additional, need improve engine power, and requires motor to do the adaptability change on structure and interface.Because above-mentioned change need require the change of aircraft and motor excessive compared with long lead time and a large amount of research expenditure, existing in the project study stage, cannot meet the urgent demand of domestic present stage.
Summary of the invention
The purpose of this utility model is to solve problems of the prior art, provide a kind of simple in structure, heat transfer rate is high and be applicable to assemble the outlet pipe heater of piston-engined military aircraft.
For achieving the above object, the utility model adopts following technological scheme: a kind of outlet pipe heater, comprise inner casing, and on described inner casing, be provided with longitudinal radiating fin, described radiating fin is in the shape of a spiral; Described inner casing is coated with shell, is provided with fresh cold air suction port and air outlet on shell.
Outlet pipe heater utilizes helical radiating fin the heat of the useless exhaust of engine thermal to be passed to the fresh air of introducing, and by the defeated only passenger cabin of the fresh air after heating, improves cabin temperature, and this scheme principle is clear and definite, is simple and easy to implement.
The utlity model has following advantage:
1, the heat that directly utilizes the useless exhaust of engine thermal, without again extracting power from motor, has reduced oil consumption rate, and on the work of motor without impact.
2, radiating fin in the shape of a spiral, has increased heat exchange area and heat-exchange time, has improved heat exchange efficiency.
3, fresh cold air gas passage is in the shape of a spiral, smooth smooth and easy, and air-flow local losses is little, and flow resistance is little, has increased bleed flow, has improved heat exchange efficiency.
4, the shell of heater, inner casing and radiating fin have adopted high-temp antioxidizing material 1Cr18Ni9Ti, have good weldability, are convenient to manufacture.
5, the 1Cr18Ni9Ti material that outlet pipe heater adopts has good thermal conductivity, has improved heat exchange efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be further described: a kind of outlet pipe heater, comprise inner casing 1, on described inner casing 1, be provided with longitudinal radiating fin 10, described radiating fin is in the shape of a spiral; Described inner casing is coated with shell 2, is provided with fresh cold air suction port 20 and air outlet 21 on shell, and the fresh air after heating leads to passenger cabin by air outlet 21.
Helical radiating fin is welded on inner casing and forms helical air-flow path, and the useless exhaust of engine thermal is in the internal channel circulation of inner casing; The material of described outlet pipe heater is 1Cr18Ni9Ti.
Outlet pipe heater diabatic process: engine thermal exhaust (hot air temperature) T1 → heater inner casing (wall surface temperature) T2 → radiating fin (wall surface temperature) T3 that gives up, temperature is conduction decline trend; Extraneous fresh cold air relies on heater inner casing wall T2 and radiating fin wall T3 to conduct heat after entering heater, forms hot gas and leads to aircraft cockpit, to improve Aircraft Cabin Temperature.Air-flow conducts heat and mainly relies on heater inner casing and radiating fin, radiating fin to allow the fresh cold air that enters heater flow at heater internal spiral, to improve air-flow heat exchange efficiency in the process of circulation in heater.
Claims (2)
1. an outlet pipe heater, comprises inner casing, it is characterized in that: on described inner casing, be provided with longitudinal radiating fin, described radiating fin in the shape of a spiral; Described inner casing is coated with shell, is provided with fresh cold air suction port and air outlet on shell.
2. outlet pipe heater according to claim 1, is characterized in that: the material of described outlet pipe heater is 1Cr18Ni9Ti.
