Abstract
The utility model relates to a spiral-flow type air diffuser with a fairing, which comprises an air inlet and an air diffuser housing, wherein the air inlet is arranged at the upper end of the air diffuser housing; the air diffuser housing is internally provided with a conical fairing, a spiral-flow type hole plate and a fillet, the bottom surface of the conical fairing is fixedly connected with the fillet, two ends of the fillet is fixedly connected with the air diffuser housing, and the spiral-flow type hole plate is fixedly connected with the lower end of the air diffuser housing. The spiral-flow type air diffuser with the fairing is characterized by having no moving part and quick-wear part, as well as being simple and compact in structure and small in resistance, and the conical fairing plays a role in front-level rectifying and has the function of self cleaning; the air exhausted out of two rings of air outlets arranged on the spiral-flow type hole plate spirally at intervals can achieve full heat exchange and leads people to feel comfortable, thus achieving better air-conditioning effect.
Description
Technical field
The utility model relates to the central air-conditioning technical field, specifically is a kind of spiral-flow type air diffuser with radome fairing.
Background technology
Central air conditioning equipment is used widely in heavy construction, as bus station, railway station, airport and megastore etc.Supply air system in the central air conditioning equipment, particularly the terminal air diffuser of air-supply is its important part.Comparatively widely used at present air diffuser mainly contains: 1. split double-deck multipage square diffuser, its shortcoming is that fan resistance is bigger, and loss is more; 2. circular air diffuser, its shortcoming are that the air outlet wind direction can not be adjusted; 3. Ball shape nozzle formula, its shortcoming is to blow side, and can not be installed on the furred ceiling.The common drawback of above-mentioned several air diffusers is: the wind that blows out can not form turbulent flow, thereby causes the heat exchange effect insufficient.Another vortex air outlet device of the prior art (patent No. 200410088023.9), though its wind energy of sending forms turbulent flow, its shortcoming is, and movable member is more, and consumable accessory is more, and resistance is bigger, and maintenance capacity is big.
Summary of the invention
The purpose of this utility model provides a kind of spiral-flow type air diffuser with radome fairing, its movable member simple in structure, no, and no easily worn part, air-conditioning is effective.
The spiral-flow type air diffuser of described band radome fairing, comprise air inlet, air diffuser housing, air inlet is located at air diffuser housing upper end, it is characterized in that: in the air diffuser housing, be provided with taper fairing, spiral-flow type orifice plate and rib, fixedlying connected with rib in described taper fairing bottom surface, fixedlys connected with the air diffuser housing in the rib two ends, and described spiral-flow type orifice plate is fixedlyed connected with air diffuser housing lower end.
Described spiral-flow type orifice plate is provided with a circle or the spaced a plurality of air-out holes of multi-circle spiral flow formula.Described air-out hole is a rectangle.
The cone tip part of described taper fairing is on the air inlet central axis.
The utility model operation principle: in central air conditioner system, the hot and cold air of sending here from air supply duct is organized into 360 ° of uniform airflow through taper fairing earlier, and then the spiral spaced air-out hole of two circles penetrates from the spiral-flow type orifice plate, forms heat exchange turbulent flow fully.
Characteristics of the present utility model are: do not have movable piece and consumable accessory, simple in structure, compact, resistance is little, taper fairing has played the effect of prime rectification, and has self-cleaning function; Not only heat exchange is abundant for the wind that the spiral spaced air-out hole of two circles penetrates on the spiral-flow type orifice plate, and makes the people feel comfortable, reaches the air conditioning effect preferably.

Fig. 2 is the vertical view of Fig. 1,
Fig. 3 is the upward view of Fig. 1.
Among the figure: 1-air inlet, 2-air diffuser housing, 3-taper fairing, 4-rib, 5-spiral-flow type orifice plate, 6-air-out hole.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, among Fig. 1, the spiral-flow type air diffuser of described band radome fairing, comprise air inlet, air diffuser housing, air inlet is located at air diffuser housing upper end, it is characterized in that: be provided with taper fairing in the air diffuser housing, spiral-flow type orifice plate and rib, fixedlying connected with rib in described taper fairing bottom surface, fixedlys connected with the air diffuser housing in the rib two ends, and described spiral-flow type orifice plate is fixedlyed connected with air diffuser housing lower end.
Described spiral-flow type orifice plate is provided with a circle or the spaced a plurality of air-out holes of multi-circle spiral flow formula.
Described air-out hole is rectangle or other shapes.The cone tip part of described taper fairing is on the air inlet central axis
The course of work of the present utility model: in central air conditioner system, put 360 ° of uniform airflow of journey in order through taper fairing earlier from the hot and cold air that air supply duct is sent here, and then two groups of spiral spaced air-out holes penetrate from the spiral-flow type orifice plate, form heat exchange turbulent flow fully.
