Efficient induced type air blowing opening according to the utility model provides is characterized in that, between described vertical vertical pivot (6) is fixedly installed on intermediate clapboard (3) and the tuyere shell (4) by ball bearing and fixing rod.
Efficient induced type air blowing opening according to the utility model provides is characterized in that, when described air vane is subjected to the wind pushing air driving, makes the rotation of axial fan blade (2) interlock by vertical vertical pivot, the suction indoor air; Described intermediate clapboard (3) is divided into the primary air space on top and the secondary air space of bottom with the vertical space in air port; And described tuyere shell (4) and axial fan suction port (5) and intermediate clapboard (3) constitute diffusing opening, enter in the air conditioning chamber after first and second even air is mixed.
Efficient induced type air blowing opening according to the utility model provides is characterized in that the number of blade of described windmill is three.
Efficient induced type air blowing opening according to the utility model provides is characterized in that the number of blade of described axial fan is four.
Implement efficient induced type air blowing opening of the present utility model and since its unique windmill/fan assembly efficiently induce performance, derivative coefficient reaches 2.68, is much higher than the maximum induction ratio (＜1.6) in other passive induced type air port both at home and abroad.Therefore, diffusion is good, and velocity attenuation is fast, and the big temperature difference is closely blown becomes possibility.Because volume is little, can build and pipeline space by saving equipment, need not again the power consumption of heat energy consumption and inducing device, reduce once investment and operating cost effectively.
In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present utility model, in the accompanying drawing:
Fig. 1 is the structure sectional view of efficient induced type air blowing opening of the present utility model.
Fig. 2 is the plane structure schematic representation of efficient induced type air blowing opening of the present utility model.
Fig. 3 is an efficient induced type air blowing opening of the present utility model airflow pattern schematic representation in use.
As depicted in figs. 1 and 2, efficient induced type air blowing opening of the present utility model comprises: tuyere shell (4), place the windmill/fan assembly in the described tuyere shell, described windmill/fan is made up of vertical vertical pivot (6) and the air vane (1) and the fan blade (2) that are contained in these vertical vertical pivot (6) two ends respectively, between described air vane (1) and fan blade (2), be provided with intermediate clapboard (3), be provided with ring-like axial flow air inlet (5) around the described fan (2).Wherein:

Divide three aspect explanations to implement feasibility Experiment result of the present utility model below:
1. general understanding
By experiment, the efficient induced type air conditioning air outlet that the utility model provides, when the main wind passage wind speed was 2.88m/s, as the family expenses fan by driven by motor, fan rotated very fast.The rotation of fan is changeed slowly with the reduction of main wind passage air supply velocity, even but also keep slow rotation when air supply velocity is about 0.8m/s.Induce air quantity (secondary air amount) to increase and decrease, confirmed the works fine characteristic and the self-regulating function of the core component windmill/fan assembly of this patent along with the increase and decrease of air supply velocity.
2. derivative coefficient
At air supply velocity is under the condition of 2.88m/s, and the induction ratio coefficient with secondary air/primary air definition of being calculated indirectly by various test parameters is 2.68, is higher than the derivative coefficient (＜1.6) in existing various induced types air port both at home and abroad far away.
3. airflow pattern
The airflow pattern of Fig. 3 for drawing according to experimental result.Air-flow is divided into two strands after the exhaust port ejection, one direction of outside is the mixing divergent flow of a secondary gas flow down, and middle one makes progress, flows to the induced draft of fan center for direction.The separating surface of one secondary gas flow is a big down little cone, and it is gone to the bottom is being that 1 meter diameter is about 1 meter from the air port perpendicular distance.The wind speed and the temperature of working area are even, and wind speed is less than 1m/s, and temperature is 23-25 ℃.At supply air temperature difference is under the big temperature difference of 15 ℃ (8.9 ℃ of wind pushing temperatures, 30 ℃ of indoor internal calorific power equivalent temperatures), does not have the sense of blowing a cold wind over, and satisfies the design condition of comfort air conditioning.
According to above result, can see that the utility model can be widely used in the hotel, computer room, personnel such as air-conditioned train compartment are intensive, and the air-supply of the air-conditioning system that internal calorific power is big has very large commercial application potential and use prospect.
