In the case of an air conditioner, the wind speed at the air outlet is approximately 0.5m/s to 4m/s, and in the case of 4m/s, after the wind is guided by a common plate-shaped air guide plate, the wind speed can be reduced to approximately 0 after a distance of about 5 m. After the air guide plate assembly, the wind speed can be reduced to 0 approximately after the distance of about 2m, the blown air flow and indoor air can fully exchange heat in the range of blowing out 2m from the air outlet to the air flow, and the wind speed is extremely low after 2m is opened.
Referring to fig. 9, when the airflow blows along the width direction of the
In addition to the above-described embodiments, the wing plate is attached to the air guide surface in an inclined manner, but the angle of inclination of the wing plate itself cannot be too large or too small. The inclination of the

Theoretically, even if α is equal to 0, the vortex can be formed when the airflow flows from the front edge to the rear edge of the wing plate, but the vortex amount of the vortex is relatively small, the vortex strength is weak, in order to make the vortex effect relatively good, α can take 5 degrees, and the subsequent data can observe the vortex degree and the vortex amount when α changes from 15 degrees to 70 degrees.
Referring to fig. 10a to 10h, it can be seen that the vortex strength is weak when α is 15 °, the vortex condition changes significantly when α is 70 °, the wing tip vortex degree is weak, the wing tip vortex condition is relatively ideal when α is 15 ° to 70 °, and the value range of the adaptive attack angle α can be determined to be 15 ° to 70 ° according to numerical simulation
Referring to fig. 10a to 10h, the swirl strength is stronger in the range of α ° to α ° to 55 °, and the difference is that the influence range of the swirl wake is smaller when α ° to 15 ° and α ° to 25 °, which is not favorable for driving the rear air to rotate, the swirl condition is significantly changed when α ° to 70 °, the wing tip swirl degree is weak, and the wing tip swirl condition is ideal when α ° to α ° to 55 °.
The effect of α on vortex wake is not sufficiently judged by streamline distribution alone-vorticity is the physical quantity reflecting the strength of vortex, and the contour distribution of vorticity around the wing is shown in FIGS. 11a to 11 h.
The vortex core (solid portions on both sides of the wing plate in fig. 11a to 11 h) of the vortex wake is the largest when the incident angle α is 15 ° and the vortex core 28 is 25 °, but as the streamline distribution in fig. 10a to 10h is known, the wake influence range is relatively small because the incident angle α is small, so that the angle is suitable for a use situation where the air supply is far away and the heat exchange efficiency needs to be enhanced, α ° to α ° range is 55 °, the vortex distribution situation is close, and the incident angle α is larger, so that the capability of scattering the incoming flow is stronger, so that the effect of swirling the air flow into the wake is best when α ° is 55 °, α ° to α ° is suitable for the air supply short distance and the design requirement of soft feeling is strong, when the incident angle α is too large, the rising
The streamline and velocity profiles obtained by numerical simulation calculations are shown in fig. 17 and 18. At the initial stage, the air flow speed guided out by the
