The utility model discloses the reality has provided an aviation baffle subassembly and has included the air conditioner of this aviation baffle subassembly, and this air conditioner can be split type air conditioner or integral air conditioner. Regarding the air conditioner, the following description will be made with respect to a split type air conditioner (floor type air conditioner indoor unit) as a specific embodiment.
Referring to fig. 1 to 5, the wind deflector assembly 10 includes a wind deflector 11 and a wing plate 12. The air deflector 11 is provided with an air guiding surface 11 a; the wing plate 12 is obliquely attached to the air guide surface 11a by a connector 13, the wing plate 12 has a front edge 121, a rear edge 122, a front surface 12a and a rear surface 12b, the front edge 121 and the rear edge 122 are connected to the front surface 12a and the rear surface 12b, an air gap P (see fig. 3 in detail) is provided between the front edge 121 and the air guide surface 11a, a distance between the front edge 121 and the air guide surface 11a is smaller than a distance between the rear edge 122 and the air guide surface 11a, and the rear surface 12b is located between the front surface 12a and the air guide surface 11 a.
The air guide plate 11 has a substantially square plate-like structure, and the air guide plate 11 itself has a first side and a second side extending in the longitudinal direction thereof and disposed to face each other, and the air guide plate 11 also has a leeward surface 11b facing the air guide surface 11a (the leeward surface 11b has an air guide function when it is at a certain angle). Of course, the wind guide plate 11 may have a certain curvature, for example, the wind guide surface 11a may have a certain concave curvature, and the leeward surface 11b may have a certain curvature.
Referring to fig. 6-8, wing panel 12 is configured, as the name implies, like a wing of an aircraft. The leading edge 121 of the wing panel 12 refers to the front edge of the wing panel 12 facing the wind, and the trailing edge 122 refers to the trailing edge of the wing panel 12 facing the wind, that is, when the wing panel 12 faces the wind, the airflow flows from the leading edge 121 to the trailing edge 122. For this airfoil section, the arc length of the back face of wing panel 12 (the arc length extending from leading edge 121 along back face 12b to trailing edge 122) is greater than the straight or arc length of ventral face 12a of wing panel 12. For the wing panel 12, the wing panel 12 itself also has two side surfaces 12c between the ventral surface 12a and the dorsal surface 12b, with the span L referring to the spacing between the opposite side surfaces of the wing panel 12 (for a uniform spacing between the two side surfaces 12 c). The chord length C is indicative of the straight distance between the leading edge 121 and the trailing edge 122. Distance L between the leading edge 121 and the maximum thickness of the wing panel 121Less than the distance L between the trailing edge 122 and the maximum thickness of the wing panel 122. The back surface 12b may be a curved surface, and the ventral surface 12a may be a flat surface or a curved surface.
For the installation of the wing plate 12 and the air guiding plate 11, the wing plate 12 itself has a certain distance with the air guiding surface 11a so as to facilitate the air flow to pass through, and the wing plate 12 and the air guiding plate 11 are connected by the connecting piece 13, on one hand, the connecting piece 13 may be a columnar structure, or may be a regular or irregular protrusion arranged on the air guiding surface 11a, or of course, may be a regular or irregular protrusion arranged on the surface of the wing plate 12. On the other hand, the connector 13 may have one end connected to the air guide surface 11a and the other end connected to the side surface, the back surface 12b, or the ventral surface 12a of the wing plate 12. On the other hand, the connecting member 13 may also be a sheet-like structure, for example, the sheet-like structure extends along the airflow direction, so that on the one hand, the sheet-like structure can play a role in guiding the airflow, on the other hand, the sheet-like structure can also reduce the airflow resistance, and on the other hand, the sheet-like structure also has a certain dividing role in the airflow passing through the air guiding surface 11a, so as to slow down the formation of.
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 the indoor air can fully exchange heat in the range of blowing out 2m from the air outlet to the air flow, and almost no wind feeling exists after 2m is opened.
Referring to fig. 9, when the airflow blows along the width direction of the wind deflector 11, a part of the airflow winds from the ventral surface 12a to the dorsal surface 12b, and at the same time, the airflow flows from the leading edge 121 to the trailing edge 122, so that a spiral vortex wake is formed in the part of the airflow relative to the wing. Namely, the air flow is originally straight when flowing through the air deflector 11, and can form a plurality of vortex-shaped wake flows after being guided by the multi-machine wing plate 12, so that the mass and heat transfer effects are enhanced, and the heat convection capability is improved; the stroke of the airflow is reduced on the premise of not reducing the heat exchange quantity; the effect of gentle wind feeling can be realized in a slightly far range by strong convection and strong heat exchange in a range close to the air outlet.
Referring to fig. 10 to 13, the swirl strength is stronger in the range of α -15 ° to α -55 °, except that the influence range of the swirl wake is smaller when α -15 ° and α -25 °, which is not favorable for driving the rear air to rotate. When alpha is 70 degrees, the vortex condition is obviously changed, and the wing tip vortex degree is very weak. Tip vortices are preferred when α is 25 ° to 55 °.
But the effect of a on the vortex wake is not sufficiently judged by means of the streamline distribution alone. The vorticity is a physical quantity reflecting the strength of the vortex.
The vortex core length of the vortex wake is at a maximum when the angle of attack α is 15 ° and α is 25 °. However, as can be seen from the streamline distribution in fig. 10 to 13, since the incidence angle α is small, the wake flow influence range is relatively small, and thus the angle is suitable for use situations where air blowing is performed at a relatively long distance and heat exchange efficiency needs to be enhanced. The swirl distribution is close in the range of α 35 ° to α 55 °, and the greater the angle of attack α, the greater the ability to break up the incoming flow, so that the effect of converting the air into a swirl wake is considered to be the best when α is 55 °. The attack angle of alpha is 35 degrees to 55 degrees, which is suitable for the design requirements of short distance air supply and soft wind feeling. When the attack angle alpha is too large, the vertical wing plates 12 block the air duct to influence the incoming air flow, the vortex amount distribution range is reduced when the angle alpha is 60 degrees, and the vortex amount distribution is very small when the angle alpha is 70 degrees, so that the comprehensive analysis shows that vortex wake flow can not be generated when the angle alpha is more than 70 degrees.
The streamline and velocity profiles obtained by numerical simulation calculation are shown in fig. 20 and 21. The wind guiding speed of the wing plate 12 and the outlet speed of the common wind guiding are both 4 m/s. It can be seen that the wake of the wing plate 12 forms a significant vortex, the local air velocity in front of the vortex is high (maximum 5.1m/s), this region is a strong mass and heat transfer region, and the air velocity rapidly decreases behind this region, reaching a softer air velocity range shortly beyond this region.
The technical scheme of the utility model through set up wing board 12 on aviation baffle 11, the air current forms the vortex along wing board 12 trailing edge 122 when wing board 12's leading edge 121 flow direction wing board 12's trailing edge 122, and the vortex of formation enlarges gradually at wing board 12 trailing edge 122, and the vortex radius reduces gradually at follow-up operation in-process, and vortex speed to can realize passing heat rapidly, with the air current gentle change, realize no wind sense or breeze sense effect.
In the above embodiment, referring to fig. 1, fig. 2 and fig. 5, the number of the wing plates 12 may be one, and certainly, in order to achieve a better flow guiding effect, the number of the wing plates 12 is multiple, and the multiple wing plates 12 are arranged at intervals along the length direction of the air guiding plate 11. For example, the number of wing plates 12 may be 5 to 12.
In order to facilitate the arrangement of the wing plates 12 on the wind deflector 11, in another preferred embodiment, the length of the wind deflector 11 is S, the distance between two adjacent wing plates 12 is D, and the span of the wing plates 12 is L, wherein S is an integral multiple of the sum of D and L.
In wind guiding, the airflow is blown out along the width direction of the wind guiding plate 11, and when the airflow flows from the leading edge 121 to the trailing edge 122 along the back surface 12b and the ventral surface 12a, the airflow mainly at the trailing edge 122 and near the two side surfaces of the wing plate 12 forms a vortex, so that the distance between two adjacent vortices is relatively larger if the span of the wing plate 12 is longer. With continued reference to fig. 14, 15, 16 and 17, in order to generate more swirl when the airflow blows through the air deflection assembly 10, in the present embodiment, the chord length of the wing plate 12 is C, the span of the wing plate 12 is L, and C/L > 1.
In fig. 14, C/L is 2, C/L is 4 in fig. 15, C/L is 10 in fig. 16, and C/L is 3, 2, 1.5 in fig. 17, it can be seen from these three figures that when C/L is 4, the two vortices at the trailing edge of the wing plate almost contact together, so C/L continues to rise, and the two vortices will interfere with each other, thereby affecting mass transfer and subsequent heat exchange. In the embodiment, C/L is more than or equal to 1.5 and less than or equal to 4.
When the air flow blows over two adjacent wing plates 12, the tips of the two adjacent wing plates 12 (the end of the trailing edge 122) form vortices, and as the vortices flow in a direction away from the wing plates 12, the radius of the vortices increases,
in the present embodiment, referring to fig. 22 and 23, if the distance between the two wings is too close, the vortices generated by two adjacent wingtips (two tips of the trailing edge 122 of the wing plate 12) are easy to interfere with each other. If the distance is too far away, more airflow does not flow through the wing tip, and the overall vortex effect is reduced. The best effect is that the vortices generated by two adjacent wingtips are just close at a distance and do not want to intersect.
Therefore, the distance between two adjacent wing plates 12 is not small. In addition, if the distance between the two wing plates 12 is too large, the blown vortex air flow is relatively loose, which is not beneficial to mass transfer and heat exchange. The distance between two adjacent wing plates 12 is D, and D is more than or equal to 1.3L and less than or equal to 2L.
For the wing plate 12, the size should not be too large, nor too small, and if too large, the wind resistance would be larger, which would affect the air output; if too small, it may result in less swirl being formed at the trailing edge 122 of the wing plate 12. Considering the size of the air outlet of the air conditioner (the width of the air deflector is 60-120mm generally), considering the movement (opening and closing) of the air deflector, in order to prevent interference, the maximum chord length C of the wing plate 12 needs to be controlled within 80 mm. The chord length C of the wing 12 is small, which is not beneficial to the formation of the tip vortex of the wing with a large scale, so the limit minimum value is 20 mm. As the vortex is mainly generated at the wing tip, the overlong wingspan is not beneficial to the enhancement of the vortex, and the two wing tip vortexes which are too short interfere with each other and are not beneficial to the generation of the vortex.
In the present embodiment, the wing panel 12 has a span L in the range of 10mm to 50mm, preferably in the range of 25mm to 40 mm.
For wing plates 12 with a span ranging from 25mm to 40mm, 1.5 ≦ C/L ≦ 4 is satisfied. The chord length of the wing plate 12 is not too long, so based on the ratio, the chord length C of the wing plate 12 can be further controlled to be between 40mm and 60 mm.
In the above embodiment, both the columnar connector 13 and the sheet-like connector 13 are described, and in the present embodiment, the connector 13 will be further described.
For the columnar connecting pieces 13 (an embodiment of the columnar connecting pieces 13 is not shown in the figure), after the airflow passes through the plurality of columnar connecting pieces 13, each columnar connecting piece forms a pair of vortex streets and then continuously propagates forwards, and the blown airflow has a karman vortex street effect, so that the airflow can be quickly mixed with indoor air, and the heat exchange mixed flow effect is further improved. Therefore, the columnar connector 13 is arranged at a position close to the leading edge 121, and the span between the vortex street and the vortex can be enlarged in space position to avoid mutual interference of the vortex street and the vortex. In addition, the area between two adjacent scrolls is less affected by the air flow (direct blowing of air) before the radii of the two adjacent scrolls are enlarged and meet, so that if the position where the cylindrical connecting member 13 connects the back surface 12b is located at the perpendicular bisector of the wingspan, the blank area between the two adjacent scrolls can be just compensated.
Referring to fig. 2 and 3, as for the sheet-shaped connecting member 13, since the structure has a certain dividing effect on the airflow, the formation of the vortex can be greatly reduced (the vortex is formed in advance, which is not beneficial to the formation of the vortex at the rear edge 122 of the wing plate 12, and the vortex can disturb the vortex), so that the sheet-shaped connecting member 13 is arranged at a position close to the front edge 121, which can perform a rectifying effect on the airflow, and when the airflow flows through the wing plate 12, the vortex phenomenon of the subsequent airflow is greatly reduced. If the position of the sheet-like connection 13 is on the midperpendicular of the span, the radius and flow velocity of the vortex formed by the two tail tips of the trailing edge 122 of the wing plate 12 can be kept consistent, and the overall mass and heat transfer is more uniform.
Referring to fig. 19, as to the installation manner of the air deflector assembly 10 on the air conditioner, specifically, taking a floor type air conditioner indoor unit as an example, the floor type air conditioner indoor unit has an air outlet, a plurality of air deflector assemblies 10 are installed at the air outlet, the plurality of air deflector assemblies 10 are arranged at intervals along the up-down direction, and two rows of wing plates 12 adjacent to each other in the up-down direction are separated by the air deflector 11.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
