Longitudinal beam for air conditioner outdoor unit and air conditioner

Abstract

The utility model relates to the technical field of air conditioners, and discloses a longitudinal beam for an air conditioner outdoor unit and an air conditioner. The longitudinal beams are tubular. Under the condition that the structural strength of the longitudinal beam is certain, compared with a plate-shaped longitudinal beam, the longitudinal beam is tubular, the width of the longitudinal beam can be obviously reduced, and therefore the influence of the longitudinal beam on air outlet of a fan is reduced, and wind resistance is reduced. On one hand, the noise of the whole machine can be reduced by reducing the wind resistance, and on the other hand, after the wind resistance is reduced, the wind outlet efficiency of the fan is increased, and the rotating speed of the fan can be reduced under the condition that the wind outlet amount of the fan is fixed, so that the noise of the whole machine is also reduced.

Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a longitudinal beam for an outdoor unit of an air conditioner and an air conditioner. Background Art

[0002] In order to improve the energy efficiency of the air conditioner outdoor unit, increasing the air volume of the fan is one of the important means. However, when the air volume is increased, the noise of the air supply system is an important factor that needs to be considered.

[0003] In the related art, when space permits, the diameter of the fan in the outdoor unit is designed to be maximized, so that when the fan has a large outer diameter, the fan speed can be reduced, thereby achieving a large air volume and low noise of the air supply system. However, when the fan diameter is maximized, the distance between the two fans in the outdoor unit will be very close, causing the air output of the two fans to affect each other.

[0004] Therefore, the solution of simply increasing the fan diameter has the disadvantage that the air output of the fans will affect each other. How to reduce the noise of the air supply system is an urgent problem to be solved.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The disclosed embodiments provide a longitudinal beam for an outdoor unit of an air conditioner and an air conditioner to reduce the noise of an air supply system.

[0008] According to a first aspect of an embodiment of the utility model, a longitudinal beam for an outdoor unit of an air conditioner is provided, wherein the longitudinal beam is tubular.

[0009] The longitudinal beam for the outdoor unit of the air conditioner provided in the embodiment of the present disclosure, when the structural strength of the longitudinal beam is constant, is set to be tubular compared to a plate shape, which can significantly reduce the width of the longitudinal beam, thereby reducing the influence of the longitudinal beam on the air outlet of the fan and reducing wind resistance. On the one hand, the reduction of wind resistance can reduce the noise of the whole machine, and on the other hand, after the wind resistance is reduced, the air outlet efficiency of the fan is increased. When the air outlet of the fan is constant, the speed of the fan can be reduced, thereby also reducing the noise of the whole machine.

[0010] Optionally, the longitudinal beam is at least partially in the shape of a flat tube.

[0011] Compared with round tubes, flat tubes have stronger deformation resistance, that is, higher strength.

[0012] Optionally, the longitudinal beam includes: a first flat tube section corresponding to the fan setting of the outdoor unit, and in the cross section of the first flat tube section, the dimension along the air outlet direction of the fan is larger than the dimension perpendicular to the air outlet direction of the fan.

[0013] This arrangement can reduce the shielding area of ​​the air outlet by the first flat tube section and reduce the wind resistance of the fan.

[0014] Optionally, the longitudinal beam also includes: a second flat tube segment, connected to the first flat tube segment and located at at least one end of the first flat tube segment in the length direction; wherein, in the cross section of the second flat tube segment, the dimension along the wind outlet direction of the fan is smaller than the dimension perpendicular to the wind outlet direction of the fan.

[0015] The second flat tube section is staggered with the fan, so the second flat tube section has less impact on the air output, and it is more necessary to consider the second flat tube section for enhancing the strength of the longitudinal beam. The cross-sectional shape of the first flat tube section is different from the cross-sectional shape of the second flat tube section, which can further enhance the strength of the longitudinal beam.

[0016] Optionally, a dimension of the first flat tube segment perpendicular to the air outlet direction of the fan is smaller than a dimension of the second flat tube segment perpendicular to the air outlet direction of the fan.

[0017] This arrangement can reduce the wind resistance by relying on the first flat tube section with a smaller size along the direction perpendicular to the wind outlet, and can also increase the strength of the longitudinal beam by relying on the second flat tube section with a larger size along the direction perpendicular to the wind outlet.

[0018] Optionally, a smooth transition is adopted at the connection between the first flat tube segment and the second flat tube segment.

[0019] This arrangement can enhance the strength of the longitudinal beam on the one hand, and reduce the wind resistance caused by the longitudinal beam on the other hand.

[0020] Optionally, the longitudinal beam further includes: a transition pipe section connected between the first flat pipe section and the second flat pipe section, and a cross section of the transition pipe section is circular.

[0021] This arrangement enables a smooth transition from the second flat tube section to the first flat tube section, rather than a sudden change, thereby avoiding an increase in the fan's air outlet resistance caused by the sudden change.

[0022] Optionally, the longitudinal beam also includes: a connecting pipe section, which is arranged at the end of the second flat pipe section away from the first flat pipe section, suitable for connecting to the first crossbeam or the second crossbeam of the outdoor unit, and the ratio of the dimension of the connecting pipe section along the air outlet direction of the fan to the dimension perpendicular to the air outlet direction of the fan is smaller than the ratio of the dimension of the second flat pipe section along the air outlet direction of the fan to the dimension perpendicular to the air outlet direction of the fan.

[0023] The flattening degree of the connecting pipe section is greater than that of the second flat pipe section, so as to facilitate the connection of the connecting pipe section with the first cross beam or the second cross beam.

[0024] Optionally, the longitudinal beam is a hollow structure; or, part of the longitudinal beam is a hollow structure and part of it is a solid structure; or, the longitudinal beam is a solid structure.

[0025] The hollow structure can reduce the weight of the longitudinal beam, and the solid structure can enhance the strength of the longitudinal beam.

[0026] According to a second aspect of an embodiment of the utility model, an air conditioner is provided, including an outdoor unit, the outdoor unit including: a shell provided with an air outlet; a fan arranged in the shell; a cover body, covering the air outlet, including a first cross beam, a second cross beam, and a longitudinal beam for the outdoor unit of the air conditioner as described in any one of the above embodiments, the longitudinal beam being connected between the first cross beam and the second cross beam.

[0027] The air conditioner provided in the second aspect of the embodiment of the utility model includes the longitudinal beam for the outdoor unit of the air conditioner described in any one of the above embodiments, and thus has all the beneficial effects of the longitudinal beam for the outdoor unit of the air conditioner described in any one of the above embodiments, which will not be repeated here.

[0080] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0081] Embodiment 1:

[0082] Combination Figure 1-8 , Figure 16-41 As shown, an embodiment of the present disclosure provides a cover body 1 for an air-conditioning outdoor unit 100 , and the cover body 1 is suitable for covering an air outlet 21 of the outdoor unit 100 .

[0083] The outdoor unit 100 includes a housing 2, which is provided with an air inlet and an air outlet 21. The outdoor unit 100 also includes a compressor, an outdoor heat exchanger and a fan 6, which are all located in the housing 2. The fan 6 drives air to enter the housing 2 from the air inlet, exchange heat with the outdoor heat exchanger, and then blow out from the air outlet 21.

[0084] The cover body 1 includes a frame 11 and a protection net 12 .

[0085] The frame 11 encloses an installation space; the protective net 12 is arranged in the installation space, and the cover is arranged on the fan 6, and the protective net 12 is a mesh structure in which a horizontal grille and a vertical grille intersect; wherein, the inner edge 1116 of the frame 11 is provided with an opening groove 1111, and the inner edge 1116 of the frame 11 refers to the edge of the frame 11 facing the installation space.

[0086] The opening slot 1111 can reduce the area of ​​the inner edge 1116 of the frame 11, thereby reducing the shielding area of ​​the frame 11 on the air outlet 21, reducing the wind resistance of the fan 6, and reducing the noise of the outdoor unit 100. Moreover, after the wind resistance is reduced, when the air volume of the fan 6 is constant, the rotation speed of the fan 6 can be reduced, further reducing the noise of the outdoor unit 100.

[0087] Compared with other structures on the frame 11, the inner edge 1116 of the frame 11 is closer to the fan 6 and has the greatest impact on the air discharge of the fan 6. Therefore, setting the opening slot 1111 on the inner edge 1116 has a more significant effect on reducing noise than setting the opening slot 1111 on other positions on the frame 11 except the inner edge 1116. Moreover, when the size and shape of the opening slot 1111 are constant, compared with setting the opening slot 1111 in the middle of the frame 11, setting it on the edge of the frame 11 causes less loss to the strength of the frame 11. Therefore, in the present application, setting the opening slot 1111 on the inner edge 1116 of the frame 11 can reduce the air discharge resistance of the air outlet 21 and reduce the noise of the whole machine while ensuring the structural strength of the frame 11.

[0088] Optionally, the frame 11 includes a first cross beam 111 , a second cross beam 112 and a longitudinal beam 113 .

[0089] The second cross beam 112 is disposed opposite to the first cross beam 111 , and the protection net 12 is located between the first cross beam 111 and the second cross beam 112 .

[0090] The number of fans 6 is multiple, such as Fig.28 As shown, there are two fans 6. The two fans 6 are arranged in sequence along the length direction of the first crossbeam 111 and the second crossbeam 112. Figure 1 and Figure 2 As shown, the longitudinal beam 113 is disposed between the first cross beam 111 and the second cross beam 112 to enhance the overall strength of the frame 11 .

[0091] The number of the protection nets 12 is equal to and corresponds to the number of the fans 6 , and the longitudinal beam 113 is located between two adjacent protection nets 12 .

[0092] The inner edge of the frame includes the inner edge 1116 of the first cross beam 111, the inner edge 1116 of the second cross beam 112, and the inner edge 1116 of the longitudinal beam 113. At least one of the inner edge 1116 of the first cross beam 111, the inner edge 1116 of the second cross beam 112, and the inner edge 1116 of the longitudinal beam 113 is provided with an opening groove 1111. Figure 2 As shown, the inner edge 1116 of the first cross beam 111 , the inner edge 1116 of the second cross beam 112 , and the inner edge 1116 of the longitudinal beam 113 are all provided with an open groove 1111 .

[0093] The inner edge 1116 of the first cross beam 111, the inner edge 1116 of the second cross beam 112 and the inner edge 1116 of the longitudinal beam 113 will all block the air outlet of the fan 6. Therefore, an open groove 1111 is provided on at least one of the inner edge 1116 of the first cross beam 111, the inner edge 1116 of the second cross beam 112 and the inner edge 1116 of the longitudinal beam 113, which will reduce the air outlet resistance of the fan 6.

[0094] Alternatively, if Fig.38 As shown, the outdoor unit 100 further includes an air guide ring 5, which is located in the housing 2, and a fan 6 is located in the air guide ring 5. In the orthographic projection of the frame 11 on the air guide ring 5, the opening slot 1111 is at least partially located inside the air guide ring 5.

[0095] In the orthographic projection of the frame 11 on the plane perpendicular to the axis of the air guide ring 5, the portion of the frame 11 located inside the air guide ring 5 blocks the air flow more seriously, and arranging the opening slot 1111 in this portion has a more significant effect on reducing the wind resistance of the fan 6. When the opening slot 1111 is arranged in this portion, in the orthographic projection of the frame 11 on the air guide ring 5, at least a portion of the opening slot 1111 is located inside the air guide ring 5.

[0096] The number of the first cross beams 111 and the second cross beams 112 are both multiple, and the number is equal to the number of the fans 6. The multiple first cross beams 111 are connected and arranged in sequence along the arrangement direction of the multiple fans 6, and the multiple second cross beams 112 are connected and arranged in sequence along the arrangement direction of the multiple fans 6. Figure 2 In the embodiment, the number of the first cross beam and the number of the second cross beam are both two, which are equal to and correspond to the number of the fans.

[0097] A first cross beam 111 , a second cross beam 112 and a longitudinal beam 113 enclose an installation space, and a protection net 12 is located in the installation space.

[0098] The plurality of first beams 111 are connected to each other, or the plurality of first beams 111 are an integrated structure.

[0099] The plurality of second beams 112 are connected to each other, or the plurality of second beams 112 are an integrated structure.

[0100] The opening slot 1111 is arranged at the middle of the length direction of the first cross beam 111, the second cross beam 112, and the longitudinal beam 113, and is arranged corresponding to the axis of the fan 6. The middle of the length direction of the first cross beam 111, the second cross beam 112, and the longitudinal beam 113 corresponds to the axis of the fan 6, and the wind resistance caused there is relatively large. Therefore, the opening slot 1111 is arranged there, which has a significant effect on reducing the wind resistance.

[0101] The opening slot 1111 can be in various shapes, for example Figure 3 It is shown as a long strip, and the length direction of the long strip is the length direction of the first cross beam 111 where it is located, or the length direction of the first cross beam 111 where it is located, or the length direction of the longitudinal beam 113 where it is located.

[0102] When setting the shape and size of the opening slot 1111 , the wind resistance and the structural strength of the frame 11 need to be comprehensively considered.

[0103] Optionally, a reinforcement structure is provided on the bottom wall of the opening groove 1111 to enhance the strength of the frame 11 and avoid a significant impact on the strength of the frame 11 due to the setting of the opening groove 1111 .

[0104] Optionally, the reinforcement structure includes reinforcement ribs, such as Figure 3 ,like Fig.18 and Fig. 20 As shown, there are multiple reinforcing ribs 1112, and the multiple reinforcing ribs 1112 are arranged in sequence along the length direction of the opening groove 1111 to form a zigzag shape.

[0105] Compared with setting one reinforcing rib 1112, a plurality of reinforcing ribs 1112 are set in this solution. Under the premise of satisfying the structural strength of the frame 11, the size of each reinforcing rib 1112 can be reduced to avoid a significant impact of the reinforcing rib 1112 on the air outlet.

[0106] The ratio of the length of each reinforcing rib 1112 to the length of the opening slot 1111 is greater than or equal to one third and less than or equal to three quarters, achieving a relative balance between reducing wind resistance and increasing the strength of the frame 11 .

[0107] The reinforcing rib 1112 may be rectangular, triangular or any other shape, all of which are within the protection scope of the present application.

[0108] In a specific embodiment, the reinforcing ribs 1112 extend toward the protective net 12. This can not only enhance the strength of the frame 11, but also reduce the wind resistance caused by the reinforcing ribs 1112 as little as possible.

[0109] like Fig.18 and Fig. 20 As shown, the reinforcing rib 1112 is arranged perpendicular to the bottom wall of the opening groove 1111 where it is located.

[0110] In another specific embodiment, the reinforcing rib 1112 is bent toward the inside of the shell 2 to form the reinforcing rib 1112 .

[0111] Compared with the reinforcing ribs 1112 extending toward the protective net 12, the reinforcing ribs 1112 bending toward the inside of the shell 2 can further enhance the strength of the frame 11, and reduce the shielding of the wind from the fan 6 by the reinforcing ribs 1112, further reducing wind resistance.

[0112] The number of reinforcing ribs 1112 may be one or more. Figure 3 As shown, when there are multiple reinforcing ribs 1112 , the multiple reinforcing ribs 1112 are arranged in sequence along the length direction of the opening groove 1111 .

[0113] like Figure 7 and Figure 8 As shown, the number of reinforcing ribs 1112 is one, one end of the reinforcing rib 1112 in the length direction is connected to one side wall of the opening groove 1111, and the other end of the reinforcing rib 1112 in the length direction is connected to the other side wall of the opening groove 1111. The connection between the reinforcing rib 1112 and the side wall of the opening groove 1111 forms an arc transition (such as Figure 7 Compared with the reinforcing rib 1112 being perpendicular to the groove sidewall of the opening groove 1111, the arc transition can further enhance the strength of the frame 11. The arc transition can be performed by using one arc or multiple arcs connected end to end, and the multiple arcs are sequentially arranged along the direction from the reinforcing rib 1112 to the groove sidewall of the opening groove 1111.

[0114] The provision of the reinforcing ribs 1112 allows an air outlet gap to be formed between the frame 11 and the protective net 12 , thereby reducing the shielding of the air outlet of the fan 6 by the frame 11 and reducing the air outlet resistance. In addition, the reinforcing ribs 1112 can also enhance the strength of the frame 11 .

[0115] The reinforcing rib 1112 may also be bent in a direction away from the interior of the housing 2. Fig.26 In the embodiment, the direction away from the interior of the housing 2 is upward.

[0116] Optionally, one end of the reinforcing rib 1112 facing away from the bottom wall of the opening groove 1111 is located outside the inner edge 1116 of the frame 11 where the reinforcing rib 1112 is located.

[0117] When the reinforcing rib 1112 is provided on the first cross beam 111, one end of the reinforcing rib 1112 which turns away from the bottom wall of the opening groove 1111 is located on the outside of the inner edge 1116 of the first cross beam 111, that is, the reinforcing rib 1112 does not extend to the inner edge 1116 of the first cross beam 111; when the reinforcing rib 1112 is provided on the second cross beam 112, one end of the reinforcing rib 1112 which turns away from the bottom wall of the opening groove 1111 is located on the outside of the inner edge 1116 of the second cross beam 112, that is, the reinforcing rib 1112 does not extend to the inner edge 1116 of the second cross beam 112; when the reinforcing rib 1112 is provided on the longitudinal beam 113, one end of the reinforcing rib 1112 which turns away from the bottom wall of the opening groove 1111 is located on the outside of the inner edge 1116 of the longitudinal beam 113, that is, the reinforcing rib 1112 does not extend to the inner edge 1116 of the longitudinal beam 113. The direction close to the axis of the fan 6 is the inner side, and the direction away from the axis of the fan 6 is the outer side, so as to reduce the wind resistance caused by the reinforcing ribs 1112.

[0118] like Figure 4 As shown, the longitudinal beam 113 includes a first connecting section 1131, a second connecting section 1132 and a third connecting section 1133, and the first connecting section 1131, the second connecting section 1132 and the third connecting section 1133 are sequentially arranged along the width direction of the longitudinal beam 113. The second connecting section 1132 is lower than the first connecting section 1131 and the third connecting section 1133. The longitudinal beam 113 also includes a first transition section 1134 and a second transition section 1135, the first transition section 1134 is connected between the first connecting section 1131 and the second connecting section 1132, and the second transition section 1135 is connected between the second connecting section 1132 and the third connecting section 1133.

[0119] The first transition section 1134 and the second transition section 1135 are both arranged to be inclined, and can play a role in guiding the airflow of the fan 6 at their positions to be discharged from the air outlet 21.

[0120] The second connecting section 1132 is provided with a through hole 1136 , which is formed by a stretching process. On one hand, the through hole 1136 can reduce wind resistance, and on the other hand, the through hole 1136 can enhance the structural strength of the longitudinal beam 113 .

[0121] The through hole 1136 is in the shape of a long strip, and the extending direction of the through hole 1136 is consistent with the length direction of the longitudinal beam 113. There are multiple through holes 1136, and the multiple through holes 1136 are sequentially arranged along the length direction of the longitudinal beam 113. The through hole 1136 can also be a hole of other shapes, and the number of the through hole 1136 can also be one, all within the protection scope of the present application.

[0122] Optionally, the frame 11 is provided with a guide structure to guide the fan 6 to discharge air toward the air outlet 21 .

[0123] The guide structure can guide the air from the fan 6 to flow smoothly from the air outlet 21, reducing the wind resistance of the air from the fan 6, thereby reducing the wind resistance and reducing the wind noise. Moreover, after the wind resistance is reduced, the air supply efficiency of the fan 6 becomes higher, thereby reducing the rotation speed of the fan 6 and further reducing the wind noise.

[0124] Optionally, the flow guiding structure comprises a flange.

[0125] The inner edge 1116 of the frame 11 is bent toward the inside of the shell 2 to form a flange, so that the flange has a flow-guiding function and can guide the air outlet of the fan 6 to flow out smoothly from the air outlet 21 .

[0126] The flange is bent with respect to the inner edge 1116 of the frame 11, and the flange may be perpendicular to the inner edge 1116 of the frame 11, or may not be perpendicular to the inner edge 1116 of the frame 11. For example, in the opposite direction of the air outlet of the fan 6, the flange is inclined in a direction away from the axis of the fan 6, such as Figures 5 to 7 As shown, the obstruction of the flange to the air outlet of the fan 6 can be reduced, and the guiding effect of the flange on the air outlet of the fan 6 can be enhanced.

[0127] The inner edge 1116 of the frame 11 includes a first inner edge 1117, which is arranged corresponding to the air guide ring 5. The first inner edge 1117 is bent toward the inside of the shell 2 to form a first flange 1114, wherein the flange includes the first flange 1114, and at this time the first flange 1114 can be a reinforcing rib 1112 bent toward the inside of the shell 2.

[0128] The inner edge 1116 of the frame 11 includes a second inner edge 1118 , which is staggered with the air guide ring 5 . The second inner edge 1118 is bent toward the inside of the shell 2 to form a second flange 1115 , wherein the flange includes the second flange 1115 .

[0129] When the flange is provided on the first crossbeam 111, the first inner edge 1117 and the second inner edge 1118 are sequentially arranged in the length direction of the first crossbeam 111, the first inner edge 1117 is located in the middle of the length direction of the first crossbeam 111, and the second inner edge 1118 is located at the end of the length direction of the first crossbeam 111. When the flange is provided on the second crossbeam 112, the first inner edge 1117 and the second inner edge 1118 are sequentially arranged in the length direction of the second crossbeam 112, the first inner edge 1117 is located in the middle of the length direction of the second crossbeam 112, and the second inner edge 1118 is located at the end of the length direction of the second crossbeam 112. When the flange is provided on the longitudinal beam 113, the first inner edge 1117 and the second inner edge 1118 are sequentially arranged in the length direction of the longitudinal beam 113, the first inner edge 1117 is located in the middle of the length direction of the first crossbeam 111, and the second inner edge 1118 is located at the end of the length direction of the longitudinal beam 113.

[0130] The first flange 1114 and the second flange 1115 are both bent toward the inside of the shell 2 . Therefore, the first flange 1114 and the second flange 1115 both have a guiding effect on the air outlet of the fan 6 and can also enhance the structural strength of the frame 11 .

[0131] There are multiple flanges, and the multiple flanges are arranged in sequence along the length direction of the frame 11 at their positions.

[0132] When the flange is provided on the first crossbeam 111, multiple flanges are provided in sequence along the length direction of the first crossbeam 111. When the flange is provided on the second crossbeam 112, multiple flanges are provided in sequence along the length direction of the second crossbeam 112. When the flange is provided on the longitudinal beam 113, multiple flanges are provided in sequence along the length direction of the longitudinal beam 113.

[0133] Providing a plurality of flanges can reduce the shielding of the air outlet 21 by the flanges and increase the air outlet area of ​​the air outlet 21 .

[0134] The number of flanges can also be one, such as Figure 7 The number of the first flange 1114 is one, and the first flange 1114 and the second flange 1115 are an integrated structure. The provision of one flange can greatly increase the strength of the frame 11 .

[0135] In practical applications, the shape, size and number of the flanges can be determined by comprehensively considering the requirements for the strength of the frame 11 and the requirements for the wind resistance of the fan 6 .

[0136] The number of the first flanges 1114 is one or more.

[0137] The first inner edge 1117 is provided with an open groove 1111 , and the first flange 1114 is located at the bottom wall of the open groove 1111 and at the outer side of the second flange 1115 .

[0138] Compared with the second inner edge 1118, the first inner edge 1117 is set corresponding to the air guide ring 5, that is, it is set corresponding to the axis of the fan 6, and the wind resistance caused to the wind of the fan 6 is greater. Therefore, compared with the role of enhancing the strength of the frame 11, the first flange 1114 should achieve the role of reducing wind resistance. The second flange 1115 has a smaller effect on wind resistance. Therefore, compared with reducing wind resistance, the second flange 1115 should achieve the role of enhancing the strength of the frame 11. Therefore, the first flange 1114 is set to be located outside the second flange 1115, wherein the direction close to the middle of the shell 2 is the inside, and the direction away from the middle of the shell 2 is the outside.

[0139] Along the air outlet direction of the fan 6, the wall surface of the frame 11 facing the fan 6 is inclined toward the middle of the protective net 12 to form an inclined surface, and the guide structure includes the inclined surface.

[0140] like Fig.26 In the embodiment, the air outlet mode of the outdoor unit 100 is the top outlet mode, and the frame 11 is arranged above the fan 6. The wall surface of the frame 11 facing the fan 6 is the lower wall surface of the frame 11.

[0141] The air outlet of the fan 6 can flow along the inclined surface, so the inclined surface has a guiding effect on the air outlet of the fan 6.

[0142] The inclined surface can be a flat surface or a curved surface.

[0143] Optionally, the inclined surface is arranged corresponding to the air guide ring 5 .

[0144] At least one of the inner edge 1116 of the first cross beam 111 , the inner edge 1116 of the second cross beam 112 , and the longitudinal beam 113 is provided with a flow guiding structure.

[0145] A guide structure is provided on at least one of the inner edge 1116 of the first cross beam 111 , the inner edge 1116 of the second cross beam 112 and the longitudinal beam 113 , all of which can guide the air discharged by the fan 6 , thereby reducing wind resistance.

[0146] like Fig.33 and Fig.38 As shown, the outdoor unit 100 further includes a lower beam 3. There are two lower beams 3, one of which is located below the first cross beam 111, and the other is located below the second cross beam 112.

[0147] The lower beam 3 is used to install the air guide ring 5 and the fan 6. The fan 6 includes a blade 61 and a motor 62, and the motor is drivingly connected to the blade 61 to drive the blade 61 to rotate. The outdoor unit 100 also includes a motor bracket 34, the motor is arranged on the motor bracket 34, and one end of the motor bracket 34 is supported on a lower beam 3, and the other end of the motor bracket 34 is supported on another lower beam 3.

[0148] Therefore, the lower beam 3 realizes the fixation of the air guide ring 5 and the fan 6 .

[0149] like Fig.34 As shown, the lower beam 3 includes a first beam section 31 , and the first beam section 31 is arranged on the inner side of the air guide ring 5 ; wherein the first beam section 31 is provided with an avoidance groove 311 for avoiding the blades 61 of the fan 6 .

[0150] The first beam section 31 is provided with an avoidance groove 311 for avoiding the blades 61 of the fan 6, so that the radial size of the blades 61 of the fan 6 can be maximized. Moreover, compared with the air guide ring 5 provided on the inner side of the first beam section 31, the air guide ring 5 is located on the outer side of the first beam section 31, so that the air guide ring 5 also has a larger inner diameter. Therefore, the air guide ring 5 can accommodate the fan 6 blades 61 with maximized radial size, ensuring that the fan 6 can be installed in the air guide ring 5. Moreover, the setting of the avoidance groove 311 can reduce the obstruction of the first beam section 31 to the air outlet of the fan 6 and reduce the wind resistance of the air outlet. Therefore, when the air outlet of the fan 6 is constant, the rotation speed of the fan 6 can be reduced, and the air supply noise of the fan 6 can be reduced.

[0151] Optionally, the outer surface of the first beam segment 31 includes a first outer surface 3112 and a second outer surface 3113 .

[0152] like Fig.37 As shown, the first outer surface 3112 and the second outer surface 3113 are arranged opposite to each other, and along the air outlet direction of the fan 6, the first outer surface 3112 and the second outer surface 3113 are arranged in sequence, and the avoidance groove 311 is arranged on the second outer surface 3113.

[0153] Taking the outdoor unit 100 as a top-outlet outdoor unit 100 as an example, the first outer surface 3112 is the lower surface of the first beam section 31 , and the second outer surface 3113 is the upper surface of the first beam section 31 .

[0154] The lower beam 3 includes a first plate surface 313 and a second plate surface 314. The first plate surface 313 extends along the axis direction of the fan 6, and the second plate surface 314 extends in a direction perpendicular to the axis direction of the fan 6. The first plate surface 313 and the second plate surface 314 are connected and a fold is formed at the connection. The motor bracket 34 is placed on the second plate surface 314, that is, the second plate surface 314 supports the motor bracket 34.

[0155] The second outer surface 3113 is the upper surface of the first plate surface 313 , and the first outer surface 3112 is the bottom wall surface of the second plate surface 314 . There is no interference between the second plate surface 314 and the blades 61 of the fan 6 , so the avoidance groove 311 is provided on the second outer surface 3113 .

[0156] Optionally, the lower beam 3 further includes a second beam section 32 , which is connected to at least one end of the first beam section 31 in the length direction and is suitable for being arranged on the outside of the air guide ring 5 .

[0157] The second beam section 32 is arranged outside the air guide ring 5 to facilitate the connection between the second beam section 32 and the shell 2 , thereby achieving the fixation of the lower beam 3 on the shell 2 .

[0158] Optionally, an arc-shaped transition is adopted at the connection between the avoidance groove 311 and the second beam section 32 .

[0159] The upper surface of the second beam section 32 is higher than the bottom wall of the avoidance groove 311, and the upper surface of the second beam section 32 and the bottom wall of the groove adopt an arc-shaped transition. On the one hand, the smoothness of the connection between the avoidance groove 311 and the second beam section 32 is enhanced, which can reduce the wind resistance of the lower beam 3 to the air outlet of the fan 6. On the other hand, it can enhance the structural strength of the lower beam 3 to ensure that the lower beam 3 meets the structural strength requirements.

[0160] Optionally, the lower beam 3 is provided with a reinforcing structure to enhance the strength of the lower beam 3 and avoid the strength of the lower beam 3 being affected by the setting of the avoidance groove 311 .

[0161] Optionally, the reinforcement structure includes reinforcement ribs provided on the first beam section 31 .

[0162] The avoidance groove 311 is provided on the first beam section 31, which will affect the strength of the first beam section 31. Therefore, the first beam section 31 needs to be strengthened, or in other words, the strengthening structure provided on the first beam section 31 has a more obvious effect on improving the strength of the entire lower beam 3.

[0163] like Fig.37 As shown, the reinforcing ribs include a first reinforcing rib 3111 , which is disposed on the bottom wall of the avoidance groove 311 and bent toward the inner side of the air guide ring 5 .

[0164] It can be understood that the first reinforcing rib 3111 formed by the bottom wall of the avoidance groove 311 being bent toward the inner side of the air guide ring 5 is used to enhance the strength of the avoidance groove 311 .

[0165] The first reinforcing rib 3111 is located on the outer side of the second plate surface 314 to avoid interference between the first reinforcing rib 3111 and the fan blade.

[0166] like Fig.35 As shown, the reinforcement structure may also be provided on the second beam section 32 , for example, the reinforcement structure includes a second reinforcement rib 312 formed by inward bending of the upper surface of the second beam section 32 .

[0167] The reinforcing ribs include second reinforcing ribs 312 . The second reinforcing ribs 312 are arranged corresponding to the avoidance grooves 311 . The second reinforcing ribs 312 and the avoidance grooves 311 are arranged in sequence along the air outlet direction of the fan 6 .

[0168] For example Fig.35As shown, the second reinforcement rib 312 is arranged directly below the avoidance groove 311. The second reinforcement rib 312 is formed by partially punching the first beam section 31 inwardly as a whole, or it can be formed by protruding the inner wall surface of the second beam section 32.

[0169] The orthographic projection of the axis of the fan 6 on the lower beam 3 is located at the first beam section 31 , and the first beam section 31 is arranged corresponding to the axis of the fan 6 .

[0170] The second beam section 32 is staggered with the axis of the fan 6 , and the second beam section 32 itself will not interfere with the blades 61 of the fan 6 . Therefore, there is no need to provide the avoidance groove 311 in the second beam section 32 .

[0171] like Fig.31 and Fig.32 As shown, the outdoor unit 100 further includes an electric control box 4, in which electric control components such as a computer board are arranged. The lower beam 3 is provided with a hook 33 for hooking the electric control box 4.

[0172] The hook 33 is arranged on the outer wall surface of the lower beam 3, wherein the surface away from the middle of the housing 2 is the outer wall surface. The electric control box 4 is provided with a hole 41, and the hook 33 is inserted into the hole 41 to achieve hooking of the electric control box 4.

[0173] There are multiple hooks 33 , and the multiple hooks 33 are arranged in sequence along the length direction of the lower beam 3 .

[0174] The electric control box 4 is also connected to the lower beam 3 by screws.

[0175] During assembly, the hook 33 is first inserted into the hole 41, and no hand support is required. The electric control box 4 can be pre-installed before the whole machine is assembled online. After hanging on the lower beam 3, the wire harness inside the electric control box 4 can be sorted, which speeds up production efficiency and reduces the labor intensity of workers. Then the electric control box 4 and the lower beam 3 are connected by screws to enhance the fixing firmness of the electric control box 4 and the lower beam 3.

[0176] The air guide ring 5 includes a first air guide section 51 and a second air guide section 52. The cross section of the second air guide section 52 is annular. The first air guide section 51 is connected to the second air guide section 52 and the first air guide section 51 and the second air guide section 52 are sequentially arranged along the air outlet direction of the fan 6. The cross section of the first air guide section 51 is non-annular, for example, rectangular or approximately rectangular.

[0177] The inner wall surface of the first air guiding section 51 protrudes outward to form a protrusion 5121 to prevent the blades 61 of the fan 6 from interfering with the first air guiding section 51 .

[0178] The protrusion 5121 is provided to increase the distance between the protrusion 5121 on the inner wall surface of the first air guide section 51 and the axis of the air guide ring 5, thereby avoiding interference between the blades 61 of the fan 6 and the first air guide section 51. In this way, the diameter of the blades 61 of the fan 6 can be increased, and the diameter of the blades 61 of the fan 6 can be maximized. In this way, when the air output of the fan 6 is constant, the rotation speed of the fan 6 can be reduced, and the air supply noise of the fan 6 can be reduced.

[0179] like Figures 38 to 41 As shown, for the outdoor unit 100 with top air discharge, the first air guide section 51 is arranged below the second air guide section 52. The protrusion 5121 is mainly used to prevent the tip of the blade 61 from interfering with the first air guide section 51 during rotation.

[0180] There are multiple fans 6, and the number of the air guide rings 5 ​​is equal to and corresponds to the number of the fans 6. In other words, one fan 6 is arranged in one air guide ring 5, and one fan 6 is located in one air guide ring 5.

[0181] The first wind guiding section 51 includes a first wind guiding wall 511 and a second wind guiding wall 512 .

[0182] The first wind guide wall 511 is arranged opposite to the adjacent fan 6; the second wind guide wall 512 and the first wind guide wall 511 are arranged in sequence along the circumference of the first wind guide section 51, and the second wind guide wall 512 is connected to the first wind guide wall 511 and a fold is formed at the connection; the protrusion 5121 is arranged on the second wind guide wall 512.

[0183] For the convenience of description, two of the plurality of fans 6 are named as the first fan 6 and the second fan 6, and corresponding two of the plurality of air guide rings 5 ​​are named as the first air guide ring 5 and the second air guide ring 5. The first fan 6 is located in the first air guide ring 5, and the second fan 6 is located in the second air guide ring 5.

[0184] The first air guide wall 511 of the first air guide circle 5 is arranged opposite to the second fan 6 , and the second air guide wall 512 of the second air guide circle 5 is arranged opposite to the first fan 6 .

[0185] There are two second air guide walls 512 , which are arranged opposite to each other; there are two first air guide walls 511 , which are arranged opposite to each other. The two first air guide walls 511 and the two second air guide walls 512 together form the first air guide section 51 .

[0186] The size of the outdoor unit 100 in the direction of the line connecting the two first air guide walls 511 (the length direction of the outdoor unit 100) is relatively large, and the first air guide wall 511 is relatively far from the axis of the air guide ring 5 where it is located, so it will not interfere with the blade 61. The size of the outdoor unit 100 in the direction of the line connecting the two second air guide walls 512 (the width direction of the outdoor unit 100) is relatively small, resulting in a relatively small distance between the axis of the second air guide wall 512 and the air guide ring 5. Therefore, the size of the blade 61 is mainly limited by the distance between the axis of the second air guide wall 512 and the air guide ring 5.

[0187] The raised portion 5121 is disposed on the second wind guide wall 512 , which increases the distance between the second wind guide wall 512 and the axis of the wind guide ring 5 , thereby increasing the diameter of the blade 61 .

[0188] The raised portion 5121 is disposed in the middle of the second air guide wall 512 in the length direction, that is, the raised portion 5121 is disposed corresponding to the axis of the fan 6, wherein the length direction is Fig.28 The middle direction is the direction indicated by the arrow N, and the width direction is the direction indicated by the arrow M.

[0189] The distance between the middle part of the second air guide wall 512 in the length direction and the axis of the air guide ring 5 is smaller than the distance between the end part of the second air guide wall 512 in the length direction and the axis of the air guide ring 5. Therefore, the middle part of the second air guide wall 512 in the length direction is more likely to interfere with the blade 61. Therefore, the protrusion 5121 is arranged in the middle part of the second air guide wall 512 in the length direction.

[0190] It is understandable that the protrusion 5121 may also extend to the end of the second air guide wall 512 in the length direction.

[0191] Alternatively, if Fig.41 As shown, in the orthographic projection of the air guide ring 5 on the preset plane, the inner surface of the protrusion 5121 is tangent to the inner surface of the second air guide segment 52, wherein the preset plane is perpendicular to the axis of the air guide ring 5, wherein the direction close to the axis of the air guide ring 5 (i.e. the axis of the fan 6) is inner, and the direction away from the axis of the air guide ring 5 (i.e. the axis of the fan 6) is outer.

[0192] The distance between the inner surface of the protrusion 5121 and the axis of the air guide ring 5 is equal to half of the inner diameter of the second air guide section 52 .

[0193] If the distance between the inner surface of the raised portion 5121 and the axis of the air guide ring 5 is less than half of the inner diameter of the second air guide segment 52, the raised portion 5121 will still limit the size of the blade 61, so that the size of the blade 61 cannot reach the maximum diameter of the blade 61 that can be accommodated by the first air guide segment 51 or the first air guide wall 511; if the distance between the inner surface of the raised portion 5121 and the axis of the air guide ring 5 is greater than half of the inner diameter of the second air guide segment 52, the raised portion 5121 will protrude outward too large, causing the size of the outdoor unit 100 in the width direction to be too large.

[0194] Therefore, setting the distance between the inner surface of the protrusion 5121 and the axis of the air guide ring 5 equal to half the inner diameter of the second air guide section 52 can maximize the diameter of the blade 61 without causing the width dimension of the outdoor unit 100 to be too large.

[0195] In the orthographic projection of the air guide ring 5 on the preset plane, the outer surface of the protrusion 5121 is tangent to the outer surface of the second air guide section 52 .

[0196] If the distance between the outer surface of the raised portion 5121 and the axis of the air guide ring 5 is less than half of the outer diameter of the second air guide segment 52, the raised portion 5121 will still limit the size of the blade 61, so that the size of the blade 61 cannot reach the maximum diameter of the blade 61 that can be accommodated by the first air guide segment 51 or the first air guide wall 511; if the distance between the outer surface of the raised portion 5121 and the axis of the air guide ring 5 is greater than half of the outer diameter of the second air guide segment 52, the raised portion 5121 will protrude outward too large, causing the size of the outdoor unit 100 in the width direction to be too large.

[0197] Therefore, setting the distance between the outer surface of the protrusion 5121 and the axis of the air guide ring 5 equal to half the outer diameter of the second air guide section 52 can maximize the diameter of the blade 61 without causing the width dimension of the outdoor unit 100 to be too large.

[0198] The protrusion 5121 is close to one end of the second air guide section 52 (such as Fig.38 The upper end of the middle protrusion 5121 is directly connected to the second air guiding section 52.

[0199] Optionally, in the orthographic projection of the air guide ring 5 on the preset plane, the outer surface of the first air guide wall 511 is tangent to the outer surface of the second air guide segment 52 , and the inner surface of the first air guide wall 511 is tangent to the inner surface of the second air guide segment 52 .

[0200] like Fig.40 As shown, the protrusion 5121 includes a first connecting arm 5122 , a second connecting arm 5123 and a protruding arm 5124 .

[0201] One end of the first connecting arm 5122 is connected to the first wind guiding section 51 ; one end of the second connecting arm 5123 is connected to the first wind guiding section 51 . The protruding arm 5124 is connected between the other end of the first connecting arm 5122 and the other end of the second connecting arm 5123 .

[0202] The protruding arm 5124 is in a planar shape, and the planar structure is easy to shape, which reduces the processing cost of the air guide ring 5. The plane is parallel to the axis of the air guide ring 5, so that the protruding arm 5124 does not interfere with the blade 61 at any place.

[0203] It is understandable that the protruding arm 5124 may also be in other shapes, for example, the protruding arm 5124 is arc-shaped, wherein the center of the arc is located at the axis of the air guide ring 5.

[0204] The outdoor unit 100 further includes a lower beam 3, which is arranged opposite to the second air guide wall 512. The air guide ring 5 is arranged on the lower beam 3, and the air guide ring 5 is fixed by the lower beam 3. The first air guide section 51 is provided with a notch 5125, and the lower beam 3 passes through the notch 5125, so that the lower beam 3 is partially located inside the first air guide section 51 and partially located outside the first air guide section 51, or in other words, the first air guide section 51 is partially located inside the lower beam 3 and partially located outside the lower beam 3, so as to avoid interference between the lower beam 3 and the air guide ring 5. The direction close to the axis of the air guide ring 5 is the inside, and the direction away from the axis of the air guide ring 5 is the outside.

[0205] The second air guiding wall 512 is provided with a notch 5125 . Part of the second air guiding wall 512 is located on the inner side of the lower beam 3 , and part of the second air guiding wall 512 is located on the outer side of the lower beam 3 .

[0206] The portion of the lower beam 3 located inside the first air guiding section 51 is provided with an avoidance groove 311 , and the avoidance groove 311 is arranged corresponding to the protrusion 5121 , that is, the avoidance groove 311 and the protrusion 5121 are arranged in sequence along the radial direction of the air guiding ring 5 .

[0207] The avoidance groove 311 and the raised portion 5121 are provided in correspondence, so as to avoid that the diameter of the blade 61 cannot be maximized due to the interference between the lower beam 3 and the blade 61 when the avoidance groove 311 is not provided. The avoidance groove 311 and the raised portion 5121 are provided, and the avoidance groove 311 and the raised portion 5121 are provided in correspondence, so that the lower beam 3 and the second wind guide wall 512 will not interfere with the blade 61, so that the size of the blade 61 can be maximized.

[0208] The second air guide wall 512 is provided with a notch 5125 extending away from the air outlet direction to form a connecting plate 5126. The connecting plate 5126 is arranged on the outer side of the lower beam 3 and opposite to the lower beam 3 for connecting with the lower beam 3, such as by screw connection or clamping.

[0209] The housing 2 includes a front plate 13, which is covered on the outer side of the second air guide wall 512 and arranged opposite to the second air guide wall 512. The front plate 13 protrudes outwards corresponding to the protrusion 5121 to avoid interference between the front plate 13 and the protrusion 5121.

[0210] The housing 2 further includes side panels 14 . There are two front panels 13 . The two front panels 13 are arranged opposite to each other. There are also two side panels 14 . Both side panels 14 are connected between the two front panels 13 .

[0211] Among the two front plates 13 , one of the front plates 13 is disposed on the first cross beam 111 , and the other front plate 13 is disposed on the second cross beam 112 .

[0212] The front plate 13 is bent toward the protective net 12 to form a folded edge 131. Support ribs 1119 are punched out on the first beam 111 and the second beam 112. The support ribs 1119 support the folded edge 131 to achieve positioning between the first beam 111 and the front plate 13, and positioning between the second beam 112 and the front plate 13.

[0213] Embodiment 2:

[0214] The difference from the first embodiment is that Figures 9 to 15 As shown, the longitudinal beam 113 is tubular, and the tube extends in a direction from the first transverse beam 111 to the second transverse beam 112 .

[0215] The main function of the longitudinal beam 113 is to enhance the strength of the frame 11, so the strength index of the longitudinal beam 113 is very important. When the width of the longitudinal beam 113 is the same, the tubular longitudinal beam 113 has a higher strength than the plate-shaped longitudinal beam 113. Therefore, when the strength of the longitudinal beam 113 is constant, the width of the tubular longitudinal beam 113 can be reduced, thereby reducing the shielding of the longitudinal beam 113 on the air outlet and reducing the wind resistance of the fan 6.

[0216] Optionally, the longitudinal beam 113 is in a flat tube shape.

[0217] Compared with round tubes, flat tubes have stronger deformation resistance, that is, higher strength.

[0218] Optionally, the longitudinal beam 113 includes a first flat tube segment 1137 , and the first flat tube segment 1137 is arranged corresponding to the fan 6 of the outdoor unit 100 , that is, the first flat tube segment 1137 is located in the middle of the longitudinal beam 113 in the length direction.

[0219] In the cross section of the first flat tube segment 1137 , the dimension along the air outlet direction of the fan 6 is larger than the dimension perpendicular to the air outlet direction, so as to reduce the shielding area of ​​the first flat tube segment 1137 on the air outlet 21 and reduce the air outlet wind resistance of the fan 6 .

[0220] Optionally, the longitudinal beam 113 further includes a second flat tube segment 1138, and the second flat tube segment 1138 is connected to the first flat tube segment 1137. The second flat tube segment 1138 and the first flat tube segment 1137 are arranged in sequence along the length direction of the longitudinal beam 113; wherein, in the cross section of the second flat tube segment 1138, the dimension along the air outlet direction of the fan 6 is smaller than the dimension along the cross section perpendicular to the air outlet direction.

[0221] The second flat tube section 1138 is staggered with the fan 6 , so the second flat tube section 1138 has less influence on the air outlet, and it is more necessary to consider the enhancement of the strength of the longitudinal beam 113 by the second flat tube section 1138 .

[0222] Taking the outdoor unit 100 as a top outlet type as an example, the longitudinal beam 113 is located above the fan 6, and the air outlet direction of the fan 6 is upward. The size of the first flat tube section 1137 in the horizontal direction (perpendicular to the air outlet direction) is smaller than the size in the vertical direction (along the air outlet direction). The size of the second flat tube section 1138 in the horizontal direction (perpendicular to the air outlet direction) is larger than the size in the vertical direction (along the air outlet direction). In this way, the longitudinal beam 113 can have greater strength.

[0223] Optionally, the first flat tube section 1137 is a hollow structure, or a solid structure, or partly a hollow structure and partly a solid structure. Fig.12 The part shown in the figure is a solid structure. Figures 13 to 15 The structure shown is a hollow structure.

[0224] The solid structure can enhance the strength of the first flat tube segment 1137 , while the hollow structure can reduce the cost of the first flat tube segment 1137 .

[0225] When part of the first flat tube segment 1137 is a hollow structure and part of it is a solid structure, the hollow structure and the solid structure are alternately arranged along the length direction of the first flat tube segment 1137 .

[0226] Optionally, the second flat tube section 1138 is a hollow structure, or a solid structure, or partly a hollow structure and partly a solid structure.

[0227] The use of a solid structure can enhance the strength of the second flat tube segment 1138 , and the use of a hollow structure can reduce the cost of the second flat tube segment 1138 .

[0228] When part of the second flat tube segment 1138 is a hollow structure and part of it is a solid structure, the hollow structure and the solid structure are alternately arranged along the length direction of the second flat tube segment 1138 .

[0229] Optionally, a smooth transition is used at the connection between the first flat tube segment 1137 and the second flat tube segment 1138 , which can enhance the strength of the longitudinal beam 113 on the one hand, and reduce the wind resistance caused by the longitudinal beam 113 on the other hand.

[0230] Optionally, the longitudinal beam 113 further includes a transition pipe section 1139 , which is connected between the first flat pipe section 1137 and the second flat pipe section 1138 , and the cross section of the transition pipe section 1139 is circular.

[0231] The connection between the first flat tube section 1137 and the second flat tube section 1138 includes a transition tube section 1139. The transition tube section 1139 is a circular tube, so that a smooth transition is achieved from the second flat tube section 1138 to the first flat tube section 1137 instead of a sudden change, thereby avoiding an increase in the wind resistance of the fan 6 caused by the sudden change.

[0232] The dimension of the first flat tube segment 1137 along the direction perpendicular to the wind outlet is smaller than the dimension of the second flat tube segment 1138 along the direction perpendicular to the wind outlet. In this way, the wind resistance can be reduced by relying on the first flat tube segment 1137 with a smaller dimension along the direction perpendicular to the wind outlet, and the strength of the longitudinal beam 113 can be increased by relying on the second flat tube segment 1138 with a larger dimension along the direction perpendicular to the wind outlet.

[0233] The longitudinal beam 113 also includes a connecting pipe section 1140, which is arranged at the end of the second flat pipe section 1138 away from the first flat pipe section 1137, and is suitable for connecting with the first cross beam 111 or the second cross beam 112. The ratio of the size of the connecting pipe section 1140 along the air outlet direction (along the upper box direction) to the size perpendicular to the air outlet direction (along the horizontal direction) is smaller than the ratio of the size of the second flat pipe section 1138 along the air outlet direction to the size perpendicular to the air outlet direction, that is, the degree of flatness of the connecting pipe section 1140 is greater than the degree of flatness of the second flat pipe section 1138, so as to facilitate the connection of the connecting pipe section 1140 with the first cross beam 111 or the second cross beam 112.

[0234] The second flat tube section 1138 may be in the shape of a plate, wherein the thickness direction of the plate extends in the wind direction, the width direction of the plate is perpendicular to the wind direction, and the width direction of the plate is greater than the thickness direction of the plate.

[0235] The longitudinal beam 113 is connected to the first cross beam 111 by clamping and / or screws, and the longitudinal beam 113 is connected to the second cross beam 112 by clamping and / or screws.

[0236] When the connection is made by screws, the screws pass through the connecting pipe section 1140 along the air outlet direction.

[0237] The connecting pipe section 1140 is a solid structure to enhance the connection strength between the connecting pipe section 1140 and the first cross beam 111 and / or the second cross beam 112 .
