The side plate is adjacent to and connected to the back plate. In the prior art, in order to improve the stability of the air conditioner assembly, screws are used to fix the back side of the side plate and the back plate. During the installation of the air conditioner, the back plate of the air conditioner is arranged close to the wall. Therefore, when the side plate needs to be removed for repairing the air conditioner, the screws will be interfered by the wall, making it inconvenient to remove.

[0064] In view of this, the embodiment of the utility model proposes an air handling unit that can ensure the convenience of disassembly of the side panel 300. It should be noted that the air handling unit can be an outdoor unit of an air conditioner, or an indoor unit of an air conditioner, or can refer to both an indoor unit and an outdoor unit of an air conditioner, depending on the actual situation. The embodiment of the application takes the air handling unit as an outdoor unit of an air conditioner as an example for explanation. Figures 1 to 17 The air handling unit of the embodiment of the present application is introduced. Specifically, the air handling unit includes a chassis 100, a heat exchanger 200 and a side panel 300.

The top wall 110 can be an upper wall surface in the middle of the chassis 100, or an upper wall surface in the periphery of the chassis 100, or can also refer to the upper wall surfaces in the middle and periphery of the chassis 100 at the same time. It can be understood that the heat exchanger 200, the side plate 300 and other components can be arranged on the top wall 110 of the chassis 100.

[0066] The heat exchanger 200 can perform heat exchange with the outside air. The specific arrangement position of the heat exchanger 200 is introduced below. The heat exchanger 200 can be connected to the top wall 110 of the chassis 100 and be located on the outside of the chassis 100. Specifically, the heat exchanger 200 can be located on the outside within the range of the chassis 100. For ease of understanding, the projection relationship between the chassis 100 and the heat exchanger 200 is used for explanation. The plane where the top wall 110 is located is defined as the projection plane. Along the direction perpendicular to the projection plane, the chassis 100 forms a first orthographic projection on the projection plane, and the heat exchanger 200 forms a second orthographic projection on the projection plane. The second orthographic projection is located within the first orthographic projection, and the second orthographic projection is located on the outside of the first orthographic projection near the edge.

[0067] The side plate 300 may be a plate body on one side of the circumference of the air conditioner housing. For ease of understanding and description, the air conditioner in working state is used as a reference. It can be understood that the air conditioner can be arranged near the wall at this time. Figure 1 and Figure 2 , the side plate 300 may be a plate body on the right side of the air conditioner housing. Fig.11 and Fig.12The side panel 300 may also be a panel on the left side of the air conditioner casing, depending on the actual situation.

[0068] Reference Figures 2 to 6 , the specific arrangement of the side panel 300 is introduced below. The side panel 300 includes a panel body 310, and the panel body 310 is the main part of the side panel 300. The side panel 300 also includes a first clamping portion 320 and a second clamping portion 330. The first clamping portion 320 and the second clamping portion 330 are located on opposite sides of the panel body 310. Specifically, in some embodiments, the first clamping portion 320 and the second clamping portion 330 may be located on both sides of the panel body 310 along its height direction. In other embodiments, the first clamping portion 320 and the second clamping portion 330 may be located on both sides of the panel body 310 along its width direction. In other embodiments, the first clamping portion 320 and the second clamping portion 330 may be located on both sides of the panel body 310 along its thickness direction. Figure 2 As a reference, the first clamping portion 320 and the second clamping portion 330 can be located on opposite sides along the inclined direction. It can be understood that the structure of the second clamping portion 330 can be the same as that of the first clamping portion 320, or a different structure can be adopted. Some embodiments of the present application are described by taking the first clamping portion 320 and the second clamping portion 330 having different structures as an example.

[0069] Reference Figure 3 , the specific assembly arrangement of the side plate 300 is described below. The first clamping portion 320 of the side plate 300 can clamp the heat exchanger 200. Specifically, the first clamping portion 320 can clamp the side of the heat exchanger 200 away from the chassis 100, so as to achieve a fixed connection between the side plate 300 and the heat exchanger 200. The second clamping portion 330 can clamp the chassis 100, so as to achieve a fixed connection between the side plate 300 and the chassis 100.

[0070] In the technical solution of the utility model, the air handling unit includes a chassis 100, a heat exchanger 200 and a side plate 300. The heat exchanger 200 is connected to the outer side of the chassis 100. The side plate 300 includes a plate body 310, a first clamping portion 320 and a second clamping portion 330. The first clamping portion 320 of the present solution is clamped to the side of the heat exchanger 200 away from the chassis 100, that is, the first clamping portion 320 is clamped to the upper side of the heat exchanger 200, which can ensure the stability of the whole machine assembly. Compared with the solution of the prior art that the side plate is connected to the back plate by screws, when disassembling the side plate 300, the present solution only needs to separate the first clamping portion 320 from the heat exchanger 200, that is, it can be free from the interference of the wall, so that the assembly and disassembly operation of the side plate 300 is convenient and quick, and the difficulty of after-sales maintenance can be effectively reduced. In addition, because the second clamping portion 330 is clamped to the chassis 100, the stability of the overall assembly connection of the side plate 300 can be improved.

[0071] Reference Figure 1 and Fig.11 In some embodiments, the housing of the air handling unit further includes a top plate 400, which is arranged opposite to the chassis 100. It is understood that one side of the side panel 300 can be connected to the chassis 100, and the other side can be connected to the top plate 400. In other embodiments, the housing may further include a mesh cover 500, which may be used for air inlet and outlet, etc. A foot 600 may be provided on the bottom side of the chassis 100, and the foot 600 may be used to support and fix the chassis 100. In other embodiments, the side panel 300 may further be provided with a handle 700, which may be made of plastic material, and the handle 700 is used to facilitate holding the side panel 300, and the stability of holding can be ensured.

[0072] The following describes the specific connection arrangement of the side panel 300. The panel body 310 of the side panel 300 includes a first panel portion 350 and a second panel portion 360 that are connected to each other. The first panel portion 350 and the second panel portion 360 are bent to each other, and the specific bending angle between the two can be determined according to actual conditions. Figure 5 Taking the orientation of as a reference, the first plate portion 350 may be a portion of the plate body 310 located on the back side, and the second plate portion 360 may be a portion of the plate body 310 located on the front side.

[0073] The chassis 100 includes a first side 120 and a second side 130 that are adjacently arranged. The first side 120 is a portion of the chassis 100 close to one side edge thereof, and the second side 130 is a portion of the chassis 100 close to the other side edge thereof. Figure 7 As a reference, the first side 120 may be the back side of the chassis 100, and the second side 130 may be the front side of the chassis 100. The heat exchanger 200 is at least partially connected to the first side 120, and the specific configuration of the heat exchanger 200 may refer to the related known technology.

[0074] In the present embodiment, the first plate portion 350 of the plate body 310 can be connected to the first side 120 of the chassis 100, and the second plate portion 360 can be connected to the second side 130 of the chassis 100, which can ensure the stability of the bottom connection of the plate body 310, and the first clamping portion 320 is arranged on the side of the first plate portion 350 away from the chassis 100, which can make the upper side of the plate body 310 reliably connected to the heat exchanger 200, thereby effectively improving the stability of the overall assembly connection of the side plate 300.

[0075] Reference Figure 4 , the specific location of the second clamping portion 330 is described below. In some embodiments, the second clamping portion 330 can be arranged on the side of the second plate portion 360 connected to the chassis 100, that is, the bottom side of the second plate portion 360 can be fixed by the second clamping portion 330, thereby ensuring the stability of the assembly connection of the side plate 300.

[0076] Reference Figure 6 , Fig.16 and Fig.17 , the air handling unit also includes a third clamping portion 340. The structure of the third clamping portion 340 may be the same as or different from that of the second clamping portion 330. In some embodiments of the present application, the third clamping portion 340 and the second clamping portion 330 have different structures as an example for explanation. In addition, the third clamping portion 340 may be arranged on the side of the first plate portion 350 connected to the chassis 100, that is, the first plate portion 350 can be clamped with the chassis 100 through the third clamping portion 340, and because the second plate portion 360 can be clamped with the chassis 100 through the second clamping portion 330, and the first plate portion 350 can be clamped with the heat exchanger 200 through the first clamping portion 320. Therefore, the side panel 300 of this solution can be clamped at three positions, effectively improving the stability of the pre-fixation of the side panel 300.

[0077] Reference Figure 2 , the relative arrangement positions of the second clamping portion 330 and the third clamping portion 340 are introduced below. In some embodiments, the second clamping portion 330 can be arranged at one end of the second plate portion 360 away from the first plate portion 350, and the third clamping portion 340 can be arranged at one end of the first plate portion 350 away from the second plate portion 360. This solution can ensure that the second clamping portion 330 and the third clamping portion 340 are spaced at a large distance, effectively improving the stability of the assembly connection between the side plate 300 and the chassis 100. It should be noted that the third clamping portion 340 can be located directly below the first clamping portion 320, or can be located at the oblique lower side of the first clamping portion 320, and its specific arrangement position can be determined according to actual conditions.

[0078] In order to facilitate the description and understanding of the specific assembly and disassembly process between the side plate 300 and the chassis 100, the direction from the bottom wall 150 of the chassis 100 to the top wall 110 is defined as the first direction Z. Figure 2 The first direction Z can point to the up and down direction with reference to the orientation in FIG. 1 . In some embodiments, the first clamping portion 320 and the second clamping portion 330 are both configured to be able to detach from the chassis 100 along the first direction Z. Compared with the solution in which the first clamping portion and the second clamping portion are detached from the chassis in different directions respectively, the separation process of the side plate 300 and the chassis 100 in this solution is convenient and quick, that is, the disassembly efficiency of the side plate 300 can be effectively improved. It can be understood that when the side plate 300 is assembled with the chassis 100, the side plate 300 can be moved in the opposite direction of the first direction Z so that the first clamping portion 320 clamps the heat exchanger 200 and the second clamping portion 330 clamps the chassis 100. It should be noted that when the side plate 300 is additionally provided with a third clamping portion 340, the side plate 300 can also be moved along the first direction Z to separate the third clamping portion 340 from the chassis 100.

[0079] Reference Figure 3, the specific connection setting of the first clamping part 320 and the heat exchanger 200 is introduced below. In some embodiments, the first clamping part 320 can be provided with a first clamping groove 321, and the heat exchanger 200 can be provided with a protrusion 210. In the opposite direction of the first direction Z, the protrusion 210 of the heat exchanger 200 can be inserted into the first clamping groove 321 of the first clamping part 320. In other embodiments, the first clamping part 320 is provided with a protrusion 210, and the heat exchanger 200 can be provided with a first clamping groove 321. In the first direction Z, the protrusion 210 of the first clamping part 320 can be inserted into the first clamping groove 321 of the heat exchanger 200. The specific setting positions of the first clamping groove 321 and the protrusion 210 can be determined according to actual conditions. It can be understood that the notch of the first clamping groove 321 can be arranged toward the chassis 100. The protruding portion 210 in this solution is provided with a first clamping groove 321 , which can ensure the stability of the connection between the first clamping portion 320 and the heat exchanger 200 .

[0080] Reference Figure 8 , the specific structure of the first clamping portion 320 is introduced below. In some embodiments, the first clamping portion 320 includes a first rib 322 and a second rib 323. Among them, the first rib 322 and the second rib 323 are bent to each other, and the specific bending angles of the first rib 322 and the second rib 323 can be determined according to actual conditions. The second rib 323 can be connected to the end of the first rib 322 that is away from the first plate portion 350. The second rib 323 can define a first slot 321 together with the first rib 322. When the protrusion 210 is penetrated by the first slot 321, it can limit the side plate 300 from being separated from the heat exchanger 200 in a direction perpendicular to the first direction Z, thereby ensuring the stability of the connection between the side plate 300 and the heat exchanger 200.

[0081] It can be understood that the first retaining edge 322 and the second retaining edge 323 can both be plate-shaped, that is, the first retaining edge 322 and the second retaining edge 323 can both be integrally formed with the plate body 310, which can facilitate processing and omit the assembly process between the first clamping portion 320 and the plate body 310. In other embodiments, the first clamping portion 320 can also directly open a groove body to form a clamping groove, and the specific structure and setting of the clamping groove can be determined according to actual conditions.

[0082] In order to improve the stability of the connection between the first clamping portion 320 and the protruding portion 210 of the heat exchanger 200, the first clamping groove 321 needs to be set to a smaller size, that is, the second retaining edge 323 needs to be bent significantly relative to the first retaining edge 322, which will reduce the strength of the bend between the first retaining edge 322 and the second retaining edge 323, thereby affecting the overall structural strength of the first clamping portion 320, that is, the stability of the connection between the first clamping portion 320 and the heat exchanger 200 cannot be guaranteed. Therefore, in some embodiments, referring to Figure 8, the second rib 323 is provided with a first folded edge 3231. In order to facilitate the description and understanding of the specific setting of the first folded edge 3231, a second direction X is defined. The direction from the second rib 323 to the first rib 322 is set as the second direction X, and the second direction X intersects with the first direction Z. Specifically, the second direction X can be perpendicular to the first direction Z, or can be at other non-perpendicular angles. Along the second direction X, the first folded edge 3231 extends toward the first rib 322. It can be understood that the end of the first folded edge 3231 close to the first rib 322 can be spaced from the first rib 322. The first folded edge 3231 can define the first card slot 321 together with the first retaining edge 322. By setting the first folded edge 3231, the present solution can effectively reduce the clamping size of the first card slot 321, ensure the stability of the assembly connection between the protrusion 210 of the heat exchanger 200 and the first card slot 321, and avoid the second retaining edge 323 from bending significantly relative to the first retaining edge 322, thereby improving the overall structural strength.

[0083] Reference Figure 7 and Figure 8 In some embodiments, the first plate portion 350 is provided with a second folded edge 351, and the second folded edge 351 can be provided at one end of the first plate portion 350 away from the second plate portion 360. To facilitate description and understanding of the specific setting of the second folded edge 351, the direction from the second rib 323 to the first rib 322 is set as the second direction X, and the second direction X intersects the first direction Z. Specifically, the second direction X can be perpendicular to the first direction Z, or can be at other non-perpendicular angles. Along the second direction X, the second folded edge 351 extends toward the second rib 323.

[0084] It should be noted that in some embodiments, the extension length of the second folded edge 351 along the second direction X may be less than the distance from the second rib 323 to the first rib 322. In other embodiments, the extension length of the second folded edge 351 along the second direction X may be greater than the distance from the second rib 323 to the first rib 322. The specific extension length of the second folded edge 351 may be determined according to actual conditions. This solution can effectively improve the verticality of the side of the first plate portion 350 by setting the second folded edge 351, effectively suppress the bending of the first plate portion 350, and ensure the stability of the assembly connection of the side plate 300.

[0085] Reference Figure 4 and Fig. 9, the specific clamping arrangement of the second clamping portion 330 and the chassis 100 is introduced below. In some embodiments, the second clamping portion 330 can be provided with a second clamping groove 331, and the chassis 100 can be provided with a flange 140. Along the first direction Z, the flange 140 of the chassis 100 can penetrate the second clamping groove 331 of the second clamping portion 330. In other embodiments, the second clamping portion 330 can also be provided with a flange 140, and the chassis 100 can be provided with a second clamping groove 331. In the opposite direction of the first direction Z, the flange 140 of the second clamping portion 330 can penetrate the second clamping groove 331 of the chassis 100. The notch of the second clamping groove 331 can be arranged toward the chassis 100. The flange 140 in this solution can penetrate the second clamping groove 331, that is, it can ensure the stability of the assembly connection between the second clamping portion 330 and the chassis 100.

[0086] Reference Fig. 9 , the specific structure of the second clamping portion 330 is introduced below. In some embodiments, the second clamping portion 330 includes a third rib 332 and a fourth rib 333. Among them, the third rib 332 and the fourth rib 333 are bent and arranged with each other, and the specific bending angles of the third rib 332 and the fourth rib 333 can be determined according to actual conditions. The fourth rib 333 can be connected to the end of the third rib 332 that is away from the second plate portion 360. The fourth rib 333 can define a second slot 331 together with the third rib 332. When the flange 140 is penetrated by the second slot 331, it can limit the side plate 300 from being separated from the chassis 100 in a direction perpendicular to the first direction Z, thereby ensuring the stability of the connection between the side plate 300 and the heat exchanger 200.

[0087] It can be understood that the third rib 332 and the fourth rib 333 can both be plate-shaped, that is, the third rib 332 and the fourth rib 333 can both be integrally formed with the plate body 310, which can facilitate processing and omit the assembly process between the second clamping portion 330 and the plate body 310. In other embodiments, the second clamping portion 330 can also directly open a groove body to form a clamping groove, and the specific setting of the second clamping groove 331 can be determined according to actual conditions.

[0088] In order to improve the stability of the connection between the second clamping portion 330 and the chassis 100, the second clamping groove 331 needs to be set to a smaller size, that is, the fourth retaining edge 333 needs to be bent significantly relative to the third retaining edge 332, which will reduce the strength of the bend between the fourth retaining edge 333 and the third retaining edge 332, thereby affecting the overall structural strength of the second clamping portion 330, that is, the stability of the connection between the second clamping portion 330 and the chassis 100 cannot be guaranteed. Therefore, in some embodiments, referring to Figures 13 to 15, the fourth rib 333 is provided with a third folded edge 3331. In order to facilitate the description and understanding of the specific setting of the third folded edge 3331, a third direction Z is defined. The direction from the fourth rib 333 to the third rib 332 is set as the third direction Z, and the third direction Z intersects with the first direction Z. Specifically, the third direction Z can be perpendicular to the first direction Z, or can be at other non-perpendicular angles. Along the third direction Z, the third folded edge 3331 extends toward the third rib 332. The third folded edge 3331 can define the second slot 331 together with the third rib 332.

[0089] It can be understood that the end of the third folded edge 3331 close to the third rib 332 can be spaced apart from the third rib 332. The third folded edge 3331 can define the second slot 331 together with the third rib 332. The present solution can effectively reduce the size of the second slot 331 by providing the third folded edge 3331, ensure the stability of the assembly connection between the flange 140 and the second slot 331, and avoid the fourth rib 333 being bent significantly relative to the third rib 332, thereby improving the overall structural strength.

[0090] Reference Fig.12 In some embodiments, the side plate 300 may further be provided with a fourth clamping portion 370, and the fourth clamping portion 370 may be located on a side of the second clamping portion 330 away from the third clamping portion 340. Specifically, the fourth clamping portion 370 may be provided with a fourth clamping slot, and the chassis 100 may be provided with a flange 140. The flange 140 of the chassis 100 may be provided with a fourth clamping slot of the fourth clamping portion 370 to achieve a stable connection between the chassis 100 and the side plate 300.

[0091] Reference Fig.16 In some embodiments, a second guide portion 361 is provided at one end of the second plate portion 360 away from the first plate portion 350, and the second guide portion 361 is bent relative to the second plate portion 360. It can be understood that the bending angle of the second guide portion 361 relative to the second plate portion 360 can be an obtuse angle, a right angle, an acute angle, etc. Some embodiments of the present application are described by taking the bending of the second guide portion 361 relative to the second plate portion 360 at an obtuse angle as an example. It should be noted that the second guide portion 361 can extend only a partial length on the second plate portion 360, or it can extend to the entire second plate portion 360. The second guide portion 361 of this solution can improve the assembly connection accuracy of the second plate portion 360 and its adjacent side panel (which can be a front panel or a rear panel), and can suppress the bending deformation of the second plate portion 360 to ensure its structural strength.

[0092] In other embodiments, a first guide portion is provided at one end of the first plate portion 350 facing away from the second plate portion 360, and the first guide portion can be bent relative to the first plate portion 350. It can be understood that the bending angle of the first guide portion relative to the first plate portion 350 can be an obtuse angle, a right angle, an acute angle, etc. Some embodiments of the present application are described by taking the bending of the first guide portion at an obtuse angle relative to the first plate portion 350 as an example. It should be noted that the first guide portion can extend only a partial length on the first plate portion 350, or it can extend to the entire first plate portion 350. The first guide portion of this solution can improve the assembly connection accuracy of the first plate portion 350 and its adjacent side panel (which can be a front panel or a rear panel), and can suppress the bending deformation of the first plate portion 350 to ensure its structural strength.

[0093] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.
