[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on August 23, 2023, with application number 202311073427X and invention name “Air Conditioning Chassis Structure, Air Conditioning Outdoor Unit and Air Conditioner”, the entire text of which is incorporated herein by reference. Technical Field

[0003] The present application relates to the technical field of air conditioning, and in particular to an air conditioning chassis structure, an air conditioning outdoor unit and an air conditioner. Background Art

[0004] In the prior art, the heat exchanger of an air conditioner's outdoor unit is typically placed directly on the chassis, which is also equipped with drainage holes. However, when the air conditioner's outdoor unit's fan is operating, the drainage holes at the bottom of the heat exchanger can easily create a significant negative pressure, causing condensation inside the unit to spread along the air flow, hindering the drainage of the condensation. Condensation that cannot be discharged in a timely manner will gradually freeze inside the chassis and on the mesh cover, causing negative effects such as heat exchange damage, fan blade damage, and reduced airflow, affecting the operation of the air conditioner's outdoor unit.

[0057] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0061] In the prior art, the heat exchanger of an air conditioner's outdoor unit is typically placed directly on the chassis, which is also equipped with drainage holes. However, when the air conditioner's outdoor unit's fan is operating, the drainage holes at the bottom of the heat exchanger can easily create a significant negative pressure, causing condensation inside the unit to spread along the air flow, hindering the drainage of the condensation. Condensation that cannot be discharged in a timely manner will gradually freeze inside the chassis and on the mesh cover, causing negative effects such as heat exchange damage, fan blade damage, and reduced airflow, affecting the operation of the air conditioner's outdoor unit.

[0062] Referring to FIG1 , one aspect of the present application provides an air conditioner comprising an indoor unit (not shown) and an outdoor unit 1000 . The indoor unit is installed indoors, and the outdoor unit 1000 is connected to the indoor unit via a pipeline. The outdoor unit 1000 is responsible for cooling or heating, and transports refrigerant through the pipeline. The refrigerant exchanges heat with the indoor air and the outdoor air, respectively. The indoor unit is responsible for delivering the cold or hot air into the room to achieve a cooling or heating effect.

[0063] On the other hand, the present application provides an air conditioning outdoor unit 1000. Referring to Figures 1 to 4, in an embodiment of the present application, the air conditioning outdoor unit 1000 includes an air conditioning chassis structure 100, and a heat exchanger 200, a fan 300, and a compressor (not shown in the figures) supported on the air conditioning chassis structure 100. The air conditioning chassis structure 100 forms the main frame of the air conditioning outdoor unit 1000. The air conditioning chassis structure 100 can be made of metal to improve the structural strength of the air conditioning chassis structure 100, thereby ensuring the stability of supporting and mounting the heat exchanger 200, the fan 300, and the compressor.

[0064] Referring to Figure 5 , a refrigerant pipe 204 is provided inside the heat exchanger. During the cooling process, the refrigerant flows from the compressor to the heat exchanger 200 of the outdoor air conditioner 1000, and then to the heat exchanger of the indoor air conditioner. At this point, the heat exchanger 200 of the outdoor air conditioner 1000 acts as a condenser, condensing the high-temperature, high-pressure refrigerant from the compressor. The heat exchanger of the indoor air conditioner acts as an evaporator, exchanging heat between the low-temperature refrigerant and the indoor air, thereby delivering cool air. The refrigerant then circulates back to the compressor. During the heating process, the refrigerant flows from the compressor to the heat exchanger of the indoor air conditioner, and then to the heat exchanger 200 of the outdoor air conditioner 1000. The high-temperature refrigerant from the compressor exchanges heat with the indoor air, delivering warm air. In this case, the heat exchanger of the indoor air conditioner acts as a condenser, and the heat exchanger 200 of the outdoor air conditioner 1000 acts as an evaporator. The refrigerant then circulates back to the compressor. The air inlet side 200A of the heat exchanger 200 of the air conditioner outdoor unit 1000 is located outside the air conditioner outdoor unit 1000, and the air outlet side 200B of the heat exchanger 200 is located inside the air conditioner outdoor unit 1000. Furthermore, the air conditioner outdoor unit 1000 further includes a top cover 400 and a vertically extending enclosure 500. Thus, the air conditioner chassis structure 100, the enclosure 500, and the top cover 400 cooperate to form a housing space, and the heat exchanger 200, the fan 300, and the compressor are all located within the housing space. The enclosure 500 is provided with an air outlet 501, and the fan 300 can be an axial flow fan 300, which is fixed to the air conditioner chassis structure 100 through a bracket. The axial flow fan 300 is located on the air outlet side 200B of the heat exchanger 200, so that the fan 300 rotates so that the external air flow can be blown out from the air outlet 501 to the outdoor environment after heat exchange from the air inlet side 200A of the heat exchanger 200 through the air outlet side 200B.

[0065] In order to ensure smooth drainage of condensed water generated in the heat exchanger 200 of the air conditioner outdoor unit 1000 during use, the present application provides an air conditioner chassis structure 100, with reference to Figures 3, 4, 6, and 7. The air conditioner chassis structure 100 is supported below the heat exchanger 200. The air conditioner chassis structure 100 includes a chassis body 10, which has a drainage hole 10A formed below the heat exchanger 200. The drainage hole 10A extends through two opposing surfaces of the chassis body 10 in the thickness direction. The drainage hole 10A is at least partially exposed on the air inlet side 200A of the heat exchanger 200 and communicates with the external space of the air inlet side 200A of the heat exchanger 200.

[0066] It should be noted that after the heat exchanger 200 is placed on the tray body 10, it is secured to the tray body 10 using clips or screws to ensure the stability of the tray body 10 supporting the bottom of the heat exchanger 200. Drain holes 10A penetrate the two opposing surfaces of the tray body 10 in the thickness direction. This allows condensed water generated during operation of the heat exchanger 200 to flow to the bottom of the heat exchanger 200 under the action of gravity and then be discharged to the outside through the drain holes 10A in the tray body 10. The opening shape of the drain holes 10A can be arranged in a strip shape along the extension direction of the heat exchanger 200. Of course, the drain holes 10A can also have a regular shape such as a circle or rectangle to facilitate regular arrangement on the tray body 10.

[0067] 3 and 5 , the air conditioner chassis structure 100 optionally further includes a plurality of support legs 50, which are connected to the surface of the chassis body 10 facing away from the heat exchanger 200, and the plurality of support legs 50 are staggered with the drainage holes 10A. The plurality of support legs 50 can be connected to the surface of the chassis body 10 facing away from the heat exchanger 200 by means of screws or snaps, and the support legs 50 can be placed on an external support surface, thereby creating a gap between the chassis body 10 and the external support surface, and the support legs 50 are staggered with the drainage holes 10A, thereby facilitating smooth drainage of the drainage holes 10A. Furthermore, support leg drainage holes 51 are provided on the support legs 50, which penetrate the two opposing surfaces in the thickness direction, thereby facilitating the flow of accumulated water above the support legs 50 to the external support surface.

[0068] Based on the air conditioner chassis structure 100 of the embodiment of the present application, by making the drain hole 10A of the chassis body 10 at least partially exposed on the air inlet side 200A of the heat exchanger 200, the drain hole 10A is connected to the space on the air inlet side 200A of the heat exchanger 200. Since the drain hole 10A is connected to the air outside the air inlet side 200A of the condenser, air circulation at the bottom of the heat exchanger 200 is improved, and a large negative pressure is not easily formed at the drain hole 10A, which greatly reduces the difficulty of condensed water draining from the drain hole 10A, ensuring the drainage efficiency of the drain hole 10A. At the same time, it prevents external accumulated water from being sucked back into the air conditioner chassis structure 100 through the drain hole 10A. It also makes it easy for outsiders to observe the blockage of the drain hole 10A, ensuring the stable drainage function of the drain hole 10A, and improving the technical problem of poor drainage from the drain hole 10A.

[0069] Referring to Figures 4 and 6 , drain hole 10A optionally includes a first hole portion 10a and a second hole portion 10b that communicate with each other. The first hole portion 10a is located within the projection of the heat exchanger 200 onto the disk body 10, while the second hole portion 10b is exposed on the air inlet side 200A of the heat exchanger 200. The opening area of ​​the first hole portion 10a is larger than the opening area of ​​the second hole portion 10b. As such, the first hole portion 10a is located within the projection of the heat exchanger 200 onto the disk body 10, i.e., directly below the heat exchanger 200. Even if condensed water or other moisture within drain hole 10A is blown up by external airflow, the heat exchanger 200 is located above the first hole portion 10a of drain hole 10A, preventing the moisture from being blown into the housing through drain hole 10A and contacting components such as the fan 300. The second hole portion 10b is exposed on the air inlet side 200A of the heat exchanger 200 to communicate with the space on the air inlet side 200A of the heat exchanger 200. By making the opening area of ​​the first hole portion 10a larger than the opening area of ​​the second hole portion 10b, the facing area between the drainage hole 10A and the bottom of the heat exchanger 200 is increased, thereby further improving the drainage efficiency of the drainage hole 10A for the condensed water of the heat exchanger 200.

[0070] 4 and 7 , optionally, a groove 111 is formed on the surface of the disk body 10 facing the heat exchanger 200. The heat exchanger 200 is disposed in the groove of the groove 111, and the drainage hole 10A is provided at the bottom of the groove 111. It should be noted that the dotted outline in FIG7 is the outline of the heat exchanger 200. The groove 111 is located at the edge of the disk body 10, so that the heat exchanger 200 is also located at the edge of the disk body 10, so that external airflow passes through the air inlet side 200A of the heat exchanger 200. By forming the groove 111 on the disk body 10 for mounting the heat exchanger 200, not only can the installation efficiency of the heat exchanger 200 be improved, but the condensed water from the heat exchanger 200 can also be effectively reduced from flowing to other locations of the disk body 10.

[0071] 4 , 7 , and 8 , the groove 111 optionally includes a connected support groove 1111 and a drain groove 1112. The bottoms of the support groove 1111 and the drain groove 1112 are arranged in a stepped manner, with the bottom of the support groove 1111 located above the bottom of the drain groove 1112. The bottom of the heat exchanger 200 is supported by the bottom surface of the support groove 1111, and the bottom of the drain groove 1112 is provided with a drain hole 10A.

[0072] It should be noted that the bottom surface of the support groove 1111 in this embodiment is filled with the first pattern P1 as shown in Figures 4, 6, 7, 13, and 14. The first pattern P1 is in the form of a rectangular array of blocks. The bottom surface of the support groove 1111 is flat, ensuring the stability of the heat exchanger 200 when placed in the support groove 1111. By positioning the bottom of the support groove 1111 above the bottom of the drainage groove 1112, the plane of the tray body 10 where the drainage holes 10A are located is positioned below the bottom support surface of the tray body 10 on the heat exchanger 200. Consequently, if excessive condensation water accumulates or the drainage holes 10A become clogged, the accumulated water will remain in the drainage groove 1112, preventing prolonged contact with the bottom of the heat exchanger 200.

[0073] Furthermore, the drainage groove 1112 is exposed on the air inlet side 200A of the heat exchanger 200 and communicates with the space on the air inlet side 200A of the heat exchanger 200. By making the drainage groove 1112 communicate with the space on the air inlet side 200A of the heat exchanger 200, it is difficult for the drainage groove 1112 to generate negative pressure, thereby ensuring smooth water flow in the drainage groove 1112 and reducing the risk of clogging by debris such as leaves and dirt during subsequent use.

[0074] 4 and 7 , a plurality of drainage holes 10A are optionally defined at the bottom of the drainage groove 1112, and the plurality of drainage holes 10A are spaced apart along the extending direction of the drainage groove 1112. The plurality of drainage holes 10A are connected through the drainage groove 1112, so that even if one of the drainage holes 10A is blocked, condensed water can flow to the other drainage holes 10A through the drainage groove 1112, thereby preventing local drainage failure and ensuring drainage efficiency.

[0075] Referring to Figure 8 , the distance between the bottom of the drain groove 1112 and the bottom of the support groove 1111 is optionally greater than 2 mm. To accommodate the later installation environment of the air conditioner outdoor unit 1000, it is necessary to control the discharge location of the condensed water from the outdoor air conditioner, thereby installing silicone plugs to seal some of the drain holes 10A. To prevent the silicone plugs from damaging the condenser, the distance between the bottom of the drain groove 1112 and the bottom of the support groove 1111 is greater than 2 mm, thereby increasing the gap between the plane of the tray body 10 at the drain hole 10A and the bottom support surface of the tray body 10 at the heat exchanger 200. This prevents the subsequent installation of the silicone plugs from affecting the heat exchanger 200 and ensures normal operation of the heat exchanger 200.

[0076] Referring to Figures 2 to 4 and 7, heat exchanger 200 optionally includes a first heat exchange section 201 and a second heat exchange section 202 arranged at an angle, and drainage groove 1112 includes a first sub-groove 111A and a second sub-groove 111B. First sub-groove 111A is located below first heat exchange section 201 and extends along the length of first heat exchange section 201. Second sub-groove 111B is located below second heat exchange section 202 and extends along the length of second heat exchange section 202. Drain holes 10A are formed at the bottoms of first sub-groove 111A and second sub-groove 111B. The first and second heat exchange sections 201, 202 can be arranged at a right angle to each other, thereby increasing the contact area between the air inlet side 200A of the heat exchange section and the outside world. By providing the first sub-trough 111A corresponding to the first heat exchange part 201 and the second sub-trough 111B corresponding to the second heat exchange part 202, the condensed water generated by the first heat exchange part 201 and the second heat exchange part 202 can be discharged respectively, thereby improving the drainage efficiency.

[0077] With reference to Figures 4, 7, 11, and 12, in one embodiment, a drainage groove 1112 is formed on the surface of the tray body 10 facing the heat exchanger 200. The drainage groove 1112 includes a first sub-groove 111A and a second sub-groove 111B that are interconnected. The first sub-groove 111A and / or the second sub-groove 111B include a first groove section 10A and a second groove section 111b that are alternately interconnected. The bottom of the first groove section 10A is provided with a drainage hole 10A. The second groove section 111b is smaller in the direction from the air inlet side 200A to the air outlet side 200B of the heat exchanger 200 than the first groove section 10A in the direction from the air inlet side 200A to the air outlet side 200B of the heat exchanger 200.

[0078] In this way, the opening distance of the first groove section 10A with the drainage hole 10A is larger than the opening distance of the second groove section 111b without the drainage hole 10A, thereby ensuring the drainage efficiency and the contact area between the disk body and the heat exchanger 200, thereby ensuring the stability of the chassis supporting the heat exchanger 200.

[0079] Referring to Figures 1, 2, 4 and 13, optionally, the disk body 10 includes a base plate 11 and a partition plate 12 connected to the base plate 11, the base plate 11 includes a fan area NA and a mechanical area AA located on opposite sides of the partition plate 12, and a heat exchange area BA located at the edge of the fan area NA, the heat exchange area BA is recessed toward the surface of the heat exchanger 200 to form a groove 111, the drainage hole 10A is provided at the bottom of the groove 111, the fan area NA includes a junction adjacent to the groove 111, and the groove 111 is recessed relative to the junction.

[0080] The partition plate 12 can be configured as a boss to accommodate a partition 600. The partition 600 can be secured to the partition plate 12 by screws or welding, thereby partitioning the space within the air conditioner outdoor unit 1000. It is understood that the fan area NA is configured to accommodate the fan 300, the mechanical area AA can be configured to accommodate the compressor, and the heat exchange area BA has a recess 111 configured to accommodate the heat exchanger 200. The fan area NA is provided with a boss to serve as a bracket for mounting the fan 300, thereby increasing the support strength of the base plate 11 for the fan 300.

[0081] Furthermore, with reference to Figure 14 , the base plate 11 is provided with a first water outlet 112, which extends through two opposing surfaces of the base plate 11 in the thickness direction and is located on the side of the heat exchange area BA near the mechanical area AA. The base plate 11 is also provided with a first guide groove 113, which extends from the mechanical area AA to the heat exchange area BA and communicates with the first water outlet 112. It should be noted that in this embodiment, the bottom surface of the first guide groove 113 is filled with a second pattern P2, as shown in Figures 13 and 14 . The second pattern P2 is arranged in a hexagonal array. The heat exchange area BA of the base plate 11 is provided with a groove 111, and the bottom surface of the groove 111 is lower than the bottom surface of the first guide groove 113. That is, the plane of the heat exchange area BA of the base plate 11 is lower than the plane of the base plate 11 in the fan area NA. This allows condensed water and other accumulated water in the fan area NA to flow easily into the groove 111 due to gravity and then out through the drainage hole 10A. By opening a first water outlet 112 in the heat exchange area BA of the bottom plate 11, and setting a first guide groove 113 so that the mechanical area AA extends to the heat exchange area BA and is connected with the first water outlet 112, the condensed water and other accumulated water in the mechanical area AA can be discharged from the first water outlet 112 along the first guide groove 113, so as to avoid opening a through hole in the mechanical area AA for drainage, and prevent foreign objects such as external insects from easily entering the mechanical area AA and causing damage to equipment such as the compressor.

[0082] Furthermore, the bottom surface of the first guide groove 113 gradually decreases toward the extension direction of the first water outlet 112. This can further increase the flow rate of the accumulated water in the first guide groove 113 to prevent condensed water and other accumulated water from staying in the mechanical area AA of the disk body 10 for too long.

[0083] 4 and 13 , optionally, the first guide groove 113 extends in a circumferentially zigzag manner within the mechanical area AA, so as to collect condensed water and other accumulated water at various locations in the mechanical area AA.

[0084] 4 , 5 , and 14 , optionally, the bottom plate 11 is provided with a recessed portion 114 at the bottom of the support groove 1111. The recessed portion 114 is located between the first water outlet 112 and the mechanical area AA, and opposite ends of the recessed portion 114 communicate with the first guide groove 113. Forming the recessed portion 114 at the bottom of the support groove 1111 to communicate with the first guide groove 113 increases the flow rate from the first guide groove 113 to the first water outlet 112, thereby improving the drainage efficiency of accumulated water such as condensed water in the mechanical area AA.

[0085] Optionally, referring to Figures 13 and 14, a drainage groove 1112 is formed on the surface of the disk body 10 facing the heat exchanger 200. The drainage groove 1112 includes a first sub-groove 111A and a second sub-groove 111B that are connected. The second sub-groove 111B is connected to the first water outlet 112. This allows condensed water and other accumulated water in the second sub-groove 111B to be discharged from the first water outlet 112. When the first water outlet 112 is blocked, the water in the first guide groove 113 can also flow into the second sub-groove 111B and be discharged from the drainage hole 10A of the second sub-groove 111B, thereby ensuring the overall drainage efficiency and smoothness of the bottom plate 11.

[0086] Referring to Figures 4, 13, and 15, the bottom plate 11 optionally further includes a second water outlet 115 extending through two opposing surfaces in the thickness direction of the bottom plate 11. The second water outlet 115 is located below the junction of the first heat exchange section 201 and the second heat exchange section 202. The heat exchange area BA further includes a second guide groove 117 connecting the fan area NA and the second water outlet 115. The second water outlet 115 can not only be configured to discharge condensed water at the junction of the first heat exchange section 201 and the second heat exchange section 202, but also direct condensed water from the fan area NA to the second water outlet 115 for discharge through the second guide groove 117. Furthermore, the bottom surface of the second guide groove 117 gradually decreases toward the direction in which the second water outlet 115 extends. This further increases the flow rate of the condensed water directed to the second water outlet 115.

[0087] Furthermore, at least a portion of the second water outlet 115 is exposed on the air inlet side 200A of the heat exchanger 200 and communicates with the space outside the air inlet side 200A of the heat exchanger 200. This prevents a significant negative pressure from forming at the second water outlet 115, greatly reducing the difficulty of draining condensed water from the second water outlet 115 and ensuring efficient drainage. It also prevents external water from being sucked back into the air conditioner chassis structure 100 through the second water outlet 115 and makes it easier for outsiders to observe blockage in the drain hole 10A.

[0088] Referring to Figures 4, 12, and 15, the bottom of the support groove 1111 of the bottom plate 11 is further provided with a through groove 116, which connects the second water outlet 115 and the first sub-groove 111A. This allows condensed water and other accumulated water in the first sub-groove 111A to be drained through the second water outlet 115. Furthermore, when the second water outlet 115 is blocked, the water in the second guide groove 117 can flow into the first sub-groove 111A and be discharged through the drainage hole 10A in the first sub-groove 111A, thereby ensuring the overall drainage efficiency and smoothness of the bottom plate 11.

[0089] Referring to Figures 13 and 15 , the tray body 10 further includes a flange 13 connected to the outer periphery of the base plate 11. At least a portion of the flange 13 abuts the surface of the air inlet side 200A of the heat exchanger 200. The flange 13 can be integrally formed with the base plate 11 to ensure the stability of the flange 13 abutting the surface of the air inlet side 200A of the heat exchanger 200. The provision of the flange 13 improves the stability of the heat exchanger 200 when mounted on the base plate 11. Furthermore, the flange 13 can also be connected to and limited by other components supported on the base plate 11.

[0090] Furthermore, the flange 13 includes a connected abutment portion 132 and a relief portion 133. The abutment portion 132 abuts the surface of the air inlet side 200A of the heat exchanger 200, while the relief portion 133 is recessed away from the air inlet side 200A of the heat exchanger 200. The relief portion 133 is positioned opposite a drain hole 10A. The abutment portion 132 abuts against the surface of the air inlet side 200A of the heat exchanger 200 to maintain position, ensuring the stability of the heat exchanger 200 after installation. The relief portion 133 is recessed away from the air inlet side 200A of the heat exchanger 200 to avoid blocking the drain hole 10A and thus ensure the stability of the spatial connection between the drain hole 10A and the air inlet side 200A of the heat exchanger 200.

[0091] Referring to Figures 4, 13, and 16, the air conditioner chassis structure 100 optionally further includes a column 30. The column 30 is connected to the flange 13 and is located on the side of the air inlet side 200A of the heat exchanger 200 facing away from the air outlet side 200B. The column 30 extends to the junction of the first heat exchange portion 201 and the second heat exchange portion 202 and blocks the second water outlet 115. The column 30 can be secured to the flange 13 by means of a snap or screw connection. In this embodiment, a mounting hole 31 can be defined in the column 30, and a corresponding connection hole 135 can be defined in the flange 13. A screw or other connecting member can be inserted through the mounting hole 31 and the connection hole 135 in sequence for securing the heat exchanger 200. The column 30 can also be connected to the top cover 400 of the air conditioner outdoor unit 1000, thereby providing support and reducing the stress on the heat exchanger 200. At the same time, the column 30 extends to the junction of the first heat exchange part 201 and the second heat exchange part 202 and blocks the second water outlet 115, thereby preventing leaves or debris from clogging the second water outlet 115 and ensuring the normal drainage function of the second water outlet 115.

[0092] Optionally, referring to Figures 2, 4, 8, 9, and 13, the air conditioner chassis structure 100 further includes an inner stopper 20 connected to the base plate 11. The inner stopper 20 abuts the outlet surface 200B of the heat exchanger 200. The base plate 11 has a fixing groove formed in the fan area NA. The inner stopper 20 can be screwed or welded to the fixing groove of the base plate 11 and positioned opposite the flange 13. When the heat exchanger 200 is placed on the base plate 11, the stopper and flange 13 abut against the opposing surfaces of the heat exchanger 200, thereby securing the heat exchanger 200 and ensuring stability after installation. The inner stopper 20 may be a sheet metal part to enhance abutment strength. To further enhance abutment strength, multiple inner stoppers 20 may be provided, and the specific number of inner stoppers 20 can be determined by those skilled in the art.

[0093] 12 , optionally, a rib 131 is provided on the surface of the flange 13 facing the column 30. The rib 131 abuts against the surface of the column 30 facing away from the air inlet side 200A. The rib 131 abuts against the column 30, thereby further improving the stability of the column 30 after installation.

[0094] Referring to Figures 2 and 16, optionally, the heat exchanger 200 also includes two side mounting plates 203, one side mounting plate 203 is connected to the surface of the first heat exchange part 201 facing away from the second heat exchange part 202, and the other side mounting plate 203 is connected to the surface of the second heat exchange part 202 facing away from the first heat exchange part 201, and the flange 13 includes two side mounting parts 134 arranged corresponding to the two side mounting plates 203, and the side mounting parts 134 are recessed toward the surface direction of the side mounting plates 203, and one side mounting part 134 is connected to the side mounting plate 203. Among them, the ends of the first heat exchange part 201 and the second heat exchange part 202 are respectively installed with edge mounting plates 203, which are connected and fixed to the edge mounting part 134 of the flange 13 by screws or snaps, thereby further improving the stability of the connection between the heat exchanger 200 and the disk body 10. The setting of the edge mounting part 134 also facilitates the alignment of the heat exchanger 200 on the disk body 10 during installation, thereby improving the installation efficiency.

[0095] 5 , 14 , and 16 , the air conditioner chassis structure 100 further includes a protective plate 40, which is sandwiched between the edge mounting portion 134 and the edge mounting plate 203. The protective plate 40 may be made of an elastic material such as silicone to avoid hard contact between the edge mounting portion 134 and the edge mounting plate 203, thereby ensuring the service life of both.
