[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] The following is combined Figures 1-3 This utility model describes an evaporator tube sheet for mounting an evaporator on a frame 100. The evaporator tube sheet includes a tube sheet body 1, a frame connecting structure 2, and a cover connecting structure 3.

[0045] The tube sheet body 1 is used to limit the evaporator, which can accurately define the installation position of the evaporator in the air conditioning system, prevent the evaporator from shifting due to vibration and other factors during air conditioning operation, ensure the relative position of the evaporator and other components, and enable the evaporator to perform its heat exchange function stably and efficiently.

[0046] Both the frame connection structure 2 and the casing connection structure 3 are mounted on the tube sheet body 1. The frame connection structure 2 connects the tube sheet body 1 to the frame 100; the casing connection structure 3 connects the tube sheet body 1 to the casing, so that the tube sheet body can both fix the evaporator and simultaneously connect the frame 100 and the casing, ensuring that the frame 100 and the casing are integrated. In other words, the tube sheet body 1 achieves an integrated connection of the evaporator, frame 100, and casing, reducing the risk of loosening due to too many connection points, ensuring a tight integration of the frame 100 and the casing, enhancing the rigidity and stability of the overall air conditioning structure, extending the service life of the air conditioner, and better protecting internal components from external impacts during transportation and handling.

[0047] In addition, the tube sheet body 1 integrates the functions of evaporator limiting, frame 100, and cover connection, which avoids occupying too much space due to the use of multiple connection structures and makes the internal structure of the air conditioner more compact. At the same time, it makes the fit between the evaporator, frame 100, and cover tighter, reduces the problem of air leakage caused by connection gaps, and enhances the sealing performance of the system.

[0048] In one feasible embodiment of this utility model, the cover connection structure 3 includes a support part 31 and a fixing part 32. The support part 31 is connected to the tube sheet body 1, providing a stable support foundation for the cover. During air conditioning operation, under vibration conditions, the support part 31 can effectively disperse the external force borne by the cover, preventing deformation or loosening of the cover due to concentrated external force. The fixing part 32 is connected to the support part 31, and a fixing hole 33 is provided on the fixing part 32 for fasteners to pass through. The fixing hole 33 provides a precise installation position for the fasteners, enabling the cover to be quickly positioned during assembly. The combined connection of the support part 31, the fixing part 32, and the tube sheet body 1 allows the force on the cover to be evenly distributed across the entire connection structure. Compared to single-point connections or simple overlaps, this effectively avoids local stress concentration.

[0049] In one feasible embodiment of this utility model, the housing connection structure 3 further includes a reinforcing part 34, which is disposed on one side of the supporting part 31 and connected to the tube sheet body 1. During air conditioner operation, especially under extreme conditions, the reinforcing part 34 can share the pressure and shear force borne by the supporting part 31, effectively preventing the supporting part 31 from bending or deforming due to excessive force. The addition of the reinforcing part 34 changes the stress distribution path, redistributing the stress concentrated at the connection between the supporting part 31 and the tube sheet body 1, reducing local stress concentration. The reinforcing part 34 can be designed to be lightweight according to the actual space layout, enhancing structural strength without occupying too much internal space of the air conditioner, ensuring the compactness of the overall air conditioner structure. In addition, the presence of the reinforcing part 34 further improves the stability of the connection structure, making the positioning of the fixing part 32 and the fixing hole 33 more accurate during assembly, ensuring the accuracy of fastener installation even in complex assembly environments, and improving assembly efficiency.

[0050] In one feasible embodiment of this utility model, a water-blocking rib 4 is also provided on the tube sheet body 1. During air conditioner operation, a large amount of condensate is generated on the evaporator surface. The water-blocking rib 4 forms a physical barrier on the tube sheet body 1, effectively altering the flow path of the condensate. When the condensate flows along the evaporator surface to the tube sheet body 1, the water-blocking rib 4 blocks the water flow, preventing condensate from dripping directly onto other components inside the air conditioner or spreading in unexpected directions. This prevents short circuits in electrical components and corrosion of metal parts caused by condensate leakage, thus improving the safety and stability of the air conditioner operation.

[0051] It should be noted that if condensate flows freely, it may seep into critical components such as the air conditioner motor and circuit board, accelerating component aging and damage. The water-blocking rib 4 guides the condensate to a designated drainage channel, allowing it to drain smoothly outside the air conditioner. This reduces moisture corrosion of internal components, effectively protecting the delicate electronic components and metal structures inside the air conditioner, lowering the probability of malfunctions caused by moisture corrosion, extending the overall lifespan of the air conditioning equipment, and reducing later maintenance costs.

[0052] In one feasible embodiment of this utility model, there are multiple water-blocking ribs 4, and the multiple water-blocking ribs 4 are arranged in parallel. The parallel water-blocking ribs 4 form a flow guide channel, which can perform secondary distribution of condensate. The width and slope of the flow guide channel can be precisely designed according to the drainage requirements, so that the water flow forms a laminar flow state in the channel, reducing turbulence resistance and accelerating the drainage speed.

[0053] In one feasible embodiment of this utility model, the tube sheet body 1 includes a cover plate 11 and a limiting structure 12. The limiting structure 12 is disposed on the side of the cover plate 11 facing the evaporator, and both sides of the limiting structure 12 extend beyond the sidewalls of the cover plate 11. The limiting structure 12, disposed on the side of the cover plate 11 facing the evaporator, can precisely match the outer contour of the evaporator, limiting the evaporator from multiple directions to ensure that the evaporator is in a precise position during installation, avoiding the impact of installation deviations on heat exchange efficiency. The limiting structure 12 extending beyond the sidewalls of the cover plate 11 increases the contact area and force range with the evaporator, making the fixing force on the evaporator more evenly distributed.

[0054] In a feasible embodiment of this utility model, the skeleton connection structure 2 includes a first connecting part 21, a second connecting part 22, and a third connecting part 23. The first connecting part 21 is disposed on one side of the cover plate; the second connecting part 22 and the third connecting part 23 are both disposed on the limiting structure 12; and cylindrical holes are provided on the first connecting part 21, the second connecting part 22, and the third connecting part 23. The first connecting part 21, the second connecting part 22, and the third connecting part 23 are respectively disposed on the cover plate 11 and the limiting structure 12, forming a spatial three-dimensional connection layout. When the air conditioner is subjected to external impact, vibration, or internal pressure changes, the three connecting parts work together to distribute the external force on the skeleton evenly to different parts of the tube sheet body 1. Compared with a single connection point or planar connection method, this structure can improve the load-bearing capacity of the connection parts.

[0055] In one feasible embodiment of this utility model, hollow reinforcing structures 5 are provided on both sides of the cover plate. The hollow reinforcing structures 5 significantly reduce the weight of the cover plate by removing material from non-critical stress areas.

[0056] The second aspect of this utility model is to provide an indoor air conditioning unit, including an evaporator, a frame, a casing, and an evaporator tube plate as described above.

[0057] The air conditioner indoor unit provided by this utility model has the above-mentioned advantages because it includes the evaporator tube plate as described above.
