The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0031] like Figure 1 and Figure 3 As shown, in a first aspect, embodiments of this application provide a heat exchanger end plate 1 for installation on one end of a heat exchanger 2 along a first direction, which can simplify the assembly structure and assembly process and improve assembly efficiency.

[0032] The heat exchanger end plate 1 is provided with multiple rows of through holes 11, each row of through holes 11 including at least one through hole 11; for example, each row of through holes 11 may include multiple through holes 11, which are used to pass through the heat exchange tubes of the heat exchanger 2. In some embodiments, the multiple rows of through holes 11 may be arranged sequentially at intervals along a second direction, and each row of through holes 11 may include multiple through holes 11 arranged sequentially at intervals along a third direction, with adjacent rows of through holes 11 staggered. The first direction is perpendicular to the second direction and the third direction, respectively, and the second direction and the third direction are arranged perpendicularly or obliquely.

[0033] In each row of through holes 11, at least one through hole 11 has an elastic buckle 112 on its side wall, which is used to hold the heat exchange tube in place. For example, in the same row of through holes 11, each through hole 11 has an elastic buckle 112 on its side wall. For another example, in the same row of through holes 11, only some through holes 11 have an elastic buckle 112 on their side walls, while the side walls of the remaining through holes 11 do not have an elastic buckle 112.

[0034] In this configuration, the elastic clips 112 in any row of through-holes 11 are staggered with those in the adjacent row of through-holes 11. In other words, the elastic clips 112 arranged on the sidewalls of the multiple rows of through-holes 11 form multiple rows of elastic clips 112. Any two adjacent rows of elastic clips 112 are staggered along the third direction (the arrangement direction of the elastic clips 112 in the same row). One elastic clip 112 in the front row and one elastic clip 112 in the back row are distributed along a fourth direction, which is angled to the second and third directions, respectively, ensuring that the elastic clip 112 in the back row is not obstructed by the elastic clip 112 in the front row. The first direction, as mentioned above, is the length direction of the heat exchanger 2.

[0035] Compared with related technologies, the heat exchanger end plate 1 provided in this application embodiment has elastic buckles 112 on the side wall of at least some of the through holes 11 in each row of through holes 11, and any two adjacent rows of elastic buckles 112 are staggered. Multiple rows of elastic buckles 112 are used to reliably lock and fix the heat exchange tubes located at different positions in the heat exchanger 2. In this way, the installation structure between the heat exchanger 2 and the heat exchanger end plate 1 is more reliable, and no or only a small number of fixing screws are needed, as well as no or only a small number of fixing straps are needed. This can reduce the number of fixing screws and screw assembly steps, the number of fixing straps and strap binding steps required for assembly, thereby simplifying the assembly structure and assembly process and improving assembly efficiency.

[0036] The number of rows of through holes 11 can be determined according to actual needs, and this application embodiment does not limit this. In some embodiments, the heat exchanger end plate 1 may be provided with at least three rows of through holes 11, and the elastic buckles 112 in the two rows of through holes 11 with a difference of two rows are aligned. In other words, in the three rows of through holes 11, the elastic buckles 112 in the two rows of through holes 11 on both sides, that is, the two rows of elastic buckles 112 on both sides, are aligned along the third direction of the arrangement of the elastic buckles 112 in the same row; in this way, one elastic buckle 112 in the front row and one elastic buckle 112 in the back row are distributed along the second direction, so that the elastic buckle 112 in the back row will not be blocked by the elastic buckle 112 in the front row. With the above arrangement, the two rows of elastic buckles 112 on both sides can be locked and fixed to the heat exchanger 2 from the corresponding positions on both sides of the heat exchanger 2, increasing the connection reliability between the heat exchanger end plate 1 and the heat exchanger 2.

[0037] In some embodiments, the orientation of the elastic clips 112 in at least two adjacent rows of through holes 11 can be set to opposite directions. In this way, at least two adjacent rows of elastic clips 112 can be respectively locked onto two heat exchange tube sections located on both sides of the heat exchanger 2 to achieve reliable locking and fixing.

[0038] In some embodiments, the orientation of the elastic clips 112 in at least two adjacent rows of through holes 11 can be set to the same direction. In this way, at least two adjacent rows of elastic clips 112 can be reliably locked onto different heat exchange tube sections in the heat exchanger 2 in sequence with the same orientation.

[0039] In some embodiments, the elastic clips 112 in a row of through holes 11 near the edge of the heat exchanger end plate 1 can be disposed towards the edge of the heat exchanger end plate 1, and the elastic clips 112 in a row of through holes 11 near the middle of the heat exchanger end plate 1 can be disposed towards the middle of the heat exchanger end plate 1. In this way, the elastic clips 112 in a row of through holes 11 near the edge of the heat exchanger end plate 1 can be engaged with the heat exchange tube section located on one side edge of the heat exchanger 2, and the elastic clips 112 in a row of through holes 11 near the middle of the heat exchanger end plate 1 can be engaged with the heat exchange tube section located on the other side edge of the heat exchanger 2, thereby achieving reliable engagement and fixation through a multi-point engagement structure.

[0040] The structure of the heat exchange tube can be determined according to actual needs, and the embodiments of this application do not limit it. In some embodiments, the heat exchange tube may have a U-shaped tube section; correspondingly, the through hole 11 may be a waist-shaped hole, and the through hole 11 is suitable for inserting the U-shaped tube section.

[0041] The construction of the through hole 11 can be determined according to actual needs, and this application embodiment does not limit it. In some embodiments, the through hole 11 can be a flanged hole, and the flange 111 of the flanged hole is formed on the side surface of the heat exchanger end plate 1 away from the heat exchanger 2.

[0042] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, the bottom of the heat exchanger end plate 1 may be provided with a window 13, which extends vertically through the heat exchanger end plate 1. When a water receiving tray 3 is provided on the lower side of the heat exchanger end plate 1, the window 13 and the drain nozzle 31 of the water receiving tray 3 are correspondingly arranged. In this way, it is possible to observe whether the drain nozzle 31 of the water receiving tray 3 is blocked through the window 13, and to clear the blockage of the drain nozzle 31 through the window 13 when the drain nozzle 31 is blocked, so that the drain nozzle 31 is unobstructed; in this process, it is not necessary to disassemble the entire equipment where the heat exchanger 2 is located, thus improving the convenience of maintenance.

[0043] like Figure 5As shown, in some embodiments, a protective flange 12 may be provided on the surface of the heat exchanger end plate 1 facing the heat exchanger 2. When the heat exchanger end plate 1 and the heat exchanger 2 are connected, the protective flange 12 covers the end of the heat exchanger 2. In this way, the protective flange 12 can shield and protect the sharp parts of the end of the heat exchanger 2, such as fins, preventing operators or other objects from being scratched by the sharp parts.

[0044] like Figures 1 to 6 As shown, in a second aspect, embodiments of this application provide a heat exchanger assembly, which includes a heat exchanger 2 and a heat exchanger end plate 1 as described in any of the above embodiments. The heat exchanger end plate 1 is mounted on one end of the heat exchanger 2 along a first direction. The heat exchanger assembly provided in this application, having the aforementioned heat exchanger end plate 1, can simplify the assembly structure and assembly process, and improve assembly efficiency.

[0045] In some embodiments, the heat exchanger assembly may include two heat exchanger end plates 1, which are respectively mounted on opposite ends of the heat exchanger 2 along a first direction. In some examples, the heat exchanger assembly may include a connecting strip 4, one end of which can be snapped into one of the heat exchanger end plates 1 located at one end, and the other end of which can be snapped into or fixed to the heat exchanger end plate 1 located at the other end by screws. Exemplarily, the heat exchanger end plate 1 is provided with a hook hole 14, and at least one end of the connecting strip 4 is provided with a hook portion 41, which hooks into the hook hole 14.

[0046] like Figures 1 to 6 As shown, in a third aspect, embodiments of this application provide an air conditioner that includes the heat exchanger assembly described above. The type of air conditioner can be determined according to actual needs, and may include, for example, a wall-mounted air conditioner, a cabinet air conditioner, a ceiling-mounted unit, etc. Embodiments of this application do not limit this type. The air conditioner provided in this application, having the aforementioned heat exchanger assembly, simplifies the assembly structure and assembly process, and improves assembly efficiency.

[0047] The heat exchanger end plate, heat exchanger assembly, and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
