Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to an evaporator bracket, an evaporator assembly, and a refrigeration device. Background Technology

[0002] Evaporator brackets are components used to support evaporators in refrigeration equipment such as air conditioners. They are usually equipped with limiting cavities and clips. The heat exchange tubes of the evaporator pass through the limiting cavity and are engaged with the clips to be limited.

[0003] In related technologies, the clips on the evaporator bracket are either too rigid, which can cause assembly difficulties and damage the heat exchange tubes, or too soft, which can cause the clips to not be secure and to come loose.

[0004] It is evident that the evaporator brackets in related technologies often struggle to balance ease of assembly with secure positioning, and therefore require improvement. Summary of the Invention

[0005] This application aims to provide an evaporator bracket, evaporator assembly, and refrigeration equipment that can balance ease of assembly and secure positioning.

[0006] To achieve the above objectives, the evaporator support provided in this application includes:

[0007] matrix; and

[0008] A limiting part is disposed on the base and includes a limiting cavity, a first latch and a second latch. The limiting cavity is used for the heat exchange tube of the evaporator to pass through. The first latch and the second latch are disposed on the side walls of different limiting cavities of the limiting part and are used to engage with the heat exchange tube in the limiting cavity. The side wall of the limiting cavity where the first latch is located is provided with two first notches, which are located on both sides of the first latch along a first direction. The side wall of the limiting cavity where the second latch is located is provided with a second notch, which is located on one side of the second latch along a first direction. The first direction is perpendicular to the depth direction of the limiting cavity.

[0009] In some embodiments, the limiting portion is configured as at least one of the following:

[0010] The first notch does not extend to the bottom end of the side wall of the limiting cavity where the first buckle is located;

[0011] The second notch extends to the bottom end of the side wall of the limiting cavity where the second buckle is located;

[0012] The first and second buckles are arranged alternately in the first direction;

[0013] The first buckle protrudes from the side wall of the limiting cavity toward the first side in the second direction, and the second buckle protrudes from the side wall of the limiting cavity toward the second side in the second direction opposite to the first side. The second direction is perpendicular to the first direction and the depth direction of the limiting cavity.

[0014] The limiting part includes at least two first latches.

[0015] In some embodiments, the limiting cavity of the limiting part is divided into at least two groups, and the at least two groups of limiting cavities are arranged sequentially along the second direction. The first buckle and the second buckle are disposed on the sidewalls of the limiting cavities of different groups, and the second direction is perpendicular to the first direction and the depth direction of the limiting cavity.

[0016] In some embodiments, the limiting cavity of the limiting part is divided into three groups, and the three groups of limiting cavities are arranged sequentially along the second direction. The first buckle and the second buckle are disposed on the side wall of the limiting cavity in the two outermost groups of limiting cavities along the second direction.

[0017] In some embodiments, the limiting portion further includes a drainage hole that communicates with the limiting cavity to guide water in the limiting cavity to flow out of the limiting cavity.

[0018] In some embodiments, the drainage hole and the limiting cavity correspond one-to-one.

[0019] In some embodiments, the evaporator support includes at least two limiting portions.

[0020] In some embodiments, the evaporator support includes two limiting portions, and the two limiting portions are connected in a V-shape.

[0021] In some embodiments, the outer surface of the substrate is provided with protrusions, and the substrate contacts a water receiving tray for receiving condensate generated by the evaporator through the protrusions.

[0022] In some embodiments, protrusions are provided at both the upper and lower ends of the outer surface of the substrate.

[0023] In some embodiments, the protrusions at the upper and lower ends of the outer surface of the substrate are staggered along the length of the outer surface of the substrate.

[0024] In some embodiments, the evaporator support is an injection-molded evaporator support.

[0025] In addition, the evaporator assembly provided in this application includes an evaporator, and also includes an evaporator bracket according to any embodiment of this application.

[0026] In some embodiments, the evaporator assembly further includes a drip tray, and the evaporator support contacts the drip tray via protrusions located on the outer side of the base.

[0027] Furthermore, the refrigeration equipment provided in this application includes the evaporator assembly of any embodiment of this application.

[0028] In some embodiments, the refrigeration device is an air conditioner.

[0029] In this application, the evaporator bracket no longer has only clips of the same hardness, but has a first clip and a second clip with different hardness. The evaporator bracket can use the softer first clip to reduce assembly difficulty and minimize damage to the heat exchange tubes, while the harder second clip can achieve a more secure connection with the heat exchange tubes and reliably limit the position. Therefore, the evaporator bracket can balance ease of assembly and secure positioning.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0044] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0045] In the description of this application, it should be understood that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0046] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0047] Figures 1-6 An exemplary schematic diagram of the evaporator assembly and its support structure in this application is shown.

[0048] in, Figure 1 and Figure 2 The structure of the evaporator assembly in this application is illustrated by way of example.

[0049] See Figure 1 and Figure 2 In this application, the evaporator assembly 100 is a component of refrigeration equipment such as an air conditioner, and includes an evaporator 20 and an evaporator support 10. The evaporator 20 is mounted on the evaporator support 10 and supported by the evaporator support 10. See also... Figure 1 and Figure 2 In some embodiments, the evaporator assembly 100 further includes a drip tray 30. The drip tray 30 is used to receive condensate produced by the evaporator 20. Typically, the drip tray 30 is positioned below the evaporator 20 and in contact with the evaporator support 10.

[0050] Figures 3-6 The structure of the evaporator support in this application is further illustrated.

[0051] See Figures 3-6 and combined Figure 1 and Figure 2 As can be seen from this application, the evaporator support 10 includes a base 1 and a limiting part 2. The limiting part 2 is disposed on the base 1 and includes a limiting cavity 21, a first latch 22, and a second latch 23. The limiting cavity 21 is used for the heat exchange tube 201 of the evaporator 20 to pass through. The first latch 22 and the second latch 23 are disposed on the side walls of different limiting cavities 21 of the limiting part 2, and are used to engage with the heat exchange tube 201 in the limiting cavity 21. Specifically, the side wall of the limiting cavity 21 where the first latch 22 is located has two first notches 24, which are located on both sides of the first latch 22 along a first direction. The side wall of the limiting cavity 21 where the second latch 23 is located has a second notch 25, which is located on one side of the second latch 23 along the first direction. The first direction is perpendicular to the depth direction of the limiting cavity 21.

[0052] In the above scheme, since the first buckle 22 has notches on both sides along the first direction (i.e., the first notch 24), while the second buckle 23 has a notch on only one side along the first direction (i.e., the second notch 25), the first buckle 22 can have a lower hardness than the second buckle 23. That is to say, the first buckle 22 has lower hardness and greater elasticity, while the second buckle 23 has higher hardness and lower elasticity. Compared with the second buckle 23, the first buckle 22 has lower hardness and greater elasticity. In this case, the evaporator bracket 10 no longer has only buckles of the same hardness, but has buckles of different hardness. The evaporator bracket 10 can use the softer first buckle 22 to reduce assembly difficulty and reduce damage to the heat exchange tube 201, and can use the harder second buckle 23 to achieve a more secure connection with the heat exchange tube 201 and reliably limit the position. Therefore, the evaporator bracket 10 can take into account both ease of assembly and secure positioning, which is conducive to improving the assembly efficiency of the evaporator assembly 100 and the refrigeration equipment, and improving the structural reliability of the evaporator assembly 100 and the refrigeration equipment.

[0053] Among them, the first buckle 22 can be called the weak buckle; the second buckle 23 can be called the strong buckle.

[0054] In order to maximize the strength of the first buckle 22 while maintaining a relatively low rigidity, see [reference needed]. Figure 3 In some embodiments, the first notch 24 is configured not to extend to the bottom end of the sidewall of the limiting cavity 21 where the first snap 22 is located. In this case, the first notch 24 can be made by removing material but not reaching the bottom (or removing material but not reaching the bottom). There is a distance between the first notch 24 and the bottom end of the sidewall of the limiting cavity 21 where the first snap 22 is located. The sidewall of the limiting cavity 21 is still left below the first notch 24. In this way, the first snap 22 can be prevented from being too soft, so that the first snap 22 can have a small hardness, but not too small a hardness, but a certain strength. Thus, while facilitating the assembly of the first snap 22 with the heat exchange tube 201, the strength of the first snap 22 is maximized, and the engagement firmness of the first snap 22 with the heat exchange tube 201 is improved, so that the evaporator bracket 10 can better balance the ease of assembly and the firmness of the limiting.

[0055] In addition, in order to maximize the flexibility of the second buckle 23 while ensuring its high rigidity, see [reference needed]. Figure 3 In some embodiments, the second notch 25 is configured to extend to the bottom end of the sidewall of the limiting cavity 21 where the second snap 23 is located. In this case, the second notch 25 can be formed by removing material and removing it to the bottom (or emptying the material and removing it to the bottom, hollowing it out). There is no longer a distance between the second notch 25 and the bottom end of the sidewall of the limiting cavity 21 where the second snap 23 is located, and there is no longer a portion of the sidewall of the limiting cavity 21 below the second notch 25. In this way, the second snap 23 can be prevented from being too hard, so that the second snap 23 can have a large hardness, but not too large a hardness, and also has a certain degree of elasticity. Thus, while achieving a firm engagement between the second snap 23 and the heat exchange tube 201, the elasticity of the second snap 23 is maximized, and the assembly convenience of the second snap 23 and the heat exchange tube 201 is improved, so that the evaporator bracket 10 can better balance assembly convenience and limiting firmness.

[0056] In the foregoing embodiments, the relative arrangement of the first latch 22 and the second latch 23 in the limiting part 2 can be varied.

[0057] For example, see Figure 3 In some embodiments, the first latch 22 and the second latch 23 in the limiting part 2 are arranged alternately in the first direction. That is, in the first direction, the first latch 22 and the second latch 23 are arranged in a manner that repeats from one first latch 22 to another second latch 23, and so on. By adopting this method of alternating strong and weak latches along the first direction, the evaporator bracket 10 can better balance assembly convenience and limiting firmness, more effectively improve the assembly efficiency of the evaporator assembly 100 and the refrigeration equipment, and improve the structural reliability of the evaporator assembly 100 and the refrigeration equipment.

[0058] For example, see Figure 3 In some embodiments, the first latch 22 protrudes from the sidewall of the limiting cavity 21 toward a first side in a second direction, while the second latch 23 protrudes from the sidewall of the limiting cavity 21 toward a second side in a second direction opposite to the first side. The second direction is perpendicular to the first direction and the depth direction of the limiting cavity 21. If the first direction is referred to as the length direction of the limiting cavity 21, then the second direction can be referred to as the width direction of the limiting cavity 21. This arrangement ensures that the first latch 22 and the second latch 23 protrude in opposite directions in the second direction, meaning they can lock the heat exchange tube 201 in opposite directions, thus increasing assembly stability.

[0059] For example, see Figure 3 In some embodiments, the limiting cavity 21 of the limiting part 2 is divided into at least two groups, which are arranged sequentially along the second direction, and the first latch 22 and the second latch 23 are disposed on the sidewalls of different groups of limiting cavities 21. In this case, the first latch 22 and the second latch 23 in the same limiting part 2 are not collinear in the second direction, but are staggered. If each group of limiting cavities 21 arranged in the second direction is called a row of limiting cavities 21, then the first latch 22 and the second latch 23 in the same limiting part 2 are located on different rows of limiting cavities 21. In this case, the distribution of the first latch 22 and the second latch 23 is more reasonable, and can better balance assembly convenience and limiting firmness.

[0060] In the foregoing embodiments, the number of first latches 22 and second latches 23 in the limiting part 2 is not limited. For example, the limiting part 2 may include one, two or more first latches 22 and one, two or more second latches 23. When the limiting part 2 includes at least two first latches 22 and at least one second latch 23, it facilitates the evaporator bracket 10 to better balance assembly convenience and limiting firmness.

[0061] In practice, it has been found that the evaporator support 10 in the relevant technology, in addition to the aforementioned problems of difficulty in balancing ease of assembly and secure positioning, also suffers from water retention, which easily leads to corrosion of the heat exchange tube 201. Specifically, during the operation of the evaporator 20, condensate will be generated on the heat exchange tube 201. The corresponding condensate, especially water droplets, is difficult to flow out on its own and tends to accumulate in the limiting cavity 21, corroding the heat exchange tube 201, reducing structural reliability, and shortening service life.

[0062] To solve the problem of the aforementioned difficulty in draining the water, see [link to relevant documentation]. Figures 3-4In some embodiments, the limiting part 2 includes a drainage hole 26, which communicates with the limiting cavity 21 to guide water in the limiting cavity 21 to flow out to the outside of the limiting cavity 21. The drainage hole 26 can guide the water in the limiting cavity 21 to flow out in a timely manner, effectively preventing condensate, especially water droplets, generated by the heat exchange tube 201 from remaining in the limiting cavity 21 for a long time, thus causing corrosion of the heat exchange tube 201, thereby effectively improving structural reliability and extending service life.

[0063] When setting the drainage hole 26, see Figure 3 and Figure 4 The drainage holes 26 can correspond one-to-one with the limiting cavities 21, so that the water in each limiting cavity 21 can be discharged in time under the action of its corresponding drainage holes 26, effectively preventing corrosion of all heat exchange tubes 201 of the evaporator 20.

[0064] In the foregoing embodiments, the number of limiting portions 2 in the evaporator support 10 can be one, two, or more. For example, in some embodiments, the evaporator support 10 may include at least two limiting portions 2. In this case, the evaporator support 10 can constrain at least two sets of heat exchange tubes 201 of the evaporator 20. Furthermore, when the evaporator support 10 includes at least two limiting portions 2, the relative positional relationship of these at least two limiting portions 2 can also be varied. For example, see... Figure 3 and Figure 4 In some embodiments, the evaporator support 10 includes two limiting parts 2, and these two limiting parts 2 are connected in a V-shape. In this case, the evaporator support 10 is particularly suitable for an evaporator 20 with two sets of heat exchange tubes 201 on one side, and the two sets of heat exchange tubes 201 on one side are arranged in a V-shape (which can be simply referred to as a V-type evaporator). Of course, when the evaporator 20 adopts other structural forms such as Z-type, C-type or G-type, the evaporator support 10 can also be designed accordingly.

[0065] In practice, it has been found that the evaporator bracket 10 in the relevant technology is prone to friction with adjacent components such as the drip tray 30 due to thermal expansion and contraction during cooling or heating, generating abnormal noise. For this purpose, see [link to relevant documentation]. Figure 3-4 and combined Figures 1-2 As can be seen, in some embodiments, the outer surface of the base 1 is provided with protrusions 27, and the base 1 contacts the water receiving tray 30 through the protrusions 27. Since the protrusions 27 are provided, the contact area between the evaporator support 10 and the water receiving tray 30 can be reduced, and friction can be reduced. Therefore, the problem of abnormal noise caused by the friction between the evaporator support 10 and the water receiving tray 30 due to thermal expansion and contraction can be effectively solved.

[0066] When the outer surface of the base 1 is provided with a protrusion 27, the protrusion 27 may be provided only at one of the upper and lower ends of the outer surface of the base 1, or, see [link to relevant documentation]. Figure 6Alternatively, the protrusions 27 can be provided at the upper and lower ends of the outer surface of the base 1. When both the upper and lower ends of the outer surface of the base 1 are provided with protrusions 27, the two rows of protrusions 27 at the upper and lower ends can better support the evaporator bracket 10, making the evaporator bracket 10 more stable.

[0067] Furthermore, in an embodiment where protrusions 27 are provided at both the upper and lower ends of the outer surface of the substrate 1, see [reference needed]. Figure 6 The protrusions 27 at the upper and lower ends of the outer side of the base 1 can be staggered along the length of the outer side of the base 1. In this case, the protrusions 27 at the upper and lower ends of the outer side of the base 1 are not directly opposite each other, but are staggered. The advantage is that it is convenient to open the mold and the processing is more convenient.

[0068] The evaporator bracket 10 in the aforementioned embodiments can be an injection-molded evaporator bracket, which makes the evaporator bracket 10 less prone to rusting compared to the case where the evaporator bracket 10 is a sheet metal evaporator bracket.

[0069] Next, combine Figures 1-6 The embodiments shown further illustrate this application.

[0070] like Figures 1-6 As shown, in this embodiment, the evaporator assembly 100 includes an evaporator 20, a water tray 30, and two evaporator supports 10.

[0071] The evaporator 20 is a V-shaped evaporator, with two sets of heat exchange tubes 201 on each side along its length, arranged in a V-shape between the two sets of heat exchange tubes 201 on each side. Each set of heat exchange tubes 201 includes three rows of heat exchange tubes 201, arranged sequentially along a second direction. Each row of heat exchange tubes 201 includes three heat exchange tubes 201 arranged sequentially along a first direction, resulting in each set of heat exchange tubes 201 on one side of the evaporator 20 having three rows and three columns, for a total of nine heat exchange tubes 201. In this embodiment, the heat exchange tubes 201 are copper tubes.

[0072] A drip tray 30 is located below the evaporator 20 to collect the condensate produced by the evaporator 20. Figure 1 As shown, the water receiving tray 30 is in contact with both evaporator supports 10.

[0073] Two evaporator supports 10 are disposed on both sides of the evaporator 20 along its length to support the evaporator 20 on both sides of its length and to constrain the heat exchange tubes 201 of the evaporator 20 located on both sides of its length. In this embodiment, the two evaporator supports 10 have the same structure; both are injection-molded evaporator supports and each includes a base 1 and two limiting parts 2.

[0074] The base 1 provides a mounting foundation for the two limiting parts 2 and facilitates contact between the evaporator bracket 10 and the water receiving tray 30. Figures 1-6 As shown, in this embodiment, the base 1 is generally rectangular and plate-shaped. Furthermore, two rows of protrusions 27 are provided on the outer surface of the base 1 facing the water receiving tray 30. These two rows of protrusions 27 are located at both ends (i.e., the upper and lower ends) of the height direction of the outer surface of the base 1 facing the water receiving tray 30. Each row of protrusions 27 includes at least two sets of protrusions 27 spaced apart along the length direction of the outer surface of the base 1 facing the water receiving tray 30. Simultaneously, the sets of protrusions 27 in the two rows are not directly opposite each other, but are staggered. Thus, the evaporator bracket 10 is provided with two rows of staggered protrusions 27, and these protrusions 27 form a floating support structure, which can not only stably support the evaporator bracket 10 and effectively improve the structural stability of the evaporator bracket 10, but also realize point contact between the evaporator bracket 10 and the water tray 30. This reduces the contact area between the evaporator bracket 10 and the water tray 30, thereby reducing the abnormal noise generated by the friction between the evaporator bracket 10 and the water tray 30 due to their different thermal expansion and contraction characteristics during the cooling or heating process.

[0075] Both limiting parts 2 are disposed on the base 1, and the two limiting parts 2 are connected at an angle to form a V-shape, corresponding one-to-one with the two sets of heat exchange tubes 201 on one side of the evaporator 20, so as to limit and constrain the two sets of heat exchange tubes 201 on one side of the evaporator 20. Figures 1-6 As shown, in this embodiment, both limiting portions 2 protrude from the base 1 in a direction away from the evaporator 20, and each includes three sets of limiting cavities 21. These three sets of limiting cavities 21 are arranged sequentially along the second direction, such that each limiting portion 2 includes three rows of limiting cavities 21, and each row of limiting cavities 21 includes three limiting cavities 21 arranged sequentially along the first direction. Thus, each limiting portion 2 includes three rows and three columns, for a total of nine limiting cavities 21. These three rows and three columns of nine limiting cavities 21 correspond one-to-one with the three rows and three columns of nine heat exchange tubes 201 in each group of heat exchange tubes 201 on one side of the evaporator 20, allowing the three rows and three columns of nine heat exchange tubes 201 in each group of heat exchange tubes 201 on one side of the evaporator 20 to pass through in a one-to-one correspondence.

[0076] Among them, such as Figures 3-6 As shown, in this embodiment, each limiting cavity 21 is oblong, with its length and width directions along the first and second directions, respectively, and it penetrates the evaporator support 10 along its thickness direction, such that the depth direction of the limiting cavity 21 is along the thickness direction of the evaporator support 10. During assembly with the evaporator 20, the U-shaped bend of the heat exchange tube 201 is inserted into the limiting cavity 21 and constrained by it.

[0077] And, as Figures 3-5As shown, in this embodiment, each limiting part 2 includes a first latch 22 and a second latch 23 for engaging with the heat exchange tube 201. The first latch 22 and the second latch 23 are disposed on the sidewall of the limiting cavity 21 in the two outermost sets of limiting cavities 21 along the second direction. In other words, the first latch 22 and the second latch 23 are disposed on the sidewall of the limiting cavity 21 in the two outermost rows of limiting cavities 21 along the second direction. Specifically, by... Figures 3-5 As can be seen, in this embodiment, each limiting part 2 includes two first latches 22 and one second latch 23. The two first latches 22 are disposed on the sidewalls of the limiting cavities 21 in the first row of limiting cavities 21 along the second direction, specifically on the sidewalls of the first and third limiting cavities 21 arranged sequentially along the first direction. The second latch 23 is disposed on the sidewall of the limiting cavities 21 in the third row of limiting cavities 21 along the second direction, specifically on the sidewall of the second limiting cavity 21 in the third row of limiting cavities along the first direction. Thus, the first latches 22 and the second latches 23 in each limiting part 2 are alternately arranged in the first direction and staggered in the second direction.

[0078] Among them, such as Figures 3-4 As shown, in this embodiment, the first latch 22 and the second latch 23 are disposed on one of the two sidewalls of the corresponding limiting cavity 21 arranged opposite each other along the second direction. The first latch 22 extends from the sidewall of the limiting cavity 21 toward the first side of the second direction, and both sides of the first latch 22 are provided with a first notch 24 that is not dug to the bottom. The second latch 23 extends from the sidewall of the limiting cavity 21 toward the second side of the second direction, and the second latch 23 is provided with a second notch 25 that is dug to the bottom only on one side of the first direction. Thus, the first latch 22 and the second latch 23 respectively form a weak latch and a strong latch, and the first latch 22 and the second latch 23 are arranged in opposite directions in the second direction.

[0079] By setting the limiting part 2 to include weak and strong latches, and arranging the weak and strong latches in an alternating reverse manner, the ease of assembly and the firmness of the connection between the evaporator bracket 10 and the heat exchange tube 201 can be effectively improved, so that the evaporator bracket 10 can better balance the ease of assembly and the firmness of the limiting part.

[0080] And, as Figure 3 and Figure 4As shown, in this embodiment, each limiting cavity 21 has a drainage hole 26 on one side along the first direction. The drainage hole 26 penetrates the evaporator support 10 along the thickness direction and communicates with the corresponding limiting cavity 21. In this way, the drainage hole 26 constitutes a drainage structure, which can drain the water in the limiting cavity 21 and prevent the condensate generated by the heat exchange tube 201 from remaining in the limiting cavity 21 during refrigeration, thus preventing corrosion of the heat exchange tube 201.

[0081] As can be seen, in this embodiment, the evaporator bracket 10 is an injection-molded evaporator bracket, and has a staggered, reverse-arranged strong and weak snap-fit ​​structure (first snap 22 and second snap 23), a flow-draining structure (flow-draining hole 26), and a floating support structure (protrusion 27). This can effectively solve the problems of evaporator brackets being prone to rusting, difficult to assemble, and easy to fall off, heat exchange tubes being prone to corrosion, and abnormal noises caused by thermal expansion and contraction between the evaporator bracket and the water receiving pan. This is conducive to improving assembly efficiency, increasing structural reliability, extending service life, and thus improving product quality and user experience.
