Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a heat exchanger assembly and an air conditioner. Background Technology

[0002] Air conditioners primarily regulate air temperature through heat exchangers. To actively respond to cost reduction and efficiency improvement initiatives, heat exchangers often employ a design that removes excess U-tubes, while still meeting performance requirements, to lower costs and increase production efficiency. However, while heat exchangers without U-tubes have a more compact structure and a lower profile, this design limits their compatibility to some extent and can also lead to problems such as air leakage, exhaust duct failure, inability to remove heat from the air, difficulty in positioning due to distance from the top cover, and easy deformation of the heat exchanger.

[0003] In related technologies, a heat exchanger support is added between the heat exchanger and the base to increase the height of the heat exchanger. However, the connection structure between the heat exchanger support, the heat exchanger, and the base is relatively complex and the installation efficiency is low, which needs to be further improved. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a heat exchanger assembly and an air conditioner.

[0005] The technical solution adopted in this application to solve the above-mentioned technical problems is as follows:

[0006] In a first aspect, this application provides a heat exchanger assembly, including: a heat exchanger body;

[0007] The base, having circumferentially extending limiting ribs on it; and

[0008] A heat exchanger support is located between the heat exchanger body and the base. The heat exchanger support includes a support shell, which defines a cavity, and a limiting rib is located inside the cavity.

[0009] Optionally, in some embodiments of this application, the limiting ribs and the bracket housing are interference-fitted; and / or, the base includes a bottom wall and a plurality of bosses on the bottom wall, the base is provided with a plurality of limiting ribs, and the plurality of limiting ribs are provided on the plurality of bosses and located in the cavity.

[0010] Optionally, in some embodiments of this application, the bracket housing is provided with a first latching part, and the base is provided with a second latching part, and the first latching part and the second latching part are engaged.

[0011] Optionally, in some embodiments of this application, a connector is provided between the heat exchanger body and the heat exchanger support for connecting the heat exchanger body and the heat exchanger support.

[0012] Optionally, in some embodiments of this application, the connector is a clip, and a crossbeam is provided on the side of the bracket housing near the heat exchanger body. A slot is defined between the crossbeam and the cavity. The slot and the cavity are connected. The clip is secured in the slot and its opening faces the heat exchanger body. The bottom of the heat exchanger body is located inside the clip.

[0013] Optionally, in some embodiments of this application, the heat exchanger bracket is provided with a drain outlet on the side near the base, and the cavity and the drain outlet are connected.

[0018] In summary, due to the adoption of the above technical solution, this application has at least the following beneficial effects:

[0019] The heat exchanger assembly provided in this application has a heat exchanger bracket located between the heat exchanger body and the base.

[0039] The technical solutions of the embodiments of this application will be clearly and comprehensively described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a unique orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as exemplary in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. 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, 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 disclosed in this application.

[0042] To facilitate understanding of the present application, the spline curves and arrows used in the reference numerals in the accompanying drawings are explained below: spline curves without arrows indicate solid parts, that is, parts with solid structures; spline curves with arrows indicate virtual parts, that is, parts without solid structures.

[0043] Firstly, please refer to Figure 1 and Figure 2This application provides a heat exchanger assembly 100, including: a heat exchanger body 10; a base 30, on which a limiting rib 311 extending circumferentially is provided; and a heat exchanger bracket 20, located between the heat exchanger body 10 and the base 30, the heat exchanger bracket 20 including a bracket housing 21, the bracket housing 21 defining a cavity, and the limiting rib 311 located in the cavity.

[0044] It should be noted that the cavity defined by the support housing 21 means that the support housing 21 has a hollow structure, and when the heat exchanger assembly 100 is in operation, the support housing 21 presents an inverted groove shape. In other words, the support housing 21 has no bottom wall, and the limiting rib 311 enters the cavity through the bottom of the support housing 21 and is connected to the support housing 21.

[0045] The heat exchanger assembly 100 provided in this application has a heat exchanger bracket 20 located between the heat exchanger body 10 and the base 30. This bracket increases the horizontal height of the heat exchanger body 10, preventing air leakage and exhaust duct failure caused by an excessively low heat exchanger body 10. Increasing the horizontal height also facilitates positioning of the heat exchanger body 10 on the side furthest from the base 30, protecting it from deformation during external impacts, long-distance transportation, or loading and unloading. The limiting ribs 311 on the base 30 provide positioning during connection with the heat exchanger bracket 20, making the installation process smoother and more precise, improving the installation efficiency of the heat exchanger bracket 20 on the base 30. The limiting ribs 311 can also engage with the cavity on the bracket housing 21 facing the base 30 for locking and securing, improving the connection stability between the heat exchanger bracket 20 and the base 30, thereby enhancing the reliability of fixing the heat exchanger body 10. Furthermore, the cavity structure of the bracket housing 21 meets functional requirements while reducing materials and production costs, achieving cost reduction and efficiency improvement.

[0046] In some embodiments of this application, please refer to Figure 3 and Figure 4 The base 30 includes a bottom wall 33 and a plurality of protrusions 31 on the bottom wall 33. The base 30 is provided with a plurality of limiting ribs 311, which are respectively provided on the plurality of protrusions 31 and located in the cavity.

[0047] Furthermore, there is a gap between the bosses 31. Several limiting ribs 311 are spaced apart along the circumference of the base 30. It can be understood that by spaced-apart limiting ribs 311, compared to a single large limiting rib 311 arranged along the entire circumference of the base 30, material waste can be reduced and the processing of the base 30 can be facilitated. The cavity between adjacent limiting ribs 311 faces the bottom wall 33 of the base 30, and there is a gap between the bottom wall 33 and the support housing 21, which is more conducive to the drainage of condensate in the cavity.

[0048] Furthermore, in some embodiments, the limiting rib 311 and the support housing 21 are interference-fitted. The interference fit has a simple structure, is easy to manufacture, and has good tightness. It can restrict the rotation of the support housing 21 on the base 30 along the circumference of the base 30. Even if it is placed upside down during handling and transportation, it can reduce the risk of the heat exchanger support 20 falling off the base 30.

[0049] In some embodiments of this application, the support housing 21 is provided with a first snap-fit ​​portion 22, and the base 30 is provided with a second snap-fit ​​portion 32, and the first snap-fit ​​portion 22 and the second snap-fit ​​portion 32 are engaged. The snap-fit ​​connection can further enhance the connection stability between the heat exchanger support 20 and the base 30.

[0050] For example, the first latching part 22 can be a latch, and the second latching part 32 can be a socket. The number, position, and shape of the sockets and latches are not limited, as long as they can cooperate with each other to form a stable connection.

[0051] Specifically, please refer to [the relevant document] again. Figure 4 In some embodiments, the opening of the insertion port of the second latching portion 32 may face towards the side away from the base 30. See also... Figure 5 In other embodiments, the opening of the second latch 32 may also face one side toward the center of the base 30.

[0052] Accordingly, please refer to Figure 6 The latch of the first latch 22 can be located on the side wall of the bracket housing 21 facing the center of the base 30, or it can be located on the side wall away from the center of the base 30.

[0053] In some embodiments of this application, please refer to Figure 7 and Figure 8 The bracket housing 21 has a flange 23 on the side near the base 30, away from the cavity, for abutting against the base 30. The flange 23 structure can prevent the bracket housing 21 from scratching the base 30 when it is connected to the base 30. When the heat exchanger bracket 20 and the base 30 are installed, if there is a small amount of condensate on the boss 31 of the base 30, the flange 23 can be adsorbed onto the boss 31 by the adsorption force of the condensate, which can further strengthen the stable connection between the heat exchanger bracket 20 and the base 30 and prevent the heat exchanger bracket 20 from falling off.

[0054] Furthermore, in some embodiments, the flange 23 is provided with an anti-slip pad on the side near the base 30. The anti-slip pad can increase the friction between the bracket housing 21 and the base 30, prevent the bracket housing 21 from moving on the base 30, provide stable support, and also protect the base 30 from wear.

[0055] Please refer to it again. Figure 8In some embodiments of this application, the heat exchanger support 20 is provided with a drain port 212 on the side near the base 30, and the cavity and the drain port 212 are connected. In other words, the drain port 212 forms a gap between the support housing 21 and the base 30. Condensate entering the cavity of the support housing 21 can be discharged to the base 30 through the drain port 212, and then discharged to the outside of the heat exchanger assembly 100. This prevents condensate generated during the operation of the heat exchanger body 10 from entering the cavity structure of the support housing 21 and being unable to be discharged, thus affecting the operation of the heat exchanger body 10.

[0056] Please see Figure 9 The support housing 21 includes an inner sidewall 213 and an outer sidewall 214 disposed opposite to each other, and a top wall 215 connecting the inner sidewall 213 and the outer sidewall 214. The inner sidewall 213, the outer sidewall 214 and the top wall 215 define a cavity, and the top wall 215 is used to connect with the heat exchanger body 10.

[0057] Furthermore, the angle formed by the extension of the top wall 215 and the outer wall 214 is the windproof angle α, where 88°≤α≤90°. Within this angle range, the heat exchanger support 20 can be stably connected to the base 30 and also serve as a windproof barrier, preventing the external environment from affecting the heat exchanger support 20.

[0058] The angle formed by the extension of the top wall 215 and the inner sidewall 213 is the water-guiding angle β, where 0° < β ≤ 90°. Preferably, 45° ≤ β ≤ 90°. It can be understood that the condensate generated during the operation of the heat exchanger body 10, in addition to entering the support shell 21 and being discharged from the cavity to the base 30, can also slide down along the side of the inner sidewall 213 away from the cavity to the base 30. The larger the water-guiding angle, the more conducive it is to the discharge of condensate.

[0059] In some embodiments of this application, a connector is provided between the heat exchanger body 10 and the heat exchanger support 20 for connecting the heat exchanger body 10 and the heat exchanger support 20.

[0060] In some embodiments of this application, the connector is a clip 24. A crossbeam 211 is provided on the side of the bracket housing 21 near the heat exchanger body 10. A slot 2111 is defined between the crossbeam 211 and the cavity. The slot 2111 communicates with the cavity. The clip 24 is fixed in the slot 2111 and the opening faces the heat exchanger body 10. The bottom of the heat exchanger body 10 is located inside the clip 24.

[0061] It should be noted that the slot 2111 and the cavity are connected. The condensate generated during the operation of the heat exchanger body 10 can enter the cavity through the slot 2111 at the bottom and be discharged from the cavity. When the heat exchanger support 20 is provided with a drain port 212 on the side near the base 30, the drain port 212 is located directly below the slot 2111. In this way, the slot 2111, the cavity, and the drain port 212 are connected in sequence to form a complete drainage channel. This facilitates the rapid discharge of the condensate generated during the operation of the heat exchanger body 10 into the cavity under the action of gravity and from the drain port 212. This protects the integrity of the heat dissipation air duct of the heat exchanger assembly 100 and prevents the fins on the heat exchanger body 10 from being soaked in condensate and rusting.

[0062] Specifically, please refer to Figure 10 The clip 24 can be a U-shaped clip. The width of the clip 24 is W, which is the installation width of the heat exchanger body 10. The width of the crossbeam 211 is A. W and A satisfy: 3mm≤A≤1 / 3W. This helps to ensure that the crossbeam 211 has a certain strength and also ensures that the clip 24 can pass smoothly through the crossbeam 211 along its width direction and be stably fixed in the slot 2111.

[0063] In some embodiments of this application, the depth of the slot 2111 is H1, that is, the vertical distance between the crossbeam 211 and the inner sidewall 213 or the outer sidewall 214 is H1, and the thickness of the clip 24 is H2. H1 and H2 satisfy: H1-H2≥0.3mm, to ensure that the clip 24 passes smoothly through the crossbeam 211 along its height direction.

[0064] In some embodiments of this application, please refer to Figure 11 The length of the slot 2111 is D1, that is, the length of the crossbeam 211 along the circumference of the heat exchanger support 20 is D1, and the length of the clip 24 along the circumference of the heat exchanger support 20 is D2. D1 and D2 satisfy: D1-D2≥0.3mm, to ensure that the clip 24 passes smoothly through the crossbeam 211 along its length direction.

[0065] It should be noted that multiple connectors may be provided, and multiple connectors are arranged on the heat exchanger support 20 along the circumference of the heat exchanger support 20 to stably fix the heat exchanger body 10.

[0066] In some embodiments of this application, the heat exchanger support 20 includes a plurality of detachably connected support segments along its circumference.

[0067] For example, please refer to Figure 12 and Figure 13The heat exchanger bracket 20 may include a first bracket segment 216 and a second bracket segment 217. The first bracket segment 216 and the second bracket segment 217 are connected by snap-fit. For example, the first bracket segment 216 has a male snap-fit ​​2161 near the side wall of the second bracket segment 217, and the second bracket segment 217 has a female snap-fit ​​2171 near the side wall of the first bracket segment 216. The male snap-fit ​​2161 and the female snap-fit ​​2171 are snapped together to form the bracket housing 21. By setting the heat exchanger bracket 20 as a detachable bracket segment, and each bracket segment having a cavity structure, it is easy to stack and store the brackets, increasing the number of heat exchanger brackets 20 that can be packed. When connecting the first snap-fit ​​part 22 and the second snap-fit ​​part 32, if the first snap-fit ​​part 22 is difficult to insert into the second snap-fit ​​part 32 on the base 30, the male snap-fit ​​2161 and the female snap-fit ​​2171 can be slightly rotated and adjusted until all the first snap-fit ​​parts 22 are inserted, achieving quick assembly and disassembly.

[0068] It should be noted that the shape of the heat exchanger support 20 can be adjusted according to the shape of the heat exchanger body 10 and the base 30, including but not limited to circular, arc, L-shaped, etc.

[0069] When assembling the heat exchanger assembly 100 provided in this application, the bracket housing 21 can be aligned with the limiting ribs 311 on the base 30 through the cavity of the bracket housing 21, and the bracket housing 21 can be placed on the boss 31 of the base 30. Then, the first snap-fit ​​part 22 of the bracket housing 21 can be inserted into the second snap-fit ​​part 32 of the base 30. During this process, male snap-fit ​​2161 and female snap-fit ​​2171 between multiple bracket segments can be provided to facilitate the insertion of all the first snap-fit ​​parts 22. After the multiple clips 24 are passed through the slots 2111 defined by the crossbeam 211 on the bracket housing 21 and placed stably, the bottom of the heat exchanger is placed in the clips 24 so that the clips 24 clamp the heat exchanger, thereby realizing the installation of the heat exchanger assembly 100.

[0070] Secondly, embodiments of this application also provide an air conditioner, which includes the heat exchanger assembly 100 described above.

[0071] It is understood that the heat exchanger body 10 in the heat exchanger assembly 100 can be a condenser or an evaporator. The heat exchanger assembly 100 provided in this application is easy to assemble and disassemble. During use, the heat exchanger bracket 20 can raise the height of the heat exchanger body 10 to reduce costs and ensure its normal operation. The heat exchanger bracket 20 is stably connected to the heat exchanger body 10 and the base 30 respectively, improving reliability. The heat exchanger bracket 20 can also promote the discharge of condensate generated by the heat exchanger body 10, extending the service life of the heat exchanger assembly 100.
