Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an outdoor unit for an air conditioner. Background Technology

[0002] The heat exchanger is one of the key components of an air conditioner's outdoor unit, primarily responsible for the transfer and exchange of heat. The heat exchanger in the outdoor unit works in conjunction with the heat exchanger in the indoor unit, transferring heat through the circulation of refrigerant to complete the air conditioner's cooling or heating cycle, ensuring the efficient and stable operation of the air conditioning system.

[0003] In some outdoor air conditioning units, especially those with larger capacity, the heat exchanger is typically a multi-row structure. In existing technology, the end of the heat exchanger extending towards the compressor is usually connected to the casing via bolts or other fasteners, while the end of the heat exchanger furthest from the compressor has less constraint on the casing. This results in gaps of varying distances between each row of heat exchangers. When the airflow speed through the heat exchanger is high, air can leak out through these gaps, leading to lower efficiency of the outdoor air conditioning unit's heat exchanger. Furthermore, when the gaps between different rows of heat exchangers are large, a whistling sound can be produced. This high-frequency noise is likely to cause user complaints.

[0004] Therefore, in the existing technology, the installation method of heat exchangers cannot well meet the requirements of air conditioner outdoor units. Utility Model Content

[0005] To address the shortcomings of related technologies, this application provides an air conditioner outdoor unit that uses a limiting member at the bottom of the casing to limit the heat exchanger, thereby constraining the size of the heat exchanger from the leeward side to the windward side, thus avoiding excessive gaps between the heat exchange fins that could cause adverse effects.

[0006] This application provides an outdoor unit for an air conditioner, comprising:

[0007] The housing includes a housing air inlet and a housing air outlet. The housing air inlet is located on the outer periphery of the housing, and the housing air outlet is located on the front side of the housing.

[0008] The fan is located inside the casing, with its outlet facing the air outlet of the casing.

[0009] The heat exchanger is located inside the casing, with its windward side facing the air inlet of the casing and its leeward side facing the air inlet of the fan; the windward side of the heat exchanger is in contact with the side wall of the casing.

[0010] The compressor, located inside the casing, is used to drive the flow of refrigerant within the heat exchanger;

[0011] The heat exchanger further includes:

[0012] Multiple heat exchange fins are arranged from the windward side to the leeward side of the heat exchanger; the heat exchange fins are arranged along the height of the heat exchanger.

[0013] The limiting component is located on the bottom surface of the casing and inside the casing. The limiting component is in contact with the lower end of the leeward side of the heat exchanger.

[0014] This technical solution uses a limiting component to make it contact the leeward side of the heat exchanger. By using the cooperation between the limiting component and the inner wall of the casing, the dimensions of the heat exchanger from the leeward side to the windward side are effectively constrained, preventing excessive gaps between multiple heat exchange fins, ensuring a tight arrangement of heat exchange fins, thereby improving heat exchange efficiency, reducing air leakage, and enhancing the structural stability and overall performance of the heat exchanger.

[0015] In some embodiments, the heat exchanger includes:

[0016] The first section extends along the length of the casing; one end of the first section is positioned towards the compressor.

[0017] The second section extends along the thickness of the casing, with the end of the second section furthest from the first section facing the front of the casing.

[0018] At least two limiters are required, with the two limiters corresponding to the first and second segments.

[0019] This technical solution increases the constraint effect of the limiting components on the heat exchanger by setting limiting components in the first and second sections, thereby enhancing the structural stability of the heat exchanger and preventing displacement or vibration during operation, thus improving the reliability and service life of the equipment.

[0020] In some embodiments, the heat exchanger further includes a bending section, with its two ends correspondingly connected to the first and second sections, and the bending section is used to change the extension direction of the heat exchanger; at least one limiting member is provided at the bending section.

[0021] This technical solution increases the heat exchanger's heat exchanger area and thus its heat exchange efficiency by adding a bending section to the heat exchanger, thereby changing the heat exchanger's extension direction and keeping the casing size unchanged. Furthermore, by placing three limiting members at the lower ends of the first, bending, and second sections respectively, the constraint effect of the limiting members on the heat exchanger is enhanced, improving the structural stability of the heat exchanger and preventing displacement or vibration during operation, thereby improving the equipment's reliability and service life.

[0022] In some embodiments, the upper end of the limiting member facing the heat exchanger is defined by a first plane, and the leeward side of the heat exchanger is defined by a reference plane; the first plane and the reference plane together define an included angle α, which satisfies: α≥15°, α≤50°.

[0023] This technical solution ensures that α ≥ 15° and α ≤ 50°, so that the upper end of the limiting component provides a sufficient tilt angle for the installation of the heat exchanger. This allows the heat exchanger to be inserted more smoothly into the lower end of the limiting component and engage with it, reducing jamming or obstruction caused by insufficient angle during installation.

[0024] In some embodiments, the lower end of the limiting member facing the heat exchanger defines a second plane, which intersects with the first plane; the second plane and the reference plane together define an included angle β, and the included angle β and included angle α satisfy: α > β.

[0025] This technical solution makes α > β to facilitate the placement of the heat exchanger within the second limiting part. During the heat exchanger installation process, the larger included angle α provides a wider installation entrance, while the smaller included angle β is used for precise positioning, allowing the heat exchanger to be placed quickly and accurately within the installation part.

[0026] In some of these embodiments, the included angle α satisfies: α≥25°, α≤50°; and the included angle β satisfies: β≥0°, β≤10°.

[0027] This technical solution ensures that α≥25°, α≤50°, β≥0°, and β≤10°, so that the upper end of the limiting component provides a sufficient tilt angle for the installation of the heat exchanger. This allows the heat exchanger to be inserted more smoothly into the lower end of the limiting component and engage with it, reducing jamming or obstruction caused by insufficient angle during installation. Furthermore, it allows the lower end of the limiting component to fit more closely with the leeward side of the heat exchanger, further optimizing the installation accuracy.

[0028] In some embodiments, the limiting member is provided with a ventilation section for air to pass through the limiting member and come into contact with the heat exchanger.

[0029] This technical solution reduces airflow resistance by incorporating a ventilation section in the limiting component, allowing air to pass through the limiting component and contact the heat exchanger, thus reducing the obstruction of the heat exchanger by the limiting component.

[0030] In some embodiments, a support member is provided on the side of the limiting member away from the heat exchanger, and the support member is used to support the limiting member; the lower end of the support member is connected to the bottom surface of the housing, and the upper end of the support member is connected to the side of the limiting member away from the heat exchanger.

[0031] This technical solution increases the stability of the limiting component by setting a support component to support the limiting component, thereby enabling the limiting component to have a better constraint effect on the heat exchanger.

[0032] In some embodiments, the tilt direction of the support is opposite to the tilt direction of the limiting member toward the heat exchanger side.

[0033] This technical solution makes the tilting direction of the support member opposite to the tilting direction of the limiting member towards the heat exchanger, so that the support member and the limiting member together form a triangular structure, which increases the supporting effect of the support member on the limiting member, and allows the limiting member to have a better constraint effect on the heat exchanger.

[0034] In addition, this application also provides an outdoor unit for an air conditioner, comprising:

[0035] The housing includes a housing air inlet and a housing air outlet. The housing air inlet is located on the outer periphery of the housing, and the housing air outlet is located on the front side of the housing.

[0036] The fan is located inside the casing, with its outlet facing the air outlet of the casing.

[0037] The heat exchanger is located inside the casing, with its windward side facing the air inlet of the casing and its leeward side facing the air inlet of the fan.

[0038] The compressor, located inside the casing, is used to drive the flow of refrigerant within the heat exchanger;

[0039] The heat exchanger further includes:

[0040] The heat exchanger is configured with multiple heat exchange fins, which are arranged from the windward side of the heat exchanger to the leeward side of the heat exchanger.

[0041] Multiple limiting elements are provided, and the multiple limiting elements are arranged along the extension direction of the heat exchanger; the multiple limiting elements and the side wall of the casing together define the mounting part for installing the heat exchanger.

[0042] This technical solution sets up limiting components, and sets up multiple limiting components, so that the multiple limiting components are arranged along the extension direction of the heat exchanger, so that the multiple limiting components and the side wall of the casing together define the mounting part, constrain the size of the heat exchanger, and thus prevent the gap between multiple heat exchange plates from being too large.

[0043] In the above embodiments, an outdoor air conditioning unit incorporates a limiting member at the bottom of its casing. This limiting member contacts the lower end of the heat exchanger on the leeward side. The interaction between the limiting member and the inner wall of the casing effectively constrains the dimensions of the heat exchanger from the leeward side to the windward side. This prevents excessive gaps between multiple heat exchange fins, ensuring a tight arrangement and thus improving heat exchange efficiency. Simultaneously, the tightly arranged heat exchange fins reduce air leakage, enhance the structural stability of the heat exchanger, and comprehensively improve overall performance, providing a strong guarantee for the efficient and stable operation of the air conditioner.

[0065] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0066] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0067] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0068] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0069] The outdoor unit of the air conditioner provided in this application can have various implementation forms. For example... Figures 1-13 This is one specific implementation of the outdoor unit of the air conditioner in this application.

[0070] like Figure 1 As shown, the outdoor unit of the air conditioner provided in this application includes a housing 100, which forms the overall appearance of the outdoor unit. The top and bottom of the housing 100 are opposite ends, and the height direction of the housing 100 is from the top to the bottom. The left and right sides of the housing 100 are opposite sides, and the length direction of the housing 100 is from the left to the right. The front and rear sides of the housing 100 are opposite sides, and the thickness direction of the housing 100 is from the front to the rear.

[0071] like Figure 2 As shown, the housing 100 includes a top plate 110, which is located at the top of the housing 100 and forms the top surface of the housing 100.

[0072] like Figure 3 As shown, the housing 100 includes a bottom plate 140, which is located at the bottom of the housing 100 and forms the bottom surface of the housing 100; the bottom plate 140 and the top plate 110 are arranged opposite to each other along the height direction of the housing 100.

[0073] like Figure 2 As shown, the housing 100 includes a front panel 120, which is located on the front side of the housing 100 and forms the front side surface of the housing 100.

[0074] The housing 100 includes a rear side panel located at the rear of the housing 100, which forms the rear side surface of the housing 100. It should be noted that in some embodiments, the housing 100 may not include a rear side panel to increase the air intake volume of the outdoor unit of the air conditioner.

[0075] like Figures 2-3 As shown, the housing 100 includes a first side plate 130, which is located on the left or right side of the housing 100 and is used to form the left or right side of the housing 100.

[0076] The housing 100 includes a second side plate, which is disposed opposite to the first side plate 130 along the length of the housing 100; the second side plate is located on the left or right side of the housing 100 and is used to form the left or right side of the housing 100.

[0077] It should be noted that the first side plate 130 and the second side plate are respectively located on different sides of the casing 100 in the length direction. In this embodiment, the first side plate 130 is located on the left side of the casing 100, the second side plate is located on the right side of the casing 100, and part of the casing air outlet 102 is located on the second side plate.

[0078] like Figure 3 As shown, the housing 100 includes a partition 150, which is located inside the housing 100. The partition 150 is arranged along the height direction of the housing 100 and divides the interior of the housing 100 into a first chamber and a second chamber.

[0079] like Figure 1 As shown, the housing 100 includes a housing air inlet 101, which is connected to the first chamber. Air from outside the housing 100 enters the housing 100 through the housing air inlet 101.

[0080] In some embodiments, the housing air inlet 101 is located on the rear side of the housing 100.

[0081] In other embodiments, the housing air inlet 101 is located on the rear side of the housing 100 and on the side wall of the first chamber away from the second chamber.

[0082] like Figure 2 As shown, the housing 100 includes a housing air outlet 102, which is located on the front side of the housing 100 and communicates with the first chamber. Air inside the housing 100 is output to the outside through the housing air outlet 102.

[0083] like Figures 2-3 As shown, the outdoor unit of the air conditioner includes a fan 300, which is located in the first chamber, with the air outlet side of the fan 300 facing the air outlet 102 of the casing. Through the operation of the fan 300, external air is introduced into the casing 100 through the casing air inlet 101 and / or air inside the casing 100 is discharged to the outside of the casing 100 through the casing air outlet 102.

[0084] In this embodiment, the fan 300 is an axial flow fan 300, and the rotation axis of the fan 300 is set along the thickness direction of the casing 100.

[0085] like Figure 1As shown, the outdoor unit of the air conditioner includes a fan cover 200, which is located at the air outlet 102 of the casing and is installed on the front panel 120. The fan cover 200 can protect the fan 300 from entering the casing 100 through the air outlet 102 and contacting the fan 300, thus affecting the normal operation of the fan 300. On the other hand, it can concentrate the air drawn in by the fan 300, thereby increasing the speed and pressure of the air and ultimately increasing the air output of the fan. In other words, the fan cover 200 can focus the air out, improve the heat dissipation effect, and make the cooling and heating effects better.

[0086] like Figures 3-5 As shown, the outdoor unit of the air conditioner includes a heat exchanger 400, which is located inside the casing 100. The heat exchanger 400 is used to exchange heat with the air passing through it. The heat exchanger 400 is placed on the base plate 140. The windward side of the heat exchanger 400 faces the air inlet 101 of the casing, and the leeward side of the heat exchanger 400 faces the air inlet side of the fan 300. The operation of the fan 300 accelerates the heat exchange between the air and the heat exchanger 400, thereby increasing the heat exchange effect of the heat exchanger 400.

[0087] In some embodiments, the windward side of the heat exchanger 400 is in contact with the side wall of the casing 100. On the one hand, the casing 100 can be used to support the heat exchanger 400, and on the other hand, the space on the leeward side of the heat exchanger 400 can be increased, which facilitates the arrangement of components such as the fan 300.

[0088] The heat exchanger 400 extends from the left side of the housing 100, through the rear side of the housing 100, to a position near the right side of the housing 100, so as to maximize the heat exchange area of ​​the heat exchanger 400 without changing the internal space of the housing 100.

[0089] like Figure 4 As shown, the heat exchanger 400 includes a first section 410, which extends along the length of the housing 100; one end of the first section 410 is positioned toward the compressor 500.

[0090] like Figure 4 As shown, the heat exchanger 400 includes a bent section 420, which is connected to the end of the first section 410 away from the compressor 500; the bent section 420 is used to change the extension direction of the heat exchanger 400.

[0091] like Figure 4 As shown, the heat exchanger 400 includes a second section 430, which extends along the thickness direction of the housing 100; the end of the second section 430 away from the bending section 420 is disposed toward the front side of the housing 100.

[0092] It should be noted that the extension direction of the first segment 410 intersects the extension direction of the second segment 430 in the horizontal plane, so that the heat exchanger 400 is roughly L-shaped. With the size of the casing 100 unchanged, the heat exchange area of ​​the heat exchanger 400 can be increased, thereby increasing the heat exchange efficiency of the heat exchanger 400.

[0093] like Figure 4 As shown, the heat exchanger 400 is connected to an end plate 440, which is located at the end of the first section 410 away from the bending section 420. The end plate 440 extends along the height direction of the casing 100. The end plate 440 is connected to the partition plate 150 so that the partition plate 150 constrains and fixes the heat exchanger 400, increasing the stability of the heat exchanger 400 installation. Furthermore, the heat exchanger 400 can support the partition plate 150 through the end plate 440, increasing the stability of the partition plate 150 connection.

[0094] In this embodiment, the end plate 440, together with the partition plate 150, the first side plate 130, the top plate 110, the bottom plate 140 and the front panel 120, define a second chamber.

[0095] like Figure 3 As shown, the outdoor unit of the air conditioner includes a compressor 500, which is located in the second chamber and connected to the base plate 140. The compressor 500 is used to drive the flow of refrigerant.

[0096] like Figure 3 As shown, the outdoor unit of the air conditioner includes an electrical control box 600, which is located near the top of the casing 100. The electrical control box 600 contains an electrical control board, which is connected to the compressor 500 and the fan 300 to control the operation of the compressor 500 and the fan 300.

[0097] The heat exchanger 400 includes heat exchange plates, which are arranged along the height of the heat exchanger 400. It should be noted that the heat exchange plates include fins and pipes. Multiple fins are arranged in a row, and the pipes are interwoven and wrapped in a row of fins. This is common knowledge in the field and will not be described in detail here.

[0098] With the same heat exchanger fin size, the more heat exchanger fins there are, the better the heat exchange effect and the higher the heat exchange efficiency of the heat exchanger 400. In air conditioners with larger horsepower, the heat exchanger 400 usually includes multiple heat exchanger fins, which are arranged from the windward side to the leeward side of the heat exchanger 400 to give the heat exchanger 400 a strong heat exchange capacity.

[0099] In the existing technology, the end of the heat exchanger 400 away from the compressor 500 lacks a fixed constraint, which easily leads to larger gaps between the heat exchange fins. When air passes through the heat exchanger 400, it can easily pass through the gaps between the heat exchange fins, reducing the heat exchange efficiency of the heat exchanger 400. Furthermore, when the gaps between the heat exchange fins are relatively large, the air passing through the gaps can also produce a whistling noise, which can easily degrade the user experience.

[0100] Based on this, in this application, by setting a limiting member 700 at the bottom of the housing 100, the limiting member 700 is made to contact the leeward side of the heat exchanger 400 to limit and constrain the heat exchanger 400, thereby avoiding excessive gaps between the heat exchange plates.

[0101] like Figures 5-8 As shown, the limiting member 700 is provided on the base plate 140 and is located inside the housing 100. The limiting member 700 is in contact with the lower end of the leeward side of the heat exchanger 400. The limiting member 700 and the inner wall of the housing 100 are used to constrain the size of the heat exchanger 400 from the leeward side to the windward side, preventing the gaps between multiple heat exchange fins from being too large, ensuring the tight arrangement between the heat exchange fins, thereby improving the heat exchange efficiency of the heat exchanger 400, reducing air leakage, and also enhancing the structural stability of the heat exchanger 400 and the overall performance of the outdoor unit of the air conditioner.

[0102] It should be noted that the dimension from the windward side to the leeward side of the heat exchanger 400 is the thickness dimension of the heat exchanger 400.

[0103] In some embodiments, such as Figure 5 As shown, at least two limiting members 700 are provided. One limiting member 700 is located at the lower end of the first segment 410, and the other limiting member 700 is located at the lower end of the second segment 430, so that limiting members 700 are provided in two extending directions of the heat exchanger 400 respectively, thereby increasing the constraint effect of the limiting members 700 on the heat exchanger 400.

[0104] It should be noted that, since the end plate 440 is connected to the end of the first section 410 near the compressor 500, in order to make the first section 410 bear force evenly, the limiting member 700 is located at the position opposite to the fan 300 of the first section 410, so as to increase the constraint effect of the limiting member 700 on the first section 410.

[0105] In other embodiments, such as Figure 7As shown, at least three limiting members 700 are provided. One limiting member 700 is located at the lower end of the first section 410, one limiting member 700 is located at the lower end of the bent section 420, and another limiting member 700 is located at the lower end of the second section 430. This is to increase the constraint effect of the limiting members 700 on the heat exchanger 400, reduce the bending deformation of the heat exchanger 400 after bending, enhance the structural stability of the heat exchanger 400, and prevent it from displacing or vibrating during operation, thereby improving the reliability and service life of the equipment.

[0106] Multiple limiting members 700, together with the left side wall and the rear side wall of the housing 100, define a mounting portion, which is arranged along the arrangement direction of the limiting members 700. When the heat exchanger 400 is installed inside the housing 100, the heat exchanger 400 is located within the mounting portion, so that the heat exchanger 400 is constrained by the mutual cooperation between the limiting members 700 and the inner wall of the housing 100, preventing the gaps between the heat exchange fins from becoming too large.

[0107] In some embodiments, in order to facilitate the heat exchanger 400 being installed in the mounting section, the limiting member 700 is inclined from bottom to top and away from the heat exchanger 400 on the side facing the heat exchanger 400, so that the distance between the limiting member 700 and the leeward side of the heat exchanger 400 increases from bottom to top, thereby facilitating the cooperation between the limiting member 700 and the heat exchanger 400.

[0108] like Figures 9-11 As shown, a reference plane 401 is defined on the leeward side of the heat exchanger 400, and a first plane 701 is defined on the upper end of the limiting member 700. The first plane 701 and the reference plane 401 together define an included angle α, which satisfies: α≥15°, α≤50°, so that the fit between the limiting member 700 and the heat exchanger 400 is more reasonable, which can ensure that the heat exchanger 400 can be smoothly installed into the installation part during the installation process, and can also avoid installation difficulties caused by the angle being too small.

[0109] If α < 10°, the contact area between the heat exchanger 400 and the limiting member 700 may be too large during installation, thereby increasing the installation resistance and possibly even jamming the heat exchanger 400, affecting the installation efficiency.

[0110] If α > 50°, it may cause uneven distribution of contact force between the limiting member 700 and the heat exchanger 400, weakening the supporting capacity of the limiting member 700 and thus reducing the limiting effect of the limiting member 700 on the heat exchanger 400.

[0111] In some embodiments of this application, such as Figure 10 As shown, the limiting member 700 includes a first limiting part 710, which is located at the upper end of the limiting member 700, and the first plane 701 is defined by the first limiting part 710.

[0112] like Figure 10 As shown, the limiting member 700 includes a second limiting part 720, which is located at the lower end of the limiting member 700 and is in contact with the leeward side of the heat exchanger 400. The second limiting part 720 defines a second plane 702, which intersects with the first plane 701. The second plane 702 and the reference plane 401 together define an included angle β, and the included angle α and included angle β satisfy: α > β.

[0113] During the installation of heat exchanger 400, the larger included angle α provides a wider installation entrance, while the smaller included angle β is used for precise positioning, allowing heat exchanger 400 to be installed quickly and accurately within the installation area.

[0114] The included angle α satisfies: α≥25°, α≤50°, so that the first limiting part 710 provides a sufficient tilt angle for the installation of the heat exchanger 400, so that the heat exchanger 400 can slide into the second limiting part 720 more smoothly, reducing the jamming or obstruction caused by insufficient angle during the installation process.

[0115] If α < 25°, the angle between the first plane 701 and the reference plane 401 is too small, which may cause the contact area between the heat exchanger 400 and the limiting member 700 to be too large during installation, thereby increasing the installation resistance and affecting the installation efficiency; the bottom of the heat exchanger 400 may be damaged during the installation process, or the heat exchanger 400 may even be stuck.

[0116] If α > 50°, it may cause uneven distribution of contact force between the limiting member 700 and the heat exchanger 400, weakening the supporting capacity of the limiting member 700 and thus reducing the limiting effect of the limiting member 700 on the heat exchanger 400.

[0117] The included angle β satisfies: β≥0°, β≤10°, so that the second limiting part 720 fits more closely when it contacts the leeward side of the heat exchanger 400.

[0118] If β > 10°, the second limiting part 720 will not fit properly against the leeward side of the heat exchanger 400, which will reduce the restraining effect of the limiting part 700 on the heat exchanger 400 and easily increase the gap between the heat exchange plates.

[0119] By ensuring α≥25°, α≤50°, β≥0°, and β≤10°, the first limiting part 710 provides a sufficient tilt angle for the installation of the heat exchanger 400, allowing the heat exchanger 400 to slide more smoothly into the second limiting part 720. This reduces jamming or obstruction caused by insufficient angle during installation and also allows the second limiting part 720 to fit more closely to the leeward side of the heat exchanger 400, further optimizing the installation accuracy.

[0120] In some embodiments, such as Figure 7 As shown, the limiting member 700 is manufactured by stamping, with the base plate 140 being stamped toward the inside of the housing 100 so that the limiting member 700 protrudes from the base plate 140.

[0121] In other embodiments, such as Figure 10 As shown, the limiting member 700 is manufactured by bending. The base plate 140 is cut to form a connecting piece on the base plate 140, and the connecting piece is bent toward the inside of the housing 100 to form the limiting member 700.

[0122] It should be noted that the thickness of the limiting part 700 produced by stamping is usually larger, while the thickness of the limiting part 700 produced by bending is usually smaller. Producing the limiting part 700 by stamping and bending does not require additional welded structural components, resulting in lower production costs and higher production efficiency.

[0123] When the limiting part 700 is produced by stamping, if the included angle α is too small, it is easy to cause the protrusion 142 to crack, making it difficult to achieve one-to-one molding.

[0124] In some embodiments, such as Figure 12 As shown, the base plate 140 is provided with a flange 141, which extends along the outer periphery of the base plate 140 and is arranged facing upwards. The lower end of the heat exchanger 400 on the windward side is in contact with the flange 141.

[0125] In some other embodiments, the flange 141 is provided with a protrusion 142, which is disposed facing the inside of the housing 100. The protrusion 142 contacts the heat exchanger 400 to reduce the contact area between the flange 141 and the heat exchanger 400, thereby reducing the mating area between the flange 141 and the heat exchanger 400 and facilitating contact between the flange 141 and the heat exchanger 400.

[0126] When the limiting member 700 comes into contact with the heat exchanger 400, the limiting member 700 will block the heat exchanger 400, which will reduce the contact area between the heat exchanger 400 and the air, thereby reducing the heat exchange effect of the heat exchanger 400.

[0127] Based on this, such as Figure 13 As shown, in some other embodiments of this application, the limiting member 700 is provided with a ventilation section 703, which is used to allow air to pass through the limiting member 700 so that the air can pass through the limiting member 700 and come into contact with the leeward side of the heat exchanger 400, thereby reducing the obstruction of the heat exchanger 400 by the limiting member 700.

[0128] In some embodiments, the ventilation section 703 is an elongated hole provided along the height direction of the heat exchanger 400, and a plurality of ventilation sections 703 are provided, and the plurality of ventilation sections 703 are arranged along the extension direction of the heat exchanger 400.

[0129] After the ventilation part 703 is installed on the limiting member 700, the strength of the limiting member 700 may be reduced, resulting in a decrease in the constraint force of the limiting member 700 on the heat exchanger 400. In order to ensure the constraint effect of the limiting member 700 on the heat exchanger 400, the limiting member 700 is connected to the support member 800. The support member 800 is located on the side of the limiting member 700 away from the heat exchanger 400. The support member 800 is used to support the limiting member 700 to increase the strength of the limiting member 700.

[0130] The lower end of the support member 800 is connected to the base plate 140, and the upper end of the support member 800 is connected to the side of the limiting member 700 away from the heat exchanger 400.

[0131] The inclination direction of the support member 800 is opposite to the inclination direction of the limiting member 700 towards the heat exchanger 400, so that the support member 800 and the limiting member 700 together form a triangular structure. By utilizing the geometric stability of the triangle, the supporting effect of the support member 800 on the limiting member 700 is increased, so that the limiting member 700 can have a better constraint effect on the heat exchanger 400, effectively dispersing the force applied to the heat exchanger 400 and avoiding structural deformation or damage caused by excessive local stress.

[0132] In some embodiments, the included angle α satisfies: α≥15°, α≤45°, to facilitate contact between the heat exchanger 400 and the second limiting part 720.

[0133] If α < 15°, the angle between the first plane 701 and the reference plane 401 is too small, which may cause the heat exchanger 400 to have an excessively large contact area with the limiting member 700 during installation, thereby increasing the installation resistance and possibly even jamming the heat exchanger 400, affecting the installation efficiency.

[0134] If α > 45°, it may cause uneven distribution of contact force between the limiting member 700 and the heat exchanger 400, weakening the supporting capacity of the limiting member 700 and thus reducing the limiting effect of the limiting member 700 on the heat exchanger 400.

[0135] The aforementioned outdoor air conditioning unit uses a limiting member 700 on the base plate 140 to contact the lower end of the heat exchanger 400 on its leeward side, thereby limiting and constraining the displacement of the heat exchanger 400 on its leeward side. A flange 141 is also provided on the base plate 140, allowing the windward side of the heat exchanger 400 to contact the flange 141, thus limiting and constraining the displacement of the heat exchanger 400 on its windward side. The cooperation between the limiting member 700 and the flange 141 constrains the thickness of the heat exchanger 400, preventing excessive gaps between the heat exchange fins and ensuring the heat exchange efficiency and effect of the heat exchanger 400.
