Detailed Implementation

[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0029] The following is for reference. Figures 1-10 Description of an outdoor unit 100 of an air conditioner according to an embodiment of the present utility model.

[0030] Combination Figures 1-10 As shown, the outdoor unit 100 of the air conditioner according to this utility model can mainly include: a casing 10, a compressor 20, an outdoor heat exchanger 30, and an outdoor fan 40.

[0031] The casing 10 has an air inlet 50 on its circumferential sidewalls and an air outlet 60 on its top. This increases the air intake area, ensuring sufficient outside air is drawn into the outdoor unit 100. After heat transfer occurs between the cold air entering the outdoor unit 100 and the hot air inside, the cold air warms up and becomes hot air. Hot air, being less dense, naturally rises. The air outlet 60 at the top follows this natural upward flow, reducing wind resistance and making the exhaust from the outdoor unit 100 smoother and more efficient, thus reducing fan energy consumption and noise. Furthermore, at the same airflow rate, a larger air intake area results in a lower air intake speed, further reducing wind resistance and noise.

[0032] Furthermore, the compressor 20 is housed inside the casing 10. The casing 10 not only provides physical protection and safety for the compressor 20, but also helps to reduce the noise generated by the compressor 20. It also creates a heat dissipation environment for the compressor 20, facilitating heat dissipation.

[0033] Furthermore, the outdoor heat exchanger 30 is housed within the casing 10 and connected to the compressor 20. Specifically, after the compressor 20 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas, the outdoor heat exchanger 30 is connected to the compressor 20. This not only creates a refrigerant passage between the outdoor heat exchanger 30 and the compressor 20, ensuring the normal flow of refrigerant between them, but also allows the outdoor heat exchanger 30 to dissipate heat and cool the high-temperature, high-pressure gas output by the compressor 20.

[0034] Moreover, the outdoor heat exchanger 30 is installed inside the casing 10. The casing 10 can not only provide physical protection and safety for the outdoor heat exchanger 30, but also facilitate the formation of air ducts, optimize the airflow path, and improve the heat exchange effect of the outdoor heat exchanger 30.

[0035] Furthermore, the outdoor fan 40 is used to introduce airflow from outside the casing 10 into the casing 10 through the air inlet 50, and after heat exchange by the outdoor heat exchanger 30, it is output to the outside through the air outlet 60. Specifically, the outdoor heat exchanger 30 needs to exchange heat efficiently with the outdoor air. Natural airflow alone cannot meet the heat exchange requirements of the outdoor heat exchanger 30. By setting the outdoor fan 40, a stable and reliable airflow path can be formed, which drives the outside air into the interior of the outdoor unit 100 of the air conditioner, thereby enabling the refrigerant in the outdoor heat exchanger 30 to exchange heat with the outdoor air. In this way, the outdoor fan 40 can not only guide the airflow direction, but also increase the airflow speed, thereby improving the heat exchange efficiency of the outdoor heat exchanger 30.

[0036] Furthermore, the housing 10 includes: a main housing 101 and a chassis 102.

[0037] The chassis 102 is located at the bottom of the main shell 101, and the bottom of the outdoor heat exchanger 30 abuts against the chassis 102. This not only allows the chassis 102 to serve as the mounting base for the outdoor heat exchanger 30, facilitating its installation, but also provides support for the outdoor heat exchanger 30, thereby improving its stability and reliability.

[0038] Furthermore, a positioning groove 103 is provided on the chassis 102, and a positioning protrusion 303 is provided on the bottom of the outdoor heat exchanger 30. The positioning protrusion 303 extends into the positioning groove 103 and is positioned and engaged with the positioning groove 103. Specifically, by providing a positioning groove 103 on the chassis 102 and a positioning protrusion 303 on the bottom of the outdoor heat exchanger 30, during assembly, it is only necessary to align the positioning protrusion 303 with the positioning groove 103 and then press the outdoor heat exchanger 30 downward so that the positioning protrusion 303 extends into the positioning groove 103 accordingly, thereby positioning and engaging with the positioning groove 103.

[0039] In this way, the positioning protrusion 303 and the positioning groove 103 can be positioned and matched to restrict the outdoor heat exchanger 30 from moving and rotating in the horizontal direction after assembly, thereby improving the assembly accuracy between the outdoor heat exchanger 30 and the chassis 102.

[0040] Furthermore, by matching the dimensions of the positioning protrusion 303 and the positioning groove 103, the outdoor heat exchanger 30 and the chassis 102 can be prevented from becoming loose, thereby allowing the bottom of the outdoor heat exchanger 30 to fit more tightly with the chassis 102.

[0041] Even if the bottom of the outdoor heat exchanger 30 has a raised portion before installation, by extending the positioning protrusion 303 downward into the positioning groove 103 and connecting and fixing the positioning protrusion 303 with the positioning groove 103, the raised portion of the bottom of the outdoor heat exchanger 30 can be flattened, allowing the bottom of the outdoor heat exchanger 30 to fit tightly against the chassis 102. This prevents the outdoor heat exchanger 30 from shifting due to vibration or wind load during operation. Moreover, the positioning fit between the positioning protrusion 303 and the positioning groove 103 can improve the installation accuracy of the outdoor heat exchanger 30 relative to the chassis 102 and facilitate the installation of the outdoor heat exchanger 30 in the outdoor air conditioning unit.

[0042] In addition, the structure of positioning protrusion 303 and positioning groove 103 is used for positioning and cooperation, which eliminates the need to set additional mounting holes and fasteners at the bottom of outdoor heat exchanger 30. During the assembly process of outdoor heat exchanger 30 and chassis 102, it is also not necessary to precisely align multiple mounting holes. This not only simplifies the assembly process between outdoor heat exchanger 30 and chassis 102 and improves assembly efficiency, but also helps to reduce the number of parts of outdoor unit 100 and reduce the production cost of outdoor unit 100.

[0043] Therefore, by setting a positioning groove 103 on the chassis 102 and a positioning protrusion 303 on the bottom of the outdoor heat exchanger 30, and by having the positioning protrusion 303 extend into the positioning groove 103 and engage with it, not only can the movement and rotation of the outdoor heat exchanger 30 in the horizontal direction be restricted, thus improving the assembly accuracy of the outdoor heat exchanger 30 relative to the chassis 102, but also the bottom of the outdoor heat exchanger 30 can fit more tightly with the chassis 102.

[0044] In some embodiments of this utility model, the outdoor fan 40 is provided with a top cover on its upper side, and the top cover is provided with multiple air outlet slots. The top cover is connected to both the outdoor heat exchanger 30 and the main housing 101.

[0045] In this way, the top cover can not only guide the direction of the airflow from the air outlet 60, so that the airflow is concentrated and discharged along the preset air duct, and prevent the airflow from the air outlet 60 from spreading, thus preventing the generation of eddies and turbulence inside the outdoor unit 100 of the air conditioner, but also prevent foreign objects from being sucked into the interior of the outdoor unit 100 of the air conditioner through the air outlet 60, which could cause problems such as damage to the impeller of the outdoor fan 40, motor jamming, or blockage of the outdoor heat exchanger 30. At the same time, it can also prevent users or maintenance personnel from accidentally coming into contact with the high-speed rotating impeller, thereby improving the safety of the outdoor unit 100 of the air conditioner.

[0046] Combination Figure 1 , Figure 5 , Figure 6 and Figure 9As shown, the outdoor heat exchanger 30 is arc-shaped and extends circumferentially along the casing 10, and the positioning protrusion 303 is disposed at the bottom of at least one end of the outdoor heat exchanger 30 in the circumferential direction.

[0047] Specifically, making the outdoor heat exchanger 30 arc-shaped not only allows it to better match the circular fan and annular duct, but also prevents stress concentration in the outdoor heat exchanger 30 due to sharp corners. Furthermore, the airflow path under the action of the fan is also arc-shaped or annular, making the outdoor heat exchanger 30 arc-shaped, which allows the air to flow more smoothly over the surface of the outdoor heat exchanger 30, reducing airflow separation and eddy current losses, and thus improving the heat exchange efficiency of the outdoor heat exchanger 30.

[0048] Furthermore, a positioning protrusion 303 is provided at the bottom of at least one end of the outdoor heat exchanger 30 in the circumferential direction, which can make the bottom of the outdoor heat exchanger 30 fit more tightly with the chassis 102, thereby improving the stability and reliability of the outdoor heat exchanger 30 and improving the installation accuracy of the outdoor heat exchanger 30.

[0049] In some embodiments of this utility model, positioning protrusions 303 can be provided not only at the bottom of one or both circumferential ends of the outdoor heat exchanger 30, but also multiple positioning protrusions 303 can be provided circumferentially at the bottom of the outdoor heat exchanger 30 to further improve the compactness and stability between the outdoor heat exchanger 30 and the chassis 102.

[0050] Combination Figure 1 , Figure 5 , Figure 6 and Figure 9 As shown, positioning protrusions 303 are provided at the bottom of both circumferential ends of the outdoor heat exchanger 30. Specifically, by providing positioning protrusions 303 at the bottom of both circumferential ends of the outdoor heat exchanger 30, compared to providing positioning protrusions 303 only at one circumferential end of the outdoor heat exchanger 30, the bottom of the outdoor heat exchanger 30 can fit more tightly with the chassis 102, more effectively preventing displacement or loosening of the outdoor heat exchanger 30 relative to the chassis 102, further improving the stability and reliability of the outdoor heat exchanger 30, and further improving the installation accuracy of the outdoor heat exchanger 30.

[0051] Combination Figure 4 , Figure 5 and Figure 6 As shown, the outdoor heat exchanger 30 includes: a heat exchange body 301 and an end plate 302.

[0052] The heat exchanger body 301 is arc-shaped and extends circumferentially along the casing 10. Specifically, the heat exchanger body 301 includes multiple U-shaped tubes. This arc shape and circumferential extension of the heat exchanger body 301 allows it to fit snugly against the inner wall of the casing 10, thereby improving not only the space utilization and structural compactness of the outdoor unit 100, but also optimizing the heat exchange area of ​​the outdoor heat exchanger 30 and enhancing its heat exchange effect. Furthermore, the arc-shaped structure enhances the structural strength and stability of the heat exchanger body 301, preventing stress concentration issues caused by sharp corners.

[0053] Furthermore, end plates 302 are installed over both circumferential ends of the heat exchanger body 301, and positioning protrusions 303 are located at the bottom of end plates 302. Specifically, positioning protrusions 303 are set at the bottom of end plates 302, and then end plates 302 are tightly connected to heat exchanger body 301, thereby achieving the setting of positioning protrusions 303 at the bottom of both circumferential ends of outdoor heat exchanger 30. This not only simplifies the structure of outdoor heat exchanger 30 and reduces the processing difficulty of positioning protrusions 303, but also increases the contact surface between positioning protrusions 303 and heat exchanger body 301, ensuring the structural stability and reliability of positioning protrusions 303, and preventing positioning protrusions 303 from breaking or deforming due to stress concentration.

[0054] Combination Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the positioning groove 103 is provided with a first guide portion 1031, and the positioning protrusion 303 is provided with a second guide portion 3031. The first guide portion 1031 and the second guide portion 3031 guide and cooperate with each other.

[0055] Specifically, when the positioning protrusion 303 is inserted into the positioning groove 103, the first guide portion 1031 and the second guide portion 3031 guide and cooperate. Through the guiding and restricting effects of the first guide portion 1031 and the second guide portion 3031, not only can the alignment accuracy between the positioning protrusion 303 and the positioning groove 103 be improved, and the installation accuracy of the outdoor heat exchanger 30 relative to the chassis 102 be improved, but the installation difficulty of the outdoor heat exchanger 30 relative to the chassis 102 can also be reduced, ensuring that the positioning protrusion 303 can smoothly slide into the positioning groove 103 and realize the positioning cooperation between the positioning protrusion 303 and the positioning groove 103. At the same time, the stress on the positioning protrusion 303 during the installation process can also be optimized, reducing the risk of the positioning protrusion 303 breaking or deforming.

[0056] When the positioning protrusion 303 is inserted into the positioning groove 103, even if the initial relative position of the positioning protrusion 303 and the positioning groove 103 is slightly deviated, under the guidance and cooperation of the first guide part 1031 and the second guide part 3031, the relative position of the positioning protrusion 303 and the positioning groove 103 will be automatically corrected under the action of the assembly force, thereby simplifying the installation process of the outdoor heat exchanger 30 and reducing the installation difficulty of the outdoor heat exchanger 30 relative to the chassis 102.

[0057] Combination Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the first guide portion 1031 is a first guide slope, and the second guide portion 3031 is a second guide slope. The first guide slope and the second guide slope are in a guiding fit.

[0058] Specifically, when the first guide slope contacts the second guide slope, the applied assembly force is decomposed into a vertical component and a horizontal component by the slope. If there is an initial positional deviation between the positioning protrusion 303 and the positioning groove 103, the horizontal component will push the positioning protrusion 303 to move laterally, thereby automatically correcting the position of the positioning protrusion 303 relative to the positioning groove 103.

[0059] Thus, when the positioning protrusion 303 extends into the positioning groove 103, the first guide slope and the second guide slope guide and cooperate. Through the guiding and restricting effects of the first guide slope and the second guide slope, not only can the alignment accuracy between the positioning protrusion 303 and the positioning groove 103 be improved, and the installation accuracy of the outdoor heat exchanger 30 relative to the chassis 102 be improved, but the installation difficulty of the outdoor heat exchanger 30 relative to the chassis 102 can also be reduced, ensuring that the positioning protrusion 303 can smoothly slide into the positioning groove 103 and achieve the positioning cooperation between the positioning protrusion 303 and the positioning groove 103. At the same time, the stress on the positioning protrusion 303 during the installation process can also be optimized, reducing the risk of the positioning protrusion 303 breaking or deforming.

[0060] In some embodiments of this utility model, the end plate 302 includes a first structural plate and a second structural plate. The first structural plate extends in the circumferential direction, and the second structural plate extends in the radial direction, that is, the first structural plate and the second structural plate are perpendicular to each other. In addition, the guide slopes at the bottom of the positioning protrusion 303 are respectively provided on the side of the bottom of the first structural plate away from the second structural plate, and on the side of the bottom of the second structural plate away from the first structural plate.

[0061] Moreover, viewed from top to bottom, the guide slope at the bottom of the first structural plate is inclined towards the side closer to the second structural plate, and the guide slope at the bottom of the second structural plate is inclined towards the side closer to the first structural plate.

[0062] The dimensions of the first structural plate and the second structural plate correspond to the structural dimensions of the positioning groove 103. The specific dimensions of the first structural plate, the second structural plate, and the positioning groove 103 can be adjusted according to the specific structure, specific requirements, and specific application environment of the outdoor unit 100 of the air conditioner.

[0063] Combination Figure 4 , Figure 6 and Figure 9 As shown, the chassis 102 is provided with an upwardly protruding connecting seat 104. The connecting seat 104 is located adjacent to the positioning groove 103 and has a first connecting hole 1041. The outdoor heat exchanger 30 is provided with a second connecting hole 3041. The first connecting hole 1041 and the second connecting hole 3041 correspond to each other and are connected by a first fastener 701.

[0064] Specifically, by providing an upwardly protruding connecting seat 104 on the chassis 102, and the connecting seat 104 being located at both circumferential ends of the outdoor heat exchanger 30, the upwardly protruding connecting seat 104 facilitates the alignment of the first connecting hole 1041 and the second connecting hole 3041, and facilitates the connection and installation between the connecting seat 104 and the outdoor heat exchanger 30.

[0065] Furthermore, a first connecting hole 1041 is provided on the connecting seat 104, and a corresponding second connecting hole 3041 is provided on the outdoor heat exchanger 30. The first connecting hole 1041 and the second connecting hole 3041 correspond in structure and position. The first fastener 701 is sequentially passed through the first connecting hole 1041 and the second connecting hole 3041, thereby connecting and fixing the outdoor heat exchanger 30 to the chassis 102.

[0066] In this way, the outdoor heat exchanger 30 can be effectively prevented from shifting or loosening in the vertical direction relative to the chassis 102. This not only further improves the stability and reliability of the connection between the outdoor heat exchanger 30 and the chassis 102, but also makes the bottom of the outdoor heat exchanger 30 fit more tightly with the chassis 102, further reducing the gap between the bottom of the outdoor heat exchanger 30 and the chassis 102 in the vertical direction. Moreover, the structure is simple and easy to implement.

[0067] In some embodiments of this utility model, the first connecting hole 1041 and the second connecting hole 3041 can be threaded holes, and the first fastener 701 can be a screw.

[0068] Combination Figure 4 , Figure 5 and Figure 6 As shown, the outdoor heat exchanger 30 includes: a heat exchange body 301 and an end plate 302.

[0069] The heat exchanger body 301 is arc-shaped and extends circumferentially along the casing 10. Specifically, the heat exchanger body 301 includes multiple U-shaped tubes. This arc shape and circumferential extension of the heat exchanger body 301 allows it to fit snugly against the inner wall of the casing 10, thereby improving not only the space utilization and structural compactness of the outdoor unit 100, but also optimizing the heat exchange area of ​​the outdoor heat exchanger 30 and enhancing its heat exchange effect. Furthermore, the arc-shaped structure enhances the structural strength and stability of the heat exchanger body 301, preventing stress concentration issues caused by sharp corners.

[0070] Furthermore, the end plate 302 covers both circumferential ends of the heat exchange body 301, and the end plate 302 is provided with a connecting piece 304. The connecting piece 304 fits into the connecting seat 104, and the second connecting hole 3041 is opened on the connecting piece 304.

[0071] Specifically, a connecting piece 304 is provided on the end plate 302 so that the connecting piece 304 fits against the connecting seat 104, and the second connecting hole 3041 is opened on the connecting piece 304. This not only prevents damage to the structure of the heat exchange body 301 and the end plate 302 when the second connecting hole 3041 is opened, but also reduces the complexity of opening the second connecting hole 3041, which is beneficial to reducing the processing cost of the outdoor unit 100 of the air conditioner. It also simplifies the connection between the connecting seat 104 and the end plate 302, and prevents interference between the connection and cooperation of the second connecting hole 3041 and the first connecting hole 1041 and the positioning cooperation of the positioning protrusion 303 and the positioning groove 103. This can improve the structural reliability and structural rationality of the outdoor unit 100 of the air conditioner.

[0072] In some embodiments of this utility model, the heat exchange body 301 includes multiple U-shaped tubes, which are spaced apart in the vertical direction and are interconnected with each other.

[0073] Combination Figure 1 and Figure 10 As shown, the main housing 101 is provided with a third connection hole 1013, and the outdoor heat exchanger 30 is provided with a fourth connection hole 305. The third connection hole 1013 and the fourth connection hole 305 correspond to each other and are connected by a second fastener 702.

[0074] Specifically, a third connecting hole 1013 is provided on the main housing 101, and a fourth connecting hole 305 is provided on the outdoor heat exchanger 30. The third connecting hole 1013 and the fourth connecting hole 305 correspond in structure and position. The second fastener 702 is sequentially passed through the third connecting hole and the fourth connecting hole 305, thereby connecting and fixing the outdoor heat exchanger 30 to the main housing 101. This not only makes the connection and fixing between the outdoor heat exchanger 30 and the main housing 101 simple, direct, stable and reliable, but also facilitates the installation and disassembly of the outdoor heat exchanger 30 and the main housing 101, and facilitates the subsequent maintenance and replacement of the outdoor heat exchanger 30 and the main housing 101.

[0075] In some embodiments of this utility model, the fourth connection hole 305 is provided on the protruding structure on the end plate 302 of the outdoor heat exchanger 30.

[0076] In some embodiments of this utility model, the third connecting hole 1013 and the fourth connecting hole 305 can be threaded holes, and the second fastener 702 can be a screw.

[0077] Combination Figure 1 and Figure 10 As shown, the main housing 101 includes a housing portion and a front cover portion 1011. The front side of the housing portion is at least partially open, and the front cover portion 1011 covers the open side of the housing portion. A third connecting hole 1013 is provided in the front cover portion 1011.

[0078] Specifically, the front side of the housing is at least partially open, which facilitates the installation and removal of internal components of the outdoor unit 100 of the air conditioner, and facilitates the inspection and maintenance of the internal components of the outdoor unit 100 of the air conditioner.

[0079] Furthermore, the front cover 1011 is provided on the open side of the housing to create a relatively enclosed environment for the outdoor unit 100 of the air conditioner. This not only facilitates the formation of the internal air duct of the outdoor unit 100, but also prevents external foreign objects from entering the interior of the outdoor unit 100 through the open side, and isolates the internal components of the outdoor unit 100, preventing users or maintenance personnel from accidentally touching the internal components of the outdoor unit 100.

[0080] Furthermore, the housing portion and the front cover portion 1011 are in contact and securely connected. The third connecting hole 1013 is provided in the front cover portion 1011. Fasteners are passed through the third connecting hole 1013 and the fourth connecting hole 305 to achieve the connection and fixation between the front cover portion 1011 and the outdoor heat exchanger 30. In turn, the connection and fixation between the main housing 101 and the outdoor heat exchanger 30 is achieved through the front cover portion 1011. This not only ensures the secure connection between the main housing 101 and the outdoor heat exchanger 30, but also ensures the structural rationality and structural reliability of the outdoor unit 100 of the air conditioner.

[0081] In addition, the main housing 101 also includes a mesh cover, which has a filtering function. The air inlet 50 is on the main housing 101. The air flowing through the air inlet 50 is filtered by the mesh cover, which can improve the cleanliness of the air flowing through the air inlet 50, thereby improving the cleanliness of the internal environment of the outdoor unit air conditioner and extending the service life of the outdoor unit 100.

[0082] It should be noted that the installation of the mesh cover involves pressing its circumferential edge onto the surrounding structure, such as the chassis 102, top cover, front cover 1011, and connecting plate on the main housing 101. Any suitable structure will suffice, as this facilitates cleaning of the mesh cover. In some specific embodiments of this invention, the mesh cover can be pressed and connected to the front cover 1011 in the circumferential direction.
