[0028] To provide a clearer understanding of the technical features, objectives, and effects of this application, the specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0030] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "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 used 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 specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," "located in," and "located in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or a chemical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] like Figures 5 to 9 As shown, this application constructs an air guiding structure 10, which can be combined with a fan assembly 40, a heat exchange assembly 50, etc. to form an indoor unit, circulate and exchange heat on indoor air, and achieve the cooling or heating effect on the indoor environment.

[0033] The air guide structure 10 defines an air guide port 100, which is connected to the air outlet of the fan assembly 40 and is used to guide the airflow generated by the fan assembly 40 to the heat exchange assembly 50.

[0034] Specifically, the air guide 100 is generally rectangular in shape and is defined by four air guide walls connected sequentially in four directions of extension. These are now defined as the first air guide wall 11, the second air guide wall 12, the third air guide wall 13, and the fourth air guide wall 14. The first air guide wall 11 and the second air guide wall 12 are arranged opposite each other, and the third air guide wall 13 and the fourth air guide wall 14 are arranged opposite each other.

[0035] See also Figure 4 The operating angle is defined as the angle at which the indoor unit is installed on the top wall of the house for normal operation. The angle at which the air guide structure 10 is located within this reference angle is then defined as its operating angle. When the air guide structure 10 is at its operating angle, the first air guide wall 11 and the second air guide wall 12 extend horizontally along their lengths and are parallel to the drive shaft 43 of the fan assembly 40. The first air guide wall 11 is located at the bottom of the air outlet 100, and the second air guide wall 12 is located at the top of the air outlet 100. The third air guide wall 13 and the fourth air guide wall 14 extend vertically along their lengths and are perpendicular to the drive shaft 43 of the fan assembly 40.

[0036] like Figure 7 and Figure 9 As shown, along the airflow direction Q, the air guide structure 10 includes an air inlet side 101 and an air outlet side 102 arranged opposite to each other. Then, the cross-sectional dimension of the air guide 100 corresponding to the air inlet side 101 is smaller than the cross-sectional dimension corresponding to the air outlet side 102.

[0037] By setting the diameter of the air outlet 102 of the air guide 100 to be larger than the diameter of the air inlet 101, the air guide 100 can be roughly flared, which can optimize the airflow direction Q and achieve higher heat exchange under the premise of the same circulating air volume. By setting the air guide structure 10 to a rectangular shape, the production and manufacturing of the air guide structure 10 can be facilitated.

[0038] In other embodiments, the air vent 100 may also be in various other shapes such as circular, semi-circular, elliptical, semi-elliptical, polygonal, or irregular.

[0039] It should be understood that when the air guide 100 is circular or has an arc-shaped opening wall, the first air guide wall 11, the second air guide wall 12, the third air guide wall 13, and the fourth air guide wall 14 can also be understood as four parts of the opening wall of the circular air guide 100, which are smoothly connected to form a circular or elliptical air guide 100 with an arc-shaped opening wall.

[0040] Of course, when the air guide 100 is semi-circular, circular, quadrilateral, triangular, or other shapes, it can also be formed by two air guide walls joined together. When the air guide 100 is triangular or other shapes, it can also be formed by three air guide walls. When the air guide 100 is pentagonal or other polygonal, it can also be formed by five or more air guide walls.

[0041] It should be understood that the first air guide wall 11, the second air guide wall 12, the third air guide wall 13 and the fourth air guide wall 14 can be assembled together detachably or non-detachably through various connection methods such as integral molding, welding, bolt connection, snap connection, and plug-in.

[0042] It should be understood that the air guide structure 10 can be integrally formed with the volute 411 of the fan assembly 40 to form a single structure. Alternatively, the air guide structure 10 can also be detachably or non-detachably assembled with the fan assembly 40 through bolted connections, threaded connections, welding, snap-fit ​​connections, interference fits, plug-in connections, etc. No specific limitations are made here.

[0043] like Figure 5 and Figure 6 As shown, in some embodiments, the air guide structure 10 may also include other structures such as mounting members 15 and connecting members 16, which can be detachably or non-detachably connected to at least one structure among the first air guide wall 11, the second air guide wall 12, the third air guide wall 13 and the fourth air guide wall 14, for detachable or non-detachable connection with other components in the indoor unit such as the fan assembly 40.

[0044] Specifically, the mounting component 15 and the connector 16 can adopt various plate-shaped, block-shaped, strip-shaped structures such as stiffeners, buckles, slots, and lugs, without any specific limitations.

[0045] like Figure 7 As shown, from the air inlet side 101 to the air outlet side 102 of the air guide 100, the first air guide wall 11 is inclined away from the second air guide wall 12. Its inclination angle is defined as a first inclination angle α, which is greater than or equal to 25° and less than or equal to 45°.

[0046] For example, the first tilt angle α can be 26°, 28°, 30°, 32°, 34°, 36°, 38°, 40°, 42°, 44°, or any other value within the region.

[0047] It should be understood that from the air inlet side 101 to the air outlet side 102 of the air guide 100, the first air guide wall 11 is inclined away from the second air guide wall 12. This can be understood as the horizontal position of the side of the first air guide wall 11 corresponding to the air inlet side 101 being higher than the horizontal position of the side of the first air guide wall 11 corresponding to the air outlet side 102 when the air guide structure 10 is at the working angle.

[0048] The first tilt angle α can be understood as the angle between the first air guide wall 11 and the horizontal plane when the air guide structure 10 is located at the working angle.

[0049] Table 1 shows a comparison of heat exchange data generated by multiple sets of tests, with indoor units having the air guide structure 10 constructed in this application and those without the air guide structure 10 constructed in this application, under the premise of setting the same circulating air volume as much as possible.

[0050] The first tilt angle α of the first guide wall 11 selected in the test of the wind-guiding structure 10 in Table 1 is 40°.

[0051] As shown in Table 1, under the premise of the same circulating air volume, the indoor unit with the air guiding structure 10 constructed in this application has a significantly higher heat exchange capacity than related technologies. That is, the air guiding structure 10 constructed in this application can improve the heat exchange capacity of the indoor unit during operation.

[0052] Table 1 Comparison of Heat Exchange Test Data

[0053]

[0054] It should be understood that, in order to ensure the accuracy of the test results, the only difference between "indoor unit with the air guide structure 10 constructed in this application" and "related technology" is whether or not the air guide structure 10 constructed in this application is present.

[0055] See also Figure 8 In some embodiments, from the air inlet side 101 to the air outlet side 102 of the air guide 100, the second air guide wall 12 is inclined toward the first air guide wall 11. Its inclination angle is defined as a second inclination angle β, which is less than the first inclination angle α of the first air guide wall 11.

[0056] That is, when the air guide structure 10 is at the working angle, from the air inlet side 101 to the air outlet side 102 of the air guide 100, the first air guide wall 11 and the second air guide wall 12 are both inclined downwards, and the second downward inclination angle β of the second air guide wall 12 is greater than the first inclination angle α of the first air guide wall 11.

[0057] It should be understood that from the air inlet side 101 to the air outlet side 102 of the air guide 100, the second air guide wall 12 is inclined towards the first air guide wall 11. This can be understood as the horizontal position of the side of the second air guide wall 12 corresponding to the air inlet side 101 being higher than the horizontal position of the side of the second air guide wall 12 corresponding to the air outlet side 102 when the air guide structure 10 is at the working angle.

[0058] The second tilt angle β can be understood as the angle between the second air guide wall 12 and the horizontal plane when the air guide structure 10 is located at the operating angle.

[0059] This configuration can further improve the efficiency of airflow to the heat exchange component 50, thereby further increasing the heat exchange capacity.

[0060] Furthermore, the second tilt angle β of the second wind guide wall 12 is greater than or equal to 1° and less than or equal to 5°. For example, the second tilt angle β can be 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, or any other value within this region.

[0061] It should be understood that the second tilt angle β of the second guide wall 12 of the air guide structure 10 used in the experiment in Table 1 above is 2°.

[0062] like Figure 5 and Figure 6 As shown, in some embodiments, the two ends of the third air guide wall 13 along its length are respectively connected to one end of the first air guide wall 11 along its length and one end of the second air guide wall 12 along its length. The two ends of the fourth air guide wall 14 along its length are respectively connected to the other end of the first air guide wall 11 along its length and the other end of the second air guide wall 12 along its length.

[0063] Specifically, such as Figure 9 As shown, from the air inlet side 101 to the air outlet side 102 of the air guide 100, the third air guide wall 13 is inclined away from the fourth air guide wall 14. The inclination angle of the fourth air guide wall 14 is now defined as the third inclination angle γ.

[0064] Furthermore, the third tilt angle γ is greater than or equal to 10° and less than or equal to 20°. For example, the third tilt angle γ can be 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, or any other value within this region.

[0065] It should be understood that the third tilt angle γ can be understood as the angle between the third air guide wall 13 and the vertical plane perpendicular to the first air guide wall 11 and the second air guide wall 12 when the air guide structure 10 is located at the working angle.

[0066] It should be understood that the third tilt angle γ of the third wind guide wall 13 of the wind guide structure 10 used in the experiment in Table 1 above is 15°.

[0067] Continue reading Figure 9 In some embodiments, from the air inlet side 101 to the air outlet side 102 of the air guide 100, the fourth air guide wall 14 is inclined away from the third air guide wall 13. The inclination angle of the fourth air guide wall 14 is now defined as the fourth inclination angle θ.

[0068] Specifically, the fourth tilt angle θ is greater than or equal to 10° and less than or equal to 20°. For example, the fourth tilt angle θ can be 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, or any other value within this region.

[0069] It should be understood that the fourth tilt angle θ can be understood as the angle between the fourth air guide wall 14 and the vertical plane perpendicular to the first air guide wall 11 and the second air guide wall 12 when the air guide structure 10 is located at the working angle.

[0070] It should be understood that the fourth tilt angle θ of the fourth wind guide wall 14 of the wind guide structure 10 used in the experiment in Table 1 above is equal to the third tilt angle γ of the third wind guide wall 13, both being 15°.

[0071] By setting the third guide wall 13 and the fourth guide wall 14 to have the same tilt angle, the symmetry and uniformity of the airflow direction can be facilitated, thereby improving the uniformity of the airflow when it flows through the heat exchange component 50, which is conducive to further improving the heat exchange efficiency.

[0072] Of course, in some other embodiments, the specific value of the third tilt angle γ selected by the third air guide wall 13 may be different from the specific value of the fourth tilt angle θ selected by the fourth air guide wall 14. When the specific value of the third tilt angle γ selected by the third air guide wall 13 may be the same as the specific value of the fourth tilt angle θ selected by the fourth air guide wall 14, the values ​​of both may also be any other values ​​within the aforementioned region.

[0073] like Figure 7 and Figure 9 As shown, in some embodiments, the thickness H of the air guide structure 10 is greater than or equal to 15 mm and less than or equal to 25 mm. For example, the thickness H can be 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, or any other value within this region.

[0074] It should be understood that the thickness H of the air guide structure 10 can be understood as the distance between the air guide structure 10 from the air inlet side 101 to the air outlet side 102. This thickness H can be the same as the depth of the air guide 100 or greater than the depth of the air guide 100, and no specific limitation is made here.

[0075] It should be understood that the thickness H of the air guide structure 10 used in the experiment in Table 1 above is 20.5 mm.

[0076] like Figures 1 to 4 As shown, this application also constructs an indoor unit, which includes at least one air guide structure 10 as in any of the foregoing embodiments. This indoor unit can cooperate with an outdoor unit to form a heat exchange circulation system, achieving cooling or heating effects on the indoor environment.

[0077] The indoor unit also includes a fan assembly 40 and at least one heat exchange assembly 50. The fan assembly 40 generates airflow to facilitate heat exchange. The heat exchange assembly 50 exchanges heat with the flowing gas to achieve a cooling or heating effect. An air guide structure 10 is disposed between the heat exchange assembly 50 and the fan assembly 40 to guide the airflow generated by the fan assembly 40 to the heat exchange assembly 50 for heat exchange.

[0078] Furthermore, the indoor unit may also include a housing 20 and a partition 30. The housing 20 is hollow inside, used to house the air guiding structure 10, the partition 30, the fan assembly 40, and the heat exchange assembly 50. The partition 30 is disposed within the housing 20, dividing the space within the housing 20 into a fan chamber 21 and a heat exchange chamber 22. The fan assembly 40 is disposed within the fan chamber 21, and the heat exchange assembly 50 is disposed within the heat exchange chamber 22.

[0079] like Figure 1 and Figure 2 As shown, the housing 20 can be a longitudinally elongated rectangular shape with a hollow interior. The partition 30 is also longitudinally elongated rectangular, extending along the length and thickness of the housing 20, so as to divide the space inside the housing 20 into two adjacent and longitudinally elongated fan chambers 21 and heat exchange chambers 22.

[0080] Of course, the shell 20 can also be configured as a cylindrical, elliptical, semi-circular, polygonal, irregular, polygonal, or other irregular shapes. The shape of the partition 30 can be adjusted accordingly to accommodate changes in the shape of the shell 20. No specific limitations are imposed here.

[0081] The housing 20 may also define an air inlet window 23 and an air outlet window 24. The air inlet window 23 connects the fan chamber 21 to the outside, so that the fan assembly 40 can draw in outside air through the air inlet window 23. The air outlet window 24 connects the heat exchange chamber 22 to the outside, so that the airflow after passing through the heat exchange assembly 50 can flow out of the housing 20 through the air outlet window 24.

[0082] Specifically, the air inlet window 23 is located on the side of the fan cavity 21 away from the partition 30, and the air outlet window 24 is located on the side of the heat exchange cavity 22 away from the partition 30. That is, the air inlet window 23 and the air outlet window 24 are located on opposite sides of the housing 20. This arrangement facilitates the guidance of airflow, reduces airflow deflection within the housing 20, and minimizes the impact on the volume of circulating air and the heat exchange capacity.

[0083] In some other embodiments, the air inlet window 23 and the air outlet window 24 may also be located on any other side of the housing 20. By improving the layout and structural arrangement of the partition 30, fan assembly 40, heat exchange assembly 50 and air guide structure 10 within the housing 20, the air duct can be redirected.

[0084] In some embodiments, the housing 20 may include a main body 201 and at least one mounting fitting 202. The main body 201 defines a fan chamber 21, a heat exchange chamber 22, an air inlet window 23, and an air outlet window 24. The mounting fitting 202 is disposed on the main body 201 for mounting the indoor unit to a wall in the room.

[0085] Specifically, four of these fittings 202 can be used, all located on the same side of the casing 20 in the thickness direction, and distributed at the four corners of the main body 201 along the length and width directions of the casing 20. This arrangement facilitates the mounting of the indoor unit onto the top wall of the house, allowing the indoor unit to be positioned at a reference angle for normal operation. At this angle, the air guide structure 10 is in its operating angle.

[0086] It should be understood that the assembly 202 can adopt various connection structures such as anchors, hangers, expansion bolts, and stiffening plates, and no specific limitation is made here.

[0087] In some other embodiments, the number of the assembly 202 may also be one, two, three, five, etc.

[0088] It should be understood that the main body 201 can be made from a single structure in an integral molding manner, or it can be formed by multiple structures through various connection methods such as bolt connection, snap connection, thread connection, welding, etc., and can be detachably or non-detachably assembled. No specific limitation is made here.

[0089] like Figure 3As shown, in some embodiments, the partition 30 defines at least one connection port 31 that connects the fan chamber 21 to the heat exchange chamber 22. The number of connection ports 31 can be adapted to the number of air guide structures 10 so that the air guide structures 10 can guide the airflow output by the fan assembly 40 from the connection port 31 to the heat exchange assembly 50 located in the heat exchange chamber 22.

[0090] It should be understood that the partition 30 can be detachably or non-detachably installed in the housing 20 through various methods such as bolt connection, snap connection, threaded connection, welding, integral molding, etc., without specific limitations.

[0091] like Figure 3 and Figure 4 As shown, in some embodiments, the heat exchange assembly 50 may include a water receiving tray 52 and at least one heat exchanger 51. Both the water receiving tray 52 and the heat exchanger 51 are disposed within the heat exchange chamber 22, with the heat exchanger 51 used to exchange heat with the flowing air. The water receiving tray 52 is disposed at the bottom end of the heat exchanger 51 and is used to receive condensate.

[0092] exist Figure 1 and Figure 3 In the illustrated embodiment, there is one heat exchanger 51, which is arranged in the shape of a longitudinally elongated rectangular plate, extending along the length of the housing 20. See also... Figure 4 The heat exchanger 51 is inclined in the width and thickness directions of the shell 20, and has an angle with the axis of the shell 20 in both the width and thickness directions.

[0093] By setting the heat exchanger 51 at an angle, boundary layer separation can be broken, dead zones in the airflow can be reduced, and heat exchange efficiency can be improved. At the same time, this setting also allows condensate to flow smoothly along the plate surface to the water collection tray 52 under the action of gravity, avoiding water accumulation in the heat exchanger 51 and improving the condensate drainage speed.

[0094] By setting the number of heat exchangers 51 to one and setting it to extend along the length direction of the shell 20, it can be coordinated with the outward expansion and tilting angle of the third air guide wall 13 and the fourth air guide wall 14 of the air guide structure 10, so that the airflow diffuses along the length direction of the heat exchanger 51 and passes through the heat exchanger 51, thereby increasing the heat exchange area and further increasing the heat exchange capacity.

[0095] It should be understood that when there are multiple air guide structures 10 and multiple fans 41 in the fan assembly 40, the number of heat exchangers 51 can also be set to multiple. Each heat exchanger 51 can correspond one-to-one with an air guide structure 10 and a fan 41, or each heat exchanger 51 can correspond to at least two air guide structures 10 and fans 41, etc.

[0096] In some embodiments, the inclined lower side of the heat exchanger 51 may extend into the water receiving tray 52 to facilitate the collection of condensate and prevent leakage.

[0097] Specifically, taking the operating angle of the indoor unit after it is installed on the top wall of the house as a reference angle, the setting position of the heat exchange component 50 will be further explained. Figure 4 As shown, at this operating angle, the water receiving tray 52 is located on the side of the heat exchanger 51 away from the assembly 202. Along the width direction of the shell 20, the horizontal position of the side of the heat exchanger 51 away from the partition 30 is higher than the horizontal position of the side closer to the partition 30.

[0098] This angle, combined with the downward tilt of the first air guide wall 11 and the second air guide wall 12 of the air guide structure 10, allows the downward tilting airflow from the air guide port 100 to flow smoothly through the heat exchanger 51, further improving the heat exchange efficiency of the airflow and reducing the dead zone of the airflow.

[0099] Of course, the setting angle of the heat exchanger 51 can be flexibly adjusted according to the setting angle and air outlet direction of the fan assembly 40.

[0100] For example, when the air guide structure 10 is installed inside the housing 20, the first air guide wall 11 is located on the top side of the second air guide wall 12, and both the air inlet side 101 and the air outlet side 102 of the air guide port 100 are inclined upwards. In this embodiment, the heat exchanger 51 can be correspondingly configured such that the horizontal position on the side away from the partition 30 is lower than the horizontal position on the side closer to the partition 30. There are many potential embodiments, which will not be elaborated here.

[0101] It should be understood that the heat exchanger 51 can be implemented using existing technologies such as finned heat exchangers and plate heat exchangers, which will not be elaborated on here.

[0102] like Figure 3 and Figure 4 As shown, in some embodiments, the fan assembly 40 includes a motor 42, a drive shaft 43, and at least one fan 41. The drive shaft 43 is connected to the output shaft of the motor 42 and is rotatably mounted under the drive of the output shaft of the motor 42. The fan 41 includes a volute 411 and a fan wheel 412. The volute 411 is fixed inside the fan cavity 21, the drive shaft 43 passes through the volute 411, and the fan wheel 412 is disposed inside the volute 411 and mounted on the drive shaft 43, so as to be driven to rotate by the drive shaft 43 to realize the generation and transmission of airflow.

[0103] Specifically, the volute 411 has an air outlet, and the air guide structure 10 can be set at the air outlet of the volute 411. The airflow generated by the rotation of the impeller 412 passes through the air outlet of the volute 411 and the air guide structure 10 and is guided to the heat exchange assembly 50.

[0104] Furthermore, the number of these fans 41 can be multiple, for example in... Figure 2 and Figure 3 In the illustrated embodiment, there are three fans. The three fans 41 are coaxially arranged so that the drive shaft 43 passes through them sequentially. Furthermore, the impellers 412 of the three fans 41 are respectively mounted on the drive shaft 43 so as to rotate synchronously under the drive of the motor 42. Correspondingly, the air guiding structure 10 can be configured in multiple ways corresponding to the volute 411 of the fans 41.

[0105] In some other embodiments, when there are multiple fans 41, the fan assembly 40 may also include multiple motors 42 and multiple drive shafts 43, so that each fan 41 has a corresponding motor 42 and drive shaft 43 for individual driving.

[0106] It should be understood that the motor 42 and the fan 41 can be implemented using existing technologies such as cross-flow fans, axial flow fans, and mixed flow fans, and no specific limitations are made here.

[0107] In some embodiments, the connection port 31, the air guide port 100, and the air outlet of the volute 411 are all rectangular.

[0108] In other embodiments, the air outlets of the connection port 31, air guide port 100, and volute 411 can also be configured as circular, polygonal, elliptical, irregular, or other shapes. The shapes of the three can be identical, or at least one outlet can have a different shape than the remaining outlets.

[0109] like Figure 4 As shown, in some embodiments, the air guide structure 10 may be located inside the fan cavity 21, between the baffle 30 and the air outlet of the volute 411, and guides the airflow to the heat exchanger 51 through the connection port 31. Specifically, the air guide structure 10 may be detachably installed from the volute 411.

[0110] It is important to understand that in related technologies, the air guide structure 10 and the volute 411 are generally integrally molded. This configuration requires a mold-making process for production, resulting in higher production costs and lower efficiency. Furthermore, for indoor units with different air outlet angle requirements, each unit needs to be molded individually, making modular production difficult and reducing application flexibility, further increasing production costs.

[0111] This application allows the air guide structure 10 and the fan assembly 40 to be detachably connected, enabling them to be manufactured separately. During production, no mold opening is required; the components can be obtained through CNC machining, reducing production costs and improving production efficiency.

[0112] At the same time, this configuration also improves the flexibility of the fan 41 application. For indoor units with different air outlet angle requirements, only the structure or setting angle of the air guide structure 10 needs to be adjusted or replaced, without adjusting or replacing the entire fan 411. This further facilitates modular manufacturing, further reduces costs, and improves efficiency.

[0113] It should be understood that in related technologies, in order to ensure the production and assembly of the integrally formed air guide structure 10 and the volute 411, the thickness of the air guide structure 10 is generally relatively thick, occupying the space inside the housing 20.

[0114] By detachably setting the air guide structure 10 and the volute 411, this application allows the thickness of the air guide structure 10 to be controlled between 15mm and 25mm, effectively reducing the thickness of the air guide structure 10 and thus improving the space utilization of the housing 20, which facilitates the miniaturization of the indoor unit.

[0115] It should be understood that the detachable connection between the air guide structure 10 and the volute 411 can be achieved through various connection methods such as bolt connection, threaded connection, snap-fit ​​connection, plug-in connection, and slot connection, without being specifically limited here.

[0116] It should be understood that the air guide structure 10 and the partition plate 30 can be connected and assembled detachably or non-detachably through various connection methods such as welding, bolt connection, plug-in connection, snap-fit ​​connection, threaded connection, and slot connection, without specific limitations.

[0117] Of course, in some other embodiments, the air guide structure 10 can also be non-detachably connected and assembled with the volute 411 by welding, integral molding or other means.

[0118] In some other embodiments, the air guide structure 10 may also be installed inside the connection port 31, partly located inside the fan cavity 21 for detachable connection with the volute 411, and partly located inside the heat exchange cavity 22 for guiding the airflow to the heat exchanger 51.

[0119] In some other embodiments, the air guide structure 10 may also be disposed within the heat exchange chamber 22, located between the partition 30 and the heat exchanger 51, and detachably connected to the partition 30. In this embodiment, the air outlet end of the volute 411 may be connected to the side of the partition 30 facing the fan chamber 21, so that its air outlet is connected to the connection port 31, and then connected to the air guide port 100. Alternatively, the air outlet end of the volute 411 may also pass through the connection port 31, partially extending into the heat exchange chamber 22, so as to be detachably connected to the air inlet side 101 of the air guide structure 10, so that the air outlet of the volute 411 is directly connected to the air guide port 100.

[0120] It is understood that the above embodiments only illustrate some implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that those skilled in the art can freely combine the above embodiments or technical features without departing from the concept of this application, and can also make several modifications and improvements, all of which fall within the protection scope of this application. That is, the embodiments described "in some embodiments" can be freely combined with any of the preceding and following embodiments. Therefore, all equivalent transformations and modifications made within the scope of the claims of this application should be covered by the claims of this application.
