[0060] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0061] It should be understood that the terms used herein are only for the purpose of describing specific example embodiments and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "include", "comprise", "contain", and "have" are inclusive, and therefore specify the existence of stated features, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not interpreted as necessarily requiring them to be performed in the specific order described or illustrated, unless the execution order is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0062] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0063] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is turned over, then the elements described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0064] In the outdoor unit of the HVAC equipment, the air guide ring above the heat exchange cavity is used to accommodate the fan blades of the outdoor unit and can increase the flow rate of the airflow in the heat exchange cavity. The bottom of the air guide ring is connected to the heat exchange cavity. The structural strength of the bottom of the air guide ring directly affects the connection stability between the air guide ring and the heat exchange cavity. If the structural strength of the connection at the bottom of the air guide ring is not good, it is easy to cause the air guide ring to shake or move unnecessarily during operation, which will also directly affect the operating stability and reliability of the outdoor unit of the HVAC equipment, such as causing abnormal noise or shaking of the outdoor unit body.

[0065] In view of this, the utility model provides an outdoor unit of a HVAC equipment, aiming to solve the above problems by improving the structure of the connection between the air guide ring and the heat exchange chamber and enhancing the structural strength of the bottom connection part of the air guide ring.

[0066] Embodiment 1

[0067] Combined with Figure 1 and attached Figure 2 As shown in , the first aspect of this embodiment provides a HVAC equipment outdoor unit 100, which includes a heat exchanger 10 and an air guide ring 20. The shape of the heat exchanger 10 can be a structure with a cross-section approximately rectangular as shown in the figure, or a structure with a cross-section approximately circular, and the cross-section of the heat exchanger 10 can be a non-completely closed structure to form a gap to install an electrical control box (not shown in the figure). The specific structural forms of the heat exchanger are not listed one by one in this embodiment.

[0068] The heat exchanger 10 of this embodiment has a heat exchange chamber 11, or the inner wall of the heat exchanger 10 forms the heat exchange chamber 11. The specific structure of the heat exchange chamber 11 can be referred to in the following attached Figure 5 In the structure, the heat exchanger 10 is open at the top and bottom and has a notch 13 at one diagonal position.

[0069] On the outside of the heat exchanger 10 of the present embodiment, the HVAC equipment outdoor unit 100 is provided with an outer shell 30 for protecting its own internal structure. The outer shell 30 is provided with an air inlet grille 31. The airflow flowing into the outer shell 30 from the air inlet grille 31 can enter the lower part of the air guide ring 20 of the present embodiment and flow out from the top of the air guide ring 20, thereby completing the heat exchange inside the HVAC equipment outdoor unit 100.

[0070] The air guide ring 20 of this embodiment is located above the heat exchanger 10 and is connected to the heat exchange cavity 11. Specifically, the air guide ring 20 may be provided with an air inlet 21, an air guide channel 22 and an air outlet 23 that are connected in sequence, the radial dimensions of the air inlet 21 and the air outlet 23 may be larger than the radial dimensions of the air guide channel 22, the air guide channel 22 is used to accommodate the fan blades 40 of the HVAC equipment outdoor unit 100, and the air guide ring 20 is provided with a connecting portion 24 on the outer wall at the air inlet 21, and the connecting portion 24 is used to connect the heat exchanger 10 of the HVAC equipment outdoor unit 100.

[0071] The connection parts 24 of this embodiment are arranged at intervals along the bottom circumference of the air guide ring 20, and extend radially outward along the air guide ring 20. The connection parts 24 are connected to the top of the heat exchanger 10, and the connection method can be any form such as snap-on, bolt connection, plug-in and welding.

[0072] The connection part 24 of this embodiment can be a plate-like structure or a block-like structure. The multiple connection parts 24 can not only improve the stability of the air guide ring 20 installed on the heat exchange chamber 11, but also do not need a circumferentially surrounding connection structure like some existing ones. The multiple connection parts 24 are arranged at intervals along the circumference to save materials, thereby reducing a certain production cost.

[0073] In order to improve the structural strength of the connection part 24, the connection part 24 of this embodiment is provided with a first reinforcement structure 25. The "reinforcement" in the first reinforcement structure 25 means that the structural strength of the connection part 24 can be enhanced by the structure, and the structural strength can be reflected in the parameters such as bending resistance and tensile and compressive resistance of the connection part 24. By connecting the connection part 24 having the first reinforcement structure 25 with the heat exchanger 10, the stability of the air guide ring 20 after installation can be improved, the possibility of deformation of the connection part 24 can be reduced, and the possibility of deformation and shaking of the air guide ring 20 can be reduced, thereby improving the operating stability and reliability of the entire outdoor unit.

[0074] It should be noted that in this embodiment, Figure 2 The air guide ring 20 in the figure only shows a partial structure of its bottom surface. For the specific structure of the air guide ring 20, please refer to the attached figure of this embodiment. Figure 3 and attached Figure 4 , attached Figure 3 and attached Figure 4 The air guide ring 20 and Figure 2The air guide ring 20 in the embodiment is different only in the structural form of the first reinforcement structure 25 of the connecting portion 24. Figure 2 The structure of the air guide ring 20 not shown in the figure can be referred to in the attached Figure 3 and attached Figure 4 The air guide ring 20 in the middle.

[0075] In some examples, the connection portion 24 of this embodiment is optionally provided with a first surface 241 facing the heat exchanger 10 and a second surface 242 away from the heat exchanger 10, and the second surface 242 of this embodiment is provided with a first reinforcement structure 25. Figure 2 It is not shown in the figure, but please refer to the attached Figure 3 and attached Figure 4 The second surface 242 in the embodiment is attached with respect to the first surface 241 of the present embodiment. Figure 3 and attached Figure 4 It is not shown in the figure, but please refer to the attached Figure 2 The first surface 241 in.

[0076] In this embodiment, a first reinforcement structure 25 is provided on the second surface 242, so that the first reinforcement structure 25 is located on the side of the mounting portion away from the heat exchange cavity 11, to prevent the first reinforcement structure 25 from interfering with the side wall of the heat exchange cavity 11 and affecting the connection between the air guide ring 20 and the heat exchange cavity 11. Of course, the first reinforcement structure 25 of this embodiment can also be provided on the first surface 241 facing the heat exchange cavity 11, but the first reinforcement structure 25 needs to be away from the top of the heat exchanger 10.

[0077] Combined with the attachment again Figure 2 As shown in , in some examples, optionally, this embodiment is provided with a groove 251 recessed toward the second surface 242 on the first surface 241, and the bottom wall of the groove 251 protrudes from the second surface 242 (not shown in the figure) to form the first reinforcement structure 25 of this embodiment.

[0078] In this embodiment, the first reinforcement structure 25 in the form of reinforcement ribs is formed by the bottom wall of the groove 251 protruding toward the second surface 242. The groove 251 can be integrally formed when the connecting portion 24 is formed, and there is no need to form the first reinforcement structure 25 by adding materials. In addition, this structural form is more suitable for the air guide ring 20 made of sheet metal material, because the hardness of the sheet metal material is relatively high, so it is not conducive to directly forming the first reinforcement structure 25 by injection molding. The groove 251 form only needs to be pressed to realize the formation of the groove 251, which is conducive to processing and can improve a certain processing efficiency.

[0079] In some examples, optionally, in this embodiment, the groove 251 includes a first strip groove 2511 and a second strip groove 2512 , and the first strip groove 2511 and the second strip groove 2512 are connected and intersect in the length direction.

[0080] In this embodiment, the first strip groove 2511 and the second strip groove 2512 intersect in the length direction and have various structural forms. For example, one end of the first strip groove 2511 intersects with one end of the second strip groove 2512 to form an L-shaped or V-shaped groove (this embodiment is not shown in the figure), or Figure 2 As shown in the figure, the middle of the first strip groove 2511 intersects with the middle of the second strip groove 2512, and the two form a cross groove, so that the second surface 242 forms a cross-shaped reinforcement rib. The cross-shaped reinforcement rib has a better structural reinforcement effect than the straight reinforcement rib.

[0081] Furthermore, the length direction of the first strip groove 2511 of this embodiment can be designed to be arranged along the radial direction of the air guide ring 20, and the length direction of the second strip groove 2512 can be designed to be arranged along the circumferential direction of the air guide ring 20, so that the reinforcement ribs formed by the first strip groove 2511 on the second surface 242 can offset the radial external force of the connecting part 24, and the reinforcement ribs formed by the second strip groove 2512 on the second surface 242 can offset the circumferential external force, thereby enabling the first reinforcement structure 25 to enhance the structural strength of the connecting part 24 in both the radial and circumferential directions of the air guide ring 20, and having a better structural reinforcement effect.

[0082] Combined with Figure 3 and attached Figure 4 As shown in , in some examples, optionally, the first reinforcement structure 25 of this embodiment includes at least one first rib 252 disposed on the second surface 242 .

[0083] The first rib 252 may be arranged on the first surface 241 and / or the second surface 242, and in this embodiment, it is preferably arranged on the second surface 242. The number of the first ribs 252 arranged on the second surface 242 may be one or more, and the first rib 252 may extend from one end of the connecting portion 24 connected to the outer wall of the air guide ring 20 to the end of the connecting portion 24 away from the outer wall of the air guide ring 20, and the first rib 252 may be integrally formed with the connecting portion 24, or integrally connected to the second surface 242 of the connecting portion 24 by welding or hot melting.

[0084] In some examples, optionally, the length direction of the first rib 252 of this embodiment is arranged along the radial direction of the air guide ring 20, and of course, the length direction of the first rib 252 can also be arranged along the circumferential direction of the air guide ring 20. Alternatively, similar to the form of the first strip groove 2511 and the second strip groove 2512 described above, the number of the first rib 252 of this embodiment is two, and the two first ribs 252 intersect, one of the first ribs 252 is arranged along the radial direction of the air guide ring 20, and the other first rib 252 is arranged along the circumferential direction of the air guide ring 20, forming a cross-shaped reinforcement rib structure (this embodiment is not shown in the figure), so as to further improve the structural strength of the connecting portion 24.

[0085] In addition, it should be noted that the first rib 252 of this embodiment and the aforementioned groove 251 can exist at the same time or one of them can exist selectively. When both exist at the same time, they need to avoid each other in position.

[0086] Combined with the attachment again Figure 3 and attached Figure 4 As shown in , in some examples, optionally, the circumferential outer wall of the air guide ring 20 of this embodiment is provided with a second reinforcement structure 26, and the second reinforcement structure 26 can improve the structural strength of the circumferential side wall of the air guide ring 20 and reduce the possibility of deformation of the air guide ring 20.

[0087] In some examples, optionally, the second reinforcement structure 26 of the present embodiment includes a plurality of second ribs 261 arranged at intervals along the circumferential direction, and the length direction of the second ribs 261 can be set along a direction parallel to the axial direction of the air guide ring 20, and the axial direction of the air guide ring 20 refers to the direction from the air inlet 21 to the air outlet 23, or the direction from the air outlet 23 to the air inlet 21.

[0088] Furthermore, when the first reinforcement structure 25 of the present embodiment includes the above-mentioned first rib 252 arranged on the second surface 242, the first rib 252 and the second rib 261 are an integrally formed structure. In this way, the first rib 252 is formed at the same time as the second rib 261 is processed and formed, which is not only convenient for processing, but also the integral structure formed by the first rib 252 and the second rib 261 has better structural strength, thereby further improving the structural stability of the connecting portion 24.

[0089] In some examples, optionally, the second reinforcement structure 26 of the present embodiment further includes a plurality of third ribs 262, which are arranged around the circumferential outer wall of the air guide ring 20 and are arranged at intervals along the axial direction of the air guide ring 20, and each third rib 262 is connected to the plurality of second ribs 261.

[0090] The third rib 262 of this embodiment is in the shape of an annular or approximately annular shape, and the connection between the third rib 262 and the second rib 261 can be regarded as a part of the third rib 262, or a part of the second rib 261. The third rib 262 of this embodiment can be integrally connected with the second rib 261 or integrally formed during processing, and the two can be perpendicular to each other to form a grid-like reinforcing rib structure, which can effectively improve the structural strength of the side wall of the air guide ring 20 and further reduce the possibility of deformation of the side wall of the air guide ring 20.

[0091] The multiple third ribs 262 of the present embodiment can be evenly spaced along the axial direction of the air guide ring 20. Similarly, the second ribs 261 of the present embodiment can be evenly spaced along the circumferential direction of the air guide ring 20, so that the structural strength of the grid-like reinforcing ribs formed by the second ribs 261 and the third ribs 262 along the circumferential and axial directions is roughly equal, avoiding the existence of areas with excessive or insufficient strength.

[0092] Combined with Figure 4 As shown in , in some examples, optionally, the first reinforcement structure 25 is protruded from the connecting portion 24, the height of the first reinforcement structure 25 protruding from the connecting portion 24 is h, and the thickness of the side walls around the air guide ring 20 is H, where h and H satisfy: 0.1H <h<20H。

[0093] In addition, in order to improve the connection stability between the air guide ring 20 and the heat exchanger 10, a connection hole 27 or multiple connection holes 27 can be provided on the side walls around the air guide ring. The connection hole 27 is used to connect the sheet metal parts on the heat exchanger 10 (not shown in the figure).

[0094] Combined with Figure 5 As shown in , in some examples, optionally, a plurality of corners 12 are provided on the top of the side wall of the heat exchanger 10 of this embodiment, and a plurality of connecting parts 24 are installed on the plurality of corners 12 in a one-to-one correspondence.

[0095] The corner 12 described in the present embodiment can be directly the diagonal point of the cross section of the heat exchanger 10. For example, the cross section of the heat exchanger 10 shown in the figure has four diagonals (the side wall at one of the diagonals is missing), and the connecting parts 24 of the present embodiment are correspondingly arranged in four, and the four connecting parts 24 are located at the four diagonals in a one-to-one correspondence, so that the bottom of the air guide cover and the heat exchanger 10 can be better connected and matched, thereby improving the stability of the two after connection.

[0096] The second aspect of this embodiment provides a HVAC device, which has a HVAC device outdoor unit 100 of the above technical solution.

The specific structural forms of the heat exchanger are not listed one by one in this embodiment.

[0099] The heat exchanger 10 of this embodiment has a heat exchange chamber 11, or the inner wall of the heat exchanger 10 forms the heat exchange chamber 11. The specific structure of the heat exchange chamber 11 can be referred to in the following attached Figure 5 In the structure, the heat exchanger 10 is open at the top and bottom and has a notch 13 at one diagonal position.

[0100] On the outside of the air guide ring 20 of the present embodiment, the HVAC equipment outdoor unit 100 is provided with a protective shell 50 for protecting the air guide ring 20 and the fan blades 40 inside the air guide ring 20 .

[0101] On the outside of the heat exchanger 10 of the present embodiment, the HVAC equipment outdoor unit 100 is provided with an outer shell 30 for protecting its own internal structure. The outer shell 30 is provided with an air inlet grille 31. The airflow flowing into the outer shell 30 from the air inlet grille 31 can enter the lower part of the air guide ring 20 of the present embodiment and flow out from the top of the air guide ring 20, thereby completing the heat exchange inside the HVAC equipment outdoor unit 100.

[0102] The air guide ring 20 is connected to the protective shell 50 , and the protective shell 50 is detachably connected to the air guide ring 20 . The protective shell 50 can also be connected to the outer shell 30 , and the connection can be detachably connected.

[0103] Combined with Fig.15 As shown, in some examples, optionally, the protective shell 50 of the present embodiment includes a first sub-shell 51, a second sub-shell 52 and a ventilation plate 53, the first sub-shell 51 and the second sub-shell 52 form a cavity open at the top and bottom, the air guide ring 20 is located in the cavity, the ventilation plate 53 is connected to the upper opening of the cavity, and the ventilation plate 53 can be a grille structure with multiple ventilation holes.

[0105] Specifically, the first sub-shell 51 and the second sub-shell 52 can be directly detachably connected to the outer shell 30, or the first sub-shell 51 or the second sub-shell 52 can be detachably connected to the outer shell 30 through an intermediate medium. For example, the outer shell 30 is detachably connected to the air guide ring 20, and then the first sub-shell 51 and the second sub-shell 52 are detachably connected to the air guide ring 20 respectively, so as to realize the spaced detachable connection between the first sub-shell 51 and the second sub-shell 52 and the outer shell 30 respectively.

[0106] In some examples, optionally, the first sub-shell 51 and the second sub-shell 52 of this embodiment can be L-shaped as shown in the figure, and the two are connected to form a protective shell 50 that is approximately a rectangular frame. The above-mentioned detachable connection can be performed at the connection point between the first sub-shell 51 and the second sub-shell 52.

[0107] In addition, the first sub-shell 51 and the second sub-shell 52 can be designed to be detachably connected. The first sub-shell 51 and the second sub-shell 52 can be directly detachably connected, or the first sub-shell 51 and the second sub-shell 52 can be detachably connected to the air guide ring 20 respectively, and the first sub-shell 51 and the second sub-shell 52 can be indirectly detachably connected through the air guide ring 20.

[0108] For example Fig.16 As shown in the figure, a connection hole 27 or multiple connection holes 27 can be provided on the side walls around the air guide ring 20, and the connection hole 27 can be connected to connecting parts such as bolts and screws to detachably connect the first sub-shell 51 or the second sub-shell 52 of the protective shell 50, or to connect the outer shell 30, so as to realize the detachable connection between the air guide ring 20 and the protective shell 50 or the outer shell 30.

[0109] The above-mentioned "detachable connection" in this embodiment can be two components (such as the protective shell 50 and the outer shell 30, or the first sub-shell 51 and the second sub-shell 52) that are connected in a removable manner by bolt connection, screw connection, snap connection, and plug-in connection, which are not listed one by one in this embodiment.

[0110] The air guide ring 20 of this embodiment is located above the heat exchanger 10 and is connected to the heat exchange cavity 11. Specifically, the air guide ring 20 may be provided with an air inlet 21, an air guide channel 22 and an air outlet 23 that are connected in sequence, the radial dimensions of the air inlet 21 and the air outlet 23 may be larger than the radial dimension of the air guide channel 22, the air guide channel 22 is used to accommodate the fan blades 40 of the outdoor unit 100 of the HVAC equipment, and the outer wall of the air guide ring 20 at the air inlet 21 is provided with a connecting portion 24, and the connecting portion 24 is located on the top of the housing 30 of the heat exchanger 10.

[0111] The connection parts 24 of this embodiment are arranged at intervals along the circumferential direction of the bottom of the air guide ring 20, and the connection parts 24 extend outward radially along the air guide ring 20. The connection parts 24 can be connected to the top of the outer shell 30 of the heat exchanger 10. The connection method can be a detachable connection method such as snap-on, bolt connection, plug-in, etc., or the connection part 24 can directly abut the top of the outer shell 30.

[0112] The connection part 24 of this embodiment can be a plate-like structure or a block-like structure. The multiple connection parts 24 can not only improve the stability of the air guide ring 20 installed on the heat exchange chamber 11, but also do not need a circumferentially surrounding connection structure like some existing ones. The multiple connection parts 24 are arranged at intervals along the circumference to save materials, thereby reducing a certain production cost.

[0113] Combined with Fig.17 and 18 As shown, different from the first reinforcing structure 25 in the first embodiment, the first reinforcing structure 25 of this embodiment includes at least one first reinforcing rib 253 disposed on the first surface 241. It can be understood that the first reinforcing rib 253 of this embodiment and the first rib plate 252, the second rib plate 253 and the third rib plate 254 can be identical or similar in structure, and the difference in the names of the reinforcing rib and the rib plate is only for distinguishing the two.

[0114] The first reinforcing rib 253 may be a raised strip structure formed on the first surface 241, or may be a recess 243 formed by machining on the first surface 241, with a raised first reinforcing rib 253 provided in the recess 243. In this embodiment, preferably, a recess 243 is provided on the first surface 241, and the recess 243 may be understood as a depression or a groove occupying most of the area of ​​the first surface 241. The first reinforcing rib 253 is formed in the recess 243, and the first reinforcing rib 253 and the recess 243 may be integrally connected or integrally formed during machining, and each first reinforcing rib 253 connects two opposite side walls of the recess 243, and the side walls may be straight or curved.

[0115] When the first reinforcing rib 253 is arranged in the recess 243, the overall thickness and consumables of the connecting part 24 can be reduced, the space occupied by the connection can be reduced to facilitate the installation of the connecting part 24, and it has better economy and will not affect the installation of the connecting part 24 and the top of the heat exchanger 10.

[0116] In some examples, optionally, there are multiple first reinforcing ribs 253, and the multiple first reinforcing ribs 253 include multiple first sub-reinforcing ribs 2531 and multiple second sub-reinforcing ribs 2532. Specifically, it can be understood that the multiple first reinforcing ribs 253 include two parts, wherein the multiple first reinforcing ribs 253 of one part are named as multiple first sub-reinforcing ribs 2531, and the multiple first reinforcing ribs 253 of the other part are named as multiple second sub-reinforcing ribs 2532, so as to facilitate the distinction and description of the first sub-reinforcing ribs 2531 and the second sub-reinforcing ribs 2532, the multiple first sub-reinforcing ribs 2531 are arranged at intervals along a first direction X parallel to the first surface 241, and the multiple second sub-reinforcing ribs 2532 are arranged at intervals along a second direction Y parallel to the first surface 241, and the first direction X and the second direction Y intersect.

[0117] In this embodiment, the first direction X can be perpendicular to or form an acute angle with the second direction Y. The opposite ends of the first sub-reinforcement rib 2531 are respectively connected to two side walls of the recess 243 in a one-to-one correspondence, and the opposite ends of the second sub-reinforcement rib 2532 are respectively connected to the other two side walls of the recess 243 in a one-to-one correspondence, so as to ensure that the first sub-reinforcement rib 2531 and the second sub-reinforcement rib 2532 form a reinforcement structure with the recess 243, thereby improving the structural strength of the connecting portion 24.

[0118] In some examples, optionally, at least part of the plurality of first sub-reinforcement ribs 2531 and at least part of the plurality of second sub-reinforcement ribs 2532 of this embodiment intersect to form a grid structure. The grid-like reinforcement ribs have better structural strength and stability than a plurality of simple strip-shaped reinforcement ribs, thereby improving the structural durability and safety of the connection portion 24.

[0119] Combined with the attachment again Figure 14-16 As shown, similar to the first embodiment, the first reinforcement structure 25 of this embodiment further includes at least one first rib 252 disposed on the second surface 242 .

[0120] The first rib 252 can be arranged on the first surface 241 and / or the second surface 242. Since the first surface 241 is already provided with a large-area first reinforcing rib 253, it is preferably arranged on the second surface 242 in this embodiment. The ratio of the height h of the first rib protruding from the second surface to the thickness H of the surrounding side walls of the air guide ring can be in the range of 0.1 to 20, so as to ensure that the first rib can ensure the structural strength.

[0121] The number of the first ribs 252 on the second surface 242 may be one or more. The first ribs 252 may extend from one end where the connecting portion 24 is connected to the outer wall of the air guide ring 20 to the end of the connecting portion 24 away from the outer wall of the air guide ring 20. The first ribs 252 may be integrally formed with the connecting portion 24, or integrally connected to the second surface 242 of the connecting portion 24 by welding, hot melting or the like.

[0122] In some examples, optionally, the length direction of the first rib 252 of this embodiment is arranged along the radial direction of the air guide ring 20. Of course, the length direction of the first rib 252 can also be arranged along the circumferential direction of the air guide ring 20. Alternatively, the number of the first ribs 252 of this embodiment is two, and the two first ribs 252 intersect, one of the first ribs 252 is arranged along the radial direction of the air guide ring 20, and the other first rib 252 is arranged along the circumferential direction of the air guide ring 20, forming a cross-shaped reinforcement rib structure (this embodiment is not shown in the figure), so as to further improve the structural strength of the connecting portion 24.

[0123] In some examples, optionally, the circumferential outer wall of the air guide ring 20 of the present embodiment is provided with a second reinforcement structure 26, and the second reinforcement structure 26 can improve the structural strength of the circumferential side wall of the air guide ring 20 and reduce the possibility of deformation of the air guide ring 20.

[0124] In some examples, optionally, the second reinforcement structure 26 of the present embodiment includes a plurality of second ribs 261 arranged at intervals along the circumferential direction, and the length direction of the second ribs 261 can be set along a direction parallel to the axial direction of the air guide ring 20, and the axial direction of the air guide ring 20 refers to the direction from the air inlet 21 to the air outlet 23, or the direction from the air outlet 23 to the air inlet 21.

[0125] Furthermore, when the first reinforcement structure 25 of the present embodiment includes the above-mentioned first rib 252 arranged on the second surface 242, the first rib 252 and the second rib 261 are an integrally formed structure. In this way, the first rib 252 is formed at the same time as the second rib 261 is processed and formed, which is not only convenient for processing, but also the integral structure formed by the first rib 252 and the second rib 261 has better structural strength, thereby further improving the structural stability of the connecting portion 24.

[0126] In some examples, optionally, the second reinforcement structure 26 of the present embodiment further includes a plurality of third ribs 262, which are arranged around the circumferential outer wall of the air guide ring 20 and are arranged at intervals along the axial direction of the air guide ring 20, and each third rib 262 is connected to the plurality of second ribs 261.

[0127] The third rib 262 of this embodiment is in the shape of an annular or approximately annular shape, and the connection between the third rib 262 and the second rib 261 can be regarded as a part of the third rib 262, or a part of the second rib 261. The third rib 262 of this embodiment can be integrally connected with the second rib 261 or integrally formed during processing, and the two can be perpendicular to each other to form a grid-like reinforcing rib structure, which can effectively improve the structural strength of the side wall of the air guide ring 20 and further reduce the possibility of deformation of the side wall of the air guide ring 20.

[0128] The multiple third ribs 262 of the present embodiment can be evenly spaced along the axial direction of the air guide ring 20. Similarly, the second ribs 261 of the present embodiment can be evenly spaced along the circumferential direction of the air guide ring 20, so that the structural strength of the grid-like reinforcing ribs formed by the second ribs 261 and the third ribs 262 along the circumferential and axial directions is roughly equal, avoiding the existence of areas with excessive or insufficient strength.

[0129] In some examples, optionally, a plurality of corners 12 are provided on the top of the side wall of the heat exchanger 10 of the present embodiment, and a plurality of connecting portions 24 are installed on the plurality of corners 12 in a one-to-one correspondence.

[0130] The corner 12 described in the present embodiment can be directly the diagonal point of the cross section of the heat exchanger 10. For example, the cross section of the heat exchanger 10 shown in the figure has four diagonals (the side wall at one of the diagonals is missing), and the connecting parts 24 of the present embodiment are correspondingly arranged in four, and the four connecting parts 24 are located at the four diagonals in a one-to-one correspondence, so that the bottom of the air guide cover and the heat exchanger 10 can be better connected and matched, thereby improving the stability of the two after connection.
