[0064] Embodiment One

[0065] With reference to FIGS. 1-3, the embodiments of the present application provide an outdoor unit 100 of a heating and ventilation device, which includes a shell 10, and a heat exchanger assembly 20, a guide ring 30, a bracket 40, and a fan assembly 50 located in the shell 10.

[0066] The shell 10 of the embodiments serves as a protective and accommodating structure of the outdoor unit, which can be made of metal or plastic with certain structural strength. The shell 10 includes a base (not labeled in the figures) and a plurality of side walls located above the base and surrounding the base. In some embodiments, the top of the shell 10 can also be provided with an air outlet mesh 15 as a top wall. Taking the shell 10 as a rectangular box for example, the plurality of side walls of the embodiments include two first side walls 11 and two second side walls 12. The first side walls 11 and the second side walls 12 can be an integral structure or a detachable split structure. The two first side walls 11 are oppositely arranged along a second direction Y, and the two second side walls 12 are oppositely arranged along a first direction X. One of the second side walls 12 can be regarded as a front panel of the shell 10, and the other of the second side walls 12 can be regarded as a rear panel of the shell 10.

[0067] The first direction X is a direction intersecting the air inlet side 31 and the air outlet side 32 of the air guide ring 30, and specifically, the first direction X can be perpendicular to the direction of the air inlet side 31 and the air outlet side 32. In actual application of the outdoor unit, the first direction X and the second direction Y can be horizontal directions, and the first direction X can be perpendicular to the second direction Y.

[0068] The two first side walls 11 and the two second side walls 12 form an open-top accommodating cavity, the top opening of which is the air outlet 101 of the shell 10, and the bottom opening is an air inlet (not labeled in the figure). The heat exchanger assembly 20, the air guide ring 30, the bracket 40, and the fan assembly 50 are all located in the accommodating cavity.

[0069] The heat exchanger assembly 20 of the embodiment is located in the accommodating cavity. The heat exchanger assembly 20 can have a structure with a cross section approximately rectangular or circular. The heat exchanger assembly 20 can include an air heat exchanger in related technologies, and thus, the specific structure of the heat exchanger assembly 20 will not be described in detail in the embodiment. The heat exchanger assembly 20 has a heat exchange cavity, or the inner wall of the heat exchanger assembly 20 forms the heat exchange cavity.

[0070] The air guide ring 30 of the embodiment is located between the heat exchanger assembly 20 and the air outlet 101, and has an air inlet side 31 facing the heat exchanger assembly 20 and an air outlet side 32 facing the air outlet 101. The "side" in the air inlet side 31 and the air outlet side 32 can refer to a side edge or a side portion. The inner wall of the air guide ring 30 surrounds an air guide hole, which is in communication with the heat exchange cavity and the air outlet 101. In actual application, the air guide ring 30 can be used to collect air flow to increase the air flow rate of the heat exchange cavity of the heat exchanger assembly 20.

[0071] The fan assembly 50 includes a motor 51 and a fan blade 52 in transmission connection. The motor 51 is at least partially located in the air guide ring 30, and the fan blade 52 is located in the air guide ring 30. The motor 51 drives the fan blade 52 to rotate, so that the air in the heat exchange cavity is sequentially discharged through the air inlet side 31 and the air outlet side 32 of the air guide ring 30 and the air outlet 101 of the shell 10.

[0072] Different from the embodiment in the related art that the bracket 40 is installed at the air inlet side 31, the embodiment adopts the embodiment that the bracket 40 is installed between the air outlet 101 and the air outlet side 32, the bracket 40 can have a certain interval with the air outlet side 32 and the air outlet 101 respectively, the bracket 40 can be directly installed on the above-mentioned side wall of the shell 10, can also be installed on the air guide ring 30 (this kind of embodiment is not shown in the figure), and can also be installed on the air outlet net 15 of the shell 10, as long as the bracket 40 is located at the air outlet side of the air guide ring 30. The motor 51 is installed on the bracket 40, and in the actual application of the heating and ventilation equipment outdoor unit 100, the motor 51 is located below the bracket 40, so the motor 51 can be regarded as being hung on the bracket 40.

[0073] The reason why the bracket 40 arranged near the air inlet side 31 of the air guide ring 30 affects the airflow is that the air inlet side 31 of the air guide ring 30 is a buffer area connecting the heat exchange cavity and the air guide hole, the airflow has certain flow change at the air inlet side 31, and the stability is poor, so the bracket 40 existing at this position will amplify the influence on the stability of the airflow. When located at the air outlet side of the air guide ring 30, the air outlet 101 and the air outlet side 32 of the air guide ring 30 are connected with the outside, and are not a buffer area connecting two cavities, so the disturbance of the bracket 40 to the airflow at the air outlet 101 is small, and the bracket 40 will not cause too much influence on the airflow at the air outlet, and can reduce or even eliminate the possibility of disturbing the airflow at the air inlet side of the air guide ring 30, thereby improving the stability and flow speed of the airflow at the air inlet side 31 of the air guide ring 30.

[0074] In combination with the figures 4 and 5, in some examples, the bracket 40 of the embodiment can optionally include a support 41, which can be a rod-shaped structure, and the cross-sectional shape of the support 41 can be any one of a circle, an ellipse, a triangle, a cone, etc., which are not enumerated one by one in the embodiment.

[0075] The support 41 is installed on the shell 10 at opposite ends in the first direction X, and the specific connection mode of the support 41 and the shell 10 is given below. The fan assembly 50 is installed on the support 41, and specifically, the motor 51 of the fan assembly 50 is installed on the support 41, and the connection mode of the motor 51 and the support 41 can be a mechanical connection mode such as bolt connection, clamping, riveting, etc., which are not enumerated one by one in the embodiment.

[0076] In some examples, optionally, the number of the support 41 is multiple, and the multiple support 41 can be arranged in the second direction Y at intervals, and the multiple refers to two or more than two, for example, two support 41 in the figure, and compared with the single support 41, the two or more support 41 can be more stably connected with the motor 51, and the stability of the motor 51 hoisted on the support 40 is improved.

[0077] In order to realize the installation of the support 40, the shell 10 is designed to include two first beams 13, which can be regarded as a part of the second side wall 12 or independent of the second side wall 12, and the two first beams 13 are connected to the plate body of the two second side walls 12 one by one, and the two first beams 13 are oppositely arranged along the first direction X and connected to the top of the two first side walls 11, and the opposite ends of the support 41 are connected to the two first beams 13, and the connection mode can be plug-in, clamping, bolt connection, riveting and the like.

[0078] In some examples, optionally, the top of the first beam 13 is provided with a connecting groove 131, and one end of the support 41 is provided with a connecting part 411, which extends downward in the direction away from the air outlet 101, and at least part of the connecting part 411 is inserted into the connecting groove 131.

[0079] Further, in order to improve the connection stability of the two supports 41 and the two first beams 13, the structure of the connecting groove 131 is improved in the embodiment, and the first beam 13 is provided with a boss on the outer side away from the air guide ring 30 or the accommodating cavity of the shell 10, and the connecting groove 131 starts on the boss, and the connecting groove 131 is open at the end away from the one end of the support 41 along the first direction X, and the upper end of the connecting groove 131 is also open, and the width of the connecting groove 131 in the second direction Y gradually decreases from the end away from the one end of the support 41 to the end close to the one end of the support 41, so that the connecting groove 131 forms a necked structure, and in this way, the connecting part 411 can more easily enter the connecting groove 131 through the opening of the connecting groove 131, and as the connecting part 411 gradually moves to the inside of the connecting groove 131, the connecting groove 131 can clamp the connecting part 411, so as to realize the positioning connection of the two.

[0080] In addition to the above connection mode of the connecting groove 131 and the connecting part 411, in some examples, optionally, the connecting part 411 and the connecting groove 131 of the embodiment can be connected by a third connecting piece (not shown in the figure) such as a screw, an anchor nail or the like. Or the connecting part 411 and the connecting groove 131 are connected in interference, so that the connecting part 411 extrudes the connecting groove 131, so as to improve the connection stability of the two. Or the connecting part 411 and the connecting groove 131 are connected in interference at the same time, and the connecting part 411 and the connecting groove 131 of the embodiment are connected by a third connecting piece such as a screw, an anchor nail or the like.

[0081] In addition to being used for mounting the support 41, the first beams 13 of the present embodiment can also be used for positioning the wind deflector 30. Specifically, the wind deflector 30 can be provided with one or two first positioning portions (not shown in the drawings), and the one or two first beams 13 are provided with second positioning portions 132, and the first positioning portions and the second positioning portions 132 are one-to-one matched and connected.

[0082] The "positioning" described in the present embodiment refers to the fixing of the position of the wind deflector 30 during installation. Therefore, the first positioning portions and the second positioning portions 132 of the present embodiment can have various structural forms. For example, the first positioning portions and the second positioning portions 132 are both positioning holes, and the first positioning portions and the second positioning portions 132 are connected and positioned by means of bolts or screws or the like. Alternatively, the first positioning portions can be one of a positioning slot and a positioning protrusion, and the second positioning portions 132 can be the other of the positioning slot and the positioning protrusion.

[0083] In some examples, the housing 10 further comprises two second beams 14 located below the two first beams 13. The material of the second beams 14 can be the same as or similar to that of the first beams 13. The second beams 14 can be regarded as part of the second side walls 12 or as an independent part of the housing 10. The two second beams 14 are oppositely arranged along the first direction X and connected to the two first side walls 11. The connection of the second beams 14 to the two first side walls 11 can improve the structural stability of the housing 10.

[0084] In order to improve the positioning and installation accuracy of the wind deflector 30, in some examples, the present embodiment is further provided with a third positioning portion (not shown in the drawings) on the wind deflector 30.

[0090] Based on the above-mentioned HVAC outdoor unit 100, the embodiment further provides an HVAC device including the HVAC outdoor unit 100 shown in the above technical solution. In some embodiments, the HVAC device further includes an indoor unit (not shown in the figure). The structure of the indoor unit and other parts of the HVAC device except the indoor unit and the outdoor unit are described in the prior art, and will not be described here.

[0091] Embodiment two

[0092] The embodiment provides an HVAC outdoor unit 100, which is different from the above-mentioned embodiment one in the position and installation mode of the bracket 40. The HVAC outdoor unit 100 of the embodiment will be introduced below in combination with the accompanying drawings 7-20.

[0093] In combination with the accompanying drawings 7 and 8, the embodiment provides an HVAC outdoor unit 100, which includes a shell 10, a heat exchanger assembly 20 (shown in the above-mentioned embodiment, the heat exchanger assembly 20 is not shown in the accompanying drawings of the embodiment), a guide ring 30, a bracket 40, and a fan assembly 50.

[0094] The shell 10 is taken as a protection and accommodation structure of the HVAC outdoor unit 100, which can be made of metal or plastic with certain structural strength.

[0095] In some embodiments, optionally, the shell 10 of the present embodiment can be distinguished from the shell 10 structure of the above-mentioned embodiments, the shell 10 of the present embodiment comprises an upper shell 16 and a lower shell 17, the upper shell 16 and the lower shell 17 can be docked by mechanical connection methods such as clamping, welding, bolting, etc., the upper shell 16 is provided with an air outlet 101, and the upper shell 16 can be provided with the above-mentioned air guide ring 30, support 40 and fan assembly 50, the lower shell 17 is provided with the heat exchanger assembly 20, and the side wall of the lower shell 17 can be a grating structure capable of ventilation.

[0096] The structure of the heat exchanger assembly 20 and the air guide ring 30 has been described in the above-mentioned embodiments, and will not be described in detail in this embodiment. This embodiment only describes the technical solutions that are different from the above-mentioned embodiments.

[0097] Unlike the above-mentioned embodiments, the support 40 is directly installed on the top area of the shell 10, and the support 40 only comprises two support members 41, the support 40 of the present embodiment comprises a support ring 42 and a carrier 43, the support ring 42 refers to a closed loop structure with a shape of a ring or similar to a ring.

[0098] For example, the outer periphery of the support ring 42 shown in the figure is approximately rectangular, and the inner periphery is approximately ring-shaped. The specific shape of the support ring 42 is adapted to the actual product shape, so although this embodiment is called a support ring 42, it is not necessarily a ring (loop) shape, but can also be other similar closed loop shapes.

[0099] The side of the air guide ring 30 facing the air outlet 101 can be the upper side of the air guide ring 30, the support ring 42 is directly seated on the upper side of the air guide ring 30, and the support ring 42 also forms a mechanical connection relationship with the shell 10, thereby improving the stability of the installation of the support ring 42. The mechanical connection relationship between the support ring 42 and the shell 10 is described in detail below.

[0100] The carrier 43 of the present embodiment is installed on the support ring 42, and the installation method can be any fixed connection method or detachable connection method. The carrier 43 has a function similar to the support member 41 in Embodiment 1, and is also used to install and support the fan assembly 50.

[0101] The carrier 43 of the present embodiment is installed on a support ring 42, and the support ring 42 is fixed by the air guide ring 30 and the shell 10. Compared with the structure and installation method of the support 40 of the present embodiment, the support 40 of the present embodiment can be completely hidden inside the shell 10, thereby improving the appearance and integrity of the heating and ventilation equipment outdoor unit 100.

[0102] Compared with the form of mounting the fan assembly 50 by two first cross beams 13 and two support members 41 in Embodiment One, the present embodiment first uses the air guide ring 30 as a load-bearing structure of the support ring 42, then connects the support ring 42 with the shell 10, and then uses the carrier 43 to carry the fan assembly 50, which can further improve the mounting stability of the fan assembly 50 and improve the structural strength and stability of the support 40.

[0103] In combination with FIG. 9, in some embodiments, optionally, the carrier 43 of the present embodiment can include a plurality of carrier portions 431 and mounting portions 432. The shape of the carrier portion 431 can be a rod, a strip, a block, or a plate, etc., which will not be enumerated one by one in the present embodiment.

[0104] Taking the rod-shaped carrier portion 431 in the figure as an example, the length direction of each carrier portion 431 can be arranged along one of the radial directions of the support ring 42. One end of the carrier portion 431 is mounted on the support ring 42, and the mounting mode can be any one of mechanical connection modes, such as bolt connection, welding, clamping, and insertion.

[0105] The other end of the carrier portion 431 is connected with the mounting portion 432 in a fixed connection mode, such as welding or one-piece forming during processing. The plurality of carrier portions 431 are arranged along the circumferential direction of the support ring 42 on the support ring 42, and specifically, the plurality of carrier portions 431 can be uniformly and evenly arranged along the circumferential direction of the support ring 42.

[0106] In some embodiments, optionally, the mounting portion 432 can be provided with a weight-reducing hole 4321, which can be arranged at the center and / or the periphery of the mounting portion 432. The mounting portion 432 can be provided with a connecting hole 4322 at the periphery, which is used to connect the fan assembly 50 by means of a bolt or the like.

[0107] In combination with FIGS. 10 and 11, in order to save space and improve the mounting stability of the carrier portion 431, in some embodiments, optionally, the side (i.e., the upper side) of the support ring 42 facing the air outlet 101 is provided with a first accommodating groove 421. The shape and size of the first accommodating groove 421 are greater than or equal to the shape and size of one end of the carrier 43, so that one end of the carrier 43 can be accommodated in the first accommodating groove 421, and the carrier 43 is mounted in the first accommodating groove 421 by means of mechanical connection modes such as bolt connection, welding, and insertion.

[0108] The presence of the first accommodating groove 421 can make the carrier portion 431 located inside the support ring 42 or inside the air guide ring 30, and the carrier 43 will not exceed the upper surface of the support ring 42, so that the carrier portion 431 will not occupy the space above the support ring 42, thereby reducing the thickness of the entire support 40.

[0109] In addition, since one end of the bearing member 43 is accommodated in the first accommodation groove 421, the side wall and the bottom wall of the first accommodation groove 421 can limit the one end of the bearing member 43, thereby further improving the connection stability of the bearing part 431 and the support ring 42.

[0110] In some embodiments, optionally, the first accommodation groove 421 is recessed from the support ring 42 in a direction away from the air outlet 101, that is, the upper surface of the support ring 42 is recessed downward to form the first accommodation groove 421, and the bottom wall and part of the side wall of the first accommodation groove 421 protrude from the lower surface of the support ring 42 to form a protruding structure.

[0111] Such a structure makes the protruding structure formed by the first accommodation groove 421 accommodated in the air guide ring 30, further reducing the space occupied by the bracket 40 in the vertical direction.

[0112] Again, as shown in FIG. 8, correspondingly, in order to match the protruding structure of the first accommodation groove 421 protruding from the lower surface of the support ring 42, so that the support ring 42 can be more stably placed on the air guide ring 30, the upper side (air outlet side 32) of the air guide ring 30 of the embodiment is provided with an avoidance groove 321 for accommodating the protruding structure or the bearing member 43.

[0113] Taking the avoidance groove 321 accommodating the protruding structure (the bottom wall and at least part of the side wall of the first accommodation groove 421) as an example, the size of the avoidance groove 321 can be just engaged with the protruding structure of the first accommodation groove 421, thereby improving the stability of the support ring 42 placed on the air guide ring 30.

[0114] In combination with FIGS. 10-15, in some embodiments, optionally, the structure of the support ring 42 is further improved in the embodiment, a plurality of convex edges 422 are arranged on the edge of the inner wall of the support ring 42. For the convenience of understanding, the inner edge of the convex edge 422 is shown by a dashed line in FIG. 10 of the embodiment.

[0115] The plurality of convex edges 422 of the embodiment are arranged along the circumferential direction of the support ring 42, and the convex edges 422 are used to be placed on the upper side of the air guide ring 30, so that the support ring 42 abuts against the upper side of the air guide ring 30 by the plurality of convex edges 422.

[0116] Of course, in addition to the way of using the convex edges 422 to realize the placement of the support ring 42 on the air guide ring 30, the inner edge of the support ring 42 can also be directly abutted against the upper side of the air guide ring 30.

[0117] In some embodiments, optionally, a first flange part 4221 can be extended on the convex edge 422, and the first flange part 4221 is used to fit the inner wall surface of the air guide ring 30.

[0118] Again, in combination with FIG. 1 and FIG. 2, in some embodiments, optionally, the upper shell 16 comprises a top cover 161 and a first peripheral wall 162 connected to the top cover 161, and the top cover 161 is provided with a ventilation grille 1611 at a portion of the top cover 161 opposite to the air guide hole of the air guide ring 30 along the axial direction of the air guide ring 30 (the third direction Z perpendicular to the first direction X and the second direction Y in the figure).

[0119] The top cover 161 is provided with a ventilation grille 1611 at a portion of the top cover 161 opposite to the air guide hole of the air guide ring 30, which can be understood as that the ventilation grille 1611 is provided at all or part of the portion of the top cover 161 opposite to the air guide hole, and the ventilation grille 1611 is located at the air outlet 101, and the airflow in the air guide ring 30 can be discharged outside the machine body through the ventilation grille 1611.

[0120] In combination with FIG. 16 and FIG. 17, in some embodiments, optionally, a side of the first peripheral wall 162 facing the top cover 161 is provided with a third flange portion 1621 extending to the direction of the inner cavity of the upper shell 16, the third flange portion 1621 can be perpendicular to the inner wall surface of the first peripheral wall 162 or form an angle with the inner wall surface of the first peripheral wall 162, and the top cover 161 can be directly seated on the third flange portion 1621, so that the top cover 161 abuts against the second flange portion.

[0121] Such a structure design can support the top cover 161 by the first peripheral wall 162, thereby improving the stability of the top cover 161.

[0122] Further, in order to better support the top cover 161 and improve the sealing performance at the connection between the top cover 161 and the first peripheral wall 162, the top cover 161 is further improved in the embodiment.

[0123] Again, in combination with FIG. 16 and FIG. 17, in some embodiments, optionally, the outer periphery of the top cover 161 is provided with a first support edge 1612 and a second support edge 1613, wherein the first support edge 1612 extends downward and can be perpendicular to the top cover 161, and the first support edge 1612 is used to abut against the third flange portion 1621 described above.

[0124] Further, the second support edge 1613 is arranged around the first support edge 1612 and located outside the first support edge 1612, the second support edge 1613 abuts against the outside of the third flange portion 1621 (or the first peripheral wall 162), and the second support edge 1613 is used to block impurities such as dust and water from the outside from entering the connection between the top cover 161 and the first peripheral wall 162, thereby improving the sealing performance.

[0125] In a cross section parallel to the axial direction of the air guide ring 30 (the third direction Z in the figure), the length direction of the second support edge 1613 forms an angle with the length direction of the first support edge 1612 and the length direction of the third flange portion 1621, respectively, and the angle can be greater than 0° and less than 90°, and further, the angle can be 30° to 80°.

[0126] For example, in the case where the third flange portion 1621 is perpendicular to the first peripheral wall 162, in a cross section parallel to the axial direction of the air guide ring 30, the first support edge 1612, the second support edge 1613, and the third flange portion 1621 form a triangular support or a trapezoidal support structure, which not only improves the sealing performance of the connection between the top cover 161 and the first peripheral wall 162, but also further improves the support stability of the top cover 161.

[0127] In some embodiments, optionally, the top cover 161 and the third flange portion 1621 are detachably connected by a first connecting member (not shown in the figure), and / or the top cover 161 and the support ring 42 are detachably connected by the first connecting member.

[0128] The above technical solutions include three implementation manners. One is that the top cover 161 and the third flange portion 1621 are detachably connected by the first connecting member, and at the same time, the top cover 161 and the support ring 42 are detachably connected by the first connecting member, which can maximize the installation stability of the top cover 161, but the disassembly and assembly are relatively complex.

[0129] Another is that the top cover 161 and the third flange portion 1621 are detachably connected by the first connecting member, and the top cover 161 and the support ring 42 do not have a connection relationship. The third is that the top cover 161 and the support ring 42 are detachably connected by the first connecting member, and the top cover 161 and the third flange portion 1621 do not have a connection relationship. The latter two implementation manners are more convenient for disassembly and assembly of the top cover 161, thereby facilitating opening of the top cover 161 for maintenance of the internal structure of the machine body.

[0130] The first connecting member can be a bolt, a screw, or the like, or can be a buckle structure, and correspondingly, a threaded hole or a clamping groove or the like can be configured on the third flange portion 1621 or the support ring 42 to realize detachable connection of the top cover 161 with the support ring 42 and / or the third flange portion 1621.

[0131] Again in combination with FIGS. 1 and 2, in some embodiments, optionally, along the axial direction of the air guide ring 30 (the third direction Z in the figure), the part of the top cover 161 opposite to the fan assembly 50 is a closed solid structure 1614.

[0132] The top cover 161 designed in such a structure comprises at least three parts, one part is the ventilation grille 1611, another part is the peripheral part surrounding the grille and provided with the first support edge 1612 and the second support edge 1613 described above, and the third part is the solid structure 1614. The solid structure 1614 can be concentrically arranged with the ventilation grille 1611, and the solid structure 1614 is located in the central region of the top cover 161, and the ventilation grille 1611 surrounds the solid structure 1614.

[0133] In such a structure, the solid part blocks the direct ventilation above the fan assembly 50, avoids the mixing of cold and hot airflows (i.e. "airflow short circuit"), ensures that the external cold air is uniformly sucked from all around, and the hot air is effectively discharged from the side, thereby improving the heat exchange efficiency.

[0134] Moreover, the solid part shields the motor 51 and other key components of the fan assembly 50, reduces the direct entry of rain, dust and fallen leaves, reduces the corrosion and blockage risk of the motor 51, and plays a better protection role. In addition, it can also reduce the transmission of the noise of the fan assembly 50 and reduce the overall noise of the machine body. In addition, the solid part can be used as a structural support to improve the structural strength of the top cover 161, for example, to improve the pressure resistance of the top cover 161 (such as resisting snow, hail or accidental trampling). Finally, the local solid structure 1614 is easier to mold than the full ventilation grille 1611, thereby reducing production costs.

[0135] Regarding the connection of the support ring 42 and the shell 10, various embodiments are also provided in the present embodiment. For example, as shown in FIG. 18, a plurality of support columns 171 can be arranged on the inner wall of the lower shell 17, and the outer circumferential surface of the support ring 42 is provided with a protruding part protruding radially along the air guide ring 30 and protruding from the air guide ring 30, and the protruding part is mounted on the plurality of support columns 171. For another example, the support ring 42 can also be connected with the side wall of the lower shell 17 through a third connecting member (not shown in the figure) such as a bolt or a screw.

[0136] The two connection modes of the support ring 42 and the shell 10 can be combined or used alternatively, and both can fix the support ring 42 well and facilitate the installation of the support ring 42.

[0137] As shown in FIGS. 19 and 20, in some embodiments, the outer side of the support ring 42 is provided with a second flange part 423 extending downward, and the first flange part 4221 and the second flange part 423 have a predetermined interval therebetween, and the first flange part 4221, the second flange part 423 and the end surface of the air guide ring 30 therebetween jointly enclose an annular second accommodating groove 424.

[0138] The air outlet side 32 of the air guide ring 30 is located in the second accommodating groove 424, and the air outlet side 32 of the air guide ring 30 is provided with a first annular support portion 322 and a second annular support portion 323 surrounding the first annular support portion 322, the inner wall surface of the first annular support portion 322 is an inclined surface or an arc-shaped surface relative to the axial direction of the air guide ring 30, and the first flanging portion 4221 described above is fitted with the first annular support portion 322 of the embodiment.

[0139] The position of the support ring 42 between the first flanging portion 4221 and the second flanging portion 423 is the bottom wall of the second accommodating groove 424, the second annular support portion 323 abuts against the bottom wall of the second accommodating groove 424, so that the second flanging portion 423 can be used for sealing and dust prevention.

[0140] The second annular support portion 323 can give the support ring 42 a force in the axial direction (third direction Z) of the air guide ring 30, and especially when the support ring 42 is connected in the housing 10 only by the four support columns 171, the second annular support portion 323 can assist the support of the support ring 42 in the circumferential direction, thereby reducing the possibility of the air guide ring 30 being concave to the heat exchanger assembly 20.

[0141] Moreover, the fitting of the first annular support portion 322 and the first flanging portion 4221 can give the support ring 42 forces intersecting the first direction X, the second direction Y and the third direction Z respectively, forming multiple dimensions of support to the support ring 42, which can further improve the stability of the support ring 42 and better support and fix the support ring 42.

[0142] In some embodiments, optionally, along the radial direction of the air guide ring 30, the second annular support portion 323 can protrude from the outer wall surface of the air guide ring 30 to increase the spacing between the first annular support portion 322 and the second annular support portion 323, thereby expanding the width of the support of the support ring 42 by the first annular support portion 322 and the second annular support portion 323.

[0143] In some embodiments, optionally, the end surface of the air outlet side 32 of the air guide ring 30 of the embodiment is provided with an annular wind-blocking protrusion 324, the annular wind-blocking protrusion 324 is located on the inner side of the first annular support portion 322 and can be located on the innermost side of the end surface of the air outlet side 32, and the annular wind-blocking protrusion 324 extends along the circumferential direction of the air guide ring 30.

[0144] The annular wind-blocking protrusion 324 and the first annular support portion 322 have a certain spacing therebetween, and together they enclose an annular third accommodating groove 325, and the side (lower side or lower end) of the first flanging portion 4221 of the embodiment facing the air guide ring 30 extends into the third accommodating groove 325.

[0145] The design is considered that the air flow is easy to flow out through the gap between the first flange part 4221 and the first annular support part 322, and is easy to affect the stability of the air flow and the heat exchange effect, and by extending the lower side of the first flange part 4221 into the third accommodating groove 325, the annular wind blocking protrusion 324 (the inner side wall of the third accommodating groove 325) is used to block the air flow from entering the gap between the first flange part 4221 and the first annular support part 322, thereby improving the stability of the air flow.

[0146] Based on the above-mentioned HVAC outdoor unit 100, the present embodiment further provides an HVAC device, which comprises the above-mentioned HVAC outdoor unit 100, and in some embodiments, the HVAC device further comprises an indoor unit (not shown in the figure), and the structure of the indoor unit and other parts of the HVAC device except the indoor unit and the outdoor unit can refer to the prior art, which will not be described herein.

[0147] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
