[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] In the description of this utility model, it should be understood that the terms "axial", "radial", "circumferential", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0039] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0040] In the description of this utility model, it should be noted that terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0041] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0042] In related technologies, the installation of fan components requires assembling the motor, connecting the motor to the fan blades to form the fan, and then mounting the fan on the fan bracket; the assembly process is cumbersome and affects production efficiency. If it is necessary to fix the fan component and the condenser, the fan bracket and the condenser bracket with the condenser installed must be fixedly connected, which not only increases the assembly process but also makes the connection unreliable.

[0043] Reference Figures 1 to 3 As shown, the fan assembly provided in the embodiment of this utility model includes a fan 100 and a bracket 200. The fan 100 includes an inner stator 110, an outer rotor 120, and fan blades 130. The outer rotor 120 is sleeved on the outside of the inner stator 110 and connected to the fan blades 130. The bracket 200 has an air duct 230. The bracket 200 is provided with a mounting part 210 for fixing the condenser 300 and a connecting frame 220 for fixing the inner stator 110. The connecting frame 220 is arranged opposite to the air duct 230, and the mounting part 210 and the connecting frame 220 are arranged along the axial direction of the air duct 230. The bracket 200, the mounting part 210, and the connecting frame 220 are integrally formed.

[0044] The inner stator 110 is mounted on the connecting frame 220 of the bracket 200, and the outer rotor 120 is sleeved on the outside of the inner stator 110 and connected to the fan blade 130. The various parts of the fan 100 are mounted on the bracket 200, reducing the installation process of the fan assembly and improving assembly efficiency. The mounting part 210 of the bracket 200 is used to fix the condenser 300. The fan 100 and the condenser 300 are mounted on the same bracket 200. The bracket 200, the mounting part 210 and the connecting frame 220 are integrally formed, which can reduce the number of parts to be assembled and improve the integration of the fan assembly. Mounting the fan 100 and the condenser 300 on the same bracket 200 is beneficial to keeping the relative positions of the fan 100 and the condenser 300 unchanged. The mounting part 210 and the connecting frame 220 are arranged along the axial direction of the air duct 230. Driven by the fan 100, the airflow flows in the air duct 230, so that the airflow blows towards the condenser 300 to remove the heat from the condenser 300.

[0045] In related technologies, the assembly of fan components requires the stator and rotor to be installed in a motor housing to form a motor, and then the motor to be installed on a bracket 200, with the fan blades 130 connected to the output shaft of the motor. In this embodiment, the various parts of the fan 100 are installed on the bracket 200, reducing the assembly process and thus reducing labor costs. In addition, the outer rotor 120 and inner stator 110 are directly installed on the bracket 200, eliminating the need for the motor housing to fix the outer rotor 120 and inner stator 110, reducing the number of parts in the fan assembly, lowering production costs, and simultaneously increasing the integration of the fan assembly.

[0046] By fixing the fan 100 and condenser 300 with a bracket 200, the relative positions of the fan 100 and condenser 300 remain unchanged, while reducing the number of connecting parts and improving the reliability of the connection between the entire fan assembly and the condenser 300. Since the fan 100 is prone to shaking during operation, directly mounting the inner stator 110 onto the bracket 200 increases the strength of the connection between the fan 100 and the bracket 200, minimizing the shaking of the entire fan assembly during operation. This embodiment of the invention improves the integration of the entire fan assembly by integrating the fan 100 onto the bracket 200 and mounting the condenser 300 on the same bracket 200, reducing assembly steps, increasing assembly efficiency, and thus reducing labor costs.

[0047] Reference Figure 2 As shown, the connecting frame 220 and the air duct 230 are arranged opposite to each other. The inner stator 110 is installed on the connecting frame 220. The inner stator 110 drives the outer rotor 120 to rotate, causing the fan blades 130 to rotate accordingly, thereby driving the airflow to flow in the air duct 230. The air outlet side of the fan 100 can face the condenser 300, so that the airflow in the air duct 230 blows towards the condenser 300. The air outlet side of the fan 100 can also face away from the condenser 300, so that the airflow enters the air duct 230 through the condenser 300. This embodiment of the utility model does not limit this, as long as the fan 100 can drive the airflow through the condenser 300.

[0048] Please refer to Figure 3 In some embodiments, the fan assembly further includes a connecting shaft 500. The fan blade 130 is rotatably connected to the connecting frame 220 via the connecting shaft 500. The connecting frame 220 can support the fan blade 130, improving the stability of the fan blade 130's rotation relative to the support 200. Alternatively, one end of the connecting shaft 500 can be fixed to the fan blade 130, and the other end rotatably connected to the connecting frame 220; or one end can be fixed to the connecting frame 220, and the other end rotatably connected to the fan blade 130. This embodiment of the invention does not particularly limit this approach. Bearings can be installed on the connecting frame 220, and the connecting shaft 500 can be installed within the bearings, making the rotation of the fan blade 130 smoother.

[0049] Please refer to Figure 3 and Figure 7In some embodiments, the inner stator 110 is provided with an opening 111, through which the connecting shaft 500 passes. The opening 111 restricts the radial displacement of the connecting shaft 500, making the rotation of the fan blade 130 more stable. The opening 111 also ensures the coaxiality of the inner stator 110 and the outer rotor 120, which is beneficial to the stable operation of the fan 100. In other embodiments, the fan blade 130 can also be directly rotatably connected to the inner stator 110 via the connecting shaft 500, as long as the fan blade 130 can rotate relative to the bracket 200. This embodiment of the present invention does not impose any particular limitation on this.

[0050] Please refer to Figures 3 to 4 In some embodiments, the fan blade 130 includes a hub 131 and blades 132. The blades 132 are connected to the periphery of the hub 131, and the hub 131 supports the blades 132. A receiving groove 131a is provided on the hub 131, and the outer rotor 120 is embedded in the receiving groove 131a. The inner stator 110 is at least partially located in the receiving groove 131a. The receiving groove 131a acts as a physical barrier for the outer rotor 120 and the inner stator 110, minimizing the impact of external dust and other impurities on the operation of the outer rotor 120 and the inner stator 110. The receiving groove 131a can be a circular groove. The outer rotor 120 is embedded in the receiving groove 131a and fits against the inside of the receiving groove 131a. The inner stator 110 is arranged along the axial direction of the receiving groove 131a, which helps to improve the coaxiality of the inner stator 110 and the outer rotor 120, making the operation of the fan 100 more stable. The inner stator 110 can be connected to the connecting frame 220 by a snap-fit ​​mechanism for easy assembly; the outer rotor 120 is an iron ring, which can be pressed into the receiving groove 131a; the fan 100 may include a magnetic ring 140, which can be pressed into the outer rotor 120. The blades 132 and the hub 131 can be integrally molded by injection molding.

[0051] Please refer to Figures 3 to 4 In some embodiments, the receiving groove 131a is disposed on the side of the hub 131 facing the connecting frame 220, so that the connecting frame 220 can cover at least a portion of the opening of the receiving groove 131a, so that the inner stator 110 and the outer rotor 120 can be integrated inside the fan blade 130, reducing the risk of the inner stator 110 and the outer rotor 120 being exposed, and facilitating the maintenance of the fan 100; in addition, the above arrangement can install the inner stator 110 and the outer rotor 120 without the need for a motor housing, reducing the number of parts in the fan assembly and improving the integration of the fan assembly.

[0052] Please refer to Figure 4In one embodiment, the hub 131 includes a base plate 131b, a connecting rib 131c, an inner cylinder 131d, and an outer cylinder 131e; the inner cylinder 131d and the outer cylinder 131e are connected to the same side of the base plate 131b, the outer cylinder 131e is fitted over the outer side of the inner cylinder 131d, and a hollow gap 131f is formed between the outer cylinder 131e and the inner cylinder 131d, and a receiving groove 131a is formed inside the inner cylinder 131d; the connecting rib 131c is located in the hollow gap 131f. Within 31f, one end of the connecting rib 131c is connected to the inner cylinder 131d, and the other end is connected to the outer cylinder 131e. Multiple connecting ribs 131c are provided to enhance the strength of the connection between the inner cylinder 131d and the outer cylinder 131e. A hollow gap 131f is provided between the inner cylinder 131d and the outer cylinder 131e, which not only reduces the weight of the hub 131 and the amount of material used, but also improves the structural strength of the hub 131 and helps to distribute stress. Multiple reinforcing ribs can be provided inside the inner cylinder 131d, which further enhances the structural strength of the hub 131.

[0053] Please refer to Figure 4 and Figure 5 In some embodiments, the connecting frame 220 has a body portion 221 and a connecting strip 222 connected to each other. The connecting strip 222 is connected to the bracket 200, so that the body portion 221 is fixed to the bracket 200. Along the axial direction of the air duct 230, the cross-section of the body portion 221 is greater than or equal to the opening of the receiving groove 131a, so that the body portion 221 can cover the opening of the receiving groove 131a to prevent external impurities from entering the interior of the receiving groove 131a. The body portion 221 is generally circular. Multiple connecting strips 222 are provided. The connecting strips 222 surround the periphery of the body portion 221 and are connected to the bracket 200. One of the connecting strips 222 is provided with a wire routing buckle 222a, which is used to guide the wires of the inner stator 110 and prevent the wires from being entangled by the blades 132.

[0054] Please refer to Figure 3 and Figure 6 In some embodiments, the mounting portion 210 includes a surrounding plate, which forms a mounting groove 213 along the circumference of the air duct 230. The mounting groove 213 is used to accommodate at least a portion of the condenser 300. The surrounding plate provides a certain degree of protection for the condenser 300, reducing direct damage to the condenser 300 from external forces. At least one surrounding plate abuts against the condenser 300 to limit its position. The condenser 300 may be entirely located in the mounting groove 213, or only partially located within it; this embodiment of the present invention does not impose any particular limitation on this.

[0055] Please refer to Figure 6In some embodiments, the mounting portion 210 is provided with a first clamping arm 240 and a second clamping arm 250, which are spaced apart along the axial direction of the air duct 230; a clamping position 260 for the condenser 300 is formed between the first clamping arm 240 and the second clamping arm 250.

[0056] Understandably, by clamping the condenser 300 with the first clamping arm 240 and the second clamping arm 250, at least a portion of the condenser 300 is fixed to the clamping position 260 between the first clamping arm 240 and the second clamping arm 250, thereby fixing the condenser 300 to the mounting part 210. Supporting the condenser 300 through clamping eliminates the need for drilling or machining on the condenser 300, allowing for simple and convenient installation with high efficiency. Simultaneously, it reduces damage to the surface of the condenser 300, maintaining its overall appearance. The condenser 300 can be entirely or partially located in the clamping position 260, as long as the first clamping arm 240 and the second clamping arm 250 can secure the condenser 300.

[0057] The first clamping arm 240 and the second clamping arm 250 are arranged along the axial direction of the air duct 230. The first clamping arm 240 is closer to the fan 100 than the second clamping arm 250, such that the first clamping arm 240 is located on the side of the clamped portion of the condenser 300 closer to the fan 100, and the second clamping arm 250 is located on the side of the clamped portion of the condenser 300 away from the fan 100, thereby restricting the axial displacement of the condenser 300 in the air duct 230. In other words, the first clamping arm 240 is located at the end of the mounting portion 210 closer to the fan 100 and extends from the mounting portion 210 toward the condenser 300 to restrict the movement of the condenser 300 toward the fan 100.

[0058] Please refer to Figure 1 and Figure 6 In some embodiments, the condenser 300 includes multiple refrigerant pipes 310. The first clamping arm 240 has a fastening groove 241, in which one refrigerant pipe 310 is engaged. The fastening groove 241 supports the refrigerant pipes 310 of the condenser 300, thereby fixing the condenser 300. The condenser 300 has a housing 320 and refrigerant pipes 310. If the first clamping arm 240 directly abuts against the surface of the housing 320, the condenser 300 is prone to sliding relative to the support 200 due to the relatively flat surface of the housing 320, which is not conducive to fixing the condenser 300. Since the diameter of the refrigerant pipes 310 is relatively small, fixing one of the refrigerant pipes 310 through the fastening groove 241, so that the refrigerant pipe 310 is embedded in the fastening groove 241, can limit the displacement of the refrigerant pipe 310, thereby minimizing the displacement of the condenser 300 relative to the support 200 and improving the fixing effect.

[0059] Generally, the condenser 300 includes multiple refrigerant pipes 310, which are arranged along the thickness direction of the condenser 300 (i.e., the axial direction of the air duct 230) and are connected to each other. The refrigerant pipes 310 include multiple vertically arranged straight pipes 312 and bends 311 connecting two adjacent straight pipes 312. The straight pipes 312 are generally arranged horizontally, and the locking groove 241 can lock the straight pipes 312, so that the straight pipes 312 cannot be displaced in the vertical direction, thereby restricting the movement of the condenser 300 in the vertical direction.

[0060] Please refer to Figure 1 and Figure 6 In some embodiments, the second clamping arm 250 is provided with a limiting protrusion 251, and a limiting surface 251a is provided on the side of the limiting protrusion 251 facing the fan 100. The limiting surface 251a abuts against the refrigerant pipe 310 of the condenser 300, thereby restricting the condenser 300 from moving away from the fan 100. The limiting surface 251a is generally a plane. The planar limiting surface 251a is simple to process and can simultaneously abut against both the straight pipe 312 and the bent pipe 311 of the refrigerant pipe 310. When the second clamping arm 250 limits the refrigerant pipe 310, it can abut against any part of the refrigerant pipe 310 without precise positioning, reducing assembly difficulty. Of course, in other embodiments, the limiting surface 251a can also be an arc surface that fits the refrigerant pipe 310. This embodiment of the present invention does not particularly limit this.

[0061] In this embodiment of the invention, the first clamping arm 240 uses the fastening groove 241 to limit one of the refrigerant pipes 310, and then the second clamping arm 250 limits the refrigerant pipe 310, so that part of the condenser 300 is located on the clamping position 260, thereby fixing the condenser 300. For example, the condenser 300 includes a first refrigerant pipe 313 and a second refrigerant pipe 314. The first refrigerant pipe 313 is closer to the fan 100 than the second refrigerant pipe 314. One of the straight pipes 312 of the first refrigerant pipe 313 is embedded in the snap-fit ​​groove 241 of the first clamping arm 240. The second refrigerant pipe 314 abuts against the limiting surface 251a, thereby limiting the displacement of the condenser 300. The first refrigerant pipe 313 can be the refrigerant pipe 310 closest to the fan 100 so that the first clamping arm 240 can fix the first refrigerant pipe 313. The first refrigerant pipe 313 and the second refrigerant pipe 314 can be two adjacent refrigerant pipes 310 to reduce the number of the first clamping arms 240. The distance between the first clamping arm 240 and the second clamping arm 250 is such that, when the condenser 300 is small in size and thin, the number of refrigerant pipes 310 in the condenser 300 is reduced accordingly. The smaller distance between the first clamping arm 240 and the second clamping arm 250, and their proximity to the fan 100, allows the first clamping arm 240 and the second clamping arm 250 to accommodate smaller refrigerant pipes 310. Conversely, if the condenser 300 is large in size and thick, the number of refrigerant pipes 310 increases accordingly, and the first clamping arm 240 and the second clamping arm 250 can still secure the condenser 300. Therefore, this embodiment of the invention, by supporting the refrigerant pipes 310 of the condenser 300 with the first clamping arm 240 and the second clamping arm 250, can accommodate condensers 300 of different sizes.

[0062] Of course, in other embodiments, other refrigerant pipes 310 may be provided between the first refrigerant pipe 313 and the second refrigerant pipe 314; or, the first refrigerant pipe 313 and the second refrigerant pipe 314 may be the same refrigerant pipe 310, and the same refrigerant pipe 310 may be fixed by the first clamping arm 240 and the second clamping arm 250, thereby fixing the condenser 300. This utility model embodiment does not limit this.

[0063] Please refer to Figure 1 and Figure 6In some embodiments, the limiting protrusion 251 is provided with a guide surface 251b, which guides the refrigerant pipe 310 of the condenser 300 to the limiting surface 251a. Guiding the refrigerant pipe 310 to the limiting surface 251a via the guide surface 251b facilitates the installation of the condenser 300 and reduces assembly difficulty. The guide surface 251b can be a sloped surface or an arc surface. The limiting protrusion 251 can be a hollow design to reduce its weight; a hollow groove can be provided on the guide surface 251b to reduce the material used in the limiting protrusion 251.

[0064] Please refer to Figure 3 and Figure 6 In some embodiments, the enclosure includes a first enclosure 211a and a second enclosure 211c disposed opposite to each other. The first enclosure 211a abuts against the condenser 300 to further limit the condenser 300. The first enclosure 211a has at least two notches 211b extending along the axial direction of the air duct 230. When disassembling or assembling the condenser 300, the first enclosure 211a can be pried open, causing a portion of the first enclosure 211a to bend along the axial direction of the air duct 230 toward the outside of the mounting groove 213. A larger space is created between the first enclosure 21a and the second enclosure 211c to facilitate the installation of the condenser 300 into the mounting slot 213 or the removal of the condenser 300 from the mounting slot 213. During installation, the condenser 300 is placed into the mounting slot 213 by bending the first enclosure 211a. The refrigerant pipe 310 of the condenser 300 can then be fixed by the first clamping arm 240 and the second clamping arm 250. The first enclosure 211a is then released, allowing it to return to its original position and abut against the condenser 300, thus fixing the condenser 300 in place. The first enclosure plate 211a may have two notches 211b, the distance between the two notches 211b being less than the width of the housing 320 of the condenser 300, so that the first enclosure plate 211a restricts the displacement of the housing 320 of the condenser 300; the distance between the other notches 211b may be approximately equal to the width of the housing 320 of the condenser 300, which is beneficial to bend the part of the first enclosure plate 211a located between the two notches 211b, so that the condenser 300 has enough space to enter the mounting groove 213.

[0065] Please refer to Figure 3 and Figure 6In some embodiments, along the direction from the first enclosure 211a to the second enclosure 211c, the length of the condenser 300 is less than the distance between the first enclosure 211a and the second enclosure 211c, reducing the difficulty of fixing the condenser 300 between the first enclosure 211a and the second enclosure 211c. After the condenser 300 is fixed by the first clamping arm 240 and the second clamping arm 250, the large distance between the first enclosure 211a and the second enclosure 211c creates an installation gap 211f between the condenser 300 and the second enclosure 211c. When removing the condenser 300, there is sufficient space below the condenser 300 to adjust its position, which facilitates the removal of the condenser 300 from the bracket 200.

[0066] The first frame 211 also includes a third enclosure 211d and a fourth enclosure 211e, which are opposite to each other. The first enclosure 211a is located above the second enclosure 211c, that is, the first enclosure 211a is located at the top of the mounting part 210, and the second enclosure 211c is located at the bottom of the mounting part 210. The third enclosure 211d connects one end of the first enclosure 211a and the second enclosure 211c, and the fourth enclosure 211e connects the other end of the first enclosure 211a and the second enclosure 211c. Two second clamping arms 250 are provided. One second clamping arm 250 is connected to the third enclosure 211d and extends along the axial direction of the air duct 230, and the other second clamping arm 250 is connected to the fourth enclosure 211e and extends along the axial direction of the air duct 230. The limiting protrusion 251 of the second clamping arm 250 is provided on the side facing the condenser 300 to limit the condenser 300 by means of the limiting protrusion 251.

[0067] Please refer to Figure 3 and Figure 6The mounting section 210 includes a first frame 211 and a second frame 212, which are arranged along the axial direction of the air duct 230. A surrounding plate is arranged along the circumference of the condenser 300 to form the first frame 211, and a mounting groove 213 is formed within the first frame 211. In the event of damage to the first clamping arm 240 or the second clamping arm 250, the surrounding plate can prevent the condenser 300 from sliding out of the mounting groove 213, reducing the probability of damage to the condenser 300. The first frame 211 is used to accommodate at least a portion of the fan 100 to reduce the exposure of the fan 100 and prevent operators from accidentally contacting the blades 132 of the fan blades 130, reducing the risk of injury. The overall size of the fan assembly is smaller than that of the condenser 300. Along the axial direction of the air duct 230, the cross-section of the first frame 211 is smaller than that of the second frame 212 to minimize the overall volume of the fan assembly. The first frame 211 and the second frame 212 can be connected by an inclined plate, which is beneficial for processing the mounting part 210. For example, the mounting part 210 can be integrally molded by injection molding to reduce the processing steps. There are two first clamping arms 240. The first clamping arms 240 are located inside the first frame 211 and connected to the two side walls of the first frame 211 that are opposite to each other. The first clamping arms 240 extend along the axial direction of the air duct 230 to engage the refrigerant pipe 310 of the condenser 300.

[0068] Please refer to Figure 1 and Figure 6 The inner wall of the first frame 211 may be provided with a stop 214. The side of the stop 214 away from the fan 100 forms a stop wall 214a. The stop wall 214a is used to abut against the condenser 300 to further limit the condenser 300.

[0069] Please refer to Figure 1 In some embodiments, the fan assembly also includes a water receiving tray 400, a bracket 200 fixed to the water receiving tray 400, a fan 100 and a condenser 300 located on the water receiving tray 400, and a baffle wall 270 provided around the periphery of the second enclosure 211c. The baffle wall 270 is used to isolate the condenser 300 from the water in the water receiving tray 400, reducing the risk of the condenser 300 being immersed in the water in the water receiving tray 400. In addition, the baffle wall 270 protects the condenser 300. If the first clamping arm 240 or the second clamping arm 250 breaks, the baffle wall 270 can prevent the condenser 300 from sliding directly into the water receiving tray 400, reducing unnecessary losses.
