[0049] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0050] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to refrigerate or heat an indoor space.

[0051] The low-temperature and low-pressure refrigerant enters the compressor, which compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0052] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with a material to be cooled using latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of an indoor space.

[0053] The outdoor unit of the air conditioner refers to a portion of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0054] The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in a heating mode, and when the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in a cooling mode.

[0055] Embodiment one, as Figures 1-7 shown, an air conditioner indoor unit is provided in an embodiment of the present application, comprising:

[0056] A shell 1 is provided with an air inlet 11 and an air outlet 12;

[0057] A heat exchanger 2 is used to exchange heat with the airflow passing through to form a heat exchange airflow;

[0058] A fan assembly 3 includes a motor 31, a fan 32, a first mounting member 33, and a second mounting member 34. The first mounting member 33 is provided with a first fixing bracket 331 and a first half cavity 332, and the second mounting member 34 is provided with a second fixing bracket 341 and a second half cavity 342. The fan 32 is arranged on the rotating shaft of the motor 31, the first mounting member 33 is arranged on the second mounting member 34, the motor 31 is arranged between the first fixing bracket 331 and the second fixing bracket 341, and the fan 32 is located in the volute formed between the first half cavity 332 and the second half cavity 342;

[0059] Among them, the heat exchanger 2 and the fan assembly 3 are arranged in the shell 1 respectively; the fan assembly 3 is configured to introduce the airflow outside the shell 1 from the air inlet 11 to the inside of the shell 1 and exchange heat via the heat exchanger 2 and output outwardly from the air outlet 12.

[0060] Specifically, the fan assembly 3 meets the installation requirements of the motor 31 and the fan 32 by respectively integrating the fixing bracket and the half cavity on the first mounting member 33 and the second mounting member 34.

[0061] The first fixing frame 331 arranged on the first mounting member 33 and the second fixing frame 341 arranged on the second mounting member 34 are matched with each other to fix and install the motor 31.

[0062] The motor 31 is placed between the first fixing frame 331 and the second fixing frame 341, and the first fixing frame 331 and the second fixing frame 341 are connected together to firmly fix the motor 31 between the first fixing frame 331 and the second fixing frame 341.

[0063] In this way, the motor 31 can be fixed and installed by means of the two mounting members without separately configuring a motor support for the motor 31, thereby simplifying the overall structure of the fan assembly 3.

[0064] Similarly, for the fan 32, the first half cavity 332 arranged on the first mounting member 33 and the second half cavity 342 arranged on the second mounting member 34 are matched with each other to form a volute to meet the installation requirements of the fan 32 for driving airflow.

[0065] The fan 32 is assembled to the rotating shaft of the motor 31, and the fan 32 is located between the first half cavity 332 and the second half cavity 342 after the first mounting member 33 and the second mounting member 34 are connected and fixed, so that the first half cavity 332 and the second half cavity 342 wrap the fan 32, and the fan 32 is located in the volute.

[0066] After the fan assembly 3 is assembled, it can be assembled into the shell 1 as a whole, thereby eliminating the need to install the motor 31, the fan 32, and the volute and other components one by one on the bottom of the shell 1.

[0067] The motor is installed by means of the fixing frames formed on the first mounting member and the second mounting member. In the actual assembly process, after the fan and the motor are assembled together, the fan and the motor can be assembled between the first mounting member and the second mounting member, and the half cavities of the two mounting members are assembled together to form a volute, so that the fan is located in the volute, and for the motor, the first fixing frame and the second fixing frame are used for fixed installation, thereby eliminating the need to additionally increase a motor support for independent assembly. On the one hand, the number of parts of the fan assembly can be effectively reduced, and on the other hand, the overall assembly process of the air conditioner indoor unit can be further simplified, and the assembly efficiency and assembly quality are improved.

[0068] In another embodiment of the present application, in order to improve the assembly reliability of the motor 31, a first arc-shaped groove 3311 is arranged on the first fixing frame 331, and a second arc-shaped groove 3411 is arranged on the second fixing frame 341; the motor 31 is located between the first arc-shaped groove 3311 and the second arc-shaped groove 3411.

[0069] Specifically, the first arc-shaped groove 3311 and the second arc-shaped groove 3411 can match the external profile of the motor 31, so that the motor 31 can be more stably and reliably installed and fixed.

[0070] In some embodiments, the motor 31 is respectively provided with a limiting ring 311 at both ends, the first arc-shaped groove 3311 is provided with a first limiting groove at both ends, and the second arc-shaped groove 3411 is provided with a second limiting groove 3412 at both ends.

[0071] Specifically, during assembly, the motor 31 can be pre-assembled by being placed in the second arc-shaped groove 3411, and after the motor 31 is placed in the second arc-shaped groove 3411, the limiting ring 311 at the end of the motor 31 will be clamped in the corresponding second limiting groove, thereby limiting the movement of the motor 31 along its axis direction. Then, the first mounting member 33 is fixed on the second mounting member 34, so that the second arc-shaped groove 3411 is above the motor 31, and the limiting ring 311 at the end of the motor 31 is clamped in the corresponding first limiting groove.

[0072] In some embodiments, in order to facilitate the assembly of the first mounting member 33 and the second mounting member 34, the first mounting member 33 is provided with a clamping portion 333 outside the first half cavity 332, and the second mounting member 34 is provided with a clamping matching portion 343 outside the second half cavity 342, and the clamping portion 333 and the clamping matching portion 343 are clamped together.

[0073] Specifically, in order to reduce the amount of screws used and simplify the assembly process of the first mounting member 33 and the second mounting member 34, the first mounting member 33 and the second mounting member 34 can be pre-assembled by clamping.

[0074] In actual use, the clamping portion 333 and the clamping matching portion 343 can have various structural matching forms, such as clamping jaws and clamping grooves, or using a clasp structure, which is not limited and described here.

[0075] In another embodiment, in order to ensure that the first mounting member 33 and the second mounting member 34 are firmly fixed and play a role in firmly and reliably installing the motor 31, the first fixing frame 331 and the second fixing frame 341 are fixedly connected together by screws.

[0076] Specifically, for the motor 31, the first fixing frame 331 and the second fixing frame 341 are fixedly installed, and the first fixing frame 331 and the second fixing frame 341 can be fastened by a plurality of screws, thereby improving the connection reliability between the first fixing frame 331 and the second fixing frame 341, on the one hand, meeting the requirement of firm connection between the first mounting part 33 and the second mounting part 34, and on the other hand, meeting the requirement of reliable installation of the motor 31.

[0077] In some embodiments of the application, the two sides of the first arc-shaped groove 3311 are respectively provided with first edge covering structures (not marked), which abut against the corresponding end faces of the motor 31.

[0078] Specifically, the first edge covering structure is fixed and limited from the outer end face of the motor 31, which can better fix the motor 31.

[0079] Similarly, in another embodiment, a second edge covering structure can also be arranged on the two sides of the second arc-shaped groove 3411, and the second edge covering structure abuts against the corresponding end face of the motor 31.

[0080] In another embodiment of the application, the second fixing frame 341 includes two support plates 3413, the two support plates 3413 are vertically arranged opposite to each other, the support plate 3413 is respectively provided with a second arc-shaped groove 3411, and the support plate 3413 is further provided with a ventilation hole 3414, and the support plate 3413 and the corresponding side of the cochlea form a ventilation interval.

[0081] Specifically, for the second fixing frame 341, as a component for bearing and installing the motor 31, the two support plates 3413 arranged side by side are used to support the two ends of the motor 31 respectively, so as to improve the installation reliability of the motor 31.

[0082] The ventilation hole 3414 arranged on the two support plates 3413 has an area accounting for 60%-70% of the area of the support plate 3413, so as to effectively increase the air flow on the side of the motor 31 and be more conducive to reducing the wind resistance. The cochlea and the support plate 3413 form an air inlet area to ensure the air inlet requirement of the fan 32.

[0083] In another embodiment of the application, the surface of the first mounting part 33 away from the first arc-shaped groove 3311 is provided with a plurality of first ribs 334 arranged side by side, and the surface of the first mounting part 33 away from the first arc-shaped groove 3311 is further provided with a second rib 335, the second rib 335 crosses each first rib 334 and is arranged staggered with the first rib 334.

[0084] Specifically, the left and right sides of the first mounting component 33 form an arc-shaped bridge structure, and the two arc-shaped bridge structures are connected and fixed together by multiple first ribs 334. At the same time, the multiple first ribs 334 are further connected together by second ribs 335. While strengthening the overall strength of the first mounting component 33, it can also effectively reduce the amount of material used and achieve product lightweighting.

[0085] Furthermore, a guide groove is formed between adjacent ribs, and the guide groove is divided into two air guide sections distributed to the left and right by the second rib 335. The air guide sections are configured to guide the airflow towards the volute cavity on the corresponding side. During use, the airflow above the motor 31 can be guided through the air guide sections on both sides of the second rib 335, which is more conducive to increasing the air intake of the fan 32.

[0086] In addition, for the fan assembly 3, in order to facilitate its installation in the housing 1, at least the installation methods provided in the following two embodiments can be adopted, which will be described below in conjunction with the accompanying drawings.

[0087] Example 2, as Figures 3-8 As shown, for the fan assembly 3, a partition 13 is additionally configured in the housing 1. A vent 100 is provided on the partition 13. The partition 13 is arranged vertically and located between the fan assembly 3 and the heat exchanger 2. The vent 100 is connected to the exhaust port 302. A first mounting member 33 and / or a second mounting member 34 are provided on the partition 13.

[0088] Specifically, the partition 13 divides the outer shell 1 into an air inlet cavity and a heat exchange cavity. The air drawn in from the air inlet 11 first enters the air inlet cavity and is then transported from the vent 100 to the heat exchange cavity via the fan assembly 3. The airflow will exchange heat with the heat exchanger 2 in the heat exchange cavity, and the heat-exchanged airflow will be output to the outside of the outer shell 1 from the air outlet 12.

[0089] In the actual assembly process, after the fan assembly 3 is assembled, it can be mounted onto the partition 13 provided in the outer casing 1. Depending on the installation requirements, the first mounting part 33 or the second mounting part 34 can be used as the component to be fixedly connected to the partition 13, thereby completing the fixed installation of the fan assembly 3 onto the partition 13.

[0090] In some embodiments of this application, taking the second mounting member 34 fixedly mounted on the partition plate 13 as an example, the side surface of the second mounting member 34 can be fixedly mounted on the partition plate 13 by screws to complete the fixed mounting of the fan assembly 3 on the partition plate 13.

[0091] The side of the second mounting member 34 is provided with a vertical extension 344, and when the fan assembly 3 is mounted on the partition plate 13, a mounting hole can be arranged on the vertical extension 344, and a screw is fixed on the partition plate 13 through the mounting hole, so that the fan assembly 3 is fixed on the partition plate 13 through the second mounting member 34.

[0092] When the fan assembly 3 is modularly assembled, a positioning clamping groove 336 can be arranged on the first mounting member 33 correspondingly, and the vertical extension 344 is arranged in the positioning clamping groove 336.

[0093] Specifically, in the actual assembly process of the fan assembly 3, the first mounting member 33 needs to be mounted above the second mounting member 34, and in the process of assembling the first mounting member 33 to the second mounting member 34, the vertical extension 344 will correspondingly extend into the positioning clamping groove 336.

[0094] The vertical extension 344 cooperates with the positioning clamping groove 336, on the one hand, the vertical extension 344 guides the first mounting member 33 to be accurately assembled to the second mounting member 34, and on the other hand, the installation contact area between the first mounting member 33 and the second mounting member 34 is increased, so that the first mounting member 33 and the second mounting member 34 are more firmly and reliably fixed and connected together.

[0095] In some embodiments of the application, the two sides of the first mounting member 33 are respectively provided with first half cavities 332, and the two ends of the first half cavities 332 respectively form first air inlet notches (not marked), and one side of the first half cavities 332 is provided with a first air outlet notch (not marked);

[0096] The two sides of the second mounting member 34 are respectively provided with second half cavities 342, and the two ends of the second half cavities 342 form second air inlet notches (not marked), and one side of the second half cavities 342 is provided with a second air outlet notch (not marked);

[0097] The first air inlet notch and the corresponding second air inlet notch are buckled together to form an air suction port 301, the first air outlet notch and the corresponding second air outlet notch are buckled together to form an air exhaust port 302, and the air suction port 301 and the air exhaust port 302 are respectively communicated with the cochlea.

[0098] Specifically, the first mounting member 33 is provided with the first half cavities 332 on the two sides of the first fixing frame 331, and correspondingly, the second mounting member 34 is provided with the second half cavities 342 on the two sides of the second fixing frame 341. In this way, the motor 31 adopts a double-shaft mode, the two sides of the motor 31 are respectively provided with the fans 32, and the corresponding side fans 32 are assembled between the corresponding side first half cavities 332 and second half cavities 342.

[0099] To meet the requirements for air intake and exhaust, the first half-cavity 332 has a first air intake notch at both ends, and correspondingly, the second half-cavity 342 has a second air intake notch at both ends. The first and second air intake notches can be semi-circular arc-shaped. After the first mounting component 33 and the second mounting component 34 are assembled together, the first air intake notch and the corresponding second air intake notch are assembled together to form an air intake 301, thereby forming air intakes 301 at both ends of the fan 32 to meet the requirements for large air volume intake.

[0100] Similarly, to meet the air outlet requirements, a first air outlet notch is formed on the side of the first half-cavity 332, and correspondingly, a second air outlet notch is formed on the side of the second half-cavity 342. The first and second air outlet notches can be rectangular notch structures. After the first mounting member 33 and the second mounting member 34 are assembled together, the first air outlet notch and the corresponding second air outlet notch are assembled together to form an air outlet 12, thereby enabling the airflow generated on one side of the fan 32 to be output from the air outlet 12 to the heat exchange cavity.

[0101] In some embodiments, in order to improve the overall structural strength of the second mounting member 34, a plurality of U-shaped reinforcing ribs 345 are provided between the two support plates 3413 and the vertical extension 344. The plurality of U-shaped reinforcing ribs 345 are arranged sequentially from top to bottom and are arranged laterally.

[0102] Specifically, an additional U-shaped reinforcing rib 345 is added at the position of the second fixing frame 341. The U-shaped reinforcing rib 345 can further connect and fix the two support plates 3413 forming the second fixing frame 341 to the vertical extension 344, so as to improve the structural strength between the support plates 3413 and the vertical extension 344, thereby meeting the fixed installation requirements of the motor 31.

[0103] In addition, several staggered structural reinforcing ribs can be further provided on the outer surface of the support plate 3413 to improve the structural strength while reducing the thickness of the support plate 3413, thereby increasing the overall strength of the fixed motor while reducing the amount of material used.

[0104] Example 3, as Figures 9-11 As shown, for the fan assembly 3, there is no need to configure an additional partition in the outer casing 1 to install the fan assembly 3. Instead, the fan assembly 3 itself forms a structure to replace the partition for installation. The specific details are explained below with reference to the attached drawings.

[0105] A partition 346 is provided on one side of the second mounting component 34. The partition 346 extends laterally and is arranged vertically in the outer shell 1. The partition 346 divides the outer shell 1 into an air inlet cavity and a heat exchange cavity. The air inlet 11 is connected to the air inlet cavity, and the air outlet 12 is connected to the heat exchange cavity.

[0106] The interval part 346 is provided with a ventilation opening 100, which communicates with the cochlea. The airflow drawn into the air inlet cavity by the fan 32 driven by the motor 31 enters the heat exchange cavity from the ventilation opening 100.

[0107] Specifically, the second mounting member 34 is formed with an integral interval part 346 extending along the width direction of the shell 1. Thus, after the fan assembly is assembled into the shell 1, the internal space of the shell 1 is divided into an air inlet cavity and a heat exchange cavity by the interval part 346.

[0108] Since the fan assembly 3 itself is integrated with the interval part 346 through the second mounting member 34, the step of separately installing a partition plate in the shell 1 can be saved in the actual assembly process. Since the interval part 346 is integrated on the second mounting member 34, the assembly step of the fan assembly 3 and the partition plate is further saved.

[0109] In the actual assembly process, after the motor 31 and the fan 32 are installed on the first mounting member 33 and the second mounting member 34, the fan assembly 3 is assembled into the shell 1 as a whole. In the assembly process, an inverted installation method is usually adopted, i.e., the top plate of the shell 1 is placed on the installation platform first. At this time, the fan assembly 3 is placed on the top plate as a whole, and the interval part 346 is fixedly connected with the top plate of the shell 1 through screws. Then, the two side plates and the bottom plate of the shell 1 are fixedly connected with the interval part 346 through screws, thereby realizing the assembly of the fan assembly 3 into the shell 1.

[0110] After the fan assembly 3 is assembled onto the top plate of the shell 1, the specific assembly process of the heat exchanger 2 can refer to the conventional technology, which is not limited and described herein.

[0111] In another embodiment of the present application, a plurality of U-shaped reinforcing ribs 345 are further arranged between the two support plates 3413 and the interval part 346. The U-shaped reinforcing ribs 345 are arranged in sequence from top to bottom, and the U-shaped reinforcing ribs 345 are arranged transversely.

[0112] Specifically, the U-shaped reinforcing rib 345 is additionally arranged at the position of the second fixing frame 341. The U-shaped reinforcing rib 345 can further connect and fix the two support plates 3413 forming the second fixing frame 341 and the interval part 346, so as to improve the structural strength between the support plates 3413 and the interval part 346, thereby meeting the fixed installation requirements of the motor 31.

[0113] The interval part 346 is also provided with a vertical extension part 344. Correspondingly, the first mounting member 33 is provided with a positioning clamping groove 336, and the vertical extension part 344 is arranged in the positioning clamping groove 336.

[0114] Specifically, during the actual assembly process, the first mounting member 33 needs to be installed above the second mounting member 34, and during the assembly of the first mounting member 33 to the second mounting member 34, the vertical extension 344 will be inserted into the corresponding positioning clamping groove 336.

[0115] Similarly, a plurality of misarranged structural reinforcing ribs can be further arranged on the outer surface of the support plate 3413 to increase the structural strength under the premise of reducing the thickness of the support plate 3413, thereby increasing the overall strength of the fixed motor while reducing the amount of material used.

[0116] In another embodiment of the present application, since the second mounting member 34 is integrated with the spacing portion 346, in order to form the second fixing frame 341 and the second half cavity 342 on the second mounting member 34 in an integrated structure, the arc-shaped extension 347 can be arranged on the second mounting member 34 located at the bottom edge of the air vent 100, the arc-shaped extension 347 extends in a direction away from the air vent 100 and curves upward, and the arc-shaped extension 347 forms the second half cavity 342.

[0117] Specifically, for the second fixing frame 341, two support plates 3413 are used to cooperate to form the second fixing frame 341. For the second half cavities 342 on both sides of the second fixing frame 341, the arc-shaped extension 347 extending away from the air vent 100 can be formed on the spacing portion 346, and the arc-shaped extension 347 can form the second half cavity 342 by relying on its own structure to meet the installation and fixing requirements of the motor 31.

[0118] In another embodiment, the two ends of the first half cavity 332 are respectively provided with a first air inlet gap (not shown), and the two sides of the arc-shaped extension 347 are respectively provided with a side plate 348, and the side plate 348 is provided with a second air inlet gap (not shown); the first air inlet gap and the corresponding second air inlet gap are buckled together to form the air suction port 301, and the lower edge of the first half cavity 332 and the edge of the air vent 100 form the air exhaust port 302.

[0119] In order to meet the air inlet and outlet requirements, the two ends of the first half cavity 332 are provided with a first air inlet gap, and the side plates 348 on both sides of the arc-shaped extension 347 are provided with a second air inlet gap. The first air inlet gap and the second air inlet gap can be semicircular, and after the first mounting member 33 and the second mounting member 34 are assembled together, the first air inlet gap and the corresponding second air inlet gap are assembled together to form the air suction port 301, thereby forming the air suction port 301 at both ends of the fan 32 to meet the requirement of large air volume suction.

[0120] Similarly, in order to meet the air outlet requirements, after the first mounting member 33 and the second mounting member 34 are assembled together, the lower edge of the first half-cavity 332 will form an air outlet 12 with the air vent 100 provided by the partition 346, thereby realizing that the airflow formed on one side of the fan 32 is output from the air outlet 12 to the heat exchange cavity.

[0121] In one embodiment, the second fixing frame 341 and the arc-shaped extension 347 are located on the same side of the partition 346, and the second fixing frame 341 is located between the two arc-shaped extensions 347, thereby meeting the installation requirements of the fan 32 arranged on both sides of the motor 31.

[0122] In some embodiments, in order to facilitate firm connection of the partition 346 with each plate body of the shell 1, the edge of the partition 346 is provided with a flanging structure 349 arranged on the inner wall of the shell 1.

[0123] Specifically, by arranging the flanging structure 349 on the edge of the partition 346, the flanging structure 349 is abutted on the inner wall of the shell 1 to increase the contact area of the partition 346 with the shell 1, and the flanging structure 349 is fastened on the shell 1 by screwing or other fixing modes.

[0124] In some embodiments, in order to facilitate wiring, a wiring hole (not labeled) can also be arranged on the partition 346.

[0125] By arranging the fixing frames on the first mounting member and the second mounting member to mount the motor, in the actual assembly process, after the fan and the motor are assembled together, the fan and the motor can be assembled between the first mounting member and the second mounting member, and the half-cavities of the two mounting members are assembled together to form a volute, so that the fan is located in the volute, and for the motor, the first fixing frame and the second fixing frame are arranged to fix and mount the motor, thereby eliminating the need for additional motor support to be independently assembled, which on the one hand can effectively reduce the parts of the fan assembly, and on the other hand can further simplify the overall assembly process of the air conditioner indoor unit, thereby improving the assembly efficiency and assembly quality.

[0126] In another embodiment of the present application, as shown in Figures 12-15 In order to enable the heat exchanger 2 to uniformly exchange heat with the airflow, the air conditioner indoor unit further comprises a wind guide assembly 4.

[0127] The wind guide assembly 4 comprises a driving component 41, a first wind guide plate 42 and a second wind guide plate 43, the first wind guide plate 42 and the second wind guide plate 43 are arranged in a staggered manner, the first wind guide plate 42 and the second wind guide plate 43 are rotatably arranged on the partition 13 and arranged on the front side of the air vent 100, and the driving component 41 is configured to drive the first wind guide plate 42 and the second wind guide plate 43 to rotate.

[0128] Specifically, in the shell 1, along the conveying direction of the air flow, the heat exchanger 2 is arranged at the front side of the air vent 100, and the fan assembly 3 starts to suck the air from the outside into the shell 1 and conveys it through the air vent 100 towards the heat exchanger 2.

[0129] For the air flow contacting the heat exchanger 2, due to the position and opening area of the air vent 100, the distribution area of the air flow is relatively concentrated, and the heat exchanger 2 is usually arranged obliquely along the conveying direction of the air flow, which can further aggravate the uneven distribution of the air flow on the surface of the heat exchanger 2.

[0130] And by additionally configuring the air guide assembly 4 at the front side of the air vent 100, the first air guide plate 42 and the second air guide plate 43 in the air guide assembly 4 are arranged alternately, which can control the air flow output from the air vent 100 to be adjusted in the up-down and left-right directions.

[0131] In actual use, the first air guide plate 42 and the second air guide plate 43 are driven to rotate by the driving component 41. For the rotating first air guide plate 42, it can be arranged vertically, and in the rotating process, the left-right direction dispersion flow of the air flow is controlled by the first air guide plate 42. For the rotating second air guide plate 43, it can be arranged horizontally, and in the rotating process, the up-down direction dispersion flow of the air flow is controlled by the second air guide plate 43.

[0132] Under the action of the first air guide plate 42 and the second air guide plate 43, the air flow output from the air vent 100 can be uniformly distributed to each area of the heat exchanger 2, so that each part of the heat exchanger 2 can obtain sufficient and uniform heat exchange, and the heat exchange efficiency of the heat exchanger is improved.

[0133] The performance entity of the driving component 41 can adopt a conventional driving device such as a motor, which is not limited and described here.

[0134] By setting the air guide assembly at the air vent on the partition plate, the first air guide plate and the second air guide plate in the air guide assembly are arranged alternately, and the flow direction of the air flow output from the air vent can be adjusted by the first air guide plate and the second air guide plate to adjust the flow path in the left-right and up-down directions, so that the air flow can be uniformly distributed on the heat exchange surface formed by the heat exchanger, and the heat exchange surface of the heat exchanger can be fully utilized to improve the heat exchange efficiency, which can match different specifications of the heat exchanger and the installation position of the heat exchanger, and the versatility of the fan assembly is improved.

[0135] In another embodiment of the present application, the left and right sides of the air vent 100 are respectively provided with the first air guide plate 42 arranged vertically, and the upper and lower ends of the air vent 100 are respectively provided with the second air guide plate 43 arranged horizontally.

[0136] Specifically, in order to conveniently adjust the air flow distribution amount in the left-right direction, first air deflectors 42 are arranged on both sides of the air vent 100, and the two first air deflectors 42 can independently rotate, and for this reason, the first air deflectors 42 can be provided with independent driving components 41.

[0137] In this way, in use, the first air deflectors 42 on both sides respectively control the partial air flow output from the air vent 100 to be distributed and transmitted towards both sides of the air vent 100.

[0138] Similarly, in order to conveniently adjust the air flow distribution amount in the up-down direction, second air deflectors 43 arranged in the up-down direction are arranged on the air vent 100, and the two second air deflectors 43 can independently rotate, and for this reason, the second air deflectors 43 can be provided with independent driving components 41.

[0139] In this way, in use, the second air deflectors 43 arranged in the up-down direction respectively control the partial air flow output from the air vent 100 to be distributed and transmitted upwards and downwards of the air vent 100.

[0140] In another embodiment of the present application, the first air deflectors 42 and the second air deflectors 43 are arc-shaped in a cross section perpendicular to the length direction.

[0141] Specifically, the cross section of the first air deflectors 42 and the second air deflectors 43 is arc-shaped, so that the first air deflectors 42 and the second air deflectors 43 each form an arc-shaped air deflector surface, to more effectively guide and transport the air flow.

[0142] Furthermore, for the arc-shaped air deflector surface, the air deflection angle is larger, to better guide the air flow to cover the edge region of the heat exchanger 2.

[0143] In another embodiment, the convex surfaces of the two first air deflectors 42 are arranged opposite to each other, and the concave surfaces of the two first air deflectors 42 are arranged away from each other; and / or, the convex surfaces of the two second air deflectors 43 are arranged opposite to each other, and the concave surfaces of the two second air deflectors 43 are arranged away from each other.

[0144] Specifically, in order to maximize the air flow coverage area adjusted by the air deflectors, for the first air deflectors 42 arranged opposite to each other, the two first air deflectors 42 are arranged away from each other, and the arc-shaped concave surfaces formed by the first air deflectors 42 are arranged away from each other.

[0145] In this way, for the first air deflectors 42 on one side, they can adjust the air flow coverage area to a larger range of the external region on the corresponding side through the concave surfaces, to better meet the uniform heat exchange requirements of heat exchangers 2 of different length specifications.

[0146] Similarly, for the second air deflector 43, the concave surface is also arranged in a back-facing manner. The two second air deflectors 43 are arranged in an up-down manner to guide the air flow towards the upper or lower side of the heat exchanger 2 by using the concave surface.

[0147] In an embodiment of the present application, for the fan assembly 3, the structure of the fan assembly 3 in the second embodiment can be adopted, that is, a separate partition plate 13 needs to be arranged in the shell 1 to meet the installation requirement of the fan assembly 3, and the air deflector assembly 4 also needs to be installed on the partition plate 13.

[0148] In another embodiment of the present application, for the fan assembly 3, the structure of the fan assembly 3 in the third embodiment can be adopted, in which case, the partition plate is integrated on the second mounting member 34 of the fan assembly 3 to serve as the partition plate by means of the structure of the spacing portion 346, and the air deflector assembly 4 needs to be installed on the spacing portion 346.

[0149] In the description of the above embodiments, the specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0150] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the 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.
