Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air supply system for an air conditioner outdoor unit and an air conditioner outdoor unit. Background Art

[0002] At present, in the layout of ordinary top-outlet air conditioner outdoor units, the air supply system is arranged in the top area of ​​the heat exchanger, and the bottom of the heat exchanger is arranged on the chassis of the air conditioner outdoor unit. The air supply system consists of a motor group (including a motor and a motor fixing bracket), a fan, and an air guide ring. The height of the fan is also higher than the top of the heat exchanger. Because the fan is higher than the top of the heat exchanger, the wind speed in the middle and lower parts of the heat exchanger far from the fan will be lower. There is a low wind speed flowing through the middle and lower areas of the heat exchanger, resulting in low heat exchange efficiency of the heat exchanger in this area, while the wind speed in the upper area of ​​the heat exchanger close to the fan is higher. Due to the uneven wind field, the heat exchanger cannot be used to its due high efficiency. The air conditioner outdoor unit has the problem of low heat exchange efficiency and weak overall capacity.

[0003] The related technology provides an outdoor unit, in which the top of the heat exchanger is against the top wall of the casing and the bottom of the heat exchanger is fixed on the bottom wall of the casing, so that the height of the heat exchanger is equal to the height of the side wall of the casing. The fan is arranged flush with a part of the heat exchanger, and the height of the outdoor unit is reduced while the height of the heat exchanger remains unchanged. The height of the outdoor unit is reduced, so the distance between the air inlet at the bottom of the side wall of the outdoor unit and the fan is reduced, thereby reducing the difference in distance between the top and bottom of the side wall of the outdoor unit and the fan, and correspondingly reducing the wind speed difference between the wind speed at the bottom of the side wall of the casing and the wind speed at the top of the side wall, so that the difference in wind speed between the upper and lower positions is smaller.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Although the related technology can reduce the height of the outdoor unit by arranging the fan flush with part of the heat exchanger, the relative position of the fan and the casing is fixed and cannot be adjusted, and the layout cannot be flexibly combined. Due to layout restrictions, the overall height of the air conditioner outdoor unit is fixed, and the height of the heat exchanger is also fixed. For the heat exchangers of air conditioner outdoor units of different capacity segments, the wind field cannot be adjusted by changing the height of the heat exchanger and the corresponding height of the air supply system, which cannot meet different installation scenarios and wastes costs.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0053] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0054] Combination Figure 1-4 As shown, the embodiment of the present disclosure provides an air supply system 10 for an air conditioner outdoor unit, the air conditioner outdoor unit includes a heat exchanger 50, combined with Figure 1-7 As shown, the air supply system 10 includes: a fan 11, a motor group 12 and an air guide ring 20.

[0055] Combination Figure 1-4 As shown, the motor group 12 is connected to the fan 11; the air guide ring 20 includes a guide tube 30 and a base 40, the guide tube 30 is provided with a through air outlet 31, and the fan 11 and the motor group 12 are arranged in the guide tube 30; the base 40 is arranged at the first end 36 of the guide tube 30 and has an extension wall 43 extending outward along the circumference of the air outlet 31 of the first end 36, and the edge of the extension wall 43 is provided with a folding structure 41 protruding from the wall surfaces on both sides respectively, and the overall outer size of the base 40 is adapted to the cross-sectional size of the heat exchanger 50, so as to facilitate the air guide ring to be assembled to the end of the heat exchanger When the air guide ring 20 is installed in the forward direction, the first side wall surface 432 of the extension wall 43 away from the guide tube 30 and the first folding structure 412 protruding from the first side wall surface 432 are wrapped and overlapped on the heat exchanger end 51; when the air guide ring is installed in the reverse direction, the second side wall surface 431 of the extension wall 43 located on the guide tube 30 side and the second folding structure 411 protruding from the second side wall surface 431 are wrapped and overlapped on the heat exchanger end 51.

[0056] The heat exchanger end 51 refers to an end of the heat exchanger located at the air outlet side, close to the air supply system 10, along the air outlet direction of the air conditioner outdoor unit. The overall size of the base 40 is adapted to the cross-sectional size of the heat exchanger, including the case where the overall size of the base 40 is greater than or equal to the cross-sectional size of the heat exchanger 50.

[0057] Using the air supply system 10 for the air conditioner outdoor unit provided by the embodiment of the present disclosure, the extension wall 43 of the base 40 of the air guide ring 20 and the folding structure 41 together form a T-shaped folding structure. When the air guide ring 20 is assembled to the end 51 of the heat exchanger, the side wall surface of the extension wall 43 and the folding structure 41 on the same side can be wrapped and overlapped on the heat exchanger end 51, so that the air guide ring 20 can be installed forward or 180° reversed, while improving the sealing and restraining effect between the air guide ring 20 and the heat exchanger, avoiding the problem of low heat exchange efficiency caused by air leakage at the bottom of the air guide ring 20 and the end 51 of the heat exchanger. In this way, the overall layout of the air conditioner outdoor unit can be carried out according to different scenes with heat exchangers of different heights.

[0058] The air supply system 10 for an air conditioner outdoor unit provided in the present application is applicable to a variety of air conditioner outdoor units, including an assembly method in which the heat exchanger is placed vertically and the heat exchanger and the air supply system 10 are installed vertically; or an assembly method in which the heat exchanger is placed horizontally and the heat exchanger and the air supply system 10 are installed horizontally.

[0059] Optionally, the air outlet 31 of the guide tube 30 is a circular air outlet 31. The circular air outlet 31 is designed to allow air flow to pass smoothly, reduce resistance, improve wind direction conduction efficiency, and effectively reduce noise generated when air flows.

[0060] Optionally, the motor group 12 is located on a side away from the air outlet side of the fan 11 .

[0061] The vertical installation of the heat exchanger and the air supply system 10 is used as an example for explanation. When the air guide ring 20 is installed in the forward direction or in the reverse direction, the fan 11 is arranged above the motor group 12. Placing the fan 11 above the motor group 12 can make the fixed center of gravity of the motor group 12 low, reduce the vibration of the air conditioner outdoor unit and the fan 11, and reduce noise, which is more conducive to the stability of the motor fan 11 during operation. At the same time, when the air guide ring 20 is installed in the forward direction or in the reverse direction, the motor group 12 and the fan 11 are universal components and have the same rotation direction, ensuring that the air outlet direction of the fan 11 is upward, which can avoid affecting the heat exchange efficiency of the heat exchanger 50 due to the reverse installation.

[0062] Optionally, combined Figure 1 and Figure 4 As shown, the fan 11 is located in the middle of the axial direction of the guide tube 30 , and the inner diameter of the guide tube 30 is greater than or equal to the diameter of the fan 11 .

[0063] The motor group 12 and the fan 11 are arranged in the guide tube 30 of the air guide ring 20, and the overall height position of the fan 11 is in the middle position area of ​​the axial direction of the guide tube 30, which can not only better guide the wind field where the fan 11 rotates and works, but also ensure effective protection for the fan 11. At the same time, the fan 11 is arranged in the middle of the guide tube 30, which can ensure that the distance between the fan 11 and the air outlet 31 at the first end 36 of the guide tube 30 when the fan 11 is installed in a 180° reverse direction is the same or similar to the distance between the fan 11 and the air outlet 31 at the second end 37 of the guide tube 30 when the fan 11 is installed in a forward direction, thereby maintaining the uniformity of the wind field and giving full play to the efficient heat exchange of the heat exchanger 50.

[0064] When the overall height position of the fan 11 is in the middle position area in the axial direction of the guide tube 30, the outer edge of the fan blades of the fan 11 is located at the edge side of the overall structure of the fan 11. Relative to the fan 11 as a whole, the outer edge of the fan blades of the fan 11 is closer to the air outlet 31 at the first end 36 or the air outlet 31 at the second end 37 of the guide tube 30. When the air guide ring 20 is installed in the forward direction, the fan blades of the fan 11 are relatively close to the air outlet 31 at the second end 37 of the guide tube 30; when the air guide ring 20 is installed in the reverse direction, the fan blades of the fan 11 are relatively close to the air outlet 31 at the first end 36 of the guide tube 30.

[0065] The diameter of the fan 11 is usually 10-15 mm, and the inner diameter of the guide tube 30 is greater than or equal to the diameter of the fan 11, which can ensure the normal rotation of the fan 11, effectively ensure the air volume, and prevent problems such as abnormal noise and wear.

[0066] Optionally, combined Figure 2As shown, the guide tube 30 is provided with a plurality of positioning structures 32 , which are symmetrically arranged along the air outlet axis direction, and are used to fix the motor group 12 in the guide tube 30 and close to the first end 36 side or the second end 37 side of the guide tube 30 .

[0067] A plurality of positioning structures 32 are arranged symmetrically along the air outlet axis direction of the guide tube 30, including a first positioning structure 32 close to the base 40 along the air outlet axis direction, and a second positioning structure 32 far from the base 40 along the air outlet axis direction, and the first positioning structure 32 and the second positioning structure 32 are symmetrically arranged. When the air guide ring is installed in the forward direction, the motor group 12 is fixed in the guide tube 30 and close to the first end 36 side of the guide tube 30. When the air guide ring is installed in the reverse direction, the motor group 12 is fixed in the guide tube 30 and close to the second end 37 side of the guide tube 30. In this way, the motor group 12 can always be located on the side away from the air outlet of the fan 11, which can avoid affecting the air supply effect. The motor group 12 is fixed by the symmetrically arranged positioning structures 32, so as to achieve reliable fixation and constraint between the fan 11 and the motor group 12 when the air guide ring 20 is installed in the forward direction or reverse direction, and the normal operation of the air supply system 10 is also satisfied.

[0068] The vertical installation of the heat exchanger and the air supply system 10 is used as an example for explanation. When the air guide ring 20 is installed in the forward direction, the air guide tube is located above the base 40. In order to make the motor group 12 located on the side away from the air outlet of the fan 11, the motor group 12 is fixed to the first positioning structure 32, and the motor group 12 is fixed to the side close to the first end 36 of the guide tube 30. At this time, the motor group 12 is located below the fan 11. When the air guide ring 20 is installed in reverse, the air guide tube is located below the base 40. In order to make the motor group 12 located on the side away from the air outlet of the fan 11, the motor group 12 is fixed to the second positioning structure 32, and the motor group 12 is fixed to the side close to the second end 37 of the guide tube 30. At this time, the motor group 12 is located below the fan 11.

[0069] At the same time, when the fan 11 is located in the middle position of the guide tube 30 in the axial direction, the fan 11 is always at the same height of the guide tube 30, and the positioning structure 32 on the guide tube 30 is universal, which improves the versatility of the components and optimizes the mold process.

[0070] Optionally, the positioning structure 32 is a positioning through hole 321. The motor group 12 is detachably fixed to the guide tube 30 by bolt and nut fixing. The production process of the positioning through hole 321 is simple, and the fixed installation is easy to operate. It can also be detachably fixed by plugging. The positioning through hole 321 can be a round through hole or a through hole of other shapes. The motor group 12 includes a motor and a motor bracket. The motor bracket is fixed to the guide tube 30 by bolt and nut fixing through the positioning through hole 321.

[0071] It is understandable that the positioning structure 32 may also be a hook structure or other structure that enables the motor group 12 to be detachably fixed to the guide tube 30 .

At the same time, the distance between the drainage hole 44 and the folded edge structure 41 cannot be too large to avoid water on the air guide ring 20 from flowing into other system components in the air conditioner outdoor unit.

[0084] Combination Figure 5-7 As shown, the embodiment of the present disclosure provides an air conditioner outdoor unit, comprising a housing 60, a heat exchanger 50, and an air supply system 10 for the air conditioner outdoor unit as described in any of the above embodiments. The housing 60 encloses an accommodation space 61; the heat exchanger 50 is arranged in the accommodation space 61 and extends along the circumference of the housing 60; the air supply system 10 is connected to the housing 60 and abuts against the heat exchanger end 51 on the air outlet side.

[0085] The air conditioner outdoor unit provided in the embodiment of the present disclosure includes the air supply system 10 for the air conditioner outdoor unit described in any of the above embodiments, and thus has all the beneficial effects of the air supply system 10 for the air conditioner outdoor unit described in any of the above embodiments, which will not be repeated here.

[0086] In the air supply system 10 for the air conditioner outdoor unit provided in the present application, the air guide ring 20 can be installed in the forward direction or in the reverse direction. By designing different installation positions of the air supply system 10 or adopting different installation directions of the air guide ring 20, the overall layout of the air conditioner outdoor unit can be coordinated with heat exchangers 50 of different heights, thereby optimizing the overall layout of the air conditioner outdoor unit.

[0087] Optionally, combined Figure 5 As shown, the air supply system 10 is arranged in the accommodating space 61; the base 40 is connected to the shell 60, and the first side wall surface 432 of the extension wall 43 away from the guide tube 30 side and the first folding structure 412 protruding from the first side wall surface 432 are wrapped and overlapped at the heat exchanger end 51; the fan is arranged near the second end 37 side of the guide tube 30; the motor group 12 is arranged near the first end 36 side of the guide tube 30; wherein, along the air outlet direction, the length of the heat exchanger is less than the length of the shell 60, and the total length of the length H1 of the heat exchanger and the length H3 of the air supply system is less than or equal to the length H2 of the shell 60.

[0088] In the air outlet direction, the length H1 of the heat exchanger is not equal to the length H2 of the shell, and usually the length H1 of the heat exchanger is smaller than the length H2 of the shell. In this case, the layout is described by taking the vertical assembly of the air supply system 10 and the heat exchanger 50 as an example.

[0089] The air supply system 10 is arranged in the accommodating space 61, and the air supply system 10 is arranged above the heat exchanger 50. The height difference between the length H1 of the heat exchanger and the length H2 of the shell is the length H3 of the air supply system, and the total length of the air conditioner outdoor unit is equal to the length of the shell. The total height of the length H1 of the heat exchanger and the length H3 of the air supply system can also be slightly less than the length H2 of the shell. The air supply system 10 adopts a forward installation scheme, and the air guide tube is located above the base 40. The lower side surface 432 of the extension wall 43 of the base 40 and the lower side 412 of the folding structure form a wrapping space, which is overlapped at the end 51 of the heat exchanger, and a sealed space is formed between the base 40 and the heat exchanger 50, so that the airflow can only flow through the air outlet 31 of the guide tube 30. A screw fastening hole 421 is reserved on the folding structure 41 of the base 40 at the bottom of the air guide ring 20, and corresponding through holes are also reserved on the left and right side panels and the front and rear guard plates of the shell 60. The air guide ring 20 and the shell 60 are fixed with screws to fix and constrain the air supply system 10 to ensure the reliability of the air supply system 10 in the air conditioner outdoor unit. The overall size of the base 40 is larger than the boundary size of the circle around the heat exchanger end 51. The extension wall 43 of the base 40 and the upper and lower sides of the folding structure 41 can be wrapped and overlapped on the heat exchanger end 51, and the folding structure 41 can overlap between the heat exchanger end 51 and the shell 60.

[0090] The heat exchanger 50 of the air conditioner outdoor unit is designed to be low in height, and the installation position of the air supply system 10 is also low. The air supply system 10 is close to the bottom of the heat exchanger 50. When the fan 11 rotates at high speed, all heat exchange surfaces of the overall heat exchanger 50 can exchange heat, meeting the capacity requirements set by the air conditioner outdoor unit. Moreover, the air supply system 10 does not exceed the total height of the air conditioner outdoor unit, which improves the control of the total height of the air conditioner outdoor unit, the amount of the heat exchanger 50, the optimization of the wind speed of the wind field at the bottom of the heat exchanger 50, and the heat exchange effect.

[0091] Optionally, combined Figure 6 As shown, the air supply system 10 is arranged outside the accommodating space 61, above the shell 60; the base 40 is connected to the shell 60, and the first side wall surface 432 of the extension wall 43 away from the guide tube 30 side and the first folding structure 412 protruding from the first side wall surface 432 are wrapped and overlapped at the heat exchanger end 51; the fan 11 is arranged near the second end 37 side of the guide tube 30; the motor group 12 is arranged near the first end 36 side of the guide tube 30; wherein, along the air outlet direction, the length of the heat exchanger 50 is equal to the length of the shell 60.

[0092] When the length H1 of the heat exchanger is equal to the length H2 of the shell, the layout is described by taking the vertical assembly of the air supply system 10 and the heat exchanger 50 as an example.

[0093] The air supply system 10 can be arranged outside the accommodation space 61 located above the shell 60. The air supply system 10 is installed in a forward direction, and the air guide tube is located above the base 40. The lower side surface 432 of the extension wall 43 of the base 40 and the lower side 412 of the folding structure form a wrapping space, which is wrapped and overlapped at the end 51 of the heat exchanger. A sealed space is formed between the base 40 and the heat exchanger 50, so that the air flow can only flow through the air outlet 31 of the guide tube 30. The folding structure 41 of the base 40 at the bottom of the air guide ring 20 and the left and right side panels and the front and rear guard plates of the shell 60 are fixed with screws to form an effective and reliable position positioning.

[0094] In this layout, the heat exchanger 50 can be at the maximum height, and the length H1 of the heat exchanger is equal to the length H2 of the shell. In this case, the total height of the air conditioner outdoor unit is the sum of the length H2 of the shell and the length H3 of the air supply system. The overall heat exchange area can be increased, and the heat exchange capacity of the air conditioner outdoor unit can be maximized to meet the scene with high capacity requirements.

[0095] It can be understood that due to installation requirements, the length H2 of the shell may also be slightly greater than the length H1 of the heat exchanger.

[0096] Optionally, combined Figure 7As shown, the air supply system 10 is arranged in the accommodating space 61; the base 40 is connected to the shell 60, and the second side wall surface 431 of the extension wall 43 located on the side of the guide tube 30 and the second folding structure 411 protruding from the second side wall surface 431 are wrapped and overlapped at the heat exchanger end 51; the fan 11 is arranged near the first end 36 side of the guide tube 30; the motor group 12 is arranged near the second end 37 side of the guide tube 30; wherein, along the air outlet direction, the length H1 of the heat exchanger is equal to the length H2 of the shell.

[0097] When the length H1 of the heat exchanger is equal to the length H2 of the shell, in the scenario where the installation height of the whole machine is limited, the unified exhaust duct is connected, or the single unit capacity can be reduced, the air guide ring 20 of the air supply system 10 can be rotated 180° and then reversely installed without changing the shell 60 and the heat exchanger 50. The layout is described by taking the vertical assembly of the air supply system 10 and the heat exchanger 50 as an example.

[0098] The directions of the fan 11 and the motor unit 12 remain unchanged, and the fan 11 is always arranged above the motor unit 12. After the air guide ring 20 rotates 180°, it is fixed together with the motor unit 12 through the positioning structure 32 on the guide tube 30, which can also realize the normal operation of the air conditioner outdoor unit and achieve the setting requirements such as cooling or heating.

[0099] It can be understood that due to installation requirements, the length H2 of the shell may also be slightly greater than the length H1 of the heat exchanger.

[0100] Optionally, the air conditioner outdoor unit also includes a protective net, which is arranged at the shell end 62 on the air outlet side or the end of the air guide ring 20 on the air outlet side; wherein, when the air supply system 10 is located in the accommodating space 61, the protective net is arranged at the shell end 62 on the air outlet side or the end of the air guide ring 20 on the air outlet side; when the air supply system 10 is located outside the accommodating space 61, the protective net is arranged at the end of the air guide ring 20 on the air outlet side.

[0101] The housing end 62 on the air outlet side is one end of the housing 60 connected to the air supply system 10. When installed in the forward direction, the air guide ring end on the air outlet side is on the second end 37 side of the air guide cylinder; when installed in the reverse direction, the air guide ring end on the air outlet side is on the first end 36 side of the air guide cylinder or on the first side wall surface 432 side of the extension wall 43.

[0102] The air conditioner outer unit is protected by a protective net, which can prevent debris from falling in and improve the safety of the air outlet 31. The protective net can be fixed by screws at the circular air outlet 31 at the end of the air guide ring 20.

[0103] When the air supply system 10 is located in the accommodation space 61, the air guide ring 20 is installed in the forward direction and in the reverse direction. The end of the air guide ring 20 on the air outlet side is flush with or lower than the shell end 62. At this time, the protective net can be set at the shell end 62, or the protective net can be set at the first end 36 side or the second end 37 side of the air guide ring 20 according to the assembly method.

[0104] When the air supply system 10 is outside the accommodation space 61, the air guide ring 20 is installed forwardly, and the end of the air guide ring 20 on the air outlet side is higher than the shell end 62. At this time, the protective net is arranged on the second end 37 side of the air guide ring 20. The protective net can be a circular protective net.

[0105] The heat exchanger 50 involved in the present application includes a heat exchanger 50 having a cross-sectional shape of G-type, mouth-type, L+U-type, Q-type, U-type, L+L-type or shapes similar to the above.

[0106] This application optimizes the overall layout of the air conditioner outdoor unit, designs the air supply system 10 of the air conditioner outdoor unit as a 180° reverse installation structure, and coordinates the heat exchangers 50 of different heights to carry out the overall layout of the air conditioner outdoor unit, and adjusts the layout of the air conditioner outdoor unit in a targeted manner according to the needs of different capacity segments and different installation scenarios, so as to optimize the wind speed of the heat exchanger 50, optimize the layout of the wind field and the heat exchange volume, and optimize the cost, further improve the cooling and heating capacity of the air conditioner outdoor unit, and through flexible air supply layout and adjustable height. Compared with related technologies, this application can solve the problems of fixed layout design of ordinary air conditioner outdoor units, inability to achieve more accurate cost control, poor heat exchange efficiency and poor wind field of the heat exchanger 50, high transportation and storage costs caused by limited installation after transportation, high installation restrictions, and inability to meet the needs of a wider range of installation scenarios.
