[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0045] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] The present invention provides a casing 100 of an air conditioner outdoor unit. Figures 1 to 5 In an embodiment of the present invention, the casing 100 of the air conditioner outdoor unit includes a shell 10, a first panel 20 and a second panel 30, wherein the shell 10 is provided with a fan chamber 10a and a compressor chamber 10b, the fan chamber 10a is used to install components such as a fan 200 and a heat exchanger, and the compressor chamber 10b is used to install components such as a compressor, a circuit board, a plate exchanger, a pipeline and a valve.

[0047] It should be noted that, in actual applications, the fan chamber 10a and the compressor chamber 10b can be interconnected, and there are various ways of connection. It can be that interconnected channels are formed inside the shell 10, or that a channel is connected outside the shell 10 to connect the fan chamber 10a and the compressor chamber 10b to each other. This arrangement allows the fan 200 to take away the heat in the compressor chamber 10b and play a role in heat dissipation.

[0048] The housing 10 is provided with an air inlet 10d and an air outlet 10c connected to the fan chamber 10a, and the housing 10 is also provided with a maintenance window 10e connected to the compressor chamber 10b. In the present embodiment, the air outlet 10c is circular corresponding to the running track of the fan blades of the fan 200. While ensuring the smooth exhaust of the fan 200, the air outlet 10c is made smaller, which can ensure the strength of the housing 10 and enhance the overall stability. Moreover, the air outlet 10c can be provided with a curved surface with a slope extending toward the center of the air outlet 10c in the housing 10, so as to reduce the rainwater from entering the fan chamber 10a. The air inlet 10d is in a grid shape to ensure the air intake of the fan chamber 10a and protect the interior of the fan chamber 10a.

[0049] The maintenance window 10e is square and can be used to observe the components in the compressor cavity 10b from the outside. The mainboard and other electrical components in the compressor cavity 10b can also be maintained and replaced through the maintenance window 10e. Of course, it is understandable that a detachable transparent panel can be provided on the maintenance window 10e, which is convenient for observation and can better protect the compressor cavity 10b from external dust, water vapor, etc. The present invention does not impose specific restrictions on the specific shapes of the air inlet 10d, the air outlet 10c and the maintenance window 10e, which can be square, round, diamond, etc.

[0050] The first panel 20 is fixedly connected to the housing 10, and the first panel 20 covers the air outlet 10c. The connection between the first panel 20 and the housing 10 includes, but is not limited to, bonding, welding, threaded connection, and snap connection. The materials of the first panel 20 and the second panel 30 may include, but are not limited to, plastic, metal, and other materials.

[0051] The first panel 20 is provided with a ventilation hole 20a connected to the air outlet 10c. The first panel 20 is provided with a plurality of holes to form the ventilation hole 20a. The plurality of holes make the first panel 20 as a whole present a flat grid structure. The shape of the hole can be various shapes, such as diamond, triangle, circle, square, etc., wherein the hot air can be discharged from the air outlet 10c through the ventilation hole 20a. Of course, it can be understood that the first panel 20 can be similar in shape to the air outlet 10c, just completely covering the air outlet 10c, or it can be larger than the air outlet 10c, and integrated with the shell 10 to make the air conditioner outdoor unit more beautiful.

[0052] The second panel 30 is rotatably connected to the housing 10, and the second panel 30 rotates relative to the housing 10 to open or cover the maintenance window 10e. There are many ways to rotatably connect the second panel 30 to the housing 10, which can be achieved by installing a hinge between the first panel 20 and the second panel 30, or by installing a rotatable connecting shaft between the first panel 20 and the second panel 30 to achieve the rotational connection. The second panel 30 can be similar in shape to the maintenance window 10e, just completely covering the maintenance window 10e, or it can be larger than the maintenance window 10e and integrated with the housing 10 to make the air conditioner outdoor unit more beautiful.

[0053] According to the above scheme, a shell 10 having a fan chamber 10a and a compressor chamber 10b is provided in the casing 100 of the air conditioner outdoor unit, and an air inlet 10d and an air outlet 10c connected to the fan chamber 10a, and a maintenance window 10e connected to the compressor chamber 10b are provided in the shell 10. Air with a relatively low external temperature can enter the shell 10 through the air inlet 10d, absorb the heat inside the shell 10, and then be discharged to the outside through the air outlet 10c. The first panel 20 is provided with a ventilation hole 20a, and the first panel 20 is fixedly connected to the shell 10 and covers the air outlet 10c, so that the first panel 20 can protect the interior of the fan chamber 10a, and prevent external foreign objects from interfering with or colliding with the components inside the fan chamber 10a. The second panel 30 is rotatably connected to the shell 10. In this way, the second panel 30 is rotated to cover the maintenance window 10e, so as to protect the interior of the compressor chamber 10b, and prevent external foreign objects from interfering with or colliding with the components inside the compressor chamber 10b. When the interior of the compressor chamber 10b needs maintenance and care , rotate the second panel 30 to open the maintenance window 10e, and the situation inside the compressor chamber 10b can be directly observed through the maintenance window 10e, and the integrity of the internal parts of the compressor chamber 10b can be visually checked. The internal parts of the compressor chamber 10b can also be replaced and repaired through the maintenance window 10e. The interior of the air-conditioning outdoor unit can be inspected without removing the second panel 30, which facilitates the maintenance of the air-conditioning outdoor unit. Moreover, only the second panel 30 needs to be rotated, which reduces the gravity on the rotating connection, makes it easy to open, and the operating space required to rotate the second panel 30 is smaller.

[0054] like Figure 2 and Figure 6As shown, the casing 100 of the air conditioner outdoor unit also includes a rotating shaft assembly 40, and the rotating shaft assembly 40 includes a fixed shaft 41 and two rotating seats 42. The fixed shaft 41 is fixedly connected to the shell 10, and the fixed shaft 41 is located on one side of the maintenance window 10e. The two rotating seats 42 are installed at intervals on the second panel 30, and the two rotating seats 42 are both rotatably connected to the fixed shaft 41. As an example, the two rotating seats 42 are located at both ends of the length direction of the fixed shaft 41, and the second panel 31 is rotatably connected to the fixed shaft 41 through the two rotating seats 42, and the fixed shaft 41 is fixedly connected to the shell 10. With this arrangement, the second panel 22 can form a rotatable and movable connection with the shell 10 through the two rotating shafts 24.

[0055] There are many ways to fix the fixed shaft 41 to the housing 10, such as welding, interference fit, bonding, threaded connection, clamping, etc. The two rotating seats 42 can be installed on the second panel 30 in a detachable fixed connection, such as threaded connection, clamping, or a non-detachable fixed connection, such as bonding, clamping, etc.

[0056] The two rotating shafts 42 are located at both ends of the fixed shaft 41 in the length direction. The two rotating seats 42 can disperse the gravity of the second panel 30 to the fixed shaft 41, avoid the fixed shaft 41 from being broken due to excessive force locally, and reduce the material hardness requirements for the fixed shaft 41. In another setting form, more rotating seats 42 can also be set. For example, the rotating seats 42 can be set to three, and the fixed shaft 41 is evenly divided into three parts in the length direction. The three rotating seats 42 are arranged at intervals in the three parts of the fixed shaft 41, which is conducive to increasing the stability of the rotating seats 42 and the fixed shaft 41. The materials of the two rotating seats 42 and the fixed shaft 41 can include but are not limited to plastics, metals and other materials with appropriate hardness.

[0057] The fixed shaft 41 includes a shaft body 411 and at least two mounting bosses 412. The at least two mounting bosses 412 are both arranged on the outer peripheral wall of the shaft body 411. Figure 5 and Fig. 9 In this embodiment, the outer peripheral wall of the shaft body 411 is provided with three mounting bosses 412. Of course, in other embodiments, the number of mounting bosses 412 can be set to two, four, five, etc. Among them, there are also many ways to set the mounting bosses 412. The mounting bosses 412 can be welded and fixed on the outer peripheral wall of the shaft body 411, or the mounting bosses 412 and the shaft body 411 can be integrally formed parts.

[0058] At least two mounting bosses 412 are also spaced apart along the axial direction of the shaft body 411 , and at least two mounting bosses 412 are fixedly connected to the shell 10 , so that the shaft body 411 is spaced apart from the shell 10 , and both rotating seats 42 are rotationally connected to the shaft body 411 , and the two rotating seats 42 are also spaced apart from the shell 10 .

[0059] There are also many ways to fix the mounting boss 412 and the housing 10. The mounting boss 412 and the housing 10 may be fixedly connected by screws inside the housing 10, or by welding, bonding, etc. Alternatively, a recessed mounting groove may be formed on the surface of the housing 10, and then a portion of the mounting boss 412 may be inserted into the mounting groove by interference fit, and then screwed and fixed. In this way, the fixed shaft 41 may be firmly fixed to the housing 10, so that the fixed shaft 41 can better withstand the gravity of the second panel 30.

[0060] Preferably, please refer to Figure 4 and Fig.10 In the solution of using screws to fix the mounting boss 412 to the housing 10, the screws are driven from the inside of the housing 10 to the outside. In this mounting method, it is not necessary to open a threaded hole through the fixed shaft 41. A mounting hole 412a is opened in the mounting boss 412, and a fixing hole 10f matching it is opened in the housing 10, and then the screws are screwed outward from the inside of the housing 10 to fix it. This arrangement reduces the erosion and corrosion of the inside of the fixed shaft 41 by rainwater.

[0061] The two rotating seats 42 are spaced apart from the shell 10 so that a gap is left between the second panel 30 fixedly connected to the two rotating seats 42 and the shell 10. This arrangement avoids the possibility that the rotating second panel 30 may interfere with the shell 10, resulting in difficulty in opening or closing the maintenance window 10e.

[0062] The air outlet 10c and the maintenance window 10e are arranged on the same side of the housing 10, and the fixed shaft 41 is located between the air outlet 10c and the maintenance window 10e. Figure 2 and Figure 6 In the illustrated scheme, the air outlet 10c and the maintenance window 10e are located on a plane on the front side of the shell 10 and are arranged relatively parallel. The fixed axis 41 is vertically arranged between the air outlet 10c and the maintenance window 10e. Of course, it can be understood that in other embodiments, the air outlet 10c and the maintenance window 10e can be arranged at intervals and can be arranged on different surfaces.

[0063] The first panel 20 and the second panel 30 are located on two opposite sides of the fixed shaft 41. The first panel 20 is also fixedly connected to the side of the fixed shaft 41 facing away from the air outlet 10c. The second panel 30 is located on the side of the fixed shaft 41 adjacent to the maintenance window 10e. The second panel 30 is rotatably connected to the fixed shaft 41 via two rotating seats 42.

[0064] There may be a variety of ways to fix the first panel 20 and the fixed shaft 41, such as welding, interference fit, bonding, threaded connection, snap connection, etc. This arrangement can improve the stability of the fixed shaft 41 relative to the second panel 30.

[0065] In this embodiment, the fixed shaft 41 and the two rotating seats 42 are located between the first panel 20 and the second panel 30. In this way, when the second panel 30 covers the maintenance window 10e, the connection between the fixed shaft 41 and the first panel 20 can be hidden between the first panel 20 and the second panel 30. Similarly, the connection between the two rotating seats 42 and the second panel 30 can also be hidden between the first panel 20 and the second panel 30. In this way, the air conditioner outdoor unit cannot be penetrated when facing rain, avoiding the risk of rusting of metal installation parts.

[0066] Please refer to 6 and Fig. 9 The two edges of the fixed shaft 41 and the two rotating seats 42 away from the housing 10 are provided with arc guide surfaces 44. The arrangement of the arc guide surfaces 44 allows the second panel 30 to rotate relative to the first panel 20, leaving a certain rotation space for the rotating seat 42, so as to avoid the mounting platform 421 of the second panel 30 from interfering with the first panel 20 when the first panel 20 rotates. When the air conditioner outdoor unit is washed by rain, the arc guide surfaces 44 can also play a role in draining the rain, thereby reducing the corrosion of the air conditioner outdoor unit by rain, and its appearance is also more beautiful.

[0067] like Figures 7 to 9 As shown, the side surface of the first panel 20 facing the fixed shaft 41 is concavely provided with a positioning hole 20b, and the side surface of the fixed shaft 41 facing the first panel 20 is provided with a positioning column 413, and the positioning column 413 is plugged into the positioning hole 20b. This arrangement facilitates assembly work and can also enhance the stability of the overall structure.

[0068] There are many ways to set the positioning column 413. In this embodiment, the positioning column 413 is in a square shape and is integrally formed with the fixed shaft 41. The positioning hole 20b corresponding to the positioning column 413 is in a square hole shape. In other embodiments, the positioning column 413 can be cylindrical, and a chamfer is provided at the end away from the fixed shaft 41 to facilitate the cooperation with the positioning hole 20b. Of course, it can also be in a triangular column shape, a hexagonal column shape, etc. Moreover, the shaft diameter of the positioning column 413 can also be set to be gradual, and the gradually decreasing shaft diameter is convenient for cooperation with the positioning hole 20b.

[0069] like Figures 9 to 13As shown, both end surfaces of the fixed shaft 41 in the length direction are recessed with pivot holes 411a, and the pivot holes 411a are holes similar to cylindrical shapes. Each rotating seat 42 includes a mounting platform 421 and a pivot axis 422. Each mounting platform 421, in the present embodiment, is provided with a connecting hole 42b, and the connecting hole 42b is fixedly connected to the second panel 30 by screwing, and one end of each pivot axis 422 is connected to the corresponding mounting platform 421, and the other end of each pivot axis 422 is rotatably connected to the pivot hole 411a at the corresponding end.

[0070] There are many ways to connect the mounting platform 421 and the pivot shaft 422. In one setting, a shaft mounting hole is provided at one end of each mounting platform 421 connected to the pivot shaft 422. After the pivot shaft 422 is inserted into the shaft mounting hole, it is welded. This setting can firmly fix the pivot shaft 422 to the mounting platform 421, and ensure that the axial direction of the pivot shaft 422 is parallel to the mounting platform 421, which also reduces the processing difficulty.

[0071] In another arrangement, the pivot shaft 422 is threadedly engaged with the shaft mounting hole. Of course, it is understandable that the pivot shaft 422 and the mounting platform 421 can be integrally formed parts, which can reduce the requirements of the installation process and enhance the stability of the structure.

[0072] Furthermore, a limit groove 42a is recessed on the outer wall of each pivot shaft 422, and each limit groove 42a is extended along the circumference of the corresponding pivot shaft 422. The rotating shaft assembly 40 also includes two limit pins 43, and the two limit pins 43 are respectively arranged at both ends of the fixed shaft 41 in the length direction. The two limit pins 43 are at least partially located in the corresponding limit groove 42a to limit the corresponding pivot shaft 422 from being separated from the corresponding pivot hole 411a, so that each rotating seat 42 is stably rotatably connected to the corresponding end of the fixed shaft 41 without any risk of separation, further ensuring the stability of the rotational connection between the first panel 20 and the second panel 30, and can improve the reliability of rotating the second panel 30 to open or cover the maintenance window 10e.

[0073] In this embodiment, the outer wall of each pivot shaft 422 is recessed with an annular limiting groove 42a with a semicircular cross-section. Of course, in other embodiments, the cross-section of the limiting groove 42a can be in other shapes, such as a square, and the limiting pin 43 corresponding to the limiting groove 42a is cylindrical.

[0074] The installation of the limit pin 43 can be done by opening a through hole connected to the pivot hole 411a on the circumference of the fixed shaft 41, and the limit pin 43 has a clearance fit or an interference fit with the through hole. Alternatively, a through hole penetrating the fixed shaft 41 and passing through the pivot hole 411a can be opened on the circumference of the fixed shaft 41, and the through hole can be made gradually smaller, and the corresponding outer diameter of the limit pin 43 is also made gradually smaller, so that the installation of the limit pin 43 is convenient and it is not easy to fall off.

[0075] The cooperation between the limiting pin 43 and the limiting groove 42a limits the axial movement of the pivot shaft 422, prevents the pivot shaft 422 from being separated from the corresponding pivot hole 411a, and improves the reliability of the rotation connection.

[0076] Furthermore, one end surface of the fixed shaft 41 in the length direction is recessed with a limiting hole 411b, and the limiting hole 411b is located on the circumferential side of the pivot hole 411a on the corresponding side. The limiting hole 411b is also extended along the circumference of the pivot hole 411a on the corresponding side. The mounting platform 421 adjacent to the limiting hole 411b of the two mounting platforms 421 is provided with a limiting protrusion 423, and the limiting protrusion 423 extends into the limiting hole 411b and is clearance-matched with the limiting hole 411b.

[0077] like Fig.13 In the illustrated solution, the limiting hole 411b may be arranged to be connected to the pivot hole 411a, and the cross-sectional width of the connecting portion between the limiting hole 411b and the pivot hole 411a is smaller than the diameter of the pivot shaft 422, that is, the pivot hole 411a still retains more than half of the arc. Fig.11 With this arrangement, the pivot shaft 422 can extend into the limiting hole 411b through the connection between the pivot hole 411a and the limiting hole 411b, and the limiting pin 43 can be attached to the hole wall of the limiting hole 411b or embedded in the hole wall of the limiting hole 411b to extend the limiting hole 411b and cooperate with the limiting groove 42a, making the structure more compact, material-saving and lightweight, and also making the installation process clear at a glance, thereby improving the installation efficiency.

[0078] Of course, it is understandable that the limiting hole 411b can also be separately provided on the end surface of the fixed shaft 41. The setting mode of the limiting protrusion 423 is similar to the connection mode between the pivot shaft 422 and the mounting platform 421, which can be welding, threaded connection, integral molding, etc., which will not be described one by one here.

[0079] The limiting protrusion 423 is limited to move between the two hole walls of the limiting hole 411b, so as to limit the rotation angle of the mounting platform 421 relative to the fixed shaft 41, thereby limiting the opening range of the second panel 30, and avoiding interference with the first panel 20. The opening range of the second panel 30 can be adjusted according to the distance between the limiting protrusion 423 and the pivot axis 422 or the circumferential width of the limiting hole 411b, that is, the farther the distance between the limiting protrusion 423 and the pivot axis 422, the larger the opening range, the smaller the circumferential width of the limiting hole 411b, and vice versa.

[0080] In this embodiment, the first panel 20 can be connected to the shell 10 after being installed with the second panel 30 via the rotating shaft assembly 40. In this way, the first panel 20 and the second panel 30 are installed in a separate, modular manner, so that the installation of the first panel 20 and the second panel 30 is not affected by other components of the air conditioner outdoor unit (for example, in conventional designs, the first panel 20 and the second panel 30 are fixedly matched with the upper cover 12). It is only necessary to install the first panel 30 on the shell 10 of the air conditioner outdoor unit to complete the installation process, thereby improving the installation efficiency of the air conditioner outdoor unit.

[0081] Specifically, the two rotating seats 42 are rotatably connected to the two ends of the fixed shaft 411 in the length direction through the pivot shaft 422, and a through hole connected to the pivot hole 411a is opened in the circumference of the fixed shaft 411, and the limiting pin 43 is inserted into the pivot hole 411a through the through hole and matched with the limiting groove 42a of the pivot shaft 422, so that the second panel 30 is rotatably connected to the fixed shaft 41 through the two rotating seats 42. After the second panel 30 and the fixed shaft 41 are installed, the second panel 30 is turned over and the positioning hole 20b of the first panel 20 is plugged and matched with the positioning column 413, and then the first panel 20 is installed on the fixed shaft 41 by screwing, and the installation is completed. When the first panel 20 and the second panel 30 need to be installed on the housing 10 of the air conditioner outdoor unit, it is only necessary to fix the first panel 21 of the front panel assembly 20 to the housing 10 of the air conditioner outdoor unit to complete the installation. Preferably, the first panel 21 is provided with four holes at intervals and fixed to the housing 10 by screwing.

[0082] With reference to the above installation process, it can be understood that the disassembly of the air conditioner outdoor unit is also very convenient, which can improve the maintenance efficiency of the air conditioner outdoor unit, and will not be described in detail.

[0083] like Figure 2 As shown, the casing 100 of the air conditioner outdoor unit further includes a first connecting member 50 and a second connecting member 60. The first connecting member 50 is installed on the second panel 30, and the second connecting member 60 is installed on the shell 10. The first connecting member 50 and the second connecting member 60 are detachably connected.

[0084] The detachable connection between the first connector 50 and the second connector 60 includes, but is not limited to, threaded connection, snap connection, magnetic attraction, etc. In this way, the second panel 30 covers the maintenance window 10e and fixes the second panel 30 on the housing 10, so that it will not be easily opened by external interference factors (such as foreign objects blown by strong wind), and it is very convenient to open. The number of pairs of the first connector 50 and the second connector 60 can be multiple.

[0085] Preferably, the first connecting member 50 is a first magnetic member, the second connecting member 60 is a second magnetic member, and the first magnetic member and the second magnetic member are magnetically attracted to each other. This arrangement is intended to improve the efficiency and convenience of opening or covering the maintenance window 10e.

[0086] When covering the maintenance window 10e, the user only needs to gently rotate the second panel 30 to the vicinity of the surface of the housing 10, and the first magnetic member and the second magnetic member can be magnetically attracted to each other and fit tightly together, so that the second panel 30 can cover the maintenance window 10e and be fixed on the housing 10. In order to facilitate opening the maintenance window 10e, a handle can be provided on the second panel 30, and the handle is preferably formed by being concave on the side of the second panel 30 away from the first panel 20.

[0087] Please refer to Figure 2 and Figures 14 to 16 The casing 100 of the air conditioner outdoor unit also includes a mounting base 70, and the mounting base 70 includes a mounting plate 71 and two elastic arms 72. The mounting plate 71 is connected to the surface of the second panel 30 facing the shell 10. The two elastic arms 72 are arranged on the mounting plate 71 at intervals. The two elastic arms 72 both extend toward the shell 10. The two elastic arms 72 are also inclined in directions away from each other. The first magnetic member includes a connecting plate 51 and a magnet 53. Both ends of the connecting plate 51 in the length direction are penetrated by assembly holes 52. The assembly holes 52 of the connecting plate 51 in the length direction cooperate with the corresponding elastic arms 72 to be connected to the mounting plate 71 under the action of the two elastic arms 72. The magnet 53 is fixedly installed on the side of the connecting plate 51 facing away from the mounting plate 71.

[0088] There are many ways to connect the mounting plate 71 to the second panel 30. The second panel 30 may have a slot, the mounting plate 71 may be U-shaped, and one side of the mounting plate 71 may be fitted into the slot. The mounting plate 71 may be fixed to the second panel 30 by screws, or the mounting plate 71 may be welded to the second panel 30. The above-mentioned installation seat 70 can play a role of shock absorption and buffering when the second panel 30 is rotated to cover the maintenance window 10e.

[0089] like Figure 4 and Figure 5As shown, the shell 10 includes a bottom plate 11, an upper cover 12, a front panel 13, a rear panel 14, a side panel 15, a partition 16 and a guard plate 17, wherein the upper cover 12 and the bottom plate 11 are spaced apart in the up-down direction, the front panel 13, the rear panel 14 and the side panel 15 are installed between the upper cover 12 and the bottom plate 11, the front panel 13 and the rear panel 14 are spaced apart in the front-back direction, the length of the front panel 13 in the left-right direction is smaller than the length of the rear panel 14 in the left-right direction, and the side panel 15 connects one side of the front panel 13 in the left-right direction with the corresponding side of the rear panel 14 in the left-right direction.

[0090] The partition 16 is installed between the upper cover 12 and the bottom plate 11. The partition 16 connects the other side of the front panel 13 in the left-right direction with the middle of the rear panel 14. The bottom plate 11, the upper cover 12, the front panel 13, the rear panel 14, the side panels 15 and the partition 16 are collectively arranged to form a fan chamber 10a. The air inlet 10d is provided on the rear panel 14, and the air outlet 10c is provided on the front panel 13, wherein the front panel 13 can be used to be fixedly connected with the fan 200, so that the fan 200 is suspended on the bottom plate 11. It can be understood that the air inlet 10d can also be provided on the side panels 15, the upper cover 12, etc.

[0091] The guard plate 17 is installed between the upper cover 12 and the bottom plate 11. The guard plate 17 is L-shaped. One side of the guard plate 17 is connected to the side of the rear panel 14 away from the side panel 15, and the other side of the guard plate 17 is connected to the side of the front panel 13 away from the side panel 15. The bottom plate 11, the upper cover 12, the partition 16, and the guard plate 17 are together arranged to form a compressor chamber 10b. The maintenance window 10e is opened on the guard plate 17.

[0092] In this embodiment, the outer contour of the shell 10 is generally in the shape of a square rectangular parallelepiped, and may also be in the form of a cylinder, a cube, a flat disk, etc. The material of the shell 10 may include but is not limited to plastic, metal and other materials. To further protect the shell 10, a layer of protective paint may also be provided on the surface.

[0093] The connection between the bottom plate 11, the upper cover 12, the front panel 13, the rear panel 14, the side panels 15, the partition 16 and the guard plate 17 can be threaded connection, welding, snap connection, etc., wherein the preferred connection mode of the guard plate 17 with the side panels 15 and the front panel 13 is detachable connection, specifically, snap connection. In this way, removing the guard plate 17 can provide a larger working space for maintenance workers to improve efficiency. Of course, it is understandable that the guard plate 17 can also be set as a front guard plate and a side guard plate, wherein the front guard plate and the side guard plate are detachably connected, so that maintenance workers can choose a convenient and fast working space according to actual conditions to improve efficiency.

[0094] Furthermore, in order to facilitate the disassembly of the guard plate 17, a buckle can be provided in the inner recess of the guard plate 17 to improve the convenience of disassembly. Reinforcement ribs can also be provided at the edges of the maintenance window 10e and the second panel 30 to improve the strength of the board. Among them, a through hole can also be provided in the partition 16 to connect the fan chamber 10a and the compressor chamber 10b, so that the start of the fan 200 can also drive the air flow in the compressor chamber 10b to play a role in heat dissipation.
