Description

Technical Field

[0001] This disclosure relates to the field of marine air conditioning technology, and in particular to a marine air conditioning outdoor unit and a marine air conditioning unit. Background Technology

[0002] In modern ship design, air conditioning units are crucial for maintaining a comfortable internal environment and ensuring the normal operation of equipment. Their performance and reliability are of paramount importance. However, ships typically operate in complex marine environments, facing harsh conditions such as strong winds, salt spray, and vibrations. Especially during extreme weather events like typhoons, air conditioning units must withstand enormous wind loads, placing extremely high demands on their structural strength and stability.

[0003] Traditional air conditioning units typically employ a standard panel structure, which has low rigidity and is ill-suited to withstand strong wind loads from extreme weather events such as typhoons at sea. Under strong winds, the unit panel is prone to deformation or damage, leading to decreased sealing performance and potentially causing damage to the internal structure of the equipment, thus affecting the stable operation of the air conditioning unit.

[0050] According to a second aspect of this disclosure, a marine air conditioning unit is proposed, including the marine air conditioning outdoor unit of the above embodiments.

[0051] Based on the above technical solutions, in the marine air conditioner outdoor unit of this disclosure, if a reinforcing component is provided on the inner wall of the windshield, the structural strength and rigidity of the windshield can be improved, preventing significant deformation of the windshield. If a reinforcing component is provided between the windshield and the front panel, support can be provided between the windshield and the outer casing, forming a stable frame structure. Therefore, by providing a reinforcing component, deformation of the windshield under wind loads can be prevented, thus preventing deformation of the various panels of the outer casing. This ensures the sealing performance of the outer casing and prevents damage to internal equipment that could affect the normal operation of the air conditioning system, effectively resisting strong wind loads from extreme weather such as typhoons at sea. Furthermore, the reinforcing structure being located on the inner side of the front panel does not affect the overall appearance of the marine air conditioner outdoor unit, requires no additional external space, and prevents external wind loads from acting on the reinforcing component to form a stress-bearing area.

[0085] Based on the embodiments disclosed above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

[0086] First, this disclosure proposes a marine air conditioning outdoor unit, such as Figures 1 to 12 As shown, in some embodiments, it includes:

[0087] The outer casing 100 includes a front panel 1, on which an air outlet is provided; and

[0088] The windshield 2 is installed on the outside of the front panel 1 and covers the area where the air outlet is located. The windshield 2 is provided with a ventilation opening for connecting the air outlet to the outside. The windshield 2 is provided with a reinforcing member on the inner side of the windshield 2 and / or between the windshield 2 and the front panel 1.

[0089] The outer casing 100 can be rectangular, and a grille can be provided on the front panel 1 to form an air outlet, such as... Figure 2As can be seen from the schematic diagram of the rear structure of the outdoor unit of the marine air conditioner, a mounting plate 30 can be installed on the rear side of the front panel 1. The mounting plate 30 has holes, such as circular holes, for installing the fan guide ring and the fan. The fan exhaust port can be directly opposite the air outlet.

[0090] The outer casing 100 may also include a first side panel 9, on which an air inlet 901 is provided. For example, multiple air inlets 901 may be provided, arranged in a rectangular array or other manner. The back of the outer casing 100 is open. During cooling, outside air enters through the air inlet 901 on the first side panel 9 and the back, exchanges heat with the condenser, and is then dissipated from the air outlet on the front panel 1 under the action of the fan. Although the wind deflector 2 covers the area where the air outlet is located, the airflow can be discharged to the outside through the ventilation openings provided on it.

[0091] In this embodiment, the marine air conditioning outdoor unit, by installing a wind deflector 2, prevents strong winds from directly blowing on the internal fan during strong winds, ensuring normal airflow performance and maintaining heat exchange efficiency. Since the wind deflector 2 is installed on the outermost side of the front of the outer casing 100, and cannot be designed as a closed structure due to airflow requirements, it needs to withstand significant wind loads in extreme weather. Installing reinforcing components on the inner wall of the wind deflector 2 improves its structural strength and rigidity, preventing significant deformation. Furthermore, installing reinforcing components between the wind deflector 2 and the front panel 1 provides support between the wind deflector 2 and the outer casing 100, forming a stable frame structure. Therefore, by installing reinforcing components, deformation of the wind deflector 2 under wind loads can be prevented, thus preventing deformation of the panels of the outer casing 100. This ensures the sealing performance of the outer casing 100 and prevents damage to internal equipment that could affect the normal operation of the air conditioning system. Consequently, it effectively resists strong wind loads from extreme weather conditions such as typhoons at sea. In addition, the reinforcement structure is located on the inside of the front panel 1, which does not affect the overall appearance of the marine air conditioner outdoor unit. It does not require additional external space and can also prevent external wind loads from acting on the reinforcement components to form a stress-bearing area.

[0092] In some embodiments, such as Figure 3 As shown, the windshield 2 includes a first plate 21 and two second plates 22. The first plate 21 is disposed opposite to the front panel 1 along the first direction x. The two second plates 22 are connected to both sides of the first plate 21 along the second direction y. The windshield 2 passes through both ends along the third direction z. The second direction y is perpendicular to the first direction x, and the third direction z is perpendicular to the first direction x and the second direction y.

[0093] The reinforcing components include a first transverse beam 24 and a first longitudinal beam 25. The first transverse beam 24 extends continuously along the inner sidewalls of the first plate 21 and the two second plates 22. The first longitudinal beam 25 is disposed on the inner sidewalls of the first plate 21 and / or the second plate 22 and passes through the first transverse beam 24.

[0094] The second plate 22 is angled relative to the first plate 21, for example, at a right angle or an obtuse angle. For instance, multiple sets of ventilation holes are spaced along a third direction z (i.e., the height direction) on the second plate 22, each set of ventilation holes potentially forming a rectangular area. The multiple sets of ventilation holes and the openings at both ends of the windshield 2 along the third direction z serve as ventilation openings for the windshield 2. The side edge of the second plate 22 extending along the third direction z has an outwardly bent first flange 23 for detachable connection to the front panel 1 via fasteners. The top and bottom edges of the first plate 21 and the second plate 22 have inwardly bent first flanges 23 for reinforcement.

[0095] One first transverse beam 24 may be provided, or multiple beams may be provided at intervals along the third direction z. The first transverse beam 24 may extend in a horizontal plane perpendicular to the third direction z. For example, the first transverse beam 24 may extend continuously on the inner sidewalls of the first plate 21 and the two second plates 22 to form a U-shape. At the connection between the first plate 21 and the second plate 22, the thickness of the first transverse beam 24 may be interrupted to facilitate bending. The portion of the first transverse beam 24 located on the second plate 22 may be located between adjacent groups of ventilation openings.

[0096] One or more first longitudinal beams 25 can be provided. The first longitudinal beams 25 can extend along a third direction z, directly extending to the top and bottom of the windshield 2. Figure 3 In this design, three first transverse beams 24 are spaced apart along the third direction z, and three first longitudinal beams 25 are located in the middle region of the first plate 21 along the second direction y (the left-right direction of the outer shell 100). This structure effectively increases the strength of the windshield 2 without significantly increasing its weight, achieving a balance between structural strength and lightweighting. For example, the first transverse beams 24 and the first longitudinal beams 25 can be connected by welding, and their cross-sections can be U-shaped with the openings facing either the first plate 21 or the second plate 22. In recent years, with increasingly stringent requirements for lightweighting and efficiency in ship design, how to achieve lightweighting and structural optimization of air conditioning units while ensuring their wind resistance has become a pressing technical challenge.

[0097] This embodiment forms a skeleton-type support structure by setting a first transverse beam 24 and a first longitudinal beam 25 on the inner side wall of the windshield 2, thereby improving the strength of the windshield 2 and preventing it from deforming under wind load. This prevents deformation of the panels of the outer shell 100, ensures the sealing performance of the outer shell 100, and prevents damage to internal equipment from affecting the normal operation of the air conditioning system. Thus, it can effectively resist strong wind loads brought by extreme weather such as typhoons at sea.

[0098] In some embodiments, such as Figure 3As shown, the reinforcing component also includes a first bracket 26, which includes a bottom arm 261 and two side arms 262. The bottom arm 261 is connected to the first transverse beam 24, the first end of each of the two side arms 262 is connected to both ends of the bottom arm 261, and the second end of each of the two side arms 262 is detachably connected to the front panel 1.

[0099] The side arms 262 and the bottom arm 261 are connected at an angle, forming a U-shaped structure with the first bracket 26. The bottom arm 261 can be mounted on the portion of the first transverse beam 24 located on the first plate 21, thereby positioning the first bracket 26 in a horizontal plane. The first bracket 26 can be welded to or detachably connected to the first transverse beam 24 by fasteners. Each of the two side arms 262 has a bent portion 264 at its second end, which can be bent outwards for detachable connection to the front panel 1 by fasteners. To improve the rigidity of the first bracket 26, a second flange 263 can be provided on the edge of the bottom arm 261 and / or the side arm 262.

[0100] For example, such as Figure 3 As shown, three first transverse beams 24 are spaced apart along the third direction z. The middle first transverse beam 24 can be located in the middle area of ​​the windshield 2 along the third direction z. The first longitudinal beam 25 is located in the middle area of ​​the first plate 21 along the second direction y (left and right direction of the outer shell 100). The first bracket 26 can be fixed on the middle first transverse beam 24 and is located in the middle area of ​​the first plate 21 along the second direction y.

[0101] This embodiment provides support between the windshield 2 and the outer casing 100 by setting a first bracket 26 between the first plate 21 and the front panel 1, forming a stable frame structure between them. This helps maintain a constant distance between the windshield 2 and the front panel 1 and optimizes stress distribution. This prevents the windshield 2 from deforming under wind loads, thus preventing deformation of the panels of the outer casing 100. It ensures the sealing performance of the outer casing 100 and prevents damage to internal equipment that could affect the normal operation of the air conditioning system. Therefore, it effectively resists strong wind loads from extreme weather such as typhoons at sea. Furthermore, the first bracket 26 has a simple structure and small footprint, enabling a lightweight design for the windshield 2. During installation, the first bracket 26 can be installed on the windshield 2 and the front panel 1 first, and then the resulting assembly can be used to assemble the outer casing 100. This allows for convenient placement of the first bracket 26 between the windshield 2 and the front panel 1.

[0102] Furthermore, the windshield 2 is simultaneously equipped with a first transverse beam 24, a first longitudinal beam 25, and a first support 26. The first transverse beam 24 and the first longitudinal beam 25 form a cross-frame structure, providing rigid support for the first panel 21 and the second panel 22, effectively improving the overall stiffness of the panel. Moreover, the first support 26 not only provides auxiliary support for the transverse and longitudinal support structures but also optimizes stress distribution and enhances structural stability. These two reinforcing components work together to form a complete force transmission system, significantly reducing the amount of panel deformation caused by wind loads and ensuring the stability of the structure under dynamic loads.

[0103] In some embodiments, such as Figure 3 As shown, multiple first transverse beams 24 are spaced apart along the third direction z, and the spacing L1 between adjacent first transverse beams 24 satisfies:

[0104]

[0105] Where m is the number of first transverse beams 24 and is odd, h is the dimension of the first transverse beam 24 along the third direction z, and H1 is the dimension of the windshield 2 along the third direction z; and / or

[0106] The length L2 of the bottom arm 261 along the second direction y satisfies: L2 ≥ (H2) / 2, where H2 is the dimension of the first plate 21 along the second direction y; and / or

[0107] The included angle e between the bottom arm 261 and the side arm 262 satisfies: 90°≤e≤135°.

[0108] The windshield 2 in this embodiment has a skeleton support structure. Appropriate parameters can be selected according to its size and strength requirements. By setting an appropriate spacing between adjacent first transverse beams 24, both the strength requirements of the windshield 2 and the lightweight design can be guaranteed. By designing the length L2 of the bottom arm 261 along the second direction y to be at least half the dimension of the first plate 21 along the second direction y, the distance between the two side arms 262 can be increased as much as possible, so that the first bracket 26 can play a more stable supporting role, optimize the rigidity of the frame structure formed between the windshield 2 and the front panel 1, and reduce the amount of deformation. By designing the included angle e between the bottom arm 261 and the side arm 262 to be a right angle or an obtuse angle less than 135°, the support strength of the first bracket 26 can be improved, and the size limit of the windshield 2 along the second direction y can be met.

[0109] In some embodiments, such as Figure 1 and Figure 4 As shown, the housing 100 also includes a maintenance plate 3, which is arranged side by side with the front panel 1 along the second direction y.

[0110] The inspection plate 3 includes a base plate 31, a second transverse beam 32 and a second longitudinal beam 33. The second transverse beam 32 is disposed on the inner sidewall of the base plate 31, and the second longitudinal beam 33 is disposed on the inner sidewall of the base plate 31 and passes through the second transverse beam 32.

[0111] The inspection plate 3 and the front panel 1 together form the front wall of the housing 100. The windshield 2 can cover the front panel 1. The inspection plate 3 is located on the outside of the windshield 2 along the second direction y. The area behind the inspection plate 3 is used to install the compressor. The inspection plate 3 can be detachably connected to the front panel 1 by fasteners to be closed in the working state and removed in the maintenance state for maintenance of the internal equipment of the housing 100.

[0112] The second transverse beam 32 can extend along the second direction y, and can be one or multiple beams spaced apart along the third direction z. The second longitudinal beam 33 can extend along the third direction z, and can be one or multiple beams spaced apart along the second direction y. Figure 4 As shown, the width dimension of the substrate 31 along the second direction y is smaller than the height dimension along the third direction z. Three second transverse beams 32 are provided, and one second longitudinal beam 33 is provided and located in the middle region of the substrate 31 along the second direction y.

[0113] For example, the second transverse beam 32 and the second longitudinal beam 33 can be connected to the substrate 31 by fasteners, or the second transverse beam 32 and the second longitudinal beam 33 can be welded to form an integrated skeleton support structure and connected to the substrate 31 by welding.

[0114] This embodiment takes into account that the inspection plate 3 is located in the front area of ​​the outer shell 100. When the ship is sailing at sea, the inspection plate 3 is also in the windward area and is subjected to a large wind load. By setting the second transverse beam 32 and the second longitudinal beam 33 on the inner wall of the base plate 31, a skeleton support structure can be formed, thereby improving the strength of the inspection plate 3 itself and providing effective rigid support to prevent the inspection plate 3 from undergoing large deformation under the action of wind load, so as to avoid deformation of other panels of the outer shell 100. This can ensure the sealing performance of the outer shell 100 and prevent damage to internal equipment from affecting the normal operation of the air conditioning system. Thus, it can effectively resist the strong wind load brought by extreme weather such as typhoons at sea.

[0115] In some embodiments, such as Figure 1 and Figure 2 As shown, the outer casing 100 also includes a first side plate 9, which is disposed on one side of the front panel 1 along the second direction y. Figure 1 In the middle, from the front side perspective, the first side panel 9 is located on the left side of the front panel 1;

[0116] like Figure 5 and Figure 6As shown, the first side plate 9 includes a first main plate 90, a third transverse beam 93 and a third longitudinal beam 94. The first main plate 90 is provided with an air inlet 901. The third transverse beam 93 and the third longitudinal beam 94 are both located on the inner side wall of the first main plate 90 in the area outside the air inlet 901. The third longitudinal beam 94 passes through the third transverse beam 93.

[0117] For example, the first side plate 9 is provided with multiple air inlets 901, and the multiple air inlets 901 can be arranged in multiple groups at intervals along the third direction z. Each group of air inlets 901 can be arranged in a rectangular array or other manner. The third transverse beam 93 can be provided between two adjacent groups of air inlets 901 and extend along the second direction y, and the third longitudinal beam 94 can be provided between two adjacent columns of air inlets 901 and extend along the third direction z. Figure 5 As shown, the first main body plate 90 is divided into three regions in the second direction y and the third direction z.

[0118] For example, the third transverse beam 93 and the third longitudinal beam 94 can be connected to the first main body plate 90 by fasteners, or the third transverse beam 93 and the third longitudinal beam 94 can be welded to form an integrated frame support structure and connected to the first main body plate 90 by welding.

[0119] This embodiment forms a skeleton-like support structure by setting a third transverse beam 93 and a third longitudinal beam 94 on the inner side wall of the first main body plate 90, thereby improving the strength of the first side plate 9 and providing effective rigid support. This prevents the first side plate 9 from undergoing large deformation under wind load, so as to avoid deformation of other panels of the outer shell 100. It can ensure the sealing performance of the outer shell 100 and prevent damage to internal equipment from affecting the normal operation of the air conditioning system. Thus, it can effectively resist strong wind loads brought by extreme weather such as typhoons at sea.

[0120] In some embodiments, such as Figure 6 As shown, the first main body plate 90 has an L-shaped bent edge 902 on the side of the front panel 1 along the first direction x. The first side plate 9 also includes a plurality of first reinforcing ears 91. The plurality of first reinforcing ears 91 are arranged in the space enclosed by the L-shaped bent edge 902 and the first main body plate 90, and are spaced apart along the third direction z, which is perpendicular to the second direction y.

[0121] The L-shaped bend 902 includes a first connecting strip and a second connecting strip connected at an angle. The first connecting strip is connected to the side edge of the first main body plate 90 and extends inward. The first connecting strip has mounting holes for connecting the first side plate 9 to the front panel 1 using fasteners. The second connecting strip is connected to the side of the first connecting strip away from the first main body plate 90 and extends inward, thus forming a space between the L-shaped bend 902 and the first main body plate 90. For example, Figure 6 It has five first reinforcing lugs 91.

[0122] This embodiment facilitates the connection between the first side plate 9 and the front panel 1 by providing an L-shaped bent edge 902 on one side of the first main body plate 90, thereby improving the connection strength. Since the L-shaped bent edge 902 is cantilevered, multiple first reinforcing lugs 91 are provided at intervals between the L-shaped bent edge 902 and the first main body plate 90 to prevent deformation of the L-shaped bent edge 902, thus improving the connection rigidity between the first side plate 9 and the front panel 1. Furthermore, by providing first reinforcing lugs 91 at the edge of the first side plate 9 and providing a third transverse beam 93 and a third longitudinal beam 94 on the large surface, the overall structure of the first side plate 9 can be effectively strengthened.

[0123] In some embodiments, the first main body plate 90 has an L-shaped bent edge 902 on the side away from the front panel 1 along the first direction x. The first side plate 9 also includes a reinforcing column 95 with an L-shaped cross-section. The reinforcing column 95 is disposed in the space enclosed by the L-shaped bent edge 902 and the first main body plate 90, and extends along the third direction z. Both ends of the reinforcing column 95 along the third direction z are closed by connecting plates. The outer shell 100 also includes a top plate 7 and a bottom plate 8. The two connecting plates are respectively connected to the top plate 7 and the bottom plate 8. The second direction y is perpendicular to the first direction x, and the third direction z is perpendicular to the first direction x and the second direction y.

[0124] The L-shaped bend 902 includes a first connecting strip and a second connecting strip connected at an angle. The first connecting strip is connected to the side edge of the first main body plate 90 and extends inward. The first connecting strip is provided with mounting holes for connecting the first side plate 9 to the rear plate of the outer casing 100 by fasteners. The second connecting strip is connected to the side of the first connecting strip away from the first main body plate 90 and extends inward. Thus, a space is formed between the L-shaped bend 902 and the first main body plate 90.

[0125] Furthermore, the inner edge of the second connecting strip of the L-shaped bend edge 902 is provided with an extension edge 903, which extends along the second direction y in a direction away from the first main body plate 90 for installation with other plates.

[0126] Optionally, the reinforcing column 95 also has an L-shaped cross-section. The reinforcing column 95 includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is attached to the first main body plate 90, and the second reinforcing plate is attached to the first connecting strip. The top and bottom of the reinforcing column 95 are both closed by connecting plates, which are connected to the top plate 7 and the bottom plate 8 respectively. For example, the reinforcing column 95 can be connected to the first main body plate 90 by two fasteners.

[0127] Optionally, the thickness t3 of the reinforcing column 95, the thickness t2 of the first reinforcing lug 91, and the thickness t1 of the first main plate 90 should satisfy t3≥t1 and t2≥t1. This will better achieve the reinforcing effect.

[0128] Since the area formed by the L-shaped bend 902 of the extended edge 903 is narrow in the first direction x, it is inconvenient to install the first reinforcing lug 91. Therefore, a reinforcing column 95 is installed. For the L-shaped bend 902 on the other side, installing multiple first reinforcing lugs 91 can reduce weight while meeting strength requirements.

[0129] This embodiment, by providing an L-shaped bent edge 902 on the other side of the first main body plate 90, facilitates the connection between the first side plate 9 and the rear plate of the outer shell 100, thereby improving the connection strength. Since the L-shaped bent edge 902 is cantilevered, a reinforcing column 95 is provided between the L-shaped bent edge 902 and the first main body plate 90 to prevent deformation of the L-shaped bent edge 902, thus improving the connection rigidity between the first side plate 9 and the rear plate of the outer shell 100. Furthermore, since the top and bottom of the reinforcing column 95 are both enclosed by connecting plates, it can be easily connected to the top plate 7 and the bottom plate 8, improving the strength of the connection and thus enhancing the overall rigidity of the outer shell 100.

[0130] Furthermore, by setting reinforcing columns 95 at the edge of the first side plate 9 and setting third transverse beams 93 and third longitudinal beams 94 on the large surface, the overall structure of the first side plate 9 can be strengthened more effectively.

[0131] In addition, the third transverse beam 93, the third longitudinal beam 94, the first reinforcing lug 91, and the reinforcing column 95 can effectively improve the overall bending stiffness of the first side plate 9 while ensuring lightweight design, optimize stress distribution, and significantly reduce the deformation of the first side plate 9 under wind load.

[0132] In some embodiments, such as Figure 6 and Figure 7 As shown, the marine air conditioner outdoor unit also includes a condenser, and the first side plate 9 also includes a support frame 92, which includes:

[0133] The third plate 921 is connected to the area of ​​the front panel 1 along the first direction x on the inner wall of the first main plate 90, and extends along the third direction z, which is perpendicular to the second direction y.

[0134] The fourth plate 922 is angled to the inner side of the third plate 921 and extends along the second direction y in a direction away from the first main plate 90. Multiple mounting holes 923 are spaced along the third direction z on the fourth plate 922 for mounting the first end of the condenser; and

[0135] Multiple fifth plates 924 are connected to the fourth plate 922 on the side away from the first main plate 90 along the second direction y and are spaced apart along the third direction z. The multiple fifth plates 924 are used to install support plates for protecting the condenser in the transport state, and the support plates are used to be removed in the use state.

[0136] The third plate 921 is located on the side of the first reinforcing lug 91 away from the L-shaped bend edge 902 along the first direction x. The third plate 921 can be detachably installed on the first main body plate 90 using fasteners. The fourth plate 922 is vertically connected to the inner side of the third plate 921 and extends along the second direction y in a direction away from the first main body plate 90. The mounting hole 923 on the fourth plate 922 can be an elongated hole extending along the third direction z, used to support the U-shaped tube of the condenser. The fourth plate 922 can extend along the entire height of the first main body plate 90. Multiple fifth plates 924 are located in the same plane as the fourth plate 922. The fifth plates 924 are also provided with mounting holes 923, which can be elongated holes extending along the third direction z.

[0137] Optionally, the top and bottom of the fourth plate 922 extend beyond the end of the third plate 921, and the bottom of the fourth plate 922 is provided with a bending plate for fixing to the bottom plate 8 of the housing 100.

[0138] This embodiment provides a support frame 92 on the inner side of the first main body plate 90. The support frame 92 and the mounting plate 62 in the partition assembly 6 mentioned in subsequent embodiments can be used to install the two ends of the condenser, and the support frame 92 can also strengthen the first side plate 9, improving the overall structural strength. In addition, the support frame 92 includes multiple fifth plates 924 that can be used to install bracket guards when the marine air conditioner outdoor unit needs to be transported, and can be removed when in use.

[0139] In some embodiments, such as Figure 2 As shown, the marine air conditioner outdoor unit also includes a partition assembly 6, a fan, a condenser, and a compressor. The partition assembly 6 is located inside the outer casing 100 and divides the inner casing 100 into a first region and a second region along the second direction y. The first region communicates with the air outlet and is used to accommodate the fan and condenser, while the second region is used to accommodate the compressor. It may also further accommodate a gas-liquid separator and related connecting pipes. Figure 8 , Figure 9 and Figure 10 The separator component 6 includes:

[0140] Partition 61; and

[0141] Mounting plate 62 is connected side-by-side to the side of partition 61 away from front panel 1 along the first direction x. Mounting plate 62 is used to mount the second end of condenser. The first direction x is perpendicular to the second direction y.

[0142] For example, partition 61 is connected to mounting plate 62 by a plurality of fasteners spaced at intervals along the third direction z, such as four fasteners.

[0143] For example, the overlapping portions of the mounting plate 62 and the partition plate 61 are connected by fasteners.

[0144] Specifically, the support frame 92 of the first side plate 9 is located at the front of the outer casing 100 and is used to install the first end of the condenser; the mounting plate 62 is located at the rear of the outer casing 100 and is used to install the second end of the condenser. The condenser has a bent L-shaped structure so that the L-shaped condenser can be installed on the support frame 92 and the mounting plate 62.

[0145] This embodiment, by providing a partition component 6 inside the housing 100, which can be arranged perpendicular to the second direction y, can divide the internal area of ​​the housing 100 into a first area and a second area. The first area is formed between the partition component 6, the front panel 1, and the first side panel 9. A second side panel 4 is arranged on the opposite side of the first side panel 9 along the second direction y. The second area is formed between the inspection panel 3, the second side panel 4, and the partition component 6. This separates the second area for accommodating the compressor from the first area for accommodating the condenser and the fan, forming an independent space, preventing the operation of the compressor from affecting the condenser and the fan, and defining the first area as an air duct.

[0146] In some embodiments, such as Figure 9 As shown, the partition 61 includes:

[0147] Second main body plate 610;

[0148] Multiple fourth transverse beams 611 are spaced apart along a third direction z on the sidewall of the second main body plate 610 facing the first region, the third direction z being perpendicular to the first direction x and the second direction y; and

[0149] The fourth longitudinal beam 612 is provided on the side wall of the second main body plate 610 facing the first region, and extends downward from at least the lowest fourth transverse beam 611 to the bottom of the second main body plate 610, for connection with the bottom plate 8 of the outer casing 100.

[0150] Optionally, the fourth transverse beam 611 extends along the first direction x, and the fourth longitudinal beam 612 extends along the third direction z. For example, there are two fourth transverse beams 611, and the fourth longitudinal beam 612 extends from the lower fourth transverse beam 611 to the bottom of the second main body plate 610 to form a T-shaped reinforcing beam in the lower region. Wherein, the dimension of the partition plate 61 along the third direction z is k1, the distance between the upper fourth transverse beam 611 and the top of the second main body plate 610 is k2, then the distance k3 between the lower fourth transverse beam 611 and the bottom of the second main body plate 610 satisfies: k3=(k1) / 4.

[0151] This embodiment, by setting multiple fourth transverse beams 611 and fourth longitudinal beams 612, can improve the ability of the partition 61 to resist lateral bending. The fourth longitudinal beams 612 can provide effective support for the partition 61 at the bottom, further improving the rigidity of the partition 61. Moreover, the connection between the fourth longitudinal beams 612 and the bottom plate 8 is conducive to forming a stable frame structure. In addition, the fourth longitudinal beams 612 are preferably set at the bottom to minimize the weight of the partition 61, realizing a lightweight design for the marine air conditioning outdoor unit.

[0152] In some embodiments, such as Figure 10 As shown, the partition 61 includes:

[0153] The second main body plate 610 has a first bent edge and a second bent edge on both sides along the first direction x, respectively, facing the second region, and the obtuse angle between the first bent edge and the second main body plate 610 is smaller than the obtuse angle between the second bent edge and the second main body plate 610.

[0154] Multiple reinforcing plates 613 are spaced apart along a third direction z in the connection area between the first bent edge and the second main body plate 610, with the third direction z perpendicular to the first direction x and the second direction y; and

[0155] Multiple reinforcing beams 614 are spaced at intervals along the third direction z in the connection area between the second bending edge and the second main body plate 610.

[0156] At the first bend, the two adjacent sides of the reinforcing plate 613 are connected to the second main plate 610 and the first bend, respectively. Since the second bend needs to be connected to the mounting plate 62, the angle between the second bend and the second main plate 610 is relatively gentle to facilitate overlapping connection and fixation with fasteners. Therefore, it is difficult to install the reinforcing plate 613. The reinforcing beam 614 can be horizontally installed, and its cross-section can be C-shaped. The open side of the reinforcing beam 614 is connected to the second main plate 610, and one end is connected to the second bend. For example, the reinforcing plate 613 and the reinforcing beam 614 can be connected by welding. Figure 10 Four are set in each section. The reinforcing plate 613 and the reinforcing beam 614 are set on the side of the second main plate 610 facing the second region.

[0157] This embodiment provides reinforcing plates 613 and reinforcing beams 614 on both sides of the second main body plate 610, which can locally strengthen the edge area of ​​the second main body plate 610, improve the connection strength between the partition plate 61 and other plates, and make the partition plate 61 and the outer shell 100 form a stable frame structure.

[0158] In some embodiments, such as Figure 10 and Figure 11As shown, the housing 100 also includes a maintenance plate 3 and a second side plate 4. The maintenance plate 3 and the front panel 1 are arranged side by side along the second direction y, and the second side plate 4 is arranged along the second direction y on the side of the maintenance plate 3 away from the front panel 1.

[0159] A second support 63 is provided between the partition 61 and the second side plate 4. The second support 63 includes two first beams 631 and a second beam 632. The two first beams 631 are respectively connected to the partition 61 and the second side plate 4, and the two ends of the second beam 632 are respectively connected to the two first beams 631.

[0160] For example, the first beam 631 can extend along a third direction z, and its cross-section can be C-shaped. The second beam 632 extends along a second direction y, and its cross-section can be L-shaped, achieving a lightweight design. The second support 63 can be located near the lower part of the second main body plate 610. A compressor is installed below the second support 63, and a gas-liquid separator is installed above the second support 63. The second support 63 is located precisely in the space between the compressor and the gas-liquid separator. For example, the first beam 631 can be welded to the partition plate 61 or the second side plate 4, and the first beam 631 and the second beam 632 can be connected by fasteners for easy installation.

[0161] This embodiment provides stable support between the partition 61 and the second side plate 4 by setting an I-shaped second bracket 63 between the partition 61 and the second side plate 4, thereby forming a stable frame structure between them. This increases the mutual reinforcement between the outer shell 100 and the partition assembly 6, and reduces the deformation of each panel of the outer shell 100 under wind load.

[0162] In some embodiments, the second bracket 63 is located on the front side of the compressor along the first direction x, that is, the second bracket 63 is located in the area of ​​the partition 61 near the front panel 1 along the first direction x.

[0163] In this embodiment, the second bracket 63 is located in the area in front of the compressor, which can avoid interference between the second bracket 63 and the compressor's piping.

[0164] In some embodiments, such as Figure 1 and Figure 11 As shown, the housing 100 also includes a maintenance plate 3 and a second side plate 4. The maintenance plate 3 and the front panel 1 are arranged side by side along the second direction y, and the second side plate 4 is arranged along the second direction y on the side of the maintenance plate 3 away from the front panel 1.

[0165] The second side plate 4 includes a side plate portion 4A and a rear plate portion 4B connected at an angle, as well as a reinforcing member 42. The side plate portion 4A is located on the side, and the rear plate portion 4B is located at the rear. The reinforcing member 42 includes two fifth transverse beams 421 and a bent beam 422. The two fifth transverse beams 421 are respectively connected to the inner sidewalls of the side plate portion 4A and the rear plate portion 4B, and the two ends of the bent beam 422 are respectively connected to the two fifth transverse beams 421.

[0166] The side plate 4A and the rear plate 4B are vertically connected. The partition assembly 6 is disposed opposite to the side plate 4A along the second direction y. The partition assembly 6, the inspection plate 3, the side plate 4A, and the rear plate 4B enclose a second area for accommodating the compressor. The cross-section of the second side plate 4 is L-shaped, so a reinforcing member 42 is provided to improve its strength. One reinforcing member 42 may be provided, or multiple reinforcing members 42 may be provided at intervals along the third direction z.

[0167] Specifically, the reinforcing member 42 includes two fifth transverse beams 421 and a bent beam 422. The fifth transverse beams 421 can extend in the horizontal plane, have a C-shaped cross-section to achieve a lighter weight, and have an opening facing the side plate portion 4A or the rear plate portion 4B, which can be welded. The bent beam 422 has a flange on at least one side along its own width direction to increase strength. The bent beam 422 includes a first section 422A and two second sections 422B. The two second sections 422B are detachably connected to the two fifth transverse beams 421 by fasteners for easy installation. The first section 422A is connected to the two second sections 422B, and the second sections 422B and the first section 422A form an obtuse angle.

[0168] like Figure 8 As shown, there are three reinforcing members 42. The uppermost reinforcing member 42 is connected to the fifth transverse beam 421 on the side plate 4A, which is shorter than the other fifth transverse beams 421, so as to leave installation space for the adjacent electrical box.

[0169] like Figure 11 As shown, the fifth transverse beam 421 of different lengths can be selected within the allowable space according to the stiffness requirements of the second side plate 4. However, the length x1 of the fifth transverse beam 421 and the width x2 of the side plate part 4A or the rear plate part 4B should satisfy x1≥(x2) / 4.

[0170] like Figure 8 As shown, the side plate 4A is provided with a third flange on the side away from the second plate B, which is used to connect with the inspection plate 3. Multiple second reinforcing lugs 43 are provided at intervals along the third direction z in the area between the third flange and the side plate 4A to prevent the third flange from deforming.

[0171] This embodiment, by setting an L-shaped second side plate 4, forms an area for accommodating the compressor. By setting a reinforcing member 42, the overall rigidity of the second side plate 4 is increased, thereby improving the overall rigidity of the outer casing 100 and preventing deformation under strong wind loads. Moreover, the fifth transverse beam 421 can support the panel of the second side plate 4 while fixing the bending beam 422. The double-bend structure of the bending beam 422 can connect and strengthen the side plate portion 4A and the rear plate portion 4B, optimize the force transmission path, and improve the overall strength and reliability of the second side plate 4.

[0172] Furthermore, an I-shaped second bracket 63 is provided between the side plate 4A and the partition 61, which provides stable support between the partition 61 and the second side plate 4, forming a stable frame structure between them. This increases the mutual reinforcement between the outer shell 100 and the partition assembly 6, reducing the deformation of the panels of the outer shell 100 under wind loads. The second bracket 63 can be located below the reinforcing member 42 to provide space for the compressor, gas-liquid separator, and their connected piping components.

[0173] In some embodiments, such as Figure 2 As shown, the outer casing 100 also includes an inspection plate 3, a first side plate 9, a second side plate 4, a top plate 7, and a bottom plate 8. The inspection plate 3 and the front panel 1 are arranged side by side along the second direction y. The first side plate 9 is arranged on one side of the front panel 1 along the second direction y. The second side plate 4 includes a side plate portion 4A and a rear plate portion 4B connected at an angle. The side plate portion 4A is connected to the inspection plate 3 and is located on the side, while the rear plate portion 4B is located at the rear.

[0174] The top plate 7 and the bottom plate 8 are connected at the rear of the outer shell 100 by a first connecting beam 10, and the rear plate 4B is connected to the first side plate 9 by a plurality of second connecting beams 20 spaced apart along the third direction z.

[0175] The first connecting beam 10 can be provided in a single manner to reduce the impact on the rear air intake of the outer casing 100. It also has a larger width to provide better support between the top plate 7 and the bottom plate 8. Furthermore, weight-reducing grooves can be provided on the first connecting beam 10 to achieve lightweight design while increasing support. The first connecting beam 10 can be located in the middle region along the second direction y between the rear plate portion 4B and the first side plate 9. Optionally, multiple first connecting beams 10 can be provided at intervals along the second direction y.

[0176] The rear plate 4B is connected to the first side plate 9 by a plurality of second connecting beams 20 spaced at intervals along the third direction z, for example, three beams are provided, and the two ends of the second connecting beams 20 can be detachably connected by fasteners.

[0177] In this embodiment, considering that the rear of the outer casing 100 needs to be air-intaked, no panel is provided for sealing. The rear plate portion 4B of the second side plate 4 is connected to the first side plate 9 only by the first connecting beam 10 and the second connecting beam 20. This can ensure the overall rigidity of the outer casing 100, prevent deformation when subjected to large wind loads, and also leave a large air intake area.

[0178] In some embodiments, such as Figure 2 and Figure 12 As shown, the marine air conditioner outdoor unit also includes a rear bracket 5, which includes:

[0179] The longitudinal frame 53 has a mounting beam 52 on its front side, which is connected to the rear side of the outer shell 100. The top of the longitudinal frame 53 has a fixing frame 51, which is connected to the top plate 7 of the outer shell 100.

[0180] The transverse frame 54, connected to the bottom of the longitudinal frame 53, is used for connection to the surface to be installed; and

[0181] Two diagonal supports 55 are connected to the longitudinal frame 53 and the transverse frame 54 on both sides along the second direction y.

[0182] The longitudinal frame 53 and the transverse frame 54 can be designed as rectangular frame structures. The transverse frame 54 can be detachably connected to the surface to be installed using fasteners located at the four corners.

[0183] A mounting beam 52 is provided on the front side of the longitudinal frame 53. The mounting beam 52 can be located in the middle area along the third direction z at the rear of the housing 100. The mounting beam 52 is used to fix the rear bracket 5 to the rear of the housing 100. Both ends of the mounting beam 52 can be detachably mounted to the longitudinal frame 53 by fasteners. The mounting beam 52 is then detachably mounted to the first side plate 9 and the second side plate 4 by fasteners.

[0184] A mounting bracket 51 is provided on the top side of the longitudinal frame 53 facing the housing 100. The mounting bracket 51 can extend along the entire width of the longitudinal frame 53 and is installed on the longitudinal frame 53 by fasteners located on both sides. The mounting bracket 51 is then connected to the top plate 7 by fasteners.

[0185] The top of the diagonal brace 55 is lower than the top of the longitudinal frame 53, and the bottom of the diagonal brace 55 is recessed inward relative to the outer end of the transverse frame 54. The two ends of the diagonal brace 55 can be welded to the longitudinal frame 53 and the transverse frame 54 to form an integral structure, creating a stable triangular structure between the longitudinal frame 53 and the transverse frame 54. For example, the diagonal brace 55 can be a diagonal beam, etc.

[0186] For example, the height of the longitudinal frame 53 along the third direction z is n1, and the distance between the top of the diagonal support 55 and the top of the longitudinal frame 53 is n2, where n1 and n2 satisfy n2 / n1≤1 / 4. The included angle between the diagonal support 55 and the longitudinal frame 53 is r, where r≥30°.

[0187] This embodiment, by providing a rear support 5 at the rear of the housing 100, serves as an auxiliary support and installation mechanism, making the installation of the housing 100 more stable. It also reduces the likelihood of backward tilting forces when subjected to wind loads at the front, preventing deformation of the housing 100. Furthermore, the rear support 5 can be easily installed at the rear of the housing 100 via the fixing frame 51 and the mounting beam 52, and is easy to disassemble. Additionally, the longitudinal frame 53 and transverse frame 54 of the fixing frame 51 form a stable triangular structure through diagonal supports 55, providing stable and reliable support. The transverse frame 54's installation on the mounting surface further enhances connection reliability. Even in extreme weather conditions such as typhoons, this improves the stability of the marine air conditioning outdoor unit installation, effectively resisting strong wind loads from typhoons and other extreme weather events at sea.

[0188] In some embodiments, such as Figure 1 As shown, the bottom surface of the housing 100 is provided with two support beams 40. The two support beams 40 are spaced apart along the second direction y and extend along the first direction x. The first direction x is perpendicular to the second direction y. The support beams 40 are used to connect with the surface to be installed.

[0189] The end of the support beam 40 may extend beyond the front panel 1 for easy connection to the surface to be installed via fasteners. For example, the cross-section of the support beam 40 may be zigzag-shaped, with two folded edges on the sides connected to the base plate 8, for example, by welding, and the middle part connected to the surface to be installed.

[0190] To install the support beam 40, the lower surface of the base plate 8 should be higher than the lower surface of the transverse frame 54. If the surface to be installed is entirely flat, the lower surface of the support beam 40 can be flush with the lower surface of the transverse frame 54.

[0191] This embodiment achieves stable and reliable installation of the marine air conditioner outdoor unit through the cooperation of the support beam 40 at the bottom of the outer casing 100 and the transverse frame 54 of the rear bracket 5, ensuring the reliability of the overall installation under extreme weather conditions such as typhoons and strong winds.

[0192] In some specific embodiments, such as Figure 1 and Figure 2As shown, the housing 100 includes a front panel 1, an inspection panel 3, a second side panel 4, a first side panel 9, a top panel 7, a bottom panel 8, and a windshield 2. The front panel 1 and the inspection panel 3 are spaced apart along the second direction y. The first side panel 9 is connected to the side of the front panel 1 away from the inspection panel 3 along the second direction y. The first side panel 9 can be arranged perpendicular to the second direction y. The second side panel 4 includes a side panel portion 4A and a rear panel portion 4B connected at an angle. The side panel portion 4A is arranged opposite to the first side panel 9 along the second direction y and is located on the side. The rear panel portion 4B is located at the rear. The windshield 2 is installed on the front side of the front panel 1.

[0193] By providing the reinforcing structure of the aforementioned embodiment on each panel of the outer casing 100 and the windshield 2, the overall rigidity can be improved, the deformation of the marine air conditioner outdoor unit under strong wind load can be reduced, and the structural and operational reliability can be ensured. Figure 13 and Figure 14 The figures shown are simulation cloud diagrams of stress and displacement of a typical marine air conditioner outdoor unit under strong wind load. Figure 14 The diagram shows simulated stress and displacement cloud maps of marine air conditioning outdoor units under strong wind loads according to some embodiments of this disclosure. By comparing the simulated cloud maps, it can be seen that after using a reinforced structure, the maximum stress under strong wind loads in the embodiments of this disclosure decreases from 1419 MPa to 472 MPa, a reduction of 947 MPa. The maximum displacement decreases from 73.1 mm to 5.6 mm, a reduction of 67.5 mm.

[0194] pass Figure 13 and Figure 14 It can be seen that during the use of the marine air conditioner outdoor unit, the windshield 2 bears the greatest stress and displacement under wind load. Therefore, structural reinforcement of the windshield 2 has a significant effect on relieving stress and reducing displacement. Figure 15 and Figure 16 It can be seen that after setting the first transverse beam 24 and the first longitudinal beam 25, the windshield 2 is divided into multiple smaller areas, which enhances its ability to resist wind loads.

[0195] This disclosure addresses the problem that conventional marine air conditioning outdoor units are prone to damage and disruption of normal operation under strong wind loads such as typhoons at sea due to insufficient panel structural rigidity. It proposes a high-rigidity marine wind-resistant air conditioning outdoor unit that significantly improves panel rigidity and wind resistance without significantly increasing equipment weight, thus meeting the needs of extreme marine environments and solving the reliability issues of existing air conditioning outdoor units in strong wind conditions. This ensures stable operation under extreme wind loads. While ensuring high rigidity performance, it also meets the lightweight design requirements of marine equipment, effectively solving the equipment safety problem in strong wind environments. Specifically, by incorporating optimized reinforcing structures within each panel, the bending and shear resistance of the panels can be significantly improved, enabling them to effectively resist strong wind loads from extreme weather such as typhoons. Simultaneously, this design also considers lightweight design and ease of installation and maintenance, providing an effective solution for improving the performance of marine air conditioning units.

[0196] Secondly, this disclosure proposes a marine air conditioning unit, including the marine air conditioning outdoor unit of the above embodiment. Furthermore, the marine air conditioning unit also includes a marine air conditioning indoor unit.

[0197] The windshield 2 of the marine air conditioner outdoor unit in this embodiment can prevent the windshield 2 from deforming under wind load by setting a reinforcing component between the inner side wall and / or the front panel 1, which would cause deformation of each panel of the outer casing 100. This ensures the sealing performance of the outer casing 100 and prevents damage to the internal equipment of the outer casing 100 from affecting the normal operation of the air conditioning system. As a result, it can effectively resist the strong wind load brought by extreme weather such as typhoons at sea, thus making the working performance of the marine air conditioning unit stable and reliable.

Specific embodiments have been used to illustrate the principles and implementation methods of this disclosure. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this disclosure. It should be noted that those skilled in the art can make various improvements and modifications to this disclosure without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this disclosure.
