Description

Technical Field

[0001] The invention relates to the technical field of air conditioning equipment, and in particular to an air handling cabinet. Background Art

[0002] The air handling unit mainly relies on the rotation of the fan to drive the indoor (outdoor) air to exchange heat with the internal coil of the unit, and filter the impurities in the air to control the outlet temperature and air volume to maintain the indoor temperature, humidity and air cleanliness. Since the full air cabinet is often installed in the machine room or outdoors, it has the characteristics of large air supply volume, multi-functional regulation of the whole house, and long-term operation.

[0003] The air handling cabinets currently available on the market generally have problems such as inconvenient connection, loud noise, small cooling capacity, poor electrical safety, and short filter life. Summary of the invention

[0004] In view of this, the present invention provides an air handling cabinet to solve some or all of the problems existing in the above-mentioned air handling cabinets.

[0005] In a first aspect, the present invention provides an air handling cabinet, the air handling cabinet comprising:

[0006] The housing has an air duct arranged inside. Along the wind flow direction, the air duct includes a return air duct, a heat exchange duct and an air supply duct arranged in sequence. The return air duct and the air supply duct are arranged side by side and in parallel, so that the air duct has a U-shaped structure.

[0007] A filter module is arranged in the return air channel;

[0008] A heat exchange module is arranged in the heat exchange channel;

[0009] A fan module is arranged in the air supply channel;

[0010] The silencer module is arranged in the air supply channel; and along the wind flow direction, the silencer module is located downstream of the fan module.

[0011] Beneficial effects: The embodiment of the present invention sets the air duct as a U-shaped structure, so that the air flow path inside the wind cabinet is more reasonable, which reduces the resistance of air flow to a certain extent and improves the efficiency of air treatment. At the same time, compared with the traditional straight air duct, under the condition of the same air duct length, the space volume occupied by the air duct can be reduced, thereby reducing the volume of the shell, which is convenient for users to use. At the same time, under the condition of the same occupied volume, the U-shaped air duct can be equipped with more functional modules, thereby improving the competitiveness of the product. In addition, since the filter module is mainly installed in the return air channel, the space occupied by the filter module is relatively sufficient. Therefore, under the condition of the same wind area, the filter module can be thicker, the overall filter area is larger, and the service life is longer, which greatly extends the replacement cycle of the filter module.

[0012] In an optional embodiment, the air handling cabinet further includes:

[0013] A duct interface is arranged on the return air channel and / or the supply air channel; the duct interface consists of a duct neck and a flange portion, the duct neck is arranged on the return air channel or the supply air channel, the flange portion is an annular structure, and can be detachably sleeved on the duct neck.

[0014] Beneficial effects: The embodiment of the present invention splits the pipe interface into a pipe neck and a flange portion, and the pipe interface can be adjusted according to actual conditions. When the technician needs to install a flanged pipe on the shell, the pipe interface can be directly installed, and the pipe can be docked with the flange portion of the pipe interface to complete the pipe docking. When the technician needs to install a straight-edge pipe on the shell, the technician can directly remove the flange portion on the pipe interface from the pipe neck, so that the pipe interface becomes a straight edge, so that it can be docked with the straight-edge pipe, thereby improving the versatility of the accessories. Compared with the traditional fixed form of the pipe interface, the pipe interface in this embodiment is more flexible and can facilitate the technician to assemble to a certain extent.

[0015] In an optional embodiment, the cross-sectional areas of the return air channel and the supply air channel are the same, and the wind speed of the return air channel is less than 2 m / s.

[0016] Beneficial effects: The embodiment of the present invention sets the cross-sectional area of ​​the return air channel and the supply air channel to be the same, which can ensure that the air flows more evenly in the two channels. This helps to avoid situations where the local wind speed is too high or too low, thereby improving the air treatment effect of the entire system. In addition, the wind speed of the return air channel is less than 2m / s, which can effectively reduce turbulence and pressure loss during air flow. Low wind speed helps to maintain the stability and smoothness of air flow, reduce energy consumption, and improve the energy efficiency of the system. At the same time, lower wind speeds can increase the residence time of air in the filter module, thereby improving filtration efficiency. Dust and particulate matter in the air are more easily captured, reducing pollution to subsequent modules and extending the service life of the equipment. Furthermore, low wind speeds can significantly reduce the noise generated during air flow, improve the quietness of equipment operation, and improve the use environment.

[0017] In an optional embodiment, the filter module is disposed in an upstream area of ​​the return air channel, and an electrical component is disposed in a downstream area of ​​the return air channel.

[0018] Beneficial effect: Since the electrical components need to be connected to internal load lines and engineering wiring, a sealed structure design is required to avoid cold bridges and external condensation. In this embodiment, the electrical components are placed in the return air duct, behind the filter module and before the heat exchange module. This can effectively reduce the sealing design pressure of the electrical components and the leakage caused by production errors, and effectively improve the overall safety of the equipment.

[0019] In an optional embodiment, along the vertical direction, the heat exchange channel is located in the bottom area of ​​the shell, and the return air channel and the supply air channel are located above the heat exchange channel.

[0020] Beneficial effects: This embodiment sets the heat exchange channel at the bottom, which can prevent the condensed water generated by the heat exchange module during the heat exchange process from falling into other equipment under the action of wind flow, thereby ensuring the overall safety of the equipment. At the same time, it is also convenient to collect and discharge the condensed water, reducing the impact of the condensed water on other components. In addition, the heat exchange channel is located in the bottom area of ​​the shell, and gravity can be used to allow natural convection of cold and hot air to improve heat exchange efficiency. Cold air is usually heavier and will naturally sink to the heat exchange channel, while hot air is lighter and will rise. This layout is conducive to natural convection and reduces energy consumption. Furthermore, this vertical layout allows the various channels to be arranged in an orderly manner in a limited space, saving installation space, and is particularly suitable for places with limited space.

[0021] In an optional embodiment, the heat exchange module is placed obliquely in the heat exchange channel.

[0022] Beneficial effects: In this embodiment, tilting the heat exchange module can increase the contact area between the heat exchange module and the wind flow, thereby improving the heat exchange efficiency. More contact area means more heat transfer opportunities, making the heat exchange process more efficient. At the same time, the tilted heat exchange module can play a certain guiding role, guiding the air to flow along a specific path, reducing the dead corners of air flow, allowing air to pass through the heat exchange module more evenly, and improving the heat exchange effect. Furthermore, tilting can reduce the resistance of air passing through the heat exchange module, making the air flow smoother. This helps to reduce the power consumption of the fan and improve the energy efficiency ratio of the system. It can also further reduce air resistance and improve the smoothness of air flow.

[0023] In an optional embodiment, the heat exchange module includes:

[0024] A surface cooler, which has a rectangular structure and is obliquely arranged in the heat exchange channel;

[0025] A humidifier, arranged in the heat exchange channel;

[0026] A water receiving pan is arranged at the bottom of the surface cooler and the humidifier; the water receiving pan is used to receive condensed water from the surface cooler and the humidifier.

[0027] Beneficial effects: In this embodiment, the water receiving pan is arranged at the bottom of the cooler and the humidifier, which can effectively receive the condensed water from the cooler and the humidifier. This not only reduces the accumulation of condensed water on the heat exchange module, prevents the condensed water from affecting the heat exchange effect, but also avoids the contamination and damage of other components by the condensed water. At the same time, the cooler and the humidifier share a water receiving pan, thereby simplifying the structure, saving internal space, and reducing production costs to a certain extent.

[0028] In an optional embodiment, an air supply port is provided at the end of the air supply channel along the wind flow direction, and the silencer module is provided at the air supply port.

[0029] Beneficial effects: This embodiment sets the silencer module at the air outlet, which can effectively reduce the noise generated during the air supply process and reduce the interference to the surrounding environment. The silencer module can reduce the vibration and impact generated during the air supply process, reduce the degree of wear of the equipment, and extend the service life of the equipment. Due to the protective effect of the silencer module, the operation of the equipment is more stable, the failure caused by vibration and impact is reduced, and the maintenance cost is reduced.

[0030] In an optional embodiment, the silencing module is composed of a plurality of silencing units; the plurality of silencing units are arranged along the wind flow direction;

[0031] Each silencer unit is provided with a plurality of silencer plates, the plurality of silencer plates are arranged in the same direction, and a gap is provided between two adjacent silencer plates;

[0032] The silencer plate is provided with a windward angle at a position close to the fan module, and / or the silencer plate is provided with a windward angle at a position far from the fan module.

[0033] Beneficial effect: This embodiment arranges multiple silencer plates in the same direction. When the wind flows through, it is divided into multiple silencer spaces by the silencer plates. In each silencer space, the silencer plates can use their own large number of tiny interconnected pores to silence the sound, so that the sound waves generated by the wind flowing through the silencer plates penetrate deep into the interior along the micropores of the silencer plates, and rub against the internal materials of the silencer plates, converting the sound energy into heat energy, so that the silencer unit has a good noise reduction effect. In addition, this embodiment sets a windward angle on the silencer plates, which can reduce the wind resistance of the silencer plates when the wind flows through the silencer plates, thereby reducing the sound generated by the friction between the wind flow and the silencer plates and reducing energy consumption. At the same time, the silencer plates are set with a wind departure angle. When the wind flows through the tail of the silencer plates, the wind departure angle can separate the wind flow at the tail, and at the same time can enhance the flow characteristics of the wind flow, which can reduce the noise generated when the wind flow at the tail is turbulent to a certain extent, and further improve the silencer ability. Furthermore, this embodiment sets the windward angle and the wind departure angle on the silencer plate, which is equivalent to a fool-proof design of the silencer plate, thereby facilitating maintenance and disassembly and assembly by technical personnel.

[0034] In an optional embodiment, a door body and a door panel cooperating with the door body are provided on the air duct, and a sealing strip is circumferentially provided on the edge of the door panel. When the door panel is buckled with the door body, the sealing strip is tightly fitted with the inner wall edge of the door body.

[0035] Beneficial effects: The coordinated design of the door body and the door panel in this embodiment makes the interior of the wind cabinet easy to inspect and maintain. The door body can be easily opened for cleaning and repair when necessary, reducing maintenance time and costs. In addition, maintenance is more convenient and can be replaced or repaired independently, extending the service life of the equipment. At the same time, in this embodiment, a sealing strip is provided on the circumference of the edge of the door panel. When the door panel is buckled with the door body, the sealing strip fits tightly with the inner wall edge of the door body, which can effectively prevent air leakage. This not only improves the sealing performance of the equipment, but also reduces energy loss and improves energy efficiency. At the same time, good sealing performance can prevent external dust and pollutants from entering the interior of the wind cabinet, keep the interior clean, and extend the service life of the equipment.

[0036] In an optional embodiment, the door panel includes:

[0037] Base plate;

[0038] A frame is arranged on the edge of the bottom plate; the frame is provided with a mounting groove with the notch inward; when the door panel is buckled with the door body, the frame is embedded in the door body; the sealing strip is arranged on the edge of the frame;

[0039] A partition assembly is arranged in the mounting groove and fits with the mounting groove; the bottom of the partition assembly fits with the bottom plate, and a portion of the partition assembly protrudes from the frame to form a mounting portion;

[0040] A top plate covers the partition assembly and is closely connected to the mounting portion; the top plate is a sound-absorbing plate.

[0041] Beneficial effects: In this embodiment, the door panel is composed of a bottom plate, a frame, a partition assembly and a top plate. The multi-layer structure enhances the overall structural stability and makes the door panel more solid and durable. In addition, after the frame is embedded in the door body, the contact area between the door panel and the door body is increased. When the door panel and the door body are buckled, the sealing strip fits tightly with the inner wall edge of the door body, which can effectively prevent air leakage. This not only improves the sealing performance of the equipment, but also reduces energy loss and improves energy efficiency.

[0042] In an optional embodiment, the partition assembly includes:

[0043] A bending plate, adapted to be embedded in the mounting groove, and the bending plate is in abutment with the mounting groove; the bottom end surface of the bending plate is in abutment with the bottom plate, and the bending portion of the bending plate is located on a side away from the mounting groove;

[0044] The vertical plate is riveted to the bent plate so that the vertical plate fits the bent plate; the vertical plate partially protrudes from the frame to form the mounting portion.

[0045] Beneficial effects: This embodiment embeds the bent plate into the mounting groove and fits tightly with the mounting groove, which increases the overall structural strength of the door panel and makes it more stable. In addition, the fitting of the bent plate with the mounting groove, and the fitting of the bottom of the bent plate with the base plate, form a multi-layer seal, further improving the sealing performance of the door panel and effectively preventing air leakage. It also greatly reduces the probability of condensation water appearing on the outside of the panel, ensuring that the whole machine can operate stably even during the rainy season. Good sealing performance can reduce the mixing of cold and hot air, improve the energy efficiency ratio of the system, and reduce energy consumption. At the same time, the bottom end face of the bent plate is fitted with the base plate, which further enhances the rigidity and stability of the structure and reduces the risk of deformation.

[0046] In an optional implementation, the bottom plate, the top plate, and the frame surround and form an installation cavity, and a sound-absorbing material is disposed in the installation cavity.

[0047] Beneficial effects: In this embodiment, sound-absorbing materials are arranged in the installation cavity, which can effectively absorb and reduce the noise generated by air flow and provide a quieter environment. Sound-absorbing materials usually have good sound absorption performance and can reduce the noise propagation when the equipment is running. At the same time, the bottom plate, the top plate and the frame together form a closed installation cavity, which further enhances the sound insulation effect and reduces the interference of external noise. In addition, the installation cavity formed by the bottom plate, the top plate and the frame is a closed space, which can effectively prevent air leakage and improve the sealing performance of the equipment. Good sealing performance can reduce the mixing of cold and hot air, improve the energy efficiency ratio of the system, and reduce energy consumption. Furthermore, the bottom plate, the top plate and the frame together constitute a stable multi-layer structure, which enhances the overall structural strength of the door panel and makes it more sturdy and durable. It can also reduce the impact of the external environment on the door panel, further improving the stability and deformation resistance of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0065] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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 it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0067] The air handling unit mainly relies on the rotation of the fan to drive the indoor (outdoor) air to exchange heat with the internal coil of the unit, and filter the impurities in the air to control the outlet temperature and air volume to maintain the indoor temperature, humidity and air cleanliness. Since the full air cabinet is often installed in the machine room or outdoors, it has the characteristics of large air supply volume, multi-functional adjustment of the whole house, and long-term operation. The existing air handling cabinets on the market generally have problems such as inconvenient connection, high noise, low cooling capacity, poor electrical safety, and short filter life.

[0068] In view of this, the present invention provides an air handling cabinet to solve some or all of the problems existing in the above-mentioned air handling cabinets.

[0069] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

[0070] According to an embodiment of the present invention, on one hand, an air handling cabinet is provided. The air handling cabinet includes a housing 1 , a filter module 14 , a heat exchange module 15 , a fan module 16 and a silencer module 17 .

[0071] Specifically, in this embodiment, an air duct is arranged inside the housing 1, and along the wind flow direction, the air duct includes a return air duct 11, a heat exchange duct 12 and an air supply duct 13 arranged in sequence. Figure 2 As shown, the return air channel 11 and the supply air channel 13 are arranged side by side and in parallel, so that the air channel has a U-shaped structure.

[0072] Furthermore, in the present embodiment, the filter module 14 is arranged in the return air channel 11, and the filter module 14 can be composed of one or more of a primary filter, a high-efficiency filter, and a purification and sterilization unit. These three filter parts can also be set at the same time, and along the wind flow direction, the primary filter, the high-efficiency filter, and the purification and sterilization unit can be arranged in sequence from the outside to the inside. The purification and sterilization unit can be a high-temperature sterilization heating element, an ultraviolet lamp, or an ionization sterilization element. Of course, this embodiment is only an example of the specific composition of the filter module 14, but it is not limited to this. Those skilled in the art can make changes according to actual conditions as long as the same technical effect can be achieved.

[0073] Further, in this embodiment, the heat exchange module 15 is arranged in the heat exchange channel 12, the fan module 16 is arranged in the air supply channel 13, and the silencer module 17 is arranged in the air supply channel 13. And along the wind flow direction, the silencer module 17 is located downstream of the fan module 16.

[0074] In this way, the embodiment of the present invention sets the air duct as a U-shaped structure, so that the air flow path inside the wind cabinet is more reasonable, which reduces the resistance of air flow to a certain extent and improves the efficiency of air treatment. At the same time, compared with the traditional straight air duct, under the condition of the same air duct length, the space volume occupied by the air duct can be reduced, thereby reducing the volume of the shell 1, which is convenient for users to use. At the same time, under the condition of the same occupied volume, the air duct with a U-shaped structure can be equipped with more functional modules, thereby improving the competitiveness of the product. In addition, since the filter module 14 is mainly installed in the return air channel 11, the space occupied by the filter module 14 is relatively sufficient. Therefore, under the condition of the same wind area, the filter module 14 can be thicker, the overall filter area is larger, and the service life is longer, which greatly extends the replacement cycle of the filter module 14.

[0075] Furthermore, in an optional embodiment, the air handling hood also includes a pipe interface 2, which is arranged on the return air channel 11 and the supply air channel 13, usually on the outer side of the return air channel 11 and the supply air channel 13, so that other functional modules can be additionally installed on the hood to further improve the function of the hood.

[0076] In this embodiment, the duct interface 2 is composed of a duct neck 21 and a flange portion 22. The duct neck 21 is arranged on the return air channel 11 or the air supply channel 13. The structural shape of the duct neck 21 is adapted to the return air channel 11 and the air supply channel 13. When the cross-section of the return air channel 11 and the air supply channel 13 is a rectangular structure, the duct neck 21 is also correspondingly set as a rectangular interface. When the cross-section of the return air channel 11 and the air supply channel 13 is a circular structure, the duct neck 21 is also correspondingly set as a circular interface. The flange portion 22 is an annular structure, which of course corresponds to a rectangular ring or a circular ring. And the flange portion 22 is detachably sleeved on the duct neck 21. The flange portion 22 can be a flanged sheet metal, which can be fixed to the duct neck 21 by screws. When a flange-type air duct or a flange-type static pressure box needs to be installed, the flange portion 22 can be installed on the pipe neck 21 . When an inserted straight-edge air duct or an inserted static pressure box needs to be installed, the flange portion 22 can be removed from the pipe neck 21 .

[0077] With such a configuration, the embodiment of the present invention splits the pipe interface 2 into a pipe neck 21 and a flange portion 22, and the pipe interface 2 can be adjusted according to actual conditions. When the technician needs to install a flanged pipe on the housing 1, the pipe interface 2 can be directly installed, and the pipe can be docked with the flange portion 22 of the pipe interface 2, thereby completing the pipe docking. When the technician needs to install a straight-edge pipe on the housing 1, the technician can directly remove the flange portion 22 on the pipe interface 2 from the pipe neck 21, so that the pipe interface 2 becomes a straight edge, so that it can be docked with the straight-edge pipe, thereby improving the versatility of the accessory. Compared with the traditional fixed form of the pipe interface 2, the pipe interface 2 in this embodiment is more flexible, which can facilitate the technician to assemble to a certain extent.

[0078] Further, in an optional embodiment, the cross-sectional areas of the return air channel 11 and the supply air channel 13 are the same, that is, the return air channel 11 and the supply air channel 13 are designed with the same size and are equally divided at 5:5. And the wind speed of the return air channel 11 is less than 2m / s, so that the return air resistance is small and within a predetermined range.

[0079] In this way, the embodiment of the present invention sets the cross-sectional area of ​​the return air channel 11 and the air supply channel 13 to be the same, which can ensure that the air flows more evenly in the two channels. This helps to avoid the situation where the local wind speed is too high or too low, thereby improving the air treatment effect of the entire system. In addition, the wind speed of the return air channel 11 is less than 2m / s, which can effectively reduce turbulence and pressure loss during the air flow. Low wind speed helps to maintain the stability and smoothness of air flow, reduce energy consumption, and improve the energy efficiency of the system. At the same time, a lower wind speed can increase the residence time of air in the filter module 14, thereby improving the filtration efficiency. Dust and particulate matter in the air are more easily captured, reducing pollution to subsequent modules and extending the service life of the equipment. Furthermore, low wind speed can significantly reduce the noise generated during air flow, improve the quietness of equipment operation, and improve the use environment.

[0080] Furthermore, in an optional embodiment, the filter module 14 is provided in the upstream area of ​​the return air channel 11, and an electrical component is provided in the downstream area of ​​the return air channel 11. The electrical component is usually provided with a controller and a power supply for controlling various loads inside the wind cabinet, so a hole needs to be opened and then wired from the outside.

[0081] In this configuration, since the electrical components need to be connected to internal load lines and engineering wiring, a sealing structure design is required to avoid cold bridges and external condensation. In this embodiment, the electrical components are placed in the return air duct 11, behind the filter module 14 and before the heat exchange module 15. This can effectively reduce the sealing design pressure of the electrical components and the leakage caused by production errors, and effectively improve the overall safety of the equipment.

[0082] Further, in an optional embodiment, along the vertical direction, the heat exchange channel 12 is located in the bottom area of ​​the shell 1 , and the return air channel 11 and the supply air channel 13 are located above the heat exchange channel 12 .

[0083] In this way, the heat exchange channel 12 is arranged at the bottom of the present embodiment, which can prevent the condensed water generated by the heat exchange module 15 during the heat exchange process from falling into other equipment under the action of wind flow, thereby ensuring the safety of the entire equipment. At the same time, it is also convenient to collect and discharge the condensed water, reducing the impact of the condensed water on other components. In addition, the heat exchange channel 12 is located in the bottom area of ​​the shell 1, and gravity can be used to allow natural convection of cold and hot air to improve heat exchange efficiency. Cold air is usually heavier and will naturally sink to the heat exchange channel 12, while hot air is lighter and will rise. This layout is conducive to natural convection and reduces energy consumption. Furthermore, this vertical layout allows the various channels to be arranged in an orderly manner in a limited space, saving installation space, and is particularly suitable for places with limited space.

[0084] Furthermore, in an optional embodiment, the heat exchange module 15 is placed obliquely in the heat exchange channel 12. The heat exchange module 15 is generally a rectangular structure. As for the oblique direction, for example, the plane where the heat exchange module 15 is located can be arranged in the vertical direction, one side of the heat exchange module 15 is the return air side, and the other side of the heat exchange module 15 is the supply air side. When the two longitudinal sides of the heat exchange module 15 are at the diagonal position of the heat exchange channel 12, the contact area between the airflow and the heat exchange module 15 is the largest, which can improve the heat exchange efficiency and heat exchange capacity.

[0085] Of course, the plane where the heat exchange module 15 is located can also be further arranged along an inclined direction, so that there is an angle between the plane where the heat exchange module 15 is located and the vertical direction. In this case, it is necessary to set reserved air vents between the air supply channel 13 and the heat exchange channel 12 and between the return air channel 11 and the heat exchange channel 12 so that the air flow can enter normally.

[0086] When the heat exchange module 15 is tilted, Figure 4 As shown, the air vents between the supply air side and the return air channel 11 in the heat exchange channel 12, and the air vents between the return air side and the supply air channel 13 need to be sealed accordingly to avoid air leakage.

[0087] With such arrangement, in this embodiment, placing the heat exchange module 15 at an angle can increase the contact area between the heat exchange module 15 and the wind flow, thereby improving the heat exchange efficiency. More contact area means more heat transfer opportunities, making the heat exchange process more efficient. At the same time, the inclined heat exchange module 15 can play a certain guiding role, guiding the air to flow along a specific path, reducing the dead corners of air flow, allowing the air to pass through the heat exchange module 15 more evenly, and improving the heat exchange effect. Furthermore, the inclined placement can reduce the resistance of air when passing through the heat exchange module 15, making the air flow smoother. This helps to reduce the power consumption of the fan and improve the energy efficiency ratio of the system. It can also further reduce air resistance and improve the smoothness of air flow.

[0088] Furthermore, in an optional implementation, the heat exchange module 15 includes: a surface cooler 151 , a humidifier 152 and a water receiving tray 153 .

[0089] Specifically, in this embodiment, the cooler 151 is a rectangular structure and is obliquely arranged in the heat exchange channel 12. The cooler 151 is placed in the heat exchange channel 12, at the bottom of the wind cabinet, which effectively reduces the problem of water splashing from the cooler 151 caused by excessive local wind speed, and effectively improves the safety of the fan module 16 and other functional modules. The humidifier 152 is arranged in the heat exchange channel 12, and the water receiving tray 153 is arranged at the bottom of the cooler 151 and the humidifier 152. The water receiving tray 153 is used to receive condensed water from the cooler 151 and the humidifier 152.

[0090] In this way, the water receiving pan 153 is arranged at the bottom of the cooler 151 and the humidifier 152 in this embodiment, which can effectively receive the condensed water from the cooler 151 and the humidifier 152. This not only reduces the accumulation of condensed water on the heat exchange module 15, prevents the condensed water from affecting the heat exchange effect, but also avoids the contamination and damage of other components by the condensed water. At the same time, the cooler 151 and the humidifier 152 share a water receiving pan 153, thereby simplifying the structure, saving internal space, and reducing production costs to a certain extent.

[0091] Further, in an optional embodiment, an air supply port is provided at the end of the air supply channel 13 along the wind flow direction, and the silencer module 17 is provided at the air supply port.

[0092] In this way, the present embodiment sets the silencer module 17 at the air outlet, which can effectively reduce the noise generated during the air supply process and reduce the interference to the surrounding environment. The silencer module 17 can reduce the vibration and impact generated during the air supply process, reduce the degree of wear of the equipment, and extend the service life of the equipment. Due to the protective effect of the silencer module 17, the operation of the equipment is more stable, the failure caused by vibration and impact is reduced, and the maintenance cost is reduced.

[0093] Furthermore, in an optional embodiment, the silencing module 17 is composed of a plurality of silencing units, and the plurality of silencing units are arranged along the wind flow direction. That is, when the wind enters, the wind flow will pass through the plurality of silencing units in sequence for silencing.

[0094] Furthermore, a plurality of silencer plates are provided in each silencer unit, and the plurality of silencer plates are arranged in the same direction, and a gap is provided between two adjacent silencer plates. Specifically, the silencer plate can be fixedly provided in the silencer unit, or can be movably provided in the silencer unit. As for the installation direction of the silencer plate, when the silencer plate is a flat plate, the plate surface of the silencer plate can be provided parallel to the air inlet direction, or can be provided at an angle. When the silencer plate is a corrugated plate or other types of plate surfaces with a certain bending angle, the overall extension direction of the silencer plate can be provided parallel to the air inlet direction. In this way, the contact length between the silencer plate and the wind flow can be increased as much as possible, thereby increasing the silencer effect of the silencer plate.

[0095] Of course, as for the installation direction of the silencer plate, those skilled in the art can change it according to the actual situation. This embodiment is only an example for illustration, but it is not limited to this. It is sufficient to achieve the same technical effect.

[0096] Further, the muffler plate is provided with a windward angle at a position close to the fan module 16, and the muffler plate is provided with a windward angle at a position away from the fan module 16. That is, the side of the muffler plate close to the air inlet side is provided with a windward angle, and the side of the muffler plate close to the air outlet side is provided with a windward angle. Of course, only the windward angle or the windward angle may be provided, and this embodiment is merely an example.

[0097] In this way, the embodiment arranges multiple silencers in the same direction. When the wind flows through, it is divided into multiple silencer spaces by the silencer. In each silencer space, the silencer can use its own large number of tiny connected pores to silence the sound, so that the sound waves generated by the wind flowing through the silencer go deep into the interior along the micropores of the silencer, and rub against the internal material of the silencer to convert the sound energy into heat energy, so that the silencer unit has a good noise reduction effect. In addition, the embodiment sets a windward angle on the silencer, which can reduce the wind resistance of the silencer when the wind flows through the silencer, thereby reducing the sound generated by the friction between the wind and the silencer, and reducing energy loss. At the same time, the silencer is set with a wind departure angle. When the wind flows through the tail of the silencer, the wind departure angle can separate the wind flow at the tail, and at the same time can strengthen the flow characteristics of the wind flow, which can reduce the noise generated when the wind flow at the tail is turbulent to a certain extent, and further improve the silencer ability. Furthermore, this embodiment sets the windward angle and the wind departure angle on the silencer plate, which is equivalent to a fool-proof design of the silencer plate, thereby facilitating maintenance and disassembly and assembly by technical personnel.

[0098] Furthermore, in an optional embodiment, a door body 18 and a door panel 19 cooperating with the door body 18 are provided on the air duct, and a sealing strip is circumferentially provided on the edge of the door panel 19. When the door panel 19 is buckled with the door body 18, the sealing strip fits tightly against the inner wall edge of the door body 18.

[0099] In the present embodiment, the sealing strip is fixed by a dispensing process. Compared with the traditional air conditioner cabinet door panel 19, the door panel 19 of the present embodiment is more durable and has better sealing performance, which effectively reduces air leakage.

[0100] The size of the sealing strips can be customized according to actual conditions, and these sealing strips are fixed along the folded edge of the door panel 19 by using a dispensing technique. In the final assembly process, the door panel 19 is closely connected with the frame of the door body 18, so that the sealing strips are precisely fitted with the frame of the door body 18. Thanks to the elasticity and compressibility of the sealing strips, the wind cabinet of this embodiment exhibits excellent sealing performance, while enhancing its durability and operating efficiency.

[0101] With such arrangement, the coordinated design of the door body 18 and the door panel 19 in this embodiment makes the interior of the wind cabinet easy to inspect and maintain. The door body 18 can be easily opened for cleaning and repair when necessary, reducing maintenance time and cost. In addition, maintenance is more convenient, and it can be replaced or repaired independently, extending the service life of the equipment. At the same time, a sealing strip is provided on the circumference of the edge of the door panel 19 in this embodiment. When the door panel 19 is buckled with the door body 18, the sealing strip fits tightly with the inner wall edge of the door body 18, which can effectively prevent air leakage. This not only improves the sealing performance of the equipment, but also reduces energy loss and improves energy efficiency. At the same time, good sealing performance can prevent external dust and pollutants from entering the interior of the wind cabinet, keep the interior clean, and extend the service life of the equipment.

[0102] Furthermore, in an optional embodiment, the door panel 19 includes a bottom panel 191 , a frame 192 , a partition assembly 193 and a top panel 194 .

[0103] Specifically, in this embodiment, the frame 192 is arranged on the edge of the bottom plate 191, and the frame 192 is provided with an inwardly notched mounting groove, and when the door panel 19 is buckled with the door body 18, the frame 192 is embedded in the door body 18. The sealing strip is arranged on the edge of the frame 192. Furthermore, the frame 192 can be formed by directly flanging the bottom plate 191 sheet metal inward, so that the overall structure of the door panel 19 is more stable and more sealed.

[0104] Furthermore, in this embodiment, the partition assembly 193 is disposed in the mounting groove and fits with the mounting groove, the bottom of the partition assembly 193 fits with the bottom plate 191, and the partition assembly 193 partially protrudes from the frame 192 to form a mounting portion. The partition assembly 193 is used to seal the inside of the frame 192, thereby greatly reducing the probability of condensed water on the sheet metal outside the air outlet cavity, ensuring that the whole machine can operate stably even in the rainy season.

[0105] Furthermore, in the present embodiment, the top plate 194 covers the partition assembly 193 and is connected to the mounting portion, and the top plate 194 is a muffler. In the present embodiment, the muffler is a microporous muffler, which is made of a 1.0 mm thick sheet metal material and is precisely perforated according to a standard of 3 mm aperture. The layout of the holes is 6 mm in horizontal hole spacing and 7 mm in vertical hole spacing. A layer of 2.0 mm thick polyester fiber cotton can be pasted on the inner bottom of the muffler to enhance its muffler effect. Subsequently, the muffler is fixed to the partition assembly 193 to ensure the stability of the structure and the muffler performance.

[0106] In this way, in this embodiment, the door panel 19 is composed of a bottom plate 191, a frame 192, a partition assembly 193 and a top plate 194. The multi-layer structure enhances the overall structural stability and makes the door panel 19 more durable. In addition, after the frame 192 is embedded in the door body 18, the contact area between the door panel 19 and the door body 18 is increased. When the door panel 19 and the door body 18 are buckled, the sealing strip is tightly fitted with the inner wall edge of the door body 18, which can effectively prevent air leakage. This not only improves the sealing performance of the equipment, but also reduces energy loss and improves energy efficiency.

[0107] Furthermore, in an optional embodiment, the partition assembly 193 includes a bent plate 1931 and a vertical plate 1932 .

[0108] Specifically, in this embodiment, the bending plate 1931 is suitable for being embedded in the installation slot, and the bending plate 1931 is in close contact with the installation slot. The bottom end surface of the bending plate 1931 is in close contact with the bottom plate 191, and the bending portion of the bending plate 1931 is located on a side away from the installation slot.

[0109] Furthermore, in this embodiment, the vertical plate 1932 is riveted to the bent plate 1931 so that the vertical plate 1932 fits the bent plate 1931 , and a portion of the vertical plate 1932 protrudes from the frame 192 to form the mounting portion.

[0110] During the implementation process, the bent plate 1931 and the vertical plate 1932 are first fixedly connected by M6 rivet screws. Then, the formed partition assembly 193 is further firmly combined with the bottom plate 191 by M6 rivet screws. Subsequently, the top plate 194 is covered on the partition assembly 193 and fixed by side rivets. Finally, the prefabricated sealing strip is fixed in the corresponding position through a precise gluing process to ensure the sealing and stability of the overall structure.

[0111] With such arrangement, the present embodiment embeds the bending plate 1931 into the mounting groove and fits tightly with the mounting groove, thereby increasing the overall structural strength of the door panel 19 and making it more stable. In addition, the fitting of the bending plate 1931 with the mounting groove and the fitting of the bottom of the bending plate 1931 with the bottom plate 191 form a multi-layer seal, further improving the sealing performance of the door panel 19 and effectively preventing air leakage. It also greatly reduces the probability of condensation water appearing on the outside of the panel, ensuring that the whole machine can operate stably even during the rainy season. Good sealing performance can reduce the mixing of cold and hot air, improve the energy efficiency ratio of the system, and reduce energy consumption. At the same time, the bottom end face of the bending plate 1931 is fitted with the bottom plate 191, which further enhances the rigidity and stability of the structure and reduces the risk of deformation.

[0112] Furthermore, in an optional implementation, the bottom plate 191, the top plate 194, and the frame 192 surround and form an installation cavity, and a sound-absorbing material 195 is disposed in the installation cavity.

[0113] In this way, the present embodiment is provided with a sound-absorbing material 195 in the installation cavity, which can effectively absorb and reduce the noise generated by the air flow, and provide a quieter environment. The sound-absorbing material 195 usually has good sound absorption performance, which can reduce the noise propagation when the equipment is running. At the same time, the bottom plate 191, the top plate 194 and the frame 192 together form a closed installation cavity, which further enhances the sound insulation effect and reduces the interference of external noise. In addition, the installation cavity formed by the bottom plate 191, the top plate 194 and the frame 192 is a closed space, which can effectively prevent air leakage and improve the sealing performance of the equipment. Good sealing performance can reduce the mixing of cold and hot air, improve the energy efficiency ratio of the system, and reduce energy consumption. Furthermore, the bottom plate 191, the top plate 194 and the frame 192 together constitute a stable multi-layer structure, which enhances the overall structural strength of the door panel 19 and makes it more sturdy and durable. It can also reduce the impact of the external environment on the door panel 19, and further improve the stability and anti-deformation ability of the structure.

[0114] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
