Moreover, the sealing box can provide a more complete electromagnetic shielding effect, reducing the interference of external electromagnetic signals on the controller, ensuring the stable operation of the control system, especially suitable for environments with strong electromagnetic interference. Further, when the sealing box is made of a solid material, the entire electric control assembly can have good anti-shock and impact performance, effectively protecting the internal components from physical damage during transportation and use. Thus, through multiple protection measures, the electric control assembly can be ensured to operate stably for a long time in various environments, reducing the failure rate and maintenance cost.

[0037] In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as there is no conflict.

[0038] The multifunctional air cabinet is mainly driven by the fan rotation to drive indoor and outdoor air to exchange heat with the internal coil of the unit, filter impurities in the air, control the temperature and air volume of the outlet air, and maintain indoor temperature, humidity and air cleanliness.The air cabinet is usually installed in the outdoor environment, and when extreme high temperature and high humidity or low dew point external climate is encountered, the air flow is treated at low temperature through the air duct, so that condensate water is easily generated in the air duct.The electric control box of the air cabinet is usually arranged in the air duct, so that the condensate water causes certain safety risk to the electric control box when external lead and maintenance of the electric control box are carried out.

[0039] Therefore, the utility model provides an air cabinet for preventing condensate water to solve the problem that condensate water causes certain safety risk to the electric control box.

[0040] The embodiments of the utility model are described below in combination with Figs. 1 to 3 , the description of the utility model.

[0041] According to the embodiments of the utility model, on the one hand, an air cabinet for preventing condensate water is provided, which comprises a shell 1 and an electric control assembly 2.

[0042] Specifically, in the embodiment, the shell 1 is provided with an air inlet channel, a heat exchange channel and an air outlet channel which are sequentially communicated.The air flow sequentially passes through the air inlet channel, the heat exchange channel and the air outlet channel.And along the vertical direction, the heat exchange channel is at the bottom of the shell 1, so that the air inlet channel and the air outlet channel are higher than the heat exchange channel.The electric control assembly 2 is arranged in the air inlet channel.The electric control assembly 2 is used for controlling the working state of each load in the air cabinet to regulate and control the overall operation state of the air cabinet.

[0043] With this configuration, the heat exchange channel in this embodiment is located at the bottom of the housing 1, which fully utilizes gravity to facilitate the drainage of condensate or condensate deposits, preventing condensate from affecting the heat exchange effect. Furthermore, condensate generated when airflow passes through the heat exchange channel will fall directly into the drip tray under the influence of gravity and airflow, thus not affecting the electrical control components 2. Additionally, the airflow temperature in the air inlet channel is closer to the indoor ambient temperature and humidity, and its sensible heat temperature is higher, making it less likely for cold bridges and convective cooling to be conducted into the electrical control box, greatly reducing the risk of condensation caused by non-design errors between the electrical control box and the external environment.

[0044] Furthermore, in one optional embodiment, the air intake duct is either a return air duct or a mixed air duct. The return air duct is a duct that directly connects to the indoor environment, while the mixed air duct is where return air is mixed with fresh air from the outside to form a mixed air duct before being output. This allows for the control of the fresh air intake through a reasonable strategy and the rational utilization of return air, achieving a balance between good indoor oxygen levels and system energy conservation.

[0045] Furthermore, in an optional embodiment, the electronic control component 2 includes a base box 21, a controller 22, and a cover 23.

[0046] Specifically, in this embodiment, the bottom box 21 has an internal receiving cavity, and the controller 22 is disposed in the receiving cavity. The lid 23 is fastened to the bottom box 21, and the lid 23 and the bottom box 21 are sealed together. For the sealing method, a sealing element can be provided at the fastening point between the lid 23 and the bottom box 21, or sealant can be directly applied.

[0047] Furthermore, the bottom box 21 and the cover 23 can be either fixedly connected or detachably connected. For a fixed connection, welding, bonding, or other methods can be used. For a detachable connection, screws and screw holes, clips and slots, or magnetic attraction can be used for fixation.

[0048] The detachable connection is exemplified as follows. For example, a fixing plate can be additionally provided on both sides of the box cover 23, and the number of the fixing plates can be changed by those skilled in the art according to actual conditions, such as 1, 2, 3, 4, etc. A screw hole is then formed on the fixing plate, and another screw hole is formed on the bottom box 21 corresponding to the screw hole. Then, the screw is sequentially inserted through the screw hole on the fixing plate and the screw hole on the bottom box 21, so as to connect the box cover 23 and the bottom box 21. Further, when the buckle and the slot are used for fixing, a buckle can be additionally provided on the box cover 23, and the number of the buckle can be changed by those skilled in the art according to actual conditions, such as 1, 2, 3, 4, etc. A slot capable of cooperating with the buckle is then formed on the bottom box 21 corresponding to the buckle. Then, the buckle on the box cover 23 is directly inserted into the slot on the bottom box 21, so as to connect the box cover 23 and the bottom box 21. When the magnetic attraction is used for fixing, a magnetic sheet can be additionally provided on the box cover 23, and the number of the magnetic sheet can be changed by those skilled in the art according to actual conditions, such as 1, 2, 3, 4, etc. A magnetic sheet capable of attracting the magnetic sheet is then formed on the bottom box 21 corresponding to the magnetic sheet. Then, the magnetic sheet on the box cover 23 is directly inserted into the magnetic sheet on the bottom box 21, so as to magnetically connect the box cover 23 and the bottom box 21.

[0049] Of course, the embodiment only exemplifies the fixed connection and the detachable connection, but does not limit the same. Those skilled in the art can change the same according to actual conditions, as long as the same technical effects can be achieved.

[0050] In this way, the accommodating cavity provided in the bottom box 21 provides physical protection for the controller 22, so as to prevent dust, moisture, vibration and other factors in the external environment from damaging the controller 22. Moreover, the sealed connection of the box cover 23 and the bottom box 21 can effectively prevent moisture and dust from entering, further enhances the waterproof and dustproof performance, and ensures that the controller 22 can normally work in a harsh environment. At the same time, the sealed box body can play a certain electromagnetic shielding effect, reduces the influence of external electromagnetic interference on the controller 22, and ensures the stable operation of the control system. Further, the combined design of the bottom box 21 and the box cover 23 makes the installation and dismounting of the controller 22 more convenient, and the maintenance personnel can easily open the box cover 23 to check, debug or replace the controller 22, without the need to dismount the entire air cabinet.

[0051] Further, in an alternative embodiment, the electric control assembly 2 further comprises a sealed box 24, and the sealed box 24 is provided with a sealed cavity, in which the bottom box 21, the controller 22 and the box cover 23 are placed.

[0052] In this embodiment, the sealing box 24 and the bottom box 21 together form a double-sealing structure, further improving the waterproof and dustproof capabilities. Even in a harsh environment with high humidity and high dust, the internal controller 22 can be effectively protected from damage. The design of the sealing box 24 can make the entire electric control assembly 2 achieve a higher protection level, suitable for a wider range of use scenarios. Moreover, the sealing box 24 can provide more complete electromagnetic shielding effect, reducing the interference of external electromagnetic signals on the controller 22, ensuring the stable operation of the control system, especially suitable for environments with strong electromagnetic interference. Further, when the sealing box 24 is made of a solid material, the entire electric control assembly 2 can have good anti-shock and impact performance, effectively protecting the internal components from physical damage during transportation and use. Thus, through multiple protection measures, the electric control assembly 2 can be ensured to operate stably for a long time in various environments, reducing the failure rate and maintenance cost.

[0053] Of course, when the sealing box 24 is made of a heat-insulating material, the sealing box 24 can also have a certain heat-insulating effect while playing a sealing role.

[0054] Further, in an alternative embodiment, the sealing box 24 is made of a metal sheet by sheet metal processing.

[0055] Further, in an alternative embodiment, a sealing strip 4 is arranged at the sheet metal gap of the sealing box 24. The sealing strip 4 is arranged along the extension direction of the gap to completely cover the gap as much as possible.

[0056] In this embodiment, since the sealing box 24 is made of sheet metal, it is inevitable that gaps will be generated on the sealing box 24 or between the sealing box 24 and the bottom box 21 and the box cover 23. Therefore, when the air cabinet is running, the air flow may enter the internal electric control assembly 2 through the gaps. Therefore, the sealing strip 4 can further improve the sealing box 24, improving the overall protection strength of the electric control assembly 2.

[0057] Further, in an alternative embodiment, the electric control assembly 2 further comprises a heat-insulating layer 25 wrapped around the outer surface of the sealing box 24.

[0058] In this embodiment, the heat preservation layer 25 can effectively prevent the influence of external temperature on the inside of the sealed box 24, and completely isolate the cold bridge transmission phenomenon of the electric control assembly 2, which is particularly important for the equipment working in an extreme temperature environment. Further, the heat preservation layer 25 provides a relatively stable temperature environment for the controller 22, reduces the influence of temperature fluctuation on the performance of the control system, and improves the reliability and stability of the system. By maintaining a suitable working temperature, the heat preservation layer 25 can prolong the service life of the controller 22 and related components, reduce the failure rate and maintenance requirements. Of course, when the sealed box 24 is made of a heat preservation material, the heat preservation layer 25 and the sealed box 24 can have a double heat preservation effect, and completely isolate the cold bridge transmission phenomenon.

[0059] Further, in an alternative embodiment, the heat preservation layer 25 is composed of heat preservation cotton. Of course, it can also be composed of aerogel materials or foamed polyethylene materials. Of course, this embodiment is only illustrative, but it is not limited thereto, and those skilled in the art can make changes according to actual conditions, as long as the same technical effects can be achieved.

[0060] Further, in an alternative embodiment, the heat preservation cotton is a polyurethane high-density sponge.

[0061] Further, in an alternative embodiment, the shell 1 and the electric control assembly 2 are provided with through holes for loading wires. The through holes are provided with sealing sleeves 3, which are suitable for the wires to pass through and are in interference fit with the wires.

[0062] In this embodiment, the interference fit between the sealing sleeve 3 and the wire ensures the tight sealing of the through hole, effectively preventing external moisture, dust and other impurities from entering the inside of the shell 1 or the electric control assembly 2 through the through hole. This greatly improves the protection level of the equipment, which is suitable for outdoor or high-humidity and high-dust environments. Moreover, the interference fit of the sealing sleeve 3 can prevent the wire from loosening or falling off at the through hole, reduce the short circuit or poor contact problem caused by the displacement of the wire, and improve the reliability of the electrical connection. At the same time, the sealing sleeve 3 is usually made of insulating material, which further enhances the insulation performance of the wire, prevents electric shock accidents, and ensures the safety of the operator.

[0063] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
