Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a dehumidification device and electrical equipment. Background Technology

[0002] In the installation and use of modern electrical equipment, electrical boxes serve as important protective and management devices, widely used in various situations. However, in some of these situations, such as high-humidity environments or environments with large day-night temperature differences, condensation can easily form inside the electrical box, affecting the electrical safety of the equipment. Therefore, dehumidifiers are usually installed in electrical equipment to dehumidify the air inside the box. However, continuous operation of dehumidifiers can shorten their lifespan. Utility Model Content

[0003] This application provides a dehumidification device to solve the technical problem that continuous operation of a dehumidifier will affect its service life; another objective of this application is to provide an electrical device.

[0004] To achieve the above objectives, according to a first aspect of this application, a dehumidification device is provided for use in electrical equipment, the dehumidification device comprising:

[0005] A sensor, adapted to be installed inside the enclosure of the electrical equipment, and used to monitor the temperature and humidity inside the enclosure;

[0006] A condensation assembly, adapted to be disposed within the housing and electrically connected to the sensor, the condensation assembly being used to condense water vapor and having a water outlet;

[0007] The drainage assembly connects the water outlet and the external space of the housing.

[0008] Optionally, the condensation assembly includes a condensation section and a water collection section, the water collection section being configured to contain liquid medium falling from the condensation section, and the water outlet being disposed in the water collection section.

[0009] Optionally, the condenser is either a semiconductor refrigerator or a heat exchanger.

[0010] Optionally, the drainage component is positioned in the direction in which the liquid medium falls naturally from the outlet.

[0011] Optionally, the drainage assembly is disposed inside the housing, or the drainage assembly is disposed outside the housing.

[0012] Optionally, the drainage assembly includes a solenoid valve having an input port and an output port, the input port communicating with the outlet and the output port communicating with the external space of the housing.

[0013] Optionally, the dehumidification device further includes a waterproof and breathable component, which is adapted to be installed in the housing so that the internal space of the housing is connected to the external space.

[0014] Optionally, the waterproof and breathable component is one of a waterproof and breathable valve, an expanded polytetrafluoroethylene membrane, or a polyurethane membrane.

[0015] Optionally, the number of sensors is set to multiple and they are used to be located at different positions inside the housing.

[0016] According to a second aspect of this application, an electrical device is provided, comprising:

[0017] Box;

[0018] The aforementioned dehumidification device is installed in the housing.

[0019] In the dehumidification device of this application embodiment, sensors monitor the temperature and humidity inside the chamber. When the temperature and humidity reach a certain value, the condensation component operates, condensing water vapor in the air into liquid water, which is then discharged to the outside of the chamber through the drainage component. When the temperature and humidity inside the chamber do not reach the set value, the condensation component does not operate. This intermittent operation of the condensation component reduces wear and tear caused by continuous operation, thus helping to extend its service life. The condensate is directly discharged to the outside of the chamber through the drainage component, avoiding contact with internal components and protecting the electrical safety of the equipment.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0029] In the description of this application, it should be understood that the terms "height," "thickness," "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, and "at least one" can mean one, two, or more, unless otherwise expressly specified.

[0030] Please see Figure 1 and Figure 2 This application provides a dehumidification device for use in electrical equipment. The dehumidification device includes a sensor 1, a condensation component 2, and a drainage component 3.

[0031] The sensor 1 is adapted to be installed inside the enclosure 5 of the electrical equipment and is used to monitor the temperature and humidity inside the enclosure 5. It is understood that the enclosure 5 has a receiving cavity for accommodating electrical components, and the space inside the enclosure 5 or the interior space of the enclosure 5 is the receiving cavity.

[0032] The condenser assembly 2 is adapted to be installed inside the housing 5 and electrically connected to the sensor 1. The condenser assembly 2 is used to condense water vapor and has a water outlet 20 so that the condensed liquid medium can be discharged from the water outlet 20 after dripping.

[0033] The drainage component 3 is connected to the outlet 20 and the external space of the tank 5 respectively, so as to discharge the liquid medium to the outside of the tank 5.

[0034] The electrical connection in this embodiment can be either wired or wireless. For example, to control the condenser assembly 2, the dehumidifier also includes a main control unit, a power drive module, and a power supply module. Sensor 1 is connected to the main control unit via a data cable for transmitting temperature and humidity monitoring data; the main control unit is connected to the power drive module via a control signal line for transmitting start / stop control signals for the condenser assembly 2; the power drive module is connected to the condenser assembly 2 via a power cable for providing operating power; and the power supply module is connected to the main control unit, sensor 1, and power drive module via power cables to provide operating power. If a wireless connection is used, the above components can be replaced with a wireless module, utilizing Bluetooth or Wi-Fi for communication.

[0035] Sensor 1 monitors the temperature and humidity inside the enclosure 5, causing the condenser assembly 2 to activate only when the temperature and humidity reach a set threshold. This condenser condenses water vapor in the air into liquid water, which is then discharged outside the enclosure 5 via the drain assembly 3. Once the temperature and humidity inside the enclosure 5 return to normal, the condenser assembly 2 stops operating. This intermittent operation of the condenser assembly 2 reduces mechanical wear and electrical aging caused by prolonged continuous operation, thus extending its service life. Dehumidification of the air inside the enclosure 5 also reduces the risk of short circuits, corrosion, or decreased insulation performance in electrical equipment due to excessive humidity, improving equipment reliability.

[0036] Please see Figure 1 and Figure 2 In some embodiments, the condensing assembly 2 includes a condensing section 21 and a water collecting section 22. The condensing section 21 has a cooling function, causing water vapor to condense and adhere to its surface, forming a liquid medium. The water collecting section 22 is configured to collect the liquid medium falling from the condensing section 21, and an outlet 20 is disposed in the water collecting section 22. The water collecting section 22 can be an independent water receiving container such as a water receiving tray or funnel, which is disposed below the outlet 20 to collect condensate. The water collecting section 22 can also be a shell structure of the condensing assembly 2, that is, the condensing section 21 is disposed inside the water collecting section 22, and the condensate falling under the action of gravity collects at the bottom of the water collecting section 22 and is discharged from the outlet 20. The water collecting section 22 and the condensing section 21 can be a separate structure or an integrated structure. In the case of an integrated structure, the water collecting section 22 can be a tank structure of the condensing section 21, and the outlet 20 is connected to the tank structure.

[0037] The water collection section 22 is located below the condensation section 21. It uses gravity to guide the water flow, so that the condensate flows unidirectionally to the outside of the box 5 to prevent short circuits in electrical equipment.

[0038] Please see Figure 1 and Figure 2In some embodiments, the condenser 21 is either a semiconductor refrigerator or a heat exchanger. When the condenser 21 is a semiconductor refrigerator, the semiconductor refrigerator includes a cold end and a hot end, with the cold end disposed opposite to the water collection section 22.

[0039] In the case of a condenser section 21 with a heat exchanger, the heat exchanger can be a plate heat exchanger, which can be cooled by air cooling, liquid cooling or phase change working fluid so that water vapor condenses on the surface of the heat exchanger.

[0040] The condenser section 21 can be selected according to factors such as required space, cooling capacity, and installation method to meet the usage needs of different operating conditions, offering high flexibility.

[0041] Please see Figure 1 and Figure 2 In some embodiments, the drainage component 3 is positioned in the direction in which the liquid medium naturally falls from the outlet 20, that is, when the electrical equipment is normally placed, the drainage component 3 is located below the outlet 20. The liquid medium falls naturally to the drainage component 3 under the action of gravity, which helps to reduce energy consumption and simplify the structure. In this embodiment, the drainage component 3 is located directly below the outlet 20, which can shorten the falling distance and accelerate the discharge of condensate.

[0042] Please see Figure 3 In some other embodiments, the drainage component 3 can also be located at other positions of the condensation component 2. When the drainage component 3 is lower than the outlet 20, the liquid medium can flow to the drainage component 3 by gravity. When the drainage component 3 is higher than the outlet 20, an additional driving force can be added by a pump to make the liquid medium flow to the drainage component 3.

[0043] Please see Figure 1 In some embodiments, the drainage component 3 is disposed inside the housing 5. The housing 5 serves to protect the drainage component 3, and in this embodiment, the drainage component 3 is located below the outlet 20, which can further shorten the flow time of the liquid medium.

[0044] Please see Figure 5 In some embodiments, the drainage component 3 is disposed outside the housing 5, which can make full use of the external space of the housing 5 and flexibly arrange the relative positions of the drainage component 3 to adapt to different installation requirements.

[0045] Please see Figure 1 and Figure 4In some embodiments, the drainage assembly 3 includes a solenoid valve 31, which has an input port 311 and an output port 312. The input port 311 is located above the output port 312 and communicates with the outlet 20. The output port 312 communicates with the external space of the housing 5. In this embodiment, the housing 5 is provided with a drain port 51 communicating with its external space, and the drain port 51 is located below the outlet 20. The solenoid valve 31 is located inside the housing 5 and between the outlet 20 and the drain port 51. The output port 312 is connected to the drain port 51.

[0046] The solenoid valve 31 has a closed state and an open state. In the closed state, the valve core of the solenoid valve 31 blocks the inlet valve port 311 and the outlet valve port 312, which prevents condensate from being discharged and restricts the backflow of external air from the drain port 51 into the housing 5, thereby maintaining the existing electrical environment inside the housing 5. In the open state, the valve core of the solenoid valve 31 is misaligned with the inlet valve port 311 and the outlet valve port 312, allowing condensate to be discharged to the outside of the housing 5 from the outlet 20, the inlet valve port 311, and the outlet valve port 312.

[0047] The solenoid valve 31 can be electrically connected to the main control unit to control the opening and closing of the solenoid valve 31, so that the solenoid valve 31 can automatically drain water under different set conditions, such as immediate drainage, periodic drainage, or drainage according to water volume.

[0048] In some other embodiments, the drainage component 3 may also include pipes and electric valves, with the pipes connecting the outlet 20 and the external space of the housing 5 respectively, and the electric valves connected in series with the pipes to control whether or not condensate is discharged from the pipes.

[0049] Please see Figure 1 In some embodiments, the dehumidification device further includes a waterproof and breathable component 4, which is adapted to be installed in the housing 5 to connect the internal space and the external space of the housing 5. Specifically, the housing 5 is provided with vent holes 52, and the waterproof and breathable component 4 covers the vent holes 52, allowing air circulation between the inside and outside of the housing 5 through the vent holes 52, so as to balance the air pressure inside the housing 5 and prevent the flow of liquid media, further increasing the electrical safety of the equipment.

[0050] Please see Figure 1 In some embodiments, the waterproof and breathable component 4 is one of a waterproof and breathable valve, an expanded polytetrafluoroethylene membrane, or a polyurethane membrane. The waterproof and breathable component 4 can be selected according to different working conditions, offering high flexibility.

[0051] Please see Figure 1In some embodiments, multiple sensors 1 are provided and are installed at different locations inside the housing 5. That is, each sensor 1 can be distributed on different inner wall surfaces of the housing 5, or at different locations on the same inner wall surface of the housing 5. The temperature and humidity data detected by the sensors 1 at different locations are used to determine whether the condenser assembly 2 should be turned on for dehumidification, which helps to improve the detection accuracy, ensures that the condenser assembly 2 reaches the preset conditions for activation, and improves resource utilization.

[0052] Accordingly, the electrical equipment provided in this embodiment includes a housing 5 and the dehumidification device described in the above embodiment. The dehumidification device is installed in the housing 5 and is used to dehumidify the internal space of the housing 5. This electrical equipment can be an inverter, energy storage cabinet, control cabinet, substation, etc., and has all the technical features and beneficial effects of the dehumidification device described above, which will not be repeated here.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
