[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 outdoor settings, the protective performance requirements for electrical enclosures used in photovoltaic and energy storage systems are becoming increasingly stringent. However, condensation easily forms inside these sealed enclosures, and prolonged condensation can cause irreversible damage to the equipment, significantly reducing its reliability and lifespan. To address this, dehumidifiers are typically installed inside the enclosures to condense moisture from the air inside, reducing humidity. However, the condensate from these dehumidifiers can still come into contact with electrical components, affecting the safety of the equipment. Utility Model Content

The condensation is eventually discharged through the drain outlet, thus separating it from the housing and reducing the possibility of condensate coming into contact with electrical components, thereby improving the safety of the electrical equipment. After condensation, the temperature of the high temperature and high humidity gas is also reduced, which helps to maintain the internal environment of the housing within a stable temperature range, preventing the operating environment temperature of electrical components from becoming too high and affecting their service life and stability.

[0032] 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.

[0033] 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.

[0034] This application provides a dehumidification device; please refer to [link / reference]. Figure 1 and Figure 2 A dehumidification device is used in electrical equipment. The electrical equipment includes a housing 7. The dehumidification device includes a condenser 1 and a refrigeration component 2. The condenser 1 is adapted to be installed on the outside of the housing 7. The condenser 1 has a condensation chamber 10 and an opening 11 and a drain outlet 12 communicating with the condensation chamber 10. The opening 11 is adapted to communicate with the internal space of the housing 7. The number of openings 11 can be one or more.

[0035] The refrigeration component 2 is connected to the condenser component 1 and is used to cool the refrigeration component 2 so that the temperature inside the condenser chamber 10 reaches the temperature at which moisture can condense.

[0036] The opening 11 of the condenser 1 can be directly or indirectly connected to the internal space of the housing 7. In the case of direct connection, a perforated structure or flow channel structure communicating with its internal space can be provided on the housing 7, with the opening 11 directly connected to the perforated structure or flow channel structure. In the case of indirect connection, the opening 11 of the condenser 1 and the housing 7 can be connected through a hollow solid structure, allowing the opening 11 to communicate with the internal space of the housing 7 through the hollow structure.

[0037] High-temperature, high-humidity gas inside the housing 7 enters the condenser chamber 10 through the opening 11. The cooling component 2 cools the condenser component 1, lowering the internal temperature of the condenser chamber 10. Water vapor condenses on the inner wall of the condenser chamber 10, falling under gravity and eventually draining through the drain outlet 12. This process dehumidifies the gas and separates the condensate from the housing 7. The dehumidified gas flows back into the housing 7, reducing the possibility of condensate coming into contact with electrical components, thus improving the safety of the electrical equipment. Furthermore, the temperature of the dehumidified gas is lowered to prevent excessively high internal temperatures within the housing 7, which could pose a safety hazard. In addition, the dehumidification device is essentially an external component of the electrical equipment, having minimal impact on its original structure. The device can also be easily and flexibly installed and removed as a whole.

[0038] Gas can flow between the housing 7 and the condensation chamber 10 through passive diffusion, or it can be driven by the turbulence fan of the electrical equipment itself for heat dissipation.

[0039] Please see Figure 3 In some embodiments, the condenser 1 includes a flow guiding surface 13 disposed within the condensation chamber 10. The flow guiding surface 13 includes a first section 131 connected to each other and a second section 132 disposed on at least one side of the first section. The second section 132 is configured to guide the liquid medium thereon to the first section 131. A drain outlet 12 is disposed on the first section 131, that is, the drain outlet 12 extends from the first section 131 to the outer wall surface of the condenser 1.

[0040] The guiding effect of the second section 132 can be achieved through the height difference between it and the first section 131, or through the surface structure. For example, the surface of the second section 132 can be coated with a hydrophobic coating, and the surface of the first section 131 can be coated with a hydrophilic coating, forming a gradient arrangement from hydrophobic to hydrophilic; or microgrooves can be etched on the surface of the second section 132, with the grooves pointing towards the first section 131, using capillary force to guide the droplets to flow towards the first section 131.

[0041] The flow guiding surface 13 is part of the inner wall surface of the condensation chamber 10. In this embodiment, a second section 132 is provided on each side of the first section 131 to expand the flow guiding range of the second section 132, so that the condensate water is collected on the first section 131, which facilitates the discharge of condensate water from the drain outlet 12 and reduces stagnation.

[0042] Please see Figure 3 In some embodiments, the first segment 131 is planar, and the second segment 132 extends along an arc-shaped trajectory. The opening 11 is correspondingly positioned on the side of the second segment 132 furthest from the first segment 131. The arc-shaped second segment 132 creates a height difference, allowing condensation to slide down the second segment 132 onto the first segment 131 under gravity, which is simple and convenient. When the second segment 132 is positioned at the corner of the condensation chamber 10, stress concentration on the condenser 1 can also be reduced. In other embodiments, the first segment 131 can also be arc-shaped, and its curvature can be the same as or different from that of the second segment 132. The drain outlet 12 is positioned at the lowest point of the first segment 131 to further accelerate the condensation speed. When the curvature of the first segment 131 and the curvature of the second segment 132 are the same, the first segment 131 and the second segment 132 can be joined to form a large arc surface, with the drain outlet 12 located at the lowest point of this large arc surface.

[0043] Please see Figure 4In some embodiments, the first segment 131 and the second segment 132 are planar, with the second segment 132 forming an obtuse angle with the first segment 131. The height difference between the second segment 132 and the first segment 132 allows condensation to flow towards the first segment 131 under gravity, resulting in a simple structure and easy manufacturing. In other embodiments, the first segment 131 may also be arc-shaped, with the drain outlet 12 located at the lowest point of the first segment 131.

[0044] In some embodiments, the remaining inner wall surfaces of the condensation cavity 10 may also be configured as the structure of the second section 132, so that the various surfaces surrounding the condensation cavity 10 avoid right angles at the corners, reduce eddies, and thus allow water vapor in the condensation cavity 10 to condense smoothly.

[0045] Please see Figure 2 and Figure 3 In some embodiments, the condenser 1 is provided with a plurality of condensing columns 3, which are located within the condensing cavity 10. The cross-section of the condensing column 3 is one of a circle, an ellipse, or a polygon. The condensing cavity 10 is formed by a plurality of surfaces, at least one of which is a flow guiding surface 13. The condensing columns 3 can be disposed on one or more of the plurality of surfaces. In this embodiment, the plurality of condensing columns 3 are distributed on two surfaces that are opposite to and adjacent to the flow guiding surface 13, and the area of ​​the two surfaces is larger than the area of ​​the other surfaces, so as to provide sufficient surface area to accommodate a greater number of condensing columns 3.

[0046] The condenser column 3 increases the surface area of ​​the condenser chamber 10, allowing more water vapor to come into contact with the low-temperature surface and liquefy, which helps to improve dehumidification efficiency.

[0047] Please see Figure 2 In some embodiments, the condenser 1 includes a first housing 14 and a second housing 15, which are connected to each other and form a condensation chamber 10.

[0048] At least one of the first housing 14 and the second housing 15 has a concave structure, and the two abut against each other to form a condensation chamber 10. In this case, the condensation columns 3 are respectively arranged on opposite sides of the first housing 14 and the second housing 15. The first housing 14 and the second housing 15 adopt a split structure, which can be processed and reassembled separately. This simplifies the processing technology and allows individual housing components to be interchanged before assembly, increasing the flexibility and versatility of the condenser 1. For example, the first housing 14 and the second housing 15 can be fixed by screws, bolts, riveting, welding, adhesive, or other structures.

[0049] Please see Figure 2In some embodiments, the dehumidification device further includes a pipe 16, which connects the condenser 1 and the housing 7 respectively, and communicates with the opening 11, so that the opening 11 communicates with the internal space of the housing 7 through the pipe 16. The pipe 16 realizes the indirect communication between the opening 11 and the internal space of the housing 7, and the connection requirements of the condenser 1 and the housing 7 at different relative positions can be met by the length and extension direction of the pipe 16, which is convenient and flexible for installation.

[0050] Please see Figure 2 and Figure 3 In some embodiments, the number of openings 11 is set to multiple, with each opening 11 corresponding to a pipe 16. The multiple openings 11 increase the gas flow path, thereby increasing the gas flow rate per unit time and accelerating the dehumidification speed.

[0051] In the plurality of openings 11, at least one opening 11 is an air inlet 111, and at least another opening 11 is an air outlet 112. Gas inside the housing 7 flows into the condenser chamber 10 through the air inlet 111, and dehumidified gas flows into the housing 7 through the air outlet 112, achieving gas circulation. In this embodiment, the air inlet 111 and the air outlet 112 are arranged opposite to each other about the condenser chamber 10, so that high-temperature and high-humidity gas flows through the entire condenser chamber 10, achieving sufficient condensation. In other embodiments, the air inlet 111 and the air outlet 112 may also be located on the same side of the condenser chamber 10, and arranged alternately.

[0052] Please see Figure 2 In some embodiments, the dehumidification device further includes a waterproof and breathable component 4, which is disposed at the opening 11 and connected to the condenser 1. Specifically, the waterproof and breathable component 4 is one of expanded polytetrafluoroethylene (ePTFE) membrane and waterproof and breathable valve, which allows normal air circulation while preventing condensate in the condensation chamber 10 from flowing back into the housing 7, thereby further improving the safety of the electrical equipment. The waterproof and breathable component 4 is located at the opening 11, which allows condensate to be concentrated in the condensation chamber 10 for rapid drainage, preventing condensate from stagnating in the pipe 16.

[0053] Please see Figure 1 and Figure 5 In some embodiments, the dehumidification device further includes a fan 5, which is adapted to be installed inside the housing 7 and positioned opposite one of the pipes 16. The fan 5 is used to force airflow, providing driving force to the airflow so that the airflow actively circulates for dehumidification, thereby improving dehumidification efficiency. The fan 5 can be matched with pipes 16 corresponding to different openings 11 depending on its different states.

[0054] For example, the fan 5 is positioned opposite the pipe 16 corresponding to the air inlet 111. At this time, the fan 5 blows air toward the pipe 16, drawing the airflow in the housing 7 into the pipe 16.

[0055] For example, the fan 5 is positioned opposite the pipe 16 corresponding to the air outlet 112. At this time, the fan 5 draws air towards the pipe 16, forcibly pulling the gas in the pipe 16 to flow into the housing 7.

[0056] Please see Figure 2 In some embodiments, the dehumidification device further includes a one-way valve 6, which is disposed on the condenser 1 and communicates with the drain port 12. The one-way valve 6 allows condensate to be discharged from the drain port 12, but prevents external air, water vapor or liquid from flowing back into the condenser chamber 10, ensuring humidity isolation between the inside and outside of the housing 7, which helps maintain the low temperature environment of the condenser chamber 10 and improves dehumidification efficiency.

[0057] In some embodiments, the cooling component 2 includes one of a semiconductor cooler, an air-cooled radiator, and a liquid-cooled radiator.

[0058] A thermoelectric cooler, also known as a Peltier cooler, is a solid-state refrigeration device based on the thermoelectric effect. It has a cold end and a hot end. The cold end is in contact with the condenser element 1, while the hot end is located on the side of the thermoelectric cooler away from the condenser element 1. The working principle of a thermoelectric cooler is as follows: when electrons flow from an N-type semiconductor to a P-type semiconductor, they absorb heat, causing the cold end temperature to drop; when electrons flow from a P-type semiconductor to an N-type semiconductor, they release heat, causing the hot end temperature to rise.

[0059] The air-cooled heat sink includes a heat dissipation base plate, fins, and an axial fan. The heat dissipation base plate is a heat-conducting plate made of metal (such as aluminum or copper), which is in close contact with the outer wall of the condenser 1, or connected to the outer wall of the condenser 1 through thermally conductive silicone. Multiple parallel metal fins are welded to the base plate. The axial fan is installed on one side of the fins to force air convection, and the airflow direction is parallel to the fins.

[0060] The liquid-cooled radiator includes an evaporator, a condenser, and a compressor, which are connected in series by a pipe 16. The evaporator is connected to the condenser 1 and uses a phase change working fluid to absorb the heat inside the condenser chamber 10 to achieve the purpose of cooling.

[0061] The refrigeration component 2 can be flexibly selected according to factors such as the size of the space where the electrical equipment is located and the ambient temperature of the working environment, in order to meet the usage requirements of different working conditions.

[0062] According to a second aspect of this disclosure, an electrical device is provided, including a housing 7 and the aforementioned dehumidification device, wherein the dehumidification device is disposed on the outside of the housing 7 and configured to dehumidify the interior space of the housing 7. This electrical device possesses all the beneficial effects of the aforementioned dehumidification device, which will not be elaborated further here.
