Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and in particular to an anti-condensation electrical control cabinet. Background Technology

[0002] Electrical control cabinets are widely used in industrial automation control systems, housing precision electrical components and circuit boards. In environments with large day-night temperature differences or high humidity, the temperature difference between the inside and outside of the cabinet may cause the surface temperature of the inner wall to fall below the dew point temperature of the ambient air, resulting in condensation. Condensation droplets falling or accumulating at the bottom of the cabinet can easily lead to short circuits, corrosion, and decreased insulation performance of electrical components, causing equipment malfunctions or even safety accidents, severely impacting the stable operation of the system.

[0003] In existing technologies, heaters or air conditioners are often installed inside the cabinet to raise the temperature and lower the humidity, thus preventing condensation. However, this method is energy-intensive and its effectiveness is limited under certain extreme conditions (such as when the cabinet is not properly sealed or when the environment changes abruptly). Another approach is to improve the cabinet structure, such as by adding drainage holes. However, this method cannot prevent dust and insects from entering the cabinet through the drainage holes, and condensation may still flow inside the cabinet before being discharged, posing a safety hazard.

[0004] Therefore, there is an urgent need for an electrical control cabinet structure that can efficiently and proactively collect and discharge condensation while also ensuring dustproof sealing. Summary of the Invention

[0005] The purpose of this application is to provide an anti-condensation electrical control cabinet to solve the above problems. It has a reasonable structure, a significant anti-condensation effect, and low energy consumption.

[0006] This application achieves the above objectives through the following technical solutions:

[0007] An anti-condensation electrical control cabinet includes a cabinet body and a cabinet door, characterized in that the cabinet body is provided with a condensation guiding structure, a condensation collection device and a condensation discharge device.

[0008] The condensation guiding structure is disposed on the inner surface of the cabinet and is used to guide the condensation condensed on its surface to the condensation collection device.

[0009] The condensation collection device is located at the end of the condensation flow path of the condensation guiding structure, and is used to receive and temporarily store condensation.

[0010] The condensation discharge device is connected to the condensation collection device and includes a heating component for heating the collected condensation to evaporate it and discharging the generated water vapor to the outside of the cabinet.

[0011] In some embodiments, the condensation guiding structure includes:

[0012] A V-shaped top structure located at the top of the cabinet is used to guide condensation from the top to its lowest point; and

[0013] The inclined structure, which slopes inward from high to low, is provided on the side wall of the cabinet to guide condensation on the side wall to its bottom.

[0014] In some embodiments, the condensation collection device includes:

[0015] A first condensation collection box for collecting top condensation extends along the length of the V-shaped top structure and is positioned below its lowest point; and

[0016] A second condensation collection box is provided at the bottom of both side walls of the cabinet for collecting condensation on the side walls.

[0017] In some embodiments, both the first and second condensation collection boxes partially penetrate the wall of the cabinet, with their ends extending to the outside being sealed ends;

[0018] The first and second dew collection boxes are respectively provided with a first absorbent strip and a second absorbent strip. The first and second absorbent strips are made of absorbent material and extend from the inside of the dew collection box to the sealed end.

[0019] In some embodiments, the interior of the first condensation collection box and the second condensation collection box are respectively provided with a first inclined surface and a second inclined surface, which are inclined from high to low toward their respective sealing ends, so as to guide the condensation or excess water absorbed in the absorbent strip to the sealing end.

[0020] In some embodiments, the condensation discharge device includes:

[0021] A first heater and a second heater, disposed at the sealed ends of the first and second condensation collection boxes, are used to heat the first and second absorbent strips extending thereto; and

[0022] The first steam pipe and the second steam pipe are provided at the sealed end. The first steam pipe and the second steam pipe are respectively provided with a first steam exhaust channel and a second steam exhaust channel that communicate with the inside of the condensation box, so as to exhaust the water vapor generated by heating to the outside of the cabinet.

[0023] In some embodiments, the first steam pipe and the second steam pipe are arranged in a horizontal direction.

[0024] In some embodiments, a guide plate is provided above the first dew collection box. The guide plate is arranged in a V-shape along both sides of the first dew collection box to receive the dew dripping from the top of the V-shape and guide it into the first dew collection box.

[0025] Compared to existing technologies, this application, through a unique structural design, first guides and collects the dispersed condensation to a specific collection point; then, a collection device temporarily stores the liquid water to prevent it from flowing around; finally, at a specific location within the collection device, low-power localized heating converts the liquid water into water vapor, which is then safely discharged outside the cabinet through a dedicated channel. This process achieves integrated "collection-guidance-discharge" treatment of condensation, fundamentally eliminating the hazards of condensation. Attached Figure Description

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0036] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to 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 of this application.

[0037] Example 1

[0038] refer to Figure 1-6 The anti-condensation electrical control cabinet of this embodiment mainly includes a rectangular cabinet body 1 and a cabinet door 2 hinged to its front. The internal space of the cabinet body 1 is used to install various electrical components (not shown). The core improvement of this application lies in the collection and drainage system for condensation inside the cabinet.

[0039] Specifically, the cabinet 1 has an internal condensation guiding structure. Further, the condensation guiding structure includes a V-shaped top structure at the top of the cabinet 1 and an inwardly sloping structure on the side wall of the cabinet 1. The V-shaped top structure allows dew condensed at the top to naturally converge and flow towards the lowest point in the center. The inwardly sloping side wall ensures that the condensation on the side wall flows along the slope to the bottom of the cabinet 1, rather than dripping randomly.

[0040] The condensation collection device is located at the end of the condensation flow path of the condensation guiding structure. In some embodiments, the condensation collection device includes a first condensation collection box 3 for collecting condensation from the top and a second condensation collection box 11 for collecting condensation from the side walls. The first condensation collection box 3 extends along the length of the V-shaped top structure and is precisely positioned directly below its lowest point to ensure complete collection of condensation flowing down from the V-shaped top. The second condensation collection box 11 is installed at the bottom of both side walls of the cabinet 1, its length covering the width of the cabinet side walls to completely collect condensation flowing down from the entire side wall.

[0041] The condensation discharge device is connected to the condensation collection device. Further, see... Figure 1 The first dew collection box 3 and the second dew collection box 11 both partially penetrate the wall of the cabinet 1, with their ends extending to the outside being sealed to prevent external dust and moisture from flowing back in. The first dew collection box 3 and the second dew collection box 11 are respectively equipped with a first absorbent strip 4 and a second absorbent strip 14. The first absorbent strip 4 and the second absorbent strip 14 are made of highly absorbent materials, such as microfiber cloth, sponge, or hydrophilic polymer materials, which not only absorb liquid water but also have a certain capillary water-conducting effect. The first absorbent strip 4 and the second absorbent strip 14 extend from the inside of the dew collection box to the sealed end.

[0042] Furthermore, to optimize the flow of water in the condensate or supersaturated absorbent strip, the first condensate collection box 3 and the second condensate collection box 11 are respectively provided with a first inclined surface 5 and a second inclined surface 13. The first inclined surface 5 and the second inclined surface 13 slope from high to low towards their respective sealing ends. This means that even if the amount of condensate is large and exceeds the instantaneous adsorption capacity of the absorbent strip, the liquid water will flow towards the sealing end along the first inclined surface 5 and the second inclined surface 13 under the action of gravity, creating favorable conditions for subsequent discharge.

[0043] The condensation discharge device further includes a heating element and a steam exhaust channel. In some preferred embodiments, the condensation discharge device includes a first heater 10 and a second heater 17 disposed at the sealed ends of the first condensation collection box 3 and the second condensation collection box 11, and a first steam guide pipe 7 and a second steam guide pipe 15 disposed at the sealed ends. The first heater 10 and the second heater 17 can be patch-type PTC heaters or resistance wires, and their positions are configured to directly contact the first water absorption strip 4 and the second water absorption strip 14 extending to the sealed ends. The first steam guide pipe 7 and the second steam guide pipe 15 are respectively provided with a first steam exhaust channel 9 and a second steam exhaust channel 16 communicating with the interior of the condensation collection box.

[0044] The working process is as follows: When condensation occurs inside the cabinet, the condensation at the top collects along the V-shaped top and drips down, where it is received by the first condensation collection box 3 and absorbed by the first absorbent strip 4; the condensation on the side walls flows down the slope to the bottom, where it is received by the second condensation collection box 11 and absorbed by the second absorbent strip 14. The absorbed moisture gradually accumulates towards the sealed end of the condensation collection box through capillary action and guided by the slope. When the first heater 10 and the second heater 17 are activated (which can be timed or controlled by a humidity sensor), they locally heat the ends of the absorbent strips that have accumulated moisture. Heating causes the moisture to evaporate rapidly into water vapor, which is then discharged into the atmosphere outside the cabinet 1 through the first exhaust channel 9 and the second exhaust channel 16, via the first steam guide pipe 7 and the second steam guide pipe 15. Because it is an exhaust gas, the channels can be made very small, and through clever structural design, it can effectively prevent the entry of external foreign objects.

[0045] Example 2

[0046] Based on Embodiment 1, to further enhance the dust prevention effect, in some embodiments, the first steam guide pipe 7 and the second steam guide pipe 15 are configured to extend horizontally. Horizontally positioned steam guide pipes can minimize the risk of airborne dust falling naturally into the exhaust channel under gravity, thereby preventing blockage or contamination of the condensate collection box and ensuring the long-term reliability of the system.

[0047] Example 3

[0048] refer to Figure 4Based on Embodiment 1 or 2, to ensure that the condensation dripping from the V-shaped top can accurately enter the first condensation collection box 3 and avoid splashing, a guide plate 8 is further provided above the first condensation collection box 3. The guide plate 8 extends upward along both sides of the first condensation collection box 3 and is arranged in a V-shape. The opening of the V-shaped guide plate 8 is directly opposite the lowest point of the V-shaped structure on the top of the cabinet, and can act like a funnel to completely catch any dripping water droplets and reliably guide them into the first cavity 6 of the first condensation collection box 3, thereby achieving 100% collection of the condensation at the top.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
