Description

Technical Field

[0001] This utility model relates to the field of moisture-proof ventilation technology for power distribution equipment, and in particular to a moisture-proof ventilation structure for indoor power distribution equipment. Background Technology

[0002] Indoor power distribution equipment usually refers to a collection of electrical components used for power distribution or protection of electrical equipment. It usually consists of an outer enclosure and several electrical components installed inside the enclosure.

[0003] Under normal operating conditions, electrical components generate a lot of heat. In order to dissipate the heat and prevent damage to the components, a ventilation device is installed inside. During operation, the ventilation device will exhaust the hot air inside and draw in the outside air to complete the ventilation and cooling.

[0004] However, the external air cannot be guaranteed to be completely dry. The air itself has a certain humidity. When excessively humid air enters the enclosure, it may cause the components to become damp and damaged during use, or even cause a short circuit.

[0005] To avoid this situation, operators will place a large amount of desiccant inside the chamber or at the air inlet to dehumidify the air entering the chamber. However, desiccant will quickly become ineffective when it comes into direct contact with humid air during use, requiring operators to frequently replace it. If the desiccant is not replaced in time, it may have the opposite effect, making the air even more humid. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this utility model is to provide a moisture-proof and ventilated structure for indoor power distribution equipment, thereby solving the problem that excessively humid air entering the enclosure directly can damage components.

[0007] The technical solution of this utility model is as follows: a moisture-proof and ventilation structure for indoor power distribution equipment, including a box with ventilation slots on both sides, an equipment box covering the ventilation slots on both sides of the box, ventilation holes arranged in a row on the surface of the equipment box, a condenser plate vertically inserted inside the equipment box, the top and bottom of the condenser plate extending to the outside of the equipment box, a heat dissipation plate at both ends of the condenser plate, a placement rack slidably connected inside the equipment box, and an air distribution plate between the placement rack and the condenser plate.

[0008] Furthermore, the condenser plate is composed of three sets of parallel V-shaped plates, with a gap between each pair of adjacent V-shaped plates. Gas flow channels are formed between the condenser plates along the gaps. The gaps between the three sets of V-shaped plates are staggered. The condenser plate can restrict the movement path of the air to ensure that the air can fully contact the condenser plate. In addition, the air can be repeatedly diverted during the movement of the air to slow down the air flow speed.

[0009] Furthermore, the two adjacent V-shaped plates in the condenser plate face opposite directions, making the air passage formed by the gap between the V-shaped plates Z-shaped, increasing the length of the air passage, increasing the contact area between the air and the condenser plate, and optimizing the condensation effect.

[0010] Furthermore, the V-shaped plates of the condenser plate near the ventilation hole have their tips facing the ventilation hole, and the V-shaped plates of the condenser plate near the heat sink have their openings facing the air distribution plate. The air entering through the ventilation hole will contact the condenser plate immediately to complete the diversion, and the air passing through the condenser plate will be gathered and contacted by the air distribution plate under the action of the condenser plate, so that the air distribution plate can evenly distribute the air.

[0011] Furthermore, both the condenser plate and the heat sink are made of aluminum. The heat sink consists of two parallel plates with a gap between them, allowing the condenser plate to better reduce the air temperature and the heat sink to better absorb and dissipate heat.

[0012] Furthermore, the placement rack is located on one side of the connection between the equipment box and the housing. The whole includes a rectangular frame and several horizontally mounted baffles within the frame. Gaps are left between the baffles, and moisture-absorbing filter material is filled in the gaps. The moisture-absorbing filter material is not fixed separately, which makes it convenient for operators to replace it.

[0013] Furthermore, a drain groove is provided at the bottom of the equipment box, and the drain groove is connected to the condenser plate to ensure that the liquid generated after condensation can leave the equipment box along the drain groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model covers the air inlet positions on both sides of the housing with a device box. Air first enters the device box and comes into contact with the condenser plate. Under the action of the heat sink, the temperature of the condenser plate is lower than that of the natural environment. When the air comes into contact with the condenser plate, the internal moisture will condense on the surface of the condenser plate, removing some of the moisture in the air. Then the air passes through the rack and comes into contact with the moisture-absorbing filter material set in the rack. When the air passes through the filter material again, the internal moisture is absorbed, further reducing the moisture content in the air. However, since the moisture in the air has been reduced by the condensation effect, the service life of the filter material is greatly extended. This ensures that the ventilation inside the housing can be carried out normally, preventing excessively humid air from entering the housing and affecting electronic components, while extending the service life of the filter material.

[0016] 2. In this utility model, the equipment box is completely set on the outside of the housing. The through groove at the bottom of the equipment box can ensure that the liquid droplets generated by condensation inside the equipment box can flow out and will not accumulate in the equipment box and affect the air. The shelf for fixing the moisture-absorbing filter material is slidably connected to the housing. When the filter material needs to be installed or removed, the operator can simply pull out the shelf. This simplifies the operation steps and does not affect or contact the electronic components inside the housing during use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figure 1-5 As shown, an indoor power distribution equipment moisture-proof ventilation structure includes a box 1 with ventilation slots on both sides, and an equipment box 2 covering the ventilation slots on both sides of the box 1. Ventilation holes 3 are arranged in a row on the surface of the equipment box 2. A condenser plate 4 is vertically inserted inside the equipment box 2. The condenser plate 4 is composed of several V-shaped plates in three sets of parallel V-shaped plates. There is a gap between each two adjacent V-shaped plates. The gaps between the condenser plates 4 form an air passage for air flow. The gaps between the three sets of V-shaped plates are staggered. The condenser plate 4 can restrict the movement path of the air to ensure that the air can fully contact the condenser plate. During the air movement, the air can be repeatedly diverted to slow down the air flow speed. The two adjacent V-shaped plates in the condenser plate 4 face opposite directions, so that the air passage formed by the gap between the V-shaped plates is Z-shaped, which increases the length of the air passage, increases the contact area between the air and the condenser plate 4, and optimizes the condensation effect. The top and bottom of the condenser plate 4 extend to the outside of the equipment box 2.

[0025] The bottom of the equipment box 2 is provided with a drain groove, which is connected to the condenser plate 4 to ensure that the liquid generated after condensation can leave the equipment box 2 along the drain groove. Both ends of the condenser plate 4 are provided with heat dissipation plates 5. The condenser plate 4 and the heat dissipation plates 5 are made of aluminum. The heat dissipation plate 5 is composed of two parallel plates with a gap between them, so that the condenser plate 4 can better reduce the air temperature. At the same time, the heat dissipation plate 5 can better absorb heat and dissipate it outward. A placement rack 6 is slidably connected inside the equipment box 2. The placement rack 6 is located on one side of the connection between the equipment box 2 and the box body 1. The whole includes a rectangular frame and several horizontally mounted baffles inside the frame. There are gaps between the baffles, and the gaps are filled with moisture-absorbing filter material. The moisture-absorbing filter material is not fixed separately, so it is convenient for operators to replace it.

[0026] An air distribution plate 7 is provided between the placement rack 6 and the condenser plate 4. The tips of a set of V-shaped plates near the ventilation hole 3 of the condenser plate 4 face the ventilation hole 3, and the openings of a set of V-shaped plates near the heat sink 5 face the air distribution plate 7. The air entering along the ventilation hole 3 will contact the condenser plate 4 immediately to complete the diversion. The air passing through the condenser plate 4 will be gathered and contact the air distribution plate 7 under the action of the condenser plate 4, so that the air distribution plate 7 can distribute the air evenly.

[0027] The working principle of this utility model is as follows: First, air enters the equipment box 2 through the ventilation hole 3. The air entering the equipment box 2 first comes into contact with the condenser plate 4. At the same time as the air comes into contact with the condenser plate 4, it is diverted due to the shape of the condenser plate 4 and gradually moves along the gap between the condenser plates 4. During the movement, the moisture in the air gradually condenses on the surface of the condenser plate 4. The condensed droplets flow downward and finally leave the equipment box 2 through the drain trough. After leaving the condenser plate 4, the air comes into contact with the air distribution plate 7. After passing through the air distribution plate 7, the air passes evenly through the placement rack 6 and through the moisture-absorbing filter material into the box 1. When the air passes through the moisture-absorbing filter material again, the moisture in the air is absorbed by the moisture-absorbing filter material again.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
