Description

Technical Field

[0001] This application relates to the field of power equipment dehumidification technology, and in particular to a novel power equipment box. Background Technology

[0002] Electrical equipment boxes, including switchgear and distribution cabinets, perform functions such as power distribution, control, and protection. In actual operation, due to the complex operating environment, the interior of electrical equipment boxes is easily affected by humidity, especially in humid, cold, or rainy environments. Moisture can enter the interior through tiny gaps in the switchgear, damaging the internal electronic components and insulation materials, as detailed below:

[0003] First, insulation materials are prone to moisture absorption and aging in humid environments, which reduces the overall insulation level of the switchgear and increases the risk of short circuits and leakage.

[0004] Secondly, metal components inside the power equipment box are prone to oxidation and corrosion in humid environments, which increases contact resistance, reduces power transmission efficiency, and may even cause local overheating.

[0005] In addition, excessive humidity may cause moisture in the air to come into contact with conductive parts, forming an electric arc discharge, which may lead to serious accidents such as short circuits and fires.

[0006] Therefore, dehumidifying the electrical equipment box is particularly important. Utility Model Content

[0007] To address the aforementioned technical problems, this application provides a novel power equipment box capable of dehumidifying the interior of the power equipment box.

[0008] This application provides a novel power equipment box, comprising:

[0009] The enclosure, dehumidifier unit, air pump, condenser, evaporator, and fan;

[0010] The dehumidification body is disposed inside the box and connected to the inner wall of the box. The dehumidification body is provided with a first channel and a second channel that are interconnected. The first channel and the second channel are separated by a condenser plate. The second channel is provided with a vent hole. The fan is disposed at the end of the dehumidification body and covers both the first channel and the second channel. The fan is used to control the airflow in the first channel and the second channel.

[0011] The evaporator is disposed in the first channel. One end of the evaporator is connected to the air inlet of the air pump, and the other end of the evaporator is connected to the condenser through a throttle valve. The condenser is connected to the air outlet of the air pump. The air pump is energized to drive the refrigerant to flow between the evaporator and the condenser.

[0012] Optionally, the condenser plate is provided with several baffles, so that water droplets formed on the condenser plate flow onto the baffles.

[0013] Optionally, some of the baffles are inclined downward at their ends along the airflow direction.

[0014] Optionally, the refrigerant is one of Freon, ammonia, trifluoromethane, and difluoromethane. Optionally, a controller and a hygrometer are installed inside the housing, with the controller electrically connected to both the hygrometer and the air pump. Optionally, an insulation layer is provided on the side of the first channel away from the second channel, and the insulation layer is connected to the first channel by adhesive. Optionally, the novel power equipment box also includes a battery and a solar charging panel. The battery is located at the bottom of the housing and connected to the air pump, while the solar charging panel is fixed to the outer surface of the housing and connected to the battery via a cable. Optionally, the fan is bolted to the dehumidification unit. Optionally, both the evaporator and the condenser are made of copper tubing. Optionally, a water outlet is provided at the bottom of the housing, communicating with both the first and second channels.

[0015] As can be seen from the above technical solutions, this application has the following effects:

[0016] This application involves installing a dehumidification body inside the enclosure. Within this body, a first channel and a second channel are interconnected and separated by a condenser plate. A vent is located on the second channel, allowing it to connect to the outside environment. A fan is positioned at the end of the dehumidification body, covering both the first and second channels. When the fan is activated, it controls the airflow within these channels. An evaporator is located within the first channel, with one end connected to the air pump inlet and the other end connected to the condenser via a throttling valve. The condenser is connected to the air pump outlet. The air pump is energized to drive the refrigerant to flow between the evaporator and condenser. When dehumidification is required, the air pump is energized, causing the refrigerant to flow between the evaporator and condenser. The refrigerant absorbs heat during evaporation in the evaporator, resulting in cooling at the evaporator location. This lowers the temperature within the first channel. When the fan blows air into the second channel, the moisture in the air condenses into water droplets on the condenser plate, thus removing moisture from the air.

[0017] Secondly, when the fan blows air into the first channel, it can also achieve the effect of cooling and dehumidifying the air.

[0018] In addition, cooling the air can effectively reduce the temperature inside the enclosure, preventing the temperature inside the electrical equipment enclosure from becoming too high. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] This application provides a novel power equipment box for dehumidifying its interior. The specific implementation process of this application is described below.

[0034] Please see Figures 1 to 7 The novel power equipment box provided in this application includes:

[0035] Cabinet 01, dehumidifier body 02, air pump 03, condenser 04, evaporator 05, and fan 06;

[0036] The dehumidifying body 02 is installed inside the cabinet 01 and connected to the inner wall of the cabinet 01. The dehumidifying body 02 is provided with a first channel 07 and a second channel 08 that are interconnected. The first channel 07 and the second channel 08 are separated by a condenser plate 09. The second channel 08 is provided with a vent hole 11. The fan 06 is installed at the end of the dehumidifying body 02 and covers both the first channel 07 and the second channel 08. The fan 06 controls the airflow in the first channel 07 and the second channel 08.

[0037] Evaporator 05 is installed in the first channel 07. One end of evaporator 05 is connected to the air inlet of air pump 03, and the other end of evaporator 05 is connected to condenser 04 through throttle valve 10. Condenser 04 is connected to air outlet of air pump 03. Air pump 03 is energized to drive refrigerant to flow between evaporator 05 and condenser 04.

[0038] The enclosure 01 is used to house and protect the internal electrical facilities and the dehumidification unit 02. The enclosure 01 is usually made of corrosion-resistant, high-strength metal or composite material to ensure the durability and safety of the enclosure 01.

[0039] Evaporator 05 is located in the first channel 07. Air pump 03 circulates refrigerant between evaporator 05 and condenser 04 through its air inlet. Throttling valve 10 allows the refrigerant to pass through a smaller pipe diameter. Therefore, when the refrigerant in condenser 04 passes through throttling valve 10, the temperature and pressure of the refrigerant decrease, allowing the refrigerant to vaporize more fully in evaporator 05, thereby absorbing more heat and achieving a cooling effect. The absorbed heat comes from the humid and hot air inside the cabinet 01, thus achieving dehumidification and cooling effects inside the cabinet 01.

[0040] Air pump 03 draws refrigerant into evaporator 05 through air inlet and sprays it into condenser 04 through air outlet, thereby realizing the circulation of refrigerant between evaporator 05, condenser 04 and air pump 03.

[0041] The dehumidifier body 02 is installed inside the housing 01 and is tightly connected to the inner wall of the housing 01 to reduce the possibility of moisture escape. The dehumidifier body 02 has a first channel 07 and a second channel 08, separated by a condenser plate 09. A fan 06 is located at the end of the dehumidifier body 02 and covers the first channel 07 and the second channel 08. When the fan 06 is powered on, it blows air from inside the housing 01 towards the first channel 07 and the second channel 08. A vent 11 is provided on the second channel 08, allowing air entering the second channel 08 to be discharged into the housing 01 through the vent 11. Since the first channel 07 and the second channel 08 are connected, air from both channels can be discharged through the vent 11. Thus, air flows from the housing 01 through the fan 06 into the first channel 07 and the second channel 08, and then back into the housing 01 through the vent 11, forming an air circulation. The airflow direction inside the housing 01 is as follows: Figure 2 As indicated by the middle arrow.

[0042] In this cycle, the refrigerant evaporates and absorbs heat in the evaporator 05, causing the temperature in the first channel 07 to drop. As a result, the warmer and more humid air from the casing 01 enters the first channel 07 and condenses into water droplets on the evaporator 05 or on the inner wall of the first channel 07, thus reducing the moisture content of the air and achieving dehumidification. Furthermore, since the first channel 07 and the second channel 08 are separated by a condenser plate 09, which has a heat transfer process, the temperature in the second channel 08 also drops as the temperature in the first channel 07 decreases. Therefore, when air enters the second channel 08, the second channel 08 also performs condensation and dehumidification.

[0043] The dehumidification principle of this application is as follows: When the power equipment box is started and dehumidification is required, the air pump 03 starts working, driving the refrigerant to circulate between the evaporator 05 and the condenser 04. The humid and hot air inside the box 01 enters the first channel 07 and the second channel 08 simultaneously through the action of the fan 06. Due to the cooling effect of the evaporator 05, the first channel 07 and the second channel 08 are cooled down. When the humid and hot air encounters the cooler inner walls of the first channel 07 and the second channel 08, as well as the condenser plate 09, the moisture in the air condenses onto the inner walls of the first channel 07 and the second channel 08, as well as the condenser plate 09, thereby achieving dehumidification of the air. Subsequently, the dry air is discharged through the vent 11 and re-enters the box 01, thus maintaining the dry environment inside the box 01.

[0044] In one optional embodiment, a plurality of baffles 12 are provided on the condenser plate 09, so that water droplets formed on the condenser plate 09 flow onto the baffles 12. In this embodiment, with baffles 12 provided on the condenser plate 09, the temperature of the condenser plate 09 also decreases under the premise of cooling in the first channel 07. Therefore, when it encounters the humid and hot air inside the chamber 01 in the second channel 08, the moisture in the humid and hot air condenses into water droplets on the condenser plate 09. The water droplets flow onto the baffles 12 under the action of gravity, thereby achieving water droplet collection. In addition, the baffles 12 are connected to the condenser plate 09, and the temperature of the baffles 12 themselves also decreases, so the moisture in the air also condenses on the baffles 12. By providing a plurality of baffles 12, the contact area with the air is increased, thereby improving the dehumidification efficiency.

[0045] In this optional embodiment, several baffles 12 are inclined downwards at their ends along the airflow direction. In this embodiment, all baffles 12 are inclined, allowing water droplets flowing onto the baffles 12 to flow downwards along the slope of the baffles 12. When they reach the end of the baffles 12, they fall downwards to the bottom of the first channel 07, achieving collection. Because the baffles 12 are inclined downwards at their ends along the airflow direction, the water droplets on the condenser plate 09 and the baffles 12 move faster under the action of the fan 06.

[0046] In an optional embodiment, a water outlet 13 is provided at the bottom of the tank 01, and the water outlet 13 is connected to the first channel 07 and the second channel 08 respectively. In this embodiment, by providing the water outlet 13, the collected water can be discharged outside the tank 01, thereby ensuring the dryness inside the tank 01 and preventing water residue inside the tank 01 from causing pollution.

[0047] In one optional embodiment, the refrigerant is one of Freon, ammonia, trifluoromethane, and difluoromethane.

[0048] In an optional embodiment, a controller 14 and a hygrometer 15 are installed inside the housing 01. The controller 14 is electrically connected to the hygrometer 15 and the air pump 03. In this embodiment, by setting the hygrometer 15, the humidity inside the housing 01 can be monitored in real time. The controller 14 is electrically connected to the air pump 03 and the fan 06. A humidity threshold can be set in the controller 14. When the hygrometer 15 detects that the humidity inside the housing 01 reaches the humidity threshold, the controller 14 automatically triggers the dehumidification operation, that is, the controller 14 controls the fan 06 and the air pump 03 to start, so as to realize the automatic dehumidification of the housing 01.

[0049] In an optional embodiment, an insulation layer is provided on the side of the first channel 07 away from the second channel 08, and the insulation layer is connected to the first channel 07 by adhesive. In this embodiment, by providing an insulation layer, heat loss from the side of the first channel away from the second channel 08 can be reduced, ensuring that the temperature in both the first channel 07 and the second channel 08 is sufficiently low, thus ensuring the dehumidification effect. The insulation layer can be insulation cotton, phenolic insulation board, or glass wool.

[0050] In an optional embodiment, the application further includes a storage battery 17 and a solar charging panel. The storage battery 17 is disposed at the bottom of the housing 01 and connected to the air pump 03. The solar charging panel is fixed to the outer surface of the housing 01 and connected to the storage battery 17 via a cable.

[0051] The battery 17 is also electrically connected to the fan 06. The battery 17 is used to provide power to the air pump 03 and the fan 06. The solar charging panel is installed on the outer surface of the housing 01 and in a position that can be exposed to sunlight. When exposed to sunlight, the solar charging panel charges the battery 17.

[0052] The solar charging panel can be connected to the outer surface of the housing 01 by bolts or clips, so that it can be disassembled at will.

[0053] In an optional embodiment, the fan 06 is bolted to the dehumidification body.

[0054] In an optional embodiment, both the evaporator 05 and the condenser 04 are made of copper tubing. To ensure the cooling effect of the evaporator 05, the evaporator 05 is formed by bending the copper tubing several times to increase the cooling area.

[0055] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application.
