Description

Technical Field

[0001] The present invention belongs to the technical field of electrical cabinets, and more specifically, particularly relates to an electrical cabinet with heat dissipation and dehumidification functions. Background Art

[0002] As an important carrier of electrical equipment, electrical cabinets are widely used in many fields such as industrial production, power systems, and communication rooms. They provide installation, protection, and operating environment for various electrical components, and play a key role in ensuring the stable operation of electrical systems. In practical applications, electrical cabinets usually cover the following key parts: 1. Cabinet shell: generally made of metal materials, such as steel plates, which are durable and shield against electromagnetic interference, and protect internal electrical components from external physical impact, dust pollution, and a certain degree of electromagnetic interference; 2. Mounting bracket: used to fix various electrical components to ensure their stable position inside the cabinet, convenient for wiring and maintenance. Different bracket designs can adapt to electrical components of various specifications; 3. Wiring terminals: responsible for the connection and transfer of electrical circuits, realizing the electrical connection between various electrical components and between electrical cabinets and external equipment, ensuring smooth and safe current transmission; 4. Control switch: It is convenient for operators to start and stop the electrical system and control the operating status of electrical equipment. It also has overload, short circuit and other protection functions to prevent safety accidents caused by electrical failures.

[0003] At present, in order to meet the basic functional requirements of electrical cabinets, many manufacturers have developed various types of electrical cabinet products. Some manufacturers focus on improving the protection level of the cabinet, adopting a sealed design and installing multiple layers of dustproof and waterproof rubber strips to ensure that the internal electrical components are not affected by the harsh environment; some manufacturers make a fuss about the cabinet structure design and launch modular electrical cabinets. Through the combination of standardized modules, it is convenient for users to quickly build and adjust the electrical system according to actual needs; some other manufacturers focus on the intelligence of electrical cabinets, with built-in intelligent monitoring modules that can monitor parameters such as temperature, humidity, current, voltage, etc. in real time, and transmit data remotely to realize intelligent operation and maintenance of electrical cabinets.

[0004] However, the above-mentioned existing electrical cabinet technology still has many problems to be solved. In terms of heat dissipation, as the integration of electrical components becomes higher and higher and the power continues to increase, traditional electrical cabinets can no longer meet the demand by relying only on simple ventilation holes and fans for heat dissipation, which often leads to excessive temperature in the cabinet, accelerates the aging of electrical components, shortens their service life, and even causes overheating failures, causing the electrical system to shut down, resulting in serious consequences such as production interruption; in terms of dehumidification, when the electrical cabinet is in a humid environment, such as a basement, a machine room in coastal areas, etc., moisture can easily invade the cabinet, and the dehumidification measures of existing electrical cabinets are often not effective enough. The dehumidification capacity of a simple desiccant is limited and cannot be continuously dehumidified, while ventilation and dehumidification may introduce more moisture. A humid environment can easily cause corrosion and short circuit of electrical components, which also threatens the safety and stable operation of the electrical system. In response to these problems, this application proposes an innovative solution to design an electrical cabinet with efficient heat dissipation and strong dehumidification functions. The electrical cabinet can quickly reduce the temperature in the cabinet, effectively remove moisture, provide an excellent operating environment for electrical components, and ensure the continuous and stable operation of the electrical system.

[0005] In view of this, the existing structure and defects are studied and improved, and an electrical cabinet with heat dissipation and dehumidification functions is provided, in order to achieve a more practical purpose. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides an electrical cabinet with heat dissipation and dehumidification functions to solve the above problems.

[0007] An electrical cabinet with heat dissipation and dehumidification functions comprises an electrical cabinet body, a water storage box is fixedly connected to the electrical cabinet body, a separation box is fixedly connected to the upper surface of the water storage box, a cooling pipe is movably connected to the inner wall of the electrical cabinet body and a water pump is fixedly installed, a cylinder and a return plate are fixedly installed on the upper surface of the electrical cabinet body, a fixing frame is movably connected to the upper surface of the electrical cabinet body, two cooling fans are fixedly installed in the fixing frame, a spiral tube is arranged above the electrical cabinet body, a fan is fixedly installed on the left surface of the separation box, a connecting frame is fixedly connected to the upper surface of the separation box, a group of diverter plates are fixedly connected to the inner wall of the separation box, a group of the diverter plates are fixedly connected to a fiber layer, a group of the diverter plates are fixedly connected to the lower surface of a group of the diverter plates, two sliders are fixedly connected to the lower surface of the fixing frame and a fixing plate is fixedly connected to the front surface, and the fixing plate is fixedly connected to the cylinder piston.

[0008] Preferably, a card slot is provided on the upper surface of the electrical cabinet body, and the card slot is movably connected to the two sliders. Two connecting tubes are fixedly connected between the cooling tube and the spiral tube. The connecting tube and the spiral tube on the left of the two connecting tubes are fixedly connected to the output ends on both sides of the water pump, and a connecting net is fixedly connected in the separation box.

[0009] Preferably, a protective net is fixedly connected inside the connecting frame, a water outlet pipe is fixedly connected to the left surface of the water storage box, the water outlet pipe is movably connected to the electrical cabinet body, a valve is provided on the surface of the water outlet pipe, and air supply pipes are fixedly connected to the output ends on both sides of the fan.

[0010] Preferably, the two air ducts are fixedly connected to the connecting frame and the separation box respectively, and a group of circular holes are opened on the inner wall of a group of diverter plates.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the protective net is used to filter larger particulate impurities to prevent them from entering the ventilation system. The inhaled air hits a group of diverter plates at a certain speed. The arrangement of the group of diverter plates changes the flow direction of the air, allowing the air to shuttle between the diverter plates. This flow mode increases the contact time and area between the air and the diverter plates. The fiber layer arranged in the diverter plate can absorb liquid in the air. When humid air passes through the fiber layer, water vapor molecules will be absorbed by the fiber surface, thereby achieving a dehumidification effect.

[0012] In the present invention, the wind blown out by the cooling fan directly acts on the spiral tube, accelerating the air flow on the surface of the spiral tube, prompting the heat in the coolant to be quickly dissipated into the air. The return plate arranged behind the spiral tube can block a part of the airflow that directly passes through the spiral tube after being blown out by the cooling fan, causing it to change direction, thereby forming a relatively stable airflow circulation area between the spiral tube and the return plate, prolonging the contact time between the air and the spiral tube, and further improving the heat dissipation efficiency.

[0013] In the present invention, a fixing plate fixed on a fixing frame is connected with a cylinder piston, and the fixing frame is driven to move back and forth in a straight line by starting the cylinder. The fixing frame is movably connected with the electrical cabinet body through two sliding blocks fixed thereon. When the fixing frame moves, wind blown by two cooling fans arranged thereon can cover different areas of the spiral tube, thereby achieving uniform heat dissipation of the spiral tube, improving the heat dissipation effect, preventing performance degradation or failure of electrical components caused by local overheating in the electrical cabinet body, and extending the overall service life of the electrical components.

DETAILED DESCRIPTION

[0016] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

The fixed plate 10 is fixedly connected to the piston of the cylinder 4. During use, the fan 18 is first started to absorb the air in the electrical cabinet body 1 through the air supply pipe 17 and the protective net 20. The protective net 20 plays a role in filtering larger particles of impurities to prevent them from entering the ventilation system. The inhaled air hits a group of diverter plates 21 at a certain speed. The arrangement of a group of diverter plates 21 changes the flow direction of the air, so that the air shuttles between the diverter plates 21. This flow mode increases the contact time and area between the air and the diverter plates 21. The fiber layer 23 arranged in the diverter plate 21 can absorb liquid in the air. When humid air passes through the fiber layer 23, water vapor molecules will be absorbed by the fiber surface, thereby achieving a dehumidification effect.

[0018] A card slot 6 is provided on the upper surface of the electrical cabinet body 1, and the card slot 6 is movably connected to the two sliders 11. Two connecting pipes 13 are fixedly connected between the cooling pipe 9 and the spiral pipe 7. The connecting pipe 13 on the left and the spiral pipe 7 are fixedly connected to the output ends of the water pump 25 on both sides. A connecting net 14 is fixedly connected in the separation box 2. A group of conical columns 22 fixedly connected to the lower surface of the diverter plate 21 can collect droplets. When the moisture absorbed by the fiber layer 23 accumulates to a certain extent, droplets will be formed. Under the action of gravity, these droplets pass through a group of The air flows through the circular hole 24 along the lower surface of the diverter plate 21 to the conical column 22, and then converges together and is discharged through the outlet pipe 15. Compared with the simple ventilation and dehumidification method, the structure of this scheme can make better use of the contact between air and dehumidification material to improve the dehumidification efficiency. The baffle changes the flow direction of the air, so that the air forms a complex flow path in the system and is more evenly distributed. The moisture in the air is effectively removed through the fiber layer 23, which helps to maintain a dry environment in the electrical cabinet and reduce problems such as damage to electrical components and short circuits caused by moisture.

[0019] A protective net 20 is fixedly connected to the connecting frame 19, a water outlet pipe 15 is fixedly connected to the left surface of the water storage box 3, the water outlet pipe 15 is movably connected to the electrical cabinet body 1, a valve 16 is arranged on the surface of the water outlet pipe 15, and air supply pipes 17 are fixedly connected to the output ends on both sides of the fan 18, and the two air supply pipes 17 are respectively fixedly connected to the connecting frame 19 and the separation box 2, and a group of circular holes 24 are opened on the inner wall of a group of branch plates 21. The cooling pipe 9 arranged in the electrical cabinet body 1 and the spiral tube 7 arranged above are connected by a water pump 25 to form a closed circulation system. After the water pump 25 is started, the coolant starts to flow in the spiral tube 7 and the cooling pipe 9. The initial temperature of the coolant is relatively low, which can absorb the heat in the electrical cabinet body 1. During the cooling process, the spiral design of the spiral tube 7 increases the contact area and residence time between the coolant and the external environment. When the heat in the electrical cabinet body 1 is absorbed by the coolant, the high-temperature coolant flows into the spiral tube 7. At this time, the cooling fan 5 arranged on the electrical cabinet body 1 is started, and the heat dissipation wind The wind blown out by the fan 5 directly acts on the spiral tube 7, accelerating the air flow on the surface of the spiral tube 7, and prompting the heat in the coolant to be quickly dissipated into the air. The return plate 8 arranged behind the spiral tube 7 can block a part of the airflow that directly passes through the spiral tube 7 after being blown out by the cooling fan 5, causing it to change direction, and forming a relatively stable airflow circulation area between the spiral tube 7 and the return plate 8, thereby prolonging the contact time between the air and the spiral tube 7 and further improving the heat dissipation efficiency. The fixed plate 10 fixed on the fixed frame 12 is connected to the piston of the cylinder 4. By starting the cylinder 4, the fixed frame 12 will be driven to move back and forth in a straight line. The fixed frame 12 is movably connected to the electrical cabinet body 1 through two sliders 11 fixed thereon. When the fixed frame 12 moves, the wind blown out by the two cooling fans 5 arranged thereon can cover different areas of the spiral tube 7, thereby achieving uniform heat dissipation of the spiral tube 7, improving the heat dissipation effect, preventing the performance degradation or failure of electrical components caused by local overheating in the electrical cabinet body 1, and prolonging the overall service life of the electrical components.

[0020] Working principle: The first step is to start the fan 18 during use, and absorb the air in the electrical cabinet body 1 through the air supply pipe 17 and the protective net 20. The protective net 20 plays a role in filtering larger particles of impurities to prevent them from entering the ventilation system. The inhaled air hits a group of diverter plates 21 at a certain speed. The arrangement of a group of diverter plates 21 changes the flow direction of the air, so that the air shuttles between the diverter plates 21. This flow mode increases the contact time and area between the air and the diverter plates 21. The fiber layer 23 arranged in the diverter plate 21 can absorb liquid in the air. When the humid air passes through the fiber layer 23, the water vapor molecules will be absorbed by the fiber surface, thereby achieving the dehumidification effect. A fixed connection on the lower surface of the diverter plate 21 The group of conical columns 22 can collect droplets. When the moisture adsorbed by the fiber layer 23 accumulates to a certain level, droplets will be formed. Under the action of gravity, these droplets pass through a group of circular holes 24 and flow along the lower surface of the diverter plate 21 to the conical columns 22, and then converge together and are discharged through the outlet pipe 15. Compared with the simple ventilation and dehumidification method, the structure of this scheme can make better use of the contact between air and dehumidification materials to improve the dehumidification efficiency. The baffle changes the flow direction of the air, so that the air forms a complex flow path in the system and is more evenly distributed. The fiber layer 23 effectively removes moisture from the air, which helps to maintain a dry environment in the electrical cabinet and reduce problems such as damage to electrical components and short circuits caused by moisture.

[0021] In the second step, the cooling pipe 9 arranged in the electrical cabinet body 1 and the spiral tube 7 arranged above are connected through the water pump 25 to form a closed circulation system. After the water pump 25 is started, the coolant begins to flow in the spiral tube 7 and the cooling pipe 9. The initial temperature of the coolant is relatively low, which can absorb the heat in the electrical cabinet body 1. During the cooling process, the spiral design of the spiral tube 7 increases the contact area and residence time between the coolant and the external environment. When the heat in the electrical cabinet body 1 is absorbed by the coolant, the high-temperature coolant flows into the spiral tube 7. At this time, the cooling fan 5 arranged on the electrical cabinet body 1 is started, and the wind blown by the cooling fan 5 directly acts on the spiral tube 7, accelerating the air flow on the surface of the spiral tube 7, prompting the heat in the coolant to be quickly dissipated into the air. The return plate 8 arranged behind the spiral tube 7 can block Block a part of the airflow that directly passes through the spiral tube 7 after being blown out from the cooling fan 5, change its direction, form a relatively stable airflow circulation area between the spiral tube 7 and the return plate 8, prolong the contact time between the air and the spiral tube 7, and further improve the heat dissipation efficiency. The fixing plate 10 fixed on the fixing frame 12 is connected to the piston of the cylinder 4. By starting the cylinder 4, the fixing frame 12 will be driven to move back and forth in a straight line. The fixing frame 12 is movably connected to the electrical cabinet body 1 through two sliding blocks 11 fixed thereon. When the fixing frame 12 moves, the wind blown by the two cooling fans 5 arranged thereon can cover different areas of the spiral tube 7, achieve uniform heat dissipation of the spiral tube 7, improve the heat dissipation effect, prevent the performance degradation or failure of electrical components caused by local overheating in the electrical cabinet body 1, and extend the overall service life of the electrical components.
