Description

Technical Field

[0001] This invention relates to the field of high and low voltage switchgear technology, and specifically to an intelligent dehumidification and heat dissipation device for high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is an electrical device used in power systems, primarily for controlling, protecting, and distributing electrical energy. The electrical equipment inside high and low voltage switchgear is highly sensitive to humidity. Excessive humidity can degrade the insulation performance of insulating materials, potentially leading to short circuits, leakage, and other faults. Keeping the switchgear dry can improve the reliability and stability of the electrical equipment. Furthermore, high and low voltage switchgear generates heat during operation, especially under high loads. If this heat cannot be dissipated promptly, the equipment temperature will rise, affecting its performance and lifespan. Overheated equipment may even cause fires and other safety accidents. Therefore, timely heat dissipation can improve equipment safety.

[0003] Chinese invention patent CN116345333B discloses a dehumidification and heat dissipation device for high and low voltage switchgear. In operation, the heat dissipation component draws cooled air into the cavity, and then, in conjunction with the operation of a fan in the dehumidification component, the cooled air enters and exits the cavity. During this process, the cooled air exchanges heat with the switchgear body, achieving heat dissipation. Regarding the aforementioned technology, the inventors believe the following drawbacks exist: Drawing outside air into the heat dissipation component for cooling, and then allowing the cooled air to exchange heat with the switchgear body, requires continuous circulation of outside air, which easily leads to the loss of cooled air inside the switchgear, resulting in high energy consumption for cooling. Furthermore, drying moisture through heating affects the heat dissipation of the switchgear, easily causing the temperature of electrical equipment to rise and thus damage. Summary of the Invention

[0008] Preferably, the flipping mechanism includes a lifting rod slidably mounted on the outside of the cabinet, and the lifting rod is controlled to rise and fall by a telescopic rod; Both ends of the lifting rod are equipped with racks, and one end of each of the two air intake boxes is connected to a gear via a rotating shaft. The two gears are respectively meshed with the two racks.

[0009] Preferably, the cabinet is provided with a ventilation component on the outside, and the ventilation component is located between two air inlets. The ventilation component is controlled to open or close by a lifting rod. The ventilation assembly includes a ventilation port on the cabinet, the ventilation port is provided with dustproof cotton, and the outside of the ventilation port is sealed by a sealing plate.

[0010] Preferably, a drive mechanism for controlling the operation of the two cross-flow fans is provided on one side of the outer casing; The drive mechanism includes a motor for driving one of the cross-flow fans to rotate, and both cross-flow fans are provided with a synchronous pulley at one end, and the two synchronous pulleys are connected by a synchronous belt drive.

[0011] Preferably, the evaporator is provided with a water storage component at the bottom, the water storage component includes a water leakage plate located at the bottom of the dehumidification and cooling zone, and a water baffle is provided around the upper part of the water leakage plate; The bottom of the drain plate is provided with a water collection area, and a level gauge is installed inside the water collection area; A drain pipe is provided on one side of the bottom of the water collection area, and the drain pipe is opened or closed by a drain valve.

This prevents the loss of low-temperature, low-humidity air inside the cabinet, thus saving energy. By setting up two exhaust vents at the top and bottom, the low-temperature, low-humidity air can be discharged more evenly, making the heat dissipation and dehumidification inside the cabinet more uniform. The trumpet-shaped exhaust vents and baffles further improve the uniformity of the exhaust air. When ventilation is required inside the cabinet, the air intake box is rotated 180 degrees by the flipping mechanism, so that the air intake mechanism can draw in air from outside the cabinet, and then blow air into the cabinet by the blower. At the same time as the air intake box flips, the ventilation port is opened, and the air inside the cabinet can be discharged through the ventilation port, thus completing the ventilation work of the cabinet. Moisture in the air turns into water droplets through the evaporator and is collected by the water storage component. The collected water flows into the water box on the back of the condenser through the drain pipe. At this time, the water temperature is low, which can improve the heat dissipation effect of the condenser. When the water vaporizes, it will be discharged through the water inlet. The vaporization of the water will also carry away heat, which can further improve the heat dissipation effect of the condenser. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-6 The present invention provides a technical solution: an intelligent dehumidification and heat dissipation device for high and low voltage switch cabinets, including a cabinet body 1. Two air inlets 21 are provided on one side of the cabinet body 1. The two air inlets 21 are switched by an air intake mechanism 2 to draw in air from inside the cabinet body 1 or from outside the cabinet body 1. Two exhaust vents 31 are provided on the other side of the cabinet body 1. The two exhaust vents 31 are connected to a blower mechanism 3 and blow air into the cabinet body 1 through the blower mechanism 3. The air intake mechanism 2 is connected to the blower mechanism 3 through two air intake pipes 4. The blower mechanism 3 includes a housing 32 that is sealed to the outside of the cabinet 1. A dehumidification and cooling zone 33 is provided in the middle of the inner side of the housing 32. One end of the air inlet pipe 4 is connected to one side of the dehumidification and cooling zone 33. An opening is provided on the other side of the dehumidification and cooling zone 33, and the opening is connected to two air ducts 34. An evaporator 51 for dehumidification and cooling is fixedly installed inside the dehumidification and cooling zone 33. The evaporator 51 provides low temperature through the refrigeration equipment 5. Two cross-flow fans 35 are rotatably installed at both ends of the housing 32. The air inside the dehumidification and cooling zone 33 is dehumidified and cooled by the evaporator 51, and then drawn into the cabinet 1 through the two air ducts 34 by the two cross-flow fans 35. The air is then blown into the cabinet 1 through the exhaust port 31. The exhaust port 31 is funnel-shaped, and multiple baffles 36 for changing the air direction are provided inside the exhaust port 31.

[0020] During normal dehumidification and heat dissipation operation, the air intake mechanism 2 draws in air from inside the cabinet 1, such as... Figure 3-5 Air from inside cabinet 1 enters through air inlet 21 and flows through two air intake pipes 4 into dehumidification and cooling zone 33. The evaporator 51 inside dehumidification and cooling zone 33 is cooled by refrigeration equipment 5, maintaining a low temperature. As the air passes through the low-temperature evaporator 51, its temperature decreases, and moisture in the air condenses into water droplets that adhere to the evaporator 51, further reducing humidity. This results in low-temperature, low-humidity air. Two cross-flow fans 35 rotate simultaneously, allowing the low-temperature, low-humidity air to pass through two fans on one side of dehumidification and cooling zone 33. The air duct 34 is drawn in by two cross-flow fans 35 and discharged into the cabinet 1 through the exhaust port 31. The air drawn in from the cabinet 1 is cooled and dehumidified before being discharged into the cabinet 1, forming an internal circulation of dehumidification and cooling. This prevents the loss of low-temperature and low-humidity air inside the cabinet 1, thus saving energy. By setting two exhaust ports 31 at the top and bottom, the low-temperature and low-humidity air can be discharged more evenly, making the heat dissipation and dehumidification inside the cabinet 1 more uniform. The horn-shaped exhaust port 31 and the baffle 36 further improve the uniformity of the exhaust air from the exhaust port 31.

[0021] The cabinet 1 is equipped with multiple temperature and humidity sensors 11, and both air inlet pipes 4 are equipped with solenoid valves 41, which are located on one side of the air inlet 21.

[0022] The internal temperature of cabinet 1 varies due to factors such as contact resistance, material differences, and uneven current distribution. When the temperature and humidity sensor 11 detects that the temperature in the upper part of cabinet 1 is high, the solenoid valve 41 of the lower air intake pipe 4 is closed. During air intake, the gas can only enter from the upper air intake port 21, which accelerates the intake of air in the upper part of cabinet 1 into the air intake port 21. Then, the air enters the dehumidification and cooling zone 33 through the upper air intake pipe 4, which can quickly achieve the cooling effect of the upper part of the zone.

[0023] A drive mechanism 8 for controlling the operation of two cross-flow fans 35 is provided on one side of the outer casing 32. The drive mechanism 8 includes a motor 81 for driving one of the cross-flow fans 35 to rotate. Both cross-flow fans 35 are provided with a synchronous pulley 82 at one end, and the two synchronous pulleys 82 are connected by a synchronous belt 83.

[0024] The synchronous pulley 82 and synchronous belt 83 on one side of the cross-flow fan 35 enable the motor 81 to drive the two cross-flow fans 35 to rotate simultaneously, so that the output power of the two cross-flow fans 35 is the same. Therefore, the air volume output from the exhaust port 31 is basically the same, which further improves the cooling and dehumidification effect inside the cabinet 1.

[0025] The air intake mechanism 2 includes two air intake boxes 22 rotatably mounted on two air intake ports 21. The air intake boxes 22 are shell structures. Both air intake boxes 22 are rotated by a flipping mechanism 6. The upper and lower ends of the air intake boxes 22 are arc-shaped structures. The upper and lower ends of the inner side of the air intake port 21 are provided with arc surfaces that match the upper and lower ends of the air intake boxes 22. One side of the air intake box 22 is provided with an opening, and the opening is provided with a detachable dustproof mesh plate 23. One side of the dustproof mesh plate 23 is provided with a dustproof cotton 24, and the dustproof cotton 24 is located inside the air intake box 22. The upper and lower sides of the air intake box 22 are provided with air intake slots 25, one of which is connected to one end of the air intake pipe 4. The flipping mechanism 6 includes a lifting rod 62 that is slidably installed on the outside of the cabinet 1. The lifting rod 62 is controlled to lift and lower through a telescopic rod 61. Both ends of the lifting rod 62 are provided with racks 63. One end of each of the two air inlet boxes 22 is connected to a gear 64 through a rotating shaft. The two gears 64 are respectively meshed with the two racks 63. A ventilation assembly 7 is provided on the outside of the cabinet 1, and the ventilation assembly 7 is located between two air inlets 21. The ventilation assembly 7 is controlled to open or close by a lifting rod 62. The ventilation assembly 7 includes a ventilation port 71 opened on the cabinet 1. The ventilation port 71 is provided with dustproof cotton 76 inside. The ventilation port 71 is sealed by a sealing plate 72. A baffle 73 is provided on the outside of the ventilation port 71, and the upper end of the baffle 73 has an opening. Two guide posts 74 are provided at the lower end of the sealing plate 72. The guide posts 74 are slidably connected to the bottom of the baffle 73. A connecting plate 75 is provided in the middle of the outer side of the baffle 73. The connecting plate 75 is fixedly connected to the lifting rod 62.

[0026] Among them, when the intake mechanism 2 is working normally, such as Figure 3-5 Air inside the cabinet 1 enters from the inside of the air inlet 21, and then enters the air inlet box 22 after being filtered by the dustproof mesh 23 and the dustproof cotton 24. The air inlet slot 25 at the upper end of the air inlet box 22 is closed. The air inside the air inlet box 22 enters the air inlet pipe 4 through the air inlet slot 25 at the lower end of the air inlet box 22. Then the air inlet pipe 4 delivers the gas to the dehumidification and cooling zone 33 for cooling and dehumidification, and then blows air into the cabinet 1 through the blower mechanism 3. When ventilation is required inside cabinet 1, such as Figure 6 The air intake box 22 is driven to rotate 180 degrees by the flipping mechanism 6, so that the inner side of the air intake port 21 is closed and the outer side of the air intake port 21 is opened. That is, the dustproof mesh plate 23 and the dustproof cotton 24 are located outside the air intake port 21. At this time, the external air of the cabinet 1 enters the air intake box 22 after being filtered by the dustproof mesh plate 23 and the dustproof cotton 24. After the air intake box 22 is flipped, the air intake slot 25 at the upper end is still closed. After the air intake box 22 draws in the external air of the cabinet 1, it enters the air intake pipe 4 through the air intake slot 25 at the lower end of the air intake box 22. Then, the blower mechanism 3 blows air into the cabinet 1. At the same time as the air intake box 22 is flipped, the ventilation port 71 is opened, and the air inside the cabinet 1 can be discharged through the ventilation port 71, thereby completing the ventilation work of the cabinet 1. The telescopic rod 61 extends and retracts, causing the two racks 63 and the lifting rod 62 to rise simultaneously. This causes the two racks 63 to drive the two gears 64 to rotate 180 degrees, allowing the two air intake boxes 22 to rotate 180 degrees and flip over. As a result, air can be drawn in from inside or outside the cabinet 1 as needed. Simultaneously, the lifting rod 62 rises, causing the sealing plate 72 to rise through the connecting plate 75, opening the ventilation port 71. Therefore, when ventilating the inside of the cabinet 1, the air inside the cabinet 1 can be discharged through the ventilation port 71.

[0027] The evaporator 51 has a water storage component 9 at its bottom. The water storage component 9 includes a drain plate 91 located at the bottom of the dehumidification and cooling zone 33. The drain plate 91 has baffles 92 around its upper perimeter. The drain plate 91 has a water collection area 93 at its bottom. The water collection area 93 has a level gauge 94 inside it. The bottom side of the water collection area 93 has a drain pipe 95. The drain pipe 95 is controlled to open or close by a drain valve 96. The refrigeration equipment 5 includes a condenser 52 located inside it. The back side of the condenser 52 has a water box 53. The water box 53 has a water inlet 54 at its upper end. The water inlet 54 is located at the upper end of the refrigeration equipment 5 shell. The outlet of the drain pipe 95 is located inside the water inlet 54.

[0028] In this process, moisture in the air turns into water droplets after passing through the evaporator 51 and is collected by the water storage component 9. The water droplets flow from the drain plate 91 at the bottom of the evaporator 51 into the water collection area 93. The water level changes can be detected by the level gauge 94 inside the water collection area 93. When the set value is reached, the drain valve 96 is opened, and the water inside the water collection area 93 flows out through the drain pipe 95 and into the water box 53 on the back side of the condenser 52 through the water inlet 54 at the top of the refrigeration equipment 5 housing. At this time, the water temperature is low, which can improve the heat dissipation effect of the condenser 52. Since the water exchanges heat with the condenser 52, the water temperature will rise, which will accelerate the vaporization of the water. Since the water inlet 54 is an open structure, the water will be discharged through the water inlet 54 after vaporization. The water vaporization will also take away heat, which can further improve the heat dissipation effect of the condenser 52.

[0029] Working principle and usage process of this invention: During normal dehumidification and heat dissipation operation, the air intake mechanism 2 draws in air from inside the cabinet 1. This air enters through the air inlet 21 and passes through two air intake pipes 4 into the dehumidification and cooling zone 33. The evaporator 51 inside the dehumidification and cooling zone 33 is cooled by the refrigeration equipment 5, maintaining a low temperature. As the air passes through the low-temperature evaporator 51, its temperature decreases, and the moisture in the air condenses into water droplets that adhere to the evaporator 51, further reducing the humidity. This results in low-temperature, low-humidity air. Two cross-flow fans 35... Simultaneous rotation allows low-temperature, low-humidity air to be drawn in by two cross-flow fans 35 through two air ducts 34 on one side of the dehumidification and cooling zone 33, and discharged into the cabinet 1 through the exhaust port 31. Air drawn in from inside the cabinet 1 is cooled and dehumidified before being discharged back into the cabinet 1, forming an internal dehumidification and cooling cycle. This prevents the loss of low-temperature, low-humidity air from inside the cabinet 1, saving energy. When ventilation is needed inside the cabinet 1, the inlet box 22 is rotated 180 degrees by the flipping mechanism 6, closing the inner side of the inlet 21 and opening the outer side of the inlet 21. When the air inlet 21 is open, the dust filter 23 and dustproof cotton 24 are located outside the air inlet 21. At this time, the outside air of the cabinet 1 is filtered by the dust filter 23 and dustproof cotton 24 and enters the air inlet box 22. The air inlet box 22 draws in the outside air of the cabinet 1 and enters the air inlet pipe 4 through the air inlet slot 25 at the lower end of the air inlet box 22. Then, the air blower mechanism 3 blows air into the cabinet 1. At the same time as the air inlet box 22 flips, the ventilation port 71 is opened, and the air inside the cabinet 1 can be discharged through the ventilation port 71, thereby completing the ventilation work of the cabinet 1. In addition, Moisture in the air turns into water droplets through the evaporator 51 and is collected by the water storage component 9. Then, it is discharged into the water box 53 on the back side of the condenser 52 through the drain pipe 95. At this time, the water temperature is low, which can improve the heat dissipation effect of the condenser 52. Since the water exchanges heat with the condenser 52, the water temperature will rise, thus accelerating the vaporization of the water. Since the water inlet 54 is an open structure, the water will be discharged through the water inlet 54 after vaporization. The water vaporization will also take away heat, which can further improve the heat dissipation effect of the condenser 52.
