Description

An electrical cabinet with ventilation and moisture-proof functions

[0001] The present invention relates to the technical field of moisture-proof and temperature-reducing technology for electrical cabinets, in particular to an electrical cabinet with ventilation and moisture-proof functions.

[0002] Electronic components within current electrical cabinets carry a significant workload, and cabinets are often installed outdoors, making them susceptible to the effects of the ambient temperature. When the temperature is excessively high or low, the temperature difference between the outside and the cabinet is large, which can easily generate moisture and cause water droplets to form inside the cabinet. This can lead to severe humidity inside the cabinet, shortening the lifespan of the electronic components and creating safety hazards during operation. The components within the cabinet generate significant heat energy, and if this heat is not dissipated promptly, the high temperatures can cause unstable operation of the components, accelerate component aging, shorten their lifespan, and even cause them to malfunction.

[0003] After searching, the Chinese patent publication number CN218005583U discloses a moisture-proof heat dissipation electrical cabinet, including a cabinet body, a moisture-proof filter and a liquid cooling heat exchange system. A plurality of electrical components are arranged in the cabinet body, and ventilation holes are provided on the cabinet body. The moisture-proof filter is provided corresponding to the ventilation holes. The liquid cooling heat exchange system includes a liquid cooling circulation loop, a liquid pump and a heat absorption part. There is a liquid cooling medium in the liquid cooling circulation loop, and the heat absorption part is provided on the liquid cooling circulation loop and in the cabinet body. The liquid pump is used to provide power for the flow of the liquid cooling medium in the liquid cooling circulation loop. In the technical solution of this utility model, the ventilation holes provided on the cabinet body are used to assist in heat dissipation, and the moisture-proof filter provided on the ventilation holes absorbs the water vapor in the cabinet body and the water vapor contained in the air entering the cabinet body, thereby achieving a moisture-proof effect; under the action of the liquid pump, the liquid cooling medium in the liquid cooling heat exchange system absorbs the heat radiated by the electrical components when flowing into the heat absorption part, and takes the heat out of the cabinet body when flowing out of the heat absorption part, thereby achieving a heat dissipation effect;

[0004] The above patent has the following defects: 1. Although the moisture-proof filter can absorb the water vapor in the gas when the gas outside the cabinet flows into the cabinet, the water vapor inside the electrical cabinet will only be adsorbed when the air containing water vapor comes into contact with the filter. When there is no fan driving the air flow in the cabinet, the moisture-proof effect inside the cabinet is poor; 2. The cabinet uses liquid cooling to cool the heat inside the cabinet. The liquid cooling medium can only passively absorb heat energy, which is different from the fan actively blowing the cabinet to dissipate heat, resulting in poor heat dissipation effect of the cabinet. In view of this, we propose an electrical cabinet with ventilation and moisture-proof functions.

[0015] As can be seen from the above technical solutions, the electrical cabinet with ventilation and moisture-proof functions provided in the embodiments of this specification has at least the following beneficial effects:

[0016] (1) The present invention uses a corrugated moisture-proof plate to perform large-area dehumidification and moisture-proofing on the interior of the electrical cabinet, and a coolant cooling device to perform liquid cooling on the components. The cooling of the coolant during the circulation period is utilized to improve the continuous cooling effect of the coolant. Combined with the air-cooling cooling device, the effect of rotating air cooling of the components inside the electrical cabinet is achieved. At the same time, the wind force is utilized to make the dehumidifier particles fully contact and react with the air, further increasing the saturation of the dehumidifier particles to water vapor adsorption and improving the dehumidification effect.

[0017] (2) The present invention delivers cooling to the cooling box through a semiconductor refrigerator. Cold air flows from the connecting socket to the sealing plug by air pressure. The cold air flows from the connecting cavity to the connecting seat through the sealing plug and is sprayed out from the nozzle in the nozzle at the installation mesh plate to achieve the effect of air cooling. During the period when the arm drives the installation mesh plate to move, the active push rod contacts and squeezes the pressed plate. The pressed plate is driven by force to drive the nozzle to deflect the angle in the connecting seat, thereby achieving the effect of rotating cold air blowing by the nozzle, increasing the air cooling range, and then improving the effect of cold air cooling a large area of ​​components on the installation mesh plate, further improving the air cooling rate.

[0018] (3) The present invention drives the mounting screen on the arm to move by driving the crankshaft on the active motor, and the mounting screen drives the components installed thereon to move and cool. The mounting screen drives the hydraulic plate through the feed pipe to squeeze the coolant in the transfer bin, and the coolant is squeezed into the mounting screen through the feed pipe to achieve the effect of replacing the hot liquid with the cold liquid. The hot liquid is driven by the alternating hot and cold to be discharged from the discharge pipe to the cooling pipe through the telescopic rod, and the semiconductor refrigerator cools the hot liquid in the cooling pipe. The cooled coolant flows back to the transfer bin through the one-way transfer pipe, thereby forming a circulation state. The coolant is cooled during the circulation process, and then the cooling effect of the mounting screen is achieved by the continuous and cyclic cooling of the coolant, thereby improving the overall liquid cooling rate and realizing the secondary use of the cold air of the semiconductor refrigerator.

[0019] (4) The present invention uses a dehumidifier supply device to utilize a reciprocating active push rod to drive the pressure roller seat to contact and squeeze the corrugated moisture-proof plate while moving. The corrugated moisture-proof plate moves downward after being subjected to force. When the active push rod resets and moves, the corrugated moisture-proof plate gradually loses the squeeze of the pressure roller seat. The corrugated moisture-proof plate resets upward according to the elastic force of the spring connected to the fixed plate. During the up and down period, a vibration force is generated. The vibration force can shake the dehumidifier particles inside the corrugated moisture-proof plate, and then the dehumidifier particles fully contact and react with the air, further improving the saturation of the dehumidifier particles to water vapor adsorption, and improving the dehumidification effect. By starting the control valve to open, the dehumidifier particles will be discharged from the telescopic tube by gravity and the shaking force to collect the inside of the base. At the same time, new dehumidifier particles are discharged from the top telescopic tube into the corrugated moisture-proof plate by the squeezing force of the pressure plate, so that the corrugated moisture-proof plate can continue to dehumidify through the dehumidifier particles, thereby improving the overall dehumidification working time of the corrugated moisture-proof plate.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Refer to Figure 11, which shows an electrical cabinet with ventilation and moisture-proof functions. The cabinet comprises a cabinet body 1, to which a cabinet door 2 is hingedly connected; an air-cooling device 3, mounted on the cabinet door 2, for cooling components within the cabinet body 1; a coolant cooling device 4, mounted on the cabinet body 1, for cooling components within the cabinet body 1; a dehumidifier supply device 5, mounted on the cabinet body 1, and provided with a corrugated moisture-proof plate 6; and a ventilation sash 7, fixedly mounted on one side of the cabinet body 1, with a moisture-proof filter fixedly mounted on the bottom thereof. The ventilation sash 7 is used to ensure ventilation within the electrical cabinet. The tilted design with the vents facing downward effectively reduces moisture infiltration, thereby achieving the desired effect of both ventilation and moisture-proofing the cabinet body 1. A protective top cover 8 is fixedly mounted on the top of the cabinet body 1, and legs 9 are fixedly mounted on the bottom thereof.

[0035] In this embodiment, the coolant cooling device 4 includes a mounting box 41, the surface of which is fixedly connected to one side of the cabinet 1. An active motor 42 is installed inside the mounting box 41. The output shaft of the active motor 42 is connected to a drive crankshaft 43. The end of the drive crankshaft 43 is slidably connected to an arm 44. A mounting mesh 45 is fixedly connected to the surface of the arm 44. A circulating cooling device 46 is provided on the mounting mesh 45. The surface of the drive crankshaft 43 is rotatably connected to the interior of the cabinet 1. The mounting mesh 45 has mounting holes for mounting components. A cooling liquid cavity is defined within the mounting mesh 45. Coolant is filled in the cooling liquid cavity of the mounting mesh 45. By providing the mounting mesh 45 filled with coolant, the components thereon are liquid-cooled and cooled. The active motor 42 drives the mounting mesh 45 on the arm 44 to move by driving the crankshaft 43. The mounting mesh 45 drives the components mounted thereon to move and be air-cooled, further promoting cooling of the components.

[0036] Furthermore, the circulating cooling device 46 includes a telescopic rod 461 and a cooling box 468. One end of the telescopic rod 461 is fixedly connected to the bottom of the mounting mesh plate 45, and the other end of the telescopic rod 461 is fixedly connected to the discharge pipe 462. The top of the discharge pipe 462 is fixedly connected to the cooling pipe 463. The end of the cooling pipe 463 away from the discharge pipe 462 is fixedly connected to the one-way transfer pipe 464. The end of the one-way transfer pipe 464 is fixedly connected to the transfer bin 465. The interior of the transfer bin 465 is slidingly connected to a hydraulic plate 466. One side of the hydraulic plate 466 is fixedly connected to a feed pipe 467. The top of the cooling box 468 is fixedly connected to a semiconductor refrigerator 469. The active motor 42 drives the crankshaft 43 to move the mounting mesh plate 45 on the arm 44, and the mounting mesh plate 45 drives the components installed thereon to move and cool. The mounting mesh plate 45 drives the hydraulic plate 466 through the feed pipe 467 to squeeze the coolant in the transfer bin 465. The coolant is squeezed into the mounting mesh plate 45 through the feed pipe 467 to achieve the effect of replacing the hot liquid with the cold night. The hot liquid is driven by the alternating hot and cold to be discharged from the discharge pipe 462 to the cooling pipe 463 through the telescopic rod 461. The semiconductor refrigerator 469 cools the hot liquid in the cooling pipe 463, and the cooled coolant flows back to the transfer bin 465 through the one-way transfer pipe 464, thereby forming a circulation state. The coolant is cooled during the circulation process, thereby achieving the effect of continuous and cyclic liquid cooling of the mounting mesh plate 45, thereby improving the overall liquid cooling rate and realizing the secondary utilization of the cold air of the semiconductor refrigerator 469.

[0037] Furthermore, the top of the discharge pipe 462 and the surface of the one-way transfer pipe 464 are fixedly connected to the bottom of the cooling box 468, the cooling pipe 463 is located inside the cooling box 468, the bottom end of the feed pipe 467 is fixedly connected to the top of the mounting mesh plate 45, and the bottom of the cooling box 468 is fixedly connected to the top of the cabinet 1.

[0038] It is worth noting that the interior of the transfer bin 465 is slidably connected to a pressure-compensating plate 4651, the interior of the pressure-compensating plate 4651 is slidably connected to the surface of the one-way transfer tube 464, and the side of the pressure-compensating plate 4651 close to the one-way transfer tube 464 is elastically connected to the inner wall of the transfer bin 465 through a spring sheet. The pressure-compensating plate 4651 can generate an elastic force through the spring sheet, and the elastic force always squeezes the coolant flowing out of the one-way transfer tube 464, causing the coolant to have a force squeezing toward the end of the feed tube 467, thereby achieving the effect of pressure compensation for the coolant in the transfer bin 465.

[0039] It is worth noting that both sides of the mounting mesh plate 45 are fixedly connected with active push rods 34, and the surface of the active push rods 34 is slidably connected to the interior of the cabinet body 1. The cabinet body 1 limits the movement of the active push rods 34 through a slider so that it can only move in a straight line. Therefore, the arm 44 fixedly connected to the active push rods 34 and the mounting mesh plate 45 as a whole can only move in a straight line. The air-cooling cooling device 3 includes a connecting seat 31, the surface of the connecting seat 31 is fixedly connected to the surface of the cabinet door 2, and the interior of the connecting seat 31 is elastically connected to the nozzle 32 through a torsion spring, and the surface of the nozzle 32 is fixedly connected to the pressed plate 33. When the active push rod 34 moves and resets, the pressed plate 33 gradually loses the squeezing force of the active push rod 34. At this time, the nozzle 32 is elastically reset by the torsion spring at the end, thereby achieving the effect of reciprocating rotation of the nozzle 32, and realizing the effect of the nozzle 32 switching the positive and negative angles and rotating and blowing.

[0040] In addition, the air-cooling cooling device 3 also includes a sealing plug 35, one end of the sealing plug 35 is fixedly connected to the top of the inner wall of the cabinet door 2, and the other end of the sealing plug 35 is plugged with a connecting socket 36, and the top of the connecting socket 36 is fixedly connected to the bottom of the cooling box 468. The sealing plug 35 and the connecting socket 36 are used to connect the cabinet door 2 and the cooling box 468. When the cabinet door 2 is opened, the sealing plug 35 can be detached from the connecting socket 36.

[0041] In addition, the dehumidifier supply device 5 includes a storage box 51 and a collection base 54. The bottom of the storage box 51 is fixedly connected to the top of the cabinet 1. A pressure rod 52 is elastically connected to one side of the storage box 51 through a spring. The end of the pressure rod 52 is fixedly connected to a pressure plate 53. The bottom of the storage box 51 is fixedly connected to the top of the corrugated moisture-proof plate 6 through a telescopic tube. The bottom of the collection base 54 is fixedly connected to the inside of the cabinet 1. The top of the collection base 54 is fixedly connected to a control valve 55. The top of the control valve 55 is fixedly connected to the bottom of the corrugated moisture-proof plate 6 through a telescopic tube. By starting the control valve 55 to open, the dehumidifier particles will be discharged from the telescopic tube to the inside of the collection base 54 by gravity and shaking force. At the same time, new dehumidifier particles are discharged from the top telescopic tube into the corrugated moisture-proof plate 6 by the squeezing force of the pressure plate 53, so that the corrugated moisture-proof plate 6 can continue to dehumidify through the dehumidifier particles, thereby improving the overall dehumidification working time of the corrugated moisture-proof plate 6.

[0042] It is further explained that the surface of the active push rod 34 is fixedly connected to the pressure roller seat 56, and the surface of the corrugated moisture-proof plate 6 is elastically connected to the fixed plate 57 through a spring. The surface of the fixed plate 57 is fixedly connected to the inner wall of the cabinet 1, and the corrugated moisture-proof plate 6 is slidably connected to the fixed plate 57 through a slide rod. During the reciprocating movement, the active push rod 34 drives the pressure roller seat 56 to contact and squeeze the corrugated moisture-proof plate 6 while moving. The corrugated moisture-proof plate 6 moves downward after being forced. When the active push rod 34 resets and moves, the corrugated moisture-proof plate 6 gradually loses the squeezing of the pressure roller seat 56. The corrugated moisture-proof plate 6 resets upward according to the spring force connected to the fixed plate 57, generating a vibration force during the up and down period. The vibration force can shake the dehumidifier particles inside the corrugated moisture-proof plate 6, thereby allowing the dehumidifier particles to fully contact and react with the air, further improving the saturation of the dehumidifier particles to adsorb water vapor and improving the dehumidification effect.

[0043] When the electrical cabinet with ventilation and moisture-proof functions of the present invention is in use, the components are pre-installed on the mounting mesh plate 45, and the mounting mesh plate 45 is provided with mounting holes for component installation, and a cooling liquid cavity is provided therein. The cooling liquid enters the cooling liquid cavity of the mounting mesh plate 45 through the feed pipe 467 and is discharged from the discharge pipe 462 through the telescopic rod 461. Under normal circumstances, the cooling liquid is in a static state in the cooling liquid cavity, and the cooling liquid can liquid-cool the components on the mounting mesh plate 45. When the heat energy inside the cabinet 1 accumulates too much, by starting the semiconductor refrigerator 469 and the active motor 42, the semiconductor refrigerator 469 transmits the cooling to the cooling box 468 through its own fan, and the cold air uses the air pressure to flow from the connecting socket 36 to the sealing plug 35. A connecting cavity is provided inside the cabinet door 2 for connecting the sealing plug 35 with the connecting seat 31. The cold air flows from the connecting cavity to the connecting seat 31 through the sealing plug 35, and the connecting The receiving seat 31 and the rotating end of the nozzle 32 are in a connected state, and the cold air is evenly sprayed from the nozzle in the nozzle 32 toward the mounting mesh plate 45, achieving the effect of air cooling and cooling. The air cooling combined with liquid cooling improves the heat dissipation rate of the entire components on the mounting mesh plate 45; at the same time, when the active motor 42 is in operation, its output shaft rotates by driving the crankshaft 43. Since the active push rod 34 is slidably connected to the interior of the cabinet 1, the cabinet 1 limits the movement of the active push rod 34 through the slider, so that it can only move in a straight line. Therefore, the arm 44 fixedly connected to the active push rod 34 and the mounting mesh plate 45 can only move in a straight line as a whole, that is, when the driving crankshaft 43 rotates, the arm 44 drives the mounting mesh plate 45 to move back and forth in a straight line. During the movement, the mounting mesh plate 45 drives the components installed thereon to move synchronously, thereby increasing the contact amount between the components and the gas inside the cabinet 1 during the movement, and then using the airflow generated when the components move to assist in cooling;In addition, during the movement of the mounting mesh plate 45, the feed pipe 467 on it drives the hydraulic plate 466 to move and squeeze toward the one-way transfer pipe 464, and the squeezing force drives the coolant inside the transfer bin 465 to be replenished into the feed pipe 467. The squeezing force of the hydraulic plate 466 in the transfer bin 465 drives the replenished coolant to be squeezed into the mounting mesh plate 45 at high pressure. After being pressurized, the original coolant in the mounting mesh plate 45 is discharged from the discharge pipe 462 to the cooling pipe 463 through the telescopic rod 461. When the original coolant passes through the cooling pipe 463, it is cooled by the cold air output by the semiconductor refrigerator 469. After cooling, it continues to flow to the one-way transfer pipe 464 using hydraulic pressure, and then flows out of the one-way transfer pipe 464. The coolant flows into the transfer bin 465 through the transfer pipe 464, and the cooled coolant is located between the pressure compensation plate 4651 and the hydraulic plate 466. After being squeezed by the hydraulic plate 466 next time, the cooled coolant will flow into the installation mesh plate 45 through the feed pipe 467 again, thereby forming a circulation state. During the period of controlling the reciprocating movement of the installation mesh plate 45, the force of movement is used to drive the coolant to circulate, and the coolant is cooled during the circulation process, thereby achieving the effect of continuous and cyclic liquid cooling of the installation mesh plate 45, thereby improving the overall liquid cooling rate and realizing the secondary utilization of the cold air of the semiconductor refrigerator 469. Furthermore, while the arm 44 drives the mounting mesh 45 to move, the active push rod 34 moves accordingly. During this movement, the active push rod 34 contacts and compresses the pressed plate 33. The pressed plate 33 is subjected to the force, which drives the nozzle 32 to angularly deflect within the connecting seat 31, thereby achieving the effect of rotating the cooling air from the nozzle 32, increasing the cooling range and the cooling effect of the cooling air on the components on the mounting mesh 45 over a large area, further increasing the cooling rate. When the active push rod 34 moves and resets, the pressed plate 33 gradually loses the squeezing force of the active push rod 34. At this time, the nozzle 32 is elastically reset by the torsion spring at the end, thereby achieving the effect of reciprocating rotation of the nozzle 32, and realizing the effect of the nozzle 32 switching between positive and negative angles and rotating the blowing air.

[0044] Under normal circumstances, the interior of the corrugated moisture-proof plate 6 is filled with dehumidifier particles, and the corrugated moisture-proof plate 6 is in a mesh state as a whole. The dehumidifier particles achieve the effect of water vapor adsorption through the mesh holes in the corrugated moisture-proof plate 6. The control valve 55 is in a closed state, and the dehumidifier particles in the collecting base 54 are always squeezed by the elastic force of the pressure plate 53, and there is a force moving toward the telescopic tube. When the interior of the cabinet 1 is in an air-cooling state, the cold air ejected from each nozzle 32 blows the air flow inside the cabinet 1. The circulating air flow can increase the contact rate with the dehumidifier particles, thereby improving the dehumidification efficiency of the dehumidifier particles on the air inside the cabinet 1. At the same time, the active push rod 34 during the reciprocating movement drives the pressure roller seat 56 to contact and squeeze the corrugated moisture-proof plate 6 while moving. The corrugated moisture-proof plate 6 moves downward after being forced. When the active push rod 34 resets and moves, the corrugated moisture-proof plate 6 gradually loses the squeezing of the pressure roller seat 56. The corrugated moisture-proof plate 6 resets upward according to the spring force connected to the fixed plate 57, and generates a vibration force during the up and down period. The vibration force can shake the dehumidifier particles inside the corrugated moisture-proof plate 6, thereby making the dehumidifier particles fully contact and react with the air, further improving the saturation of the dehumidifier particles to water vapor adsorption, and improving the dehumidification effect. When the dehumidifier particles in the corrugated moisture-proof board 6 are oversaturated, the control valve 55 is opened by starting, and the dehumidifier particles are discharged from the telescopic tube to the inside of the collection base 54 by gravity and shaking force. At the same time, new dehumidifier particles are discharged from the top telescopic tube into the corrugated moisture-proof board 6 by the squeezing force of the pressure plate 53, so that the corrugated moisture-proof board 6 can continue to perform dehumidification work through the dehumidifier particles, thereby improving the overall dehumidification working time of the corrugated moisture-proof board 6.
