Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation devices of power cabinets, and in particular to a high-efficiency heat dissipation power cabinet for electric power engineering. Background Art

[0002] With the continuous development of intelligent power distribution, the requirements for power cabinets are becoming increasingly higher. For example, PLC control cabinets, frequency conversion cabinets, etc., the number of precision components and electrical devices used in power cabinets is also increasing. The more precision components, the higher the requirements for the operating environment, such as temperature, humidity, dust and other environmental requirements, especially the temperature requirement. The high-power devices in the power cabinet will release a large amount of heat when working, and this heat must be dissipated in a timely manner. If the heat dissipation is not good, the service life and safety of the power devices will be damaged. Current power cabinets use fan cooling to collectively dissipate heat and cool all electrical components in the power cabinet. However, due to the limited number of fans, only the electrical components close to the fan side have a good heat dissipation effect, while the electrical components far away from the fan have a poor heat dissipation effect. A Chinese patent discloses a high-efficiency heat dissipation power cabinet for power engineering (authorization announcement number CN113517639B). This patent technology discloses a high-efficiency heat dissipation power cabinet for power engineering, including a base, and legs are fixed at the four corners of the bottom surface of the base. The present invention can achieve the purpose of directly dissipating heat for each electrical component one-to-one by installing each electrical component in a separate cylinder. Moreover, the submersible pump can realize the circulation process of cooling water in the internal cavity of the first curved plate, effectively producing a cooling effect on the air circulating in the ventilation pipe, so that the air blown to the electrical components through the ventilation pipe is cooled, further improving the heat dissipation effect of the electrical components. Moreover, the motor can simultaneously realize the slow rotation of each cylinder, so that every part of the electrical component can be blown in all directions, further improving the heat dissipation effect of the electrical components. Moreover, due to the function of blowing air around the electrical components in all directions, the amount of dust adsorbed on the electrical components can be effectively reduced. This patented technology solves the problem of uneven heat dissipation inside the power cabinet, which will affect the normal operation of the electrical components over time. Moreover, during the heat dissipation process, even if there is a dust filter, dust mixed in the outside air will more or less enter the power cabinet. Most of this dust is adsorbed on the electrical components, causing the electrical components to heat up more, seriously affecting the normal operation of the electrical components.

[0003] However, in the prior art, since the heat emitted by multiple electrical devices inside the power cabinet varies during operation, there is a need to solve the problem of efficiently dissipating heat for the hotter electrical devices in the prior art.

The disassembly cover 503 can be detachably mounted on the outside of the cable management side frame 502 via the mounting bolts.

[0105] According to the above embodiment, the working principle of the present invention is:

[0106] The power equipment installed in the power cabinet is placed on the power equipment assembly plate 13, and the power equipment is locked and fixed using external bolts;

[0107] The circuit lines of the power equipment can be arranged vertically in the wire management holes 313 in the top plate frame 306 on the top of the power cabinet 2, and the lines are arranged and connected through the wire management structure 5;

[0108] The power equipment installed inside the power cabinet 2 can be cooled normally and cooled by wind direction positioning through the positioning heat dissipation structure 3;

[0109] During normal heat dissipation, the cooling structure 31 cooperates with the heat dissipation fan 308 to cool the internal space of the power cabinet 2;

[0110] When the cooling fan 308 is started, it can suck in and compress the air from the ventilation rack 301 connected to the bottom of the ventilation vertical channel 305, and blow it into the interior of the power cabinet 2 for heat dissipation;

[0111] The semiconductor refrigerator 3105 in the cooling structure 31 cools the coolant inside the cooling box 3103. The cooled coolant is then pumped through the circulating pump 3102, which draws the coolant from the cold water tank inside the cooling box 3103 and discharges it into the circulating coil 3101. The coolant then circulates through the circulating coil 3101 within the ventilation shaft 305, cooling the air drawn in by the cooling fan 308 through heat conduction.

[0112] The coolant is then discharged into the circulation tank of the cooling box 3103 through the circulation coil 3101, so that the coolant discharged into the circulation tank continues to rise to the overflow plate 3104, and the coolant slowly overflows into the cold water tank through the overflow plate 3104. This process can increase the interval time for the coolant to be pumped by the circulation pump 3102, which is conducive to the coolant passing through the semiconductor refrigerator 3105 to increase the degree of temperature reduction;

[0113] One end of the heat dissipation fin of the semiconductor cooler 3105 can be passed through the start-up heat dissipation fan 3107, which provides wind to blow toward the heat dissipation fin of the semiconductor cooler 3105, thereby cooling it. The wind pressure blown into the heat dissipation fin can be discharged to the outside through the grooves on both sides of the ventilation frame 3106;

[0114] The cooling fan 308 can rotate in a circular shape around the power equipment installed on the power equipment assembly plate 13 on the cabinet base 1 through the ventilation rotating frame 301;

[0115] Start the servo motor 304. After the servo motor 304 is started, it drives the spur gear 303 to rotate, so that the spur gear 303 engages with the inner gear ring 302. The rotating inner gear ring 302 drives the ventilation rotating frame 301 to rotate inside the cabinet base 1, so that the ventilation vertical channel 305 installed on the cabinet base 1 can be rotated around the power equipment.

[0116] Provides efficient heat dissipation for power equipment in a ring-shaped manner;

[0117] When performing targeted and efficient heat dissipation on electrical equipment of different specifications arranged inside the power cabinet 2, first, the servo motor 2 312 is started in the ventilation vertical channel 305 that rotates in a ring around the electrical equipment. The servo motor 2 312 starts to drive the reciprocating screw 310 to rotate. The rotating reciprocating screw 310 transmits a spiral transmission to the reciprocating screw block 311, so that the reciprocating screw block 311 moves back and forth along the reciprocating screw 310 inside the vertical slot 309. The infrared temperature sensor 314 inside the reciprocating screw block 311 can detect the temperature of the electrical equipment on the electrical equipment assembly plate 13 at different heights. When it is detected that only a single electrical equipment has a high temperature;

[0118] The ventilation vertical channel 305 stops at the position corresponding to the high-temperature power equipment, and at the same time, the wind direction adjustment structure 32 guides the wind force of the heat dissipation fan 308 to blow on the high-temperature equipment, thereby providing a targeted cooling treatment for the equipment.

[0119] When the wind direction adjustment structure 32 is used for wind direction adjustment, the four electric telescopic rods 3206 are activated in coordination with the direction and position of the high-temperature equipment to adjust the distance between the electric telescopic rods 3206 and the universal ball seat 1 3205 and the universal ball seat 2 3207, so that the direction of the wind cone outlet of the wind conical bucket 3203 is adjusted. The sealed flexible tube 3202 can rotate at any angle when the direction of the wind conical bucket 3203 is adjusted;

[0120] When the wind from the positioning heat dissipation structure 3 is drawn in, it passes through the circulating desiccant net 406 of the drying and ventilation structure 4 and can absorb and dehumidify the moisture in the outside air;

[0121] The circulating desiccant net 406 contains a recyclable desiccant. When the recyclable desiccant in the circulating desiccant net 406 is heated and dried to discharge water vapor to the outside of the drying ring frame 401, the servo motor 405 is started. After the servo motor 405 is started, the helical gear 404 is driven to rotate, so that the helical gear 404 meshes with the helical gear ring 403, and the helical gear ring 403 drives the inner rail cylinder 402 fixedly installed at the bottom of the drying ring frame 401.

[0122] The drying ring frame 401 can be moved along the evaporation inner frame 408, and the drying fan 410 and the resistance heater 411 inside the evaporation inner frame 408 are started. The resistance heater 411 increases the temperature inside the evaporation inner frame 408. At the same time, the drying fan 410 is started to compress the air inside the fixed air guide frame 407 and blow it along the resistance heater 411 to the circulating desiccant net 406 on one side of the evaporation inner frame 408, thereby evaporating the moisture in the circulating desiccant at high temperature. The moisture evaporates from the circulating desiccant net 406 to the outside of the drying ring frame 401, and can be recycled by the circulating desiccant net 406.

[0123] The wires in the wire management cylinder 501 of the line management structure 5 are arranged inside the wire management side frame 502 and can be discharged through the wire management groove 504 of the removable cover 503. The wires pass between two flexible rubbers 505 to provide waterproof sealing for the discharged wires.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative work should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention are implemented in accordance with conventional means in the field unless otherwise specified or limited.
