Description

Technical Field

[0001] The 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 getting higher and higher. For example, PLC control cabinets, frequency conversion cabinets, etc., there are more and more precision components and power devices used in power cabinets. The more precision components, the higher the requirements for the use environment, such as temperature, humidity, dust and other environmental requirements, especially the temperature requirements. The high-power devices in the power cabinet will release a lot of heat when working, and this heat must be guaranteed to be dissipated in time. If the heat dissipation is not good, it will damage the service life and safety of the power devices. The current power cabinet uses fan cooling to collectively dissipate the heat and cool down all the 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, and 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). The 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, and can realize the circulation process of cooling water in the internal cavity of the first arc plate through the submersible pump, effectively produce a cooling effect on the air circulating in the ventilation pipe, so that the air blown to the electrical component through the ventilation pipe is cooled, further improving the heat dissipation effect of the electrical component, and can realize the slow rotation of each cylinder at the same time through the motor, so that each part of the electrical component can be blown in all directions, further improving the heat dissipation effect of the electrical component, and because it has the function of blowing air around the electrical component in all directions, it can effectively reduce the amount of dust adsorbed on the electrical component. This patented technology solves the problem that the internal heat dissipation of the power cabinet is uneven, which will affect the normal operation of the electrical components over time, and in the process of heat dissipation through wind, even if there is a dust filter, the dust mixed in the outside air will more or less enter the power cabinet, and most of these dusts are 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 power devices inside the power cabinet varies when working, it is necessary to solve the problem of efficiently dissipating heat for the hotter power devices in the prior art.

[0105] According to the above embodiments, 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 fixedly assembled using external bolts;

[0107] The circuit lines of the power equipment can be arranged vertically in the wiring holes 313 in the top plate frame 306 on the top of the power cabinet 2, and the lines are arranged and discharged through the line wiring 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, the air from the ventilation rotating frame 301 connected to the bottom of the ventilation vertical channel 305 can be sucked in and compressed, and blown into the inside of the power cabinet 2 for heat dissipation;

[0111] The semiconductor refrigerator 3105 in the cooling structure 31 cools the coolant in the cooling box 3103. The coolant is cooled by starting the circulation pump 3102. The circulation pump 3102 extracts the coolant from the cold water tank inside the cooling box 3103 and discharges it into the circulation coil 3101. The coolant circulates in the ventilation shaft 305 through the circulation coil 3101, and the air extracted by the heat dissipation fan 308 is cooled by heat conduction.

[0112] Then, the coolant is 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, so that 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 extracted by the circulation pump 3102, which is beneficial for the coolant to increase the degree of cooling through the semiconductor refrigerator 3105;

[0113] One end of the heat dissipation fin of the semiconductor refrigerator 3105 can be passed through the start-up heat dissipation fan 3107, and the heat dissipation fan 3107 provides wind to blow toward the heat dissipation fin of the semiconductor refrigerator 3105, which can be cooled by air, and the wind pressure blown into the heat dissipation fin can be discharged to the outside through the slots on both sides of the ventilation frame 3106;

[0114] The cooling fan 308 can be rotated in a ring 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] The servo motor 304 is started. After the servo motor 304 is started, the spur gear 303 is driven to rotate, so that the spur gear 303 is meshed 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 assembled on the cabinet base 1 can be rotated around the power equipment;

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

[0117] When targeted and efficient heat dissipation is performed on the power 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 power equipment. The servo motor 2 312 is started to drive the reciprocating screw 310 to rotate. The reciprocating screw block 311 is spirally driven by the rotating reciprocating screw 310, so that the reciprocating screw block 311 moves back and forth up and down along the reciprocating screw 310 inside the vertical groove 309. The infrared temperature sensor 314 inside the reciprocating screw block 311 can be used to detect the temperature of the power equipment on the power equipment assembly plate 13 with different heights. When it is detected that only a single power 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 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 started according to the direction and position of the high temperature equipment, so that the distance between the electric telescopic rods 3206 and the universal ball seat 1 3205 and the universal ball seat 2 3207 is adjusted, so that the direction of the wind cone outlet of the wind conical bucket 3203 is adjusted, and the sealed flexible tube 3202 can be rotated at any angle when the direction of the wind conical bucket 3203 is adjusted;

[0120] When the wind force of the positioning heat dissipation structure 3 is drawn in, the moisture in the outside air can be adsorbed and dehumidified by the circulating desiccant net 406 of the drying and ventilation structure 4;

[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 3 405 is started. After the servo motor 3 405 is started, the helical gear 404 is driven to rotate, so that the helical gear 404 is meshed with the helical gear ring 403, and the inner rail cylinder 402 fixedly installed at the bottom of the drying ring frame 401 is driven through the helical gear ring 403;

[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, and 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 blows it along the resistance heater 411 to the circulating desiccant net 406 on one side of the evaporation inner frame 408, so as to evaporate the moisture in the circulating desiccant at high temperature, so that the moisture evaporates from the circulating desiccant net 406 to the outside of the drying ring frame 401, and the circulating desiccant net 406 can be recycled;

[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 detachable cover plate 503. The wires pass between two flexible rubbers 505 to provide waterproof sealing for the discharged wires.
