Description
Technical Field
The utility model relates to an aeration fan converter cabinet air cooling system technical field especially indicates an aeration fan converter heat dissipation cooling cabinet.
Background
The sewage aeration fan is a key device in sewage treatment, and is mainly characterized in that a pipeline is connected to the bottom of a sewage treatment tank at the outlet of the fan for aeration, so that bioactive substances in the sewage treatment tank can be fully contacted with substances in sewage, and if the aeration fan is stopped due to faults, serious environmental protection accidents can be directly caused.
The stable long-term operation of the sewage aeration fan is contradictory with the characteristic that the frequency converter is easy to generate heat, and when the frequency converter works, because the current flowing through the frequency converter is very large, the heat generated by the frequency converter is very high, and the environmental temperature rise can be rapidly improved in a short time. The precision characteristic of the frequency converter enables the fault rate to exponentially rise along with the rise of the temperature and the service life to exponentially fall along with the rise of the temperature.
Especially in summer, the temperature in the converter cabinet of sewage aeration fan lasts on the high side, and the temperature can reach fifty degrees centigrade in the control cabinet, and too high temperature arouses the converter trouble easily to make its stop work, has great potential safety hazard. On the other hand, the frequency converter is expensive, the service life of the frequency converter can be shortened when the frequency converter is in a high-temperature environment for a long time, and great economic loss can be caused once the frequency converter is damaged.
The frequency converter cabinet of the existing sewage aeration fan adopts a closed cabinet type structure, a section bar framework is adopted, four sides are wrapped by iron plates, and the surfaces are coated with plastic spraying. Because the whole is a closed structure and only the electric cooling fan is arranged above the closed space, the heat generated in the closed space is larger than the cooling capacity, which is a direct reason for generating temperature rise. The self-contained heat-dissipation air outlet of the frequency converter of the aeration fan directly faces the cabinet top to exhaust air, hot air cannot be discharged completely in time under the condition, the hot air sinks to the bottom of the cabinet in a circulating mode to form a temperature rising source, and a small heat-dissipation fan on the cabinet top even can play a role in reaction under the condition that the wind direction is incorrect. If the roof of converter cabinet is got, can lead to the condition emergence in foreign matter and the toy got into the cabinet again, cause very big potential safety hazard.
SUMMERY OF THE UTILITY MODEL
Not enough to among the above-mentioned background art, the utility model provides an aeration fan converter heat dissipation cooling cabinet has solved the poor technical problem of current converter cabinet heat dispersion.
The technical scheme of the utility model is realized like this: a heat dissipation and cooling cabinet for an aeration fan frequency converter comprises a cylindrical cabinet body, wherein the aeration fan frequency converter is fixedly arranged at the bottom in the cabinet body, a heat dissipation fan is arranged at the top, and hot air generated by the aeration fan frequency converter is discharged from bottom to top through the heat dissipation fan. The top of the cabinet body is provided with the stand, and the stand sets up along the periphery wall interval of the cabinet body, and the passageway between the adjacent stand constitutes big louvre, the heat that the aeration fan converter of being convenient for produced discharges fast. The top of stand is connected with the roof that covers the cabinet body, and the roof can effectively be dustproof, waterproof, guarantees the safety in utilization when guaranteeing effective radiating. All be provided with the gauze between the adjacent stand and radiator fan's outer port department, the gauze can further prevent dust and prevent that the foreign matter from getting into the inside of the cabinet body, fully guarantees the security of equipment work.
Furthermore, the cooling fan is arranged on the top plate and vertically corresponds to the cooling air outlet of the frequency converter of the aeration fan, and the cooling fan vertically corresponds to the cooling air outlet of the frequency converter of the aeration fan, so that a good flow guiding effect can be achieved. The heat radiation fan absorbs heat and exhausts air, the hot air promotes the rotation of the heat radiation fan, and under the synergistic effect of the self-lifting of the hot air and the heat radiation fan, the high-temperature air in the cabinet body can be quickly discharged without circularly sinking to the bottom of the cabinet body.
Further, the stand sets up on the rolling disc, and the rolling disc below is provided with the connecting cylinder with the cabinet body intercommunication, is provided with the spout on the rolling disc, the spout and the periphery wall sliding fit of connecting cylinder. Through the rotation of rolling disc, can drive stand and roof synchronous rotation, and then can conveniently adjust radiator fan and aeration fan converter heat dissipation air outlet's positional relationship, be convenient for reach best radiating effect.
Furthermore, radiator fan includes that the interval sets up four small-size radiator fan on the roof, and not only small-size radiator fan low power consumption, the heat that produces are few, and be convenient for moreover corresponding with the heat dissipation air outlet of aeration fan converter, and the steam that rises can be under small-size radiator fan's effect, and a branch portion is discharged along with small-size radiator fan, and another part is discharged between the stand interval at lateral wall top. Compared with the use of a high-power radiating fan, the radiating fan saves energy, and can quickly radiate heat, and hot air below can be discharged between the stand columns more efficiently.
Furthermore, the cooling fan is an electroless exhaust fan, under the condition that the cooling fan corresponds to the cooling air outlet of the frequency converter of the aeration fan, the heat gas from top to bottom can drive the electroless exhaust fan to automatically rotate, and the heat gas in the cabinet body can be further extracted under the action of inertia after the electroless exhaust fan is started to rotate.
Further, the stand is threaded connection's stay bolt on the cabinet body, through the screw-thread fit relation of adjusting stay bolt and the cabinet body, can adjust the height of roof lifting, and then adjusts the hot hole height that scattered stand interval constitutes, can debug the cooperation relation of radiator fan and the heat dissipation air outlet of aeration fan whip piece ware when the installation to reach the best heat dissipation angle of airing exhaust, reach best radiating effect. The height of gauze is greater than the length of stay bolt, no matter how adjust the position of stay bolt, the gauze homoenergetic plays dustproof, prevents the effect of foreign matter.
The utility model discloses simple structure, can discharge the heat of the internal portion of cabinet high-efficiently, can reach the best radiating effect through the position of the relative cabinet body of regulation roof moreover, form the air current of natural emission, not only energy-concerving and environment-protective, dustproof moreover, prevent the foreign matter. Through the continuous seven days's in summer high temperature period measurement of nearly day, the internal temperature of current cabinet is 45 ℃, the utility model discloses the internal temperature of cabinet is stable at 31 ℃ basically, the utility model discloses the cabinet body descends 14 ℃ relatively current cabinet body, and the decline degree is up to 31%. The result of measured data shows that the utility model discloses the cooling effect is obvious effective. In addition, the utility model adopts the non-electric exhaust fan, which can save 946 kW.h of electricity consumption in one year.
