As shown in fig. 1-2, the heat dissipation device for a switch cabinet of the present invention includes a cabinet body 1, a ventilation fan 3, a dust removal box 5, a filter box 6, a collection box 7, and a vibration device 11.

The cabinet body 1 is the major structure of cubical switchboard, and its inside is used for installing electrical apparatus cables such as control switch and wire, and its front is equipped with area locker door 2.

The ventilating fan 3 is installed at the top of the cabinet body 1 (installed in a preset hole at the top of the cabinet body 1) and used for exhausting air out of the cabinet body 1 (after hot air in the cabinet body 1 is extracted by the ventilating fan 3, cold air enters the cabinet body 1 under the action of atmospheric pressure to exchange heat with equipment in the cabinet body 1), and the ventilating fan 3 is used for providing assistance for the flowing (heat exchange) of the air in the cabinet body 1. The ventilator 3 is an axial flow fan. The top of the ventilator 3 is provided with a dust cover 4, and the dust cover 4 can prevent external objects (such as insects, particles and the like) from falling into the cabinet body 1.

The dust removing box 5 is integrally fixed at the bottom of the cabinet body 1; be equipped with air inlet 8 on the lateral wall before dust removal case 5 or the rear side wall, air inlet 8 comprises a plurality of length and width all is far greater than the bar hole of filtration pore 9, can ensure the smooth and easy entering dust removal case 5 of air. Be equipped with the mounting hole that is used for sliding collecting box 7 into dust removal case 5 below (air inlet 8 below) being located rose box 6 on the lateral wall before dust removal case 5, the mounting hole bottom surface flushes with dust removal case 5 bottom medial surface. The four corners at the bottom of the dust removing box 5 are provided with rollers with brakes, so that the cabinet body 1 can be moved conveniently.

The filter box 6 is fixed at the top of the inner side of the dust removal box 5, the top of the filter box 6 is provided with a ventilation port 10 communicated with the interior of the cabinet body 1, the ventilation port 10 is covered with a hollow cover plate 11 (to prevent objects in the cabinet body 1 from falling into the filter box 6), and a plurality of filter holes 9 with the aperture smaller than that of dust are arranged on the left side wall and the right side wall of the filter box 6 (to prevent the dust from entering the cabinet body 1, but the dust still blocks the filter holes 9, so a vibration device is arranged); the outer side wall of the filter box 6 is not in contact with the inner side wall of the dust removal box, an annular air inlet channel is formed between the outer side wall of the filter box and the inner side wall of the dust removal box, and air enters the air inlet channel from the air inlet 8 and then enters the filter box 6 from the air inlet channel.

The collecting box 7 is a hollow box body (similar to a drawer structure) with an opening at the top and capable of sliding into or out of the dust removal box 5 from the mounting hole, the collecting box 7 is positioned right below the filter box 6 and the air inlet channel after sliding into the dust removal box 5, and the outer side wall of the collecting box is in contact with the inner side wall of the dust removal box 5; a handle which is convenient for pulling out the collecting box 7 is arranged outside the collecting box 7. The purpose of the collecting box 7 is to collect the dust filtered by the filter holes 9 and the dust shaken off by the vibrating device 11.

The vibrating device 11 is arranged in the filter box 6 and can intermittently hit the side wall of the filter box 6, so that dust falls into the collecting box 7 from the side wall of the filter box 6; the two vibrating devices 11 are installed in the filter box 6 corresponding to the left and right side walls of the filter box 6, respectively. The vibration device 11 is composed of a motor and an eccentric wheel; the motor is arranged in the filter box 6; the eccentric wheel is installed on the motor shaft and can be driven by the motor to rotate and then continuously hit the side wall of the filter box 6, so that the side wall of the filter box 6 is vibrated and then ash removal is realized. The circle center of the eccentric wheel is positioned on the rotating shaft of the motor. The vibrating device 11 is arranged to prevent the filter holes 9 from being blocked and ensure the smooth ventilation of the filter holes 9.

The setting of rose box 6 in this application, aim at goes on in moving dust removal case 5 with the dust filtration process, and the dust of straining like this just directly falls to collecting box 7 in, concentrates the collection, avoids the dust to fall cabinet body 1 outside or depends on outside cabinet body 1, has guaranteed the sanitation outside the cabinet body 1. Meanwhile, due to the existence of the air inlet channel, when the vibration device 11 strikes the filter box 6 for dedusting, the vibrated dust can only fall in the dedusting box 5 and finally fall into the collecting box, and the dust can not be dispersed outside the cabinet body 1 to pollute the air.

When the air exchange fan is used, with the starting of the air exchange fan 3, hot air inside the cabinet body 1 flows out of the cabinet body 1 from the top of the cabinet body 1, cold air outside the cabinet body 1 firstly enters an air inlet channel of the dust removing box 5 from an air inlet 8 on the front side wall or the rear side wall of the dust removing box 5, then flows around the air inlet channel, enters the filter box 9 from filter holes 9 on the left side wall and the right side wall of the filter box 6, finally enters the cabinet body 1 from the air exchange port 10 to exchange heat with electrical equipment in the cabinet body 1, and is drawn out of the cabinet body 1 by the air exchange fan 3; under the pumping action of the ventilation fan 3, air continuously flows in the cabinet body 1, and the temperature in the cabinet body 1 is reduced. In the process that cold air passes through the filtering holes 9, dust mixed in the cold air is blocked outside the filtering box 6 by the filtering holes 9, one part of the dust falls into the collecting box 7, and the other part of the dust is blocked outside the filtering holes 9, so that the cold air is difficult to smoothly enter the cabinet body 1, and the heat dissipation effect is reduced; at this moment, the motor of the vibrating device 11 is started to drive the eccentric wheel to rotate ceaselessly, the side wall of the filter box 6 is hit with high frequency, dust attached to the side wall falls off from the filter holes 9, and smoothness of the filter holes 9 is guaranteed. The vibration means 11 are not operated all the time but are activated at regular intervals. The outer side of the collecting box 7 can be provided with a transparent window, and after a certain amount of dust in the collecting box 7 is reached, the collecting box 7 can be pulled out to remove the dust in the collecting box 7.

Other parts of the utility model not described in detail are conventional techniques known to the person skilled in the art.

The scope of the present invention is not limited to the technical solutions disclosed in the embodiments, and any modifications, equivalent substitutions, improvements, etc. made to the above embodiments according to the technical spirit of the present invention fall within the scope of the present invention.
