Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, an active filter cabinet of the present invention includes a cabinet body 1;
as shown in fig. 3 and 4, a plurality of heat dissipation through holes 8 are formed in the front side wall and the rear side wall of the cabinet body 1, and filter screens are arranged on the heat dissipation through holes 8, so that the heat dissipation through holes play a role in heat dissipation, and the filter screens on the heat dissipation through holes 8 can effectively prevent dust from entering the cabinet body 1; as shown in fig. 1, a plurality of partition plates are horizontally installed in the cabinet body 1 at equal intervals from bottom to top, the partition plates form three active filter installation areas 2 on the lower portion of an inner cavity of the cabinet body, and the three active filter installation areas 2 are used for installing active filters; all be equipped with first cooling fan 11 in every active filter installing zone 2, active filter during operation in the cabinet body 1, three first cooling fan 11 start, will be located the outer air suction of the preceding lateral wall on the cabinet body 1 to the cabinet body 1 in, the hot-air of the internal 1 of cabinet is discharged from the heat dissipation through-hole 8 on the back lateral wall of the cabinet body 1, plays the radiating effect. A cabinet door 10 is mounted on the front side wall of the cabinet body 1. The upper portion of the cabinet body 1 is provided with a cable inlet hole 5, and a cable outlet hole 7 is formed in the bottom wall 6 of the cabinet body 1, so that wire arrangement is facilitated.
In this embodiment, two fan brackets 9 are arranged at the upper part of the inner cavity of the cabinet body 1, second heat dissipation fans are respectively mounted on the two fan brackets 9, a temperature sensor 3 is arranged in the cabinet body 1, and the temperature sensor 3 is in signal connection with the two second heat dissipation fans; when the temperature in the cabinet body 1 reaches the set numerical value, the temperature sensor 3 sends a signal to the two second cooling fans, the two second cooling fans are started to work together with the three first cooling fans, and the temperature in the cabinet body 1 is cooled.
Further, still be equipped with alarm 4 in the cabinet body 1, temperature sensor 3 with alarm 4 signal connection, when the temperature in the cabinet body 1 reached the alarm temperature of settlement, temperature sensor 3 signals for alarm 4, and alarm 4 sends the police dispatch newspaper, reminds staff's the internal temperature of cabinet to reach dangerous value, needs shut down the cooling and overhaul.
When the active filters are installed, the active filters are installed in the three active filter installation areas 2 according to the requirement, namely the number of the active filters which can be installed is 1, 2 or 3; the three active filters are mutually connected in parallel, and have no influence on each other; all be equipped with first cooling fan 11 on every active filter installing zone 2, play good radiating effect to the cabinet body 1.
