The invention discloses a multi-cavity circulating ventilation type control cabinet and a production process thereof. The cabinet comprises a cabinet body, an
air chamber, a draught fan, a first through groove, a baffle, a support, dustproof cotton, a containing box, a
drying agent, a first plug pin, a first clamping block, a first sliding door, a first sliding groove, a first sliding rail, a second sliding door, a third sliding groove, a second sliding rail, a notch, a second cavity, a first sealing strip, a check block and a second sealing strip. The production process comprises the steps of: 1, manufacturing main components; 2, installing draught fan; 3, installing the sliding door; and 4, performing equipment inspection. Compared with an existing control cabinet, the control cabinet has the advantages that a circulating ventilation function is designed, circulating flow of air in the cabinet body can be achieved, the heat dissipation effect is improved, deposition of dust in the cabinet body is reduced, multiple cavities are designed, classified placement of equipment can be achieved, a sliding door device is designed, no extra space is occupied in the using process, and the multi-cavity circulating ventilation type control cabinet is suitable for various areas with narrow spaces.
