<p>A Cabinet in which a device room (A), a negative-pressure room (C) and a mixing room (B) are set. One or more heat emission components (2) could be arranged in the device room (A). The mixing room (B) is set in a side of the cabinet body (1), and on the mixing room (B) there are a reflux air opening (4) and an air inlet (10). A part of hot air from the device room (A) is discharged, and the other flows from the reflux air opening (4) into the mixing room (B) through a reflux air adjusting valve (5), and is mixed with cold air from the air inlet (10). Then it is sucked into the negative-pressure room (C) and subsequently into device room(A) to cool the heat emission components (2). At least one dust removing apparatus is set on the cabinet body (1) relative to the mixing room (B). The dust removing apparatus comprises a dust collecting board (6) which is set on the inner side of the cabinet body (1) and inclines upwardly. A dust removing opening (8) is set on the cabinet body under the slope formed by the dust collecting board (6). Dusts could slide down along the slope and be discharged through the dust removing opening (8). The cabinet is fit for both outdoor cabinet and indoor cabinet.</p> |
