Description

Cabinet ventilation device and cabinet

technical field

The utility model relates to a ventilation device for a cabinet, and also relates to a cabinet using the ventilation device. the

Background technique

The ventilation device is an important facility of the equipment cabinet, which directly affects the ventilation, cooling and waterproof and dustproof of the equipment in the cabinet. Existing cabinets usually adopt the structure of adding an internal waterproof cover on the rear side of the louvered vent. This kind of cabinet ventilation structure has the following defects:

First of all, since the vent of the cabinet shutter is directly opposite to the internal waterproof cover, the air duct can only be set as the gap between the upper part of the waterproof cover and the cabinet door or the side wall of the cabinet. The air intake volume of the air duct is usually difficult to meet the ventilation and cooling requirements, which keeps the internal temperature of the cabinet at a high temperature and shortens the service life of the cabinet equipment and cabinet ventilation fans. the

Secondly, since the junction between the waterproof cover and the cabinet door or side wall of the cabinet is usually sealed and waterproof by applying waterproof sealant or installing a waterproof sealing strip, the waterproof sealant or waterproof sealing strip is soaked in water and weathered by the vent after a period of time , there will inevitably be water seepage and water leakage, which seriously threatens the safety of the cabinet equipment. the
