Air supply plate

The utility model provides an air supply plate, which is characterized by including a plate-shaped wall body and bosses mounted on the wall body, wherein a plurality of holes are formed in the wall body; the bosses are designed into conical cover bodies with bigger air inlets and smaller air outlets; the air inlets of the bosses coincide with the holes and are mounted on the wall body; the to-be-supplied air behind the wall body is blown out from each hole of the bosses, so that the air outlet points are uniformly distributed and the transverse and the vertical temperature and humidity fields of the whole space are ensured to be uniform. As the bosses are designed into the conical cover bodies, the air supply distance is ensured to be long, the air velocities at the outlets are reduced, the noise caused by air flowing is reduced, and the indoor air is effectively ensured to be stable and uniform. The air supply plate provided by the utility model has ingenious design and simple structure, effectively meets th
