Description

Technical Field

[0001] The utility model specifically relates to air outlet equipment for cold storage, and belongs to the technical field of air outlet equipment for cold storage. Background Art

[0002] Cold storage is an important part of the logistics industry. It can preserve food, fruits, vegetables, flowers and other products at a constant temperature and humidity, thereby effectively extending the shelf life of the products and improving the quality of the products. At present, the cooling method of cold storage is mainly air-cooled indirect cooling. Air-cooled cooling makes the temperature in the cold storage more uniform and the cooling is faster. Air-cooled cooling requires the installation of air outlet equipment to drive the flow of cold air so that the cold air is evenly distributed inside the cold storage.

[0003] As shown in the announcement number: CN220648752U, a cold storage air outlet structure is proposed to solve the problems that the existing air outlet size cannot be adjusted and the filter structure is easily blocked. The following scheme is proposed, which includes a cold storage air supply fan, and the air outlet on the right side of the cold storage air supply fan is connected to an air outlet hood, and a large conical gear is rotatably connected to the surface of the air outlet hood, and the axis at the rear side of the large conical gear penetrates the hole on the surface of the air outlet hood and is bolted with a movable wheel, and the left end of the axis at the rear side of the movable wheel is hinged with a hinged rod, and the right end of the hinged rod is hinged with a filter frame, the filter frame is slidably connected to the air outlet hood, and two guide plates can be driven to rotate through structural transmission, and the size of the air outlet can be adjusted by using the guide plates, so that the air volume and air speed can be controlled by controlling the size of the air outlet, and the filter frame can be driven to shake left and right through the structural transmission, and the dust on the filter frame can be shaken off by shaking to prevent dust from clogging the filter frame.

[0004] When using common cold storage air outlet equipment, although the size of the air outlet can be adjusted through the guide plate to control the air volume and speed, when adjusting the size of the air outlet, the air outlet is more concentrated, which makes it difficult for the cold air to diffuse evenly on both sides. Moreover, most air outlet equipment uses fixed air outlets, which makes the air outlet uneven and easily creates dead corners, resulting in a large temperature difference inside the cold storage, which can cause some food to be frozen.
