| description | The utility model discloses a pressure difference pre-cooling device capable of preventing wind short circuit, relates to the technical field of agricultural product cold chains, and aims to solve the problem of wind short circuit when an existing pre-cooling device is used for pre-cooling agricultural products. Comprising a box body and shielding pieces, a goods containing cavity and a static pressure cavity are formed in the box body front and back, the upper wall, the lower wall and the front wall of the goods containing cavity are open, the rear wall of the goods containing cavity communicates with the static pressure cavity through air holes, a centrifugal fan is arranged at the top of the static pressure cavity, and the shielding pieces are located on the left side wall and the right side wall of the goods containing cavity; the shielding piece is used for making contact with the side wall of the to-be-precooled goods placed in the goods containing cavity and blocking a short-circuit gap between the to- |
