Storage refrigerator for express delivery

A storage refrigerator for express delivery comprises a refrigerator body and a refrigerator, and the refrigerator body comprises a plurality of cold grids and ventilation channels; the ventilation channel comprises a middle air channel and a rear air channel; at least one air inlet and at least one air outlet are preset in each cold grid; an exhaust port and an air return port are preset in the refrigerator; and the rectifying device comprises a backflow air duct and a rectifying air duct used for integrating air flow of the exhaust port. The number of the air inlets of the cooling grids with the lower height is larger, so that cold air flows into the cooling grids with the lower height more easily, and the problem that the flow distribution of refrigeration air flow of each layer is uneven due to different on-way resistance of the air flow of each layer is avoided; due to the fact that each air inlet is provided with the flow guide grid of the arc-shaped structure, cold air flows to the bottom of the cold g
