This type of cold storage system can solve the shortcomings of the first cold storage system mentioned above; however, the shortcomings of the cold storage system are: the motor 921 of the fan module 92 is integrated on the mesh cover 922, resulting in high production and maintenance costs of the cold storage machine 9, and the cold storage machine 9 is heavy, and the noise and vibration are large during operation; and the box body of the chassis 91 is an integrated structure, and the fan module 92 is basically an integrated structure, resulting in poor production flexibility when producing cold storage machines 9 of different numbers, and the fan module 92 is difficult to maintain and has high maintenance costs.
