Technical Field

[0001] This utility model relates to the field of fan side plate technology, specifically a cross-flow fan side plate. Background Technology

[0002] A cross-flow fan is a fan in which the impeller rotates under the drive of a motor, causing air to flow into the center of the impeller from the impeller inlet under the action of centrifugal force, forming a high-speed rotating airflow. Then, the airflow flows out from the impeller outlet. At the outlet, the airflow enters the diffuser and undergoes static pressure rectification, so that the airflow flows evenly to the fan outlet. At the same time, the airflow velocity is reduced, and its kinetic energy is converted into pressure energy. Finally, the airflow passes through a silencer to eliminate noise and is then transported to various points of use through ducts.

[0003] Currently, the side plates of cross-flow fans are installed with bolts, which makes maintenance of the cross-flow fans more troublesome. It requires workers to loosen the bolts to disassemble them, and repeated loosening of the bolts can easily strip the threads, leading to inconvenience in maintenance. Utility Model Content
