A tray-type fan impeller structure includes a plate body annularly disposed around a hub. The plate body has a connection side connected with the hub and a free side extending in a direction away from the hub. Multiple boss bodies are arranged on a top face or the top face and a bottom face of the plate body at intervals. By means of the boss bodies, the periodical noise problem caused by the conventional blades is improved.

Tray-type fan impeller structure

A disk-shaped fan impeller structure includes a plate body having an inner rim and an outer rim. The inner rim is connected with a hub via multiple connection members. The outer rim extends in a direction away from the hub. The connection members are annularly disposed on outer circumference of the hub at intervals to radially extend toward the inner rim of the plate body. A top face and a bottom face are defined between the inner rim and outer rim. Multiple upper boss bodies are arranged on the top face at intervals. Multiple first gaps are distributed between the upper boss bodies. By means of the boss bodies, the periodical noise problem of the conventional fan impeller can be improved.
