Abstract
The present utility model provides a fan cover shell and an air conditioning unit having the same. The fan cover shell includes an outer frame; multiple annular auxiliary reinforcement ribs, arranged from the center of the fan cover shell towards the outer frame; and multiple main reinforcement ribs, respectively extending from the center of the fan cover shell to the outer frame and intersecting with the auxiliary reinforcement ribs to form multiple ventilation grills; the main reinforcement rib forms a multi-section curve, and any adjacent curves of the multi-section curve bend towards a reverse direction. According to the fan cover shell of the present utility model, a better air guide effect is achieved by optimizing the main reinforcement ribs.
