Fan housing and fan

Abstract

This application relates to the field of mechanical equipment technology, and discloses a fan housing and a fan. The fan housing includes a main body, a straightening member, and positioning components. The main body includes a straightening section; the straightening member is an arc-shaped plate with a straightening surface that abuts against the main body; the positioning components include multiple components, which are spaced apart between the main body and the straightening member along the extension direction of the straightening surface. The straightening member achieves the same roundness as the straightening section through the multiple positioning components. Compared with the prior art, the roundness of the straightening section is determined by the arc-shaped straightening member, and then the roundness of the straightening section is limited by the straightening surface formed after the straightening member abuts against the straightening section. The roundness of the straightening section is fixed by the multiple positioning components on the straightening surface, thereby limiting the roundness of the straightening surface between two adjacent positioning components, effectively improving the strength of the fan housing body and avoiding the problem of deformation of the fan housing body.
