Abstract
A cross-flow fan is provided in which air movement is increased without increasing the power of the motor. Opening portions for ventilation are bored wall surfaces forming a stabilizer in the casing of a cooling fan. These bores are at positions separated from the tongue portion by predetermined distances. When a bladed wheel is rotated by a motor, air is sucked from the front side of a core portion through the core portion and into the inside of the casing. The cooling fan generates, in the inside of the casing, a simple flow passing through the bladed wheel to a discharge port. This flow has a circulation flow (swirl) circulating within the bladed wheel.
