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.

1. A cross-flow fan comprising:a casing located at a downstream side of a heat exchanger and for forming an air passage; a bladed wheel contained in the casing; a motor for rotating and driving the bladed wheel; and air being sucked in the casing by rotation of the bladed wheel through the heat exchanger so that ventilation is made for the heat exchanger; wherein: an opening portion for ventilation is bored in a wall surface of the casing; and the casing includes a partition portion for partitioning the air passage into an intake side and a discharge side, with a tongue portion close to an outer periphery of the bladed wheel as an apex, and the opening portion is bored in the wall surface forming this partition portion.
