FIELD: heating.SUBSTANCE: fan designed to produce an air flow and comprising an air intake unit (20), an air outlet unit (14), an impeller (64) and a motor (68) intended for the rotation of the impeller to produce the air flow passing from the air intake unit to the air outlet unit. The air outlet unit (14) consists of an inner channel (94) intended to receive the air flow and an escape section (26) intended to release the air flow. The air outlet unit defines the hole (24) through which the air flow escaping the escape section sucks the air from the outside of the fan. The motor (68) comprises a rotor which can rotate with the speed of at least 5000 rpm when used. The air intake unit is placed in the side wall of the base.EFFECT: purpose of the said invention is to create a fan with smaller dimensions with no efficiency decrease.13 cl, 14 dwg |
