    摘要: A diagonal ventilating fan (30) has a fan housing (36) and a fan wheel (80), rotatable around a rotation axis, that has associated with it an electric motor (73) to drive it, the fan wheel (80) extending in the direction of the rotation axis between an air inlet side and an air outlet side of the diagonal ventilating fan (30) and serving, as it rotates, to convey air in a main delivery direction from the air inlet side to the air outlet side. The fan wheel (80) has a preferred rotation direction so that, during operation, its blades (82) each have a front side and a back side, and a negative-pressure zone (110) occurs, during operation, adjacent each respective back side of a blade (82). An auxiliary cooling air blower (76) connects to the respective zones (110) to provide an improved flow of cooling air for the electric motor (73).
