摘要

The present invention relates to a vehicle engine cooling fan, which comprises: a hub unit rotated by a motor; a blade unit having a first blade unit and a second blade unit, connected to the edge of the hub unit, and suppressing flow interference by using a height difference between the first blade unit and the second blade unit; and a ring unit connected to the end portions of the first blade unit and the second blade unit and covering the edge of the hub unit. Accordingly, a noise can be suppressed, and fan operation efficiency can be increased.;COPYRIGHT KIPO 2018
