Abstract

A fan assembly, used to be mounted in a fan housing, includes a first air guide portion arranged in an air outlet of the fan housing; a fan wheel arranged on an end of the first air guide portion away from the air outlet; and a second air guide portion arranged between the first air guide portion and the fan wheel. An air outlet direction of the fan wheel at least partially overlaps with an air inlet direction of the second air guide portion, and an outlet direction of the second air guide portion is set at an angle with an inlet direction of the first air guide portion, the fan assembly is used to guide the air blown out by the fan wheel through the second air guide portion to reduce the airflow directly blowing to the first air guide portion.
