CENTRIFUGAL FAN WITH DOUBLE AIR INLETS AND DOUBLE AIR OUTLETS
Document Type and Number:
WIPO Patent Application WO/2019/056676
Kind Code:
A1
Abstract:
Provided is a centrifugal fan with double air inlets and double air outlets, comprising a volute casing (10), a motor (20) and a centrifugal wind wheel (30), wherein, the volute casing (10) comprises an upper casing (11) and a lower casing (12) coupled to the upper casing (11); the upper casing (11) and the lower casing (12) are each provided with an air inlet (13), and the motor (20) is installed between the upper casing (11) and the lower casing (12); the centrifugal wind wheel (30) is coupled to the motor (20), the volute casing (10) is provided with a wind deflecting plate (14), and a double air duct (40) is formed between the air deflecting plate (14) and the centrifugal wind wheel (30); and an air outlet (15) is provided on an outer side of the double air duct (40). The centrifugal fan realizes that the wind enters from two directions and exits from two directions, and the air inlet and outlet areas are large. When the fan rotates once, it can achieve twice wind-outs in the direction of 180 degrees. The ventilation efficiency is high, the power consumption is low, the noise is small, realizing small volume and large air volume and wide range of application.
