Abstract

A cross-flow fan is composed of vane wheel unit consisting of multiple fans, motor, back guide surface, stabilizer, exhaust guide plate and internal guide plate. Its features are that there are lobeson said back guide surface, stabilizer, exhaust guide plate and internal guide plate for disturbing the eddy and turbulent flow to reduce noise.

Description

technical field [0001] The invention relates to a blower, in particular to a cross-flow fan. Background technique [0002] Blowers for air conditioners or refrigeration devices can generally be divided into centrifugal blowers, axial flow blowers and cross flow blowers, cross flow fans are cross flow blowers. The advantage of the cross-flow fan is that it can generate uniform high-pressure airflow in the axial direction, so it is widely used in air conditioners, especially window air conditioners and patio air conditioners. [0003] The following is a brief description of the structure of a common cross-flow fan with reference to the accompanying drawings: figure 1 As shown, a common cross-flow fan includes: an impeller component 110 , a motor (not shown in the figure), a rear guide surface 120 and a stabilizer 130 . [0004] The impeller part 110 includes: several unit fans connected in series by an annular boundary plate 120, each unit fan includes several blades 115 ben...
