Embodiment Construction
[0044] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, but not all of them. Based on the embodiments in the present application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.
[0045] The existing outdoor units of air conditioners basically use axial flow fan blades, which have large air volume, high noise, and low static pressure. After the outdoor unit of the air conditioner has been in operation for a long time, the heat exchanger of the outdoor unit is prone to serious dust accumulation, resulting in heat t...

The invention relates to the technical field of air conditioners, and discloses a fan device of an outdoor unit, the outdoor unit and an air conditioner. The fan device comprise a centrifugal impeller for driving air flow, an air inlet flow guide part with an air inlet channel and an air outlet flow guide part, and the air inlet channel communicates to the air inlet position of the centrifugal impeller; a flow collecting cavity is defined by one end of the air outlet flow guide part, the centrifugal impeller is located in the flow collecting cavity, and an air outlet is formed in the other end of the air outlet flow guide part; and air enters the centrifugal impeller through the air inlet channel, and the centrifugal impeller exhausts air to the air outlet through the flow collecting cavity. The fan device is large in static pressure, the problems of surge or other abnormal noise caused by resistance increase due to dust accumulation of a heat exchanger or other reasons can be solved, and the normal air outlet amount of a fan can be guaranteed.
Description
technical field [0001] The present application relates to the technical field of air conditioners, in particular to a fan device for an outdoor unit, an outdoor unit and an air conditioner. Background technique [0002] The existing outdoor units of air conditioners basically use axial flow fan blades, which have large air volume, high noise, and low static pressure. After the outdoor unit of the air conditioner has been in operation for a long time, the heat exchanger of the outdoor unit is prone to serious dust accumulation, resulting in heat transfer failure. The resistance of the heat exchanger increases. At this time, due to the small static pressure generated by the axial flow fan blades, it cannot overcome the resistance of the heat exchanger well. The fan system will have surge or other abnormal noise problems, resulting in serious air volume attenuation and affecting performance. At the same time, the noise of the fan increases, which seriously affects the performan...
