Axial flow fan and window type air conditioner

Abstract

The invention discloses an axial flow fan and a window type air conditioner. The axial flow fan comprises impellers and a water beating ring connected with outer edges of the impellers, wherein a water beating channel is formed in the water beating ring and penetrates through the water beating ring in the wind direction of the axial flow fan. According to the axial flow fan, condensate water can enter the water beating channel when the water beating ring rotates along with the impellers, the condensate water in the water beating channel is thrown to the air outlet side of the axial flow fan under the action of centrifugal force, the water beating capacity is improved, the cooling effect of a condenser is improved, the energy efficiency of the window type air conditioner is improved, and the use cost of the window type air conditioner is reduced. The centrifugal force borne by the condensate water is large due to the fact that the water beating channel penetrates through the water beating ring in the wind direction of the axial flow fan, the distribution range of the condensate water on the air outlet side of the axial flow fan is increased, the cooling area of the condenser is increased, and the cooling effect of the condenser and the energy efficiency of the window type air conditioner are further improved. The window type air conditioner is provided with the axial flow fan.

Description

technical field [0001] The invention relates to the technical field of window air conditioners, and more specifically, relates to an axial flow fan and a window air conditioner. Background technique [0002] Axial flow fans are used in window air conditioners to enhance the condensation and heat dissipation effect of the condenser. The chassis of the window air conditioner is equipped with a water storage area, and the axial flow fan is equipped with a water ring connected to the outer edge of the impeller. With the rotation of the impeller, the water ring will carry the condensed water in the water storage area to form water mist. The mist spreads to the surface of the condenser, which is used to increase the cooling rate of the high-temperature medium in the cooling condenser, thereby improving the heat dissipation effect of the condenser. [0003] At present, the water pumping ring is a ring-shaped plate, and the water is carried by the smooth circumferential inner wall ...

AI Technical Summary

Problems solved by technology

[0003] At present, the water pumping ring is a ring-shaped plate, and the water is carried by the smooth circumferential inner wall of the water pumping ring, so that the water pumping ring can carry less condensed water, that is, the amount of water pumped is small, resulting in poor cooling effect of the condenser , the energy efficiency of the whole window air conditioner is low
