Axial fans and window air conditioners

Abstract

The invention discloses an axial-flow fan and a window-type air conditioner. The axial-flow fan comprises: an impeller and a water-pulling ring connected to the outer edge of the impeller; the water-pulling ring is provided with a water-pulling channel, and the water-pulling channel is along the axial flow fan The wind direction runs through the water circle. In the above-mentioned axial flow fan, in the process of the water blowing ring rotating with the impeller, the condensed water will enter the water blowing channel, and the condensed water located in the water blowing channel is thrown to the air outlet side of the axial flow fan under the action of centrifugal force, which increases It increases the amount of water pumped, improves the heat dissipation effect of the condenser, and then improves the energy efficiency of the window air conditioner; it also reduces the cost of using the window air conditioner; since the water pumping channel runs through the water pumping ring along the wind direction of the axial fan, condensation will occur. The centrifugal force on the water is large, which increases the distribution range of the condensed water on the outlet side of the axial flow fan, increases the heat dissipation area of ​​the condenser, and further improves the heat dissipation effect of the condenser and the energy efficiency of the window air conditioner. The window air conditioner disclosed in the present invention has the above-mentioned 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
