Description

Technical Field

[0001] The utility model relates to the technical field of air coolers, in particular to an auxiliary air inlet device of an air cooler. Background Art

[0002] An air cooler is a mild cooling device that primarily cools the air by absorbing heat during the evaporation process. A traditional air cooler typically includes a water tank, a water pump, an air duct, a fan located within the duct, and a water curtain. Traditional air coolers are typically single-tank air coolers, with the water tank located below the water curtain. The water pump pumps the water from the tank to the top of the water curtain, causing some of the water on the water curtain to evaporate, making the air at the water curtain cooler. The fan then blows the airflow through the water curtain through the air inlet of the air duct to the air outlet of the air duct, making the air cooler and more comfortable, thus achieving an air cooling effect. However, when the air cooler circulates air between the air inlet and outlet through the fan, resistance is generated when the water curtain opens and closes, affecting the opening and closing effect of the water curtain and also shortening the service life of the fan.
