Description

Technical Field

[0001] The utility model relates to the technical field of surface coolers, in particular to an automatic cleaning device for a surface cooler of an air-conditioning box. Background Art

[0002] There are two types of surface coolers: one is the fan coil heat exchanger, whose performance determines the fan coil's ability to transport cold (heat) and its impact on air volume. This device is generally available in central air conditioners. The other is the air-cooled fin heat exchanger in the air conditioning unit, which uses the refrigerant to absorb heat in the surface cooler to gradually reduce the temperature of the cooled space. This is the fan coil surface cooler of the air handling unit.

[0003] Publication No. CN203550763U discloses an automatic cleaning device for the fins of an air conditioner, which has the advantages of high cleaning efficiency, good effect and low investment cost. However, the cleaning device adopts a transmission mechanical vertical lifting and descending structure to make the nozzle on the surface of the spray pipe aim at the fins of the fins to spray the cleaning liquid. However, the models of air conditioner fins are different and the appearance is also different. During use, it is easy to have cleaning dead corners, which requires manual inspection and repair, which is time-consuming and relatively inefficient. To this end, we propose an automatic cleaning device for air conditioner fins. Utility Model Content
