The invention relates to an automatic cleaning device for a surface air cooler at the
tail end of a central air conditioner and belongs to the technical field of cleaning of surface air coolers. The automatic cleaning device for the surface air cooler at the
tail end of the central air conditioner comprises fins which are arranged at intervals and cold water pipes which penetrate through the fins, are perpendicular to the fins and are arranged at intervals, wherein a water inlet is formed in one end of each cold
water pipe, a water outlet is formed in the other end of each cold
water pipe, cleaning
branch pipes which are arranged at intervals penetrate through the fins, one end of each cleaning
branch pipe is connected with a cleaning header
pipe, a plug is arranged at the other end of each cleaning
branch pipe, and a water orifice is formed in the portion, between every two adjacent fins, of each cleaning branch pipe. According to the automatic cleaning device for the surface air cooler at the
tail end of the central air conditioner, the fins can be cleaned and maintained effectively, and the cleanness and the smoothness of the fins are guaranteed. When the automatic cleaning device is used, a maintainer just needs to open a valve at regular times to wash the fins if possible, then the cleanness and smoothness of the fins can be kept for a long time, the situation that a special cleaning company is required for cleaning is avoided, and thus cleaning cost is reduced; when a large amount of dust is accumulated on the surfaces of the fins due to the absence of regular maintenance, chemicals can be injected into the cleaning header pipe for cleaning, and thus the fins can be thoroughly cleaned.
