Air fan cooler fin tube cleaning device for heat exchanger {APPARATUS FOR CLEANING FINNED TUBE OF AIR FAN COOLER FOR HEAT EXCHANGER}

The present invention relates to an air fan cooler fin tube cleaning device for a heat exchanger, and more particularly, an air fan cooler fin for heat exchanger, which is improved to remove only foreign substances accumulated on the surface of a fin tube at a time. It relates to a tube cleaning device.

In general, Finned Tubes for Air Fan Coolers for heat exchangers have thin fins on the tube surface to maximize the heat exchange effect when heat exchanging the tube side with air at the shell side. To form a, the heat exchange surface area is widened through the fin tube.

The fins of the fin tube mainly surround the tube with an aluminum material of about 0.4 mm in thickness, and a large amount of contaminants or foreign substances accumulate on the surface of the fin tube during heat exchange, and the air flows smoothly due to the foreign substances. The problem of air temperature rise occurs.

Due to such a problem, the heat exchange efficiency is lowered, resulting in energy loss. As a result, the energy consumption is increased, and the operation efficiency of the air fan cooler is lowered, which causes a problem in product production.

In order to solve the above problems, conventionally, the foreign substances such as dust are removed by using chemical reactions of chemicals, but the cleaning of the fin tube through the chemicals is possible only when the air fan cooler is stopped. There is a problem.

In other words, in the case of an operating air fan cooler, the dust and chemicals accumulated between the fin tubes are often evaporated before the reaction due to the operating temperature. There is a problem that is difficult.

In addition, the above chemicals may cause additional damage such as corroding and damaging the fin tube of the aluminum material for a long time, and in the case of the chemicals, there is a disadvantage that acts as a main cause of water quality and air pollution.

In order to solve the above problems, it is possible to clean and remove the dust of the fin tube even during the operation of the air fan cooler, and the mechanical cleaning device that does not cause damage or damage to the fin tube during the cleaning process and which is environmentally friendly. An air fan cooler fin tube cleaning device for heat exchangers has been devised.
