Description

FIELD OF THE INVENTION [0001] The present invention relates to an air fan cooler for a heat exchanger,

The present invention relates to an air fan cooler pin tube cleaning apparatus for a heat exchanger, and more particularly, to an air fan cooler pin cleaning apparatus for an air fan cooler pin for a heat exchanger which can automatically remove foreign substances accumulated on a surface of a fin tube And a tube cleaning apparatus.

Air Fan Cooler for Heat Exchanger Finned Tube is used to heat the sensible heat of the tube side to the shell side air to maximize the heat exchange effect. And the surface area of heat exchange is widened through the fin tube.

The fin of the fin tube mainly surrounds the tube with an aluminum material having a thickness of about 0.4 mm. A large amount of contaminants or foreign substances are accumulated on the surface of the fin tube during heat exchange, and the air flows smoothly And there is a problem of rising the atmospheric temperature.

Such a problem causes a decrease in heat exchange efficiency, resulting in energy loss, resulting in an increase in energy consumption, lowering the operation efficiency of the air fan cooler and causing a problem in product production.

In order to solve the above-mentioned problems, conventionally, foreign substances such as dust have been removed by using a chemical reaction of a chemical agent. However, cleaning of the fin tube through the chemical agent is only possible in the case of the air fan cooler There is a problem.

That is, in the case of the air fan cooler in operation, the dust accumulated between the fin tubes due to the operating temperature often evaporates before the chemical reacts, which is not effective. There is a problem that it is difficult.

In addition, there is a concern that the above chemical agent may cause additional damage such as corrosion due to corrosion of a fin tube of an aluminum material for a long period of use. Further, in the case of a chemical agent, there is a malfunction which acts as a main cause of water quality and air pollution.

In order to solve the above-mentioned problems, it is an object of the present invention to provide a mechanical cleaning device which can clean and remove dust from the fin tube during operation of the air fan cooler and which does not cause damage or damage to the fin tube during the cleaning process, An air fan cooler fin tube cleaning device for heat exchangers was devised.
