Fin tube heat exchangers are the most widely used heat exchange equipment in air and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to the ordinary base tube. It achieves the purpose of enhancing heat transfer by adding fins to the ordinary base tube. The fluid in the finned tube heat exchanger tube is usually steam, thermal oil and water. With small air passage resistance, heat transfer for fin tube heat exhanger is efficient and stable. The steam or hot water flows through the steel pipe, and the heat is transferred to the air passing through the fins to achieve the function of heating and cooling the air.
