The finned tube uses a high-frequency power supply as the heat source and fuses and welds the steel pipe into one body. The finned tube is composed of a heat dissipation inner core convection cover, which mainly uses convection heat dissipation. It has high heat dissipation efficiency, light weight, easy installation and maintenance, and is economical. Energy saving, environmental protection and other features.Most finned tubes use water, steam, and thermal oil as heat dissipation media. Through the heat dissipation of the media, the purpose of increasing the indoor temperature is achieved.Fin tubes use convection heating to continuously circulate heat in the room.The fin tubes are arranged horizontally, vertically or crosswise inside to reduce the thermal resistance of the radiator and improve the heat transfer coefficient of the radiator, thereby enhancing the heat dissipation effect.Fin tubes achieve the purpose of enhancing heat transfer by adding fins to ordinary base tubes.The base pipe of the finned tube can be steel pipe; stainless steel pipe; copper pipe, etc.Fins can also be made of steel strips; stainless steel strips, copper strips, aluminum strips, etc.A heat and cold exchanger that installs fins on the heat exchange tubes to increase the heat dissipation area.Common fin tubes in our lives are divided into square fin tubes, spiral fin tubes, longitudinal fin tubes, spiral serrated fin tubes, and inner fin tubes, which can be selected according to actual use needs.The material used for fin tubes is also related to the heat exchange effect of fin tubes. The fin tube materials are classified into single metal fin tubes and bimetal composite fin tubes.
