Fin tube heat exchanger is a heat exchanger for low temperature and high pressure, which is what we often call heat exchange equipment. It is mainly used for heat exchange in industry, generally for heat exchange, and is welded by multiple finned tubes.

Fin tube heat exchanger can be said to be a relatively new type of heat exchanger. It is an efficient heat exchange equipment with good heat transfer effect. The structure of finned tube heat exchanger is relatively simple, mainly composed of finned tubes and tube sheets. A heat exchanger is installed inside the finned tube to form a heat exchange cavity.

Fin tube heat exchanger can be used for heating, cooling, humidification or drying and other purposes. For the chemical industry, finned tube heat exchanger is a good heat exchange equipment, which can reduce the heat exchange amount, increase product quality and production efficiency.

Advantages of finned tube heat exchanger

Efficient and enhanced heat transfer ‌: The fins significantly increase the heat transfer area, which can improve the heat transfer efficiency in scenarios with low heat transfer coefficients. For example, in scenarios such as air conditioning condensers and boiler economizers, the heat transfer coefficient can be increased by more than 30%. ‌ ‌Compact structure design‌: Finned tube heat exchangers can achieve the same heat transfer load with fewer heat exchange tubes, thereby reducing the overall size of the equipment, reducing material consumption and installation space‌.
‌Adapt to complex working conditions‌: The fin material can be selected from copper, aluminum, steel, stainless steel, titanium, etc., suitable for complex environments such as high temperature, low temperature, and corrosive media. For example, stainless steel finned tubes can be used for heat exchange of chemical corrosive gases, while aluminum finned tubes are often used in low-temperature refrigeration systems‌.

Finned tube heat exchanger‌ Application scenarios

Finned tube heat exchangers are widely used in various industrial fields, including:
‌HVAC‌: such as the copper tube and aluminum fin structure of fan coil units, which are used for heat exchange between air and refrigerant‌.
‌Power engineering‌: such as the finned tube economizer of power station boilers, which recovers flue gas waste heat to heat feed water‌.
‌Refrigeration system‌: such as the finned tubes of cold storage evaporators, which enhance the heat exchange efficiency between refrigerant and air‌.
