Finned Tube Heat Exchanger
Air Heat Exchanger as Finned Tube heat exchanger
Gaseous medium and liquid
The heat transfer between finned tube heat exchangers is usually called air / water heat exchanger or gas / water heat exchanger. The heat transfer between gas (such as air) and liquid (such as water) occurs in the air / water heat exchanger. In order to improve the heat transfer from gas to liquid, fins made of well heat transfer material are placed on the pipe.
Generally, air / water heat exchangers are used as exhaust gas heat exchangers to obtain energy from warm or hot exhaust gases. Finned tube heat exchangers can also be used as air heaters, air coolers or condensers.
Finned tube heat exchangers have tubes with extended outer surface area or fins to enhance the heat transfer rate of the additional area of the fins. Finned Tubes or tubes with extended surface area can improve the heat transfer rate by increasing the effective heat transfer area between the tube and the surrounding fluid. The fluid around the finned tube may be processing fluid or air.
In order to design finned tube heat exchangers to increase the heat transfer area, the heat calculation of the required heat transfer area and the optimal spacing of tubes to create the required surface area are two parts of the problem. Increasing the heat transfer area means improving the efficiency of the heat exchanger.

Heat recovery with finned tube heat exchanger
Generally, air / water heat exchangers will be used for heat recovery. Warm exhaust gases (gases) that are often not used in the environment can be effectively used for heat recovery with the help of air / water heat exchangers. In this application, finned tube heat exchanger is also called economizer. In this case, other terms are preheater or heat exchanger.
Finned heat exchanger is the most widely used heat exchange equipment in gas and liquid heat exchangers. It can enhance heat transfer by adding fins to the common base tube. The base pipe can be steel pipe; Stainless steel pipe; Copper pipe, etc. Fins can also be made of steel strips; Stainless steel strip, copper strip, aluminum strip, etc.
The tube fin heat exchanger is commonly used in the air conditioning system. The working medium at the fin side is mostly air, and the tube is filled with water or refrigerant. The thermal resistance at the air side accounts for more than 70% of the total thermal resistance of the heat exchanger. Therefore, the heat exchange capacity of the air at the fin side is the standard to measure the efficiency of the heat exchanger.
In order to achieve the largest possible transfer surface inside the heat exchanger, fins
Put on the tubing system. The fins are pressed on the tube mechanically. Therefore, different materials can be combined. The materials for pressing fins (such as stainless steel, copper, aluminum) may vary in the height and thickness of fins and the distance between fins. Depending on the application, these parameters will be defined. The application of this type of heat exchanger can be found in process technology, food industry, air conditioning technology and many other industries.
Heat exchanger is the core equipment to realize heat transfer, and it has key applications in power system, metal smelting system, petroleum industry and other industries. Compared with plate and plate fin heat exchangers, finned tube heat exchangers are more widely used. At the same time, the tube fin heat exchanger has the advantages of easy production and assembly, low cost, etc.
