Finned Heat Exchanger is the most widely used heat exchanger in gas and liquid heat exchanger. It can enhance heat transfer by adding fins on common base tubes. The base pipe can be steel pipe; Stainless steel pipe; Copper pipe, etc. The fins can also be made of steel strip; Stainless steel belt, copper belt, aluminum belt, etc.
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.
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.
Industrial finned tubes are different from domestic ones in that they do not excessively pursue beautiful appearance, and more requirements are better performance and longer service life, and they are selected according to regions and places of use.
1: Security
No matter what the scene and purpose, when selecting finned tubes, it is necessary to select finned tubes with high safety performance, and first select finned tubes that can ensure the safety of people and property.
2: Durability
For plants with particularly serious ash deposition, such as iron and steel plants and industrial kilns, large fin pitch shall be selected for heat exchange of finned tubes to minimize the loss of finned tubes, so as to maximize the durability and service life of finned tubes.
Determine the heat transfer required for finned tubes
The first step is to determine how much heat transfer is required and how many heat transfer surfaces are required. This will help determine which type of Fin Tube is the best heat dissipation solution, including the necessary fin surface requirements and the ideal material. What fin tube geometry is needed to achieve your vision?
You should also determine the necessary flow rate, which will affect the required diameter of the finned tubes. Which is affected by the pipe size.
how much pressure drop is required?
what hydraulic diameter is required?
what is the flow length on each fluid side of the heat exchanger?
what is the minimum free flow area?
what do you need in the forehead area?
what is the flow length on each fluid side of the heat exchanger?
Heat transfer can be improved by increasing the number of tubes or increasing the length of finned tubes.
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.
