Finned Tube Heat Exchanger An Brief Overview

Finned Tube Heat Exchanger

In this hot summer, we are sitting in a chilled room. Have you ever thought about how it is possible? That is because of heat exchangers. Heat exchanger applications are not only in domestic appliances but also in crucial industrial manufacturing sectors. They transfer heat between hot and cold streams to save energy. A heat exchanger with fins attached to the outer tube is known as a Finned Tube Heat Exchanger. In these heat exchangers, fins increase the surface area for heat transfer, which increases the rate of heat exchange.

What are Finned Tube Heat Exchangers?

Finned tube heat exchangers are the type of heat exchangers in which fins are attached to the outer tube of the exchanger. Adding fins facilitates the transfer of fluid outside the tube. It is for the transfer of air or another gas. 

In a finned tube heat exchanger, an overall flow pattern is often crossflow, but it can also be counterflow or parallel flow.

A finned tube is very helpful as one of the fluids is air or any other gas in an air heat exchanger. There is a low air-side heat transfer coefficient, which increases the surface area of heat transfer.


Why Finned Tube Heat Exchangers are made of Aluminum?

  • Aluminum is a lightweight metal than heavier metals like stainless steel or copper. In the case of radiators, the lightweight material improves the performance of the equipment.
  • Aluminum is a great heat conductor, making it an excellent choice for radiators. While comparing to other materials, aluminum radiators heat efficiently and quickly reach the necessary temperature.
  • It is a recyclable metal. So by buying aluminum radiators or fin tubes, you are getting an eco-friendly product.

Working Principle Of Finned Tube Heat Exchangers

In a finned tube heat exchanger, fins are outside the tubes. The liquid will flow through the finned tube with air or another gas flowing outside, increasing the heat transfer rate due to the greater heat transfer surface area.

The fins on a crossflow tube exchanger are usually circular or square radial fins. Fins should be longitudinal rather than radial in a counterflow or can be parallel flow fin tube exchangers. In an enclosed heat exchanger, finned tubes work as internal tubes. 

Uses Of Finned Tube Heat Exchanger

  • Finned tube heat exchangers are helpful in the condition where the heat transfer coefficient inside the fluid is higher than the fluid outside the tube. 
  • Other finned tube air heat exchangers include automobile radiators. The truck radiator‘s job is to cool the hot water in the tubes by circulating air through them in a crossflow pattern. Also, the objective of the air conditioner evaporator coil is to condense the air traveling through it.
  • Finned tube heat exchangers are helpful in the chemical industry, petrochemical industry, automobile (heavy truck radiators, car radiators) industry, etc.
  • Recent developments have seen dry cooling for steam power plants grow rapidly. In this method, an air-cooled condenser replaces a water-cooled condenser.
  • For different purposes, the shapes and sizes of fins are unique, like- S-shaped fins to increase the surface area for heat exchange in heavy truck radiators to increase the heat transfer rate. Therefore, these are the best truck radiators in use nowadays.

Fin Tube Radiator: An Overview You Need To Know

fin tube radiator

However, you may wonder what the purpose of these fin tubes is and why these fin tubes are used in the exchangers. The Fin Tube Radiator is generally used in Heat Exchangers. This piece of thread will clear all your doubts about the usage, structure, and working of the Radiator.

What Are Fin Tubes?

A finned tube is made from elongated flat tubes made from aluminum-clad carbon steel and brazed aluminum fins. The finned tube radiator is the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to the standard base tube. These heat-transmitting fin tubes are nestled inside the casing, which consists of steel plating and insulation.

The base pipe can be steel pipe- stainless steel pipe, copper pipe, and so on. Fins can also use steel strips, stainless steel strips, copper strips, aluminum strips, etc.

Fin tube heat exchangers are used in household appliances and industrial heat exchangers, while car radiators and air conditioners use Fin tube heat exchangers.

The main reason to employ a fin tube is that the air passing through the tube is supposed to be cooled.

As in a car radiator, the air passes through the tube in crossflow. This supports cooling the liquid inside, and the advantage of fins over ordinary tubes is that they provide more significant contact with the liquid outside. Also, this allows for quicker heat exchange between the inside and outside of the tube.  

Uses Of Fin Tube Radiator

  • A finned tube is extremely helpful when the airside heat coefficient is lower, and as a finned tube increases surface area, this facilitates faster heat transfer between components.
  • The most widely used finned radiator is the steel-aluminum finned tube (finned steel-aluminum composite finned tube, rolled finned steel-aluminum composite finned tube), which utilizes the pressure resistance of the steel tube and the high efficiency of aluminum. The thermal conductivity is compounded on a particular machine tool. 
  • The steel-aluminum composite tube radiator has irreplaceable advantages over other finned tube radiators.
  • The finned tube radiator is generally used for heating or cooling air and has the characteristics of a compact structure and large unit heat exchange area. Widely used in textile, printing and dyeing, petroleum, chemical, drying, electric power, and other fields.

Advantages of Using Finned Tubes

  • Increase Heat Transfer Rate

The fins in a finned tube enhance the surface area of contact. This permits it to quicken the heat transfer rate.

  • Improve Heat Transfer Coefficient

In an ordinary tube, the external surface area is just about the same or slightly different from the internal surface area. In such a case, the fluid with the smallest heat transfer coefficient will drive the entire heat transfer rate. A finned tube enhances the surface area fundamentally. This is especially useful when the heat transfer coefficient of the fluid inside the tube is more prominent than that of the fluid external to the tube.

  • Reduces Size of the Equipment & Makes Project Cost Efficient

Finned tubes can essentially expand the surface area. The utilization of a finned tube can cut down the number of tubes used in an application. These outcomes in a considerable decrease in the size of the equipment. In the long run, this can lead to a reduction in the cost of the project.

Selection parameters of fin tube heat exchanger

How to select a Fin Tube Heat Exchanger is indeed a question that consumers need to think about.

Some focus on thermal efficiency & care about whether they can obtain obvious outcomes in a short time; some focus on corrosion resistance due to environmental factors; & whether the shape is beautiful in mishaps. 

(1) The working pressure of the finned tube radiator should meet the working pressure of the system and comply with the current national product standards;

(2) Industrial buildings with high requirements for dust emission or dust prevention should use finned tube radiators that are simple & easy to clean;

(3) Corrosion-resistant finned tube radiators should be used in industrial buildings with corrosive gases or in environments with high relative humidity;

(4) When using steel finned tube radiators, a closed system should be adopted and meet the product’s water quality requirements.

(5) When using aluminum finned tube radiators, internal anti-corrosion aluminum Fin Tube Heat Exchanger should be used, and meet the product’s water quality requirements;

(6) Choose a regular finned tube radiator manufacturer, with better after-sales guidance, installation, and technical support. 

Why Use Aluminum Fins?

According to the heat exchange application and operation, there are different materials.
