What is Coil Heat Exchanger? Design Example

Coil Heat Exchangers

Welcome to Linquip Blog. Today and in this article, we are going to deal with Coil Heat Exchangers. The information in this article gives a significant collection of data you need to know about the structure, working principle, applications, and privileges of Coil Heat Exchangers. A coil heat exchanger is a type of heat exchanger, a device used to transfer or exchange heat or thermal energy with the help of coils.

Our team gathered all of the necessary information on this topic to eliminate the need for reading diverse content on other websites. Stay with us until the end to find the answer to your question on this topic.

An Introduction to Coil Heat Exchangers

Coil heat exchangers in their simplest form, use one or more tubes that run back and forth a number of times. The tube separates the two fluids. One fluid flows inside the tube and another flows on the outside. Let us have a look at a heating example. Heat is transferred from the hot inner fluid to the tube wall via convection, it then conducts through the pipe wall to the other side and the outer fluid carries this away also through convection.

The Coil Type Heat Exchanger produced by metal industries are suitable to transfer heat in a wide variety of operating conditions and to refuse to accept decay for the longest period of time possible under the harshest operating circumstances. Coil-type exchangers are more efficient than shell and tube exchangers for low flow rates. Due to their simple construction, they are low in price and easy to clean on the shell side. Thermal efficiency approximates that of a true countercurrent flow type exchanger.

Condensers are used for condensation vapors cooling liquids. Condensers are made by fusing a number of parallel coils in a glass shell. Coil Type Heat Exchangers are artificial to special requirements as to dimensional tolerances, finish and tempers for use in condensers and heat exchangers.

Copper heat exchanger tubes are normally supplied in straight length in annealed half-hard temper. Coil Type Heat Exchangers shaped by are metal industries not only have stiff tolerances the most dependable dimensions throughout the tube length. The tube surface is clean both inside. Coils are made in different diameters using tubes different bores.

The Applications of Coil Heat Exchangers

When it comes to heat exchangers, coil heat exchangers specifically are ideal for applications including boiler air preheating, pulp dryers, unit heaters, condensing and cooling as well as high-pressure, air tempering, and dryer applications. Depending on the application, there are many types and styles of coil heat exchangers to choose from.

Coil Heat Exchangers

Some of these include stainless tube bundles, double-pip heat exchangers, stainless steel tube immersion coil, bare tube immersion cooler, gas to water cooler, copper coil heat exchangers, combination ambient air/chiller water cooler, or coil tube-in-shell design to name a few. Each of these may also come in a variety of sizes and each has specific advantages. However, coil heat exchangers, in general, can be expected to have many advantages overall as well.

The Advantages of Coil Heat Exchanger?

Some advantages of coil heat exchangers include high efficiency, flexibility, low-pressure drop, they require little maintenance, are compact and lightweight, and are also easy and inexpensive to install. Coil heat exchangers tend to have higher efficiency than other types because of the large number of closely aligned tubes. This design aspect enlarges the heat transfer area, which results in a higher heat transfer co-efficient overall.

This efficiency equates to higher production while using less energy and that means big savings both upfront and in the long run. The coil-type heat exchanger is also known for being compact and lightweight due again to the closely packed tubes. The exchangers’ compact, lightweight design as well as their unique vertical orientation also means that they will take up less space and will be easier and less expensive to install. Their lightweight and compactness also lend to the flexibility mentioned earlier.

Another advantage of these heat exchangers is that there are many options when it comes to model types and configurations, which means they can be used with a wide variety of temperatures, flows, and pressures.

This flexibility equates to greater value overall. In addition to the benefits I just mentioned, coil heat exchangers also have low-pressure drops and require little maintenance as the structure of the tubes allows for turbulent fluid flow, which minimizes fouling and scales build-up. They can also be easily removed from the piping system to be flushed if that is necessary. Saving time and money both on installation and maintenance can go a long way for your business, and allows for overall smoother operations and less hassle and frustration.
