A Tube Heat Exchanger: What is it and How Does it Work

As you already know, the tech world is constantly evolving and changing, hence, it is completely normal if you have not heard about a little thing called a tube heat exchanger. And if you are unfamiliar with the entire concept of this device, this article is made for you. In the text below, you will be able to find out what this device is, its design features and types, as well as how does it work. Let’s take a closer look at this guide:

What is it?

Since this might be the first time you are learning more about this device, let’s start simple. Tube heat exchangers are devices that are made for transporting heat from one matter to another without the matters ever coming in contact with one another.

So, all the liquids, gases, or other materials passing through the tubes do not mix together. When it comes to the uses of these devices, they are commonly used for various processes that require a higher temperature, as well as pressure processes. And thanks to the device’s design and shape, they are quite resistant. Since they come in different forms, different industries can easily find one that will fit the specific needs of their processes.

These machines can be utilized for various operations. For example, they are applied in processes such as heat waste recovery and heat removal and can be found in transmission and boiler coolers, air conditioners, hot tubs, and engine coolers as well. Some industries that implement these devices into their facilities include:

1. Commercial and Manufacturing Industries
2. Cooling and Heating Industries
3. Marine Industries
4. Aerospace Industries
5. Waste Treatment Industries
6. Automotive Industries
7. Pharmaceutical Industries
8. Food Processing Industries

The Design

There is a wide range of tube heat exchanger designs, however, the most common ones are the straight-tube, spiral, and U-tube heat exchanger. According to the experts from Exodraft, although they might look quite different, their parts do not differentiate from one another. All tube heat exchangers will have a shell that is used for holding the internal parts, as well as a tube that holds a substance that needs to be cooled down or heated up. There is also another tube which is used for holding a matter which allows the other matter to be heated or cooled.

How it Works

As previously mentioned, the different types will look different, however, they do work in the same principle. For the energy transmission to occur, the second tube – which is the one that allows the medium to be heated or cooled – needs to be placed over the first tube. The material used for making the tube walls is usually metal and they act as a conductor that links the two substances. And in order for the process to be finished, the thermal energy needs to go from the cooler to the hotter substance or vice versa.


These heat exchangers are used for a wide range of applications and if you want one implemented in your facility, do not waste any more time and start searching for one that will fit your requirements.
