Quickly learn what you need to know about heat exchangers.
A heat exchanger is a device that transfers heat energy from one medium to another. In factories, plants and vehicles, facilitating heat exchange is important to maintain the desired temperatures of the liquids and gases used in those systems. These might be water, oil, chemicals, for example.
Read more on our blog ‘What is a heat exchanger?’
Heat exchangers can be classified in different types such as their design (shell and tube, single tube) or whether a phase change occurs (such as in a condenser). Each type is suited to different purposes and applications. For example, compact fin heat exchangers help to save space through a compact design while still effectively transferring heat – very useful in marine or oil and gas applications.
To understand how different designs have different pros and cons, read “Types of shell and tube heat exchanger”.
The most common and versatile heat exchanger is the shell and tube design. These consist of a number of tubes contained within a cylindrical shell. They can be found in almost every industry, though in some (such as food and beverage), you are more likely to find single tube designs.
A condenser is a type of heat exchanger, too. Specifically, it is a heat exchange that cools down hot gas past its dew point, condensing it into liquid.
When high temperatures or corrosive materials are involved, there is a risk of corrosion and fouling, which can reduce the efficiency of a heat exchanger or cause leaks. However, a good cleaning schedule and routine servicing can avoid these problems.
