Where are the fans used?

When people hear the word "fan," many of them probably think of the ubiquitous electric fans and ventilation fans. These are also a type of fan, and their purpose is to lower the perceived temperature and ventilate. However, there are also fans that are useful in the world in ways that are not visible to the naked eye. These are fans that are installed in the devices and equipment around us, and are used to cool things and blow air.
In this section, we will learn the basic knowledge necessary to choose the best fan for your equipment.

The role of fans

In recent years, our lives have become more and more convenient as the performance of devices improves. However, as the performance of devices improves, the internal integration of the devices also increases, and the amount of work and heat generated also increases. Just like humans, the more exercise we do, the hotter we become. If this heat is left unattended, the equipment will break down or its lifespan will be shortened. That is why fans are used to release the heat and lower the temperature.
In many cases, fans are installed in inconspicuous places and continue to cool the inside of devices without people knowing. They are the silent heroes that support our daily lives, out of sight.

In everyday life

For example, fans are used extensively in convenience stores, which we often use in our daily lives. First, there are ATMs, which have become commonplace in convenience stores. The control circuits inside ATMs are cooled by fans to prevent them from malfunctioning or breaking down due to heat. Fans are also used in cash registers (POS systems) and surveillance cameras for the same purpose. Next, fans inside copy machines are used not only to exhaust heat, but also to feed each sheet of paper with air and to dry printed ink. Fans are also used in showcases that hold food and drinks to circulate the air to ensure that there are no uneven temperatures inside.

As you can see, fans may seem very simple, but in fact there are many different types depending on the application, and they are quite complex. If not used properly, the fan's performance may not be fully utilized, and it may cause problems such as noise. Through this corner, let's learn about the features and performance of fans and become able to use them properly.
