Thanks to the advancement of today's technology and equipment, our lives have become more and more convenient. However, as the performance of equipment increases and equipment becomes denser, the amount of work and heat generated also increases. Just like humans, the more work equipment does, the hotter it gets. If left untreated, this heat can lead to equipment failure or a shortened life span. This is why fans are needed to dissipate heat and lower the temperature.
In many cases, these fans are installed in places out of sight, and cool the inside of equipment continuously and unnoticed. They are the unsung heroes of our society that work behind the scenes to support our lives.
For example, you can find many fans in the convenience stores we visit in our daily lives. First, fans are used in ATMs, which have become commonplace in convenience stores. The control circuit inside an ATM is cooled by fans to prevent it from malfunctioning or failing from heat. Fans are also used in POS (point of sale) registers and surveillance cameras for the same application. Next, the fans in a copier are used not only to dissipate heat, but the blowing air is also used to feed paper piece by piece and to dry the deposited ink. Also, in food and drink showcases, fans are used to circulate the inside air to maintain a uniform internal temperature.
Fans may look simple, but as shown above, there are actually various types of fans depending on the application. So, it is important to learn how to properly select and use the right fan to make full use of it. Otherwise, you may encounter noise and other problems. Through the course of this series, we will be looking at fan features and characteristics, which are essential for making full use of fans.
