In the scorching summer, there are many cooling devices, the most common of which are fans and air conditioners. In recent years, a type of water-cooled fan has become popular (many friends say this water-cooled fan is a combination of air conditioners and fans). So, is this water-cooled fan really good to use? In order to verify the practicality of the water-cooled fan, I specially bought one for experimentation. The one I chose is a relatively medium priced water-cooled fan, which costs around 300 yuan

The water-cooled fan has a relatively small size and light weight, with four wheels inside, making it easy to move and can be moved at any time as needed. The design is also varied. Usually, the water-cooled fan is a bit like a Water dispenser. I personally don't think it's appropriate to call a water-cooled fan an "air conditioning fan". Under normal circumstances, without adding water, the wind blown out by the water-cooled fan is basically the same as that of an electric fan. A water-cooled fan can add water, and the lower the temperature of the water, the cooler the wind blown out.

The method of adding water to a water-cooled fan is generally designed as adding water above or below, and there are also options for adding water both up and down. The water-cooled fan purchased at the same time will have several ice crystal boxes, which contain a small amount of ice crystals. We need to add water to the ice crystal box, and the ice crystals will expand in volume when they encounter water. Put the water filled ice crystal box in the refrigerator to freeze, and it will be ready to use in a few hours.
