Fanless cooling fan

A fanless cooling fan for household use is a type of electronic appliance that is designed to cool the air in a room without the use of traditional fan blades. Instead, it uses advanced technology such as evaporative cooling or thermoelectric cooling to lower the temperature of the air.

Evaporative cooling fanless fans work by drawing in warm air from the room and passing it over a wetted wick or filter. As the air passes over the wetted material, it evaporates and absorbs heat, which cools the air before it is blown back into the room. This type of fanless fan also adds moisture to the air, making it more comfortable and reducing dryness.

Thermoelectric cooling fanless fans, on the other hand, use Peltier effect to create a temperature difference between two sides of a thermoelectric module. When an electric current is applied, one side of the module becomes cold while the other side becomes hot. By placing the cold side in front of a heatsink and the hot side behind it, the fanless fan can cool the air without any moving parts.

Both types of fanless cooling fans are energy-efficient, quiet, and easy to maintain. They are ideal for use in bedrooms, living rooms, offices, and other small spaces where traditional fans may not be suitable.
