A cooling fan is a device that helps regulate temperature by moving air. It is commonly used in various applications, such as in computers, home appliances, and vehicles. By circulating air, cooling fans help dissipate heat, preventing overheating and maintaining optimal operating conditions. Cooling fans come in different sizes and types, including axial fans and centrifugal fans. They can be powered by electricity or batteries and are often equipped with adjustable speeds. In addition to cooling, they can also improve air circulation and ventilation in enclosed spaces, contributing to overall comfort and efficiency.
