A mini handheld fan with semiconductor refrigeration technology is a type of portable cooling device that uses a small thermoelectric cooling module to generate cool air. The device is typically battery-powered and features a small fan that blows air over a heat sink, which is connected to the cooling module.

Semiconductor refrigeration works by exploiting the Peltier effect, which is a phenomenon where heat is absorbed or released when an electrical current flows across the junction of two different types of conductive materials.

In a thermoelectric cooling module, the current is passed through a series of alternating n-type and p-type semiconductor materials, causing one side of the module to absorb heat and the other side to release it. By using a small fan to blow air over the heat sink on the hot side, the device can generate a flow of cool air on the cold side.

Mini handheld fans with semiconductor refrigeration technology are popular for personal cooling in hot and humid environments, such as during outdoor activities or while commuting. They are typically small and lightweight, making them easy to carry in a pocket or purse, and they can provide a refreshing burst of cool air on demand. However, they are not intended for use in large rooms or for cooling down entire areas, as their cooling capacity is limited by their size and power source.
