Unique Design Portable Fan, Personal Hand Fan and Neck Cooler fan

They sit around your neck and continuously blow cool air onto your skin, which can help keep you feeling cool on the hottest days

“Neck fans” are a popular item in the summer which can be worn around the neck and help fight off heat. Without having to be handheld, the gadget is praised as a clever invention by those who want a cooling breeze just for themselves while on the go, such as joggers, delivery workers or just outdoor lovers.

The faster moving air from the fan displaces the warmer air that is in direct contact with our skin. This enhances the rate of convective heat transfer, which means we feel cooler. Moisture in the form of sweat on our skin also evaporates more quickly in the presence of fast moving air.

It also increases heat convection by displacing the warmer air produced by body heat that surrounds the skin, which has an additional cooling effect, provided that the ambient air temperature is lower than the skin temperature
