An air cooler is a kind of cooler, which is characterized by using air as a heat exchange medium for heat exchange, and the heat is taken away by air. Generally speaking, the heat dissipation effect of the air cooler mainly depends on the heat exchange area and air volume of its component radiator, for the same heat exchange area, the larger the air volume, the better the heat dissipation effect. For the same air volume, the larger the heat exchange area, the better the heat dissipation effect.
