What is Low finned cooler tube?
Low finned cooler tube is the copper pipe with low fin used in evaporative cooler, which is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems using vapor-compression or absorption refrigeration cycles. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate, (that is, it has a large enthalpy of vaporization).
