Abstract:
A regenerative evaporative cooler, comprising:a regenerative evaporative cooling unit consisting of a dry channel and a wet channel arranged in the cooling unit to closely come into contact with each other, said dry channel being used for allowing primary air to pass through, said wet channel being used for extracting a part of the primary air from an outlet end of the dry channel so as to form extracted air flowing in the wet channel in a direction opposite to a flowing direction of the primary air, said cooling unit also including a plurality of cooling fins arranged in said dry and wet channels to allow the extracted air to come into direct contact with water so as to improve both water vaporization efficiency and water vaporization area in the wet channel; a first blower fan used for sucking the primary air into the dry channel of the cooling unit; a second blower fan used for sucking a part of the primary air of the dry channel into the wet channel so as to form the extracted air; and a water supply unit used for feeding water to said wet channel, whereby the extracted air flowing in the wet channel absorbs heat from the dry channel by means of the cooling fin of said wet channel, thus cooling the primary air flowing in the dry channel.
