Abstract
A cooling tower includes a cover and a heat exchanger positioned within a water circulation channel in order to exchange heat between water and air through contact with air. A closed housing is positioned within the cover, and the heat exchanger is positioned within and maintained in an airtight state within the housing. An air supply duct is in communication with the housing for supplying air, and an exhaust duct is in flow communication for exhausting air from the housing. A blower generates air flow in the air supply duct, the housing, and the exhaust.
