Evaporative water-air cooler - demister of high efficiency increases heat transfer

摘要

The cooler consists of at least one horizontal Venturi-tube with its associated spray jet device or individual jets respectively, a downstream mixing chamber, an air outlet arrangement including demister and a sump for the recovery of the water. The spray jet device covers the throat of the Venturi by a multitude of elliptical diverging jets provide the pumping action and bring about effective mixing of air and water. The demister consists of a multitude of shaped vertical strips and a arrests the water by impingement onto its baffled surface. The film running to the sump is additionally cooled contributing to the overall efficiency of the system.
