Abstract
A heat transfer system for cooling water, comprising a relatively large air duct which is open to ambient air at the upstream end, where there is situated an annular, coaxial nozzle to jet hot water through a venturi tube toward the downstream end of the air duct. The high velocity stream of water draws air into the low pressure zone to intermix with the finely divided water droplets moving downstream. The water is cooled by transfer of heat of vaporization as well as by transfer from the air itself, whereby water drawn from the downstream end of the air duct is cool enough for recycling.
