Abstract
Abstract An injector type cooling apparatus is disclosed wherein multiple flat liquid sprays are directed into a conduit of uniform cross section to draw cooling air into and through the conduit for mixture with and heat transfer from the liquid. Air flow control strips are provided at the conduit inlet along with a special turbulence reducing air inlet slot. Also described is a dual level liquid collection means.
