Fluid Cooling System Particularly for Cooling Towers

Abstract

A fluid cooling system has a liquid distribution system with feed pipe and distributor pipes connected thereto. The distributor pipes have full cone nozzles tangentially attached to the distributor pipes. The full cone nozzles each have a nozzle housing that has a rotation-symmetrical nozzle chamber with a rotational vertical axis, a connecting piece opening into the nozzle chamber, a nozzle mouth located downstream of the nozzle chamber and defining an outlet port, and a housing lid closing the nozzle chamber. The housing lid has an inside and extensions supported thereon, wherein the extensions face the nozzle chamber and project into the nozzle chamber. The connecting piece is positioned at a right angle relative to the rotational vertical axis and is offset relative to this axis. The outlet port is offset relative to the rotational vertical axis, in a direction toward the connecting piece.
