Abstract
A tube and tube sheet assembly for a heat exchange device includes a plurality of heat exchanger tubes extending through a first and second tube sheet to provide a fluid-type passageway therebetween to enable a cooling fluid to be passed between the first and second tube sheets to reduce flashing of fluid introduced to the tubes. The fluid may be introduced into the tubes through the first tube sheet without turbulence or flashing because a smooth, continuous transition is provided therebetween by explosively forming the tubes within the tube sheet and providing openings communicating with each of the holes which are defined by the surface of revolution of an arc extending outwardly from the circumference of each hole to prevent formation of a Vena Contracta.
