Abstract

An improved convective heat transfer arrangement is disclosed achieving overall heat transfer efficiencies in the neighborhood of 30 Btu/(hr. ft.sup.2 .degree. F.). A heat transfer conduit including a heat transfer wall is axially divided into a plurality of axially extending heat transfer chambers by a plurality of transversely extending baffles. Each baffle is especially configured to have an axially extending recess formed therein through which extends an orifice opening. Heat transfer gas pumped through the conduit cascades through the heat transfer chambers forming and reforming nascent free standing jet streams through each baffle orifice which impinge the heat transfer wall to achieve very high heat transfer coefficients while efficiently utilizing the available heat in the heat transfer gas.
