Abstract
A plate type heat exchanger in which liquid is injected into a vaporous fluid stream through orifices in a hollow slotted bar. The hollow bar is disposed transversely to the longitudinal axis of the heat exchanger, between and abutting facing surfaces of two metallic sheets. Vaporous fluid is admitted and distributed across the width of the heat exchanger in a first passage defined by the two metallic sheets, and flows through channels formed in the hollow bar where it abuts the sheets. The vaporous and liquid fluids mix, and after passing in heat transfer relationship with another fluid flowing in a second passage defined by adjacent metallic sheets, exit the heat exchanger. Since the hollow bar extends between the metallic sheets, it provides an effective structural support, permitting the heat exchanger to be used at relatively high operating pressures. In addition, the relative size and number of channels and orifices formed in the hollow bar control the ratio of the rate of flow of liquid and vapor through the heat exchanger.
