ABSTRACT OF THE DISCLOSURE An apparatus is provided herein for heat exchange between two liquids without solid matters contained in the liquids. The apparatus comprises a pressure vessel which is divided into a plurality of compart- ments, each compartment comprising an inner space having an open end and an outer annular space. A baffle having a closed upper end is provided around the upper portion of each inner space with an annular slit between the baffle and the wall of the inner space. The baffle extends to a level below the upper end of the inner space. Injection nozzles for the heat receiving liquid are provided in the upper portion of the outer space of each compartment, and an outlet pipe is connected to the lower end of the outer space. Inlet and outlet pipes for the heat delivering liquid are connected to the upper and lower ends respectively of the inner space. The inner and outer spaces respectively are connected in series, and the heat delivering and heat receiving liquids are fed in countercurrent flow with respect to each other. The heat delivering liquid generates vapor that passes downwardly through the annular slit between the inner space and the baffle and then upwardly to meet droplets of the heat receiving liquid from the nozzles, This heat exchange appara- tus has several advantages, namely: several units are built in into one pressure vessel, whereby the costs both of the pressure vessels and of their supporting structures are substantially reduced; the cyclone part is completely enclosed with the pressure vessel and has no part in common with the pressure vessel wall; the expansion vapor is carried down into the condenser part so that countercurrent flow is accomplished in this part; and a plurality of nozzles is employed for distributing the suspen- sion in the condenser part, whereby better utilization of its volume is achieved.
