Mass transfer device having a heat-exchanger

A mass transfer device comprising:

• a housing having an upper hollow portion and a lower hollow portion, said lower hollow portion being in flow communication with said upper hollow portion;
• a mass transfer means located within said upper hollow portion of said housing, said mass transfer means having an inner surface and an outer surface;
• a heat exchanger located within said lower hollow portion of said housing, said heat exchanger comprising a core having an inner surface and an outer surface, said core being made from a generally cylindrical piece of corrugated metal of substantially constant thickness constructed and arranged to provide a plurality of corrugations, each of said corrugations having an outer wall, an integral first side wall, an integral inner wall, and an integral second side wall, said first and second integrgal side walls being substantially parallel to each other;
• a fluid manifold disposed within said core of said heat exchanger, said fluid manifold defining a first longitudinal slot communicating said fluid manifold with the inside of said core and a second longitudinal slot communicating said fluid manifold with the inside of said core, with the first and second slots being on opposed sides of the manifold, said manifold having an intermediate wall which defines a first manifold chamber communicating with the first slot and a second manifold chamber communicating with a second slot;
• a first fluid outlet projecting from said upper hollow portion of said housing and in fluid communication with said outer surface of said mass transfer means;
• a first fluid inlet projecting from said lower hollow portion of said housing, said first fluid inlet being in fluid communication with said outer surface of said core of said heat exchanger, said first fluid inlet and first fluid outlet being positioned to define a flow path therebetween via said outer surfaces of said core and said mass transfer means;
• a second fluid outlet projecting from said lower hollow porton of said housing;
• a second fluid inlet projecting from said lower hollow portion of said housing, said second fluid inlet and said second fluid outlet being in fluid communication with said inner surface of said core of said heat exchanger;
• said fluid manifold being configured so that a second fluid will move via said second fluid inlet into said first manifold chamber, through said first slot, around the outside of the fluid manifold into said second slot, out from said second manifold chamber and out of said heat exchanger via said second fluid outlet;
• a third fluid outlet projecting from said upper hollow portion of said housing;
• and
• a third fluid inlet projecting from said upper hollow portion of said housing, said third fluid inlet and said third fluid outlet being in fluid communication with said inner surface of said mass transfer means.
