Abstract: In one aspect, a tubular membrane assembly is provided for a heat exchanger. The tubular membrane assembly includes a header having a header body, a tubular membrane, and a fitting connecting the tubular membrane to the header body. The fitting is configured to form a fluid tight connection between the fitting and the tubular membrane. The tubular membrane assembly further includes potting of the header keeping the tubular membrane connected to the fitting.

Abstract: In one aspect, a mass exchanger having an air inlet, air outlet, airflow generator, and a tubular membrane assembly. The tubular membrane assembly includes an inlet header, an outlet header, and a plurality of tubular membranes. The tubular membranes have side walls configured to facilitate mass transfer between air contacting the tubular membranes and working fluid in the tubular membranes. The inlet header includes an inlet header body having inlet header body openings with inlet end portions of the tubular membranes extending in the inlet header body openings and inlet header potting connecting the inlet end portions of the tubular membranes to the header body. The outlet header includes an outlet header body having outlet header body openings with outlet end portions of the tubular membranes extending in the outlet header body openings and outlet header potting connecting the outlet end portions of the tubular membranes to the header body.

Abstract: In one aspect, a hybrid heat exchanger that includes a metallic serpentine tube having an inlet end portion to receive a process fluid, an outlet end portion, and a series of runs and return bends directing the process fluid from the inlet end portion to the outlet end portion of the metallic serpentine tube. The hybrid heat exchanger further includes a thermally conductive polymer body thermally integrated with the serpentine tube. The thermally conductive polymer body has an outer surface to be contacted by a fluid, such as air and/or water. The thermally conductive polymer body is configured to transfer heat between the metallic serpentine tube and the fluid contacting the outer surface of the thermally conductive polymer body. The outer surface of the thermally conductive polymer body includes surface enhancement features that affect flow of the fluid across the outer surface of the thermally conductive polymer body.

Abstract: In accordance with one aspect of the present disclosure, a tubular membrane heat exchanger module is provided that includes an inlet header and outlet header. The inlet header is configured to connect to an adjacent upstream tubular membrane heat exchanger module and from an upstream wetted compartment therewith. The outlet header is configured to connect to an adjacent downstream tubular membrane heat exchanger module and form a downstream wetted compartment therewith. The tubular membrane heat exchanger module further includes tubular membranes connecting the inlet header and the outlet header. The tubular membranes facilitate flow of process fluid from the upstream wetted compartment to the downstream wetted compartment. Further, the tubular membranes permit mass transfer between the process fluid in the tubular membranes and a fluid contacting outer surfaces of the tubular membranes.
