A heat exchanger (1) for thermally coupling a first fluid to a second fluid so as to transfer heat and in a fluidically separate manner includes a securing assembly (8) of two cover parts (9) and at least one, preferably a plurality of guide parts (11), through which duct tubes (5) of the heat exchanger (1) pass. The duct tubes (5) extend inside a housing tube (2) along the longitudinal axis of the housing tube (2). The first fluid passes through the housing tube (2) outside of the duct tubes (5), and the second fluid passes through the duct tubes (5). The duct tubes (5) may have circular or flattened cross-sections.

A system and method that uses a high-temperature condenser to collect magnesium produced by thermal reduction, electrolysis, or distillation. The condenser is a common heat exchanger design (shell/tube, plate/plate, etc.) and uses a heat transfer fluid to cool and condense magnesium gas, e.g., to 200-900° C. under vacuum or pressure conditions. Solid or liquid magnesium is collected in the condenser along with any by-products or impurities at a purity greater than 35 wt-% Mg. Magnesium is subsequently liberated from the condenser by raising the temperature of the system, lowering the pressure, or both, to induce a phase change in the metal, such as melting or distillation, for further purification to, e.g., >90 wt-% Mg.

A gas turbine engine is provided including a turbomachine having a compressor section, a combustion section, and a turbine section arranged in serial flow order; a rotor assembly driven by the turbomachine, the rotor assembly, the turbomachine, or both comprising a substantially annular duct relative to the centerline of the gas turbine engine, the annular duct defining a flowpath; a heat exchanger positioned within the annular duct and extending substantially continuously along the circumferential direction, the heat exchanger comprising a first material defining a heat exchange surface exposed to the flowpath, wherein the first material defines a heat exchange coefficient and wherein the heat exchange surface defines a surface area (A), and wherein the heat exchanger has an effective transmission loss (ETL) of between 5 decibels and 1 decibel for an operating condition.

A heat exchanging member includes: a pillar shape honeycomb structure having an outer peripheral wall and partition walls extending through the honeycomb structure from a first end face to a second end face to define a plurality of cells forming a through channel of a first fluid, and a covering member for covering the outer peripheral wall of the honeycomb structure. In a cross section of the honeycomb structure perpendicular to a flow direction of the first fluid, the partition walls includes: a plurality of first partition walls extending in a radial direction from the side of a center portion of the cross section; and a plurality of second partition walls extending in a circumferential direction, and a number of the first partition walls on the side of the central portion is less than a number of the first partition walls on the side of the outer peripheral wall.

The present invention concerns a heat-exchange element (31, 131) for a heat exchanger (1) enabling heat exchange between a first fluid and a second fluid, said heat-exchange element (31, 131) being designed to guide said first fluid through the inside of said heat-exchange element (31, 131) and said second fluid around the outside of said heat-exchange element, said heat-exchange element (31, 131) including at least one first duct (42, 43, 44, 45; 141, 142, 143) having a first essentially cylindrical wall and a second duct (42, 43, 44, 45; 141, 142, 143) having a second essentially cylindrical wall, the at least first and second ducts (42, 43, 44, 45; 141, 142, 143) being connected to one another by a portion of the first wall adjacent to a portion of the second wall.

A return waterbox for a heat exchanger, such as a shell-and-tube heat exchanger, is provided. The return waterbox may include an insert configured to direct a fluid flow(s) in the return waterbox. In some embodiments, such as in a two-pass heat exchanger, the insert can be configured to receive water from one portion of the heat exchanger tubes in the first pass and redirect the received water to another portion of the heat exchanger tubes in the second pass.

A heat exchanger includes a shell, a coiled tube, and a swirler. The shell has an inlet and an outlet and forms a cavity. A first of a liquid refrigerant and a vapor refrigerant enters the inlet of the shell. The coiled tube is positioned within the cavity and is connected to an inlet tube from outside the shell and an outlet tube to outside the shell. A second of the liquid refrigerant and the vapor refrigerant enters the inlet tube of the coiled tube. The swirler is arranged adjacent the inlet of the shell and is dimensioned to distribute the first of the liquid refrigerant and the vapor refrigerant across the coiled tube.
