Abstract: A method of additively manufacturing parts by selectively cooling a liquefied thermoplastic material.

Abstract: A polymer tube dry cooling tower designed to operate with internal fluid at or near atmospheric pressure.

Abstract: A Thermal Bonding Method and Apparatus to thermally bond sheets of fill in a cooling tower fill pack. The apparatus creates a hemispherical joint extending through two fill sheets to provide a substantial joint between said sheets.

Abstract: A stacked tube heat exchanger consisting of tubes that are affixed to a header or headers that are additively manufactured.

Abstract: An internal melt ice thermal storage device having an ice build/melt coils with tubes fitted with extensions or “fins” that transfer heat from the thermal transfer medium in the tubes to distal portions of the ice rings that surround said tubes in order to define the shape of the liquid meniscus between the tube and ice allowing the ice to break free from the tube near the initiation of melt.

Abstract: A heat exchanger tube includes a tube body that forms a hollow passageway and has a U-shaped tube section defining a return bend and a pair of straight tube sections. Respective ones of the straight tube sections are connected to the U-shaped section at respective connection locations and extend generally parallel to one another to define an internal space disposed between and among the U-shaped tube section and the straight tube sections connected to the U-shaped tube section. The U-shaped tube section has a concavity formed thereinto with the concavity defining a portion of the internal space. A heat exchanger serpentine tube includes a plurality of straight tube sections arranged in a plurality of generally parallel rows and disposed in a common plane and a plurality of U-shaped tube sections connected to the plurality of straight tube sections to form a serpentine configuration.
