Abstract: A spiral heat exchanger features: a cold fluid inlet manifold, a hot fluid inlet manifold and at least one spiral fluid pathway. The cold fluid inlet manifold receives cold fluid and provide cold inlet manifold fluid. The hot fluid inlet manifold receives hot fluid and provide hot inlet manifold fluid. The at least one spiral fluid pathway includes cold spiral pathways configured to receive the cold inlet manifold fluid and provide cold spiral fluid pathway fluid, and hot spiral pathways configured to receive the hot inlet manifold fluid and provide hot spiral fluid pathway fluid. The cold spiral pathways and the hot spiral pathways are configured in relation to one another to exchange heat between the cold spiral pathway fluid and the hot spiral pathway fluid so that the hot spiral fluid pathway fluid warms the cold spiral fluid pathway fluid, and vice versa.

Abstract: A spiral heat exchanger features first spiral channels configured to form rows and columns of coiled hot fluid pathways to receive hot fluid; and second spiral channels configured to form corresponding rows and columns of coiled cold fluid pathways to receive cold fluid having a temperature less than the hot fluid. The first spiral channels and the second spiral channels are configured to alternate every other row and column so as to form a matrix of alternating rows and columns of coiled hot and cold fluid pathways separated by alternating coiled walls that act as both fluid separators and conduits through which heat is transferred between the hot fluid and cold fluid.

Abstract: A pump features a trimmed impeller having a trimmed impeller diameter that is less than a standard full-sized diameter of a standard full-sized impeller for a standard full-sized casing, and having a circumferential outer edge; and a modified standard full-sized casing having dimensions corresponding to the standard full-sized casing and configured to house the trimmed impeller for pumping a fluid, having an outer peripheral wall, and having an inner annular volute portion between the circumferential outer edge of the trimmed impeller and the outer peripheral wall configured with a volume of material deposited using an additive manufacturing process so as to fill in vacant space otherwise caused by the trimmed impeller diameter being less than the standard full-sized impeller diameter. The additive manufacturing process is a directed energy deposition.

Abstract: A pump features a two-part axial flow shaft having a static inner shaft portion and a rotating outer shaft portion; the static inner shaft portion having static diffuser vanes, and also having two shaft ends configured to affix to a frame of a pump so the static inner shaft portion does not rotate; and the rotating outer shaft portion having an outer portion configured to affix to a rotor of the pump to rotate the rotating outer shaft portion, also having rotating impeller vanes configured inside and coupled to the outer portion to move the fluid axially along the two-part axial flow shaft as the rotating outer shaft portion axially rotates in relation to the static inner shaft portion.
