Evaporator with finned channels

A cooling system, comprising:

• a main body extending between a first end portion and a second end portion;
• an inlet port extending outwardly with respect to an outer surface of the main body;
• a first plurality of fins extending outwardly from the outer surface of the main body, defining a first number of microchannels between adjacent fins of the first plurality of fins;
• a first barrier extending outwardly from the outer surface of the main body;
• a first cavity defined at least by the first end portion of the main body, a first portion of the outer surface of the main body, the first plurality of fins, and the first barrier, wherein the first cavity is in fluid communication with the inlet port and the first number of microchannels;
• a second plurality of fins extending outwardly from the outer surface of the main body, defining a second number of microchannels between adjacent fins of the second plurality of fins;
• a second barrier extending outwardly from the outer surface of the main body;
• and
• a second cavity defined at least by the second plurality of fins, a second portion of the outer surface of the main body, and the second barrier,
• wherein the second cavity is in fluid communication with the second number of microchannels, and wherein the second plurality of fins includes the first plurality of fins.

A cooling system of a nugget-ice-making device, the cooling system comprising:

• a tubular outer body extending between a first outer body end portion and a second outer body end portion;
• a tubular inner body extending longitudinally between a first inner body end portion and a second inner body end portion, wherein the tubular inner body has a same perimetric shape as the tubular outer body but is perimetrically smaller than—and shares a common longitudinal axis with—the tubular outer body, such that a volumetric space is defined between an outward-facing surface of the tubular inner body and an inward-facing surface of the tubular outer body;
• a first plurality of fins attached—and forming a first plurality of fluid-communication barriers—between the outward-facing surface of the tubular inner body and the inward-facing surface of the tubular outer body, which barriers define a first number of microchannels between adjacent fins of the first plurality of fins, wherein a first end of each fin of the first plurality of fins is disposed at—and partially defines a first boundary of—a first cavity;
• an inlet port disposed nearer to the first outer body end portion of the tubular outer body than to the second outer body end portion, and providing a path of fluid communication with the first cavity;
• a second plurality of fins attached—and forming a second plurality of fluid-communication barriers—between the outward-facing surface of the tubular inner body and the inward-facing surface of the tubular outer body, which second plurality of fins defines a second number of microchannels between adjacent fins of the second plurality of fins, wherein a first end of a first subplurality of the second plurality of fins is disposed at—and partially defines the first boundary of—the first cavity, while a second end of a second subplurality of the second plurality of fins is disposed at—and partially defines a first boundary of—a second cavity, and wherein a first barrier disposed next to the first plurality of fins defines a second boundary of the first cavity;
• and
• a third plurality of fins attached—and forming a third plurality of fluid-communication barriers—between the outward-facing surface of the tubular inner body and the inward-facing surface of the tubular outer body, which third plurality of barriers defines a third number of microchannels between adjacent fins of the third plurality of fins,
• wherein a second end of a first subplurality of the third plurality of fins is disposed at—and partially defines a first boundary of—the second cavity, while a first end of a second subplurality of the third plurality of fins is disposed at—and partially defines a first boundary of—a third cavity, and wherein a second barrier disposed next to the second plurality of fins defines a second boundary of the second cavity, and
• wherein the first cavity is in direct fluid communication with the second cavity via the first number of microchannels, and is in indirect fluid communication with the third cavity further via the second number of microchannels.
