Abstract: A heat exchanger comprises a seamless body, and the seamless body may include a substantially cylindrical configuration defining a radial direction, a circumferential direction, a longitudinal axis, a first cylindrical wall and a plurality of fins. Each fin may extend at least partially in the radial direction and helically along the longitudinal axis. Also, each fin may be at least partially hollow defining an internal flow passage, and each fin of the plurality of fins may be at least partially spaced away from an adjacent fin, defining an external flow passage.

Abstract: A snap ring assembly is provided. The snap ring assembly includes a base set. The base set includes a first base section and a second base section. The first base section is adapted to be disposed adjacent and substantially coplanar with respect to the second base section. The snap ring assembly also includes a retaining set. The retaining set includes a first retaining section and a second retaining section. The first retaining section is adapted to be disposed adjacent and substantially coplanar with respect to the second retaining section. Each of the first retaining section and the second retaining section is adapted to be removably coupled to each of the first base section and the second base section.
