A climate control system including a heat exchanger assembly with a housing having an external air inlet, an external air outlet, an internal air inlet, and an internal air outlet. The system further includes an auxiliary air vent assembly coupled to the heat exchanger assembly. The auxiliary air vent assembly includes a rim at least partially defining an internal air inlet region and an internal air outlet region.

A shaping method for a double pipe includes: bending the double pipe with a specified curvature to form a bent portion in the double pipe; and arranging the bent portion on a first shaping die having a first shaping surface at a position biased inward or outward in a curvature radius direction of the bent portion relative to the first shaping surface, wherein the first shaping surface is configured to shape a first outer surface of both outer surfaces of the bent portion that are located on both sides of a plane including a central axis of the bent portion, and pressing the bent portion arranged on the first shaping die by a second shaping die having a second shaping surface configured to shape a second outer surface of the both outer surfaces of the bent portion.

A coil banding device includes a tubular nozzle penetrating the central portion of the housing, the material coil being supplied therethrough, a nozzle moving member to move the nozzle, a banding member including a pair of roller members on an upper surface of the rotating member and sandwiching the material coil discharged from the nozzle to band in a set shape, a horizontal moving member for moving the banding member horizontally through a first plate slidably mounted to the housing, a vertical moving member for moving the banding member vertically through a second plate slidably mounted on the first plate, a first rotating member for rotating the banding means with respect to a horizontal axis through a third plate rotatably mounted on the second plate, and a second rotating member for rotating the banding member about a vertical axis by a planetary gear mounted on the second plate.

A method of forming an annular part includes forming a conical or frusto-conical preform with at least one open end, initiating an actuation means to cause relative coaxial movement only between a punch, a clamping means and a gripping means, thereby clamping a large diameter end of the preform in the clamping means and gripping a second small diameter end of the preform in the gripping means and the external surface of the punch to engage the internal surface of the preform, and causing relative co-axial movement between the gripping means and the punch so that the portion of the wall of the preform between the punch and the gripping means is formed over the leading edge of the punch.

A method of fabricating a fluid component body includes forming a monolithic fluid component body including a valve segment having an annular upper perimeter wall portion defining a valve cavity and a lower base portion defining first and second flow ports, and a conduit segment extending from one of the first and second flow ports and including a conduit end portion defining a tubular portion extending in a first direction and spaced apart from a remainder of the fluid component body. The conduit end portion is bent from the first direct to a second direction.
