Fluid pipe arrangement

A fluid pipe arrangement for a charged air duct of an internal combustion engine, comprising:

• a housing elongated in a direction of a longitudinal axis (L) extending through an interior of the housing, the housing including:
• a first housing part having
• a circumferential radially outer wall extending circumferentially about the longitudinal axis (L) and surrounding the interior of the housing;
• and
• an end wall of the first housing part affixed onto a second axial end of the circumferential radially outer wall, closing over the interior;
• a second housing part forming a cover fixed onto a first axial end of the circumferential radially outer wall of the first housing part;
• a first fluid duct formed at least partially by the circumferential radially outer wall and the end wall of the first housing part, the first fluid duct having:
• a first fluid inlet formed on and opening through the circumferential radially outer wall of the first housing part into the interior;
• a first fluid outlet for a first fluid formed on and opening though an axially outer face of the second housing part,
• wherein the first fluid inlet is in fluid communication with the first fluid outlet through the first fluid duct;
• at least one second fluid duct extending axially through the interior of the housing and radially surrounded by the first fluid duct, the at least one second fluid duct having:
• a second fluid inlet arranged on and extending axially though the axially outer face of the second housing part;
• a second fluid outlet extending through the end wall of the first housing part,
• wherein the second fluid inlet is in fluid communication with the second fluid outlet through the at least one second fluid duct;
• a secondary pipe extending axially in the interior and spaced radially outwardly away from and radially surrounding the at least one second fluid duct, the radial spacing forming a gap between the secondary pipe and the at least one second fluid duct,
• wherein the radial spacing of the gap provides thermal insulation between at least a portion of the second fluid duct and at least a portion of the first fluid duct.
