A silencer for an internal combustion engine of a motor vehicle having a turbocharger and a charge air cooler is provided. The silencer includes a turbocharger module with a passage duct. An inlet interface is fastened to an outlet connector of the turbocharger of the internal combustion engine. An outlet interface of the turbocharger module is fastened one or more modules configured as a resonator module and/or a charge air cooler module. An outlet interface of the module most remote from the outlet connector of the turbocharger is fastened to an inlet interface of a feed line for the charge air cooler of the internal combustion engine.

A method for manufacturing a connection between a hose and coaxial line section is provided. The method includes providing an outer pipe, inserting an inner pipe along with a hose situated at least partially on an outer periphery of the inner pipe inside the outer pipe, and deforming the outer pipe, the inner pipe or both so that the hose becomes clamped between the inner pipe and outer pipe. A coaxial line section for a refrigerant circuit of a motor vehicle also is provided.

Solderless hose connection for a line section of an air conditioning system

A heat exchanger for a motor vehicle air-conditioning system includes: an outer tube, and an inner tube. The outer tube has a first path inlet and a first path outlet through which a first fluid is permitted to flow. The inner tube is disposed within the outer tube and has a second path inlet and a second path outlet through which a second fluid is permitted to flow. The inner tube branches off in a first region into at least two heat exchanger tubes.

Internal heat exchanger for a motor vehicle air-conditioning system

A connection device of a double-walled heat exchanger tube is provided, in particular for the heat exchanger of a motor vehicle air conditioning system. The heat exchanger tube has an outer tube and an inner tube that runs coaxially inside the outer tube spaced radially apart from it. The connection device further has a fitting for accommodating radially overlapping end sections of the inner and outer tube. The outer and inner tubes according to the invention are at least sectionally joined together without soldering in the area of the fitting, and with the fitting.

Connection device for a coaxial tube heat exchanger

A fastening device for fixing lines in the engine compartment of a motor vehicle, in particular lines for the air conditioner. Fastening recesses are provided in the engine compartment, on which the fastening device can be anchored. The fastening device has a clip base for this purpose. A clip head is used for fastening the fastening device to the line. At least one of the fastening clips is situated so it is longitudinally movable on the compensating rail, so that the fastening device can be adapted to the installation situation.
