Abstract: A fresh air supply device for an internal combustion engine may include a suction module for conducting supercharged fresh air and a charge air cooler arranged in the suction module for cooling the supercharged fresh air. The suction module includes a housing with a charge air inlet for uncooled charge air and a charge air outlet for cooled charge air. The housing has a cooler shell, which may include the charge air inlet containing the charge air cooler and an assembly opening. With respect to a flow direction of the charge air the assembly opening may be arranged downstream of the charge air cooler and through which the charge air cooler is inserted into the cooler shell. The housing has a connecting shell, which includes the charge air outlet and which in the region of the assembly opening is attached to the cooler shell in an air-tight manner.

Abstract: A tube (10) for an exhaust gas cooler comprises at least two projections (14), developed on the inside, of which at least one, implemented closer to the gas inlet, is developed lower in the direction toward the tube axis than at least one that is implemented closer to the gas outlet. An exhaust gas cooler comprises at least one such tube.

Abstract: A heat exchanger is disclosed for the exhaust gas train of a motor vehicle with an exhaust gas carrying exchanger tube that is formed separately and is disposed in a closed housing formed separately, a coolant flowing through the housing and around the outer side of the exchanger tube. The housing forms at least one housing cover and one housing case, the housing case being tightly closed by the housing cover. Both ends of the exchanger tube are conducted for gas and liquid tight connection through the housing cover so that the inlet and the outlet of the exchanger tube are disposed outside of the housing.

Abstract: An electric actuator (32) for a clutch arrangement (26, 28, 52) of a motor vehicle (10) has an electric drive unit (40) for providing mechanical driving force, an electric control unit (38) that is connected to the electric drive unit (40) to control the drive unit (40), and a cooling element (42) that is connected thermally to electric components of the drive unit (40) and/or the control unit (38). The cooling element (42) is assigned a coolant line (44), through which a coolant can be conducted to dissipate heat from the electric components.

Abstract: A charge-air cooling device for a fresh air system of an internal combustion engine may include a housing which contains a charge-air duct and a heat exchanger having an internal coolant path and an external charge-air path. The housing may have a mounting opening, through which the heat exchanger is pushed into the housing in a longitudinal direction of the heat exchanger such that, in a pushed-in state, the charge-air duct leads through the charge-air path. The housing may include at least one wall in a receiving region which receives the heat exchanger. The wall may be elastic and, by the heat exchanger being pushed into the receiving region, the wall may be transferred from a relaxed state when the heat exchanger has not been pushed into the receiving region, into a stressed state when the heat exchanger has been pushed into the receiving region.
