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.

Fresh air supply device of an international combustion engine

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.

Charge-air cooling device

A heat exchanger assembly may include an intercooler and a housing which encloses said intercooler. The housing may be part of a charge air line. The housing may include a charge air inlet, a charge air outlet and an opening through which the intercooler can be inserted into the housing from one side. The housing may also include a recess on the side opposite the opening, into which recess the intercooler engages. The heat exchanger assembly may include an elastic seal arranged in the region of the recess between the intercooler and the housing. The seal may be configured to at least one of bridge the deformation of the housing occurring during pressure pulsations, bridge relative movements between the intercooler and the housing, and tightly connect the intercooler to the housing in all operating states preventing an undesirable bypass flow.

Heat exchanger assembly

A heat exchanger for transferring heat between a gaseous first fluid and a liquid second fluid may include a plurality of hollow pipes extending transversely through a first fluid path for conducting the first fluid. The plurality of pipes may be coupled externally to a plurality of cooling fins arranged in the first fluid path. The plurality of pipes may internally define a second fluid path for conducting the second fluid. The plurality of pipes and the plurality of cooling fins may be arranged stacked on one another in a stacking direction to define a cooler block. The cooler block may include two side parts extending along two outer sides of the cooler block facing away from one another in the stacking direction. At least one tension rod may fixedly connect the two side parts and be configured to transmit a tensile force in the stacking direction.

Heat exchanger

A method for producing an intake module may include providing a housing and at least one intercooler arranged therein; forming at least two housing parts via injection molding from plastic; inserting at least one intercooler into at least one of the housing parts; wherein the housing parts, with at least one intercooler inserted therein, are welded together to form the housing; and wherein the intercooler has contact points to at least two of the housing parts.

Component and associated production method

The invention relates to an intake pipe for an internal combustion engine of a motor vehicle, comprising a housing that defines a charge-air channel and an intercooler having a cooler block, which is arranged in the housing in such a way that the charge air can flow through the cooler block. The cooler block of the intercooler terminates on a side facing the housing with an outer component, preferably a cooling fin, and at least one recess is formed in said outer component of the cooler block, the at least one recess extending at least across part of the length of the cooler block substantially perpendicularly to the charge-air flow direction. Furthermore, at least one projection is provided on an inside face of the housing facing the cooler block of the intercooler, said projection extending at least across part of the inner face of the housing substantially perpendicularly to the charge-air flow direction and engaging at least partially in the at least one recess of the cooler block in a sealing manner.

Intake pipe having an integrated intercooler

An integrated exhaust gas recirculation intake module comprises: an intake system including a fresh air channel; and a coupling device, wherein the coupling device is configured to receive an exhaust gas recirculation valve, wherein the coupling device is configured to connect an exhaust gas channel with a fresh gas channel, and wherein the exhaust gas channel is connected with the coupling device such that a heat transfer is hindered.
