Embodiment Construction

[0034] figure 1 A schematic illustration of the area of ​​the charge air cooler 1 is shown, which includes the charge air distribution box 2 and the charge air ducts 3 protruding from the charge air distribution box (the charge air ducts 3 are only shown as examples here). several in the air channel). Charge air is fed to charge air distribution box 2 via charge air lines 4 , the inflow direction of charge air being indicated by arrow 5 . The charge air line 4 opens into the charge air distribution box 2 at an opening 6 .

[0035] It is clear that the flow cross section widens downstream of the inlet opening 6 because the charge air channel 3 has a larger dimension in at least one direction as a whole than the charge air line 4 or the inlet opening 6 . Charge air line 4 is assigned to charge air inlet 7 of charge air cooler 1 . The charge air flowing into the charge air distribution box 2 enters the charge air channel 3 or at least a part of the charge air channel 3 and flo...

Abstract

A charge air cooler (1) for an internal combustion engine, includes a charge air inlet (7) and a charge air outlet which are fluidly connected with each other via multiple charge air channels (3) which are arranged parallel to each other and arranged parallel to each other and subjectable to a coolant flow; and at least one flow guide element (11) arranged upstream of the charge air channels (3), wherein the flow guide element at least in one operating state of the internal combustion engine deflects charge air entering through the charge air inlet (7) the direction of a condensate accumulation volume (10) of the charge air cooler (1). The invention further relates to a method for operating a charge air cooler.

Description

technical field [0001] The invention relates to a charge air cooler for an internal combustion engine, which has a charge air inlet and a charge air outlet which are connected via a plurality of flow-technically opposite Charge air channels arranged parallel to one another, preferably parallel to one another, through which the coolant can flow, are flow-connected to one another. The invention also relates to a method for operating a charge air cooler for an internal combustion engine. Background technique [0002] Such a charge air cooler is assigned to an internal combustion engine, which is used, for example, to drive a motor vehicle, ie to provide the torque intended to drive the motor vehicle. The internal combustion engine is pressurized. This means that the internal combustion engine is assigned a compressor which pressurizes the fresh gas supplied or to be supplied to the internal combustion engine upstream of the internal combustion engine, ie to a higher pressure ...
