Abstract

The present invention relates to a device for cooling charge air for an internal combustion engine of a vehicle. The device comprises a plurality of first coolant pipes for conducting a first coolant and a plurality of second coolant pipes for conducting a second coolant, wherein the first coolant pipes and the second coolant pipes extend in a longitudinal extension direction of the device and the plurality of first coolant pipes is arranged adjacent to the plurality of second coolant pipes in a transverse extension direction of the device.

First claim

The invention claimed is:

1. An intake module for supplying an internal combustion engine of a vehicle with compressed and cooled charge air, wherein the intake module comprises the following features:
a housing for conducting the charge air from a compressor of the vehicle to the internal combustion engine of the vehicle, wherein the housing forms a flow channel for the charge air and has an opening for receiving a device for cooling charge air for an internal combustion engine of a vehicle; and
a device for cooling charge air for an internal combustion engine of a vehicle wherein the device comprises the following features:
a plurality of first coolant pipes for conducting a first coolant;
a plurality of second coolant pipes for conducting a second coolant, wherein the first coolant pipes and the second coolant pipes extend along a longitudinal extension direction of the device and the plurality of first coolant pipes is arranged adjacent to the plurality of second coolant pipes in a transverse extension direction of the device;
a first base and an associated tank which surrounds an end region of the plurality of first coolant pipes and of the plurality of second coolant pipes, and
a second base and associated tank which surrounds a further end region opposite the end region of the plurality of first coolant pipes and of the plurality of second coolant pipes;
wherein the tanks have separators that prevents mixing of the first coolant and second coolant,
wherein the device is received by the opening in the housing such that the plurality of first coolant pipes and the plurality of second coolant pipes are arranged transverse to the flow channel for the charge air, such that the plurality of first coolant pipes is located upstream in the flow channel and the plurality of second coolant pipes is located downstream in the flow channel,
wherein the first base has a flange which extends at least partly around a periphery of the device, wherein the flange mounts the device to the housing and seals the flow channel within the intake module against the outside of the intake module.

2. The intake module as claimed in claim 1 , wherein the first tank has a first inlet connection or outlet connection for the inlet or outlet of the first coolant into/out of the plurality of first coolant pipes, and a second inlet connection for the inlet of the second coolant into the plurality of second coolant pipes.

3. The intake module as claimed in claim 1 , wherein the second tank furthermore comprises a first outlet or inlet connection for the outlet or inlet of the first coolant from the plurality of first coolant pipes and/or the first tank comprises a second outlet connection for the outlet of the second coolant from the plurality of second coolant pipes.

4. The intake module as claimed in claim 1 , wherein the plurality of first coolant pipes and/or the plurality of second coolant pipes are connected using separators in the tanks such that for the first and/or the second coolant, an I-flow or a U-flow through the device is achieved.

5. The intake module as claimed in claim 4 , wherein the plurality of first coolant pipes are connected such that an I-flow through the device is achieved.

6. The intake module as claimed in claim 1 , wherein the tanks for the first coolant and second coolant respectively are formed separated.

7. The intake module as claimed in claim 1 , in which the plurality of first coolant pipes and/or the plurality of second coolant pipes are present as u-shaped bent pipes.

8. The intake module as claimed in claim 1 , wherein the device furthermore comprises a plurality of ribs for conducting the charge air, wherein each rib of the plurality of ribs is arranged between a layer of coolant pipes of the plurality of first coolant pipes and an adjacent layer, in the transverse extension direction of the device, of the plurality of second coolant pipes.

9. A system for conditioning charge air for an internal combustion engine of a vehicle, wherein the system comprises the following features:
an intake module for supplying an internal combustion engine of a vehicle with compressed and cooled charge air as claimed in claim 1 ;
a high-temperature coolant circuit for conducting the first coolant, which has a high temperature, wherein the high-temperature coolant circuit is connected with the plurality of first coolant pipes; and
a low-temperature coolant circuit for conducting the second coolant, which has a low temperature, wherein the low-temperature coolant circuit is connected with the plurality of second coolant pipes.

10. The intake module as claimed in claim 1 , wherein flange comprises a stop device that limits the insertion of the device in the housing such that the device is positioned in the housing of the intake module in the correct position.
