Abstract

A heat transfer unit for an internal combustion engine includes a first channel with an inlet and an outlet. The first channel is configured to have a fluid to be cooled flow therethrough. The second channel is configured to have a cooling fluid flow therethrough. A partition wall(s) is disposed to separate the first channel from the second channel. Ribs extend from partition wall(s) into the first channel and are disposed in a principal flow direction of the fluid to be cooled. The second channel comprises a first section and a second section in the principal flow direction. The ribs of the first section have a first cross section in a first flow-off portion that is constant in the principal flow direction. The ribs of the second section have a second cross section in a second flow-off portion that widens in the principal flow direction.
