Internal oil fins before assembly and inside a cut-open brazed core.

This fin structure sits inside the oil passage. The photograph shows the internal component while it is exposed during manufacturing.
In the finished brazed cooler, this structure is enclosed inside the oil channel and cannot be seen from the outside.

This photograph shows an actual oil cooler core that has been cut open. The fin structure at the center of each narrow channel is the oil passage fin.
These internal fins are enclosed inside the oil passages after brazing. The cutaway reveals the structure that cannot be seen from outside an intact finished cooler.
