1. A device for cooling components, the device comprising:
a main body; and
cylindrical and/or conical cooling fins, wherein the cooling fins are positioned in the main body,
wherein a coolant is configured to flow around the cooling fins in a flow direction,
wherein the cooling fins are positioned in parallel first rows and equally spaced apart from one another,
wherein each first row of the parallel first rows is arranged along a row direction that is different from the flow direction, and
wherein adjacent first rows of the parallel first rows are arranged offset with respect to one another in the row direction such that, for each cooling fin in the parallel first rows, an axis of a respective first cooling fin in one first row is offset by at least 25% of a hydraulic diameter from an axis of a respective second cooling fin in an adjacent first row such that the respective first and second cooling fins are situated in series in the flow direction and are offset transversely to the flow direction and are not parallel with the flow direction such that no rows of cooling fins are formed in alignment with the flow direction.
