Abstract
A cooling structure for a rotary electric machine, the structure includes an annular radiator body defining an axis X between a first end and a second end, the annular body having a radially inner wall and a radially outer wall and a plurality of channels defined between the radially inner wall and the radially outer wall. Each channels extends from the first end to the second end, each channel having a radially varying profile along the length of the channel to interrupt the linear flow of fluid along the channel and to cause continuous changes in flow direction as the fluid flows from one end of the channel to the other.
