Abstract
A cooling assembly to be inserted in electric machines includes a generally cylindrical body to be inserted inside the internal stator of an electric machine. The body includes a top surface provided with angled bores forming V-shaped channels inside the body. Intersecting V-shaped channels are closed by plugs to thereby define a continuous cooling channel inside the body.
