Abstract
A coolable machine housing of an electric machine has a housing shell formed as an extruded section with integrated cooling ducts. The housing shell can be covered at the end faces by bearing end plates. The axially extending cooling ducts communicate with one another through connecting ducts. The cooling ducts in the extruded housing shell extend in pairs as cooling duct pairs between the shell end faces. The connecting ducts are boreholes that penetrate the outer wall by way of borehole openings that are closed by way of closing elements.
