Abstract

A machine housing having one wall with an outer side provided with ribs for the discharge of heat to the surrounding air. The ribs define undulation crests and there are curved undulation bases between the undulation crests. The ratio between the wall thickness and the rib height and the ratio between the rib pitch or spacing of the wall thickness and the radius of curvature of the undulations as compared with the wall thickness are all recited. The ribs preferably are parallel and preferably extend vertically in the installed position of the machine housing.
