Abstract
Stator housing for an electrical machine having an inlet and outlet for a cooling fluid, and a cooling duct formed between the inlet and the outlet through which the cooling fluid flows in a direction from the inlet to the outlet, is disclosed. The cooling duct has a first and a second heat transfer arrangement, which each extend along the direction of flow and are designed to transfer heat from the cooling fluid to the stator housing. The first heat transfer arrangement is arranged in a first section of the cooling duct and the second is arranged in a second section that is on the inlet side with respect to the first section. The first heat transfer arrangement in the first section creates a larger heat transfer area for the cooling fluid per unit of length based on the direction of flow than the second in the second section.
