Abstract (en)
[origin: WO2021115895A1] Stator housing (2) for an electrical machine (1), comprising an inlet (9) for a cooling fluid, an outlet (10) for the cooling fluid, a cooling duct (11) which is formed between the inlet (9) and the outlet (10) and through which the cooling fluid can flow in a direction of flow directed from the inlet (9) to the outlet (10), wherein the cooling duct (11) has a first heat transfer arrangement (12) and a second heat transfer arrangement (13) which each extend along the direction of flow and are designed to transfer heat from the cooling fluid to the stator housing (2), wherein the first heat transfer arrangement (12) is arranged in a first section (16) of the cooling duct (11) and the second heat transfer arrangement (13) is arranged in a second section (17) of the cooling duct (11) that is on the inlet side with respect to the first section (16), wherein the first heat transfer arrangement (12) in the first section (16) creates a larger heat transfer area for the cooling fluid per unit of length based on the direction of flow than the second heat transfer arrangement (13) in the second section (17).
