Housing casing for cooling electrical motor, has housing casing segments including outer surface with flat contact surface, where lid lies at contact surface, and casing includes region with polygon outer surface in cross-section

摘要

The casing (1) has multiple housing casing segments (4) including an outer surface (6) with a flat contact surface (7), where a rectangular lid lies at the contact surface. The lid covers the contact surface. The casing includes a region with a polygon outer surface (9) in a cross-section. Recesses (10) for coolant i.e. liquid coolant, are formed in outer surface segments and include radially extending side walls (11, 12). Coolant channels are milled at the outer surfaces. The recesses are flow technically connected with each other. The casing is divided between the outer surface segments.
