Motor Housing Cooling Flow Path Design

The cooling flow path is segmented into multiple sections: a first cooling flow path extending in the circumferential direction, a second cooling flow path extending in the axial direction, and a connection flow path connecting them. This segmentation allows the coolant to flow through different regions systematically, improving cooling efficiency for both the stator and inverter while maintaining a manageable structural complexity through modular flow path design.

The cooling flow path transitions from a two-dimensional planar arrangement to a three-dimensional configuration by adding the axial direction component. The first cooling flow path extends circumferentially while the second cooling flow path extends axially, creating a spatial network that covers multiple dimensions. This dimensional expansion enables more comprehensive heat dissipation without significantly increasing structural complexity.

Multiple cooling flow paths (first cooling flow path extending circumferentially, second cooling flow path extending axially, and connection flow path) are merged into a single integrated cooling system within the housing. The connection flow path seamlessly links the different directional segments, creating a unified coolant circulation network that improves cooling efficiency without requiring separate independent cooling systems, thus avoiding excessive complexity.

The cooling flow path system serves multiple functions simultaneously: it cools the stator through one segment, cools the inverter through another segment, and provides structural integration within the housing. The single cooling system performs multiple cooling tasks that would otherwise require separate systems, reducing overall device complexity while maintaining high cooling efficiency.
