1. An electric motor (EM) system with integrated heat exchanger, comprising:
a housing comprising:
a cylindrical shape with a longitudinal extension according to an axial direction;
surface area increasing features that protrude outward of the cylindrical shape of the housing; and
a first group of channel segments for provision of an embedded housing oscillating heat pipe (OHP), the first group of channel segments extending axially and circumferentially within the cylindrical shape of the housing and into the surface area increasing features; and
a core structure of a stator coupled along a region of the longitudinal extension of the housing,
wherein
the core structure comprises a second group of channel segments for provision of an embedded core OHP,
the first group of channel segments form a first continuous channel inside of the housing for provision of the housing OHP,
the second group of channel segments form a second continuous channel inside of the core structure for provision of the core OHP, and
the housing with the first group of channel segments and the core structure with the second group of channel segments form one monolithic structure.
