본 발명은 중공 샤프트 배열체 (1) 에 관한 것으로, 상기 중공 샤프트 배열체 (1) 는, 냉각 목적을 위해 유체가 통과할 수 있는 중공 샤프트 (2), 특히 전동 모터의 로터 샤프트를 포함하고, 상기 중공 샤프트 (2) 의 내부 공간 (3) 내에는, 상기 중공 샤프트 (2) 로부터의 열 에너지를 상기 유체에 전달하기 위한 표면-확대된 냉각 구조들 (9) 이 배열된다. 상기 냉각 구조들 (9) 은 상기 중공 샤프트 (2) 에 연결되고, 상기 냉각 구조들 (9) 은 상기 중공 샤프트 (2) 로부터 별개로 형성되는 냉각 보디 (8) 의 일부이다.

    A hollow shaft arrangement may include a hollow shaft, such as a rotor shaft of an electric motor, for example, through which a fluid can pass for cooling purposes. Surface-enlarging cooling structures for transferring thermal energy from the hollow shaft to the fluid may be arranged in an inner space of the hollow shaft. The surface-enlarging cooling structures may be connected to the hollow shaft, but may be part of a cooling body that is formed separately from the hollow shaft. Further, the cooling body may include a sleeve-like main body from which the surface-enlarging cooling structures project radially inwardly, and the sleeve-like main body may include an axial gap that permits a circumference of the main body to be adjustable. In some cases an outer diameter of the cooling body is larger than an inner diameter of the bearing.
