Abstract

The invention relates to a cooling device (1,2) pertaining to an electrical machine (10), said cooling device (1,2) comprising at least one rod-shaped heat-conducting means (3,4) for heat-conductive connection to the electrical machine (10). The invention also relates to an electrical machine (10) comprising a housing (18) and / or a stator (14), said housing (18) and / or stator (14) being applied to a cooling device (1,2) comprising a rod-shaped heat-conducting means (3,4) extending axially in relation to the electrical machine. Said heat-conducting means (3,4) is to be received by the stator (14) and / or the housing (18) or arranged on the stator (14) and / or the housing (18).

Description

technical field [0001] The invention relates to a cooling device for an electric machine and the electric machine itself, and to a cooling system for an electric machine. Background technique [0002] During operation, the electric motor generates heat loss, which can be dissipated via a corresponding cooling system or a corresponding cooling device. For example, cooling systems or cooling devices operating with cooling air, cooling water or heat pipes can be used to cool the electric machine. Such a cooling system or cooling device is integrated in the electric machine, wherein each electric machine has a cooling device specially designed for it. [0003] An air-cooled electric machine is disclosed, for example, in DE 4242132. A disadvantage of such an electric machine is that its cooling device does not work in accordance with the thermal load to which the electric machine is exposed at the site of use. The thermal load of the electric machine depends, for example, on t...
