| 摘要 |
The invention relates to a cooling device (26) for cooling a component (14) of an electrical machine (10), for example a stator of an electric motor. The cooling device (26) comprises a combination of at least two phase change materials (PCMs) which have a reversible, thermally inducible, endothermic phase transition at a phase transition temperature (Ttr), a first phase transition temperature (Ttr1) of a first phase change material (28) being within a non-critical operating temperature range of the component to be cooled (14) and a second phase transition temperature (Ttr2) of a second phase change material (30) being above the first phase transition temperature (Ttr1). |
