    • The invention relates to a centrifuge (10) having a safety vessel (30) with a vessel wall (32), a rotor (17), which is arranged in the safety vessel (30) and is connected via a drive shaft (20) to a drive device (22), wherein at least the drive shaft (20) extends through the safety vessel (30), a cooling system for cooling an interior space (31) of the safety vessel (30), which comprises a heat transfer medium (19) for taking up heat from the safety vessel (30), a refrigerating unit (12) and conducting means (18) for the heat transfer medium (19). The invention is distinguished by the fact that the refrigerating unit (12) is based on the magnetocaloric effect, and the interior space (31) of the safety vessel (30) is cooled by a first cooling circuit (111), the magnetocaloric effect of the refrigerating unit (12) extracts heat from the heat transfer medium (19) of the first cooling circuit (111) and feeds the heat to a second cooling circuit (113).
    • 本发明涉及一种具有带有容器壁(32)的安全容器(30),布置在安全容器(30)中并通过驱动轴(20)连接的转子(17)的离心机(10) 其中至少所述驱动轴(20)延伸穿过所述安全容器(30)的驱动装置(22),用于冷却所述安全容器(30)的内​​部空间(31)的冷却系统,所述冷却系统包括热传递 用于从安全容器(30)吸收热量的介质(19),制冷单元(12)和用于传热介质(19)的传导装置(18)。 本发明的特征在于,制冷单元(12)基于磁热效应,并且安全容器(30)的内​​部空间(31)由第一冷却回路(111)冷却,因此磁热效应 制冷单元12从第一冷却回路111的传热介质19中提取热量并将该热量输送到第二冷却回路113。
