    • Magnetic fluid cooling devices and power electronic devices are disclosed. In one embodiment, a magnetic fluid cooling device includes a magnetic field generating device, a magnetic fluid chamber assembly, and a heat sink device. The magnetic field generating device includes a plurality of magnetic regions having alternating magnetic directions such that magnetic flux generated by the magnetic field generating device is enhanced on a first side of the magnetic field generating device and inhibited on a second side of the magnetic field generating device. The magnetic fluid chamber assembly defines a magnetic fluid chamber configured to receive magnetic fluid. The heat sink device includes a plurality of extending fins, and is thermally coupled to the magnetic fluid chamber assembly. Power electronic devices are also disclosed, wherein the magnetic fluid chamber may be configured as opened or closed.
    • 公开了磁流体冷却装置和功率电子装置。 在一个实施例中,磁流体冷却装置包括磁场产生装置,磁性流体室组件和散热装置。 磁场产生装置包括具有交变磁方向的多个磁区,使得由磁场产生装置产生的磁通在磁场产生装置的第一侧被增强,并且在磁场产生装置的第二侧被禁止 。 磁性流体室组件限定了构造成接收磁性流体的磁性流体室。 散热装置包括多个延伸翅片,并且热耦合到磁性流体室组件。 还公开了电力电子设备,其中磁性流体室可以被配置为打开或关闭。
