Abstract
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.
