Title:
MAGNETIC FLUID DRIVE DEVICE AND HEAT TRANSPORT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/208888
Kind Code:
A1
Abstract:
A magnetic fluid drive device (10) drives, in accordance with received heat, a magnetic fluid (40) that has temperature sensitivity. The magnetic fluid drive device comprises a heat receiver (21), and magnetic members (31, 32). The heat receiver includes a flow passage (20) through which the magnetic fluid flows, and receives heat. The magnetic members include at least one magnet, and generate a magnetic field between a pair of opposing surfaces (31a, 32a). The heat receiver has a size that is larger in a width direction (X), which crosses a flow direction (Z) in which the magnetic fluid flows in the flow passage, than in a vertical direction (Y), which crosses the flow direction and the width direction. The magnetic members are disposed so that the pair of opposing surfaces are positioned on both width-direction sides of the heat receiver and face each other via the heat receiver.
