ORIENTATION CONTROL DEVICE FOR MAGNETIC FLUID AND METHOD FOR SAME

WIPO Patent Application WO/2013/165105

A8

Provided is an orientation control device for a magnetic fluid that comprises: a magnetic fluid which has magnetic nanoparticles; a silicone tube through which the magnetic fluid passes; an induction power generation unit which has a solenoid coil wound over a predetermined section outside the silicone tube so that induced power is generated when the magnetic fluid passes through an inner side of the silicone tube; and a magnetic pole direction control unit which has a solenoid coil which is wound over a predetermined section in the silicone tube and outside the silicone tube at an entrance portion of the induction power generation unit so that a flux is generated when an electric current flows and the pole orientation of the magnetic fluid can be controlled, and a method for same. According to the orientation control device for a magnetic fluid and the method for same of the present invention, in a system in which a fluid having magnetism (magnetic fluid) instead of an existing cycle refrigerant is directly circulated in a heat conversion cycle and used for direct conversion into electricity by using an induction coil, magnetic particles forming the magnetic fluid are applied through a polarity or orientation control method so as to maximize the amount of electromotive force generated in the induction coil and generate electricity efficiently.
