However, in practical application, the nanoparticles have small particle size, large specific surface area and small volume fraction, so that the nanoparticles are easy to agglomerate and settle when dispersed in a base liquid. And because the size of the magnetic nano particles is very small, the magnetic nano particles can often enter the rough part of the wall surface of the flow channel, the transmissivity of the wall surface of the fluid can be reduced when nano magnetofluid is used for heat collection or photovoltaic frequency division, and the fluid is heated unevenly. Therefore, how to make the nano-magnetic fluid particles uniformly and stably dispersed in the base liquid in the flowing process is always the key in the using process of the nano-magnetic fluid.
The electromagnetic control is applied to the nano-magnetic fluid, so that the nano-magnetic fluid can form magnetic chains in a specific direction in the flowing process of the nano-magnetic fluid, and the directional magnetic field is applied to the area with low flow velocity and possible precipitation, so that the magnetic nano-particles can better move along the preset direction. In addition, the electromagnetic descaling device can perform electromagnetic descaling on the fluid channel after use, so that nanoparticles attached to the rough surface of the fluid channel are cleaned to the maximum extent, and the service life of the fluid channel is prolonged.
