ferro uid. We denote this heat exchanger as HHEX (hot heat exchanger). Another

pair of cross-

fl

fl ow micro heat exchangers is connected to the heat source (not shown

in the gure). They also comprise water fl uid channels and voids, which contain the

ferro uid. We denote this heat exchanger as CHEX (cold heat exchanger).

A magnet assembly rotates as the pendulum in each direction. The maximum angle
(azimuth path) that the magnet assembly performs in one direction is 90

fl

. Since the

°

ferro fl uid is incompressible, as well as responding to the magnetic eld (magnetic

fl uid), each movement of the magnet assembly will pull as well as push the fer-

ro fl uid through the voids in the AMRs, as well as the heat exchangers. In the case of
