Abstract
Examples are disclosed herein that relate to a heat removal system utilizing a dispersion that includes particles of an electrical conductor. One example provides a heat removal system including a conduit loop, a dispersion of particles of an electrical conductor in a heat transfer fluid, a pair of electrodes configured to introduce a flow of electric current through the particles in the dispersion, and one or more magnets configured to introduce a magnetic field within the conduit loop in a region of the pair of electrodes, such that the electrodes are operable to apply an electromagnetic pumping force on the particles in the dispersion.

A heat removal system, comprising:
- a conduit loop;
- a dispersion of anisotropically conductive graphene-based flakes in a heat transfer fluid disposed within the conduit loop;
- a pair of electrodes to apply an electric field across the conduit loop and thereby align the graphene-based flakes in the dispersion via the electric field, and to introduce a flow of electric current through the graphene-based flakes in the dispersion;
- and
- one or more magnets to introduce a magnetic field within the conduit loop in a region of the pair of electrodes, such that the electrodes are operable to apply an electromagnetic pumping force on the graphene-based flakes in the dispersion to push the heat transfer fluid within the conduit loop via the graphene-based flakes as aligned by the electric field.
