1. A thermal control system including an electrohydrodynamical (EHD) pumping device, comprising:
a closed loop arranged to carry a circulating dielectric fluid;
at least a first heat exchanger in the closed loop; and
a flow unit in the closed loop comprising:
a first electrode; and
a second electrode offset from the first electrode in a downstream direction of a flow of the circulating dielectric fluid, the first electrode and the second electrode being connectable to a voltage source and configured to provide an electric field to ionize particles or molecules and control a flow of the circulating dielectric fluid;
wherein the first electrode is formed as a grid structure and arranged to allow the circulating dielectric fluid to flow through the first electrode, and
wherein the first heat exchanger is separate from the grid structure.
