Abstract
An electromagnetic, liquid or gas cooled solenoid coil is constructed of an inner core formed by a simulated pole piece. The inner core has coolant feed ports that communicate with a surrounding perforated bobbin. A pair of ordinary electromagnetic wires is twisted around each other to form a helix, and the helix is wrapped around the perforated bobbin. Liquid or gas coolant is introduced into an opening in the core, flows through the ports into the bobbin, and then flows radially through the coil from the inside diameter of the coil to the outside diameter of the coil, thereby removing heat from the self-heating coil wire. In alternative embodiments, a supply manifold and receiver manifold are integrated into the solenoid coil.
