1. An electromagnetic field-functioning device for heating a fluid comprising:
- a) a magnetically inducible core and at least one electrical conductor that creates a magnetic field in the core when electrical current is conducted through the conductor and generates heat when in use;
b) a monolithic body of injection molded thermoplastic material substantially encapsulating the at least one conductor; and
c) a fluid pathway at least partially embedded in and integral with the monolithic body, with at least one fluid inlet and at least one fluid outlet to said pathway to allow for passage of fluid through the pathway, the outlet directing the fluid to a place of usage wherein heat picked up by the fluid as it transfers through the device is put to functional use.

Abstract
Electromagnetic components are provided with a heat exchange mechanism. For example, a fluid-cooled electromagnetic field-functioning device, such as a motor, generator, transformer, solenoid or relay, includes one or more electrical conductors. A monolithic body of phase change material substantially encapsulates the conductors or an inductor. At least one liquid-tight coolant channel is also substantially encapsulated within the body of phase change material. The coolant channel may be part of a heat pipe or cold plate. The coolant channel may be made by molding a conduit into the body, using a “lost wax” molding process, or injecting gas into the molten phase change material while it is in the mold. The coolant channel may also be formed at the juncture between the body and a cover over the body.
