Thermal management system for smc inductors

An inductor comprising:

• a coil;
• and
• a core;
• wherein the core is made of a Soft Magnetic Composite (SMC);
• wherein the coil is an annularly wound electrical wire;
• wherein the coil integrated into the core so that the core material acts as a thermal conductor having thermal conductivity above 1.5 W/m*K, conducting heat from the coil;
• wherein the inductor is in thermal connection with at least one thermal connecting fixture;
• wherein the at least one thermal connecting fixture is adapted to be connected to a first external heat receiver so as to conduct heat from the inductor to the first external heat receiver;
• and
• wherein the core has at least one integrated cooling pipe in thermal connection with the coil, and the at least one cooling pipe being adapted to accommodate a flow of a fluid for transporting heat from the coil.
