Induction coils and induction coil cooling methods

Abstract

The invention relates to an induction coil, comprising a first component (12); a second component (14); a conductor length (18); a heat sink (100); in which the first component is placed adjacent to the second component; in which the core (16) is formed from the first and second components; in which the first part of the conductor length is wound at least around the core to form several turns of the conductor; in which the heat sink comprises a heat-conducting material; In which, the heat sink comprises a first part (90, 110) and a second part; in which, the first part of the heat sink has the first material and / or structural characteristics and the second part of the heat sink has the second material and / or structural characteristics different from the first material and / or structural characteristics; and in which, the inner surface of the first part of the heat sink is in contact with the outer surface of a portion of several turns of the conductor. The invention also describes a method for cooling the induction coil.
