Cooling of a bobbin assembly for an electrical component

摘要

A cooling system is provided for electrical components in which cooling assemblies (11, 45) are inserted in non-magnetic cores of the electrical components, and in which tubes provide both inflow and outflow of a cooling medium. The non-magnetic cores may be bobbins (30) for an inductor assembly or the core of a capacitor (40). The tubes may form a loop (11) in more than one plane to prevent inducing current in a single turn, or they may be split-flow closed-end tubes (45) inserted from one end of the electrical component. The bobbin cores (31) are also constructed with a non-conductive portion to prevent inducing a current in a single turn of a conductor.
