Title:
WINDING COMPONENT
Document Type and Number:
WIPO Patent Application WO/2015/111404
Kind Code:
A1
Abstract:
Provided is a winding member capable of: reducing the core temperature in comparison to conventional winding members, even for applications having a large amount of core heat generation; and, as a result, of being more compact and lighter weight. The present invention has a coil (2) and a pair of upper/lower cores (4, 5) surrounding the outer perimeter of this coil (2) and forming a closed magnetic circuit. A metal plate (7) having a higher thermal conductivity than the lower core (5) is attached to an outer surface (6) of the lower core (5), in a winding component mounted in a case (1) wherein the bottom surface of the lower core (5) has a heat-dissipating function.
