Document Type and Number:
WIPO Patent Application WO/2019/176686
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a reactor in which heat dissipation properties of a core are high and eddy-current loss of a coil is low. The reactor (1) according to the present invention is provided with: a plurality of divided cores (10) that are made of a soft magnetic material and are formed in a shape such that an annular core is divided in the circumferential direction; a core gap member (20) that is made of a non-magnetic material and is disposed between the plurality of divided cores (10) in the annular core, which is formed by combining the plurality of divided cores (10); an annular heat-dissipating case (30, 31) that accommodates the plurality of divided cores (10) and the core gap member (20); and a coil (90) wound around the heat-dissipating case (30, 31). The heat-dissipating case (30, 31) is configured from a material having a heat transmission rate of 100 W/(m⋅K) or higher.
