Title:
REACTOR
Document Type and Number:
WIPO Patent Application WO/2011/052600
Kind Code:
A1
Abstract:
Disclosed is a reactor with a small number of components, which is easy to assemble. The reactor (1) comprises a coil (2), further comprising a pair of coil elements (2a, 2b); and a core component (3), further comprising a pair of intermediate core parts (30) whereupon each respective coil element (2a, 2b) is arranged. The core component (3) is formed in a ring shape, assembling intermediate core sections (31) that configure the intermediate core parts (30), a pair of end core sections (32), which sandwich the intermediate core parts (30) that are arranged in parallel, and an interstitial material (3g) that is positioned between the core parts. Clamping surfaces (321) of the respective end core sections (32), which sandwich the intermediate core parts (30), are configured as flat surfaces, and installation side surfaces (320l) of the end core sections (32) protrude beyond installation side surfaces (31l) of the intermediate core sections (31). The interstitial material (3g) is interposed between the end core sections (32) and the intermediate core parts (30), and the relative permeability of the interstitial material (3g) exceeds 1. As each core section has a simple shape under the present configuration, the reactor has a small number of components, with a portion of the core component (3) having a protruding shape.
