Title:
REACTOR AND METHOD FOR MANUFACTURING REACTOR
Document Type and Number:
WIPO Patent Application WO/2011/104975
Kind Code:
A1
Abstract:
Disclosed is a reactor provided with: a coil; a core which has an inner core part disposed inside the coil and an outer core part covering the outside of the coil; and a case which houses the coil and the core. The outer core part is formed from a mixture of a magnetic material and a resin. The coil is arranged with the axial direction thereof being substantially parallel with the bottom surface of the case. In the reactor, the difference in density of the magnetic material in the outer core part is reduced in the axial direction of the coil in comparison with a direction along a sidewall of the case. A desired inductance value can therefore be readily achieved and the reactor can have excellent heat dissipation properties even if the outer core part covering the outside of the coil is formed from a mixture of a magnetic material and a resin.
