20120218066 | REACTOR - Provided is a reactor having a small size with consideration of loss reduction. A reactor | 08-30-2012 |
20120299678 | REACTOR - Provided is a reactor including a coil, and a core having an inner core portion arranged inside the coil and an outer core portion covering the outside of the coil. The inner core portion of the reactor has a higher saturation magnetic flux density than that of the outer core portion. The outer core portion has a lower permeability than that of the inner core portion, and is made of a mixture of a magnetic material and a resin. The case has a heat-transfer portion at an inner wall surface, as a heat-radiation structure for at least one of the coil and the inner core portion. With the reactor, even if the outside of the coil is covered with a core member, heat generated in the reactor can be effectively dissipated. | 11-29-2012 |
20120313740 | REACTOR AND METHOD FOR MANUFACTURING REACTOR - Provided is a reactor including a core; and a case housing the coil and the core, the core including an inner core portion arranged inside the coil and an outer core portion partly or entirely covering the outside of the coil, the outer core portion being formed of a mixture of a magnetic material and a resin. The coil is arranged such that the axial direction of the coil is substantially parallel to a bottom surface of the case. The difference in concentration of the magnetic material in the outer core portion in the axial direction of the coil is smaller than the difference in concentration of the magnetic material in the outer core portion in a direction along a side wall of the case. With the reactor, even if the outer core portion covering the outside of the coil is formed of the mixture of the magnetic material and the resin, a desirable inductance value can be easily achieved and the reactor can have good heat radiation performance. | 12-13-2012 |

20130114319 | REACTOR - A reactor having a good heat dissipation effect is provided. The reactor includes one coil formed by winding a wire, a magnetic core arranged inside and outside the coil and forming a closed magnetic circuit, and a case for housing an assembly of the coil and the magnetic core. An end surface of the coil has a race track shape, and the coil is housed in the case such that the axial direction of the coil is parallel to an outer bottom surface of the case | 05-09-2013 |

20140140111 | REACTOR, CONVERTER AND POWER CONVERSION DEVICE - A reactor includes a coil formed by winding a wire, and a magnetic core in which a closed magnetic path is formed by both an inner core portion inserted in the coil and an outer core portion covering outer peripheral surfaces of the inner core portion and the coil. The outer core portion is formed of a mixture containing a magnetic material and resin. One of the coil and the inner core portion has an exposed portion where a part of the outer peripheral surface is not covered with the outer core portion, and at least a part of the exposed portion is in contact with a heat dissipation layer provided in a heat dissipation plate. | 05-22-2014 |
