Title:
REACTOR
Document Type and Number:
WIPO Patent Application WO/2012/066938
Kind Code:
A1
Abstract:
This reactor (1) is provided with an assembly (10) equipped with a coil (2) and a magnetic core (3) on which this coil (2) is disposed and a case (4) that houses this assembly (10). The case (4) is provided with a bottom plate part (40) that is affixed to an affixing object when the reactor (1) is installed on the affixing object, a side wall part (41) that is attached to the bottom plate (40) and surrounds the periphery of the assembly (10), and a heat dissipating layer (42) formed on the inside surface of the bottom plate part (40) and intervening between the bottom plate part (40) and the coil (2). The bottom plate part (40) is constituted of aluminum and the side wall part (41) of an insulating resin. The heat dissipating layer (42) is constituted of an adhesive with high thermal conductivity and superior insulating properties. In addition to the bottom plate part (40) being a different material from the side wall part (41) and the heat dissipating layer (42) being able to be formed easily, the bottom plate part (40) can be constituted of a material with superior heat dissipation. Because the coil (2) presses uniformly on the heat dissipating layer (42) because of an insulator (5), the heat dissipation is even more superior.
