Abstract
A radiation container where a noise filter unit is sealed and accommodated with a resinous insulation material having a thermal conductive characteristic nearly equal to that of the radiation container, and a driving unit are directly installed on a radiating fin, whereby heat generated by the noise filter unit is efficiently dissipated on the radiating fin, and a necessary insulation characteristic is obtained.
Claims12
A power converting device converting power supplied from a power source, and controlling an electric appliance, comprising:
- a noise filter unit removing a noise component occurring in the device itself;
- a driving unit having a function for rectifying the power supplied from the power source via said noise filter unit, and a function for controlling the electric appliance;
- a radiation container that is configured by a substrate on which a thin-film resinous insulation layer and a metal plate are stacked, and has a predetermined thermal conductive characteristic and an insulation characteristic;
- and
- a radiating substrate, wherein
- said noise filter unit is sealed and accommodated within said radiation container with a resinous insulation material having a thermal conductive characteristic nearly equal to the thermal conductive characteristic of said thin-film resinous insulation layer of said radiation container, and
- said radiation container accommodating said noise filter unit, and said driving unit are directly installed on said radiating substrate.
