Abstract
[Problem] To suppress the number of man-hours required to handle design changes accompanying a change in heat generation in an internal unit stored inside an electric device. [Solution] The present invention includes: at least one internal unit, which is a heat generating body and has a prescribed cross-sectional external shape; at least one heat conduction unit, which is a good conductor of heat and has a prescribed cross-sectional external shape; and a device housing in which two or more of the internal unit and the heat conduction unit can be stored in a state of being adjacent to each other with the prescribed cross-sectional external shapes thereof overlapping each other, the device housing thermally connecting to the stored internal unit or the stored heat conduction unit.
